Re: Zoning Lot Designation
City of Chanhassen Public Works Facility — 7901 Park Place
PID 25-1930050 & 25-1930060
Dear Ms. Lemke:
This letter is to request that the above -referenced two parcels be placed under a
single Parcel Identification Number.
The City of Chanhassen has no objection, pursuant to Chanhassen City Code
Section 20-903, to combining Lots 5 and 6, Block 1, Chanhassen Lakes Business
Park 5'b Addition, PIN 25-1930050 and PIN 25-1930060 , respectively, into a
single zoning lot. These two lots are under single ownership. Please revise the legal
description for the property to include both parcels' legal descriptions and combine
under a single parcel identification number with a property address of 7901 Park
Place.
Hereafter, interior lot lines within the zoning lot shall be disregarded in applying
setbacks and other zoning ordinance standards. Additionally, the lot may not be
subdivided without complying with the city's subdivision ordinance.
If you have any questions, please feel free to contact me at (952) 227-1131 or
bgenerous@ci.chanhassen.mn.us. Please send verification with the new PIN tome
once the property has been combined.

Public Works Gas PumDs
The gas pumps are located north of the building. Views from Park Place and the south are screened by
the building. The area along the north and west is screened by trees and a change in elevation (there is
more that a 10 foot drop). The gas pumps will be fully screened.
Should the city elect to use a canopy, I believe we should use the same color as the window frames.

City Council Meeting - January 26, 2009
anything's possible, to answer the question but I think Mr. Gerhardt was right too. It's a cost of
funds and we'd have to take that into account since the city is up -fronting the cost for the
assessed portion as well as for the taxpayers. Obviously the taxpayer portion is a cost to the
taxpayers but if we're up -fronting the costs from an assessment portion too, basically the city
taxpayers are playing banker at that point for those homeowners. It's a policy that we have had
and I think it's a good policy to allow property owners with assessments to pay them off over
time, but it should be done at a fair interest rate, and that's why I'd like to look at our practice
with the interest rate but then make sure that we're being fair to all parties and consistent. But I
think moving forward this evening. Authorizing the plans and specs, specifications for all three
of these project areas makes sense. I think it's the right thing to do. I think once we receive the
bids back we'll be able to review at that time the true costs. We'll have better information.
We'll also have two more months of economic information and I don't know if that's going to
give us more answers or more questions but we can review it at that time and I think that's a
prudent thing to do to keep this project on track so that we can, if we want to move forward we
have the ability to move forward. So unless there are any other questions there's been a motion,
a resolution that's been distributed to the council. If there are no other comments, is there a
motion to adopt the resolution?
Councilman McDonald: So moved.
Mayor Furlong: Thank you. Is there a second?
Councilwoman Ernst: Second.
Mayor Furlong: Made and seconded. Any discussion on the motion, or the resolution?
Resolution #2009-04: Councilman McDonald moved, Councilwoman Ernst seconded to
adopt the resolution authorizing the preparation of plans and specifications for the 2009
Street Improvement Project 09-01. All voted in favor and the motion carried unanimously

Kate Aanenson: I'm kind of combining them both if that's okay.
Mayor Furlong: Okay, absolutely. Ms. Aanenson, please go forward.
Kate Aanenson: As you indicated Mayor, members of the council, there are two separate reports
but I think to put it in context I'd like to just kind of show where the site plan is for you and
everybody else.
Mayor Furlong: Very good, thank you.
Kate Aanenson: So our subject site, 7901 Park Place is the proposed new public works facility.
This is located, maybe someone can point out on the aerial where the current public works is.
It's just north of the current public works, thank you. South of Highway 5. Also south of
Paisley Park there adjacent to Audubon Road. The site itself is actually 11 acres. If you look at
the floor area ratio we're using less than, significantly less than half the site. It's heavily
wooded. If you recall last year you did give a grading permit approval for the site so there has
been grading on this site, but the nice thing about this site with the wooded area against
Audubon, it does provide a natural screen for the setting of the subject site itself. So with those
I acres it's actually two lots. This subject site was platted, there's a history in the staff report.
The one I'm just going to refer to is the grading permit that I mentioned back in September of
2008 and then in March, 1986 the City Council approved the Chan Lakes Business Park #5
which these two lots were created. So within those two lots, getting access off of Park Road is
how this would be served. There was a utility easement so this is the first action that requires a
public hearing tonight would be the vacation of that utility easement. And in that staff report,
when this Chan Lakes Business Park 5`s Addition was created the utility easement was put in
place, and so since that time reviewing of the document that was filed in 1986 which showed the
sanitary has been abandoned so that's no longer there so in order to put this building over this
site we do require vacation of that utility easement so staff is recommending that. So I don't
know if you wanted to wait to the end to kind of go back and circle back to that motion, I'll just
go ahead and continue with the rest of the report if that's okay.
Mayor Furlong: That's fine.
Kate Aanenson: Okay. So what I'm showing you now on the rest of this project is the
remaining portion of the site so again keeping in mind that this is just the part that the building's
sitting on. Again this is adjacent to the creek itself on the north side. Maybe I should go back
and just talk a little bit more of context of this site. If you look on Park Drive. If you look on the
east of Park Drive you see there's an existing storm water pond that was created there. Actually
the creek runs through that. A meandering creek which affects some of the boundaries with
variances which I'll talk again about in a minute. There's also a wetland to the south. If you see
the two yellow highlighted parcels, there's a wetland and that probably, that does, that goes into
the subject site and that also, there's a variance on that too. So I'll go through in a little bit more
detail how that's affecting the layout of the site. And then again in reviewing this, trying to
preserve as much of the trees, working in between the creek and the wetland were some of the
criteria that was put in place. So there was several iterations of the site plan. Again while this is

a city initiated project, we hold ourselves to the same standards as we would with any other
developer so the planning staff working with engineering made some modifications to the site
plan itself. You can see the wetland, I'm not sure this is, on this portion. Maybe you can show
that Paul where the wetland is. Thank you. That's the one wetland that's, we're seeking
variance from, and I'll show that in a little bit more detail what percentage that is, but in order to
get the drive circulation through the site and then you can see the creek to the north. Kind of a
meandering, very circuitous as it works through the property right now. So some of the
functions that were needed for this building, on the original site plan it was laid out in meeting
with the planning staff we all try to figure out what needs to happen to get the circulation for the
trucks to go through the bays. Provide public access. This is an opportunity for a voting place
so we want easy access for public not to have to go into the back. Also providing screening for
some of our outdoor storage that the city needs. The public building right now there is a
significant salt storage that is a requirement so that same building, that same structure will be
place on this site so trying to find an adequate place for that. So those are all the functions of the
public works itself that laid out how this should fit on the site, so from the original site plan we
worked through some of those issues and modified it to the plan that is being proposed and the
Planning Commission did make a recommendation too. The Planning Commission held their
hearing on January 6`s of this year and they had some concerns regarding the implications for the
wetland and also the creek setback. We were holding ourselves to the same standards so we had
a good discussion on that itself. And the way the creek is sitting now and how it's being used,
there's direct flow into that creek right now so with this plan putting the curb in place,
monitoring the drainage, that will actually improve the quality of that site itself, and I think my
next slide shows the implication area. So you look at that brown minor area on the site. That's
where the creek is. Not by the garage but on the east side. And then, north side. And then on
the southern side by the wetland is a part that the wetland setback. And in looking at this area in
the grading there was significant grading that's addressed in the staff report. In order to
accomplish avoiding that wetland, significant grading would have to take place and more tree
loss so looking at that area, it's always that conflict between the wetland impact, additional
grading and tree loss, and again some of that tree provides a screening from Audubon. If you go
now when you drive by the public works facility on Audubon, as you come over the bridge, you
look right into that storage area so really this is a nice feature of this site is you won't see that.
That outdoor storage so there is an impact there. Again providing the storm water pre-treatment.
Saving, there's a significant tree that we're working to save. Coming around the, maybe you can
show that Paul. There's a pretty significant oak tree right there we're also trying to save. So
those are some of the features that we looked at in providing this layout itself. The Planning
Commission as we went through those issues concurred that that seem to make some sense.
Again the anomaly of the creek meandering through there. Working through to clean up,
providing additional vegetation to control the runoff that's going to the site were all included in
that. So there's the landscaping plan. Again providing for the mitigation and this additional
storm water and the circulation to the site. There will be a retaining wall up against the Paisley
Park studio site where those storage bins are. Kind of the area where there's additional storage.
So, and I think the highest part of that would actually be approximately 14 feet. That's laid out
in the staff report too. And that was one of the issues that we worked through to address too.
Staggering that to get additional landscaping in that back area there also providing that buffer.
There is a natural buffer as the change of topography from the back of Paisley Park to this site
but also working that we're holding ourselves to that same standard. So again meeting the tree
27
City Council Meeting - January 26, 2009
preservation area does provide for that landscaping requirement. There was some additional
landscaping to be put in place. So with that if there's any, isn't any more questions on the site
layout itself then I'll move into the architectural standards and if I get any questions.
Mayor Furlong: Do you want questions now?
Kate Aanenson: If there's any questions on the layout or design, of that part of it or the vacation.
Otherwise I'll move into the architecture part of the site plan.
Mayor Furlong: Any questions at this point? Ms. Aanenson, I guess we'll be getting into the
wetland impact and the creek. Can you, you mentioned that there were some improvements to
the drainage with curbs.
Kate Aanenson: Yes.
Mayor Furlong: Will, what's the, can you give us an idea of what improvements are being made
in terms of storm water drainage on this site with the improvements.
Kate Aanenson: Sure.
Mayor Furlong: There'll be impervious, increase in hard cover surface but what are we doing to
manage storm water?
Kate Aanenson: Correct. There is no, it sheet flows right now so we're putting additional
ponding in on site.
Mayor Furlong: So it sheet flows just across the site.
Kate Aanenson: Correct. Correct, and there's been a significant amount of erosion on this site
SO.
Mayor Furlong: Where does the erosion occur?
Kate Aanenson: Really throughout that whole kind of creek bed. Maybe you can show us that.
The creek bed, yeah.
Paul Oehme: Through the creek bed and then also into the wetland too.
Kate Aanenson: Yes.
Mayor Furlong: There's been erosion over there?
Kate Aanenson: Yes, because really it has been unmanaged over the years. Since the business
park was put in place and I think it's been altered over time.
Mayor Furlong: Okay.
28 j
City Council Meeting - January 26, 2009
Kate Aanenson: So by doing that we're committing to improve that and then provide any
additional landscaping, besides the landscape buffer to the wetland. And also the buffer, using
correct vegetation. Cleaning out the creek itself and providing additional landscaping and the
curb.
Mayor Furlong: When you say cleaning out the creek. Of debris and?
Kate Aanenson: Yes. Yes.
Mayor Furlong: Is it man made debris or is it natural?
Kate Aanenson: Yes, there's been a lot of dumping in over time.
Mayor Furlong: Okay.
Kate Aanenson: Yeah, so cleaning all that up, and then providing additional landscaping along
that, which would be the native. That's just representative. We're working now to put in what
would be upland type vegetation for that project so that would be the right type of filtering as we
talk about for wetland infiltration. So again we've done several of these projects in the past. For
example on, we worked with the General Mills. Remand that creek of vegetation so we know
how to do these type of projects so in-house staff we will be doing that. Working through that as
this project evolves.
Mayor Furlong: And will the runoff from the parking area and elsewhere, will that go through
storm water management to pond.
Kate Aanenson: Yes.
Mayor Furlong: So that's not just going to go straight into...
Paul Oehme: There's a regional pond that's not shown on this drawing just east of here that all
of the surface runoff from the parking lot area and the storage facility area that's going to be pre-
treated before it ends up in the creek so we're managing our storm water on this site just like any
other development and we're trying to improve upon that too and having some infiltration basins
and some bio-retention areas in this area too. We're looking at that so, so I think we're doing a
pretty good job in terms of water quality management.
Kate Aanenson: Yeah, we're meeting the standards and exceeding that, and by that I mean
because the site is devoid of vegetation because it's had a lot of sheet flow runoff. We're
actually going to increase that by helping reduce the velocity and some of those sort of things
which will help the erosion over the long term life of the creek.
Mayor Furlong: Okay, thank you.
29
City Council Meeting - January 26, 2009
Councilwoman Ernst: Kate, you have one of the proposed motions in here is, and I know we're
going to get to that later but are you still asking for the variance then?
Kate Aanenson: Yes.
Councilwoman Ernst: From the creek and the wetland?
Kate Aanenson: Yes. If you can, let's see. Those two areas are the areas that we are too close.
Where that road comes in, and then the brown area adjacent to the creek. So again, to push the
building further to the, we'd take out more trees on that west side so that was trying to figure out
which would be the best way to go on that project. That wetland is, if I go back to, sorry. Make
everybody dizzy here. Going back to this site plan you can see where that wetland falls in and
there's a significant amount of trees. And then as the city engineer indicated where that storm
water pond is already, that's where we're working with. So some of those things are in place
already.
Councilman Litsey: Which one's the regional pond?
Paul Oehme: This one right here. This one takes a good portion of this development up here and
some of the Park Road as well.
Kate Aanenson: Yeah, and I didn't point out but we're, where he was pointing to, that is also
city property. Right there. It's kind of, it looks like a big scoop. It goes all the way towards 5.
Mayor Furlong: The regional pond is on city property?
Kate Aanenson: Yes, and then that bigger piece right there is all city property, so as a part of this
project that's also where some of the creek right-of-way is too. Improving all that. So I'm just
going to back up too on where I was there. So this is the site itself. That wetland. Looking at
again the kind of circuitous meander of the creek and the site itself and then it's proximity to the
project to the north. And then you can see that tree area. It's heavily wooded right next to the
building and those are the trees that we're trying to save by not doing additional grading. And
those are very mature trees so it's always that balance of where we want to go with that.
Councilman Litsey: So you could make it work perhaps without the variance but you'd be
destroying a considerable amount of trees in the process.
Kate Aanenson: Correct.
Councilman Litsey: So you're balancing that.
Kate Aanenson: That was the factor.
Councilman Litsey: The benefits, okay.
k1r,
City Council Meeting - January 26, 2009
Kate Aanenson: Again looking at how you need to circulate through the building to get the
trucks in.
Councilman Litsey: Yeah.
Kate Aanenson: So again, the most northerly encroachment would require a 25 foot variance.
That's the widest part of that, and then would require the 15 foot variance. Excuse me, the 3.5
encroachment to the minimum wetland buffer so again we'll buffer that significantly, that area
between the road and the wetland itself. Providing that. Okay, now I'll move to the site plan
itself. This is the Planning Commission had some questions on the grading and drainage but I
think we addressed that question already. The architecture itself. I'm on page 4 of the staff
report went into quite a bit of detail of the style of the building itself. It consists mostly of ribbed
insulated pre -cast tilt up panels with exposed aggregate. With brick banding. The brick is also
larger in size and dark brown in earth tones and maybe I can switch that, I know it's a little
difficult to see that color. It also has a charcoal gray color with dark brown accents on it. So
some of the features of this, it does meet the window fenestration requirements. It also has the
clear story on the, go to this. The windows on this side which meets the fenestration
requirements. The back side where we have all of the trees, because you can't see that. It does
have some penetration through these upper story windows but that also meets the standard. So
then you've got the clear story up above where the bays are again providing that indirect
lighting. That light source which, so you don't always have to turn the lights on inside the
building itself. So over the 50% transparency the first floor office, as I mentioned, so that does
meet the requirements of the building. There is loading. The service yards. The wreckage area.
Waste removal and other things again are all screened outside which we do require of all
business so we're meeting our standard on that which is an improvement from where we are
today, where you can clearly see the outdoor storage on that site so this is a significant
improvement from the buffer, I mean from the public. And we do know that on this site too that
will be used by the public so a lot of that storage will still be in that screened area if we do use it
for voting or something like that, so it will still all be screened off to the side. It does on the
compliance page, the compliance standards starting on page 6. It does meet all the city
compliance standards except for the two variances that we did note. And if we do need
additional parking, while it's not striped, while there's an event, it can be accommodated there
with temporary markings or something of that effect. For some reason we needed additional
parking for some public event that was to be held out there. I did mention the grading and we do
have a grading permit out there now but again putting the grading and trying to do additional
grading out there would exist trees that are out there. So other than that, if there's any additional
questions I'd be happy to answer those. Otherwise there's two reports in front of you. The first
report is for the vacation of the easement. And then the second would be approval for the site
plan for the 82,500 square foot public works facility. With the variances. Oh excuse me, and
that conditional use for the outdoor storage and that outdoor storage was the structure which
holds the salt, which we have in place right now at our current public works facility. We do
require a conditional use for outdoor storage.
Mayor Furlong: Aren't there other outdoor storage bins on the north side of the property?
31
City Council Meeting - January 26, 2009
Kate Aanenson: Yes, those are screened which we do allow those sort of things. We have other
businesses have those things but this because of the size of that, it does require a conditional use.
Yeah.
Mayor Furlong: And this is, this is the same structure? The same cover that we have at our
current facility.
Kate Aanenson: Exact same structure.
Mayor Furlong: We'd just be relocating it.
Paul Oehme: Correct.
Todd Gerhardt: Mayor and council.
Mayor Furlong: Yes.
Todd Gerhardt: I'd like to just give you a short little update of how we got here. For the
public's benefit. This has kind of been a work in progress for the past oh at least 4 years or more
and our current public works facility was built in 19.
Paul Oehme: 80.
Todd Gerhardt: 80? Okay. And there was a couple of additions put on to that facility and it's
about 24,000 square feet. Through our analysis we have a need for about 82,000 square feet is
comparable to what other communities of our size. Number of miles of streets. Number of
miles of sewer and watermain that we have to maintain. That will house our utility department.
Our park maintenance department. Our street department. And our mechanics that work on all
the vehicles that we have, which are numerous, and through our analysis we presented to the City
Council this past summer, we looked at building new on other vacant lots in town. We also
looked at acquiring existing buildings throughout the community, and other communities, and
what we found when you have an operation like we have here, most existing businesses don't
allow for trucks that may come in that have been out plowing snow and the melting the occurs.
The salt that occurs, so you need quite a drainage system that goes along with that. And then the
mechanics bay, you need a variety of different types of hoists. You know our dump trucks need
a heavier hoist so there's a major improvement that you would have to put into an existing
building. And from our analysis at looking at this, we hired a private construction manager to
come in and take a look at some existing buildings and do a full cost benefit of remodeling an
existing building to meet our needs. The price of that was substantially higher than new
construction if you remember, and the true cost of that was trying to put that drainage system in.
And at the time that you get it all done, you still have a 15 or a 30 year old building that you
remodeled versus a brand new facility that you would have today with the one that's before you.
When people look at the cost of a new facility like this at the $100, there's some confusion that
goes along with that. The $100 a square foot is also includes a lot of the equipment that will be
in this facility. The hoist. The wash bay and the wand that washes the trucks down. You're also
going to have office space finished out. Desks, chairs, conference room. So when you go out
32
City Council Meeting - January 26, 2009
and look that you could buy a new building for $60 a square foot, you're buying a vacant
building that doesn't have the equipment that would be housed in there. So with that little bit of
history, kind of where we're at and any updated questions that the council has.
Mayor Furlong: Okay, thank you. Any questions for staff at this time?
Councilwoman Ernst: I have a couple questions.
Mayor Furlong: No questions at this time? Okay.
Councilwoman Ernst: No, I said I do.
Mayor Furlong: Oh you do? I'm sorry. Councilwoman Ernst.
Councilwoman Ernst: That's okay. Kate, when you were talking about the wetlands a couple
questions I have are, can you tell me how close the underground fuel storage tanks are to Riley
Creek?
Kate Aanenson: Would you like to answer that please?
Paul Oehme: I don't have a scale on me.
Mayor Furlong: Can you tell us where on the site plan?
Paul Oehme: Well the underground fuel tanks are right here and the creek is right about here.
I'm venturing to say it's probably 200 feet away from the creek currently.
Councilwoman Ernst: Do you feel that's enough from, to prevent any kind of contamination?
Paul Oehme: Well I mean these, the new tanks, and the architect's here. He can probably speak
to it more than I can but I mean they're tested annually in terms of leakage. These things are, the
fiberglass it not going to rot out on us. They have a long life expectancy and I'm not too
concerned about ground water, or ground contamination from these new tanks. They're highly,
very structurally built and solid so I don't really see a problem there. And the only aspect of
contamination that I would be concerned with, and that we are trying to address too is surface
contamination. Say a gas tank overfills and dumps out into the parking lot. How do we address
that so we're looking at that through our best management practices and storm water
infrastructure that we're having on the site here, instead of try to mitigate those issues and try to
capture them on site before it actually ends up in our storm sewer treatment pond and eventually
into the creek.
Councilwoman Ernst: Okay, and where would you be storing the chemicals? Like salt and that
sort of thing. What part of the building?
Paul Oehme: Yeah, the salt would be, the planned location for the salt storage facility is
currently right here and that's completely housed. I mean there's going to be walls as currently
a]
City Council Meeting - January 26, 2009
as today on our site. Walls on 3 sides and then there's a, kind of a fiberglass or a meshed type of
material, cover that covers the entire salt storage facility too, so it faces south so you know
prevailing winds from the north and to the west, you know it's well guarded against that. Plus
any rain events, it's all paved underneath there as well too so there wouldn't be any salt
infiltration into the soils. And plus it's on a flat surface so any runoff spillage is, there's really
no place for it to go except on site and we'd get in there and sweep it up or probably... and re -pile
it into piles so.
Councilwoman Ernst: I know you showed it to me before but I couldn't remember what the
relationship was between the creek and the storage. Can you tell me if by any chance we looked
at MTS building, or existing buildings? We did?
Todd Gerhardt: Yep.
Councilwoman Ernst: And that was the drainage issue as well?
Todd Gerhardt: That one had drainage and then kind of the flowage, the truck driving through.
You had posts every 30 feet?
Paul Oehme: If that.
Todd Gerhardt: If that. So there wasn't adequate drive through. You know trucks would have
to back around inside. Same thing with the Teleplan building.
Councilwoman Ernst: Thank you.
Mayor Furlong: Any other questions?
Councilwoman Ernst: No, that's it.
Mayor Furlong: Questions at this time? Let's start by opening up the public hearing with regard
to the vacation.
Kate Aanenson: Correct on the utility easement.
Mayor Furlong: Okay. If you can go back up to that slide. Who's ever controlling the pictures.
The specific issue here, and this is a public hearing with regard to the request to vacate this
easement and as I understand it there are no existing utilities in this easement? At this time.
Paul Oehme: Yeah, they have been removed.
Mayor Furlong: They've been removed?
Paul Oehme: All the public utilities have been removed and there's no private utilities out there.
34
City Council Meeting - January 26, 2009
Mayor Furlong: No private utilities? No anticipated need in the future for having this? Okay.
So let me open up the public hearing with regard to the proposal to vacate the easement and
invite any interested parties to come forward and comment at this time. Okay.
Patrick Neuman: I didn't have anything prepared but 1 used to.
Mayor Furlong: If you could state your name and address sir for the record. Thank you.
Patrick Neuman: Okay. Patrick Neuman. I live on 740 Chippewa Circle, Chanhassen. And
I've been getting wood chips out of that lot for a number of years. Since we moved here to
Chanhassen in 2000, and I appreciate the effort that the project is involved in trying to save the
woodlands because I think there are some really nice trees there. There's some nice maple trees.
I remember some people going back and trying to collect maple syrup through there. I hope
you're aware of those trees.
Kate Aanenson: Yes I am. I didn't know they were doing syrup though.
Patrick Neuman: I'm a little bit concerned about that this is a really nice, I mean location with
Riley Creek, isn't that the creek that comes out of Lake Ann also?
Kate Aanenson: That's correct. That's correct.
Patrick Neuman: I mean it's a, everyone knows that Lake Ann is a special lake for Chanhassen
so the water quality in the creek you know is good and I mean it would be good if it isn't
polluted below that area you know, so I think it's important to manage this area well, you know
for wildlife, and I have seen a lot of wildlife in this area while I was getting my wood chips, with
approval from the public works people. They give you a key to get in. Now I go over to the
Landscape Arboretum for my wood chips, but anyways I have seen a lot of owls and
woodpeckers and wildlife in that area and so you know it's kind of subdividing it by putting a
building there you know and so I think the city needs, Chanhassen needs to keep in mind that we
need to keep some areas for wildlife that are not broken up into little pieces because certain kinds
of wildlife of course need more space. Just they won't be here if there isn't that kind of an
environment. And I'm also interested in if you're going to be putting in prairie vegetation?
Kate Aanenson: We're going to put in is a more native that would be correct for the creek bed
itself to stabilize that. Maybe I can go. I think the nice situation that we have here is what we've
learned when we did the Highway 5 corridors. There's an actual deer movement corridors so
one of them right now is going to be the creek itself, and we're preserving that. The city still
owns that piece of property and by revegetating it should continue to make it a nice deer
corridor. And then again through the wooded area in the back will still maintain the corridor for
area for deer to go into in the back of the building while all the trees still are maintained so I
think by putting that natural vegetation to actually improve that creek from eroding should be
helpful.
Patrick Neuman: Okay, thank you.
35
City Council Meeting - January 26, 2009
Todd Gerhardt: Mayor I'd just like to point out, there are very few trees, if any that will be
removed that aren't already gone today. So what you see there today is pretty much what's
going to stay.
Mayor Furlong: Thank you. Normally in this process we would have the applicant provide
comments but since the city's the applicant, they've been doing it right along so let's go ahead if
there are other individuals who would like to provide public comment on either the drainage
easement removal or the site plan in general, that'd be fine too.
Tom Devine: I'm Tom Devine. I live at 7640 South Shore Drive. This evening I came really to
touch on really two issues as it relates to this, and some of it really relates to part of the process
that's already been completed and done, and the rest really relates to the pieces going forward. I
want to be very respectful of the work that Todd and Paul and Todd have done and the rest of the
city people have done on the project. I understand the need for the project. I certainly
understand it's been extremely well planned. It's a beautiful building. It's a nice city amenity
and all of those things. What I would like to touch on prior to the granting of the variances,
which as I understand have to be completed, and I'm asking that the City Council really give
some thought to is a couple of things as it relates to where we are today. If we look at the
extraordinary things that have happened in the last 60 days, 30 days. 60 days. Relative to the
economy. I spent quite a bit of time up at the legislature on a variety of matters and I do, I am
involved in seeing some construction projects and the re -bidding and that sort of thing. Much
has happened here in the economy here in Minnesota particularly over the last 30 days and when
we saw the announcement the Governor made earlier this month about the shortfall. The $5.2
billion dollar shortfall, I'm told that that budget shortfall is going to increase both in February,
March and April with the additional layoff s and all of what's happening. There's a significant
thing that's unfolding here in front of us and I think it's something that we need to look at, and I
want to talk about what the impact is just purely to Chanhassen as it relates to this. If we look at
you know moving towards 9% unemployment and all of that, this type of project is obviously a
good project. It's a stimulant type project and some of the rest of that. But the issue that I'm
most concerned about is the 3 corporate jets that flew to Washington D.C. and I say that as the
example. The 3 jets that flew from General Motors, Ford and Chrysler out to a hearing in
Washington D.C. It had kind of an ill effect in terms of what they were going out to do. We're
asking the public right now to undertake, and as I understand the bonds have been sold or
whatever for do an $8 million dollar project. At the same time we're going to be spending time
at the legislature, the city will be, the county will be, and looking for additional funds. State aid
funds that are going to come down to the city and the county. The school districts are going to
be up there looking for funds and I'm looking at what does this look like at the same time we
have a front page picture in the Villager at the point that this starts of building a new $8 million
dollar facility in part to store snow plows in and equipment and trucks and I wonder is now the
time to be doing it. I don't question the need and I don't question the quality of what we're
building or anything. What I'm concerned about is the appearance and the timing that we're
talking about. We're talking about breaking ground, starting a project in April. At the same time
the legislature will be moving towards a decision process to decide what kinds of funds we're
going to be getting. You know the Governor's already announced that those workers that are
with the state, city and county. Anybody that gets raises is going to be impacted negatively in
how he divides up his pie to put, you know to circle down. I don't know what control he has but
36
City Council Meeting - January 26, 2009
I sat in speeches where he's given those things and I'm concerned about what the impact of all of
this is going to be. And so that end when we look at these various things, you know we know
building permits are going to be you know significantly reduced here this year and next year. I
look at this and say I don't know what the bonding went out at but what is the possibility of
looking at re -doing the bonds because the bond rates have obviously dropped since October and I
also look at the issues of re -bidding and I was with one of the major contractors here in the Twin
Cities here this past week on a project that I'm involved with from my professional standpoint
and they sent the project back out to re -bid and they got about a 15% reduction in the cost of the
project over what was bid for earlier this fall. So I say to you three. Obviously you're talking
about a variance as it relates to water quality, or the water. Drainage issue and that, but there is
an opportunity in extraordinary times to take extraordinary steps and I ask you right now to
consider, is this the right time to be putting out a huge project like what we're talking about with
the kinds of costs that are involved in it at this particular juncture. So I say that in a very
considerate, polite way in terms of what you're doing and what you're undertaking right now,
but I also look at that and say is it the message that we want going out from the city of
Chanhassen you know in terms of what we're doing. I understand the project's been under, you
know we've been talking about this for a number of years. A delay of another 24 months or
whatever you know, what's the impact of doing that or waiting? The environmental, the only
other thing I would just want to say is on the environmental piece. As most of you know I've
been very involved in the water quality issues here in Chanhassen and I'm obviously a little bit
bothered by the fact that the water is going down and end up in Lake Susan, and I don't know if
anybody is here from Lake Susan this evening or not but clearly if it was over by my lake I'd be,
I'd be a little concerned about that because clearly we're trying to do just the opposite of what
you're asking for a variance for yourselves tonight on doing and so I think that that issue is
another issue that comes to mind but anyway. That's all I really wanted to say unless there's a
question.
Mayor Furlong: Yeah Mr. Devine. On the last issue, with regard to the wetland, or the variance
for the setback for the wetland. You said that's opposite of what we're trying to do across the
city?
Tom Devine: Well right now we're doing everything we can to clean up our lakes and streams
and everything and the proximity of where this project is to that, to both the creek there and to
the wetland area, if I was a private developer sitting here right now, and I understand what the
needs of the city are different than the private developer but if I was a private developer, how
would this project be looked at right now in terms of the water quality issues in terms of what's
being proposed?
Mayor Furlong: And that's a fair question. It's a question I asked staff earlier today and so I'd
like them to respond to that question as well.
Tom Devine: Okay. And I'm saying this very respectfully. I'm just you know, we're all here to
talk and we're in the same boat you know.

City Council Meeting - January 26, 2009
Mayor Furlong: That's fine. And I think if we can talk, you raised some issues about the timing
of the project based upon economic conditions as well as other factors going on in St. Paul, and
then also the wetlands so maybe I'll defer to staff.
Kate Aanenson: Sure, again those areas shown in brown, we're not impacting the wetland itself.
It's the buffer area requirement so again it's our intention on those two areas, the small brown
area adjacent to the creek. So that's the buffer setback area that we're impacting. Not the creek
itself.
Mayor Furlong: We see wetland alteration permits from time to time.
Kate Aanenson: Right, this isn't a wetland alteration.
Mayor Furlong: This is not an alteration?
Kate Aanenson: It's the buffer requirement. So again if you look at the function of that building
coming off, again we're trying to work out a couple of trees that are down there and Paul pointed
that significant oak that's to the entrance there, but we're going to provide buffer in that area.
Substantial buffering in the area where they come out of the, maybe you could show Paul on the,
either side of that drive. Yeah. Right through, yeah. Either side of that driveway we'll have
significant buffering and picking up that area and that existing trees that are there that we're
going to try to work around so we're not impacting the wetland itself. It's the buffer. And I
think the biggest issue that we've talked about there is how the water is being conveyed and
that's to the creek and that's where over time that's significantly degraded and that's what we're
going to spend the most amount of time is looking at that. We have experienced doing other re -
re -meandering projects and not that we're going to re -re -meander it but to stabilize those... I
think that's what some of that sediment is so we're going to try to reduce the velocity and the
volume as it goes through there. Slowing it down. Putting the curb along that parking lot itself
because how it functions today with some of that source that gets put out there, that's what's
going into the creek so I think it will significantly improve what's going on out there today.
That's our goal.
Mayor Furlong: And to follow up on Mr. Devine's question too. How did the staff look at this?
Did staff look at this any differently than if it had been a project a developer...
Kate Aanenson: No, again you have to look at how the function is because no matter what, if
someone went in there that wanted to circulate, this is an industrial. It's zoned IOP. It's an
industrial office building. Pretty much everything that's out there has some traffic entrance to it
where they would do storage. If you look at our industrial park. Back up. Even bay storage is
pretty typical of an industrial building so that would probably be fitting on here so then again
we're back to it's the implication of the trees as we heard earlier. A significant wildlife corridor.
And trying to manage that the best we can. Saving some of those trees that are also adjacent to
the building. That's what we were trying to measure and we went around with numerous designs
with the architect trying to get that, what we believed was the best fit on this site with the least
amount of impact.
M
City Council Meeting - January 26, 2009
Mayor Furlong: Okay, thank you.
Todd Gerhardt: Mayor, I'd just like to point out one other point on that is the site coverage. You
know if this property was under private ownership, most developers would maximize the
investment into this property and our site coverage is.
Kate Aanenson: .16.
Todd Gerhardt: It's substantially below what the private sector would probably do if they owned
this piece of property. And that was one of the reasons why we acquired it was to ensure that
that large stand of trees stayed in place. And the other added benefit, it acts as a great buffer to
us, the recording studio to the north and some of Paul's dirt piles that people are objecting to as
they drive by, but you know we really put ourselves through the same rigors we would any
private person that would come through and Terry did a great job of working with us and doing
some creative things that even for the impact that we're doing in those buffer areas.
Mayor Furlong: Okay. Thank you Mr. Devine. Other comments?
Mary Borns: I'm Mary Boms, 7199 Frontier Trail and I am on the north side of 5 far away from
Lake Susan but I am concerned mostly with the environmental issues and the close proximity to
the lake. And it just feels to me like we're not meeting our own standards and it seems only a
year ago that we shorten our buffer setbacks and now we're trying to get a variance to the
shorten, what was amended once before. I just, I don't think that we should be making the rules
as we go. If it's a rule, it's a rule. In looking at the picture, Kate can you tell me what the
percentage of impervious surface is?
Kate Aanenson: Sure. It's, if you go to the, do you have a copy of the staff report?
Mary Borns: No.
Kate Aanenson: Okay. On the first page of the staff report the entire site is 11.95 so of that the
floor area ration which is the building footprint is .16. So it's less than a quarter of the site so
that kind of goes back to again what we were trying to say, if you had a typical developer, they
would probably maximize the site and gone back further into the trees so that was what we were
trying to balance. Some of that wildlife corridor and go back to, so this entire site. So if you see
where the building's sitting on that, where the.
Mayor Furlong: What's the percentage of impervious surface coverage allowed in this zoning
area?
Kate Aanenson: 70 percent.
Mayor Furlong: 7-0?
Kate Aanenson: That's correct.

City Council Meeting - January 26, 2009
Mary Boms: And if the variance doesn't, if the variances don't pass we still go ahead with the
project?
Kate Aanenson: That would be up to the City Council to make a decision on that.
Todd Gerhardt: If City Council doesn't approve the variances, the project cannot move ahead
unless we reconfigure the building and move it into the trees.
Mary Boms: Well and that's my question is, you know would they make a different plan or
would they just not go ahead with the project?
Todd Gerhardt: It's something we'd have to evaluate.
Mary Borns: Was it necessary in the steps that we took for the variance to come last. It feels
like there's been so much has gone forward and worked into this project and for us now to say if
the variance didn't pass we have to start all over. It feels to me like we kind of put the cart
before the horse in getting this far without...
Kate Aanenson: Yeah that's a good question. Typically when we do a variance with a project
they come together so you can see how it lays out. What your options are. As we indicated
before we were trying to tie that into the entire site so you can see how it lays out on the site.
The amount of grading. If you do additional grading and the tree loss so you really have to see
how the layers work and the grading and drainage so, to look at a variance without looking at
how the site lays on there, you really need to see it all together so that's pretty typical on a
project. It wouldn't be any different if someone was to do an addition to their house. You'd
have them actually draw it out on the house to see how that would actually fit to look at your
options so that's pretty standard.
Todd Gerhardt: Mayor, council. If you're referring to the bond sale, we were trying to
anticipate interest rates going up at that time when we had the sale in November. We had 9
bidders on our bond sale and we got 4.38 if I remember right interest rate on those on a 20 year
issue so. AAA rated Bloomington had a 4.5% interest two weeks prior to that so that was the
reason we moved ahead on that.
Mary Borns: No, I don't mean to be critical at all of the funding on it. I just think there's been a
lot of steps and a lot of time and a lot of effort involved in a project that may not get off the
ground if the variance isn't passed and that's all I'm saying is maybe that should have been
looked at more firmly in the first place. I don't think that it's an ideal site by any means and I
understand that the city already owns it. I would think that they could get a really good price for
that particular site being that close to Lake Susan and the bike path and in such a nice area that
maybe there's another site in town that would work better for us, but I realize that's already been
figured out last fall. So I guess that's all I really have to say. My main concerns are the
underground fuel tanks. Same as Vicki Ernst, Councilwoman Ernst indicated. Looks like the
fuel tanks and the salt are going to be the closest to the lake out of the whole drawing and I don't
like to see them on the site at all. There's going to be toxic waste from the oil. Some gas. Some
exhaust. The cleaning of vehicles. Things that you talked about. You talked about washing the
40
City Council Meeting - January 26, 2009
vehicles inside and it is, it does have to drain so those are my main concerns. Thank you for
your time.
Paul Oehme: To address, yeah.
Mayor Furlong: Please, address some of those questions.
Paul Oehme: Some, the washing of the vehicles there. We do have a fairly significant sump
man hole that's planned for this area. It separates out the solids from the liquids and that water
does not leave this site through storm water conveyance system. That PCA rules that that has to
go into the sanitary sewer system so that doesn't even make it to the lakes so a lot of that
washing materials and those hazardous, potentially oils and other debris would not even make it
into the storm sewer system so.
Mayor Furlong: So is it, are we going to be washing any vehicles outside in the parking lot
where it would drain to the storm water or would they all be done in such a way that any water
will be contained within the sanitary sewer system?
Paul Oehme: I wouldn't say in all cases it's going to be done inside but there would be some
cases that it would have to be washed outside but in terms of the heavier vehicles, the salt laden
vehicles in the winter time, all those type of really contaminated vehicles would all be washed
inside. The only vehicles I can think of that potentially could be washed outside, maybe a skid
loader that gets muddy. A street sweeper that you have to chunk off some dirt before we get into
the building but vast majority's going to be done inside where again the conveyance system does
not go to the storm sewer. It goes to the sanitary sewer.
Mayor Furlong: Lake Susan's been mentioned a couple times. I've heard Riley Creek which
runs along the east side. How far away are we from Lake Susan?
Kate Aanenson: I'm not sure if it's on this other slide that would be better. There you go. So,
there's the conveyance.
Mayor Furlong: So about half way between Lake Ann and Lake Susan.
Kate Aanenson: Yeah. And again I just want to, as the City Manager pointed out, we haven't
maximized the site so you know you could have a significant larger parking lot on there so at the
70% hard surface coverage. So we don't have an ordinance that says you can't down any trees.
What we say is if you cut down a lot of trees, then you have to replace them with a significant
penalty but there is no requirement you can't cut down trees to develop a site.
Paul Oehme: And again all the storm water from the development is going to be directed right
into the storm water treatment pond. Regional storm water treatment pond. A very big storm
water treatment pond. Curb and gutter around the entire site so they're directed into the catch
basins and into the ponds so we are going to get I think better actually water quality from the
development than pre because of the erosion that Ms. Aanenson had mentioned before and some
of the other debris that's washes into the creek right now so.

City Council Meeting - January 26, 2009
Mayor Furlong: Thank you.
Todd Gerhardt: Mayor, council members.
Mayor Furlong: Yes.
Todd Gerhardt: It goes through two storm water ponds. The one on -site just to the right of the
cul-de-sac and then it drains into the pond next to Lake Susan and then into Lake Susan.
Kate Aanenson: Yeah, that industrial pond.
Mayor Furlong: So the storm water pond, I guess that's another question. The one that we had
mentioned, maybe can we zoom in where we can see that storm water pond closer. I don't know
if you can zoom but if you can.
Kate Aanenson: I think Laurie, can you just put the zoom in on the.
Laurie Hokkanen: Not when it's on...
Mayor Furlong: If you can't zoom in on that one, there's another picture further down where we
saw the storm water pond earlier.
Kate Aanenson: Oh! Was it the next slide or.
Mayor Furlong: Yeah, back to that slide.
Kate Aanenson: Okay.
Mayor Furlong: That's the storm water pond there?
Paul Oehme: That's correct. This one right here.
Mayor Furlong: Tear drop. That drains from there into the Lake Susan storm water pond to the
north west of Lake Susan?
Paul Oehme: Yeah.
Mayor Furlong: Okay.
Paul Oehme: It goes through this storm water area here as well. It's all overland flow as well.
There's some other storm sewer ponds along the way so.
Mayor Furlong: So it'd be all part of your current system in that area?
Paul Oehme: Exactly.

City Council Meeting - January 26, 2009
Mayor Furlong: Sir.
Jeff Oertel: Mr. Mayor, council. I thought I'd interject and hopefully not belabor the meeting
too long but my name is Jeff Oertel and I'm the head architect on the project and for the record I
reside and work out of St. Paul. And we had actually discussed this project in a work shop last
year but I wanted to address a few things that seem to be a concern. The fuel tanks and the
fueling system are so highly regulated by the federal government that I think all the concerns that
you know, that we've heard tonight have been addressed and realized by thousands and
thousands of parties and municipalities. The tanks are a double wall tank and they have very
sensitive sensors strapped around the entire, entire unit. If there's an infinitesimal leak of fuel,
either diesel or regular gasoline that would leak out of the inner chamber, it should be sensed and
immediately go to a panel that's in the building. A monitor would go off and the containment
then would then, the innertiscial area would be equal to that of the greatest volume of fuel that
could be in the tank and then contained. As was indicated earlier the tanks are made out of
fiberglass and in addition to the tanks they are double wall piping and incredible amount of detail
that goes into these tanks so these systems are pretty safe as they come. I'd also like to give a
view point, my view point on a few other things. Again I'll be quick. The City of Edina has
gone through the process of looking at, I think we're up to 8 buildings trying to, you know look
at a building that would serve as a new facility and in that case the city would love to have a new
site. An open site. A site the size that's necessary to bring all their parties together and there's
just no site available and so we finally glommed onto a building that appears to be pretty
reasonable. Council's aware of it and reviewing that project right now over the last 3 months.
The cost of that project is approaching a new building and it's probably close to equal to a new
building and after it's all said and done, it's a renovated old building as was indicated earlier.
My perspective on the site and the quality of the storm water and the creek is that, my opinion is
after this project is completed, if approved by council, the quality ultimately of that storm
drainage and creek water will be improved. There's no doubt in my mind because of all, I won't
get into details but because of everything that's been said already tonight. That pretty much
cover some of the high points that needed to be addressed. I felt I had to say something about
the fuel tanks because that was key. Are there any other questions for me I'd take them now but
I can come back.
Mayor Furlong: Alright, very good. Thank you sir. Appreciate your comments. Anyone else
that would like to provide public comments on any aspects of this project? No? Seeing nobody,
okay. We do have a required public hearing with regard to the request to vacate the easements.
Kate Aanenson: That's correct.
Mayor Furlong: Okay. So unless there's anybody else that would like to provide comments
there, without objection we'll close that public hearing and continue on with the project. Let's
bring it back to council with regard to thoughts and comments or additional questions. Does
anybody have additional questions at this time?
Councilwoman Ernst: I do.
W'
City Council Meeting - January 26, 2009
Mayor Furlong: For city staff. Councilwoman Ernst.
Councilwoman Ernst: Paul how much do we have invested in the project as of today?
Paul Oehme: As of today? Oh I don't know. We have corrected the site for poor soils. We've
made a pad for the building to sit on right now. The site still has to be graded somewhat but
minimal cost there. There are some architectural fees associated with the pre -design. We're
about maybe 60% done with the site, or for what the building itself right now so. There's some
significant costs associated with that. But besides that.
Councilwoman Ernst: I mean is it, can you give me a rock number?
Paul Oehme: Oh um, it's in the hundreds of thousands because of the soil corrections.
Councilwoman Ernst: So if it's, and Tom brought up some good points. If we went back to re -
bond, could we, could we do that like after April?
Todd Gerhardt: My guess the call feature on our bonds are probably 6 to 8 years out and you can
do a refunding on that and depending on the interest rate difference that you would have and
basically you know you find a second party to buy these and hold them until the refunding comes
into place. It's something we're looking at now on the library you'll see in the next couple
months. So my guess the interest rate, what we got back in November and what we'd get today
would not justify it. I don't think you would have a savings enough to do it right now.
Councilwoman Ernst: Today but maybe potentially after April. Who knows?
Todd Gerhardt: Well we always look at our debt on a monthly basis, you know whatever the
market's doing. Ehler's, our bonding consultants and Greg keep a close eye on that and what the
interest rates are doing, and if there's any opportunities to do the refunding, a good example is
the library that we're going to bring back to you and do a refunding on that.
Councilman Litsey: Yeah, that can be done ... public safety facility that I'm familiar with figures
into it, but that can be done any time it looks favorable. I mean it shouldn't really affect the
timing of the project or anything because you can realize those savings at any point where it
becomes advantageous to do so. Once you, you know once the bonds have been.
Todd Gerhardt: Yeah, in the case of the library you won't see the true benefit until 2014 so.
Councilman Litsey: But I mean you could initiate that action at any time that it looks like it's
favorable to do so. So we could move ahead with the project and down the road if it seems the
prudent thing to do, we can still do that at the time.
Todd Gerhardt: Yep. Just like you would refinance your house at a lower interest rate. We do
the same thing and right now we're proposing back to you to look at that on the library.

City Council Meeting - January 26, 2009
Councilwoman Ernst: But in addition to that it sounds like they're going to be talking about
some things in the legislature where we might be able to get some additional state funding as
well.
Mayor Furlong: I'm not sure if Mr. Devine was saying there'd be additional state money or...
Todd Gerhardt: ...anybody any money.
Councilwoman Ernst: Either way, if it's even a reduction. I mean reduction of, maybe you
could clarify that for me.
Tom Devine: Me?
Councilwoman Ernst: Yeah. Because I know you're down at the State Capitol a lot.
Tom Devine: Well, you know right now the Governor has made a number of pronouncements.
In December, you know before the start of the new budgeting cycle that's taking place currently
in the legislature, and he put out some fairly clear edex relative to spending in terms of what's
going on, and of course he's announced what he could do and of course he did that first series of
cuts in December and those state aid funds that come out to the various cities, counties and what
not were trimmed back. Now, what's in store? It's very difficult to predict what the legislature's
going to do. My concern that I'm trying to express here today is we're undertaking a very
visible, expensive, glamorous project and I'm looking at that and saying at the same time we're
going to be fighting, I assume. Assuming that the State doesn't have new found income or
whatever between now and the close of the legislature, to make up the $5.2 billion, I mean over
the $5.2 billion is going to inflate by hundreds of billions between now and the close of the
legislature. So consequently what's the effect going to be? The effect to Chanhassen is going to
be fewer dollars are going to come down and there's going to be a fight between all the
municipalities about who's going to get what and what projects and what things and what
funding and you've already seen a lot of what's unfolding here. So my concern is the perception
is, well they can afford to build an $8 million dollar place to park snow plows, what are you
coming to us and complaining about we need, the State should be more generous in their state
formulas back down to us or the State funding for specific projects or whatever. That's what I'm
concerned about. We're talking about a time line that coincides with the close of the legislature
here in terms of what we're doing so, whether there's savings from the bonds or whether you can
go out and buy a new building, or an old building, and I do take this gentleman's comments
about time you remodel and do this and that and make it to what it is, maybe it's not but clearly
you can go out today and buy a building a lot cheaper than you could 6 months ago in the
commercial marketplace, you know and I don't know what's available in Chanhassen but all I'm
saying is I just bring up the perception. The 3 jets is the perception you know. It wasn't
necessarily all the reality but it's the perception that we've got to deal with and that's my
concern. And I do know that those funds are going to get cut. He's announced it. It's clear as a
bell that it's going to happen and that's the concern is that we're not penalized because we're
doing such a visible you know, maybe what would be considered by a lot of municipalities an
unnecessary project and they use that as a club against us. And I'm just trying to bring up the
51
City Council Meeting - January 26, 2009
political side of it because I think it's a reality. I don't think it's just a, you know slight
perception issue out there in terms of what goes on.
Councilwoman Ernst: So clearly it could have an impact on this project as well. No?
Todd Gerhardt: Mayor, council members if I can address Tom's statements. The City of
Chanhassen is one of many communities that does not receive local government aid. We get
zero. And the other aid that the State provides out is market value homestead credit. Last year
we were scheduled to get $160,000 in market value homestead credit. We got $90,000. So they
kept the second half payment of $70,000. For 2009 we were scheduled to get $120,000 in
market value homestead credit and we have not budgeted that money anywhere in our budget for
2009, 10 or 11.
Tom Devine: Okay. So you're saying that the income pack, the income, the impact of.
Todd Gerhardt: State aid.
Tom Devine: The impact of state funds coming back down into Carver County, that the city
won't.
Todd Gerhardt: Oh Carver County it will have an impact.
Mayor Furlong: Absolutely. That's a different story. We're talking about the City of
Chanhassen.
Todd Gerhardt: City of Chanhassen.
Tom Devine: Okay. Okay. It's the City of Chanhassen but I'm also looking taxpayer gets their
tax statement. What's the effect on their tax statement at the end of the day?
Mayor Furlong: And I guess to that.
Tom Devine: And I understand this is city and you know.
Mayor Furlong: No, that's fine but to that end with regard to the cost of funding this project,
both from a capital project as well as an operating project, we've discussed that both at a council
level to look ahead and what that would be. As well as the timing of this project is, as Mr.
Gerhardt said earlier, this has been discussed for a number of years. We haven't been putting
together drawings and everything for that entire time because we chose to wait until from a
funding standpoint we had availability within our tax levy to do this in a manner that would not
increase property taxes. So we are not, as our debts or our bonds come due at different times.
Some are refinanced. Some are not. This is being timed now in large part because of funding
capacity within our city's own ability to fund it. Okay. It's not dependent upon state aid. As
Mr. Gerhardt said we haven't budgeted it going forward. In fact the last 6 years we have not
budgeted in our general fund any funds coming from the state. We put any fund that is received
we put into our street and road project fund and that goes to offset the taxpayer's side of costs for
01
City Council Meeting - January 26, 2009
some of the projects, the street mill and overlays and reconstruction projects that we've done and
that we discussed earlier this evening so we certainly, if the money is distributed from St. Paul,
we certainly take it and put it to use in the city through streets but we don't, there are no staff
salaries. There are no general operating services associated with that funding. To the extent that
I think, and we can get into that in a little bit but I think clearly from a timing standpoint,
modesty aside, I think there would be, the state would like to see a number of cities run the way
we have run Chanhassen. We don't depend on outside sources. Now we have opportunities that
other cities don't have, and so I don't want to say that everybody should do it our way but we
found a way to do it with, to plan long term for projects such as this and to time the, to look at
the timing of the projects such that we're not doing everything all at once that needs to be done,
but looking at it methodically and logically and strategically on when these projects are
considered, and that's been part of why you know, if initially when this was brought up, if we
were just going to do the project without regard to the financial aspect and effect on the city's
financial position and taxes, we would have been having this discussion 3, 4, 5 years ago. Okay
because the need has been there. I think the other thing that hasn't come up with regard to need
is currently our current facility is about 25, 26, 27,000 square feet?
Paul Oehme: 24.
Mayor Furlong: 24. He corrects too. And just about... And I'm just going to ask the question,
what's the size of this facility?
Paul Oehme: 82.
Mayor Furlong: 82.
Todd Gerhardt: Now you're getting it mayor.
Paul Oehme: About.
Mayor Furlong: The big question is, is how long will this facility last the city's needs since we
are not fully built out. We are about 60% all the way developed. Once development occurs we
are going to continue to develop, and I think we're going to get more than our fair share from a
rate standpoint but how long will this facility meet our needs?
Paul Oehme: I mean the building that we're putting before you tonight is the, should last the
entire length of, until we're fully built out. I mean we have a little bit of capacity in this building
for future expansion. We programmed that in. Into this facility. Not much but enough where
we think we can get by out into the future until we're built out.
Mayor Furlong: The bottom line is we're looking at a building tonight that is going to provide
the needs of the city, even to the point in time when we are fully developed, and that was a
question that came up. At some point we'll have to put another addition on, right? And that's
why the site probably wouldn't handle another addition, but we don't need to because we're not
building just what we need today and leaving for future council and residents to look at what
they need. Why are we doing that? My opinion, I think it's more economical to do it today.
47
City Council Meeting - January 26, 2009
Anytime I've been involved in a project where you plan for an addition and you're going to save
money on that. You end up never saying money, and you never you know. And I think we've
all been there and seen that so I think that's the other thing we haven't talked about this evening.
This is, this is a facility that is intended to support the city's needs even after 20, 30, when we are
fully built out. So I think that's all part of it.
Todd Gerhardt: Very similar concept that we did for the library. The library is built for the
city's ultimate build -out. So it's 35,000 square feet when we have an ultimate population of
about 35,000 so.
Mayor Furlong: Okay, thank you. Councilwoman Ernst, other questions?
Councilwoman Ernst: The last question is if you could just tell what the impact would be if we
delayed the project? What would, I mean I know we have the costs out there but that doesn't
mean that we've lost that money. It just means that it would be on hold.
Todd Gerhardt: Well, some of it's a legal question. And then on the bonds it would be an
arbitrage question that we sold bonds and earned interest without spending that down based on
federal IRS guidelines so there would be a penalty for not doing that. If it's more than I think 9
months or something like that.
Councilwoman Ernst: And so the legal part of it is?
Todd Gerhardt: The legal part is that we've entered into contracts with the construction manager
and architect and I don't know what the language in those two agreements call for. I'm sure
there's parts in there where we could probably stop the project. So we'd need some contractual
obligations there that we'd have to look at.
Councilwoman Ernst: What's that? Roger, what'd you say?
Roger Knutson: I was just saying you'd be paying interest on your bond debt. That's not a legal
issue I guess. It's a financial issue. Until you reach your call period or equivalent.
Todd Gerhardt: Well we'll be making a principal payment in 2010 so there'll be a $900,000
payment in 2010. But we have money for that.
Councilwoman Ernst: So it concerns me that we're this far into the project and now we're
coming back and asking for a variance.
Todd Gerhardt: We grant variances almost all the time.
Councilwoman Ernst: Well we deny a lot of variances too.
Todd Gerhardt: Yeah.
Mayor Furlong: Other questions? Comments
EPI
City Council Meeting - January 26, 2009
Councilman Litsey: Well I hope people understand a lot of due diligence was put into this
project. I mean we've been looking at this for quite some time. All these questions have been
asked. I mean we looked at options. We looked at existing facilities. We looked at the current
facility and what we might do there. And it came down to this was the best approach. The city's
positioned itself financially to handle this project, as Mayor Furlong has very well laid out for
the audience tonight and I look at this as an essential service that we provide the city you know.
Keeping the streets plowed and public works is a real critical element of what we provide for the
residents and the businesses in this community and there's no doubt the needs been there for
quite some time but we have waited until financially we could do this. Fit it in within our current
projections and so forth financially and so I think it's a needed project. It's a well thought out
project. I commend everyone that's been part of it to make this work. I'm concerned a little bit
about the wetland implications but I think it's been well pointed out that if this was a commercial
development the impact would be considerably more perhaps and I think caution has been taken.
It's on the radar screen moving forward that that's a sensitive part. I mean I'm very much into
the wetland buffer zones and so forth. I've had issues with that before but I think that in this
situation, given the need and the thought that's gone into it and the overall impact on this parcel
of property is quite less than the commercial development would be potentially and that we
realize that that's a sensitive thing we have to pay attention to. I think it's been well covered and
I think we need to move forward with this. It's again I don't want people to get the impression
this is just something we just kind of just, we're just thinking through some of these items now.
All the questions that have been raised, all the things that we've talked about, we've talked about
in great depth in work sessions and I don't think now's the time to go back. We've moved
forward. We've done our due diligence and I think we need to continue.
Mayor Furlong: Thank you. Other comments? Councilwoman Ernst.
Councilwoman Ernst: I'm really struggling with this. We need this facility. I have no doubt in
my mind that we need this facility. I have some major concerns about the environment with the
location of where the chemicals are and where these fuel tanks are, and thank you for giving me
the, or giving the information that you did. I still have some concerns with the chemicals
because they're actually much closer to the creek than the fuel tanks are. Where the salt and the
chemicals are.
Todd Gerhardt: It's just salt.
Councilwoman Ernst: It's just salt?
Todd Gerhardt: No chemicals. Salt and sand.
Councilwoman Ernst: And I'm feeling like okay, we're coming back with this variance tonight
and I'm feeling like I'm forced into making this financial decision and I don't want to feel that
way so I'm wondering if there's another, another option here as to how, I don't know if there is
or not, in where those are placed.
49
City Council Meeting - January 26, 2009
Todd Gerhardt: Mayor, council members if I can just maybe get you to feel a little bit more
comfortable about the salt. It's the salt we put on the roads and once we put it on the roads and it
melts, it doesn't disappear. It goes into the storm water ponds. It goes into our creeks you know.
It's part of Minnesota. This is something we have to do and to maintain our roads. In the
parking lot there's an environmental manhole so some of the heavy stuff that may come from
break pads will settle out there and then we will clean that out before it even goes into the series
of ponds. Before it goes into Lake Susan. So the chemicals for the anti -freeze and that are all
self contained inside the building and as Paul mentioned most of the car washing, the grease and
the things from the vehicles will go into the sanitary sewer system and be treated at the sanitary
sewer plant. So any spills that occur inside the building, same thing there.
Councilwoman Ernst: And the other piece to it is, I don't have a clear picture of the whole
financial impact if we did delay this for a while. And because I don't have those questions
answered, I mean I want to support the project but I can't support the project based on what I
know today.
Councilman Litsey: I guess my frustration is that we've been down this road. We spent a lot of
time on this. We've looked at all the different options and this seemed the most reasonable. The
most prudent. They're doing their best to fit it on this parcel of property. A lot of this is going to
be preserved the way it is. To push it back, well we're going to take out trees. I mean you've
got to balance that out and this seems to be the best balance but I mean we've talked about all the
issues. The options and best place to put it and the square footage and the architecture and all
those things. We've been down that mad for months. To stall it now, I don't see what the
rationale is.
Councilwoman Ernst: Like I said before, when we were looking at this before I was not, I did
not see how that was in relationship to where the creek is. I saw that, I saw where it was placed
but I didn't see that, there was not that relationship there.
Councilman Litsey: Well that might be but the creek hasn't moved and this has all been talked
about and so. I mean I'm trying to respect your viewpoint but I just, I'm frustrated because
we've looked at this. We spent so many hours on it and it just.
Mayor Furlong: Okay. Councilman McDonald, your thoughts.
Councilman McDonald: Well I guess I have to share Councilman Litsey's frustration because
we have been over this for over a year. I am perfectly fine if it comes down to we don't want to
go into the buffers. Fine. Then we move it up and over and we take care of the problem but at
that point we are going to take out significant trees and we will begin to infringe upon the music
studio above us. I think that you know we have granted these types of variances before. G.E.
Osmotics comes to mind where we went in and we granted a variance within the buffer zone at
that point because of what they wanted to do. This is not something new and this is not
something new within this particular area. Again it is salt. It's going to get into the lakes
anyway because as Mr. Gerhardt said, it goes on the roads. It melts. It goes into the water
system. There's nothing we can do about that unless we get rid of using salt on roads. The other
cl
City Council Meeting - January 26, 2009
thing you need to look at is that if we delay this, right now a snowplow, how much does a
snowplow cost?
Paul Oehme: About $180,0004190,000.
Councilman McDonald: We currently have assets of over a hundred thousand dollars just sitting
outside because we can't fit them into a building. If you want to look at costs and what this is
costing us, the deterioration of those assets will far exceed anything we do as far as delaying this
project to re -bond it. Again we have looked at it for over a year. We have been through this.
And again Chanhassen, as the mayor says, we are not dependent upon the State to do this so
we're not going to get the look back and see that we're wasting the State's money because we're
not wasting the State's money. So I think that you know based upon this, I am perfectly fine
with going forward. If the problem is the setbacks and if the council feels that we need to do
something about that, I don't see where that needs to delay anything. It's just start planning
which trees we're going to cut down because it will fit upon the property with or without the
variance and I guess the question is, do you want the trees there or do you want the variance. So
I'm in full support of this project and I'm ready to go forward on it.
Mayor Furlong: Okay, thank you. I think there have been some questions raised this evening.
This has been a project that has been, that we've been discussing for a long time. We've looked
at a variety of options and we continue to each step along the way peel back the onion a little bit
more if you will in terms of some of the details. The site plan. Clearly the timing of this is
appropriate when you actually, just like a private developer would, take a look at whether or not
it's your best alternative and I think in terms of where the alternatives are, whether to buy and
remodel or build new, that's always a decision that any property owner would go through. We
looked at buying existing and completely remodeling. We looked at buying next, for the
property right next to our existing facility and having a two building campus if you will. We
looked at a number of the buildings that have been mentioned this evening as well as others, and
in all the cases the, it came back to this was the most financially prudent and operationally best
way to do what we're trying to do, and I think that's what we're always trying to do. There are
more details. I think we're all concerned about impacts to wetlands and the creeks that run
through our city and from lake to lake. Clearly that's the case here. This entire industrial park
has I would guess, though I wasn't on the council at the time, had issues with the creek flowing
through the area. The creek doesn't start and stop at the borders here. It's throughout the area
and I'm sure that there have been issues addressed. In this particular case what gives me comfort
is that with this project we're actually improving the storm water management on the site.
Currently the water just runs off into the creek. There's debris there. Runs into the wetland.
That all will be redirected and contained through a management system to reduce the rate at
which the storm water enters the natural storm water system called our creeks and lakes. It will
increase the quality of that. As we heard earlier tonight there's actually a series of ponds that
the water will eventually flow through, including the last pond at Lake Susan which was just
upgraded a few years ago, before it even enters into Lake Susan. So I am comfortable looking at
this. I think the, you know it's always a balance and I look at these and try to say are we finding
a fair balance between competing interests. The first interest is don't affect any of the natural
resources, whether they're trees or water bodies or wetlands and yet at the same time provide a
reasonable use. If this was a private developer coming to this site, as we heard earlier this
51
City Council Meeting - January 26, 2009
evening there would likely be greater intensity, as well as requests for some setbacks. Just in
terms of the access to the property and almost naturally is going to require one. So I think these
have come out in conversations. We kind of continue to move along as any private business
owner would in looking at the site of where to locate. How to locate. How can we fit it on the
best given what we have there. All these parameters. Chanhassen is not flat prairie. It is always
rolls or creeks. That's what gives it the natural features that we all love, and so what we do is we
have to do our best to protect those and I think this does it. In terms of the timing, the objective
here is to go forward with the site plan and then we'll proceed and next time we see this we'll
have bids for most of the major items and at that time we'll have again better information from a
timing standpoint as well as what the actual costs are. We'll be in a better position to do that.
And so I am comfortable going forward with this plan because I believe that it provides a fair
balance with a reasonable use of this property based upon zoning as well taking into account the
natural features of the site as well. We've tried to do this in a way that is both cost effective,
fiscally responsible, as well as looking at the operational needs of the city and I think we're
finding that we're going to be able to accomplish those goals. So all told I think we should move
forward this evening on this project and continue to look at ways to save money. Make sure that
we get this project in on budget or lower. If there's opportunities out there through bidding out
the contract or running it through a contract manager system, as we're doing it, to save money
long term, short term, we need to look at those. But we always need to look at what those
options are and balance out the benefits against the costs so. So I'm comfortable going forward
this evening. We can spend more time moving it around on the site but I don't know that we're
going to gain any value from that in that whatever the variances are here, they're being mitigated
I believe by better storm water management across the entire site. So I think we should move
forward this evening with what we have and with the information we have before us. I think
we're comfortable moving forward. Any other thoughts or comments? If not we have a motion
before us. Two motions, correct?
Kate Aanenson: Yes. The first motion is regarding the vacation of the utility easement.
Mayor Furlong: And is that, is that the modified motion on page I of the staff report? Or is that,
where is that motion on the.
Todd Gerhardt: On the cover pages of each one.
Mayor Furlong: The very beginning, proposed motion A, B and the adoption of the facts?
Kate Aanenson: Yeah, that would be for the site plan and the conditional use.
Mayor Furlong: And the variances and conditions.
Kate Aanenson: The staff report before that on A would be adopt.
Mayor Furlong: So first page, proposed motions. Any other thoughts or comments or would
somebody like to propose a motion?
52
City Council Meeting - January 26, 2009
Councilman McDonald: I'll propose the motion. I'll do it. I make a motion that the City
Council approves a resolution vacating the drainage and utility easements located on Lot 5 and
Lot 6 of Chanhassen Lakes Business Park 5`h Addition.
Councilman Litsey: Second.
Mayor Furlong: Is that the entire motion?
Kate Aanenson: That's for the first one.
Councilman McDonald: That's Part A.
Kate Aanenson: That's A.
Mayor Furlong: Okay.
Councilman McDonald: Do you want to do these separate or?
Todd Gerhardt: You can do it all as one or separate.
Mayor Furlong: We can do it all as one unless there's any objection.
Councilman Litsey: I'll withdraw my second then.
Mayor Furlong: Okay. Go ahead Mr. McDonald.
Councilman McDonald: Okay. I also propose that the Chanhassen City Council approve a Site
Plan for an 82,500 square foot one story office warehouse building with a mezzanine storage
area and setback variances from the creek and wetland for the parking lot areas, plans prepared
by Oertel Architects and the City of Chanhassen dated December 5, 2008, subject to conditions
through 24 of the staff report. Also that the Chanhassen City Council approves a Conditional
Use Permit for the outdoor storage subject to condition 1 of the staff report and adoption of the
attached Planning Commission Findings of Fact.
Mayor Furlong: Thank you. Is there a second?
Councilman Litsey: I'll second that.
Mayor Furlong: And just to clarify, I was looking at the first item that dealt with the wetland
variances, correct?
Kate Aanenson: Yes.
Mayor Furlong: Mr. McDonald, correct?
Councilman McDonald: Part A. Part A, we've got them all
53
City Council Meeting - January 26, 2009
Kate Aanenson: We included them all, including variances.
Mayor Furlong: Thank you for clarifying. So I've got a motion made and seconded. Any

CHANHASSEN PLANNING COMMISSION
REGULAR MEETING
JANUARY 6, 2009
Chairman Papke called the meeting to order at 7:00 p.m.
MEMBERS PRESENT: Kurt Papke, Debbie Larson, Mark Undestad, and Denny
Laufenburger
MEMBERS ABSENT: Kevin Dillon, Dan Keefe, and Kathleen Thomas
STAFF PRESENT: Kate Aanenson, Community Development Director; Bob Generous, Senior
Planner; Paul Oehme, City Engineer/Public Works Director; Alyson Fauske, Assistant City
Engineer; and Terry Jeffery, Water Resources Coordinator
PUBLIC HEARING:
_PUBLIC WORKS FACILITY: REOUEST FOR A SITE PLAN REVIEW WITH
VARIANCES AND A CONDITIONAL USE PERMIT FOR AN 82,500 SQUARE FOOT
PUBLIC WORKS BUILDING ON PROPERTY ZONED INDUSTRIAL OFFICE PARK
CHANHASSEN, PLANNING CASE 08-25.
Bob Generous presented the staff report on this item.
Papke: Alright, Debbie.
Larson: The only question I have, and I think it's probably self explanatory based on what
you've told me but on the landscaping on page 7, we're showing that there's a required 70 trees.
We're proposing to put up 22. Is that because there's a lot of natural stuff already up there? A
lot of trees that we're just not touching.
Generous: Correct.
Larson: So we don't need to do that.
Aanenson: Yeah, I think it was hard to tell from the picture. The original one that we showed,
maybe you can go to that one first. The first picture shows the entire site. The two parcels that
were included in the site. The project itself is sitting to the interior so those are all the trees that
we're preserving, and that kind of goes into that first why we looked at the variances. Trying to
preserve those trees and create that buffer on Audubon itself, so that's part of that tree
preservation there and those trees are counted towards that, so not all of that's being disturbed.
Larson: Okay. That's all I have.
Generous: Or very little.
{CANNED
Planning Commission - January 6, 2009
Aanenson: Very little of it, correct. Yeah, provides that, so when you're driving down Audubon
you don't see that. Whereas now when you go by the public works building, some of that is very
visible. That was one of the goals that we tried to accomplish too. And then when we get a
chance the architect, there's a lot of interesting energy applications that are being used in this
building and site design that the architect's here to talk a little bit about too and I think that plays
into some of the features that we were looking at too. The lighting. The roof tops. Some of
those things so when we get to that portion I'll let him speak a little bit more about the
uniqueness of the building.
Laufenburger: Good job Bob and staff. Just a couple questions. This is a new facility. Is this
providing the consolidation of public works facilities in various stages around the city or, can
somebody speak to that?
Aanenson: Yeah, maybe let the City Engineer address that question.
Oehme: Thank you Chair, commission members. Yeah, that does, the new facility does
consolidate a lot of equipment into this one facility. That's one of our problems we have right
now is we have material and equipment spread all throughout the city and parks. We have a
bunch of materials, our equipment stored in water towers and other areas around town. It's just
hard to properly maintain and keep track of a lot of that. A lot of those equipment ... so that's
what a lot of cities have been going to is trying to consolidate. Try to keep a lot of this
equipment under one roof so it's really more accessible and usable.
Laufenburger: And will this facility be the only public works facility for the city of Chanhassen?
Oehme: Yes. It will be the only facility. So our existing facility that we're currently using.
Laufenburger: Right.
Oehme: Actually we're working that facility right now.
Laufenburger: Okay, so that will be vacated and this will occupy.
Oehme: Yep. We're definitely going to try to sell that.
Laufenburger: And I don't recall seeing this. What are your plans for when, assuming all the
approvals are received, when do you anticipate occupancy of this?
Oehme: Well we're anticipating the first half of 2010. January -February timeframe.
Laufenburger: So about a year.
Oehme: Year plus.
Planning Commission - January 6, 2009
Laufenburger: Thank you. And then one other question. I think you asked it regarding the
meandering creek. Is that Riley Creek that is to the east?
Generous: Yes.
Laufenburger: Is that correct? Do you have any evidence that that meandering will change in
high water times or anything?
Jeffery: If I may Chair Papke, Commissioner Laufenburger. The creek itself, I mean you've got
to remember, this area where the public works facility is being proposed has been used as what's
called the bone yard for city staff and it was used prior to any of our shoreland rules going into
effect so, so the long way getting to answer your question, there has been considerable
degradation along the top bank area within the channel itself.
Laufenburger: That would be just to the west of the channel of Riley Creek, right?
Jeffery: Correct. Resulting in conditions that are prone to erosion throughout there, so I think as
part of the restoration within that area, part of the mitigation, the stabilization outlet channel will
be a priority concern within there. Any natural channel will change it's course over time and
there's nothing we can do to stop that entirely, but areas where you know the actions that we've
got or water that's being discharged where it's creating what I'll say hazardous conditions, for
lack of a better word, we can act to mitigate those to minimize the chances of that channel
changing course.
Laufenburger: Okay.
Jeffery: And I also think it's important to note, a lot of the storm water features that are being
put on the site will actually improve the hydraulics of that area and lessen the opportunity for
erosion within that channel. Everything from the establishment of the vegetation along that
shoreline, where now in many cases vegetation is absent to the treatment and detention of storm
water behind the building taking the roof runoff behind the building. Bringing it to the wetland
and then taking everything from the drive on the south side of the building and bringing it to
what will amount to an engineered wetland. You're actually putting it into the wetland and then
the parking area will actually be diverted to a pond that was constructed when this entire
development went in in ' 85-86 to the east. So that should actually help mitigate any problems
within that channel.
Laufenburger: That's the pond that you're referring to right there.
Jeffery: Yes, thank you.
Laufenburger: Thank you. That answered my question.
Undestad: Just one quick one too. On, can you bring that slide up that had the shaded areas of
where the impacts are. Yeah. The question on there was just going around that tree with the
driveway, we're not, the shaded areas is inside of the setback buffer area, is that right? It's not
Planning Commission - January 6, 2009
that. So the shaded area's actually within the setback buffer area, not the actual wetland in
there?
Aanenson: That's correct.
Undestad: Okay.
Papke: Okay, just a couple here. The oak tree that we're going to great lengths to save. Quite
often in the construction set like this, despite our best efforts, sometimes these things don't work.
The City Forester, what's the assessment of the probability of that oak tree actually surviving?
Generous: She was very positive. They're doing everything that we require for people to
mitigate and protect it. Before they go forward they're putting up the tree protection fencing.
They're using a retaining wall so they don't change the elevation at the drip line so her prognosis
is good as long as it's followed through.
Papke: I'd hate to go through all that effort and then end up with a big pile of firewood. Will
there be salt storage facility? One of the things that kind of strikes me is if we're storing salt
here with the possibility of runoff from a pile of salt and then we're also, you know encroaching
into the Riley Creek watershed. I'm having kind of difficulty coming to grips with those two.
They seem to be kind of fighting each other. Can you speak to that at all? You mentioned we're
going to extra efforts to mitigate any storm water nmoff. Have we taken the salt, I assume we've
taken the salt storage into account but I'd just like to make sure we vocalize that.
Jeffery: Yeah, Chairman Papke, yes we have. hi fact it was a large discussion that we had at
that point to make sure that wasn't going to produce runoff into the creek itself. First of all the
salt container, and Mr. Oehme correct me if I'm wrong but the salt containment area itself will
be of solid construction, which in itself will reduce the leeching out of that area. And then
drainage within the parking area will actually be connected to the storm sewer system which
divert the water to the pond and away from the creek so it should not pose a hazard to the, to
Riley Creek itself. Or the wetland to the south.
Aanenson: Just to be clear, there is a current structure on the existing public works building,
enclosure, that you can see and that same structure will be moved but again measures will be
taken. Actually we did have a discussion about where the best location was. It has been moved
to accommodate that concern so it was moved a couple places to find the best spot to mitigate
that. The staff had the same concern internally.
Papke: Okay. Applicant presentation. Hear from the architect or.
Jeff Oertel: Good evening Mr. Chair, commission members. For the record my name is Jeff
Oertel and I reside and work out of St. Paul. It's a pleasure to be here tonight. A few comments
first of all to add onto the salt storage. The orientation of that storage building is pretty much
ideal in relative terms with these buildings you basically have an open end almost all the time
and then you have three enclosed sides and the structure is oriented, if I recall, south, southeast
and it avoids a lot of the winter, you know those strong winter winds and that sort of thing. And
4
Planning Commission - January 6, 2009
we will do what we can to I think even out, level or even dip the inside of this structure so that
any watery, salt, whatever is contained in that and not run off. I don't know if we have, or if we
can throw a few pictures up on the wall. Just to orient you a little bit more within the building.
Alright I'll start on the outside of the building. This, I apologize. This shot's pretty hard to see.
There's a lot of detail. One thing that wasn't mentioned is that even though this facility's for all
of public works operations, there is a community component to this that the entry that you see in
the illustration there is also the public entry. The main public entry and it's anticipated that this
building will be used for voting purposes, and internally the facility was designed for the
stacking of people to come in. Move through what is the multi -purpose lunch room, training
room and that's the room with the little set of it looks like about 16 tables and chairs. So even
though that will be where the public works staff get training. Have their meals and breaks, that
area will be used for the public perhaps for more than just voting purposes, but certainly for that
in particular, and we do have a waiting area. A fairly large waiting area just off the main entry
for that purpose as well. Otherwise, within the building I know your main focus is on the
exterior but within the building we have offices which would be at the bottom of the sheet that
we're looking at, which looked to the west. And then internally within that office sector of the
building, we have the typical restrooms and locker rooms and support areas of the building.
Now that whole comer which will be the most visible part of the building has the more
expensive material. It has the brick and it has quite a lot of glass for viewing. But within the rest
of the building what we're doing with day lighting is trying to get day lighting from up above
and you can see off to the right in this shot, where the vehicle maintenance area is, there's a clear
story unit and we've actually, in our facilities, designed quite a few buildings like this where
there's a clear story right at the roof edge and daylight just seems to love to follow that ceiling
pattern, and it works very well for bringing in daylight. And we're also adding quite a bit of
clear story glass at the office area to bring in daylight within that area. And partly because we're
trying to walk a fine line between the budget that the city has and not exceeding that budget,
we've come up with an idea to bring in daylight within that big vehicle area. That big bay that
you saw on the plans. And since it's counter productive to put in a lot of glass at the knee level
or at the viewing level, because that's where all the vehicles are stored and equipment put up
against the wall. We're adding the glass units up high to bring in the daylight up high at a more
modest cost. Otherwise as mentioned earlier, we have quite a few devices within the building
and systems to try to conserve energy. These buildings do use a lot of energy because the
exhaust gases have to be removed from the building, both for health reasons, for code reasons,
and so we're adding quite a bit of mechanical, special mechanical systems to try to lower energy.
We're looking into geothermal heat which I believe will be considered as an alternate for the
council to consider, depending on how the price comes in. And we're looking at quite a few
lighting devices and sensors to avoid lights being turned on and staying on all day and so there
are quite a few systems within the building to help keep the energy costs down. Just a few last
notes. On the exterior we're going with a fairly, what would be an inexpensive pre -cast wall
panel. I'm sure the commissioners are familiar with that, but rather than going with the typical
no-brainer panel, we are trying to break up the skin of it with some horizontal pieces randomly
placed to try to break up the wall, because it is a sizable wall. Fortunate in our favor, as a part of
the planning, the big, long, what did we say it was 300 some foot wall, long wall will be facing
the woods and almost not visible to the public whatsoever. That was a brief visit through it and
if you have any questions I'd be happy to answer.

Planning Commission - January 6, 2009
Larson: I was just wondering, can you show us where, it's hard to see within these pictures
where this building is going to be for the salt.
Jeff Oertel: Sure. It's on the.
Larson: It looks like it's removed or over somewhere else.
Generous: On the north side.
Jeff Oertel: It's dashed in. There's the salt.
Oehme: By the northeast comer.
Jeff Oertel: And it's not the prettiest of structures of course. It's got a kind of a hoop top to it
and a concrete base and the open end is facing oh, it's facing southeast but there you go. Thank
you. And so one of the dilemmas that we have, my firm has designed I don't know, 20 or 25 of
these buildings but the dilemma is that we as the community need salt on the roads and the
municipalities need to buy it in bulk. And even right now, I don't know if Paul's had this
experience but some operations are being cut off and if they haven't pre -ordered a fairly large
quantity over that tough period at the end of the year, some communities are running out of salt
and had to just pick up small batches so the salt buildings tend to want to be big because of the
need to buy in bulk and it's just that unfortunate, tough component. It's never the prettiest of
structures.
Larson: I don't care if it's pretty or not.
Jeff Oertel: I do.
Laufenburger: If there's anybody concerned about pretty...
Larson: Touch& That's all.
Papke: Thank you very much. Any other presentation from the City? Any other issues? Okay.
With that I'll open the public hearing. If anybody from the public would like to get up and make
any comments on this matter before us, please step up to the podium and let us know what you
think. No movement. With that, I close the public hearing and bring it back to the
commissioners for discussion and debate and Mark we'll start with you then.
Undestad: I didn't really have any issues, no. I mean the size of the site and the coverage
they're on there, we know we don't have a hard surface coverage problem there. And the way
things lay out here, you're going around all the, saving all the trees and things. I think it was
well thought out. It looks nice.
Laufenburger: I concur. I, just visually I like the building. It's kind of hidden. People who
want to see what good architecture is in place in Chanhassen. We might have to put up green
signs that says you know public works facility here. No, I think it's, I like it.

Planning Commission - January 6, 2009
Larson: Yeah, I like it too. No issues.
Papke: Okay. I had some issues coming into the meeting. You know I'm always nervous when
the city asks for variances and then doesn't necessarily grant them to the public but I think we've
shown good justification for this one and I think all the concerns I had have been... So with that
I'll entertain a motion.
Laufenburger: Mr. Chair. The Chanhassen Planning Commission recommends that City
Council approve the Site Plan for Planning Case #08-25 for an 82,500 square foot, one story
office/warehouse building with a mezzanine storage area with a Conditional Use Permit for
outdoor storage and setback variances from the creek and wetland for the parking lot area, plans
prepared by Oertel Architects and the City of Chanhassen dated December 5, 2008, subject to the
conditions of the staff report and findings.
Papke: Is there a second?
Larson: I'll second that.
Laufenburger moved, Larson seconded that the Planning Commission recommends the
City Council approve the Site Plan for Planning Case #08-25 for an 82,500 square foot, one
story officetwarehouse building with a mezzanine storage area with a Conditional Use
Permit for outdoor storage and setback variances from the creek and wetland for the
parking lot area, plans prepared by Oertel Architects and the City of Chanhassen dated
December 5, 2008, subject to the following conditions:
1. The developer shall provide exterior benches and/or tables.
2. Signage shall require a separate sign permit review to determine compliance with City
ordinance.
3. The applicant shall mitigate for the lost functions and values of any buffer variance by replacing
an equivalent area of buffer in a location which will provide the maximum water quality benefit.
Preliminary review indicates that area to be northeast of the wetland.
4. The applicant shall restore the stream channel as well as the top of bank and flood plain for
Riley Creek including the removal of any construction and other debris in the area.
5. The applicant shall prepare a vegetation management plan for Riley Creek. This
management plan shall be created in conjunction with the landscaping plan and the
Environmental Resources Specialist and Water Resources Coordinator should be consulted in
the creation of this plan.
6. The applicant will modify the existing NPDES permit to identify the construction manager
for the project.
Planning Commission - January 6, 2009
7. The applicant will provide adequate treatment for drainage directed to the wetland.
8. The applicant should look for ways to promote infiltration and incorporate alternative
stormwater management best management practices into the site design and build. One such
measure is the construction of a bio-infiltration feature at the outlet from the drive aisle
northeast of the wetland. Other features to investigate include pervious pavement systems,
cisterns, biofiltration trenches, preservation or re-establishment of vegetation, etc.
9. The final 200 feet of the swale located west of the proposed facility needs to be protected
with Category 2, Wood Fiber IS Erosion Control Blanket.
10. Those areas to be planted in BWSR seed mix U7 should be seeded at a rate of 15LBS
PLS/acre where PLS means "Pure Live Seed".
11. The buildings are required to have automatic fire extinguishing systems.
12. Building plans must be prepared and signed by design professionals licensed in the State of
Minnesota.
13. Retaining walls over four feet high must be designed by a professional engineer and a permit
must be obtained prior to construction.
14. The 51-inch and 45-inch oaks located near the northwest and southeast corners of the
building shall be protected by fencing throughout construction.
15. The site plan must show the dimensions of the lots.
16. The northern access must be revised so that the maximum width does not exceed 36 feet.
17. An encroachment agreement is required for the portion of the parking area that lies within the
public right-of-way.
18. If feasible, the runoff from the cold storage area access should be conveyed to the existing
storm sewer.
19. Revised drainage calculations and storm sewer sizing must be submitted to ensure that the
existing downstream infrastructure can accommodate the proposed runoff.
20. An encroachment agreement is required to construct the northern retaining wall within the
drainage and utility easement.
21. The proposed top and bottom of wall elevations must be shown.
22. The drainage and utility easement over the abandoned portion of the sanitary sewer must be
vacated.
Planning Commission - January 6, 2009
23. The existing drainage and utility easements and abandoned utilities must be labeled on the
plan sheet.
24. The utility plan must include a note regarding the connection to the existing storm sewer."
All voted in favor and the motion carried unanimously with a vote of 4 to 0.
Laufenburger moved, Larson seconded that the Planning Commission recommends that
the City Council approves a conditional use permit for outdoor storage, subject to the
following condition:

the variance?
Auseth: The deck and the shed are as is when we went out there.
Laufenburger: Thank you staff. Could you just go into a little further explanation about the 30%
coverage removal and why, if they chose to remove a tree, that would be in violation. Can you
just explain that a little bit more for me please.
Justification
• Reduced variance need to minimum
• Because of the nature of the facility, vehicle size, outdoor storage, etc, need large space.
o Turning radius of tandem axle vehicles
o Storage of salt, pea rock, mulch, trailers
• Desire to save as much of the woodland area to the west as possible
• Desire to save 45 inch oak southeast of building
• Avoidance of the wetland
Mitigation
• Currently from the top of bank for Riley creek west is either denuded of vegetation or
dominated by invasive plant species
• Currently the channel and the area immediately adjacent to the channel has a substantial
amount of construction debris
o The plan will involve cleaning all debris away from within the channel and between the
proposed back of curb and top of bank.
o This area will be planted with native trees, shrubs, forbs and grasses — a detailed
vegetation management plan will be created
o Areas of scour which have developed in the channel will be stabilized.
• The buffer will be expanded both northeast and northwest of the wetland so that total buffer
will be far greater than what is required under City code.
• Much of the buffer is dominated by reed canary grass - an invasive species. This will be replaced
by a special BWSR seed mix.
• An engineered wetland will be created northeast of the wetland to treat runoff from the
driveway prior to entering the wetland.
• A bio-filtration swale will be created west of the building to treat roof runoff prior to entering
the wetland.

PROPOSED MOTION
A. "The Chanhassen City Council approves a Site Plan for an 82,500 square -
foot, one-story office/warehouse building with a mezzanine storage area and
setback Variances from the creek and wetland for the parking lot area, plans
prepared by Oertel Architects and the City of Chanhassen, dated 12/05/08,
subject to conditions 1— 24 of the staff report.
B. "The Chanhassen City Council approves a Conditional Use Permit for
outdoor storage, subject to condition 1 of the staff report."
And,
Adoption of the attached Planning Commission Findings of Fact.
City Council approval requires a majority vote of City Council present.
EXECUTIVE SUMMARY
The City's Public Works Department is requesting site plan approval for an 82,500
square -foot public works building with a conditional use permit for outdoor storage
areas. The variance requests are to permit the parking lot to be closer to the wetland
and the creek than is permitted by ordinance. In developing the plan for the site, the
City did investigate several site plan configurations for the project. The site plan
configuration being reviewed includes the minimum variance request while
providing for the needs of the public works operation.
While the ordinance specified 70 trees for the parking lot, the City is preserving
the large wooded area to the west of the building. In the past, staff has allowed
the clustering of required plantings on site to meet ordinance requirements.
Therefore, staff has determined that the approximately 5 acres of preserved
woodlands west of the building satisfies the City requirements for landscaping.

LEVEL OF CITY DISCRETION IN DECISION -MAKING:
The City's discretion in approving or denying a site plan is limited to whether or not the
proposed project complies with Zoning Ordinance requirements. If it meets these standards, the
City must then approve the site plan. This is a quasi-judicial decision.
The City's discretion in approving or denying a variance is limited to whether or not the
proposed project meets the standards in the Zoning Ordinance for a variance. The City has a
relatively high level of discretion with a variance because the applicant is seeking a deviation
from established standards. This is a quasi-judicial decision.
The City has limited discretion in approving or denying conditional use permits, based on
whether or not the proposal meets the conditional use permit standards outlined in the Zoning
Ordinance. If the City finds that all the applicable conditional use permit standards are met, the
permit must be approved. This is a quasi-judicial decision.

PROPOSAUSUMMARY
The City's Public Works Department is requesting site plan approval for an 82,500 square -foot
public works building with a conditional use permit for outdoor storage areas. The variance
requests are to permit the parking lot to be closer to the wetland and the creek than is permitted by
ordinance.
The proposed development will occur on
two lots of record: Lots 5 and 6, Block 1,
Chanhassen Lake Business Park 50'
Addition. All this area is zoned IOP. The
property to the north of the site contains
Paisley Park. The property immediately
to the east is a City owned outlot
containing woodlands and Riley Creek.
The property to the south is vacant and
contains portions of a large wetland
complex which crosses over onto this site.
The property to the west across Audubon
Road contains Pillsbury, a vacant
industrial property, and a day care facility.
Water and sewer service is available to the
site in Park Place. Access to the site will
be provided via Park Place.
The high point of the property is on the west side with an elevation of 974. The low point is in the
south central portion of the property in the wetland with an elevation of approximately 920. While
there is over a 50-foot elevation change on the property, there are no bluffs on the property since the
slope does not exceed 25 percent (a bluff must have both an elevation change of 25 feet or more and
a slope of 30 percent or greater). The western half of the property is heavily wooded. A wetland
exists in the south central portion of the property and extends onto the property to the south. A
wooded corridor along Riley Creek is located to the east of the properties.
Staff is recommending approval of the Site Plan Review to permit an 82,500 square -foot public
works building with variances from the wetland setback and creek setback, and a conditional use
permit for the outdoor storage. As part of the process, the City will create a zoning lot of the two
lots creating, in effect, one building site. Additionally, the City must vacate some drainage and
utility easements and a portion of the right-of-way.

GENERAL SITE PLAN/ARCHITECTURE
The applicant is requesting site plan approval for an 82,500
square -foot, one-story officelwarehouse building with a
mezzanine storage area with outdoor storage areas to the rear
of the building and setback variances for the parking lot area
from Riley Creek to the east and the wetland to the south.
ARCHITECTURAL COMPLIANCE
Size Portion Placement
The main entrance to the building is located in the southeast comer of the building. The building
entrance consists of full -story store front, glass windows and doors. A metal canopy is proposed
over the entrance.
Material, Color and Detail
Materials consist of ribbed, insulated, precast tip -up concrete panels with exposed aggregate
incorporating random smooth banding and brick. The office area and all portions of the building
that project from the plane of the building are completely in brick. The concrete would be light
gray with a buff -colored stone exposed aggregate. The brick we are proposing is a modular -
sized brick in a dark brown earth tone with a color -matched mortar. The majority of the pre -
finished metal (overhead doors, coping, fascia, etc.) will be a charcoal gray color with dark
bronze accents at elements such as signage and window trims.
Clerestory windows are provided around the building with the use of large window areas over
the office area and the vehicle maintenance bays. These upper level windows will permit natural
lighting. Full-length store -front type windows are included in the office area of the building in
addition to the more traditional aluminum -framed windows in the offices and multi -purpose
room. The proposed glass is a low-e 1-inch insulated glass with a medium bronze tint. The
Chanhassen Public Works Facility
Planning Case 08-25
January 6, 2008
Page 5of15
window frames will be anodized aluminum. Soldier courses of brick are proposed above the
windows and at the top of the brick walls.
Height and Roof Design
The building height varies depending on the area of the building. Building roofs are proposed to
be flat. Parapet heights go to 26 feet in the vehicle maintenance and welding bays, 24 feet in the
vehicle storage and shop areas, 20 feet in the wash bays, and 14 and 19' 8" in the office areas.
The varying roof heights provide architectural interest to the building.
Mechanical equipment, if visible to the public, will be screened with prefinished metal screening.
Facade Transparency
Over 50 percent of the first floor elevation in the office area that is viewed by the public includes
transparent windows and/or doors. All other areas shall include landscaping material and
architectural detailing and articulation.
For buildings with a use or function that does not readily allow windows, e.g., cooler or freezer
areas, mechanical rooms, security areas, storage areas or warehouse or manufacturing space in
commercial or industrial buildings, the fenestration standards may be reduced. However, the
architecture detailing must be provided by the use of upper level windows, the use of spandrel
glass or architectural detailing which provides arches, patterning, recesses and shadowing that
provide aesthetic interest.
Site Furnishing
Community features may include landscaping, lighting, benches, tables, etc. The development
has a proposed patio area on the east side of the building. Additionally, a significant landscape
area is being preserved at the southeast comer of the building.
Chanhassen Public Works Facility
Planning Case 08-25
January 6, 2008
Page 6 of 15
Loading Areas, Refuse Area, etc.
Screening of service yards, refuse
and waste removal, other unsightly
areas and truck parking/loading
areas is provided by locating such
areas on the north side of the
building. Since this site is at the end
of a cul-de-sac, the public will not,
generally, be able to view these areas
without entering the site.
Lot Frontage and Parking Location
Parking areas are located to the east and south side of the building. Due to the site's location at
the end of a cul-de-sac, only a few parking stalls are provided between the right-of-way and the
building.
LIGHTING/SIGNAGE
Area lighting is provided in the parking lot islands east of the building as well as at the refueling
station. Lighting height is 30 feet with shoebox type fixtures and high-pressure sodium light
bulbs. Additionally, wall -mounted light fixtures are proposed on the building with architectural
sconce lighting and arm -mounted box lighting.
The plans show a wall sign on the east side of the building just north of the entrance with a
maple leaf and 12-inch high aluminum letters. Signage shall require a separate sign permit
review to determine compliance with City ordinance.

LANDSCAPING
Minimum requirements for landscaping include 17,696 square feet of landscaped area around the
parking lot, two landscape islands or peninsulas, 70 trees for the parking lot, and bufferyard
plantings along the property lines. The applicant's proposed as compared to the requirements for

STREETS, SITE ACCESS AND SITE CIRCULATION
There are no public streets proposed or required for development of this site. Park Place
provides access to the site. No right-of-way acquisition is required for the public street.
The existing terminus of Park Place is a 100-foot diameter cul-de-sac within a 120-foot diameter
right-of-way. The entire paved cul-de-sac will be removed and some paving will be necessary in
the right-of-way.
The southern access is 36 feet wide and will provide access to the cold storage area of the
building. The northern access is shown as approximately 47 feet wide. The northern access
must be revised so that the maximum width does not exceed 36 feet.
A portion of the parking area lies within the existing 120-foot diameter cul-de-sac right-of-way.
The proposed public use of the property does not necessarily warrant vacating the cul-de-sac
right-of-way; however, should the property be sold in the future, the parking lot improvements
may need to be removed and a standard public cul-de-sac installed. An encroachment agreement
is required for the portion of the parking area that lies within the public right-of-way.
GRADING(DRAINAGE
The site was mass graded under an Interim Use Permit approved by City Council on September
2, 2008. Final grading will occur with the construction of the building and parking lot. Runoff
from the majority of the site will be conveyed to the off -site stormwater treatment pond southeast
of the site via storm sewer.
Roof drains along the west side of the building will outlet to a drainage swale on the west side of
the building which discharges to the wetland south of the building.
Runoff from the access to the cold storage area is proposed to outlet to the wetland. If feasible,
this runoff should be conveyed to the existing storm sewer so that it can be treated by the
existing stormwater basin.
Revised drainage calculations and storm sewer sizing must be submitted to ensure that the
existing downstream infrastructure can accommodate the proposed runoff.
Three retaining walls are proposed on the site. A 280-foot long wall is proposed along the north
side of the paved area with a maximum height of 14 feet. This wall will be constructed within
the existing drainage and utility easement and will therefore require an encroachment agreement.
Chanhassen Public Works Facility
Planning Case 08-25
January 6, 2008
Page 9 of 15
The second wall is a 100-foot long wall around a 45-inch oak tree on the south side of the
building with a maximum height of four feet. A I I5-foot long wall is proposed on the south side
of the access to the cold storage area; the maximum height of this wall is four feet.
The proposed top and bottom of wall elevations must be shown. Walls taller than four feet must
be designed by an engineer registered in the State of Minnesota and require a building permit.
According to the recorded plat, there were no drainage and utility easements platted along the
common lot line. The site plan must show the dimensions of the lots.
UTILITIES
Metropolitan Council Environmental Services has a 30-inch diameter sanitary sewer interceptor
that runs along the east side of the site. The City of Chanhassen has a 21-inch diameter trunk
sanitary sewer along the east side of the site as well. A 10-inch sanitary sewer extends west from
the City's trunk line, then to the southwest within a 20-foot wide drainage and utility easement.
A portion of this pipe has been abandoned, therefore, a portion of the drainage and utility
easement must be vacated.
A 10-inch watermain was installed on the east and north side of the site with the Chanhassen
Lakes Business Park 5'h Addition improvements. A portion of this watermain has been
abandoned.
The existing drainage and utility easements and abandoned utilities must be labeled on the plan
sheet.
Storm sewer will be installed to serve the proposed development. This storm sewer will connect
to the existing public utility. The utility plan must include a note regarding the connection to the
existing storm sewer.
EROSION AND SEDIMENT CONTROL
A NPDES Phase II Construction Site Storm Water Permit has been obtained from the Minnesota
Pollution Control Agency (MPCA) for this site. The Storm Water Pollution Prevention Plan
(SWPPP) has been prepared and supplied to the Carver Soil and Water Conservation District for
their review and comment.
The SWPPP needs to include the total area disturbed, the total change in impervious surface as
well as all pertinent contact information. The SWPPP should be amended to include sequencing
of events during the construction of the site. All wetlands need to be clearly labeled in the
erosion control plan.
As indicated on the plan, erosion control blanket shall be installed on all slopes greater than or
equal to 3:1. At a minimum, this includes those slopes immediately east of the existing wetland
basins. This appears to have been addressed in the erosion control plan. All exposed soil areas
shall have temporary erosion protection or permanent cover year round. The NPDES permit has
Chanhassen Public Works Facility
Planning Case 08-25
January 6, 2008
Page 10 of 15
been revised such that all slopes must be protected within 14 days regardless of the grade unless
special provisions are applied.
These areas include, but are not limited to, constructed storm water management features side
slopes, and any exposed soil areas with a positive slope to a storm water conveyance system,
such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or
other natural or manmade systems that discharge to a surface water.
Inlet protection may be needed prior to installation of the castings for the curbside catch basins.
In that case, all storm sewer inlets should be protected by at least fabric draped over the manhole
with a steel plate holding the fabric in place.
WETLANDS
One jurisdictional wetland exists on site. The wetland was delineated by Terry Jeffery in August
of 2008. At this time, an historic review of aerial photography, USGS topographic maps and
civil engineering plans was performed. It was determined, based upon this review, that the
wetland increased in size as a result of grading changes to the topography of the area and new
directed inputs from land development.
The wetland is classified as Manage 2 in the Chanhassen Surface Water Management Plan. This
management classification requires a 20-foot wetland buffer and a 30-foot setback from this
buffer.
It appears that, in part due to the desire to preserve a significant oak tree on the site, the buffer
will be as narrow as 16.5 feet for a length of 95 feet. Additional buffer should be set aside so
that the buffer is the same by unit area. A 20-foot buffer on the property would amount to 9,777
square feet. The proposed buffer encroachment amounts to 321 square feet. The buffer should
be expanded to mitigate for at least this 321 square feet of area.
Further, the drive aisle is located entirely within the 30-foot setback from the buffer's edge. A
30-foot variance will be needed for the construction of this drive aisle. In the event that a
variance is granted, any design should seek to mitigate for the lost functions and values from the
encroachment into the setback zone.
A portion of the stormwater is to be directed to the pond located east of Park Place. This is
identified as a Manage 2 wetland in the Surface Water Management Plan. However, the historic
review clearly shows that this area was excavated for the express purpose of addressing
stormwater management for the development of the business park and is not a jurisdictional
wetland under the Wetland Conservation Act of Minnesota. This pond is tributary to Riley
Creek and Lake Susan. Therefore, all reasonable efforts should be taken to assure that the input
of new stormwater does not result in downstream degradation of water quality.

PUBLIC WATERS AND BLUFFS
There are no bluff zones located on or immediately adjacent to the property. There is one DNR
stream that flows along the eastern property boundary. This stream is Riley Creek. This reach
of Riley Creek is not listed as impaired. Riley Creek from Lake Susan to the Minnesota River is
impaired as is the Minnesota River. No additional stormwater or surface drainage should be
directed to the creek and the watershed should be modified as little as practicable to achieve the
development goals.
The channel and the immediate top of bank have been degraded due to past land use in the area.
Much of the degradation can be seen in the form of debris within and adjacent to this channel.
This debris needs to be cleaned up as part of the site development. Further, several reaches of
Riley Creek have been denuded of vegetation or is dominated by invasive species such as
buckthorn and garlic mustard. Vegetation management should occur adjacent to the channel to
assure that an adequate and beneficial buffer is maintained along the channel. Work with the
Environmental Resources Specialist and the Water Resources Coordinator to design and manage
this work.
SURFACE WATER MANAGEMENT PLAN (SWMP) CONNECTION CHARGES
No SWMP fees are required for this project.
OTHER AGENCIES
The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g.,
Minnesota Pollution Control Agency, Minnesota Department of Natural Resources (for
dewatering)) and comply with their conditions of approval.
MISCELLANEOUS
The buildings are required to have automatic fire extinguishing systems. Building plans must be
prepared and signed by design professionals licensed in the State of Minnesota. Retaining walls
over four feet high must be designed by a professional engineer and a permit must be obtained
prior to construction. Detailed occupancy related requirements will be addressed when complete
building plans are submitted. The owner and/or their representative shall meet with the
Inspections Division as soon as possible to discuss plan review and permit procedures.
VARIANCE
Chanhassen code requires that structures be set back from the top of bank of streams a minimum
of fifty (50) feet. Based upon the plans provided, the back of curb for the parking area is less
than 50 feet from the channel in at least two places. The more northerly encroachment would
require a 25-foot variance and the more southerly encroachment would require a 15-foot
variance. The applicant is requesting a 3.5-foot encroachment into the minimum wetland buffer
requirement. The applicant is requesting a 30-foot variance for the wetland setback.
Chanhassen Public Works Facility
Planning Case 08-25
January 6, 2008
Page 12 of 15
The meandering nature of the creek to the east of the property does not permit a uniform parking
lot drive aisle design. The wetland on the south restricts the location of buildings and access
drives on the site. The tree -covered slope on the west also constrains the development of the
property. In order to avoid setback variances, the building would have to be shifted to the west,
requiring extensive grading in the tree -covered slope.
The channel and the immediate top of bank have been degraded due to past land use in the area.
Much of the degradation can be seen in the form of debris within and adjacent to this channel.
This debris needs to be cleaned up as part of the site development. Several reaches of Riley
Creek have been denuded of vegetation or is dominated by invasive species such as buckthorn
and garlic mustard. Vegetation management should occur adjacent to the channel to assure that
an adequate and beneficial buffer is maintained along the channel. Work with the Environmental
Resources Specialist and the Water Resources Coordinator to design and manage this work.
Staff has reviewed the files to determine if there have been any other variances in the area. Out of
the 500-foot search area, there was one setback variance #88-14:

CONDITIONAL USE PERNIIT
Screened outdoor storage requires a conditional use permit. Outdoor storage areas are an
integral component of the public works operation. The City must be able to store materials and
supplies to fulfill its obligations to the public.
Sec. 20-308. Screened outdoor storage.
The following applies to screened outdoor storage:
(1) All outdoor storage must be completely screened with one -hundred percent opaque fence or
landscaped screen.
The areas to the north, west and east of the storage area are heavily wooded. The building,
located to the south, will screen the storage area from the public right-of-way. The proposed
development must comply with the approved site plan.

CITY OF CHANHASSEN
CARVER AND HENNEPIN COUNTIES, NIINNESOTA
FINDINGS OF FACT
AND RECOMMENDATION
Application of the City of Chanhassen for Site Plan Review for a Public Works Facility,
Planning Case #08-25, for an 82,500 square -foot, one-story office/warehouse building with a
mezzanine storage area, a conditional use permit for outdoor storage and setback variances from
the creek and wetland for the parking lot area.
On January 6, 2009, the Chanhassen Planning Commission met at its regularly scheduled
meeting to consider the application of the City of Chanhassen for a site plan review for a public
works facility for the property located at Lots 5 & 6, Block 1, Chanhassen Lakes Business Park
5' Addition (7901 Park Place). The Planning Commission conducted a public hearing on the
proposed site plan which was preceded by published and mailed notice. The Planning
Commission heard testimony from all interested persons wishing to speak and now makes the
following:
FINDINGS OF FACT
1. The property is currently zoned Industrial Office Park, IOP, District.
2. The property is guided by the Land Use Plan for Office -Industrial uses.
3. The legal description of the property is: Lots 5 & 6, Block 1, Chanhassen Lakes Business
Park 5 h Addition
4. Site Plan Review
a. The proposed project is consistent with the elements and objectives of the city's
development guides, including the comprehensive plan, official road mapping, and other
plans that may be adopted;
b. The proposed project is consistent with this division;
c. The proposed project preserves the site in its natural state to the extent practicable by
minimizing tree and soil removal and designing grade changes to be in keeping with the
general appearance of the neighboring developed or developing or developing areas;
d. The proposed project creates a harmonious relationship of building and open space with
natural site features and with existing and future buildings having a visual relationship to
the development;
e. The proposed project creates a functional and harmonious design for structures and site
features, with special attention to the following:
1) An internal sense of order for the buildings and use on the site and provision of a
desirable environment for occupants, visitors and general community;
2) The amount and location of open space and landscaping;
3) Materials, textures, colors and details of construction as an expression of the design
concept and the compatibility of the same with adjacent and neighboring structures
and uses; and
4) Vehicular and pedestrian circulation, including walkways, interior drives and parking
in terms of location and number of access points to the public streets, width of interior
drives and access points, general interior circulation, separation of pedestrian and
vehicular traffic and arrangement and amount of parking.
f. The proposed project protects adjacent and neighboring properties through reasonable
provision for surface water drainage, sound and sight buffers, preservation of views, light
and air and those aspects of design not adequately covered by other regulations which
may have substantial effects on neighboring land uses.
5. Variance: The Board of Adjustments and Appeals shall not recommend and the City Council
shall not grant a variance unless they find the following facts:
a. That the literal enforcement of this chapter would cause an undue hardship. Undue
hardship means that the property cannot be put to reasonable use because of its size,
physical surroundings, shape or topography. Reasonable use includes a use made by a
majority of comparable property within 500 feet of it. The intent of this provision is not
to allow a proliferation of variances, but to recognize that there are pre-existing standards
in this neighborhood. Variances that blend with these pre-existing standards without
departing downward from them meet this criterion. The meandering nature of the creek
to the east of the property does not permit a uniform parking lot drive aisle. The wetland
on the south restricts the location of buildings on the site. The tree -covered slope on the
west also constrains the development of the property. Based on the revisions to the plans,
the variance request has been reduced to a minimum.
b. The conditions upon which a petition for a variance is based are not applicable, generally,
to other property within the same zoning classification. This condition is unique to this
property which abuts Riley Creek. In order to avoid setback variances, the building
`A
would have to be shifted to the west, requiring extensive grading in the tree -covered
slope.
c. The purpose of the variation is not based upon a desire to increase the value or income
potential of the parcel of land, but rather minimize the impacts to the water resources and
to avoid additional impacts on the wooded slope. Because of the nature of the facility,
vehicle size, outdoor storage, etc, need large space, turning radius of tandem axle
vehicles, storage of salt, pea rock, mulch, and trailers
d. The alleged difficulty or hardship is not a self-created hardship, but is due to the unique
site features which include a creek to the east, just east of the public street, a wetland on
the south, a tree -covered slope to the west and converging side property lines.
Additionally, the City has attempted to save a 45 inch oak tree southeast of the building.
e. The granting of the variance for the construction of a public works building will not be
detrimental to the public welfare or injurious to other land or improvements in the
neighborhood in which the parcel is located, but will facilitate the provision of a required
public service. In addition, the City will be implementing several mitigation measures
which should improve the natural environment including:
• Currently from the top of bank for Riley creek west is either denuded of vegetation or
dominated by invasive plant species
• Currently the channel and the area immediately adjacent to the channel has a
substantial amount of construction debris
o The plan will involve cleaning all debris away from within the channel and
between the proposed back of curb and top of bank.
o This area will be planted with native trees, shrubs, forbs and grasses — a detailed
vegetation management plan will be created
o Areas of scour which have developed in the channel will be stabilized.
• The buffer will be expanded both northeast and northwest of the wetland so that total
buffer will be far greater than what is required under City code.
• Much of the buffer is dominated by reed canary grass - an invasive species. This will
be replaced by a special BWSR seed mix.
• An engineered wetland will be created northeast of the wetland to treat runoff from
the driveway prior to entering the wetland.
• A bio-filtration swale will be created west of the building to treat roof runoff prior to
entering the wetland.
f. The proposed variation will not impair an adequate supply of light and air to adjacent
property or substantially increase the congestion of the public streets or increase the
danger of fire or endanger the public safety or substantially diminish or impair property
values within the neighborhood.
KI
6. Conditional Use Permit:
a. The proposed outdoor storage will not be detrimental to the public health, safety, comfort,
convenience or general welfare of the neighborhood or the city.
b. The proposed outdoor storage will be consistent with the objectives of the city's
comprehensive plan and this chapter.
c. The proposed outdoor storage will be designed, constructed, operated and maintained so
to be compatible in appearance with the existing or intended character of the general
vicinity and will not change the essential character of that area.
d. The proposed outdoor storage will not be hazardous or disturbing to existing or planned
neighboring uses.
e. The proposed outdoor storage will be served adequately by essential public facilities and
services, including streets, police and fire protection, drainage structures, refuse disposal,
water and sewer systems and schools; or will be served adequately by such facilities and
services provided by the persons or agencies responsible for the establishment of the
proposed use.
f. The proposed outdoor storage will not create excessive requirements for public facilities
and services and will not be detrimental to the economic welfare of the community.
g. The proposed outdoor storage will not involve uses, activities, processes, materials,
equipment and conditions of operation that will be detrimental to any persons, property or
the general welfare because of excessive production of traffic, noise, smoke, fumes, glare,
odors, rodents, or trash.
h. The proposed outdoor storage will have vehicular approaches to the property which do
not create traffic congestion or interfere with traffic or surrounding public thoroughfares.
The proposed outdoor storage will not result in the destruction, loss or damage of solar
access, natural, scenic or historic features of major significance.
j. The proposed outdoor storage will be aesthetically compatible with the area.
k. The proposed outdoor storage will not depreciate surrounding property values.
1. The proposed outdoor storage will meet standards prescribed for certain uses as provided
in the City Code.
7. The planning report #08-25 dated January 6, 2009, prepared by Robert Generous, et al, is
incorporated herein.
RECOMMENDATION
The Planning Commission recommends that the City Council approve the site plan review
for an 82,500 square -foot, one-story office/warehouse building with a mezzanine storage area, a
conditional use permit for outdoor storage and setback variances from the creek and wetland for
the parking lot area.

Re: Chanhassen Public Works Facility
The SWCD has reviewed the above mentioned development plan for erosion and sediment controls.
Following you will find my comments.
-A National Pollution Discharge Elimination System permit will be required for this development.
-The General Contractor who has overall charge of day to day operations needs to be on the NPDES
Permit as the contractor. The Owner and or General Contractor have the responsibility for the NPDES
permit. An individual qualified to complete stormwater inspection must complete reports weekly, and
after each %z inch rainfall event. A box will need to be placed on site for these specific documents, and or
kept in the project office.
The Carver SWCD will be completing inspections of the Hiles of the NPDES permit and city ordnances
to see if the owner and or contractor are in compliance with the permit. This permit is a self
maintained permit. Guidelines of the permit can be found at the following web site:
http://www.i)ca.state.mn.us/water/stormwater/stormwater-c.htnd
Erosion Control
I. Unless I missed it, the SWPPP only discusses stabilization of slopes —does not indicate what types of
stabilization is needed and timing of placement.
Sediment Control
1. Inlet protection is needed on all stormwater conveyance systems prior to casting. The SWPPP
discusses inlet protection, but no mention of what detail is needed. Inlet protections need to be
installed within 24 hours of placement
2. After installation of curb and gutter, all positive slopes to the street with exposed soils will need to be
stabilized. Curb and gutter / inlets are "surface waters" which need protection from exposed soils
with a positive slope within 200 linear feet.
3. Concrete washout plans are included, but needs to have the block layers with there Spec Mixes areas
contained also.
4. The General Contractor must discuss De -watering plans with all Sub -Contractors to make sure they
are aware of the NPDES requirements.
5. During construction, the roof water draining area will need to have temporary sediment measures
installed, bio-rolls are noted on page 4 of 9, but does not indicate when it should be applied.
6. Flared end section outletting into swale that flows to the wetland needs to be stabilized immediately
once pipe is connected.
AN EQUAL OPPORr1NFY EMPLOYER
Please include me with any correspondences of changes to this original concept plan, and also of any pre -
construction meetings prior to start of construction.

CITY OF CHANHASSEN
CARVER AND HENNEPIN COUNTIES, MINNESOTA
FINDINGS OF FACT
AND RECOMMENDATION
Application of the City of Chanhassen for Site Plan Review for a Public Works Facility,
Planning Case #08-25, for an 82,500 square -foot, one-story office/warehouse building with a
mezzanine storage area, a conditional use permit for outdoor storage and setback variances from
the creek and wetland for the parking lot area.
On January 6, 2009, the Chanhassen Planning Commission met at its regularly scheduled
meeting to consider the application of the City of Chanhassen for a site plan review for a public
works facility for the property located at Lots 5 & 6, Block 1, Chanhassen Lakes Business Park
5°i Addition (7901 Park Place). The Planning Commission conducted a public hearing on the
proposed site plan which was preceded by published and mailed notice. The Planning
Commission heard testimony from all interested persons wishing to speak and now makes the
following:
FINDINGS OF FACT
1. The property is currently zoned Industrial Office Park, IOP, District.
2. The property is guided by the Land Use Plan for Office -Industrial uses.
3. The legal description of the property is: Lots 5 & 6, Block 1, Chanhassen Lakes Business
Park 5"' Addition
4. Site Plan Review
a. The proposed project is consistent with the elements and objectives of the city's
development guides, including the comprehensive plan, official road mapping, and other
plans that may be adopted;
b. The proposed project is consistent with this division;
c. The proposed project preserves the site in its natural state to the extent practicable by
minimizing tree and soil removal and designing grade changes to be in keeping with the
general appearance of the neighboring developed or developing or developing areas;
ac"Ma
d. The proposed project creates a harmonious relationship of building and open space with
natural site features and with existing and future buildings having a visual relationship to
the development;
e. The proposed project creates a functional and harmonious design for structures and site
features, with special attention to the following:
1) An internal sense of order for the buildings and use on the site and provision of a
desirable environment for occupants, visitors and general community;
2) The amount and location of open space and landscaping;
3) Materials, textures, colors and details of construction as an expression of the design
concept and the compatibility of the same with adjacent and neighboring structures
and uses; and
4) Vehicular and pedestrian circulation, including walkways, interior drives and parking
in terms of location and number of access points to the public streets, width of interior
drives and access points, general interior circulation, separation of pedestrian and
vehicular traffic and arrangement and amount of parking.
f. The proposed project protects adjacent and neighboring properties through reasonable
provision for surface water drainage, sound and sight buffers, preservation of views, light
and air and those aspects of design not adequately covered by other regulations which
may have substantial effects on neighboring land uses.
5. Variance: The Board of Adjustments and Appeals shall not recommend and the City Council
shall not grant a variance unless they find the following facts:
a. That the literal enforcement of this chapter would cause an undue hardship. Undue
hardship means that the property cannot be put to reasonable use because of its size,
physical surroundings, shape or topography. Reasonable use includes a use made by a
majority of comparable property within 500 feet of it. The intent of this provision is not
to allow a proliferation of variances, but to recognize that there are pre-existing standards
in this neighborhood. Variances that blend with these pre-existing standards without
departing downward from them meet this criterion. The meandering nature of the creek
to the east of the property does not permit a uniform parking lot drive aisle. The wetland
on the south restricts the location of buildings on the site. The tree -covered slope on the
west also constrains the development of the property. Based on the revisions to the plans,
the variance request has been reduced to a minimum.
b. The conditions upon which a petition for a variance is based are not applicable, generally,
to other property within the same zoning classification. This condition is unique to this
property which abuts Riley Creek. In order to avoid setback variances, the building
2
would have to be shifted to the west, requiring extensive grading in the tree -covered
slope.
The purpose of the variation is not based upon a desire to increase the value or income
potential of the parcel of land, but rather minimize the impacts to the water resources and
to avoid additional impacts on the wooded slope. Because of the nature of the facility,
vehicle size, outdoor storage, etc, need large space, turning radius of tandem axle
vehicles, storage of salt, pea rock, mulch, and trailers
d. The alleged difficulty or hardship is not a self-created hardship, but is due to the unique
site features which include a creek to the east, just east of the public street, a wetland on
the south, a tree -covered slope to the west and converging side property lines.
Additionally, the City has attempted to save a 45 inch oak tree southeast of the building.
e. The granting of the variance for the construction of a public works building will not be
detrimental to the public welfare or injurious to other land or improvements in the
neighborhood in which the parcel is located, but will facilitate the provision of a required
public service. In addition, the City will be implementing several mitigation measures
which should improve the natural environment including
• Currently from the top of bank for Riley creek west is either denuded of
vegetation or dominated by invasive plant species
• Currently the channel and the area immediately adjacent to the channel has a
substantial amount of construction debris
o The plan will involve cleaning all debris away from within the channel and
between the proposed back of curb and top of bank.
o This area will be planted with native trees, shrubs, forbs and grasses — a detailed
vegetation management plan will be created
o Areas of scour which have developed in the channel will be stabilized.
• The buffer will be expanded both northeast and northwest of the wetland so that
total buffer will be far greater than what is required under City code.
• Much of the buffer is dominated by reed canary grass - an invasive species. This
will be replaced by a special BWSR seed mix.
• An engineered wetland will be created northeast of the wetland to treat runoff
from the driveway prior to entering the wetland.
• A bio-filtration swale will be created west of the building to treat roof runoff prior
to entering the wetland.
f. The proposed variation will not impair an adequate supply of light and air to adjacent
property or substantially increase the congestion of the public streets or increase the
danger of fire or endanger the public safety or substantially diminish or impair property
values within the neighborhood.
6. Conditional Use Permit:
a. The proposed outdoor storage will not be detrimental to the public health, safety, comfort,
convenience or general welfare of the neighborhood or the city.
b. The proposed outdoor storage will he consistent with the objectives of the city's
comprehensive plan and this chapter.
c. The proposed outdoor storage will be designed, constructed, operated and maintained so
to be compatible in appearance with the existing or intended character of the general
vicinity and will not change the essential character of that area.
d. The proposed outdoor storage will not be hazardous or disturbing to existing or planned
neighboring uses.
e. The proposed outdoor storage will be served adequately by essential public facilities and
services, including streets, police and fire protection, drainage structures, refuse disposal,
water and sewer systems and schools; or will be served adequately by such facilities and
services provided by the persons or agencies responsible for the establishment of the
proposed use.
f. The proposed outdoor storage will not create excessive requirements for public facilities
and services and will not be detrimental to the economic welfare of the community.
g. The proposed outdoor storage will not involve uses, activities, processes, materials,
equipment and conditions of operation that will be detrimental to any persons, property or
the general welfare because of excessive production of traffic, noise, smoke, fumes, glare,
odors, rodents, or trash.
h. The proposed outdoor storage will have vehicular approaches to the property which do
not create traffic congestion or interfere with traffic or surrounding public thoroughfares.
i. The proposed outdoor storage will not result in the destruction, loss or damage of solar
access, natural, scenic or historic features of major significance.
j. The proposed outdoor storage will be aesthetically compatible with the area.
k. The proposed outdoor storage will not depreciate surrounding property values.
1. The proposed outdoor storage will meet standards prescribed for certain uses as provided
in the City Code.
7. The planning report #08-25 dated January 6, 2009, prepared by Robert Generous, et al, is
incorporated herein.
RECOMMENDATION
The Planning Commission recommends that the City Council approve the site plan review
for an 82,500 square -foot, one-story office/warehouse building with a mezzanine storage area, a
conditional use permit for outdoor storage and setback variances from the creek and wetland for
the parking lot area.

RECEIVED
MAY 1 3 2009
CITY OF CHANHASSEN
The Board of Managers of the Riley -Purgatory -Bluff Creek Watershed District has reviewed
the additional plans and your response to our letter dated February 9th regarding the
Chanhassen Public Works Facility. We appreciate your detailed response.
The information you provided indicates that all of the runoff from the site will eventually
flow to the existing stormwater pond southeast of the site. This stormwater pond then
discharges to Riley Creek. While it appears that the additional chloride loading to
Riley Creek would be minimal we encourage the city to implement good housekeeping
practices to mitigate any unnecessary chloride loading to Riley Creek.
We also request that the City assure that any fuel spills will be properly mitigated. Given
that Riley Creek is impaired for turbidity, please provide your calculations that show that
the water quality volume treated by the existing pond is one inch of runoff from the new
impervious surfaces created by the project.
We are aware that the City requested and granted variances for this project. Our
understanding of the variances indicate that they are not justifiable. Setbacks are provided
to buffer sensitive resources from the impacts of increased impervious areas. The setbacks
currently in the City ordinance are the minimum that are considered protective of these

Subject: Chanhassen Public Works Facility CITY OF CHANHASSEN
Planning Case 08-25
Dear Mr. Generous:
The Board of Managers of the Riley -Purgatory -Bluff Creek Watershed District has reviewed
the plans you provided for the Chanhassen Public Works Facility. The City provided the
project information to the District to solicit comments and recommendations concerning the
impact of the project on storm water drainage, among other items.
The project will result in the creation of 41% impervious surface. The storm water drainage
from the paved area enters a catch basin and flows by storm sewer to Lake Susan. The roof
drainage is routed to a biofiltration Swale.
We reviewed the information provided and offer the following comments and questions:
1. Was consideration given to routing runoff from the paved area to a rain garden or
other similar system? Was porous pavement considered? Would the soil type
support such systems? The intent would be to limit the flow volume and amount of
pollutants entering the storm sewer and eventually Lake Susan.
2. How will fuel related spills be mitigated?
3. The sand/salt storage area is located immediately adjacent to the paved area catch
basin. Is the sand/salt storage area covered or enclosed? How will runoff from the
sand/salt area be prevented from entering the catch basin?
4. Will the catch basin that's adjacent to the sand/salt area and fuel island have an
isolation valve in case of spills?
5. State SWPPP requirements specify a temporary storm basin be provided for projects
greater than 5 acres. As this project exceeds 5 acres in size, please identify where the
temporary sedimentation basin will be located.
6. We are pleased to see that the city is planning on routing the roof drainage to a
biofiltration Swale. Please provide Swale drawings and calculations of the flow that
will be directed to the Swale. Was a green roof considered?

The Pemnittell shall implement the following pollution prevention management measures on the site:
of the NPDES construction permit
Temporary/Permanent Drainage Ditches & Swoles' The normal wetted perimeter of any temporary
or permanent drainage ditch or Swale that drains water from any portion of the construction
site, or diverts water around the site, must be stabilized within 200 lineal feet from the
property edge, or from the point of discharge into any surface water. Stabilization of the
last 200 lineal feet must be completed within 24 hours after connecting to a surface water.
Temporary or permanent ditches or swales that are being used as a sediment containment system
(with properly designed rock ditch checks, boo rolls, sit dikes etc.) do not need to be
stablized. These areas must be stabilized within 24 hours after no longer being used as a
sediment containment system.
Storm Sewer Outlets: Pipe outlets must be provided with temporary or permanent energy
nsepo van wi m hours after connection to a surface water.
Solid Waste: Collected sediment, asphalt and concrete millings, floating debris. paper,
plastic, fabric, construction and demolition debris and other wastes must be disposed of
properly and must comply with MPCA disposed requirements (Part IVF.1)
Hazardous Materials: 01, gasoline, paint and any hazardous substances must be property
stoned. including secondary, containment. to prevent spills, leaks or other discharge.
Restricted access to storage areas must be provided to prevent vandalism. Storage and
disposal of hazardous waste must be in compliance with MPCA regulations (Part IV F2).
Truck Washing: External washing of trucks and other construction vehicles must be united to
a defined area of the site. Runoff must be contained and waste property disposed of. No
engine degreasing is allowed an site(Part IV.F.3).
Concrete washout onsite: All liquid and solid wastes generated by concrete washout operations

Temporary or permanent dronaae ditches and sediment basins that are designed as part of a FINAL STABILIZATION (Part IVC)
sediment containment system (eq., ditches with rod check dams) require sediment control practices only as appropriate for site conditions (Part V.C.i.a).
Final Stabilization requires all of Parts IV.G.1-5 a Part IV.G.6 of the NPDES construction permit
I
Down gradient systems: If the down gradient treatment system is overloaded, additional up 7G% Vegetative Cover. Final Stabilization requires that all sail disturbing activities at the
gradient sediment control practices or redundant BMPS must be Installed to eliminate the site haw been completed and all soils must be stablized by a uniform, love permnid
overloading, and the SWPPP must be amended to identify Bore additional practices as required vegertall cover with a density of 70% over the entre perwms Surface area, or other
equivalent means necessary to prevent Seri failure under erosive conditions.

3:1 ell (or sleeper) must be less than 75 feet in length. In order to maintain sheet flow
and minimize rills and/or gullies, theme shall be no unbroken slope length of greater than 75
feet fa slopes with a grace of 3.1 m steeper (Pat IV.C.I.c).
Short—term activities: The liming of the installation of sediment control practices may be
adjusted to accommodate short—term actidties such as clewing or grubbing, a passage of
vehicles. Any short—term activity must be completed as quickly as possible and the sediment
control practices must be installed immediately after the activity is completed. However,
Sediment control practices must be installed before the next precipitation event even if the
activity is not complete (Part IVC.3).
Inlet Protection: All storm drain Mete must be protected by appropriate BMPS during
construction until all sources with potential for discharging to the Inlet haw been
stablized. Inlet protection may be removed for a particular inlet it a specific safety
concern (street flooding/freezing) has been identified and the Permittee(s) haw received
written correspondence from the jurisdictional authority (e.gcity/county/township/Mi-DOT
engineer) verifying the need fa removal. Written correspondence must be documented in the
SWPPP and available within 72 hours upon request. Permission to remove inlet protection
based on a specific Safety concern must still be obtained from the Imal jurisdictional
authority within 30 days of remold (Part IV.C.4).
Temporary soil stockpiles most how silt fence or other effective sediment controls, and
cannot be placed n surface waters, including stormrater conveyances such as curb and gutter
systems, or conduits and ditches unless there is a bypass in place for the stornwata (Part
VC 5)
Vehicle tracking of sediment from the construction site (or onto streets within the site)
must be minimized by BMPS Such as stone pads, concrete or steel wash rods, ar equivalent
systems. Street sweeping must be used if Such BMPs we not adequate to prevent Sediment from
beng tracked onto the street (Pat IVC6).
Final Clean rut of Permanent Slartnwater Treatment System: The Permittee(s) must ensure that
the permanent stormwater treatment system meets all design requirements in Part III.0 of the
NPDES construction permit This includes but is not limited to, a final clean out of
temporary or permanent se limenlotion basins that are to be used as permanent water quality
management basins and final construction or maintenance of infiltration basins. All sediment
must be removed from conveyance systems and ditches must be stablized with pemmvenl cover.
Removal of all Temporary BMPS: Prior to submission of the NOT, all temporary synthetic and
structural erosion prevention and sediment control BMPS (Such as silt fence) must be removed
on the portions of the site for which the Pernittee is responsible. BMPS designed to
decompose an site (Such as some compost logs) may be left in pine.
Projects an Agricultural Land: Fa construction projects on land used fa agricultural
purposes (e.g., ppelnes across crap ar range land) Final Stabilization may be accomplished
by resuming the disturbed land to its preconstruction agricultural use.
ADDITIONAL BMPS FOR SPECIAL OR IMPAIRED WATERS DURING
CONSTRUCTION ACTIVITY (APPENDIX A)
All requirements In Appendix A are in addition to BMPS already specified In the permit. Where
provisions of Appendix A conflict with requirements elsewhere in the permit, line provisions in
Appendix A lake precedence. All BMPS used to comply with this Appendix must be documented in the
SWPPP for the project (Appendix A.A).
Exposed Soils: All exposed soil areas must be stabilized within (7) days after the construction
activity in that portion of the site has temporarily or permanently cement (Appendix A.C.I.a)-
Temporay sediment basin requirements described in Part 111.8.1-5 of the NPDES construction permit
must be used far common drainage locations that saw an area with five (5) or mare acres disturbed
at one time (Appendix A. CA.b),
RECEIVING WATERS
There are no special or impaired waters within one (1) mile of the project location.
Roof drainage to be directed towards biolitration Swale located westerly an the property, This Swale will
discharge to the wetland located southerly an the property. The remainder of the site will be directed to
the slamwater, Pond located east of the construction site. Ultimate receiving water is Lake Susan.
A drainage map is included in the construction plan set.
The project engineer and the Construction Manager are responsible fa the implementation of the SWPPP
and the installation, inspection and maintenance of the erosion prevention and sediment control BMP's
before and during construction.
