City Council Meeting - March 8, 1993
Mayor Chmiel: It's been moved and seconded. Any other discussion?
Councilwoman Dockendorf: I just have one question. When did it get named
Arboretum Boulevard? That's a new one on me.
Paul Krauss: Well actually that was something that Morrish talked about. It's
been called, like I say it's been called a lot of things. I think if you look
at the Morrish study, he called the south boulevard Arboretum Boulevard and
the north boulevard Chanhassen Boulevard or something like that. 1
Councilwoman Dockendorf: Yeah, it makes more sense.
Councilman Wing: Yeah, how did that happen? ,
Paul Krauss: Well we realized that the south boulevard didn't have the
continuity that the north boulevard had so the north boulevard got the fancier
name.
Resolution *93 -19: Councilman Wing moved, Councilwoman Dockendorf seconded to
affirm the draft alternatives for analysis in the Environmental Assessment
document north of Highway 5 between Powers Boulevard and Highway 41. All voted
in favor and the motion carried unanimously.
PRELIMINARY PLAT TO SUBDIVISION 17.2 ACRES INTO 35 SINGLE FAMILY LOTS; REZONING
FROM A2, AGRICULTURAL ESTATES TO RSF, RESIDENTIAL SINGLE FAMILY, EAST OF COUNTY
ROAD 117, ONE -HALF MILE NORTH OF HIGHWAY 5, ROTLUND COMPANY.
Public Present:
Name Address
Don Jensen Rottlund Copmanies
Bret Davidson 7291 Galpin Blvd.
Jo Ann Olsen: This is a pretty simple subdivision. As you said, the applicant
is proposing to subdivide into 35 single family lots. There is really no
significant features of this site. It's been farmed. It's just a rolling
topography. There's no wetland, vegetation or anything. Planning Commission
did recommend approval with a couple of changes to the planning staff's
recommendations. We are recommending that the City Council adopt approval with
those changes to the conditions and the other staff conditions as were presented
to the Planning Commission.
Mayor Chmiel: Okay. Thank you Jo Ann. Is Rottlund here this evening? Would
you like to just give us a few words of wisdom.
Don Jensen: A few words of wisdom I'm not sure I can impart but Don Jensen,
Land Development Manager with Rottlund Company, 5201 East River Road, Fridley.
We've reviewed the staff report and all the various recommendations. We accept
those recommendations as good conditions. We have a couple of issues with items
number 3 and 4 of the report on page 8 that we received. We have been
discussing possibilities of temporary access and the future ponding that are
going to be required to the property to the north. Bret Davidson is here
58 ,
1
11 City Council Meeting - March 8, 1993
tonight to listen and for his own particular issues and clarifications. Part of
the drainage for this particular project goes off site in two different
directions and the city is asking by condition that the Rottlund Company put
temporary holding ponds on up to 3 of the lots, as well as pay cash in lieu of
IF future downstream ponding. We would just like the ability to work with staff
and the Council as you decide what the downstream ponding charges are. It's a
little bit ambiguous by the condition as to what the cap on those amounts might
be and we would just like that to be specific to the lots on our plan perhaps
that do not have the ponding provided for. The western portion of our
development does have a NURP pond and does control rate of release downstream.
So that's our main concern is conditions 3 and 4. Otherwise we are fine with
' all of the conditions, including the ones that were extended by the Planning
Commission, number 22. We would like to see perhaps a sunset to the temporary
ponding on the various lots. At such time as the city makes some downstream
' ponding available or that there's some type of timeframe that is attempted, so
that for the lots, if we do have lots where the building pad is taken out for
temporary ponding, that there is some due diligence or obligation on the part of
the city to continue to moving forward as quickly as progress allows for that to
' happen. And also, if in fact Mr. Davidson to the north is successful with his
application, that as soon as a final plat for that property occurs, that
conditions placed on this subdivision for temporary ponding would be removed. I
' think the staff report was written not contemplating what's going on immediately
around us and to the extent that we have a condition that is at least removed
when new development is ripe, we would prefer that. I have no further comments
' or questions, unless the Council or staff has those.
Mayor Chmiel: Jo Ann. With item number 22, there should be 22 conditions
contained and it shows 21 the Council should move on. And to put that drainage
easement must be granted for the pond located in the southwest corner and other
IL
temporary ponding areas is necessary.
' Jo Ann Olsen: Right. And on page 10, we're showing the changes and 22 should
be added as the changes to 1 and 20.
' Mayor Chmiel: Council action should take the 22 conditions rather than 21.
Jo Ann Olsen: Right. And the changes to 1 and 20. And as far as what Don has
brought up, we can work with that prior to final plat approval. That's really
' more for engineering to answer and I don't see any problem with it. I don't
know that we can put a cap on the fees. We can maybe, like you said, tie it in
with certain lots.
Don Jensen: Well we just wanted to get a chance to work with staff. It's
difficult to figure out what your end price is to assign values to homes and
lots if you ultimately don't know when the Council is going to act on the
' particular program that you're contemplating. The only other recommendation we
could have is, as solutions are brought, we would prefer that staff and the
Council look at conditions that might be tied to building permit rather than the
very front end. So if the lot is taken out for temporary ponding, that we're
not paying a fee for future downstream ponds, which this temporary ponds provide
our assistance for and pay for everything up front. Whereas if the city can
find a solution, only when those lots come through for building permit.

Mayor Chmiel: I think staff can probably discuss that with you and come up with
a conclusion.
Don Jensen: Thank you.

Mayor Chmiel: Move approval with all 22 conditions of Subdivision #93 -4 and 1

REVIEW PROPOSED HIGHWAY 41 REALIGNMENT IN CHASKA AND RELATED ISSUES.
Public Present:
Name Address ,
Ron Erickson MnDot
Harold Hesse
Paul Krauss: Mr. Mayor, I don't know who is in the audience that's present for
this one tonight. We do have a representative of MnDot here. Chaska was
supposed to send us a representative but I don't see one. You will recall that
this was an issue that was raised by, I think it was Bill Meyer at a Visitor
Presentation. He became aware of the fact that Chaska was proposing to
officially map and reserve some right -of -way for future realignment of Highway
41. We were not originally informed of that. We became aware of it at a late
hour and found out about it in advance of the City Council but you asked us to
return to you with information. Basically the proposal is in the Hesse Farms
area. Generally, here is the Highway 212 alignment that goes on into Chaska.
The proposal is to route 41 down here and across the river, which is shown in a
little bit more detail. If you look, key on these lots right over here. This
is that area in somewhat more detail with the Hesse Farm lots being right over
here. The Chanhassen /Chaska city line is right there. This is the Highway
alignment that's been aligned for two lanes. This however, an interchange where
this would be a highway to highway interchange. Northbound TH 41 to eastbound
212. The other one over there. We found out that there was in fact a lot of
information on this routing from time to time. I was just informed tonight too
that there was apparently some environmental workup that was done on this in the
very early 70's which is really, must have been one of the first EIS's because
the law was only approved I think when Nixon was President. But basically
you've got a highway that has been talked about conceptually for quite a period
of time but there's a difference between conceptually talking about a highway
and it's ultimate realization. We did find that Chaska really did make a, I
mean this has been on Chaska's docket for some time and we haven't necessarily
been a party to it but this is not something that Chaska just came up with.
There was even some documentation that the Metro Council looked at the 10 top
river crossings in the Twin Cities region, I think it was in 1989 and labeled
this as number 7. With a star. I found that very surprising. My understanding
is, because I don't have the whole report. I excerpted some of it in here.
That of the 7, or the 6 on top of it, either they're under construction right
now or in serious planning stages and I think they've built number 8. So that
would imply the Metro Council thought this had some importance. We looked into
it in great detail and we have some sensitivity to I guess not wanting to rock
