II SUBJ: Curry Farms Second Addition (Centex) ��Zj ����
Approval of Plans and Specifications
File No. 88-5
I Enclosed are the construction documents dated "Received June 22,
1988" for the second addition of the Curry Farms plat . The plans
include the construction of streets , sanitary sewer , watermain ,
I and storm sewer facilities. The City Council approved the final
plat for the second addition on May 9 , 1988 .
I During the review process for the first addition of Curry Farms ,
an evaluation of the overall watermain concept was performed to
investigate and ensure adequate capacity and flow conditions will
exist for the Curry Farms Subdivision. The proposed watermain lay-
Iout for the second addition is in accordance with the concept plan.
At present , the Reamer and Franco Loris residences do not possess
I municipal sanitary sewer and water service. The plans reflect
the installation of these additional services to accommodate both
residents. The actual connection between the house and property
Iline will be the responsibility of each resident.
The maximum proposed street grade meets the City' s 7 . 0% criteria.
On March 28 , 1988 , the City Council accepted the feasibility
I study for Teton Lane as prepared by William Engelhardt
Associates. Page 8 of the plan set includes the improvement as
directed by the Council. The proposed street profile minimizes
I the impact to the mature vegetation which exists along the
existing roadbed while keeping adequate sight distance near the
crest of the hill as you approach Lilac Lane. A turnaround is
proposed on the Donovan property in lieu of using the Natole dri-
ll veway since this would be more adequate for snow plowing. As you
may recall, Mr. Donovan stated during the March 28 , 1988 Council
meeting that he would be agreeable to an easement for the purpose
I of a turnaround on the edge of his property (refer to Attachment
2 ) . Further clarification with Mr. Donovan on June 24, 1988 is
that he is agreeable to provide the City with a 12 ' X 15 ' ease-
, ment for this purpose.

The proposed "Break-away" barricade is a standard design used by ,
MnDOT. We find that this is acceptable.
As part of the review process for the drainage of the second '
addition, staff felt that it was necessary to resolve the Kerber
drainage problem before continuing on with the second phase of
the project. As a result , the developer has agreed to replace
the existing 36-inch culvert along the Kerber property with a
42-inch arch storm sewer pipe , providing that the Kerbers provide
the necessary easement documents for the installation of the pipe
by the developer , and perpetual maintenance by the City. The
increased diameter and ability to maintain the drainageway aid in
avoiding the freeze-up situation as experienced last spring. The
developer will need to submit, for approval by the City Engineer,
a detail for the installation of this structure prior to the com-
mencement of any work on the Kerber property. The detail shall
provide for fill and grade over this arch pipe to provide safe
vehicle passage. Likewise, the City will not require the
installation of this portion of the project until the City is
provided with a suitable construction and maintenance easement
from the Kerbers.
Page 2 of the plan set proposes the installation of a corrugated
metal pipe through Lot 1 of Block 4 . City' s standards for urban
construction specify reinforced concrete pipe for this application.
It is therefore recommended that the plans and specifications
dated "Received June 22 , 1988" for the Curry Farms Second
Addition be approved upon the following conditions:
1 . The developer shall enter into a development contract with
the City and provide the necessary financial sureties to
guarantee the proper installation of these improvements .
2 . A detail sheet describing the installation and grading for i
the arch pipe on the Kerber property shall be provided for
approval by the City Engineer.
3. Work on the Kerber property shall not be started until the
City receives an acceptable construction and maintenance
easement. '
4. All sanitary sewer mains shall be televised after the mandrel
test has been successfully completed. A copy of the video
tape and a written report shall be sent to the City and will
remain the property of the City of Chanhassen.
5 . Wear course shall not be placed until the base course has been ,
through a freeze/thaw cycle, at which time approval from the
City Engineer must be received prior to placement.
Specifications shall call for two casting adjustments, i.e.
no bituminous ramping allowed.

City Council Meeting - March 28, 1988
somewhat skeptical that that plan is going to do it.
Gary Warren: It's going to come down to our city forces and the particular t'
individual who plows this area to have the marching orders that that's not
done. I guess we feel, it's not whether we have the right-of-way or not, they
plow the road and the snow builds up on the sides. We'll get it open and use
whatever area we need to do that and specific direction will be given to keep
the barricade area, don't use the snow as the barricade but keep that area
clean and I see that as a workable situation. -
Councilman Boyt: How can they take that truck and turn it around in there so
they can clean in front of that barricade? I don't understand how they can do
that.
Bill Engelhardt: I think the 33 feet, if we use a "T" in here, we should be
able to get enough so they can come in and probably push it ahead and "T" it on
both sides. Wing it on both sides and take it away from the front and put it
on this side and this side. It will happen. We'll have to work with it. It's
such a limited area up there.
Mayor Hamilton: Except that Mr. Donovan has been very cooperative and I would
suspect that if we asked him, he would allow us to put a "T" in at the end of
the street there. There's nothing there. It's just a field. We're not going
to be hurting anything if we did it at our expense and returned the property to
the way it is now when we're finished with it. I can't imagine he's going to
have a problem with that.
Councilman Horn: If you're going to put that shrubery in there, you can blade
up to the barricade from one side and you can blade up to the shrubery from the
other side but the rest of it's going to be filled with snow. How is that
going to be an access in the winter?
Bill Engelhardt: We're talking about a 10 foot walkway in here. You'll have
to come in and take that 10 feet out. Clean that out.
Councilman Horn: Before you could get a firetruck through you'd have to come
and plow it.
Bill Engelhardt: No, when he plows snow, when he gets done plowing your
cul-de-sac out, then come in and take that out with a front end loader or
something.
Gary Warren: We go around on our second pass so to speak and we dress up areas
that we know are problem areas such as cul-de-sacs and this would be just
another one put on the list. Clean out, as Bill said, with a front end loader
or bobcat for example would be very useful in that type of a situation.
Bill Engelhardt: I think Gary, you do that with hydrants too. Don't you go
out and clean around hydrants so it would be the same piece of equipment that
you'd be cleaning around hydrants.
C[7'
Councilman Horn: Explain to me again what you're going to put in that area. I
thought you were going to put something in there so it wouldn't like a through
section.

City Council Meeting - March 28, 1988
Bill Engelhardt: The Centex proposal was to, you can leave this blank too.
' You wouldn't have to put any landscaping in there but it would seem to me I
guess, a good idea too that if we would dress that corner up a little bit so it
wasn't all weeds and who's going to take care of it? We don't want to go out
' there and have to cut that little piece of grass. I suppose you could pave it.
That's one option to pave the whole thing but it would appear that it would be
more attractive as you came into this cul-de-sac area, to give the appearance
that it wasn't a through road. If you pave it and you put all the blacktop in
' there and the barriers, somebody down the line is going to say, that's a
right-of-way and you're going to start getting petitions to utilize it as a
right-of-way.
' Councilman Horn: How are you going to have something that you can landscape
that you can plow through?
' Bill Engelhardt: You aren't going to plow through the sides. You're just
going to scoop the snow off to get a 10 foot strip just like you would clean
around the hydrants. Go in with a front end loader and pull your snow back to
' make the 10 foot strip.
Councilman Horn: Is that a city street then? City maintained street?
IGary Warren: Yes.
Councilman Horn: It isn't now?
II Gary Warren: No.
Councilman Boyt: I want this barricade to work. To me, for it to work, one of
the things we have to do is we're not building a permanent barricade here but
at some point, maybe it's 20 years from now, land is going to develop on the
other side of these big parcels and when it does, the conception is that that
' road is going to go through. I think we need to make it pretty clear that
someday that road is going to go through because if we hide it, then I can
assure you that we're going to get a tremendous petition the day that we decide
' to open it up. So I'd like to see the area that you've got shaded there,
paved. I would even support a sign there that said this is a temporary
barricade. I want the barricade there because I don't want the traffic but I
' don't want to mislead anybody into thinking that it's going to be closed
forever.
John Speakes: I'm with Centex Homes. If we take that barricade, if you think
' of the barricade on the diagonal across that road instead of perpendicular, the
snowplows are going to go by one side.
Gary Warren: We can work out the details during the plans and specs phase so
you'll have another chance to look at it then. Obviously it needs some more
thought here to get it to that point.
Kevin Clark: I also am with Centex Homes. In anticipating some of the
questions that would come up tonight, I spoke with the Natoli's and mentioned
to them that basically what we have is a situation of a deadend and there would
be some backing up of city vehicles and such. I proposed to them that Centex

City Council Meeting - March 28, 1988 '
would improve a 10 foot apron so that in essence, we would deed it over to the
City to have an area to back up into and you're not backing up into a rutted
area. What we wanted to do was put in an improved apron on the Natoli
1111
property. I had talked to than before the meeting so there's a place to
properly back up in.
Councilman Geving: I think it's important though, if we do this with the '
driveway at the Natoli's, the Natoli's may not always live on that property
over the next few years until that is developed. I would hope that we would
have some kind of an agreement with the Natoli's that is binding on the future
homeowners as well.
Mayor Hamilton: We'll get an easement.
Councilman Geeing: Okay, we'll get the easement necessary to do that because I
can see that as a potential future problem. I did talk to the Natoli's and
they are more than willing to use their land.
Bill Engelhardt: After listening to discussion, if we took -that 10 foot strip
and made it 22 and just carried it all the way through, that would solve it.
Mayor Hamilton: Seeing how Mr. Natoli is here, I'll ask him. Everybody has
been telling us that you agreed that we may be able to back our trucks up
during plowing to use a part of your property so they can turn around. Would
you be agreeable to an easement so we could do that?
Mr. Natoli: Perfectly alright.
Bruce Cameron: I just had a question about Teton Lane. There has been talk at
one time that Centex was going to purchase that and deed it over to the city.
Is that the case?
Mayor Hamilton: That's what is being accomplished here, right.
Bruce Cameron: So at some point in time the property owners could be assessed
if that street was put through there and brought up to the city standards?
Gary Warren: If it was brought up to full city standards. '
Councilman Geving: Potentially.
Mayor Hamilton: Yes, full city standards. Someday.
Councilman Boyt: I think we should follow up on this gentleman's comment that,
were you here two weeks ago when we discussed this?
Bruce Cameron: No I wasn't.
Councilman Boyt: The plan is to not upgrade this road until that property is
developed over there at which time there would be a much' larger group of people
that would be assessed for it.
Bruce Cameron: Thank you. I was in the hospital.

City Council Meeting - March 28, 1988
1 Jim Donovan: I'm just wondering, were you saying that you're not going to
assess it until the property develops? Like my property would be developed.
You wouldn't be doing any assessing until that time? '
' Mayor Hamilton: That's correct. Could I ask you a question too Jim? I'm
sorry, I didn't see you come in. We had talked again about the availability of
' having our trucks when they're plowing, turn around at the end of that street.
I was wondering if you would be amendable also to just a "T" at the end of the
street so the truck could pull in there and back up and turn around. If we
could get an easement from you and develop it at our own expense?
' Jim Donovan: Yes.
' Councilman Horn: I'd like to finish my question. You were saying we would •
have a 2 inch bituminous coating on this?
Bill Engelhardt: That's right.
' Councilman Horn: Similar to a driveway?
Bill Engelhardt: That's correct.
Councilman Horn: Do you know what garbage trucks can do to a driveway? How
long do you expect that to last?
II
Bill Engelhardt: I really don't have a problem with it. With a 2 inch mat
with a base that's constructed properly. We talked about that last week. It's
I _ the base that creates or doesn't create a problem and if that's constructed
properly, I don't think the 2 inches will have a problem. You find in the city
streets that 2 inches is almost the standard section.
Councilman Horn: The other thing I read in here is that everything we put in
now will come out when it's brought up to city standard so there will be no
benefit in what we're doing now to a final street?
' Bill Engelhardt: That's correct.
' Councilman Horn: It seems kind of a waste. Is there anyway we could do
something that would be more permanent at a later date?
' Gary Warren: The reason that that statement is true is because of the work
that would be done with the utilities and normally we run the utilities down
the center of the road in that easement area so by the time you get done
excavating the trenches for the utilities, you've basically destroyed the
' subbase and you have to come back and rebuild that. That's the reason why we
couldn't take advantage of what we're putting in now.
Councilman Horn: And you couldn't go besides it or make some provision for
that now?
Gary Warren: The utilities?
It
Councilman Horn: Yes.

City Council Meeting - March 28, 1988
Gary Warren: We try to be creative and if we've got some existing condition
that is worth salvaging, Church Road for example where we're looking at the
south end of Church Road, even though we've got the Metropolitan Commission is
going to be installing our full road section out there, the Carlson property is
going to be putting in the sanitary sewer on the west side outside of our road
section so we don't have to bust up that road section. So we do, if the
situation dictates it, we will try to be creative and put our utilities in
other areas. I think in this case, it all depends on how the development goes
and we'll certainly keep that in mind.
Councilman Horn: I really have trouble with this. What it all boils down to
is we're doing all this just for a potential secondary access requirement at
some point. The City is going to have to plow a section of street now that it
didn't have to plow. We're going to have to put in a chunk of pavement that is
totally temporary. I really question the benefit of this whole thing based on
this. Now if there could be something of a permanent nature for a future plan
I could see it but I really have to question this.
Mayor Hamilton: Wouldn't you be able to salvage the Class V out of there?
Gary Warren: Yes, you're not going to totally lose it but it gets contaminated '
as a result. We did, in the downtown here for example, we salvaged a lot of
material there so those things are feasible. It's just a matter of what the
proposed improvements would be and how you could justify the salvaging of them. '
Councilman Geving: Centex Homes are here tonight. Is there someone here who
can speak for the corporation? Do you agree with the recommendation in the
Council's packet tonight that you would pay for not only the street but the
expanded scope of the Alternate #4 study?
Kevin Clark: I can't say I agree totally but I'd like to get beyond this.
Councilman Geving: That's good enough for me.
Resolution - '
#88 25: Mayor Hamilton moved, Councilman Geving seconded to approve
the Teton Lane Feasibility Study Alternate #4, Curry Farm Subdivision Phase 2,
File #87-16 with the recommendation that the expense for implementation of this
alternate study be borne solely by Centex Homes. It is further recommended
that the developer be responsible for reimbursing the City for it's
consultant's expenses in preparation of this study, namely $3,700.00. Further, �• '
that design details for the upgrade of Teton Lane in accordance with the
criteria laid out in Alternate #4 shall be submitted for approval to the City
Engineer and the City Council as a part of the plans and specifications
approval process for Curry Farms Second Addition. All voted in favor except
Councilman Horn who opposed and motion carried.
APPROVAL OF PLUMBING/HEATING INSPECTOR IN CONJUNCTION WITH HEATING PERMIT AND
FEE SCHEDULE.
U4 Mayor Hamilton: This was an item we looked at last week and I had asked then
't s� Council to table it until such time as we had an opportunity to review the
,iP total staffing needs within the City. I think I've asked for that about a
