TO: Don Ashworth, City Manager
FROM: Phillip Elkin, Water Resource Coordinator
DATE: March 25, 1996
SUBJ: The Woods At Longacres 3rd Addition
Wetland Alteration Permit 93 -5 - 1
BACKGROUND
The wetlands are located along Galpin
Woods at Longacres development (see
existing Ag -Urban wetlands, found ift
City trail along Galpin Boulevard T1-
one ratio in accordance to the Wetland
management plan.
Boulevard (CR at the Third Addition of the
Figure 1). Th"'project would fill 0.13 acres of
wo basins, to provide adequate space for a future
e wetlands would be replaced on -site at a two to
Conservation Act and the City's surface water
conditions of final plat approval for The Woods development ,Since these wetland
impacts primarily benefit the City, the City has agreed to process the alteration permits.
WETLAND IMPACTS
Figure 2 shows the impact area and replacement plan of wetlands F and G. The plan
shows that wetland F which is .06 acres will be filled bordering Galpin Boulevard and a
new detention pond will be created in the remaining area. Wetland G will have 0.07
acres filled on its east border. This wetland is connected to a storm water culvert along
Galpin Boulevard which drains west to a larger wetland basin. The area on the west edge

of wetland G will be expanded to accommodate 0.14 acres of the mitigation. This '
wetland will continue to function with the culvert draining to the east. The remainder of
the mitigation (0.05 acres) will be completed as part of a park near wetland A, in the
future development of Longacres. '
ANALYSIS
'
Staff has reviewed this lan and has found that it meets the requirements of both the
p q
City's Surface Water Management Plan and the Wetland Conservation Act. The
replacement of wetland loss will be provided at a ratio of 2:1. The wetland impacts will
'
be necessary to construct the city trail on the east side of Galpm Boulevard. Construction
at this time will allow the mitigation to occur on site, rather than waiting for future
impacts when this land will be unavailable. The mitigation of this site will be completed
along with the remaining wetland mitigation and storm pond construction at the Woods
development.
'
UPDATE
'
On April 3, 1996, the Planning Commission unanimously voted to approve the wetland
alteration permit. This vote followed a brief discussion on the projected timeline for trail
construction in this area. The City has received a nationwide permit GP -17 -MN from the
,
Army Corps of Engineers authorizing the project. On April 24, 1996 the 30 day
comment period will end and a decision on approval or denial will be made by City of
Chanhassen, in accordance to the Wetland Conservation Act. There have been no
comments to date and the City does not anticipate objections to a project of this size.
RECOMMENDATION
Staff recommends the City Council adopt the following motion:
'
"The City Council approves Wetland Alteration Permit 95 -4 for The Woods at Longacres
3rd Addition subject to the following conditions:
1. Wetland Conservation Act and the City of Chanhassen Surface Water
Management Plan requirements.
'
2. General Permit 17 under the Army Corps of Engineers is applicable and should be
completed by the City.
'
3. The City shall develop a sediment and erosion control plan in accordance with the
City's Best Management Practice Handbook. Type III erosion control fencing
'
will be required around the existing wetlands."

Planning Commission Meeting - April 3, 1996
Mancino: Thank you. This is open for a public hearing. Anyone wishing to address the
Planning Commission.
Maureen Farrell: Actually I was just, my name is Maureen Farrell and I'm a resident in this
area and actually.
Mancino: Could you give us your address please?
Maureen Farrell: Yes. 7336 Fawn Hill Road. And actually I'm interested in finding out
what the overall plan is. I see this as a section of the bike path, but is this to connect onto
TH 5 and how far north is it to go and... interested in finding out.
Mancino: Okay.
Aanenson: Phil's going to quickly run and get the trail plan map. Just so you know, it's tied
into the updating of Galpin Road. Right now it is under the jurisdiction of the County. It's
possible that it be turned over to the city in the future. Depending on whether it's upgraded at
urban section. What type of cross section it would be and at what time it's upgraded is when
the trail will be built. So at this time it's on our master trail system. It will connect down to
TH 5 and all the way up north but it's not on a specific time table yet, but we are making
provisions for it to happen.
Mancino: And it usually happens as development comes in. As each subdivision comes in,
then that part of the trail is continued.
Aanenson: But not with this segment because we're not sure exactly what the section of this
road will look like. Again because we're not sure, it's under the County's jurisdiction and
we're not sure at this point. There's talk that with the TH 101 turn back, that maybe this will
be given back to the City and it may have a different design standard than maybe the County
would give it. So that would mean whether or not it would be at grade, which would be
similar to other trails that are like maybe Kerber Boulevard or it'd be separated. Maybe
benched in to, benched in a little bit off separated so there's different design techniques.
What we're trying to do now is acquire the right -of -way. Actual right -of -way width.
Maureen Farrell: So as this part of the development goes in, it doesn't necessarily mean that
the bike path will come in...
Aanenson: That's correct, right.

Planning Commission Meeting - April 3, 1996
' Maureen Farrell: Is there any, I mean is there a point where you say it needs to be done or is
it really just open ended? ...time frame at all.
' Aanenson: Again it goes back to when the negotiations with the County, because it is a
County road and normally it's tied in to when Galpin be improved as a whole and widened at
a future date. They would do that as a part of that project. Similar as they're doing Powers
' Boulevard and Lyman. Those projects are being done by the County and then the
improvements are being put down. You mentioned Lake Susan has been down there a long
time without trails and that's being done now as Powers is being widened. So it's kind of
' done as an overall improvement project.
Mancino: So the County would want to give us back the highway so we could keep it up,
' right?
Aanenson: If they give TH 101, yeah they may give it. It's part of the discussion.
' Mancino: Okay. But there's no question the City has a master plan to, as Kate said.
' Aanenson: It's highly desirable for this trail to connect, certainly. But it's not going to
happen as a part of this.
' Maureen Farrell: Okay. I guess my concern is that it is going to be a very large
development and you have a sizeable development across the road and right now with the
' grade school just down, and the community center, I am concerned with how narrow that road
it and there's no place for children and bikes presently. So my concern would be that that is
part of the game plan in deciding when that does become effective... thank you.
' Mancino: You're welcome. There will also, there may be in the fall a referendum the city
will have to create and to build more trails and one of them would be on Galpin and it would
' be hopefully connecting to the Bluff Creek Elementary School.
Maureen Farrell: Thank you.
' Mancino: So we all may be voting on that soon. Anyone else wishing to address the
Planning Commission? Seeing none, may I have a motion to close the public hearing and a
second please.
Fwmakes moved, Mehl seconded to close the public hewing. The public hearing was closed.
' Mancino: Thank you. Comments from commissioners. Craig.
