BACKGROUND
1 As a part of road improvements for County Road 17, Powers Boulevard. The upland fringe
of an existing Class A wetland will be impacted. This wetland was developed as part of the
I mitigation for the Lake Drive project completed in 1989. The original wetland mitigation
for the Lake Drive project was required to be 4.5 acres but was developed with 4.9 acres
of wetland. This road project will result in removal of .01 acre of wetland fringe.
1 ANALYSIS
I The city is proposing to upgrade County Road 17, Powers Boulevard. This project includes
the reconstruction and widening of County Road 17 from Highway 5 to a point
approximately 400 feet south. The proposed roadway reconstruction and widening is
necessary to serve current and future traffic levels along Co. Rd. 17, Powers Boulevard. The
widening is necessary to serve current and future traffic levels along this road.
1 Approximately 440 cubic yards of clean granular fill will be placed within the .01 acre area
of the wetland. The wetland boundary had been identified at approximately the 888 foot
contour. The city will replace the .01 acre of wetland as the surcharge area of Lake Drive
I is being removed and the side slope is regraded. The size of the wetland will remain 4.9
acres, with the 0.1 acres being mitigated from the west side, to the north side of the wetland
I (see attached map).
Permits are being sought from the DNR for the extension of the Riley Creek culvert under
I County Road 17 and the Army Corps of Engineers (nationwide) for the minor impact to this
mitigation pond.
I Type III erosion control should be installed between the existing wetland and all disturbed
areas. The erosion control fence shall be removed once the pond has been re- established
with vegetation.
1 PLANNING COMMISSION UPDATE
I The Planning Commission recommended approval of the wetland alteration permit, at their
May 6, 1992 meeting, with the conditions outlined in the staff report.
1 STAFF RECOMMENDATION

Re: Wetland Alteration Permit for County Road 17
' Reconstruction - City Project No. 90 -04.
Dear JoAnn:
' Attached is the wetland alteration permit application that
is required for the City's County Road 17 reconstruction
project. The wetland being impacted was created in 1989 --
I as mitigation for Lake Drive wetland impacts.
The as -built mitigation pond for Lake Drive is slightly
Planning larger than it was required to be. The mitigation
Transportation requirement was 4.5 acres and the existing is 4.9 acres.
Engineering Therefore, the area impacted by County Road - 17
Urban Design improvements will not reduce or affect the previous
' mitigation agreements. Additionally, on the north edge of
the existing •mitigation pond, an area of Lake Drive
Thresher Square surcharge will be removed and result in the creation of an
700 Third Street So. additional +0.05 acres of wetland.
I Minneapolis,
MN55415 Permits are also being sought from the DNR for the
612/370 -0700 extension of the Riley Creek culvert under County Road 17
I Fax612/370 -1378 and the Army Corps of Engineers (nationwide) for the minor
impact to this mitigation pond. We will keep you informed
Minneapolis on the status of these permits.
I Phoenix
Denver Please, include the review of this application on your May
Orlando 6, 1992 Planning Commission agenda and the May 18, 1992
' San Diego City Council agenda.

Batzli: The public hearing is closed. Comments. Suggestions. Joan.
Ahrens: Is muck the same as topsoil?
Aanenson: It's a landscape term.
Ahrens: Is that a term of ours? 1
Aanenson: Yes. Trade term.
Ahrens: I don't have any more questions.
Batzli: Jeff. Steve. Ladd, anything?
Conrad: No. I like it. I like how the city handled this.
Batzli: Okay, thank you. Tim. I don't have any questions other than to I
just ask the general question of, if we constructed this within the last
couple of years, why the heck didn't we know there was going to be curb and
gutter going in there? Why do we have to do it now, just out of idle
curiousity?
Aanenson: Dave may speak to why that segment was left out of the original II
improvements.
Batzli: Was this just kind of an oversight the first time we did this?
Hempel: I think the scope of the project back then was not realized.
Future expansion of Powers wasn't looked at to be all honest.
Batzli: Yeah, okay. Is there a motion?
Ledvina: I would like to make a motion recommending that the Planning
Commission approve the Wetland Alteration Permit #92 -5 as shown on the
plans dated April 6, 1992 with the 3 staff conditions.
Conrad: Second.
Ledvina moved, Conrad seconded that the Planning Commission recommend

2. Type III erosion control shall be installed between the existing
