Consider Wetland Mitigation by Dan
Bowman
Issue
In order to construct the roads in the plat of Ridgewood Hills, it is necessary
to fill 1.71 acres of type 2 wetlands. There is a site plan attached showing
the location of the areas to be filled. That site plan also shows the location of
the 3.42 acres of wetland (at a ratio of 2 to 1) that will need to be created to
replace the wetland filled.
The City of Elk River is the Local Unit of Government (LGU) responsible for
reviewing this type of request for compliance with the Wetland Conservation
Act (WCA). The City's Technical Evaluation Panel reviewed this request.
This panel is made up of a representative from the State Board of Soil and
Water Resources, Sherburne Soil and Water Conservation District, City
Engineer Terry Maurer, and Stephen Rohlf.
We concluded that the request is in compliance with the WCA and offer the
following findings:
· The developer has minimized the impact on the wetlands as much as he
could by modifying his plat (moving the road as far south as possible).
· The developer tried to avoid impacting the wetlands by trying to gain
access to his property from adjacent property.
· Not being able to fill wetland would mean not being able to access the
property, which would constitute a hardship.
Recommendation
The Technical Panel is recommending that the Council approves the wetland
mitigation plan for Mr. Bowman with the following conditions:
That this approval is subject to obtaining the necessary permit from
the Army Corps of Engineers.

o
That the letter of credit for the improvements in the plat also covers
the cost of the replacement wetlands for one year after the City
approves their construction and that the developer agreement reflects
this.
o
That the replacement wetlands are protected by having a restrictive
covenant recorded.
o
That the bottom of the culvert for the proposed road in the location of
former Judicial Ditch #1 is at the approximate level of the existing
wetlands so they are not drained.
That the slopes of the replacement wetlands are a maximum to 4 to 1
for safety and no materials excavated from any wetland can be placed
back into a wetland.
o
That the developer provides the City with a status report on the
replacement wetlands one year after they are created.
