MEMORANDUM TO: Mayor & City Council FROM: Rebecca Haug, Environmental Technician DATE: June 16, 2004 SUBJECT: Wetland Conservation Act Decision- Trout Brook Estates WCA 04-05 Proposal - The developer of Trout Brook Estates is proposing to fill 83,073 sq ft of Type 1, 2, and 3 wetlands for construction of public streets through the project, a stormwater pond and small portions of lots. The Technical Evaluation Panel (TEP) for the City of Elk River reviewed the proposal and found both the filling and replacement plan acceptable. The replacement plan consists of 84,000 sq ft of New Wetland Credit and 84,000 sq ft of Upland buffer. The new wetland will be created adjacent to the existing wetland on the site. A map showing the filling and replacement is attached to this memo. The TEP looked at this plat several times and worked with the developer to reduce the amount of wetland impacts. There are a number of shallow excavated channels on this property that will be filled. Since these channels have been disturbed, reed canary grass (an invasive wetland species) has taken over and the TEP determined that the wetland replacement would provide improved wetland functions and values by replacing the reed canary grass with native species. The developer also reduced and/or removed lots to avoid wetland impacts. The sizes of some building pads were reduced, a boardwalk was placed across a wetland, and retaining walls were used to reduce the impacts. FINDINGS Pioneer Engineering prepared a Wetland Replacement Plan Application for the property dated April 1, 2004. The Technical Evaluation Panel reviewed the replacement plan on April 8, 2004 and May 5, 2004. Combined notification of the proposed filling and replacement plan was mailed out to the appropriate govermrtental agencies on April 5, 2004.
