RE: Potential Wetland Impacts for the Lake Susan/Rice Marsh Lake Water Quality Improvement Projects
Dear Mr. Obermeyer:
This letter serves as BWSR's official determination ofwetJand impacts related to the Lake Susan and Rice
Marsh Lake Water Quality Improvement Projects. According to draft project plans presented by Mark
Wilson and Bob Obermeyer of Barr Engineering, the District is proposing to treat stormwater runoff by
increasing dead storage via bemls and excavation within wetlands. The Minnesota Wetland Conservation
Act (WCA) Rules Chapter 8420.0105 "Scope" section, states"... This chapter regulates excavation...in all
wetland types if excavation includes filling or draining or results in conversion to nonwetland."
In addition, according to the WCA definition of "project", "...A project may not be split into components or
phases for the sole purpose of gaining additional exemptions."
Therefore this project as proposed on the attached sheets would require sequencing and full 2:1 mitigation
for all combined fill and excavation activities within the wetland boundary above the Ordinary High Water
Mark (or for combined activities in their entirety if DNR categorically waives jurisdiction to WCA). Please
feel free to contact me with additional questions.
