• 261 -270 total units • Density of 4.3 to 4.4 units per acre The primary difference between the two plans is the configuration of Street B. SITE CHARACTERISTICS Soils Soils are heavier types with low infiltration ability and higher runoff rates. Land Cover Ground -story vegetation is planted crops and wetland Species Rare and Unique Resources This area is outside the Anoka County sand plain area where we have concerns for rare plant species. There are no other known rare species concerns on this property. Tree Preservation There are a few scattered trees on the borders of the property and a stand of pines on the SE side. None of the trees appear to be significant. Wetlands It appears a preliminary wetland delineation has been performed. There has been no technical evaluation of the wetland quality or boundaries. A Wetland Preservation Corridor in the Resources Management Plan is mapped in the SE corner. Wetlands to the south of the property may preclude extension of Street D. It may be beneficial to consider looping Street D back to the north (Street C). Opportunities may exist for restoration of the ditch and adjacent wetlands to create wetland bank credits and off set on site impacts. Surface Water Management A ditch runs through the southern part of the property. Surface water from most of this site flows to Clearwater Creek. A small portion goes to Amelia Lake. A Natural Resources Conservation Corridor (Greenway Corridor) from the Resources Management Plan is mapped along the ditch in the SE corner. The site includes floodplain in the southeast corner. No elevation information has been determined. This will need to be defined with the project design. • • •
