Wetland Delineation for South St. Paul Property

Carlson McCain was retained to identify and delineate wetland and aquatic resources on the South St. Paul Rod and Gun Club property, as part of a proposed Frattalone Companies project to expand the existing berms and construct new berms on the property.

Before fieldwork began, Carlson McCain scientists reviewed historic aerials, soil survey, topographic, National Wetland Inventory (NWI), and Public Waters Inventory (PWI) maps for the Property. This existing resource information was used to assist in identifying and delineating wetlands and drainage features within the property.

The field wetland delineation was then conducted, following the U.S. Army Corps of Engineers (USACE) 1987 Wetland Delineation Manual and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: North Central and Northeast Region (Version 2.0) (Manual).

Carlson McCain’s fieldwork identified the presence and delineated the acreage of wetlands within the property boundary. All wetland areas were documented with paired upland and wetland observation points. Soils, vegetation, hydrology, and landscape indicators were evaluated along the wetland edge to accurately delineate the wetland boundaries. Evaluated boundaries of delineated wetlands were recorded with a Trimble R-10-2 GPS receiver for sub-foot accuracy.

Four areas on the property met the criteria of hydrology, hydric soils, and hydrophytic vegetation to be classified as wetlands. Their boundaries were flagged for the survey and confirmed by the Dakota County Soil and Water Conservation District, which serves as the Local Governmental Unit (LGU) administering the Wetland Conservation Act (WCA) in this area of Minnesota.
