According to the A_noka County Soil Sut-v'ey, produced by the United States Department of Agriculture's Soil Conservation Sero,fire, rl~e dominant soil series at tine Site consists of the Nymore Series (consisting of foamy coarse sands and loamy sands). The Nymore series consists of nearly level ~o steep, excessively drained soils ~bcmed in out'wash sands. Permeabilky [n this series Ps rapid, and the available water capacity and organic-matter content are tow. The supply of available nitrogen and potassium is tow, and phosphorus medium.

"The Ponds" proposed development plan includes a variety of methods to deal with both ~he rate and quatiw of storm water runoff. Stormwater mitigation efforts include: The development plans caP1 fbr d'~e construction of ~our storm water infiltration ponds.
