Soltesz is currently supporting Montgomery County in fulfilling the requirements of the Municipal Separate Storm Sewer System (MS4) permitting needs. Under this contract, Soltesz is overseeing two projects securing a total of 174 acre-inches of water quality credit—Avenel TPC Golf Course and B’Nai Israel, where private stormwater management ponds had been constructed providing treatment to large contributing drainage areas. Both ponds were designed per pre-2000 stormwater management criteria and offer opportunities for water quality credits by retrofitting the facilities to meet current standards.

The team retrofitted the irrigation pond at TPC Avenel with an innovative forebay enhancement that will lessen the runoff’s impacts to local streams by filtering out contaminants, recharging the groundwater and protecting against storm surges. Soltesz constructed nearly 1,000 unique environmental site design features that will significantly improve the output from the pond, aiding in the ongoing restoration of our nation’s treasured Chesapeake Bay. The reconstructed pond’s forebay specifically helps by trapping trash and sediment within a pre-treatment area, reducing the cost and frequency of pond maintenance, while increasing the pond’s effectiveness in removing sediment, phosphorus, and nitrogen from entering nearby streams. It will also improve conditions for the aquatic life and provide a longer life cycle to the pond.
