Glenn Estates Pond Enhancement Project

Location: Lanham, MD

Category: Constructed


Glenn Estates is a neighborhood in Lanham, MD. The pond was constructed in 1993 as a wet pond to treat just under the first half inch or “first flush” of stormwater runoff from a 66-acre drainage area.

Soltesz, LLC conducted an in-field survey In November 2017 to evaluate the pond’s existing storage capacity and found much of its original capacity had been lost due to siltation. It was determined that the pond had the potential not just to be restored to its original treatment goals but was a good candidate for a BMP enhancement retrofit. The resulting design proposed to enhance the existing wet pond through adding gabion inflow channels, forebays and other sediment and erosion control, and landscaping to treat 2.6 inches of stormwater runoff from the surrounding areas.

This project is located in the Patuxent River Western Branch watershed in a priority area identified by the Maryland Chesapeake and Atlantic Coastal Bays Trust Fund. The LID Center and the Clean Watershed Partnership  forces to seek construction funds for this project. The general contractor for this project is Kirila Earthworks, and Celsue Construction is the primary subcontractor.

Funding: Prince George’s County and Maryland’s Chesapeake & Atlantic Coastal Bays Trust Fund*
