Saefern

Annapolis, MD This design/build project was requested by the Saefern Community Association and completed in 2009. A steep slope located beside the community marina parking lot displayed significant erosion which discharged high volumes of polluted stormwater and sediment into Clements Creek, a tributary of the Severn River. Through the Chesapeake Bay Trust Stewards Program, a Regenerative Stream Channel system (RSC) […]

Arlington Echo

Millersville, MD This design/build project, completed in 2009, is a living shoreline which stabilizes 250 linear feet of deteriorating bulkheads. Approximately 6,000 square feet of tidal wetlands and 250 linear feet of shoreline were created.This living shoreline project is one of many environmental projects at this site which as a whole serve as a living […]
