Project Location: Lancaster, PA

Problem: The portions of Santo Domingo Creek that flowed through New Street Park, a community park in Lititz Borough, were severely degraded. The straightened stream banks were steep and eroded, and the channel cut down deep into legacy sediment. Flooding was a frequent problem in the adjoining, heavily populated areas.

Project Location: Lancaster, PA

Problem: Big Spring Run, a headwater tributary of the Conestoga River, was characterized by severe streambank erosion and degradation. The stream valley had been filled in by nutrient-rich sediments generated by historical land-use practices, including 19th century milldams located along the stream. Streambank erosion was contributing to over 60 percent of the sediments suspended in the stream flow. The release of nutrient-rich sediments was impacting downstream water quality.

Project Location: Warwick Township, PA

Problem: The Lititz Run channel flowing through the Banta property in Warwick Township had been moved, straightened, and dammed for a historical mill operation. This artificial configuration created streambank erosion and stream channel instability. The overly wide and deep channel was migrating slowly into the side of a steep slope with a major road artery 75 feet above.

Project Location: Annapolis, MD

Problem: This Annapolis dealership was covered with impermeable asphalt and concrete. Without any greenery, there were drainage issues, including flooding, puddling, and nearby erosion. In addition, polluted runoff was draining into local Spa Creek.

Project location: Lititz, PA

Project location: District of Columbia

Problem:  For twenty years, a prime 20-acre parcel of land in DC sat undeveloped due to concerns about being able to effectively manage stormwater runoff.  The parcel is located atop a steep hill, adjacent to the Anacostia river, in a gateway area of DC.

Project location: Mount Airy, MD

Problem: St. James Episcopal Church in Carroll County was suffering from significant erosion during storm events.  This posed not only aesthetic and water quality challenges; it also created a safety hazard for students at an adjacent daycare.

Project location: Annapolis, MD

Problem:  Winchester on the Severn is a residential neighborhood north of Annapolis.  In one section of the community, an old stormwater conveyance system was failing, with water flows scouring the nearby hillside and polluted runoff impairing Chase Creek, a tributary of the Severn River. 

Project location: Annapolis, MD

Problem: Visitors to Maryland’s historic state capital often stop at the Annapolis Visitor Center before exploring the rest of the city.  Unfortunately, the Center’s parking lot was poorly accessible, unattractive, and prone to flooding (or becoming iced-over in winter).
