Project Location: Ellicott City, MD

Problem: During major storm events, an Ellicott City neighborhood located along Hunter Road experienced significant flooding. The stormwater drained into the city’s historic district, and the flooding was exacerbated by the uphill funneling of runoff into the community and Main Street located downstream. Private residential neighborhoods were seeking solutions to help manage the stormwater runoff, and the Howard County government responded by making projects easier and more affordable.

Project Location: Lancaster, PA

Project Location: Chevy Chase, MD

Problem: Stormwater runoff from Woodend, a 40-acre nature sanctuary in Chevy Chase, MD that serves as headquarters of the Audubon Naturalist Society, was impacting neighboring property and adding to pollution in nearby Rock Creek. Design challenges included the site’s historic registration, steep slope and existing mature trees.

Project Location: Baltimore City, MD

Project Location: Baltimore City, MD

Problem: The 30-acre MedStar Harbor Hospital campus sits on the banks of the Patapsco River adjacent to a public recreational trail in a hyper-urban setting with impervious surfaces covering 18 acres. Every year roughly 20 million gallons of stormwater runoff is discharged directly into the river adding to pollutant totals and water quality issues.

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: Baltimore County, MD

Problem: Open space areas within the Miramar Landing neighborhood were bare, compacted dirt lots that conveyed untreated runoff to local streams and were eyesores for the community. The impervious surfaces within this development also transported polluted runoff into the Middle River, which has historically been plagued with harmful algae blooms and fish kills.

Project Location: Westminster, MD

Project Location: Westminster, MD

Problem: This recreational pond could not maintain an acceptable water level during dry periods with the water level dropping very low. This prevented nearby residents from taking part in recreational activities and wildlife appreciation. While renovating the facility, the county took the opportunity to treat millions of gallons of runoff from surrounding suburbs.

Project Location: Town of New Windsor, MD

Problem: The detention basin at the Blue Ridge Manor facility in the Town of New Windsor was constructed in the early 1990s during the time when stormwater management focused more on flood control than water quality. Erosion at the outfall, overgrown vegetation, trash, and steep slopes surrounding the basin led to this facility being retrofitted in the fall of 2017.
