Northeast Park Stormwater Management (SWM) Pond is within the Rock Creek watershed and was originally constructed in 1973 as part of the Redgate Farm Pond cluster. In 2005, the facility was converted into an extended detention pond to collect and slow stormwater runoff and reduce water pollution from a 51.07-acre drainage area. Over half of this area (26.59 acres) is impervious surfaces such as asphalt, concrete and buildings.
The extended detention pond has successfully collected sediment and pollutants from stormwater runoff and reduced the impact to local waterways. Despite regular dredging over the past five years, a recent inspection of Northeast Park Stormwater Managment Pond identified a 91 percent loss of capacity due to sedimentation. In order for the area to continue functioning properly, sediment removal, maintenance and other improvements are needed to restore the treatment capacity of the facility.
The upstream channel will be stabilized and restored to reduce downstream sediment loading to the pond. End-of-road treatments are also proposed at Neal Drive and Wesley Road to intercept concentrated flow upstream of the SWM pond and provide additional water quality treatment.
Increase the depth of the pond to improve stormwater quality treatment.
Provide floodplain reconnection for the upstream channel.
Feature high and low marsh wetland areas that will provide habitat for native faunal species.
Comprehensive non-native and invasive plant control and management strategy.
Address erosion at the end of at Neal Drive and Wesley Road.
