Welsh Park Stormwater Management Pond

Purpose: This project funds the design and construction of a new SWM facility upstream of the pedestrian bridge at the lower end of Welsh Park near Lynch Street. This SWM facility, which was recommended in the Watts Branch Watershed Study, will provide full channel protection storage and partial water quality storage for the 53-acre drainage area. The SWM facility is proposed to be an extended detention dry pond with a micropool and forebay of 3-4 feet in depth, which will enhance and expand the existing onsite wetlands. Staff will work closely with the community in the concept-refinement phase to assess project modifications that reduce the impact on the forest, and active and passive recreational areas. The focus will be to select a design and location that will provide sufficient stormwater control to arrest the active stream erosion, while minimizing the impact on the community’s access to useable open space and minimizing tree loss. In addition, implementing this watershed improvement project supports Rockville’s contribution to Maryland’s voluntary C2K initiatives, as well as supports mandatory compliance with NPDES and TMDL requirements.

First Appeared in Rockville's Capital Improvement Program: Fiscal Year 2002.
