The Point of Rocks Stream Restoration and Pond Removal Capital Improvement Project was conceived to address widespread channel erosion and habitat degradation along approximately 4,900 linear feet of stream and outfall channel.
This project also provides TMDL and impervious acre credit towards Frederick County’s Phase 1 MS4 permit obligations. Phase 1 of the project, constructed in 2019 restored approximately 3,700 linear feet of stream and floodplain using a combination of restoration techniques including natural channel design and regenerative step pools.
Phase 2, scheduled for construction in 2021, will address an additional 1,200 feet of stream and outfall channel and remove an existing in-line stormwater management pond. Removal of the pond and its embankment will eliminate embankment hazard and restore longitudinal connectivity to the stream.
Straughan played a key role in the negotiation of permit phasing to allow the county to secure MS4 credit for the upstream portion of the project on schedule while the more complex permitting for the pond decommissioning continued in parallel. Straughan provided design, permitting, and construction inspection services and was responsible for management of subconsultants.
