CLIENT: Harford County Department of Public Works
Prime: BayLand Consultants & Designers, Inc.
Construction Cost: $5,000,000
Foster Branch is a tributary to the Gunpowder River in Harford County, Maryland. The tidal portion of the waterway has been dredged four times in the past 30 years with over 35,000 cubic yards of sediment being removed. Aquatic habitat, as well as, recreational boating access continues to be lost. After dredging in 2010, Harford County Department of Public Works (DPW) hired BayLand to conduct a sediment abatement study which included identifying and evaluating sediment sources, identifying opportunities to implement retrofits, developing design concepts and cost estimates and preparing a Small Watershed Action Plan (SWAP) for the 1,400-acre watershed. The purpose of the study was to prepare a plan to reduce sedimentation to Foster Branch, to minimize the amount of dredging and tidal water impacts, and to serve as a SWAP to obtain Environmental Protection Agency (EPA) Section 319 restoration grants.
