RES is providing stream restoration credits to Prince George’s County Maryland Clean Water Partnership (CWP) program. The CWP is a Public-Private Partnership formed to meet the US Environmental Protection Agency’s (EPA) Clean Water regulatory requirements. The projects delivered through this contract will be enrolled as part of Prince George’s County Bay TMDL Action Plan, with the associated nutrient reductions credited toward compliance with the Bay TMDL. RES designed and constructed four projects totaling 27,294 LF of restored channel throughout the County. These four projects generate approximately 568 Impervious Acre Credits for Prince George’s County. 

To execute these projects, RES performed existing site assessments and geomorphic surveys. Using this data and Natural Channel Design philosophies and published reference data, RES designed bankfull channels that provided stable banks and frequent floodplain connectivity. Additionally, RES ensured that there were no offsite floodplain rises and performed all necessary hydrologic and hydraulic modeling. RES acquired all state, federal and local permits necessary to execute the proposed work.  

Upon completing the design and permitting a portion of the projects, RES’ construction staff used a team of subcontractors and in-house construction crews to execute the projects. During construction, RES’ design staff remained an integral part of the team, making frequent site visits, attending multiple site meetings, and ensuring the proper execution of the design.
