Crain Stream Restoration
- Prince George's County
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. The Crain site restored 4,695LF of degraded stream channel.
To execute this project RES performed existing site assessments and geomorphic surveys. Using this data along with Natural Channel Design philosophies and published reference data RES designed a bankfull channel 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 completion of the design and permitting, RES’ construction staff used a team of subcontractors and in-house construction crews to execute the project. Construction began in August 2020 and was substantially complete by February 2021. 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.
