FY26-DDOT-IPMA-Four Subwatershed GI Retrofit

The District of Columbia Department of Transportation is forecasting a contract for the design of green infrastructure retrofits across four subwatersheds in FY26. This initiative aims to enhance stormwater management and environmental sustainability through targeted ecological upgrades in urban areas, aligning with broader water quality and resilience goals. The work will involve comprehensive planning and engineering design to integrate nature-based solutions such as bioswales, rain gardens, permeable pavements, and tree plantings into existing transportation and municipal infrastructure. While the solicitation has not yet been issued and no specific set-aside, NAICS code, or point of contact details are available, the project is expected to require expertise in civil engineering, environmental design, and urban hydrology. Performance will focus on the District of Columbia, with implementation likely concentrated in targeted subwatershed areas identified for improved stormwater control. Contractors will need to coordinate with municipal agencies and community stakeholders to ensure designs are functional, equitable, and compliant with local environmental regulations. The forecast was posted on July 23, 2026, and interested parties should monitor the official contract portal for the formal solicitation.
