Stormwater Master Plan Study Service

The City of Lakewood, Colorado, requires a qualified vendor to perform a comprehensive stormwater master plan study. The agency is seeking to address local drainage concerns, assess existing infrastructure capacity, and identify areas of flooding risk. To solve these issues, the selected contractor must research and collect all necessary data, manage the project files, and coordinate meetings, including an initial project kickoff. The scope of work requires the collection of drainage system GIS shapefiles, record plan drawings, LIDAR surface contours, and documented drainage concerns. The agency requires the development of a comprehensive hydraulic and hydrologic model incorporating a fully dynamic 1D-2D rain-on-mesh and pipe network system. This model must simulate existing system performance under 5-, 10-, 25-, 50-, and 100-year design storm events to evaluate conveyance capacity, surface flooding, and surcharging conditions. The contractor must provide recommended improvements to meet the requirements of the agency's storm drainage manual. Additionally, the project covers the creation of an online digital master plan portal for public access. This task requires expertise in web design, graphic design, ArcGIS Online integration, and data management to build a web experience displaying flooding risk areas. Eligibility is restricted to onshore, USA-based organizations only. The agency requires the performance of the work to be conducted onsite in Lakewood, Colorado. Bidders may submit their proposals digitally via email or through an online portal. The agency is currently looking for proposals to establish the project budget. A pre-bid meeting is scheduled for June 16, 2026. Bidders must submit all questions regarding this opportunity no later than June 23, 2026.
