Hydrology and Stormwater Management Analysis

The contract entails a comprehensive hydrology and stormwater management analysis to assess surface and groundwater impacts, flood risk, drainage patterns, and the capacity of existing stormwater infrastructure in support of CEQA compliance for a project located in El Dorado Hills, California, with a ZIP code of 95762. The scope requires detailed evaluation of hydrologic and hydraulic conditions to determine potential environmental effects and ensure that stormwater systems can handle design storm events without exacerbating flooding or degrading water quality. Analysis must align with state and local regulatory requirements to support environmental review processes and inform mitigation measures. This subcontract, classified under NAICS code 541620 for environmental consulting services, is issued by the El Dorado Hills Community Services District and is tied to a CEQA-related project identified by the number 2026070665. The work must provide technical documentation and assessments that demonstrate compliance with environmental thresholds and help determine whether a mitigated negative declaration or environmental impact report is warranted. The results will be critical for permitting, land use decisions, and infrastructure planning within the jurisdiction, requiring expertise in hydrologic modeling, floodplain mapping, and stormwater management design standards applicable to California’s regulatory framework.
