25-087 - El Paso County Stormwater Master Drainage Plan

El Paso County desires to update its drainage master planning to include appropriate levels of long-term hydrologic and hydraulic analyses and public infrastructure capacity evaluation throughout the County. Currently there exists many drainage basin planning studies (DBPSs) for developing areas within the County, with an additional DBPS anticipated to begin in late 2025. The majority of existing County DBPSs were completed prior to 2010, and are therefore outdated and obsolete in many aspects, including realized development types and densities, design criteria, hydrologic modeling, compliance with water quality and water rights regulations, and observed development impacts on drainage facilities and streams. Individual jurisdictions and districts within the County have had additional studies completed that overlap with unincorporated County areas and may have recommendations inconsistent with County DBPSs. The Stormwater Master Drainage Plan (SWMDP) study will analyze existing and future regional drainage conditions; identify flood hazards, deficient facilities and corrective improvements; identify anticipated future capacity improvements, priorities, and estimated costs for input into the County’s capital improvement program (CIP); and evaluate the general status of the current drainage and bridge fee system based on anticipated future improvement needs.
