FIRST CREEK TRIBUTARIES UPSTREAM OF I-70
MASTER DRAINAGEWAY PLAN
URBAN DRAINAGE AND FLOOD CONTROL DISTRICT, CITY OF AURORA & SOUTHEAST METRO STORMWATER AUTHORITY
First Creek, an east bank tributary to the South Platte River, originates upstream of Interstate 70 and E470 and generally flows to the northwest. The area upstream of I-70 has been studied several times, but the tributaries to First Creek have not been studied in detail. This study focuses on the tributaries to First Creek upstream of I-70 that have tributary drainage basins greater than 130 acres. The study area encompasses approximately 8.1 square miles and is located within the City of Aurora and unincorporated Arapahoe County. The study is also located within the limits of the Urban Drainage and Flood Control District boundary. The watershed is currently mostly agricultural or open space with some multi-family residential development. Development is anticipated to increase in this area. The change from mostly undeveloped to more urbanized will have a significant effect on the drainage systems within the study area.
The purpose of this project is to provide HYDROLOGIC ANALYSIS and to develop alternatives and recommendations for STORMWATER INFRASTRUCTURE IMPROVEMENTS that will be needed as development occurs.
KEY PROJECT GOALS
• Clearly define intent of stormwater improvement goals and objectives for future implementation.
• Inform, guide, and provide expectations to manage development effects on stormwater quality, drainageway stabilization, flood risk, etc.
• Integrate proposed improvements with realistic location of future trails, open space, traffic master plans, and development planning.
• Define stream management corridors to provide stormwater conveyance.
• Develop guidance for future vegetation and provide reference for roughness coefficients for maintenance purposes.
