Murphy Creek and Tributaries Master Drainageway Plan

Mile High Flood District, City of Aurora, Southeast Metro Stormwater Authority, and Arapahoe County

Project Background

The Murphy Creek watershed project area consists of approximately 12.7 square miles located in the City of Aurora and portions of unincorporated Arapahoe County. Murphy Creek is a south bank tributary of Sand Creek that generally flows north and northwest. Spanning multiple jurisdictions, the watershed is home to the Buckley Space Force Base, Arapahoe County Fairgrounds, Denver Area Disposal Site (DADS), many residential, commercial, and industrial developments, and open space parcels. Although the mainstem of Murphy Creek has been previously studied, the tributaries have not been studied in detail.

Project Goals

The purpose of this project is to provide a master plan for Murphy Creek and its tributaries which will serve as a planning document as the watershed is further developed. The purpose of this study is to provide and up-to-date hydrologic analysis and to develop alternatives and recommendations for stormwater infrastructure improvements that will be needed as development occurs.

Key Project Goals

Update hydrology within the watershed

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.

Develop guidance for future vegetation and provide reference for roughness coefficients for maintenance purposes.
