The Weaver Creek Drainageway watershed encompasses approximately 7.2 square miles and is located in Jefferson County and the City of Lakewood. Click on the "Study Area Map" button to view the project limits. The watershed is mostly residential and open space. The Weaver Creek Drainageway originates west of the Willow Springs subdivision, west of C-470, and south of Highway 285. The existing drainageway is approximately 8 miles long. It flows in an easterly and northeasterly direction until its confluence with Bear Creek, northwest of the intersection of Kipling Avenue and Dartmouth Avenue. The purpose of the project is to provide hydrologic analysis, develop alternatives and recommendations for stormwater infrastructure improvements where problems are predicted. The Major Drainageway Plan (MDP) included all of these items. The project also included a floodplain analysis, which was documented in the Flood Hazard Area Delineation (FHAD). A previous FHAD was completed for Weaver Creek in May 1981. An MDP has not previously been completed for Weaver Creek.

Key Project tasks included the following:

  • Develop hydrology that reflects both the existing and the future land use elements
  • Identify existing flooding and conveyance issues
  • Develop drainage improvement alternatives
  • Hold a public open house to discuss the project and findings
  • Preliminary design of the selected alternative
  • Delineate the floodplain along Weaver Creek

 

Some of the existing stormwater infrastructure is undersized. Spills occur during major storm events in some areas. The MDP identified these issues and provided solutions. As some areas further develop or roadway improvements are made, the information from this study will be used to guide the project sponsors in constructing appropriate infrastructure.
