Sand Creek, an east bank tributary to the South Platte River, has a drainage area of appoximately 181 spuare miles spanning multiple jurisdictions. The study area for this update will encompass 11.8 miles along the stream corridor from the confluence with the South Platte River in Commerce City upstream through the City and County of Denver to Colfax Avenue in the City of Aurora. Several other drainageways flow into Sand Creek through the study area include Toll Gate Creek, and Baranmor Ditch in the City of Aurora; and Westerly Creek in the City of Denver. The Burlington Ditch crosses underneath Sand Creek near the Metro Wastewater Reclamation District in Commerce City. The Sand Creek corridor provides great ammenities such as the Lake Bluff Nature Center, Star K Ranch, and nearly 14 miles of Sand Creek Regional Greenway multi-use trails.

The primary goals for the Sand Creek Major Drainageway Plan and FHAD are to update watershed hydrology downstream of Colfax Avenue and update flood hazard delineations. While adhearing to the District’s vision to promote stream health along natural drainageway function, this study will seek opportunities for softer solutions, promoting ecological function and reducing long term maintenance.
