Wolf Creek Master Drainage Plan

Where is Wolf Creek?

Wolf Creek is a northward-flowing stream with source areas in the Platte River-Arkansas River divide area east of the Front Range. It is located approximately 18 miles east of the E-470 corridor. The Wolf Creek watershed, as measured at the Arapahoe County/Adams County line, covers approximately 83.5 square miles. The Master Drainage Plan (MDP) focuses on the portion of the creek and its tributaries within Arapahoe County—approximately 37 square miles.

Why are Master Drainage Plans Important?

Many eastern rural stream beds are dry several months of the year which is why it's important to evaluate how a stream bed will convey flood waters during an event. Studies ensure that as areas develop, structures are built in safe zones. They also identify potential risks for how structures like culverts, bridges and road crossings will support the flow of water. Studies indicate where stream stabilization may be needed to protect natural environments and wildlife habitats.

2020 Final Community Report

The study concluded with the final Master Drainage Plan that will be implemented as development occurs in the Wolf Creek watershed. Currently, the watershed is primarily undeveloped and the MDP will be used to provide guidance for future construction as development occurs. The study identified the 100-year floodplain and analyzed flood-prone areas, drainage problems, stream stabilization and roadway crossing structures. The study assessed degradation along the Creek and identifies areas that may require bank stabilization. An environmental assessment was performed to locate wetlands, riparian areas, and nesting sites.

Timeline & Public Involvement

Public meetings were held late in 2019 and early in 2020. Additionally, a survey was made available to local residents. 

To obtain a full copy of the Master Drainage Plan, submit a request to publicworks@arapahoegov.com. The summary report is linked above. 

Public participation in this process led to great discussions about what the County should prioritize next. We heard from you that Bijou Creek is an area of concern so we are working to identify funding and a timeline to begin that process in the coming years.
