Weir Gulch

Weir Gulch is one of the three waterways being studied as part of the Denver Urban Waterways Restoration Study. The study sponsors include the United States Army Corps of Engineers (USACE), the Urban Drainage and Flood Control District (UDFCD), and the City and County of Denver (CCD). The study area for extends from Sheridan Boulevard west to the South Platte River. The condition of Weir Gulch varies between an open channel, concrete channel, and underground in pipes. The study will identify cost-effective plans to restore habitat and ecological function, reduce flood risks, and improve recreation.

Weir Gulch Study Key Goals

  • Primary Goal:  Reduce flood risk
  • Secondary Goal: Restore ecosystem habitat
  • Complementary Goal: Improve access to recreation and provide environmental education opportunities

The Denver Urban Waterways Restoration Study will develop an understanding of existing conditions, evaluate a broad range of options, and select a preferred plan based on benefits and costs.

The study began in early 2015.

Study Updates

The study team has completed three rounds of public meetings for the Feasibility Study. In Fall 2015, we gathered information about existing conditions at the waterways from local businesses, residents, and recreational users. In 2016, the public had the opportunity to review and give feedback on the recommendations for each of the waterways. In 2018, the draft report and recommendations were presented and open for public comment.

The Final Integrated Feasibility Report and Environmental Impact Statement (EIS) was released in April 2019.


Neighborhood Integration Plan

As part of a comprehensive understanding of the waterways, the City and County of Denver is conducting a study to identify neighborhood enhancement opportunities in and around Weir Gulch. Neighborhood enhancement opportunities include trail connections, improved access areas, additional neighborhood connections to the Gulch, and recreation activity opportunities. Outcomes of the study will be incorporated into the preferred plan developed as part of the Denver Urban Waterways Restoration Study.

The materials from the most recent Integration Plan meeting have been updated to include a summary of the meeting discussion and revise example graphics to clarify draft elements.

Feedback Boards and sample ideas (PDF)
Revised to remove draft markings in certain areas; no impacts to individual parcels have been determined and will not be known until a project is funded and well into engineering design.

This document was presented at the Integration Plan Public Meeting for Weir Gulch on August 30, 2016, and has been edited to incorporate comments during that meeting and to clarify draft elements of the graphic examples.

  • Pages 1-4: Gray hatching removed to clarify that impacts to properties are not yet known
  • These boards were created to include potential amenities in the Army Corps study. This is not a design. The final design process will not begin until funding is secured.

The city encourages all residents to be aware of flood risks and take precautions to protect their lives and property. Learn more at to understand flood risks in your area and get information on what you need to do to stay safe.


Emergency Preparedness

Flood Insurance

Flood Insurance Information from official NFIP/FEMA website:

Until a new floodplain is adopted by FEMA, Preferred Risk Policies (PRP) are available in areas outside the Special Flood Hazard Area (SFHA) as currently shown on FEMA published Flood Insurance Rate Maps (FIRMs). FEMA SFHAs are shown as Zone A, AE, AH, AO, etc… on the FIRM. Areas outside the SFHA are designated as Zone X. Below are links to information on Flood Insurance Rates:

City & County of Denver Floodplain Ordinance (see Chapter 4)



Additional floodplain study

The UDFCD is currently assisting the City of Denver by conducting a floodplain study for Weir Gulch and its tributaries.  A floodplain study is referred by floodplain administrative officials as a Flood Hazard Area Delineation study (FHAD).  The result of a FHAD study will identify and update the flood risk potential and floodplain boundaries due to both changes that are caused by humans (such as construction for developments) and natural changes that occur over time within a drainage basin of a major waterway like Weir Gulch. The Army Corps of Engineers is using the preliminary results of this study to help inform the Urban Waterways Restoration Feasibility Study’s team to formulate alternatives to reduce the flood risk, as well as identify opportunities for ecosystem restoration, habitat and recreation.
