Drainage Improvement Projects


 Douglas County takes COVID-19 seriously and will ensure our contractors follow appropriate health and safety practices as recommended by the Association of General Contractors (AGC) and Colorado Contractors Association (CCA)


Mile High Flood District (MHFD)
MHFD has partnered with 41 local governments to master plan drainage improvements through the Denver Metro area; design, construct and maintain stream corridors including removal of trash and debris; provide flood warning services, and develop resources related to improving water quality in our streams.  The program leverages local government dollars to fund stream projects that reduce flood risk and provide community amenities.  The 2021 work plan includes the following Douglas County projects:

  • Newlin Gulch at Recreation Drive

Highlands Ranch Drainage Projects:  In Highlands Ranch alone, there are approximately 500,000 feet of pipe in existing stormwater systems and cross culverts.  The Douglas County Storm Sewer Video Program has already completed videos of half of these locations, and the next half will be accomplished within the next couple of years.  Staff began repairing these pipes over the last five years and over 10,000 feet have already been repaired or will be repaired by the end of 2020.  The sizes of these pipes vary from 15-inch to 126-inch, and repairs will be ongoing as the aging infrastructure required.

For further information on culvert repair projects please contact Engineering at 3030-660-7490 or Shawn Dankenbring, Project Manager.

Repair and Replacement locations identified for 2020:

  • Greenland Road culvert replacement
  • Patterson Road culvert replacement
  • Roundup Road culvert replacement

Pinery Drainage Project:  

Phase 1 – The Pinery Water & Sanitation District replaced water mains within certain roadways in the Pinery to repair roadside drainage issues.  The County provided funding for additional survey, design, and construction needed to include the drainage fixes in the District’s project.  Construction began mid-January 2020 and was completed in May 2020.

Phase 2  is a Developmental Phase for the Pinery Systemic Drainage Repair Program. Staff will work with property owners to develop feasible solutions to the drainage issues. Public outreach and property owner education about the importance of maintaining drainage infrastructure will be included in this phase.
