Highlands Ranch Drainage Projects

Project Update

Updated March 15, 2023:

  • The 2023 Highlands Ranch subdivision stormwater pipe video inspection program has started (see map of the area of these locations above or in “Photos” section below).
  • Starting in mid-March 2023, JBS Pipeline (Contractor) is currently performing video inspection on the existing pipes from Wildcat Reserve Parkway (from Highlands Ranch Parkway to Broadway up to Lucent Boulevard).
  • Construction crews will continue (2022 – 2023) to work on the UV lining of culverts within Highlands Ranch.
  • The large and small culvert projects from 2022 are finishing up, and we are working on starting our 2023 projects.
  • Outfall Cleanings have been ongoing in Marcy Gulch, Spring Gulch, and Dad Clark Gulch. Big Dry Creek and Willow Creek outfall cleanings are starting again in 2023 (from work previously completed in 2022).


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 six years and over 15,000 feet of storm sewer was repaired by the end of 2022 (2023 data coming soon!).  The sizes of these pipes vary from 15-inch to 126-inch, and repairs will be ongoing as the aging drainage infrastructure required.
