Highlands Ranch Small Storm Sewer UV-CIPP Lining Project
The Highlands Ranch Small Storm Sewer UV-CIPP Lining projects have started for 2025– Pipe repairs have already been completed located on Plaza Drive (Broadway & Ridgeline) and on Broadway (south of Northridge Recreation Center driveway). Starting in mid-August to early September of 2025, the next phase of storm sewer maintenance on Sterling Ct, Sterling Dr, Heatherwood Ct, Broadway just south of the Northridge Rec Center Access point, and at 9261 S Broadway, will occur. These projects are anticipated to be completed on December 31, 2025, weather dependent (see map of the area of these locations above or in “Photos” section below).
Storm Pipe Video Inspections
The 2024-2025 Highlands Ranch subdivision Storm Sewer Pipe Video Inspection Program is ongoing (started in mid-March 2024) and we will be adding 43,500 linear feet (approx. 325 sections) of storm sewer to be inspected. In Highlands Ranch alone, there are approximately 500,000 feet of pipe in existing stormwater systems and cross culverts. The Douglas County Storm Sewer Pipe Video Program began over six years ago, has already completed videos on more than half of these locations, and the remaining locations will continue to be worked on over the next few years.
