DISCUSSION:
The City of Littleton owns and maintains approximately 53.5 miles of storm sewer infrastructure. In 2018, the city televised all 53 miles of storm sewer, but it was not analyzed until the 2024 storm sewer master plan. Upon review of all the video, it was determined that 23% or 17 miles of the network had a high or very-high risk score of failure. Staff identified 8 high-priority projects that have the largest consequence of failure. Two projects (Belleview & Federal and Prince & Ridge) were completed in 2025, and one additional project (Broadway at Lee Gulch) is currently under construction. A 4th project at Ridge and Elati was originally slated for 2025 repairs but was moved to 2026 due to staff availability and funding.
The intersection of West Ridge Road and South Elati Street is a high traffic area due to the proximity of Heritage High School and Runyan Elementary School, furthermore Ridge Road serves as a major roadway connection to South Broadway. With the proximity to the schools, staff anticipated completing a maintenance repair project in Summer 2026. Insituform Technologies, LLC D/B/A C&L Water Solutions was selected as the contractor through the city oncall contract services in the Spring of 2026. City project 25-71 was awarded to clean, closed-circuit televise (CCTV) and rehab approximately 1100 LF of 18” corrugated metal pipe (CMP).
In late June 2026, a segment of pipe failed south of South Sundown Circle creating a sinkhole in the bike lane and sidewalk. The CCTV inspection was complete and identified 8 additional segments of collapsed or damaged storm sewer at imminent risk of failure. Given the existing collapse and imminent failure risk, it was determined there was a threat to public property, health, and safety; and a subsequent emergency repair contract was requested. C&L Water Solutions was selected for the emergency repair, as they were already engaged on the related Project #25-71 work on Elati and were able to mobilize quickly.
Per Section 102 of the Littleton City Charter, City Council may waive competitive bidding provisions in cases of emergency affecting public property, health, peace, or safety, and Resolution No. 138-2014 grants the City Manager authority to execute emergency procurements under these circumstances. Mike Gent, as acting City Manager in Jim's absence, approved the emergency contract procurement on July 2, 2026. Upon his return, City Manager James Becklenberg, further approved the emergency contract price of $476,458.00, funded by Storm Sewer Enterprise Fund (4200).
As work begun, it was determined that additional pipe needed to be fully excavated. The sinkhole was initially anticipated to be approximately 20 ft in length. Upon excavation, the pipe had failed a total of 283 linear feet. This caused additional delays in both time and costs.
Work commenced on July 20, 2026, with school scheduled to begin on August 11, 2026 it left crews only 3 weeks to complete all the repairs. There was some additional work at the manhole at Ridge and Elati that was delayed until the fall break October 15-19, 2026. The contract will need a 60-day extension to accommodate additional work needed.
BACKGROUND:
Aging storm sewer along West Ridge Road and South Elati Street were previously identified as a high priority repair project. A contract for cleaning, CCTV and rehab approximately 1100 linear feet (LF) of storm sewer was awarded to contractor C&L Water Solutions in April 2026. Due to proximity of school route, repair work was held until summer break in June 2026. In June 2026, a segment of storm sewer collapsed causing a sinkhole in the sidewalk and adjacent bike lane. C&L Water Solutions were able to get the crew out to clean and televise the lines, as per the original April contracts. At that time, 8 additional repairs were identified as imminent collapse in addition to the sinkhole.
In compliance with City of Littleton emergency procurement procedures, an emergency repair contract was issued for 9-point repairs along the 1100 LF storm sewer, including the 8 newly identified point repair at risk of collapse and a 20 foot segment of collapsed storm sewer. As the lining material had already been purchased, it was determined the most economical approach would be to install new CMP and complete the lining project once the repair work was completed.
During construction, the collapsed segment of pipe was found to be 283 LF instead of 20 LF. Full repairs were completed to get the road and sidewalk open prior to school commencement in August. The additional 263 LF of collapsing pipe extended under sidewalks, bike lane and through the intersection of South Sundown Circle. Additionally, pipe bedding material was also brought in to stabilize the area around the pipe that had washed out from beneath the storm sewer. Additional time and materials totaled $175,427.96.
A portion of the project at the intersection of Ridge and Elati was delayed until the Littleton Public School fall break in October. The contract will be extended an additional 60 days to finish the repairs at the intersection of Ridge and Elati.

FISCAL IMPACTS:
The existing emergency construction contract with Insituform Technologies, LLC D/B/A C&L Water Solutions for the Storm Repairs Elati South of Ridge Project is $476,458.00. This project will be funded by the Storm Drainage Utility Enterprise Fund.
Pursuant to the City’s Procurement Policy, all contracts exceeding $500,000 must be approved by City Council.
STAFF RECOMMENDATION:
Staff recommends approval of the construction contract.
ALTERNATIVES:
If the construction contract is not approved, the project will not proceed at this time. This will have an adverse impact on the property owners whose septic systems are at the end of their useful life and are planning to connect to the new sanitary sewer as soon as feasible.
