Englewood advances Zone 2 water redundancy and La Panne drainage design
Englewood City of, Colorado · Meeting date: October 19, 2026 · Published: October 20, 2026
Englewood City Council has approved a $371,639 design agreement for a combined water and stormwater project near the Allen Water Treatment Plant. The work is intended to reduce reliance on a single Zone 2 transmission main and develop a solution for recurring drainage issues around La Panne.
Key points
- Council approved the Zone 2 Water Connection Redundancy and La Panne Stormwater Improvements design agreement.
- The agreement with JMT totals $371,639, with a staff-managed 10% contingency of $37,164, for total authorization of $408,803.
- The water component will design a parallel supply route for Zone 2, which is currently served by a single 24-inch steel transmission main dating from the 1950s.
- The stormwater component will investigate drainage improvements at a La Panne low point where runoff currently moves between two houses into City Ditch.
- The Water and Sewer Board recommended approval at its October 13 meeting.
Full report
Englewood City Council has authorized design of a combined water-redundancy and stormwater-drainage project intended to address two infrastructure vulnerabilities near the Allen Water Treatment Plant.
The approved agreement with JMT is valued at $371,639, comprising $227,000 for the water element and $143,000 for stormwater work. Council also authorized a 10% staff-managed contingency of $37,164, bringing the total project authorization to $408,803.
The water project will examine a redundant connection for Zone 2, which is supplied from the Allen Water Treatment Plant to the Sherman Zone 2 tank through a single 24-inch steel transmission main built in the 1950s. Utilities staff said the main, which runs through Bellevue, is the sole feed to the zone. A major break could therefore affect the city’s ability to maintain expected water service pressure.
The proposed redundant main would connect to the existing transmission main and run east along Chenango to Broadway, creating a parallel supply route. The design scope includes geotechnical investigation, subsurface utility investigation, detailed design and phased construction implementation planning.
The same procurement will assess a longstanding drainage issue on La Panne. Runoff from a low point on the street east of La Panne currently enters a small private-property storm sewer, reaches La Panne, then flows between two houses into City Ditch. Staff said a nearby resident had reported flooding reaching the property foundation during heavy rain.
The design will consider a storm-drain system intended to move as much runoff as practicable south toward Big Dry Creek, while retaining the City Ditch overflow function for larger events. Staff said the combined delivery approach could create economies of scale by coordinating water and stormwater construction in one area.
The Water and Sewer Board recommended the agreement on October 13. Construction would follow the design phase, which staff estimated would take about a year.
