About this file
This is a technical design document for a traffic calming project prepared by the City of Wheat Ridge, Colorado's Department of Public Works Engineering Division. The project, part of the 2025 Neighborhood Traffic Management Program (NTMP), involves the installation of speed humps on Depew Street between 26th and 28th Avenues. The scope of work includes constructing colored concrete speed humps built to City of Wheat Ridge Detail C-F02 specifications, installing advance warning pavement markings, and placing speed hump advisory signs with 15 mph speed limit signs at designated locations along the corridor. The design documents specify that speed humps shall be constructed with Davis Tile Red colored concrete featuring an English slate stamped pattern, with widths varying from 27 to 33 feet depending on location and available clearances. Advance warning markings are to be installed using white thermoplastic Type I paint in accordance with Colorado Department of Transportation guidelines and the Manual on Uniform Traffic Control Devices standards.
The technical specifications detail construction requirements including subgrade compaction, epoxy-coated rebar reinforcement at two-foot centers, sawcut and seal joints at four-foot six-inch spacing, and tooled joints at two-foot and two-foot three-inch spacing. The speed humps are designed with 1:12 side slopes and include specific pavement marking patterns positioned 100 feet in advance of each hump. The document references detail code C-F02 for speed hump construction and detail code S-M01 for advance warning markings, with approval dates of January 2019 and December 24, 2024 respectively. The project is associated with a broader 2026 Residential Concrete Project identified by the City of Wheat Ridge for removal and replacement of concrete infrastructure, primarily residential sidewalks within Improvement Zone 3, with additional work planned outside the shown improvement area.
