About this file
This is a technical specification document for the City of Wheat Ridge, Colorado Department of Public Works Engineering Division, detailing traffic calming improvements on Benton Street between 40th and 41st Avenues as part of the 2025 Neighborhood Traffic Management Program (NTMP). The project scope includes the installation of one new concrete speed hump constructed per City Detail C-F02, featuring colored concrete in Davis Tile Red with a stamped English Slate pattern, along with advance warning pavement markings and signage. The speed hump installation incorporates specific construction details including sawcut and sealed joints at 4'-6" on-center depths of 3", tooled joints at 2'-0" on-center (2'-3" east-west), epoxy-coated rebar reinforcement, and extends across the full street width with 1:12 slope transitions on each side. Additional work includes installation of advance warning markings per Detail S-M01 utilizing white thermoplastic Type I paint, a modified W17-1 speed bump sign (30"x30"), and a W13-1P advisory speed sign reading "15 MPH" (18"x18"). A double yellow centerline is also to be installed on Ames Street pending changes in traffic flow resulting from the Benton Street calming project.
The document references compliance with Colorado Department of Transportation (CDOT) Section 627 guidelines, pavement marking standards, the Manual on Uniform Traffic Control Devices (MUTCD) 11th Edition Section 3B-30, and ITE Guidelines for Speed Humps and Speed Tables. The speed hump widths may vary depending on installation location and available clearances, with final specifications to be field-verified. The subgrade is required to be compacted to minimum density per soil classification per CDOT Section 203.07. The plan notation indicates that specific concrete sections and locations are subject to field identification by Wheat Ridge representatives, with work potentially extending beyond the mapped area. No pricing information, contract term, bid dates, or award information is provided in this technical specifications document.
