About this file
This is a technical specification document for the 2025 Neighborhood Traffic Management Program (NTMP) project on Nelson Street between 38th and 41st Avenue, prepared by the City of Wheat Ridge, Colorado Department of Public Works Engineering Division. The project involves the installation of speed humps with advisory signage along the specified corridor. The speed humps are constructed from colored concrete (Davis Tile Red) with a stamped English slate pattern, measuring 33 feet in width with 1:12 slope sides, and include tooled joints at specified intervals. The design incorporates #4 Grade 60 epoxy-coated rebar spaced at 2-foot on-center intervals, with subgrade compaction to minimum density per CDOT Section 203.07 standards. Supporting signage includes a modified W17-1 sign reading "SPEED HUMPS" (30"x30"), a W13-1P sign displaying "15 MPH" (18"x18"), and a W13-1P sign indicating "NEXT 650FT" (18"x18"). The detailed cross-section and plan views are provided on Sheet 1 of 2, with sign specifications detailed on Sheet 2.
The document includes construction details and specifications approved by the Department of Public Works in January 2019, with updated plan dates of July 16, 2025 and November 14, 2025. The speed hump widths may vary depending on installation location and available clearances, with installation extending to the edge of pavement or gutter lip as applicable. Specific installation locations are referenced on the detailed plans, and all construction must comply with applicable CDOT standards and local city specifications. The project is part of the broader 2026 Residential Concrete Program in Improvement Zone 3, though concrete work locations will be field-identified by Wheat Ridge representatives with potential work extending beyond the mapped area.
