This document is a Colorado Department of Transportation (CDOT) Standard Plan for Curb, Gutters, and Sidewalks (Standard Plan No. M-609-1), issued by the Project Development Branch on July 4, 2012. The comprehensive technical drawing provides detailed design specifications for multiple types of concrete curbs, gutters, sidewalks, driveway entrances, and related infrastructure components. The standard plan includes four detailed sheets with multiple cross-sectional views, isometric diagrams, and specific construction notes for various curb and gutter configurations, including Type 2, Type 4 (Key-Way), Type 6, and different driveway entrance types with varying sidewalk and pavement interfaces.

The technical specifications outline precise dimensional requirements, slope specifications, expansion joint details, and construction guidelines for concrete infrastructure. Notable technical requirements include concrete class specifications, reinforcement details, maximum slope limitations, and specific instructions for transitional areas between sidewalks, driveways, and roadways. The plan provides standardized design parameters for municipal and transportation engineering projects, ensuring consistent construction methods and quality across different infrastructure developments. The document includes specific notes about drainage structures, traffic signal equipment, and other potential infrastructural considerations, providing comprehensive guidance for civil engineering and construction professionals.
