This is a design manual chapter document prepared for the City of Rio Rancho, New Mexico, in support of the Loma Colorado Boulevard Extension project. The document provides technical guidance and standards for the project design, which encompasses a two-lane roadway extension from Silent Springs Drive to Broadmoor Boulevard, including auxiliary turn lanes, striping, lighting, and signal improvements. The scope includes design specifications for a box culvert to accommodate road crossing over the Arroyo de Los Montoyas and a roundabout at the intersection of Chessman Drive and Silent Springs Drive. This attachment serves as a reference document for design professionals responding to the City's Request for Proposal to establish a design contract through competitive negotiations.

The document establishes engineering design standards and methodologies that selected design firms must follow throughout the project development process. It addresses technical requirements and best practices applicable to the roadway design, drainage structures, and traffic control elements. No specific pricing terms, set-asides, funding amounts, or contract award dates are detailed within this particular attachment, as it functions as a technical reference guide rather than a procurement or financial document.
