Home My WebLink About008 Streets, Roads, and GradesGran Cielo Subdivision Phase 3 Preliminary Plat Application 8 - Streets, Roads, and Grades The required information related to streets, roads, and grades is provided in this section. All proposed roadways within the subdivision are classified as local streets or alleys and are designed within a standard 60-foot-wide public right-of-way for local streets and 30-foot right- of-way for alleys. The Roadway Exhibit included in this section outlines the location of the proposed roadway in relation to the proposed public right-of-way easements and identifies existing and proposed street names as well as intersection locations. The Roadway Detail drawing is included in this section showing a typical cross-section of the proposed local roads and alleys. Additionally provided is a preliminary plan and profile of the proposed improvements to South 27th Avenue along the project frontage including a cross-sectional detail.
