Exhibit M2-Functional Roadway Classification
Functional Roadway Classification-Printable and Zoomable
The Functional Roadway Classification Plan shows the hierarchy of our roadway system, consistent with the guidelines of the Federal Highway Administration:
- Freeway: Freeways are limited-access, high-speed travelways included in the state and federal highway systems.
- Other Principal Arterials: Other Principal Arterials serve the major centers and corridors of activity, carry the highest volumes of traffic, and serve the longest trips of all City roadways. Other Principal Arterials typically accommodate four to eight lanes of traffic and medians.
- Minor Arterials: Minor arterials accommodate less traffic and are for trips of moderate length. Minor Arterials allow a greater level of access to abutting properties so speeds are lower than Other Principal Arterials. Minor Arterials connect our community but ideally should not penetrate residential neighborhoods. The roadway configuration and right-of-way width vary depending on local conditions, but typically accommodate four to six lanes of traffic and medians.
- Collector Streets: Collector streets provide access to abutting properties and traffic circulation within residential neighborhoods and business areas. Collector streets allow access to local and arterial roadways. The roadway configuration and right-of-way width vary depending on local conditions, but typically accommodate two to four lanes of traffic.
- Local Streets: The primary function of a local street is to provide direct access to abutting properties. Local streets rarely have more than two travel lanes, speed limits are generally low, and are not intended for through traffic. Local streets are not included on the Functional Roadway Classifications map because they are not considered part of the backbone circulation system identified in this element.
- Enhanced Intersection: Enhanced Intersections may include additional lanes, reduced median width, increased right-of-way width, removal of on-street bike lanes, or reduction of parkway width to increase capacity, improve operations and respond to local demands. Detailed engineering studies are necessary to identify the most effective and feasible types of improvements.
The ultimate number of lanes needed on each roadway, as well as the right-of-way requirements, are identified in the City’s Master Plan of Street and Highways.
