Plan Description - City of Tustin

Chapter 2 • Plan Description
Without the Base, it is likely that connections would have been made
between Tustin Ranch Road and Von Karman Avenue, Valencia
Avenue and Moffett Avenue (this actually exists as an on-base
roadway link) and the east and west sections of Warner Avenue.
• Future Capacity Needs: The Plan creates capacity needs in an area
which has minimal reserve capacity for the future. In essence, the
Plan has to create its own capacity. An effective way of creating
"new" capacity is to provide thru-traffic links across the Plan area.
This has the effect of diverting some non-Plan area traffic from the
adjacent parallel roads, thereby making some capacity available on
those roadways.
2.5.2 Roadways
The roadway plan for the Plan features the key conceptual elements
discussed above: a north-south link (Tustin Ranch Road) and an east-west
link (Warner Avenue), with a unifying internal loop roadway.
A. Typical Roadway Standards
Typical roadway standards for the MCAS-Tustin Reuse Plan
roadway system were developed from the Tustin and Irvine General
Plans and the City of Tustin's "Minimum Design Standards for Public
Works Improvements Constructed Within Public Right-of-Way or
Improvements to be Maintained With Public Funds". Within the City
of Irvine, Irvine roadway standards will apply to both public and
private roads if Irvine chooses to upgrade them to city standards. Six
roadway classifications for the backbone on-site system will be used:
major arterial highway, primary arterial highway, secondary arterial
highway, local collector, local street, and private street. The
following is a brief description of the proposed roadway
classification system that will be used in the Plan. The typical
roadway standards are also shown on Figure 2-4.
1. Major Arterial - Eight Lanes: An eight lane major arterial
has a minimum 144 foot right-of-way and a curb-to-curb
pavement width of 126 feet and includes a median island. The
major arterial carries a significant volume of regional traffic
and does not typically have sidewalks or on-street parking
provisions.
2. Major Arterial - Six Lanes: A six lane major arterial has a
minimum 120-foot right-of-way, a curb-to-curb pavement
width of 102 feet, and includes a landscape median island,
Class II bicycle lanes and sidewalks. Major arterials carry a
