Executive Summary
<br />
<br /> Transportation Service Objectives
<br />
<br /> A key element of the plan is the list of Tran.~portation Service Objectives. These are
<br /> obiectives that the Tri-Valley cities and counties should use as a guide to making
<br /> trnn-~portation and land use decisions. In Contra Costa County under Measure C, the
<br /> jurisdictions are required to make a good-faith effort to comply with the trnn.portation
<br /> service objectives on mutes of regional signlt~cance or risk the loss of return-to-source
<br /> funds. In Alameda County once the plan is adopted, individual jurisdictions are respousi-
<br /> ble for maintaining Tran-~portation Service Objectives through their general plans. The
<br /> transportation service objectives adopted by the TVTC are as follows:
<br />
<br /> · Maintain Level of Service D (V/C < 0.90) on arterials, and measured at intersections.
<br /> · Maintain level of Service E (V/C < 0.99) on freeways.
<br /> · Maintain Level of Service E conditions on 1-580 for no more than four hours per day
<br /> (except on Altamont Pass) and on 1-680 for no more than eight hours per day.
<br /> · Do not increase capacity for single-occupant vehicles at gateways.
<br /> · Increase average vehicle ridership for commute trips by 10 percent.
<br /> · Increase the transit mode share through providing express transit travel times that
<br /> are competitive with autos.
<br />
<br /> The TVTP is not intended to be a land use control doc-ment, such as a General Plan.
<br /> While the plan is based on a set of growth assumptions, the plan should not be interpret-
<br /> ed as limiting growth to the ass-reed levels. Nevertheless, the plan does establish
<br /> Transportation Service Objectives, which may indirectly influence growth rates. Growth
<br /> beyond what is assumed herein may occur provided the TSOs are met. r, ........ ~., ;r

<br /> violations, in a Tri-Valley jurisdiction, then that jurisdiction can either (a) implement
<br /> transportation improvements (e.g., road widening) to correct the TSO defldency on that
<br /> affected network segment, or (b) implement other measures intended to result in measur-
<br /> able improvements to TS0s on the Routes of Regional Significance network and contrib-
<br /> ute to significant improvements in air quality. Failing this~ the jurisdiction can refer the
<br /> problem to the TVTC for ioint resolution. In the event that the TVTC cannot resolve the
<br /> violation to the mutual satisfaction of all members, the jurisdiction may modify the TSO
<br /> standard, but only if other jurisdictions are not physically impacted.
<br />
<br /> Action Plans in Contra Costa County are required to include the following components:
<br />
<br /> · Long-range assumptions regarding future land use based on local General Plans.
<br />
<br /> · Procedure for review of impacts resulting from proposed local General Plan amend-
<br /> ments that have the potential to influence the effectiveness of adopted Action Plans.
