<br />PROPOSAL FOR <br />Adoption <br /> <br />7. Recommended Improvement Plan <br /> <br />Note <br /> <br />The following chapter represents the proposed update to the recommended im- <br />provement plan outlined in Chapter 7 of the Tri.Valley Transportation Plan/Action <br />Plan, <br /> <br />The following chapter has been edited to respond to obvious changes that have DC. <br />curred over the last five years and to address new issues that have arisen since the <br />Plan was adopted in 1995. Recommended changes are shown in redline-strikeout <br />(annat. <br /> <br />Based on the results of the alternatives testing, the TAC and the TVTe decided to focus the <br />ultimate improvement plan on the arterial corridors within Tri-Yalley rather than the Tri- <br />Valley gateways. The plan must address the primary question: What can we do to achieve <br />, the best level of service within the Tri-Valley? <br /> <br />Three contributing factors influence the ability to respond to this question: <br /> <br />1. Financial constraints <br /> <br />2. Physical limitations within corridors <br /> <br />3. Development patterns <br /> <br />Financial resources for all projects are limited. The Measure C and Measure B sales tax <br />programs provide substantial funding for specific projects in Tri-Valley. Other projects <br />must compete for the relatively small pot of public funds. Developer fees, which have an <br />upper limit. could help supplement public funds. Future sales tax or gasoline tax initiatives <br />may Ot may not be successful. <br /> <br />Expansion of major corridors within Tri-Valley is limited due to existing development and <br />terrain. These limitations hinder the development of transportation corridors other than <br />the existing 1-680 and 1-580 corridors. <br /> <br />Development patterns within Tri-Valley have been geared toward relatively low housing <br />and commercial densities. These patterns are expected to continue in the future. This de- <br /> <br />18 April 2000 <br /> <br />Page 13 <br />
