<br />7. Updated Re.commended Improvement Plan <br /> <br />widemngs and extensions are necessary to serve new development, so the plan calls for di. <br />rect developer construction or at least funding. The primary issue is how to share costs <br />between jurisdictions having joint responsibility for a particular road. This is discussed <br />further in the Financing Plan chapter. <br /> <br />There are twO major arterials in the Tri~Valley that do not provide direct access to planned <br />development but rather serve interregional traffic between Alameda County and Contra <br />Costa County. These two arterials are Crow Canyon Road and Vasco Road. <br /> <br />Crow Canyon Road The portion of Crow Canyon Road west of Bollinger Canyon Road is a <br />two-lane rural road that lies within the jurisdiction of Alameda County and Contra Costa <br />County. While once used by its adjacent residents [0 bring goods to the market, today <br />Crow Canyon Road is being used by commuters as an alternate to the 1.580/1-680 free- <br />ways. Development in the vicinity of Crow Canyon Road, especially in the fast-growing <br />San Ramon Valley area, has generated a significant increase in traffic on this roadway. The <br />expected forecast for this roadway is LOS F. <br /> <br />The roadway, which is a narrow and windini road, was not designed to handle commuter <br />traffic and does not have adequate width~lignment. Alameda County, in collaboration <br />with Contra Costa County and the City of San Ramon, prepared and developed a project <br />study report, pursuant to California Senate Bill 1149. The report recommended the con~ <br />struction of eight-foot shoulders, climbing lanes, and road realignment eliminating short~ <br />tadii curves. <br /> <br />Contra Costa County has in its Measure C program the improvement of Crow Canyon <br />Road within Contra Costa County. Alameda County, however, is seeking for funds to im~ <br />prove the two-lane section of the roadway. Unfortunately, improvement of this portion of <br />Crow Canyon Road cannot be directed to a particular developer construction. But since <br />the traffic forecast clearly indicates that traffic increase on this roadway is development~ <br />related, it is recommended that subregional transportation impact fees be used to improve <br />the section of Crow Canyon Road wirhin the Tri~Valley. <br /> <br />Vasco Road Vasco Road is a narrow and winding rural road that is a major commuter and <br />truck route linking the Tri-Valley with eastern Contra Costa County. Approximately 17 <br />miles of Vasco Road, starting at a point on Vasco Road approximately one-half mile south <br />of the county line to the intersection of Camino Diablo in Contra Costa County, has been <br />relocated as a result of the construction of the Los Vaqueros Reservoir. This portion of Va- <br />sco Road is designed to Sta.te and County standards. The remaining section of the roadway <br />in Alameda County (approximately three miles in length) needs to be upgraded to these <br />standards as well to improve traffic flow and safety. Alameda County is currently seeking <br />funds to improve the section of the roadway from the new Vasco Road to the Livermore <br />City limit. This proposed improvement includes realignment of the roadway, widening of <br /> <br />18 April 2000 <br /> <br />Page 19 <br />
