39 <br /> <br />volume on Foothill Road was reduced by approximately 2,000 vehicles <br />a day. He added that the City should recognize that people will <br />drive through Foothill Road as a pleasant alternative to the <br />freeway and that Foothill Road should be designed to accommodate <br />through traffic in addition to local access, left turns and <br />deceleration. <br /> <br /> Mr. Tarver inquired how long the two-lane road would be <br />functional before four lanes would be needed and how much that <br />transition would cost. He further inquired if the interim solution <br />would require the construction of soundwalls, and if so, where they <br />would be needed and how much they would cost. <br /> <br /> Mr. Elliott replied that the transition from two lanes to four <br />lanes would cost between $8 Million and $10 Million, excluding the <br />cost of property acquisition. He added that soundwalls have been <br />built on the east side of Foothill Road, from Stoneridge Drive to <br />Foothill High School, and that soundwalls may not be necessary on <br />the west side. <br /> <br /> Mr. Swift stated that all the projects that have been recently <br />approved have been designed either with larger setbacks so that the <br />front yards would face the road or with the rear yards buffered by <br />the houses instead of soundwalls. He pointed out that an increase <br />in the noise level would depend not so much on the width of the <br />road as on the traffic volume. He added that by itself, the <br />development along the west side of Foothill Road would not create <br />the need for four lanes; it would take additional traffic coming <br />from the general build-out of the City, particularly the <br />office/commercial development on Stoneridge and throughout the <br />City, as well as the development of the San Francisco Water <br />Department property. <br /> <br /> Ms. Mohr inquired if sound is impacted by the movement of <br />traffic. <br /> <br /> Mr. Swift replied that a free-flowing road generally has a <br />higher noise level than one that is congested to a point where <br />traffic moves at a slower speed. He added that congestion usually <br />occurs only for one to two hours during the day and would have no <br />basic impact on noise. <br /> <br /> Mr. Butler indicated that he supported the interim solution <br />with a provision for the right-of-way for elements in the General <br />Plan. He then asked staff to describe the transition of the <br />northbound and southbound through traffic lanes along the Kliment <br />property. <br /> <br /> - 5 - <br /> 2-19-91 <br /> <br /> <br />
