<br />Williams Street and Marina Boulevard; Spur trails between the Bay Trail and nearby San Leandro <br />neighborhoods. " <br /> <br />Construction activities associated with the proposed bridge and trail, including truck traffic and <br />heavy equipment use, could affect public access to the existing park facilities; however, these <br />activities would be temporary in nature. See discussion under Section XV Transportation/Traffic, <br />below. <br /> <br />XV. TRANSPORTATlON/TRAFFIC -- Would the <br />project: <br />a) Cause an increase in traffic which is substantial in <br />relation to the existing traffic load and capacity of the <br />street system (Le., result in a substantial increase in <br />either the number of vehicle trips, the volume to <br />capacity ratio on roads, or congestion at intersections)? <br />b) Exceed, either individually or cumulatively, a level of <br />service standard established by the county congestion <br />management agency for designated roads or highways? <br /> <br />c) Result in a change in air traffic patterns, including <br />either an increase in traffic levels or a change in <br />location that results in substantial safety risks? <br /> <br />d) Substantially increase hazards due to a design feature <br />(e.g., sharp curves or dangerous intersections) or <br />incompatible uses (e.g., farm equipment)? <br /> <br />e) Result in inadequate emergency access? <br /> <br />f) Result in inadequate parking capacity? <br /> <br />g) Conflict with adopted policies, plans, or programs <br />supporting alternative transportation (e.g., bus turnouts; <br />bicycle racks)? <br /> <br />DISCUSSION: <br /> <br />Potentially <br />Significant <br />Impact <br /> <br />Potentially <br />Significant unless <br />Mitigation <br />Incorporated <br /> <br />Less than <br />Significant <br />Impact <br /> <br />No <br />Impact <br /> <br />o <br /> <br />o <br /> <br />[gJ <br /> <br />[gJ <br />o <br />o <br />[gJ <br /> <br />Construction of the new Oyster Bay Slough bridge and trail connection would be expected to slightly <br />increase the pedestrian and bicycle traffic on the San Francisco Bay Trail between Oakland and San <br />Leandro. The increase is planned and would not be considered a significant impact. <br /> <br />o <br /> <br />o <br /> <br />[gJ <br /> <br />It is estimated that construction of the bridge and trail . segment could be accomplished in <br />approximately 120 days (16 weeks or four months). Key activities (which overlap) would include <br />pile driving of the CISS piles for the bridge (which would take six weeks); construction of the bridge <br />(four weeks); and construction of the steel soldier pile wall for the trail (12 weeks) (Chen, 2005). <br /> <br />Y 42041S.OO693 . doc - 4/5/07 <br /> <br />o <br /> <br />o <br /> <br />[gJ <br /> <br />o <br /> <br />o <br /> <br />o <br /> <br />o <br /> <br />o <br />o <br />o <br /> <br />o <br /> <br />[gJ <br />o <br />o <br /> <br />o <br /> <br />o <br />[gJ <br />o <br /> <br />-38- <br />
