POTENTIALLY ISSUES POTENTIALLY SIGNIFICANT LESS THAN NO SIGNIFICANT UNLESS SIGNIFICANT IMPACT SOURCES ISSUES MITIGATION IMPACT INCORPORATED 'LANATION: On behalf of the applicant, a traffic study has been prepared by TJKM Transportation Consultants. The report is Ided as an appendix. Study intersections include: Davis Street/Callan Avenue/E. 146' Street; Davis Street/Hays Street; Davis 3treet/Carpentier Street; Davis Street, San Leandro Boulevard; Davis Street/Alvarado Street; Davis Street/Douglas Drive/Pierce kvenue; Davis Street/Wayne Avenue/Preda Street; Davis Street/Interstate 880 northbound ramps; and Davis Street/I-880 nuthbound ramps. The report concludes that under existing conditions, 8 of the 9 study intersections operate acceptably (LOS D or oetter). The intersection of Davis Street/Carpentier Street operates at LOS F. In all scenarios, the Davis Street/Carpentier Street intersection is expected to operate at LOS F. Although a signal is warranted under the "Existing plus Approved plus Project plus Cumulative scenario, if Davis Street signals between E. 14`s Street and I-880 are connected to Caltrans' CT/NET system, this will allow the intersection to operate acceptably without signalization in all scenarios. The other study intersections continue to operate at acceptable levels of service (LOS D) (except for Davis Street/Carpentier Street, as noted above) under the "Existing plus Approved plus Proposed Project" scenario. The only intersection with a change of status under this scenario is the Davis Street westbound I- 880 northbound on -ramp. The on -ramp queue is expected to reach 63 vehicles, while the on -ramp capacity is approximately 37 vehicles. This may be mitigated by adjusting the ramp metering times at the eastbound and westbound Davis Street on -ramps to northbound I-880. The project has been designed to meet the City's standard for off-street parking. The internal circulation of the site appears to be adequate, with one exception. The control of the intersection at the north end of Preda Street should be controlled by stop signs on the east -west approaches. The following mitigation measures are recommended in order to reduce potential traffic impacts to a level of insignificance: • At such time as deemed necessary by the Transportation Manager, the applicant shall be responsible for funding connection of the existing traffic signals along Davis Street, between E.14 Street and I-880 to Caltrans' CT/NET system (not to exceed $100,000). • Prior to approval of the Final Map, the site plan shall be revised to show STOP signs on the east -west approaches for the intersection at the north end of Preda Street, to the satisfaction of the Transportation Manager. The STOP signs shall be funded and installed by the applicant prior to issuance of the first Occupancy Permit, to the satisfaction of the Transportation Manager. At such time after project occupancy as deemed necessary, the City's Transportation Manager will coordinate with Caltrans for adjustment of metering on the eastbound and westbound Davis Street on -ramps to northbound I-880. 11. PLBLIC SE RVICES. Vould the project result insubstantial adverse physical impacts associated )pith the provision of new or physically altered governmental facilities, need for new or phvsically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for anv of the.. ublic services: X a. Fire rotection? X 2 b. Policeprotection? X 2 C. Schools? X 2 d. Parks? X 2 e. Other public facilities? EXPLANATION: Although currently vacated, the project site has been previously developed and can be described as an urban environment. Given the urban context, the fact the site has been served by public services in the recent past, and the scale �of proposed residential development, public service impacts related to fire and police protection and anticipated to be less than significant. Because local school districts are operating at or near capacity, the addition of 70 single-family units could impact the local schools. The applicant shall pay the state -mandated school fee of $2.05/square foot, plus the applicant has entered into an agreement with the San Leandro Unified School District to contribute an additional $250,000 to offset impacts of the project on the local schools. Therefore, with inclusion of the applicant's additional contribution on top of the state -mandated school fee, potential impacts to schools are anticipated to be less than significant. The site plan includes a public open space element consisting of a walking trail along San Leandro Creek and a central 0.31-acre passive park with a tot -lot and benches. According to the park space requirements contained in the City's Subdivision. Ordinance, a total of 0.70 acres of on -site park space would be required. The following mitigation measure is recommended in order to reduce potential impacts related to parks to a level of insignificance: - Prior to Final Map approval, the applicant shall submit park in -lieu fees, to be determined by the City Engineer, to off- set the deficiency of on -site park acreage.
