U between the landfill and the City of Stockton,to the northwest,via Mariposa Road. The Austin Road Landfill is presently open to licensed commercial and residential franchise haulers from 6:00 a.m. to 3:00 p.m., Monday to Friday, except on holidays,when the landfill closes at 1:00 p.m., and on Christman and New Years days, when it is closed. The landfill is closed on weekends, except on five consecutive Saturdays during the months of April and May,when the landfill is open from 7:00 a.m. to 5:00 p.m. for the Stockton Cleanup. There are five full-time employees on the site, and two part-time employees work when needed (typically during peak activity periods). The number of existing non-peak activity non- truck trips traveling to and from the project site is about 16 daily trips and about 2 a.m. peak hour trips. Hence, the total number of vehicle trips currently generated by the existing landfill facility is about 216 daily trips and about 30 a.m. peak hour trips. Traffic accident data was reviewed for the primary roadways providing access to the project over the three- year period of 1996 to 1998. The statewide average for reported traffic accidents on suburdan two- and three-lane conventional roadways is 2.51 accidents per million vehicle miles traveled (MVMT). All four roadway segments—Austin Road (1.44 accidents per MVMT), Mariposa Road (0.1 accidents per MVMT), French Camp Road (0.62 accidents per MVMT), and Arch Road (0.70 accidents per MVMT) — are well below the statewide average for reported accidents. Analysis of the accident data did not reveal any unusual safety or accident problems. Level of Service is the relationship between intersection capacity and the vehicular traffic using the intersection. Level of Service for intersections is as defined in the Transportation Research Board's 1994 "Highway Capacity Manual." The designations for traffic Level of Service (LOS) are the letters"A" through "F." The letter"A"corresponds to freeflow traffic conditions,while the letter"F" represents significant traffic delays and backups. The traffic analysis considered existing, existing plus background, existing plus background plus projects, and cumulative traffic conditions. Background conditions is defined as the sum of existing plus anticipated {but not yet built}approved project trips in the vicinity. The Austin Road Landfill project adds approximately 252 (236 trucks and 16 autos) new daily trips and 38 (34 trucks and 4 autos) peak hour trips. Actual truck trips were converted to passenger car equivalents by multiplying by 2.5. All studied intersections operate at an LOS "C" or better for all conditions except the Austin Road/Mariposa Road intersection,which operates at an LOS "F" for background, project, and cumulative traffic conditions. The minimum acceptable LOS in areas of San Joaquin County outside of a city's sphere of influence is LOS "C." Because the study intersections are within the City of Stockton's sphere of influence, however, the City's LOS "D" was used to identify significant adverse impacts, consistent with San Joaquin County General Plan policies. In order to mitigate the substandard operating conditions under project and cumulative conditions, the intersection of Austin Road and Mariposa Road will require traffic signals. The landfill shall pay a fair share contribution to the County for the installation of the signals when warranted. The project's fair share contribution is estimated to be 5 percent. Biological(Vegetation and Wildlife = A recent reconnaissance of the project site, conducted on September 23, 1999, confirmed that overall conditions for biological resources remains much as it was described in the earlier document. Land use patterns within the immediate project site have not changed since the 1994 E1R. The existing landfill site is surrounded by primarily agriculturai.lands. Within the past two years,the North Branch of the South Fork of Little Johns Creek on the site has undergone maintenance for flood control, consisting of clearing of trees and shrubs from the banks and dense vegetation from the channel San Joaquin County GP-99-7, ZR-99-6, UP-99-17, ER-99-21City of Stockton Page 9 Community Development
