The December 2000 San Joaquin County Traffic Study Guidelines were used to calculate the fair share contribution of a development to the costs of improvements necessary to fully mitigate significant project impacts. The project's fair share contribution for the improvement of Lower Sacramento Road between Eight Mile Rd and the Stockton city limits to an interim divided 4-lane facility is as follows: Project's fair share responsibility = The number of'Project generated trips' at a location The total number of trips at that location _ 618 17,610 — 3.51% The cross section for the 4-lane interim condition for Lower Sacramento Road shows a 4-lane divided roadway with a 16 ft. median, and 37 ft. of pavement in each direction. Allowing for the existing 30 ft of pavement (a 12 ft, lane plus a 3 ft. paved shoulder in each direction), it is assumed that the ultimate roadway would provide an additional 44 ft. of paved roadway width. Assuming a unit cost of$3 per sq. ft. for new pavement along the 7,170 ft. section of roadway between Eight Mile Road and the Stockton city limit (and excluding the costs associated with the median, sidewalk, gutter, underground drainage, lighting, etc.), the preliminary planning level cost estimate for this improvement would be approximately $946,500. If the project's fair share contribution were 3.51%, their total fair share contribution would be approximately$33,200. Project Access Northern and southern access driveways to the project site were analyzed for Existing plus Approved Project plus Project Conditions. Both of the access intersections would operate at LOS D or better. It is recommended that both of the driveways provide separate left and right turn lanes based on typically accepted left tum warrant criteria. Due to the high design speed of Lower Sacramento Road, care should be taken to ensure the safety of vehicles turning in and out of the driveway. A planned roadway improvement in the future will include a median in the roadway which would restrict access to right-in/right-outs. Following this improvement, traffic heading to the south would be required to tum right out of the project site to northbound Lower Sacramento Road, then negotiate a northbound-to- southbound U-turn at perhaps Eight Mile Road, which is the nearest intersection to the north. Traffic arriving from the north would be required to negotiate a southbound-to-northbound U- turn at perhaps Marlette Road, which is the nearest intersection to the south, before continuing northbound to turn right into the project site. For the near term condition, it is not believed this restriction would be warranted provided adequate sight distance is provided for the existing two-lane road. To ensure the safety of vehicles exiting from the project site onto Lower Sacramento Road, adequate comer sight distance should be provided. The sight distance methodology outlined in both Caltrans' Highway Design Manual, 4h Edition, as well as methodologies described in "A Delta Church of the Nazarene July 3, 1001 Traffic Impact Analysis 43
