facilities should be provided with a 30-foot minimum throat-width to accommodate up to two lanes, one inbound receiving and one outbound lane. All driveway intersections are projected to operate at acceptable conditions as "full-access" intersections. • Per the Tentative Map submitted by the project applicant, approximately thirty lots are proposed on the subdivision's frontage along Jack Tone Road. Owing to high speeds and expected significant future traffic growth on Jack Tome Road, the proposed plan will result in potentially unsafe traffic operating conditions on the Jack Tone Road segment along the project frontage. Per the San Joaquin County General Plan, direct access from single-family residential properties to a minor arterial is prohibited. Therefore, the proposed subdivision should be re-designed to eliminate individual property access directly to Jack Tone Road. The acceptability of the currently proposed subdivision design will be per the discretion of the County Board of Supervisors. The following steps are recommended to address potential safety issues with the proposed subdivision design. + The applicant has indicated that the homes on the lots fronting Jack Tone Road would have a garage and driveway design that would allow drivers from these homes to "drive(forward)into" Jack Tone Road rather than"back(reverse)into"Jack Tone Road. This would serve as a "partial mitigation" for unsafe mid-block traffic operations. It is recommended that the County place the appropriate garage and driveway design requirement as a pre-condition for approval of the proposed project. • It is recommended that under "Existing plus Approved Projects plus Project" conditions, the segment of Jack Tone Road along the subdivision frontage be widened to accommodate a curb-to- curb width of at least 60 feet, within the ultimately planned 84-foot right-of-way. Within the 60- foot curb-to-curb cross-section, one southbound through lane, one northbound through Iane and a "two-way left-turn" median lane should be provided. The two-way left-turn lane will help promote the safety of vehicles entering and leaving the mid-block driveways. Furthermore,for the segment of Jack Tone Road along the subdivision frontage, additional shoulder width of at least 12 feet should be provided outside of the northbound through lane in order that vehicles can safely accelerate(or decelerate)from(or to)the homes fronting Jack Tone Road. It should be noted that traffic volumes(on both daily and peak hour basis)on Jack Tone Road segment through the study area would ultimately (by year 2020) be close to triggering the need for widening to a four lane arterial section. If a two-way center turn lane and wide shoulders were also to be accommodated in order to enhance safety along the project frontage, then the required cross-section could potentially entail widening beyond the planned ultimate 84-foot right-of-way by year 2020, which may not be feasible. For this reason, it is recommended that the subdivision be redesigned to eliminate direct residential property access to Jack Tone Road. + Based upon an inspection of the proposed tentative subdivision map, the on-site circulation and driveway spacing are projected to be of acceptable standards. w • The project is expected to generate minimal to negligible levels of bicycle and pedestrian trips that would significantly impact off-site facilities. The recommended improvements along Jack Tone Road segment fronting the project site are projected to provide sufficient safety for potential bicycle and pedestrian activity. • This traffic study did not find a need for installation of a roundabout at any of the study intersections as a potential mitigation measure.
