Jack Tone Road/Kettleman Lane intersection --The installation of a traffic signal at this intersection and separate left-turn channelization for all approaches as recommended under year 2020 base conditions is projected to provide sufficient capacity to accommodate "year 2020 base plus project" traffic volumes. With the installation of a traffic signal at this intersection, the "year 2020 base plus project" AM and PM peak hour LOS "C" operating conditions are projected. Based upon the project's contribution to PM peak hour traffic growth (of 77 vehicles) over "year 2020 base" traffic volumes (of 2,442'vehicles) at this intersection, the project's fair-share of cost of improvements at this intersection is estimated to be 771(2442+77) = 3.1%. At an estimated cost of$150,000 for the installation of a traffic signal and $200,000 for widening improvements at this intersection, the project's cost fair-share is estimated to be. $10,850. Protect Driveway intersections Assuming that the mitigation measures recommended under"Existing plus Approved Projects plus Project" conditions are in place,no additional mitigation measures are found necessary under"Year 2020 Base plus ` Project:' conditions. No other intersection mitigation measures are found necessary under "Year 2020 Base plus Project" aq conditions. The recommended year 2020 lane geometrics and control at all study intersections are illustrated on Figure 11. Roadway Segments The Jack Tone Road segments within the study area are projected to operate at an year 2020 base plus ..~ project average daily traffic based LOS "E" conditions with the existing two-lane arterial/rural highway cross-section. The year 2020 base plus project AM and PM peak hour flow on Jack Tone Road segment between S.R.88/S.R.12 and Brandt Road is projected to be approximately 1,600 vehicles, which corresponds to a peak-hour based year 2020 LOS "D" roadway operating conditions on this segment of Jack Tone Road with the currently existing two-lane arterial section. The year 2020 base plus project AM r and PM peak hour flow on Tack Tone Road segment between Brandt Road and Kettleman Lane is projected to be approximately 1,400 vehicles,which corresponds to a peak-hour based year 2020 LOS"E" roadway operating conditions for this segment of Jack Tone Road with the currently existing two-lane rural highway section. + Per the County General Plan Circulation Element, Jack Tone Road segment through the study area is designated as a"Minor Arterial"within an 84-foot ultimate right-of-way cross-section. Itis recommended Am that the Jack Tone Road segment between S.R.88/S.R.12 and Brandt Road be provided,with a full-length two-way left turn lane and one northbound and one southbound travel lane with wide shoulders. Restricting mid-block access from the homes fronting-Jack Tone Road would be needed so that the segment of Jack Tone Road between S.R.88/S.R.12 and Brandt Road night be operate as a high-speed, high- capacity three-lane arterial with high access.control. With the recommended cross-section, the Jack Tone Road segment between S.R.88/S.R.12 and Brandt Road is projected to be able to sustain peak hour operating conditions of LOS "C"through year 2020 base plus project conditions. For the segment of Jack Tone Road between Brandt Road and Kettleman Lane,the two-lane arterial section(with moderate access control) as recommended under year 2020 base conditions is projected to have sufficient capacity to accommodate hourly traffic demands through year 2020 base plus project conditions., { Lockeford Oaks Subdivision Trak Impact Study Page 31 San Joaquin County R4071'S002.DOC125-6450-14
