<br /> e) Community Participation. If warranted by the traffic monitoring program, or, if initiated
<br /> by others, the community shall participate in the traffic studies and improvement
<br /> measures for improvements not listed in Table 9.2, including the following: Eleventh
<br /> Street, Byron Road (south of Grant Line Road), existing Grant Line Road (east of
<br /> Byron Road), new Grant Line Road (realigned section east of Byron Road), grade
<br /> separation at Grant Line Road crossing the Southern Pacific railroad tracks (City of
<br /> Tracy), Middle Road extension (from Gold Rush City to Mountain House), (Cities of
<br /> Lathrop and Tracy), Altamont Pass Road (Alameda County), Byron Highway (Contra
<br /> Costa County).
<br /> fl Operation and Safety Improvements. The community shall, to the extent of its fair
<br /> share, participate in upgrading pavement sections and/or safety improvements (e.g.,
<br /> standard pavement widths and paved shoulders) when it is determined by the County
<br /> to be the primary new traffic contributor, on rural roads, including Bethany, Kelso,
<br /> Hansen, Von Sosten, Reeve, and Middle Roads, and Tracy Boulevard where
<br /> necessary to alleviate additional traffic caused by the project within the County.
<br /> g) Construction Truck Management Plan. The Construction Truck Management Plan
<br /> shall be administered by the MHCSD. It shall include identification of the preferred
<br /> routes for trucks bringing construction materials to the site, and shall also include
<br /> measures to ensure compliance by General Contractors.
<br /> h) Grant Line Road. When traffic reaches 5000 ADT, Grant Line Road (from Byron Road
<br /> to 1-580) shall be studied to determine whether it meets current road standards or has
<br /> deficiencies not identified under previous model assumptions. The study shall be
<br /> prepared by the MHCSD and approved by the County.
<br /> i) Noise Study. Prior to the widening of Grant Line Road in the vicinity of Grant Line
<br /> Village, the CSD shall prepare a noise study to determine future noise impacts and to
<br /> identify measures which can mitigate, if feasible, exterior residential noise levels to 65
<br /> dB Ldn. Any approved mitigation measures shall be implemented at the same time
<br /> the road widening is constructed.
