Letter F <br /> STATE OF CALIFORNIA Edmund G.Brown Jr., Govomor <br /> PUBLIC UTILITIES COMMISSION <br /> _--- 535 VAN NE5S AVENUE <br /> BAN FR4NCi5CO3 GR 941023238 <br /> June 22, 2011 <br /> Kevin Swanson <br /> San Joaquin County <br /> 1810 E. Hazelton Ave. <br /> Stockton, CA 95205 <br /> Re: Notice of Completion,Draft Environmental Impact Report (DEIR) <br /> Munn& Perkins Quarry Excavation Permit <br /> SCH#2005082001 <br /> Dear Mr. Swanson: <br /> i <br /> As the state agency responsible for rail safety within California, the California Public Utilities <br /> Commission (CPUC or Commission)recommends that development projects proposed near rail <br /> corridors be planned with the safety of these corridors in mind. New developments and <br /> improvements to existing facilities may increase vehicular traffic volumes, not only on streets and <br /> at intersections, but also at at-grade highway-rail crossings. In addition,projects may increase F-1 <br /> pedestrian traffic at crossings, and elsewhere along rail corridor rights-of-way. Working with <br /> CPUC staff early in project planning will help project proponents,agency staff,and other <br /> reviewers to identify potential project impacts and appropriate mitigation measures, and thereby <br /> improve the safety of motorists,pedestrians, railroad personnel, and railroad passengers. <br /> The Transportation/Circulation section of the DEIR fails to evaluate traffic safety issues at several <br /> at-grade railroad crossings to be used by the Quarry trucks to and from the project site. Any <br /> increase in traffic to the at-grade crossings by this project need to be evaluated for potential <br /> impacts to safety and hazards. <br /> In general,the major types of impacts to consider are collisions between trains and vehicles, and <br /> between trains and pedestrians. Measures to reduce adverse impacts to rail safety need to be <br /> considered in the DEIR. General categories of such measures include: F-2 <br /> • Installation of grade separations at crossings, i.e.,physically separating roads and railroad <br /> hack by constructing overpasses or underpasses <br /> • Improvements to warning devices at existing highway-rail crossings <br /> • Installation of additional warning devices <br /> • Improvements to traffic signaling at intersections adjacent to crossings, e.g.,traffic <br /> preemption. <br /> • Installation of median separation to prevent vehicles from driving around railroad crossing <br /> gates <br />
