MOUNTAIN HOUSE NEIGHBORHOOD' 'PROJECT INITIAL STUDY <br /> development is consistent with assumptions in the San Joaquin General Plan 2010. Population, <br /> employment and vehicle miles traveled projections contained in this General Plan were used to formulate <br /> the applicable Clean Air Plans. The planned Mountain House Development is included in the Regional <br /> Transportation Plan. This project is a component of the Mountain House project that was approved in <br /> 1994. As a result, the project is consistent with assumptions used to formulate the applicable Clean Air <br /> Plans. <br /> The SJVUAPCD has developed measures to reduce motor vehicle-related emissions of ozone precursors <br /> and PM-10, which are referred to as transportation control measures. The project includes a <br /> comprehensive TDM and Transit Plan that is consistent with the TCMs adopted by the SJVUAPCD. <br /> Thus, this project would not conflict with the applicable clean air plans. <br /> As discussed above, the applicant has developed a Transportation Demand Management (TDM) Program <br /> and Transit Plan (The Hoyt Company, 1997)with the intent of reducing trips generated by the project. In <br /> doing so, air quality impacts are expected to be reduced. This Plan is intended to comply with the <br /> Congestion Management Program(CMP)of San Joaquin County and the San Joaquin Valley Unified Air <br /> Pollution Control District. <br /> Some of the triggers for the TDM Plan include the following: <br /> 1. Establishment of transit service once the first 25 units are occupied(taxi or dial-a-ride service). <br /> 2. Review of need for fixed-route transit service prior to building of 1,00151 home. <br /> 3. Establishment of a community telecenter when 2,500 homes are occupied. For this project, a total <br /> of 1,458 homes(plus 64 second units)are proposed. <br /> 4. Application to Caltrans or other applicable entity for start-up funds for a Mountain House <br /> Transportation Management Association(TMA) and transit/vanpool funding when 500 employees <br /> are working at Mountain House. This project could provide about 3,032 jobs in the proposed <br /> commercial and industrial development areas. <br /> 5. Annual TDM monitoring to evaluate the success of TDM programs, beginning with the first 1,000 <br /> residents and 500 employees. <br /> The mitigation measures adopted for the 1994 EIR would be adequate to mitigate any potential impacts <br /> related to compliance with the applicable plans of the SJVUAPCD. <br /> h) Violate any,air quality standard or contribute substantially to an existing or projected air quality violation? <br /> Carbon monoxide (CO) is the pollutant of greatest concern at the local level. As part of the 1994 EIR, <br /> concentrations of CO were modeled at the intersections with a combination of the highest traffic volumes <br /> congestion. Worst-case predicted CO levels identified in the 1994 EIR were below the applicable state <br /> and federal air quality standards; therefore, the impact was identified as less-than-significant. The <br /> proposed project would not result in greater CO concentrations than predicted in the 1994 EIR. The <br /> impact from this project is less-than-significant. However, to reduce overall emissions, the following <br /> Conditions of Approval are recommended: <br /> C:UOB&SxvNrnAL MMY\MALINmAL9RMY-PART7.D0C(7/2DO) 77 VG. AIR QUALITY <br />
