PROPOSAL FOR SERVICES MOUNTAIN HOUSE NEIGHBORHOODS I&J <br /> INITIAL STUDY/MITIGATED NEGATIVE DECLARATION <br /> Traffic conditions will be assessed for the proposed internal project roadway network. If <br /> significant transportation impacts,safety concerns, or other transportation issues are found <br /> regarding the proposed network,recommended adjustments will be identified and evaluated. For <br /> example,with limited access to the two neighborhoods,would there be any potential impacts with <br /> regards to queuing at several of the major intersections? Will the storage length at the gated <br /> entrance be able to accommodate the projected traffic? What would be the required intersection <br /> lane configurations? Traffic mitigation for each scenario would be identified. <br /> The analysis will include a quantitative evaluation of the proposed project as compared to the <br /> previously approved Neighborhood I and J in Specific Plan 11 (trip generation,trip distribution and <br /> turning movements,traffic volumes, <br /> intersection/roadway segment level of ; <br /> service impacts,traffic signal warrants, <br /> etc.). For example,what will the impact be KELSO Ro 43 <br /> with higher density housing? <br /> t 42 <br /> Scenarios: The traffic model runs will be 24DEANZAOLVD. <br /> completed for the following conditions: <br /> 4"H�Vti Vt[) <br /> 1.

Population/Housing <br /> Given the limited change in unit counts and types of units,impacts related to population and <br /> housing are not expected to be significant. This section will largely rely on text provided in the <br /> SP 1I Initial Study, with clarification of how units have changed under the new plan for <br /> Neighborhoods I and J. <br /> H.
