City of Pleasanton Recycled Water Project CEQA Addendum Table 1 Environmental Review of Proposed Project Changes Environmental Issue Area Where Impact(s) were Analyzed in Prior Environmental Documents. What were the Environmental Impact conclusions for the Original Proposed Project? Do Proposed Changes Involve New Significant or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Are Prior Mitigation Measures Sufficient for Addressing Any New Potential Changes or Impacts? short-term. However, since construction activities could substantia ly increase ambient noise levels at noise - sensitive locations, construction noise could result in potentially significant, albeit temporary, impacts to sensitive receptors. Compliance with the City noise ordinance and implementation of the following mitigation measures is expected to reduce impacts related to construction noise, to a less -than -significant level. IS/MND Mitigation Measures: • Mitigation Measure NOI-1: Limit Construction Hours • Mitigation Measure NOI-2: Locate Staging Areas away from Sensitive Receptors • Mitigation Measure NOI-3: Maintain Mufflers on Equipment • Mitigation Measure NOI-4: Idling Prohibition and Enforcement • Mitigation Measure NOI-5: Equipment Location and Shielding Project Change Discussion: The proposed changes to the Proposed would have the same impacts on noise and sensitive receptors as the Original Proposed Project. The addition the new booster pump station would not result in any new noise impacts as was evaluated in the IS/MND. Also, the construction activities associated with the new booster pump station would be substantially the same as they were originally described in the IS/MND. The Revised Proposed Project therefore would not have any incrementally significant effects on noise and sensitive receptors as defined in CEQA Guideline section 15162(a). Population and Housing IS/MND Page 3-34 NI No No No Yes IS/MND Discussion: The Proposed Project would not induce population growth either directly or indirectly. The Proposed Project/Action would be to serve the City with up to 2,500 afy of tertiary treated recycled water for irrigation purposes. This would help supplement the City's current groundwater supplies, but would not be a sufficient supply to induce urban growth in the area. Construction of the Proposed Project/Action would avoid the need to demolish any existing houses and would not affect any other housing structures. In addition, construction, operation, and maintenance would not result in any substantial increase in numbers of permanent workers/employees. Therefore, no impacts are anticipated and no mitigation is required. IS/MND Mitigation Measures: • None identified or necessary. Project Change Discussion: The proposed changes to the Proposed would have the same impact on population and/or housing as the Original Proposed Project. The addition of the new booster pump station would not induce growth and thus would not result in any new impacts to population growth as was evaluated in the IS/MND. Also, the construction activities associated with the new booster pump station would be substantially the same as they were originally described in the IS/MND. The Revised Proposed Project therefore would not have any incrementally significant effects on population and/or housing as defined in CEQA Guideline section 15162(a).
