<br />~ <br />pLEASANTON <br /> <br />Exhibit A <br /> <br />. The analyses of direct and indirect <br />impacts to sensitive biological species; <br />and <br /> <br />. The effectiveness of the mitigation <br />measures. <br /> <br />Data from the project sponsor, as reviewed <br />by EIP, will be used to analyze and quantify <br />potential impacts of the project and related <br />construction activItIeS on biological <br />resources. It is expected that this assessment <br />by the project sponsor will address the direct <br />and indirect effects on habitat quality and <br />wildlife value for each vegetation <br />community. Additionally, discussions of <br />each of the sensitive plant and animal species <br />occurring and expected to occur onsite <br />should be included in the analysis. Impacts <br />to individual community types and <br />populations of sensitive species should be <br />quantified where possible. Potential indirect <br />impacts to be included in the technical study <br />by the project applicant should address an <br />assessment of habitat changes, drainage and <br />runoff impacts, and general human <br />disturbance impacts such as construction <br />traffic, invasive non-native plant species, and <br />increased use of the site <br /> <br />If biological impacts associated with the <br />proposed project would be significantly <br />greater than those associated with the <br />Specific Plan, EIP will recommend specific <br />mitigation measures for all significant <br />impacts. The SEIR will also present <br />potential permit requirements as appropriate. <br />Mitigation requirements will be assessed <br />based on the areas and acreages to be affected. <br />Potential mitigation sites within the project <br />area will be identified, where feasible. <br /> <br />In addition to the above assessment, which is <br />anticipated to be based on WRA's work, an <br />EIP botanist will inventory heritage trees, <br /> <br />within the project site as defined by City <br />ordinance. EIP will prepare a technical <br />memorandum summarizing the findings of <br />the tree survey, including potential impacts <br />to heritage trees. Mitigation measures to <br />protect those trees to be preserved, to <br />transplant significant trees (if possible), and <br />to replace heritage trees will be <br />recommended. <br /> <br />Hydrology/Water Quality. The hydrology <br />section of the SEIR will contain a discussion <br />of the existing hydrological setting and <br />potential impacts resulting from the project <br />that would be different from those described <br />in the Specific Plan EIR. The following <br />existing hydrologic conditions <br />(environmental setting) will be described: <br /> <br />. Maps of drainage patterns and <br />drainages. <br /> <br />. Delineation of the lOO-year floodplain <br />and Del Valle Dam flood inundation <br />area. <br /> <br />. <br /> <br />Estimates of existing natural runoff. <br /> <br />. <br /> <br />Description and capacity <br />existing drainages and <br />basins. <br /> <br />Description of planned improvements. <br /> <br />of the <br />detention <br /> <br />. <br /> <br />Existing water quality of on-site <br />waterways, if any. <br /> <br />Groundwater quality and quantity. <br /> <br />For the impact analysis, the anticipated <br />areas of discussion include: <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />The flood potential and adequacy of <br />flood control measures of the major <br />and minor drainages on, and in the <br />vicinity of, the project site. <br /> <br />EIP Associates <br /> <br />2.15 <br />
