1. All future projects that require grading and excavation for the construction of building <br />foundations, parking structures, storm drains, sewer lines, etc. will be required by the City of <br />Santa Ana to have a preliminary geotechnical investigation prepared prior to the approval of <br />grading plans. The geotechnical reports will identify the potential geotechnical constraints <br />associated with the construction of each specific project. Should a geotecimical report identify an <br />existing situation that could have a potential earth resources impact to either the building, tenants <br />or adjacent properties, appropriate measures approved by the City will be incorporated into the <br />project to mitigate the potential impact. <br /> <br />2. All future Agency sponsored development located within areas subject to differential <br />subsidence and/or high/moderate liquefaction potential shall be investigated for potential impacts <br />by a qualified geotechnical engineer prior to project approval. Should the potential for subsidence <br />and/or liquefaction potential be identified, measures acceptable to the City Engineer shall be <br />incorporated into the project to reduce or eliminate the potential project impact. <br /> <br />Hydrology/Drainage <br /> <br />Development of land acquired with eminent domain could generate additional storm water runoff <br />which could impact local drainage facilities. <br /> <br />Finding 1: <br /> <br />Changes or alterations have been required in, ~?r incorporated into, the project <br />which mitigate or avoid the significant effects on the environment. <br /> <br />Facts in Support of the Finding <br /> <br />The potential significant effect has been substantially lessened to the extent feasible by virtue of <br />the following mitigation measures identified in the Final EIR and incorporated into the project. <br /> <br />1. During the review of future projects within this location, if it is determined by City staff <br />that runoff from a project could impact storm drain facilities, appropriate measures such as <br />improvements and/or upsizing will be required to reduce or eliminate the potential impacts on <br />storm drain facilities. <br /> <br />2. All future projects will be reviewed by Public Works for compliance with NPDES <br />requirements and require all applicable pollution control measures be incorporated into a project <br />to reduce or eliminate urban pollutants from entering local surface waters. <br /> <br />4 <br /> <br /> <br />
