Section 8 <br />Construction of the Water SupplylBack flush Pipelines, Injection Wells and <br />Shared Structures <br />The proposed well sites, water supply pipeline alignment and shared <br />communication structures would be constructed on existing paved parking areas <br />and roads or within the footprint of existing structures. No Waters of the <br />U.S. /State or Wetland Waters of the U.S./State are located in the area where <br />these components of the Proposed Project would be constructed. <br />The Proposed Project includes the construction of back flush pipelines that would <br />discharge well water into Centennial Lake and the Greenville Banning Flood <br />Control Channel. The back flush pipeline to Centennial Lake would tie into an <br />existing wet well that is formerly used to irrigate the landscape at Centennial <br />Park. The construction of the back flush pipeline to Centennial Lake would not <br />impact waters of the U.S. or State. <br />The back flush pipeline to the Greenville Banning Flood Control Channel would <br />discharge into an existing gutter catch basin and then drain into the Greenville <br />Banning Flood Control Channel. The construction of the back flush pipeline to <br />Greenville Banning Flood Control Channel would not impact waters of the U.S. or <br />State. <br />Heritage Museum Monitoring Well <br />The area of construction impact would occur on a disturbed upland area that is <br />presently used as a parking area. There are no Waters of the U.S./State or <br />Wetland Waters of the U.S./State located in the area where the monitoring would <br />be constructed. <br />Mitigation Measures, <br />No mitigation measures required. <br />Level of Impact <br />No adverse impact <br />8.15 The Wild and Scenic Rivers Act <br />Is any portion of the project located within a wild and scenic river? <br />9 No. The project is not located near a wild and scenic river. <br />The project area is located in the Santa Ana River Watershed. Within the Santa <br />Ana River Watershed there are no Wild and Scenic Rivers, Therefore, the <br />construction and operation of the Mid Basin Centennial Park Injection Wells <br />Project would not result in adverse impacts to any wild and scenic rivers. <br />Mid Basin Centennial Park f6tn'*6Project Final EIR 8-24 <br />
