JURISDICTIONAL DELINEATION REPORT FAIRVIEW STREET IMPROVEMENTS A <br />N OVEMBER 2018 FROM 9TH STREET TO 16TH STREET AND BRIDGE REPLACEMENT PROJECT `J" <br />SANTA ANA, CALIFORNIA <br />METHODOLOGY <br />The fieldwork for the jurisdictional delineation was conducted by field biologists Lonnie Rodriguez <br />and Bo Gould on February 20, 2018. Potential federal and State jurisdictional features located in the <br />Jurisdictional Delineation Limits were evaluated on foot and using aerial photographs. <br />Areas of potential jurisdiction were evaluated according to the most current Corps and CDFW <br />regulatory criteria and guidance. The boundaries of the potential jurisdictional areas within the <br />Jurisdictional Delineation Limits were observed in the field and mapped on an aerial photograph <br />with a scale of 1 inch = 100 ft. Measurements of federal and State jurisdictional areas mapped <br />during the course of the field investigation were determined by a combination of direct <br />measurements taken in the field and measurements taken from the aerial photograph. <br />Areas supporting plant species that were potentially indicative of wetlands would have been <br />evaluated according to routine wetland delineation procedures described in the Regional <br />Supplement, but none were present within the Jurisdictional Delineation Limits. Hydrological <br />conditions, including any surface inundation, saturated soils, scour marks, and/or other wetland <br />hydrology indicators were also noted. General site characteristics were also noted throughout all <br />potential jurisdictional areas, and photographs of potentially jurisdictional areas were taken (see <br />Figure 3). <br />\\vcorp12\projects\WKE1702\N ES- MI\November 2018 Sub mittal\Fairview Street I m proveme nts_Draft JD 110918.docx all/09/18» 10 <br />
