(Rincon) for the Indian Grove Development Project, located in the City of Oceanside (City), California. The purpose of this report is to document the existing conditions of the survey area and to evaluate the potential for impacts to special-status biological resources for compliance with the California Environmental Quality Act (CEQA) review process. 1.1 PROJECT LOCATION AND DESCRIPTION The project site is located within the Morro Hills neighborhood of the City of Oceanside. Specifically, the site is situated just northeast of the intersection of Sleeping Indian Road and Grove View Road. The site is flanked by Grove View Road and agricultural fields to the east, private properties to the west and south of the site, and more agricultural fields and private property to the north. The survey area is depicted in Township 10 South, Range 4 West, and Section 26 of the U.S. Geological Survey (USGS) Morro Hill, California 7.5-minute topographic quadrangle (Figure 1). The project area lies within an Agricultural Exclusion Zone as reflected in the North County Multiple Habitat Conservation Program, Oceanside Subarea Plan (City of Oceanside 2010). The proposed project will include the grading and development of a three separate residential lots on approximate 8 acre property split from a larger parcel (APN 122-310-11). The homes will range from 3,630 to 4,775 square feet on approximately 2.5 acres of land each. Two of the homes will be single story and one house will be two-stories, each with three car garages and other extensive outdoor amenities. The project will also involve the establishment of a 10-foot wide rock lined channel along an existing drainage for flood control purposes. Project descriptions in this report are based on the City of Oceanside Tentative Parcel Map dated January 16, 2016. The proposed project is located within the Oceanside Subarea Habitat Conservation Plan/Natural Community Conservation Plan (hereafter, SAP and/or Plan). This Plan is a Natural Community Conservation Plan (NCCP) and a Habitat Conservation Plan (HCP) pursuant to Section 10(a) of the ESA (as amended) and is discussed in greater detail in Section 4.5. nVision Development, Inc. 1 Indian Grove Project Biological Resources Technical Report ^_ P A C I F I C O C E A N 0 2.5 5 Miles Imagery provided by ESRI and its licensors © 2016. ± ^_ Project Location Basemap Source: ESRI Data, 2004, and USGS/CDFG, 2002. ^_ Regional Location Figure 1 nVision Development, Inc.
