Conceptual Design Documentation
Appendix A: Conceptual Design Documentation APPENDIX A Conceptual Design Documentation June 2019 A-1 APPENDIX A: CONCEPTUAL DESIGN DOCUMENTATION The environmental analyses in the NEPA and CEQA documents for the proposed improvements at Oceano County Airport (the Airport) are based on conceptual designs prepared to provide a realistic basis for assessing their environmental consequences. 1. Widen runway from 50 to 60 feet 2. Widen Taxiways A, A-1, A-2, A-3, and A-4 from 20 to 25 feet 3. Relocate segmented circle and wind cone 4. Installation of taxiway edge lighting 5. Installation of hold position signage 6. Installation of a new electrical vault and connections 7. Installation of a pollution control facility (wash rack) CIVIL ENGINEERING CALCULATIONS The purpose of this conceptual design effort is to identify the amount of impervious surface, grading (cut and fill) and drainage implications of the projects identified above. The conceptual design calculations detailed in the following figures indicate that Projects 1 and 2, widening the runways and taxiways would increase the total amount of impervious surface on the Airport by 32,016 square feet, or 0.73 acres; a 6.6 percent increase in the Airport’s impervious surface area. Drainage patterns would remain the same as both the runway and taxiways would continue to sheet flow from their centerlines to the edge of pavement and then into open, grassed areas. The existing drainage system is able to accommodate the modest increase in stormwater runoff that would occur, particularly as soil conditions on the Airport are conducive to infiltration. Figure A-1 shows the locations of the seven projects incorporated in the Proposed Action. -

Steven D. Gisler for the Degree of Master of Science in Botany and Plant
AN ABSTRACT OF THE THESIS OF Steven D. Gisler for the degree of Master of Science in Botany and Plant Pathology presented on May 23, 2003. Title: Reproductive Isolation and Interspecific Hybridization in the Threatened Species,Sidalcea nelsoniana. Abstract appro In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also been interpreted as a theoretically beneficial process for rare species suffering from low adaptive genetic diversity and accumulated genetic load. As such, interspecific hybridization, and the underlying pre- and post-mating reproductive barriers that influence its progression, should be considered fundamental components of conservation planning for many rare species, particularly those predisposed to hybridization by various ecological, genetic, and anthropogenic risk factors. In this study I evaluate the nature and efficacy of pre- and post-mating hybridization barriers in the threatened species, Sidalcea nelsoniana,which is sympatric (or nearly so) with three other congeners in the scarce native grasslands of the Willamette Valley in western Oregon. These four perennial species share a high risk of hybridization due to their mutual proximity, common occupation of disturbed habitats, susceptibility to anthropogenic dispersal, predominantly outcrossing mating systems, their capability of long- lived persistence and vegetative expansion, and demonstrated hybridization tendencies among other members of the family and genus. Results show S. nelsonianais reproductively isolated from all three of its congeners by a complex interplay of pre- and post-mating barriers. -
3.0 Environmental Setting and Biological Resources
3.0 ENVIRONMENTAL SETTING AND BIOLOGICAL RESOURCES 3.1 Introduction This section presents the environmental setting of the MSHCP Permit Area. It describes the baseline biological conditions that occur on the Solar Sites upon which the impact analysis and conservation program were formulated. This section also includes the environmental setting and biological conditions present on the Conservation Sites. A complete report documenting the surveys conducted on the Conservation Sites, the results of those surveys, and the justifications for adopting the Conservation Sites as appropriate mitigation for the loss of habitat associated with development of the project are presented in Appendix G. The setting is described in the context of the following subject areas: . Geography; . Topography; . Climate; . Land use; . Soils; . Hydrology; . Jurisdictional wetlands and waters; . Site characteristics; and . Covered Species. 3.2 Regional Setting 3.2.1 GEOGRAPHY The biological resources discussed in this section are those found within the Permit Area and on adjacent lands. The Permit Area is primarily located approximately five miles east of Taft, along South Lake Road and along Old River Road in Kern County, California (see Figure 1-2). Three of the Conservation Sites are contiguous with the Solar Sites, and three are located some distance away: one site is located one mile south of Hwy 166 and approximately 8 miles east of Maricopa (Site 17-C); and two are located approximately one mile southwest of the Solar Sites, bordering the north and south sides of the California Aqueduct (Sites 9-C and 10-C). All of the Conservation Sites are within 6 miles of the Solar Sites, except for Site S-15, which is located approximately 7 miles east of the other Solar Sites and approximately 11 miles northeast of the southernmost Conservation Site (Site 17-C) (Figure 3-1). -

Summary The Santa Ysabel Ranch Open Space Preserve was established in 2001 from a purchase by The Nature Conservancy from the Edwards Family; the Ranch is now owned by the County of San Diego and managed as a Department of Parks and Recreation Open Space Preserve. It totals nearly 5,400 acres and is comprised of two parcels; an "East Ranch” and a "West Ranch". The East Ranch is east of the town of Santa Ysabel (and Highway 79 running north) and is bordered on the east by Farmer's Road in Julian. -
