A5.20 iv AIR QUALITY RESOURCES APPENDIX 1 Introduction The primary factorsRESIOURCES affecting air quality in San Luis Obispo County are: (1) the prevailing climatic conditions; (2) the type, quantity, and location of pollutant emissions; and, (3) the pollution control techniquesAPPENDIX employed by regulatory agencies and project applicants to avoid or reduce pollutant emissions. This appendix to the San Luis Obispo Conservation and Open Space Element provides background information to support the policies and implementation strategies included in the Air Quality chapter. Local Setting1 San Luis Obispo County covers an area of about 3,300 square miles along the coast of central California. For geography, climate and meteorology the county can be divided into three general regions: 1) coastal plateau, 2) upper Salinas River valley, and 3) east county plain. The coastal plateau is immediately inland from the Pacific Ocean and is typically five to ten miles wide. It ranges in elevation from sea level to about 500 feet above sea level, and is bounded on the northeast by the Santa Lucia Mountain Range. The Santa Lucia Range rises to roughly 3,000 feet elevation and runs parallel to the coast almost the entire length of the county. The upper Salinas River valley lies inland from the Santa Lucia Range in the northern portion of the county. The east county plain lies further inland along the eastern flank of the county, and includes about one third of the county‟s area. About 75 percent of the County‟s population and a corresponding portion of the commercial and industrial facilities are located within the Coastal Plateau. Because of higher population density and closer spacing of urban areas, emissions of air pollutants per unit area are generally higher in this region than in other regions of the county. The Upper Salinas River Valley, located in the northern one-third of the county, houses roughly 25 percent of the county‟s population. Historically, this region has experienced the highest ozone and particulate levels in the county. Transport of ozone precursors from the Coastal Plateau and from the San Joaquin Valley may contribute to this condition. The East County
