LAND lfSE ELEMENT . Traffic Noise . The greatest source of noise affecting the City is vehicle traffic on major arterial roadways and area freeways. Many areas of the City are subject to high ambient noise levels in excess of 70 dBA. Most areas along major arterial roadways are subject to noise levels in excess of 65 dBA. Airport Noise -The City updates its Airport Environs Element detailing potential noise impacts for the Planning Area impacted by the John Wayne Airport. Although the area within the 60 and 65 CNEL contours (Noise Impact Zone 1 and 2) is relatively small, there are sound attenuation to minimize the adverse effects on the community within the specified areas. Utilities The City of Santa Ana, because of its built-out character, has a well-developed system of public infrastructure which includes water supply and distribution, sewer facilities, and storm drains and other flood control facilities. This section provides an overview of those factors which were considered in the Element's preparation including water, sewer, and flood control infrastructure, as well as the handling and disposal of solid waste. Waler Service Purveyors -Domestic water services in Santa Ana are primarily provided by the City of Santa Ana Public Works Agency. There are two small mutual water companies which serve a minor portion of the City through groundwater wells. The Santa Ana Water Department delivers an average of 43 million gallons of water daily to some 48,000 customers. This service is provided through 17 groundwater wells, 444 miles of water mains, and 8 storage tanks or reservoirs with a combined capacity of 45 million gallons. Wells in the Santa Ana area withdraw water from between 600 to 2,700 feet below ground level. (ReVised FebnJary 2.2009) 4-48 Resolution No. 2009-011 Page 40 of 42
