CITY OF SAN LEANDRO S A N L E A N D R O G E N E R A L P L A N U P D A T E A N D E I R EXHIBIT A: SCOPE OF WORK AND COSTS Hayward Fault, it will be essential to address the potential for ground failure, ground shaking,liquefaction,and other geologic hazards. The Planning Center I DC&E also will review available environmental databases to describe known and potential subsurface contamination in the city and the immediate vicinity, including leaking underground storage tanks. Development in areas with known or potential contamination could pose a threat to human health and/or the environment if the materials are not properly identified and managed. Hazardous materials storage, handling, and transportation issues also will be addressed. The Planning Center I DC&F_will discuss the extent of and likely risks associated with hazardous building materials. We will identify any hazards to navigable airspace associated with airports. Additionally, we will describe emergency response and evacuation plans for the City and evaluate the risk of loss of life or property damage associated with wildland fires and flooding. Federal, State, and local plans,laws,and regulations will also be described. 4.9 Noise Data The Planning Center I DC&E will review the existing Noise Element of the General Plan, review aerial photography,•and collect ambient noise level measurements to document the existing noise conditions in the city. Ambient noise monitoring will include a combination of short-and long-term noise measurements to be taken at up to 16 locations in San Leandro. These locations,envisioned to consist of three long-term (24-hour) and thirteen short-term (typically, 15 minutes) monitoring sites, will be selected by the consultant in coordination with City staff to identify and quantify the major roadway noise sources, including the I-580 and 1-880 freeways, primary City arterials, and aircraft over-flights from Oakland International Airport. The focus will be on the key sites identified for housing development opportunities. A 2014 noise contour map will be prepared based upon the data collected during the noise monitoring survey and traffic data provided by Kittelson. The existing conditions summary will also discuss applicable thresholds for ground vibration. 4.10 Air Quality and Greenhouse Gases Data The Planning Center I DC&E will describe current air quality within the San Francisco Bay Area Air Basin (Air Basin) in the vicinity of San Leandro, existing levels of criteria air pollutants available from the nearest air quality monitoring station, and a summary of regulations adopted to reduce health-based impacts THE PLANNING CENTER I DC&E 19 MARCH 3,2014
