Period of Record: 10/1/1948 to 12/31/2007 <br /> As shown in Figure 9, the Forward site is not located within the 100-year flood plain. The <br /> entire landfill site is within Flood Zone Designation C, which encompasses areas of <br /> minimal flooding during the 100-year, 24-hour storm event (Federal Insurance Rate <br /> Map, U.S. Dept. of Housing and Urban Development, May 15, 1980). Areas <br /> designated as "Zone C" are areas of minimal flooding that lie outside the 100-year flood <br /> plain. Since the landfill site is not located within the 100-year flood plain, an engineering <br /> analysis to determine hydrodynamic forces that would result from such an event is not <br /> necessary, as specified by Section 2595(d)(2) of Chapter 15, Title 23. <br /> Evaporation. The estimated annual evaporation for the site is 78.43 inches based on <br /> evaporation data recorded between 1919 and 1968 at Oakdale Woodward Dam <br /> (Station No. BOO 630500, latitude 37°51'28", longitude 120'52'42", Elevation 215 <br /> msl), located approximately 13 miles southeast of the site (California Department of <br /> Water Resources,1979). A minimum mean monthly evaporation of 1.14 inches has <br /> been calculated for December and January, and a maximum mean monthly <br /> evaporation of 14.69 inches has been calculated for July. <br /> Wind. The California Air Resources Board (1984) analyzed wind data for the Stockton <br /> Metropolitan Airport for the last 12 months. The prevailing wind for the Stockton <br /> station blows northwesterly for the majority of the year. During the winter months <br /> (November thru February) winds blew predominantly from the southeast. The mean <br /> annual wind speed is approximately 9.0 miles per hour. The wind rose shown in Figure <br /> 10 provides wind direction information; it was developed from the Stockton <br /> Metropolitan Airport data. <br /> Forward Composting Facility RCSI <br /> 7/20/09;Page 41 SWT Engineering <br />
