C. Existing Traffic Conditions <br /> In order to evaluate intersection operation, A.M. and P.M. turn <br /> movement counts and field surveys were conducted at the following <br /> intersections: <br /> Tracy Boulevard and Larch Road <br /> Holly Drive and Larch Road <br /> The turn movements were counted on Tuesday, March 28, 1989 by DRS <br /> Associates and are in Appendix A. The field survey did not <br /> reveal any critical traffic conditions . <br /> III . TRAFFICANALYSIS <br /> a. PROJECT Trip Generation <br /> The proposed use for the Project is for waste disposal and <br /> transfer. Since this type of land use is relatively uncommon, <br /> there are no standard trip generation rates available. <br /> Therefore, trip generation rates were estimated from information <br /> acquired from the City of Tracy Public Works Department. This <br /> information included the Monthly Landfill Report and the Daily <br /> Landfill Logs which specifically detail volumes of, and type of <br /> vehicles, entering the Corral Hollow Landfill. Because the <br /> subject PROJECT is being proposed as a permanent replacement <br /> refuse facility for the Corral Hollow Landfill, these existing <br /> traffic generation rates are the best data available for PROJECT <br /> trip generation. <br /> The August, 1988 to October, 1989 Monthly Landfill Report and <br /> Daily Landfill Logs were scrutinized and yielded the peak hour <br /> PROJECT traffic volumes shown in Table A. To be noted is that <br /> the design weekday A.M peak hour was chosen because the PROJECT <br /> will close at 4 : 00 P.M. Also, due to the lack of definitive data <br /> regarding changes in the publics usage of the relocated facility, <br /> the lack of resulting trip generation patterns and hourly <br /> variations in traffic volume, a conservative estimate of the <br /> current Landfill trip generation rate was needed. Therefore, the <br /> month of the maximum trip end activity at the Landfill <br /> (September, 1988) was used to determine the design traffic <br /> volumes for this study. Also to be noted is that no peak hour <br /> factor was assumed or applied to the traffic volumes, rather the <br /> average hourly volumes are used for design values due to the <br /> nature of the facility. The hourly PROJECT trips were then added <br /> to the existing A.M. peak hour traffic trips and then the total <br /> was assigned to the study intersections. <br /> 3 <br />
