AECOM was retained to conduct a <br />pavement engineering study to determine the loading impacts and cost share responsibility <br />of commercial buses, waste collection trucks, and other heavy vehicles on city street <br />pavements. The study includes all public streets maintained by Santa Ana. <br />Project Objective <br />The overall project objective was to determine the cost responsibility for commercial buses, <br />waste collection trucks, and other heavy vehicles for each city street, to provide the city the <br />basis for collecting funds from the bus and truck companies. <br />PROJECT APPROACH <br />General Methodology <br />Pavement Loadings <br />The project approach for determining pavement loadings was based on a network level <br />evaluation. This approach consisted of grouping the city streets into representative street <br />classes and determining the percent loading impact and cost responsibility of the buses and <br />heavy trucks for each street class. The bus and truck loading impacts were calculated <br />based on actual vehicle weights for each class of pavement. The bus and truck weights <br />were converted to a standard loading impact using the long -time established procedure of <br />Equivalent Single Axle Loadings (ESALs). <br />EXHIBIT 1 <br />L• <br />
