m Korve <br />i Engineering <br />Ms, Monica Suter <br />October 30, 2003 <br />Pagc 2 <br />beoome rarniliar with the project. KORVE will ascertain the completeness and accuracy of <br />available information based en a field review. <br />KORVE will obtain traffic signal plans. signing and striping plans and traffic signal timing <br />sheets from the City of Santa Ana for the fo lowing wo i rite rsections: <br />• McFadden Street at Lyon Street <br />• Lyon Street at Ritchey Street <br />KORVE will obtain existing AN', and PP.1 peak hour turning movement counts from the City <br />or Santa Ana for the following two Intersections: <br />• McFadden Street at Lynn Street <br />• Lyon Street at Ritchey Street <br />Additional AM and PM peak hour turning movement counts will not be conducted by <br />KORVE for this project. <br />KORVE will also Obtain ACT counts from. ttse City of Sunta Ana. ADT will be reviewr_d for <br />the following three locations <br />+ Lynn Street, north of McFadden Strut <br />McFadden Street, east of Lyon Street <br />Ritchey Street, south of McFadden Street <br />Additional 24 -hour ADT counts will not be conducted by KORVE for this project. <br />Task 3 - Grade Grossing Mobility Analysis <br />Upon completion of data collection efforiE. KORVE will conduct a grade crossing mobility <br />analysis at three study locations for the proposed expansion project. The three locations <br />are: <br />• Lyon Street Grade Crossing (DOT No. 025742T) <br />• McFadden Street Grade Crossing (DOT No. 025743A) <br />Ritchey Street Grade Crossing (DOT No. 026744G) <br />The mobility analysis will include a queuing analysis and a LOS analysis using Synchro <br />Highway Capacity Manual (HCfat) Operation Method for AM and P%1 peak hour using the <br />existing traffic conditions. Future traffic condition scenarios are not included jn the scope of <br />this study. The existing signal timing as related -.o 'he hate signals and railroad crossings <br />will also he evaluated. and based on the results, recommendations will be made to address <br />queuing issues. <br />The above lrarfic scenarics will be conducted fcr three possible 21temative operational <br />S <br />cenarios <br />
