The project site is approximately 43 acres. 1.2 Purpose of Study The purpose of this study is to determine the anticipated runoffs during a 25-year event storm for the subject site, and to size the storm drain system adequate to catry the anticipated 25-yeaz runoff. ~' 1.3 Watershed Description Existing Draina¢e Svstem ~ The site is currently rough graded. The existing site currently sheet flows in the northwesterly direction to the off-site. There is an existing channel along Pala Road ~~ which is heavily vegetated. Prooosed Drainaee Svstem ~ The proposed site will drain via sheet flow, curb & gutter and v-gutter to the proposed catch basins located throughout the site. The proposed catch basins aze connected via an ' underground storm drain system. The proposed storm drain system will be connected to the proposed 48-inch storm drain line (by others) located near the intersection of Pala Road and Loop Road South. A small portion of the site near the intersection of Loop ' Road South and `D-D' Street will drain to the street via a parkway culvert. (See enclosed Hydrology Map). 1.4 Study Methodology ' This study was prepazed for a 25-year storm event. The Rational Method was used for the analysis. The computations were done using the Rational Method Hvdroloev ~ Computer Pro¢ram PackaQe by Advanced Engineering Software (aes), Rational Tabling Version 5.9D, release date O1/Ol/03. 1.5 References ~ 1. The proposed Grading Plans for the subject site as prepared by MCE Consultants. 2. Hydrology map included herein. ' 3. Riverside County Flood Control and Water Conservation District Hydrology Manual, dated April 1978. 1.6 Summary A runoff of approximately 41.2 cfs is expected under the proposed condition. The runoff will be collected by the catch basins located throughout the site, and dischazged via the ~ \Vv1ce-file-serverUnce filesUob\48.37 Temecula Sports Park- Wolf Creek\hydrology\hydrology report.doc page 1 ~ ~ ~ ~ L» ~~ - ~ _l~ proposed underground storm drain system. The proposed storm drains are adequately sized to handle the anticipated runoff (see Storm Drain Sizing Calculation). The ~ proposed storm drain system will be connected to the proposed 48-inch storm drain line at the westerly corner of the site. The runoff will be dischazged into the existing channel along Pala Road, which will be improved by others. Since there are no habitable ~ structures on the site, no negative impact is anticipated as a result of this project.
