A Temecula, CA 92592 Subject: Hydrology and Hydraulic Calculations Proposed CMP Under Driveway Parcel 1 of Tract 3646 Vallejo Avenue, Temecula, CA. Reference: Grading Plan prepared by Lakeshore Engineering 30 Scale Drawing (P.N. 99-099.GP) Rancho Water District Map 200 scale, 5 foot contour interval. Gentlemen; Attached is the hydrology study for the. watershed areas feeding to the location at the proposed driveway crossing and at the exit point of the subject lot (shown as location A and B on the grading plan). Our study was conducted using the Rational Method as outlined in the Hydrology Manual (County of Riverside Flood Control Manual) and the pipe sizing was performed using Civil Tool's Program, using Manning's Equation. A Q-100 yr discharge of 1.13 cfs at the pipe inlet location and a discharge of 7.67 cfs at the easterly property line of subject lot. Based on a discharge of 1.13 cfs, a 12" diameter CMP is recommended (at 1 % slope minimum) to be installed at the location shown on plan. ton rip-rap (6" dia stones or larger, placed 48" x 48" is recommended at the point of exit of subject lot see grading plan). A one square) (please If you have any questions, please call this office at your convenience. Respectfully-Sub LAKE SHORE I Att: \ _J 31740-2 Railroad Canyon Road. Canyon Lake, CA 92587 .
