Dwg. D -1 Hydrology Map Map Pocket ' INTRODUCTION ' The Olive Garden Restaurant is located in the City of Encinitas approximately 5 miles east of Interstate 5, north of Encinitas Boulevard, along El Camino Real. The site is situated on the southeasterly corner of Encinitas Boulevard and El Camino ' Real. The project site as it exists today consists of two level, terraced lots, with an approximate 14' feet elevation difference between the lots. The proposed development shows the two lots level, which is accomplished by excavating 10 feet ' deep on the easterly lot and filling 5 feet of earth on the westerly lot. The site for this restaurant, owned by General Mills Restaurant, Inc., has been ' assigned a Major Use Permit (M.U.P.) number 92 -130. The existing streets fronting the north and east property lines are constructed to the ultimate right -of -way width. This study analyses drainage affecting development of the above mentioned lots, lots 18 and 19 of Parcel Map 11909. Lot 18 and Lot 19 comprise about 1.0 acre each. The total drainage area studied is approximately 2.0 acres. Stormwater runoff is conveyed as surface flow and through storm drain ' improvements. Stormwater runoff from the northern half of this development is conveyed as surface flow from east to west across asphalt paving to concrete curb and gutter. This runoff is collected into a proposed onsite stormdrain system which ' eventually makes its way to an existing offsite 48" stormdrain in Garden View Road. Stormwater runoff from the southern half of this development is conveyed as surface flow from east to west across asphalt paving to concrete curb and gutter. This runoff is collected into a proposed onsite stormdrain system located in the southwesterly corner of the site and eventually makes its way to an existing offsite 48" stormdrain that crosses El Camino Real. I ' DRAINAGE CRITERIA AND METHODOLOGY ' Design Runoff Method: Rational Method based on the County of San Diego Design and Procedure Manual. for watersheds less ' than 0.5 square miles. Storm Frequency: 50 - year storm. 100 - year storm. ' Land Use: Commercial Soil Type: Soil type is based on SCS Soil Survey for San Diego Coun ty, Hydrologic soil group "D" was used for this analysis. ' Runoff Coeffcients: "C" values are based on the County of San Diego Design and Procedure Manual. Appendix IX.
