The design flows derived herein shall be used to prepare a comprehensive hydraulics study for sizing storm drain facilities and calculating cost estimates for this development project. Plans for the construction of these storm drain facilities have been prepared by NBS/Lowry, and will ultimately require approval from Riverside County Flood Control and Water Conservation District (RCFC). This report substantiates the proposed design of the storm drain facilities. 1 A.. I '. I . . '. . I . . I . I . . . . . . SITE DESCRIPTION Rancho California Development company's P.M. 23496, hereinafter referred to as the North Plaza, proposes 16 commercial land use parcels on 58.83 acres. The site is in Rancho California/Temecula, County of Riverside, between Interstate Freeway I-IS and Ynez Road extending approximately from 1400 feet to 3800 feet north of Rancho California Road. The boundary of the site is best described by Assessor's Parcel Nos. 921-080-014,017,018. Please refer to Parcel map 23496. The site is bounded to the northeast by the vacant lots 10-12 of Tract 3334, to the north by an auto dealership on Parcel 7 of P.M. 119/36-37, to the west by the northbound lanes of I-IS, to the south by the existing Rancho California Plaza and to the east by a portion of the proposed Rancho California Town Center (P.M. 22863). The site's easterly boundary is subject to these off site flows: QlOO TRIB. AREA EXIST. NO. (CFS) (ACRES) FACILITY 1 57.3 21. 6 24" CMP 2 192.4 98.2 36 CMP 3 3200* 2840 TRIPLE 7' X 10" RCB * 3200 = 1940 CFS (Empire Creek) + 1260 CFS (Mira Loma Wash) * Unbulked flows provided by RCFC Local flows 1 and 2 above sheet flow in a westerly direction toward Empire Creek and I-IS. Empire Creek currently employs concrete lining on the westerly side leaving the easterly side and bottom with an earth surface. It continues toward I-IS to the Empire Creek Bridge, which was recently lengthened to add additional driving lanes. Only the bridge portion of Empire Creek will be used here since the concrete lining is to be abandoned or removed. The construction of I-IS included a 48" RCP culvert and a 36" RCP culvert to convey local approaching surface runoff beneath the freeway. These culverts are to be utilized in this Parcel map's proposed storm drain system. 2 ~ I . I I I I I I I . I I I I I I . . I PROJECT DESCRIPTION Storm runoff generated onsite is proposed to surface drain in the parking lots to strategically located catch basins or grates at low points onsite. Flows originating offsite are anticipated to be intercepted and conveyed by surface streets. When street capacities are reached, catch basins and underground pipes are to be utilized to transport the runoff. Empire Creek Hydraulic Design Calculations and Improvement Facility Drawings are to be submitted separately from onsite facilities. This report addresses the local flows discussed in the site description, onsite storm drains and the adequacy of the culverts under I-IS for the proposed 100 year flow volumes. The existing CMP'S under Ynez Road are undersized for today's hydrologic runoff quantities and are to be abandoned or partially removed. In their place, headwalls and appropriately sized reinforced concrete pipes are proposed to carry the flows through the site to acceptable locations. Flows that are generated onsite are discharged into existing drainage patterns. These flows are conveyed by way of parking lots, swales, concrete brow ditches, grates, inlets, and pipes on and around the perimeter of the site including as a precaution, overland emergency drainage escapes. Refer to proposed grading plan for Tr. 23496. The attached hydrology map, grading plan, and storm drain plans describe the construction of the proposed storm drain facilities, and this report substantiates the design. METHOD OF ANALYSIS Peak flows are calculated using the Rational Method per Riverside County Flood Control and Water Conservation District's Hydrology Manual dated April, 1978. A 100 year frequency storm has been evaluated for this area to determine design flow values and sizes of proposed storm drain facilities to convey these flows. The hydraulic Analysis Plus Civilsoft. calculations were performed using the Storm Drain program by Los Angeles County Public Works and This site is within the boundaries of Riverside County Flood Control and Water Conservation District's Master Drainage Plan for the Murrieta Creek Area, Zone 7, dated March, 1986. Supporting hydrologic and hydraulic calculations are provided to substantiate the design of the proposed storm drain facilities. A hydrology map is included showing cumulative flows at particular points of concentration. 3 (p I . I I I I . I I . I I I I I . . . . GENERAL INFORMATION Submitted with this report is an appendix of a hydraulic study performed by Robert Bein, William Frost and Associates on Parcel 2 of Parcel Map 23496. In the design of Line "3", we used a more conservative flow to size the pipeline so that Line "3" will not affect the proposed plans for Parcel 2, of Parcel Map 23426. 4 \, . . I I I I . I I 1- . .
