Windsong Shores is comprised of approximately five' (5) acres adjacent to the north bluff of Agua Hedionda Lagoon lying between Interstate 5 and the AT&SF Railroad. The site will be developed with 130 condominium units built over an underground garage. The land presently slopes to the south and down the bluff to the lagoon; when developed, the area north of the bluff face will be drained by a system of pipes which will connect to an existing drainage system located on the property immediately to the north. Enclosed location and rough grading plans show this site and its proposed drainage system, plus the area northerly that is tributary to the same outfall drainage pipe. The intent of this report is to provide runoff and pipe flow calculations to support the proposed private storm drain facilities which include pipes, inlets and cleanouts. I I I I I I I I I I' I I I I I I II I I Windsong Shores Drainage Study Job No. 300-2 August 1989 Page 2 of 34 Drainage maps (reduced site grading plans and offsite topographic maps) are included with this study; these maps also show the existing and proposed storm drains on and adjacent to this development. I I I I I I ,I I Windsong Shores Drainage Study METHODOLOGY Job No. 300-2 August 1989 Page 3 of 34 This study utilizes the design criteria outlined in the San Diego County Flood Control District's Design and Procedure Manual in its calculations and analyses. The 100-year storm runoff discharges are analyzed throughout the storm drainage facilities.· Onsite An inlet on the main storm drain line under the garage has been selected as the representative "collection point" for each tributary area or group of areas. Actual inflows into the main line will occur at various points along its length from roo·f and deck drain laterals to be constructed with the building, as well as from the area drain laterals shown on the rough plan. The average runoff coefficient (C) for each tributary area is based on the approved site plan and final landscape plans: a. Building & on deck planter areas C = 0.85 (Areas 1, 2, 3, 5, 9 & 12) b. Landscaping and pool areas C = 0.55 (Areas 4, 6, 7 , 10 & 11) c. Landscaping & access drive (Area 8) C = 0.7 I I I I I' I: I I I I I I I I I 1 1 I I Windsong Shores Drainage Study Offsite Job No. 300-2 August 1989 Page 4 of 34 Existing inlets and junctions have been selected as "collection points" for the tributary areas. The average runoff coefficient for each tributary area was established by visiting the site and using the aerial topo map of the area (see "Offsite Tributary Area Map", Page 33). Existing drainage systems were taken from Asbuilt plans on file with the City, supplemented by field survey information in the vicinity of the downstream connection point near the western project boundary. The Appendix contains the Intensity-Duration Design Chart and calculations, including the Intensity equation, which was used directly since the chart only goes down to ten (10) minutes. It also contains the Pipe Flow Charts used to determine the average normal depth and velocity in each reach of pipe and other reference materials.
