I 1. Scope of Report A master report entitled, "Drainage Report Quarry Creek," dated March 23, 2015, was prepared for the Quarry Creek development by Project Design Consultants, Inc. (PDC). The PDC master I report summarizes the pre- and post-construction hydrology for the entire project, including bio- retention!hydromodification and detention Basins BB-4 and BB-5. Sizing of treatment Best Management Practices (BMPs), and analyses of hydromodification impacts are in the SWMP I "Quarry Creek," prepared by Project Design Consultants, dated March 19, 2015. The PDC master report includes the design and modeling of the Basins BB-4 and BB-5. The I storage volumes of the combination basins were determined using hydromodification modeling software (SDHM,) along with the Rational Method Hydrograph procedure for larger storm events. These models are based upon the total area, impervious portion and rainfall totals. I Planning Area R-4 is split between the 2 basins (BB-4 and BB-5), along with other portions of the developed site (Recreational Area at PA-8, Marron Road, Adobe Springs Road, and adjacent cut slopes) and the offsite areas located just east of the project entry. I 2. Off-site Public Storm Dram System An analysis of the off-site public storm drain system capacity was performed in report titled I "Drainage Report Quarry Creek", prepared by PDC, dated March 23, 2015. The report documents that the off-site storm drain system, located downstream of the R-4 points of discharge, were designed for flows of equal drainage areas and equal development intensities. The off-site report found that the existing storm drain system has adequate capacity for the post- development runoff. Please refer to the PDC drainage report for all off-site storm drain analyses. 3. Quarry Creek Development The Quarry Creek development is located in the City of Carlsbad (City), but is bordered to the east by the City of Oceanside. The project is situated west of College Boulevard, east of Interstate 5 and south of Haymar Drive. The property is divided north and south by the Buena Vista Creek which runs east to west through the middle of the site. The first phase of Quarry Creek construction divided the individual planning areas into large sheet graded pads, and with the supporting public roads and utilities, along with the combination basins to provide Water Quality Treatment, Hydromodification Control and Detention for the ultimate project. Planning Area R-4 is located in the southwestern portion of the Quarry Creek, bounded by the Buena Vista Creek to the north, Adobe Springs Road to the north and Marron Road to the south. D:\7 1632 QC PA 4\Reporls\Hydro1ogy\2016 1026 R4A East Drainage.docx I I k I LI I I I 4. Existing Conditions In accordance with the Quarry Creek Mass Grading Plan, Planning Area R-4 is a large sheet graded pad, approximately 18.29 acres in size, with a ridgeline splitting drainage northeast and southwest. (See PDC Drainage Exhibit located in Map Pocket 1). The western portion of the I pad is directed toward BB-5, along with a portion of Marron Road is conveyed by the storm drain system named 'System 500' in the PDC drainage report. The eastern portion of R-4 is directed towards BB-4, along with Planning Area 8 (Recreational Area) and portions of Marron I Road, the adjacent slopes and some offsite area. The storm drain is identified as 'System 700' in the PDC drainage report. See Exhibit "C" for detailed hydrologic calculations from the PDC master report. 5. Post-Development Conditions I Planning Area R-4 will include both a single family portion (R-4B West), and a multi-family component (R-4A East), which is adjacent to the P-3 Recreational Area (approx. 1.1 acres). A total of 150 multi-family units will be constructed, comprised of various attached product types I (duplex and triplex buildings) and 56 detached single family units. R-4 is approximately 18.47 acres, with a net developable area of approximately 17.20 acres. This yields a net project density of 12.0 dwelling units per acre, which corresponds to Medium Density Residential (MDR) per I Table 3-1 "Runoff Coefficients for Urban Areas" of the San Diego County Hydrology Manual. In addition to landscape areas, the P-3 includes a small parking lot, play areas, walkways, a recreation building with pool and decking area. The site has a greater impervious portion (65%) I than the master design report (50%). However, the overall impervious area tributary to each basin will be less than the master SWMP, compared as follows; Drainage Comparison SB&O PDC Difference R-413 West (Basin BB-5) Impervious Area (ac) 4.66 5.47 -0.81 %Tmpervious 63% 71% -8% BB-5 Drainage Area (ac) 7.40 7.72 -0.32 R-4A East + P-3 (Basin 1313-4) Impervious Area (ac) 14.85 15.09 -0.24 % Impervious 60% 61% -1% BB-4 Drainage Area (ac) 24.93 24.59 +0.34 Total Impervious Area (ac) 19.51 20.56 -1.05 % Impervious 60.3% 63.6% -3% Total Drainage Area (ac) 32.33 32.31 +0.02 Since the total and impervious areas to each of the basins is consistent with the original design, I the treatment, HMP control, and storm discharge response from Basins BB-4 and BB-5 will function as designed. No further analyses are necessary for the R-4 or P-3 (Recreation) sites. D:\71632 QC PA4Reports\flydro1ogy\2OI61O26 R4A East Drainae.docx I [1 n I I I I I I 6. Hydrology 6.1 Design Criteria I Drainage system will be designed in accordance with the City of Carlsbad's "Engineering Standards", Chapter 5. The rational method as defined in the San Diego County June 2003 Hydrology Manual is used to calculate peak flow rates for the 100 year storm events. (See I Appendix for Reference Materials, Charts & Tables). I 6.2 Soils The assumption from the PDC report that all soils are Hydrologic Soils Group "D" was held in the estimates for this report. 6.3 Runoff Coefficient (C-Factors) With a proposed density of 12 DU/AC and approximately 60% imperviousness, a medium- density residential drainage coefficient of 0.63 was selected. 6.4 Rainfall I Rainfall intensities were calculated using the rainfall data from the County 6-Hour and 24-Hour Isopluvial Maps as follows (these are the same values used in the PDC report): Storm 6-Hour 24-Hour Ratio Adjusted Event Rainfall Rainfall P6/P24 P6 (in) (in) (in) 100-Year 2.90 5.10 57% 2.90 See Appendix for Isopluvial Maps and Figure 3-1 to determine the adjusted 6-hour rainfall. I 6.5 Results I Exhibit "A" contains 100-year rational method peak flow calculations (CivilD) for the R-4 development areas. Runoff is generally divided between the R-4A East and R-4B West. The R- 4A West portion discharges to the backbone storm drain in Adobe Falls Road at 2 locations, and I is tributary to Basin BB-4. The R-4B West portion discharges to the storm drain inlet at the north end of Marron Road, and is tributary to Basin BB-5.

Runoff comparisons should be made using the main line system time of concentration at this location, which is 11.22 minutes / I = 4.536 in/hr). Based upon the following comparison, the increase impervious area for P-3 / Recreational Lot will have negligible impact on the storm drain system.

The reductions are primarily attributable to the lower runoff coefficient and longer times of concentration. I 7. Inlet Calculations The R-4 storm drain system will include Regional Standard Drawing Type 'B" curb inlets, I located in both sag and passing grade conditions. The inlets capacities / interception flows were verified using the time of concentration for the surface tributary areas. Inlet calculations are provided in Exhibit "B". 8. Conclusion I The R-4 storm drain systems and inlets demonstrate adequate capacity. The proposed storm drain system will be consistent with the tributary areas of the original design report (PDC). No further calculations or analyses are required for treatment, HMP controls or detention.

Plot 6 hr precipitation on the right side of the chart. Draw aiine.througti the point parallel to the plotted lines. This line is the intensity-duration curve for the location being analyzed.
