The subject site is approximately 1.261 acres, and the general location of the site is illustrated in the “Vicinity Map” in “Appendix A” of this report. Section II Methodology For both, the pre-developed and post-developed conditions, the drainage sub-areas were studied for 10-year and 100-year storm events with 24-hour storm duration using Synthetic Unit Hydrograph Method in conformance with Riverside County Hydrology Manual. The peak flow rates for pre-developed and post-developed condition were developed using CivilDesign software Version 9.0. The required underground pipe storage system is calculated using Hydraflow Hydrograph software. Section III Project Description Pre-developed Site Conditions Currently, the pre-developed site consists of approximately a total of 1.261 acre of undeveloped land mostly barren with poor vegetation. In the pre-developed condition, the entire site is considered as a single basin. The runoff from the site sheet flows toward the east side and discharges into a local depression at the south-east corner of the site. Based on the websoil survey data, the project site is classified as Hydrologic soil type C. Refer to the “Pre-developed Hydrology Map” in “Appendix F” for an illustration of the pre- developed drainage patterns. The following table summarizes the data and results for the 10-year and 100-year storm events with 24-hour storm duration in the pre-developed condition. All calculations can be found in Appendix D of this report.

In the post-developed condition, the site is divided into two distinct sub basins. The runoff from sub basin DA1.1 will sheet HYDROLOGY STUDY Madison Avenue, Temecula CA 92590 Hydrology Report Prepared for Commercial Development flow over the parking areas and driveway aisle into the curb and gutter system and get intercepted at Flogard catch basin. The runoff will then be pumped partially into the BioPod Biofilter for treatment and the remaining runoff will be stored in the 36” CMP circular pipe storage. The excess runoff from the drainage system will be discharged on to the barren land at the north-east side of the site. The runoff from sub basin DA1.2 will sheet flow over the parking areas and driveway aisle into the curb and gutter system at the south side and will be finally discharged on to the barren land at the south-east side of the site. All calculations can be found in Appendix D & E of this report. Refer to the “Post-developed Hydrology Map” in “Appendix F” for an illustration of the post-developed drainage patterns. The following table summarizes the data and results for the 10-year and 100-year storm events with 24-hour storm duration in the post-developed condition without mitigation. Table-2: Post-developed flow rates using Synthetic Unit Hydrograph method without mitigation: Drainage Area Area (acre) Q10 (cfs) Q100 (cfs) DA1.1 0.569 0.21 0.35 DA1.2 0.692 0.26 0.42 Total 1.261 0.47 0.77 Note: The 100-yr peak flow rates are used to size the inlets. Refer to calculation in Appendix C & “Post-developed Hydrology Map – Rational Method” in Appendix F. Conclusion The difference in peak flow rate of pre-developed and post developed condition for 10 and 100-yr storm events are primarily due to increase in impervious area which is approximately 85% in the developed condition. The excess runoff will be attenuated using underground pipe storage and BioPod Biofilter. Below is the hydrology summary table of entire site for pre-developed and post-developed condition. Table-3: Pre-developed & Post-developed flow rates comparison after mitigation: Pre-developed Discharge Post-developed mitigated discharge Drainage Area Area (acres) Q10 (cfs) Q100 (cfs) Drainage Area Area (acres) Q10 (cfs) Q100 (cfs) DA1 1.261 0.38 0.73 DA1.1 0.569 0.11 0.27 DA1.2 0.692 0.26 0.42 Total 1.261 0.38 0.73 Total 1.261 0.37 0.69 We conclude that adequate storage volume has been provided in the post-developed condition. This indicates that there will be no adverse impact on the downstream end due to the development of this site. The underground pipe storage system will attenuate the post-developed flow rate and will hold the post-developed 10-year &100-year peak flow rates below the respective pre-developed flow rates.
