Geotechnical findings and associated recommendations were prepared by others separately. This project proposes medium-high density residential development at south of project site and 1/3 of the project site at north will remain vacant for a future development. The primary objectives of this report are as follows: 1. Delineate the tributary drainage areas to proposed facilities. 2. Based on drainage patterns, ground slope, land use and soil type and using the Riverside County Rational Method, perform hydrologic calculations of on-site drainage facilities. 3. Based on the hydrology results and physical site requirements, design the storm drainage facilities to convey the computed design discharges. 4. Mitigate of increased runoff down to the existing flows. 5. Determine the 10-year and 100-year proposed condition flow rates in accordance with the Riverside County Flood Control & Water Conservation District Hydrology Manual (RCFC&WCD). The hydrologic analysis was performed using the Advanced Engineering Software computer program developed for RCFC & WCD Rational Method (AES, 2013). 1.2 Existing Conditions This site was previously mass graded and does not appear as shown in the existing condition exhibit or calculations. The exhibit and calculations were pulled from a previous study prepared by Richard McMahon dated October 28, 2003. To accurately show the relationship between the existing and proposed conditions, it is necessary to show the existing conditions before the site was mass graded. The site is presently vacant with little vegetation and sloping up from Rancho California Road to a ridge dividing the north side of the property from the south side. Elevations on the site vary from 1095 feet above mean sea level (MSL) to 1208 feet. Based on existing topography, rainfall runoffs generally run to the north, collects into two existing 18” CMP and 30” RCP underground storm drain systems on Rancho California Road. The 30” RCP pipe will be used after development to convey water away from the project. There is very little runoff coming from off-site which is not expected to impact the site. The subdivisions to the east, west and south carry water away from the project. The soil type in the on-site area is primary type B. The hydrology study titled “Drainage Study for Temecula Village, Development Plan No. PA00- 0140”, dated October 28, 2003 and prepared by Markham Development Management Group, Inc. (Markham) analyzes the existing condition hydrology in detail. Excerpts from that study will be included only as reference within this report. Because the Existing Hydrology study has been completed by others, no analysis of existing condition hydrology is provided in this report. Please see approved off-site storm drain plans, in the Reference Materials Section of this report, for supporting evidence. Temecula Village Multi-Family Michael Baker International 2 Final Drainage Study 1.3 Proposed Conditions This project proposes to develop the site into apartments with associated roadway and utility improvements. The following describes the three (3) major drainage tributaries of the project. The south on-site flows will be treated and the increased runoff will be mitigated by one infiltration basin at southwest corner of the project site and underground StormTech Chambers prior to release to natural conditions. All north on-site flows will be treated and the increased runoff will be mitigated by one infiltration basin and two sediment basins prior to discharge via proposed 30” RCP into the existing storm drain system under Rancho California Road. 1.4 Project Location Description The Project is in the City of Temecula, California, and situated South of Rancho California Road between Cosmic Drive and Moraga Road. (Refer to Figure 1: Regional Vicinity Map). It is bound by residential single-family homes to the east and south and Multi-family high density residential on the west and the north side of the property. The onsite area is to be allocated toward medium- high density residential use. The study is based on the proposed Final Grading Plan of the current development area and existing topography for the undeveloped areas. The existing hydrology study titled “Drainage Study for Temecula Village, Development Plan No. PA00-0140”, dated October 28, 2003 and prepared by Markham Development Management Group, Inc. (Markham) was used to compare existing and proposed site runoff. 1.5 Objectives The objectives of this study include the following: 1. Develop a hydrology map which identifies drainage boundaries and subareas. Subarea boundaries will be based on the development drainage patterns and concentration points. 2. Identify the pre-project drainage condition in order to establish a baseline target for the mitigation of flow from tributary areas.

The boundary of the watershed associated with the Project was delineated using aerial topography, survey field shots prepared by Michael Baker and compiled for the Project. In ultimate condition surface runoff contained within proposed streets where it is directed to catch basins and connected to the underground storm drain system. There are two basins located on the site. The drainage basins consist of relatively flat rough graded site with water quality features and storm drain outlet structures. Site runoff connects to an existing 30” storm drain system on Rancho California Road. 2.1.1 Drainage Area A A large majority of the site will drain to storm drain system (see hydrology map) and conveyed to the proposed Water Quality Basin A located at the NE corner of the property along Rancho California Road. The proposed on-site storm drain system does not collect any off-site flows. The outlet structure has been designed to allow for treatment of the Design Capture Volume. A weir structure is proposed to allow 100-yr event to bypass over the weir and into the proposed storm drain line and will discharge flows into existing 30” storm drain on Rancho California Road. 2.1.2 Drainage Area B & C The areas of the south site drain to storm drain system (see hydrology map) and conveyed to the proposed Water Quality Basin B located at the SW corner of the property and underground StormTech Chambers prior to release to natural conditions. The proposed on-site storm drain system of Area B collects a small area of off-site flows. 2.1.3 Drainage Area D The northerly entry road into the site off Rancho California Road (see hydrology map). Discharge into existing 30” storm drain thru Filterra Bioretention Filter System units in a proposed curb opening catch basins. 2.1.4 Additional Drainage Areas These areas of the Future Commercial site conveyed to two proposed Sediment Basins C & D located along Rancho California Road on each side of proposed entrance road. A weir structure is proposed to allow 100-yr event to bypass over the weir and into the proposed storm drain line and will discharge flows into existing 30” storm drain on Rancho California Road. Temecula Village Multi-Family Michael Baker International 7 Final Drainage Study 2.2 Offsite Watershed There is a small area offsite water flowing onto our site. Watershed A-34 collects some offsite runoff and will convey to a Water Quality Basin A. Watershed B-9 & B-14 collect some offsite runoff and will convey to a Water Quality Basin B. 2.3 Rational Method Hydrology calculations to determine the 10- and 100-year discharges were performed as per the RCFC&WCD Hydrology Manual guidelines. The RCFC&WCD guidelines suggest that watershed budgets for drainage areas encompassing less than one square mile be calculated using the rational method. The Project and its tributary drainage areas encompass approximately 22.1 acres. The Rational Method Calculations can be found in Appendix A. The Rational Method is an empirical computation procedure for developing a peak runoff rate (discharge) for small watersheds for storms of a specified recurrence interval. The Rational Method equation is based on the assumption that the peak flow rate is directly proportional to the drainage area, rainfall intensity, and a loss coefficient, which considers the effects of land use and soil type. The design discharges were computed by generating a hydrologic "link- node" model that divides the area into sub-areas, each tributary to a concentration point or hydrologic "node" point determined by the existing terrain or proposed site layout. A thorough technical description of the Rational Method is provided in the Riverside County Hydrology Manual. The following assumptions and/or guidelines were applied for use of the Rational Method: 1. The Rational Method Hydrology includes the effects of infiltration caused by soil surface characteristics. Hydrologic soils ratings are based on a scale of A through D, where A is the most pervious, providing the least runoff. 2. The infiltration rate is also affected by the type of vegetation or ground cover and percentage of impervious surfaces. 3. Standard intensity-duration curve data was taken from the Riverside County Hydrology Manual. 2.3.1 Soil Conditions Riverside County Flood Control and water Conservation District (RCFC&WCD) uses the SCS soils classification system, which categorizes soils into four hydrologic groups: A, B, C, and D. These groups range from most to least pervious, A to D, with D being the least pervious. Soil type D thus provides the highest runoff potential. For this project type “C” was conservatively used in the hydrologic models because the site was previously graded and compacted. Temecula Village Multi-Family Michael Baker International 8 Final Drainage Study 2.3.2 Rainfall Data All precipitation data was automatically derived from the AES Hydrology Program based on the Riverside County Hydrology Manual Rational Method module. 2.3.3 Runoff Index Runoff indexes were automatically calculated by the AES Hydrology Program based on the land use type input by the user. 2.3.4 Land Use The drainage basin is subject to ongoing development, primarily in association with Temecula Specific Plan. Aerial photography and provided Tract Maps were used to establish the land use assumptions for the drainage basin and prepare the design hydrology for the Project. The land use assumptions for pre- and post-project conditions are identical with the exception of the Project site. Under pre-project conditions, the Project site is comprised of roughly 22.1 acres of previously graded open space. Under post-project conditions, the majority of this space is allocated to medium high-density residential use and the northern part will remain for future development.

The on-site street longitudinal slope at the upstream approach to the catch basins is 0.85%. A capacity analysis of the parking areas and street section shows less than half-street flooded width for the 100-year event. See Appendix C.6 for calculations. 3.2 Bentley Flow Master – Hydraulic Toolbox Temecula Village Multi-Family Michael Baker International 12 Final Drainage Study 4 Recommendations The proposed storm drain system will include two (2) sump condition basins. The 10-year flows will be conveyed along the street within the street section, and the 100-year flows will be conveyed within the right-of-way. The storm drain system will be sized to convey the 100-year event into the basin. The detention basin is sized to mitigate the 100-year proposed (post-project) conditions to at/or below the existing (pre-project) conditions.
