The land is fairly covered with open brush and sparse development. The watershed runoff drains from the east to the west. Runoff travels along Pala Road to Temecula Creek. Approximately 240 acres of the watershed is in the Pechanga Indian � Reservation, which is sparsely developed. Three holes from the Redhawk Golf Course are currently within the project boundaries of the watershed. � 1.3 Pro'ect Descri tion 1 P �, The project site is located in an unincorporated area Riverside County. The vicinity map with the project site location is displayed in Figure 1. The development area is bound by the Pechanga Indian Reservation on the East, � Pechanga Road on the South, Pala Road on the West and Dear Hollow Road on the North. The proposed land uses for the development include �/a-acre single famity homes, multi-family apartments, and a high school. � � , � � � � Redhawk Traci No. 23065 March 1, 2001 Hydrologic Analysis 1 Garrett Group � � � � ��rl �' F � FIF �1> � � `!'�. �= -- --- - _ .__ __ 79 --- . _ _ _ - -- _ _ _---------- - ____ � �- - GF _ _ __ _ ,� � � �d ,-�, _.- i / ` ` TEMECULA CREEK $ q �<� RD. ��oQ � � A � � 1 �`��� � .o �. � �� CORD�BA ooQ � � � y �9 �' o ���r�t �1P ���y�. 1 �,O $ � 1 �d � ��t�` �2 � VALLEY �,0� Z �� V ALLEY v0��` A � Q � �+'� � � \ \ � � O`' d � 2 ��� ` � � � � � � \ �,� � � ��v � A � \ y 9yc � � ��`�� PROJECT . �,� . � SITE � ` . . . �� \ . � �; NflRTH VIC INITY �VIAP � NOT TO SCALE �� PLANNINO ■ DEBIGN ■ CONBTRUCTION FlGURE ■ ■ ■ 14M5 ALTON PAPoCWAY � � iiVrE, CAIFqNA 926B-20D C O N S U LT 1 N G oas.t/2asos • Fnx eao.o2e�r� •...�xom PI�TNSD uoEA M AWExM90M Of: PAGE DAIE 2 � � � � SECTION 2- ENGINEERING ANALYSIS AND METHODOLOGY � 2.1 Hydrology � ---- - �� ----- ��his - section - describes the watershed , procedures, and results of the hydrologic analyses. It is important to note that � the peak discharges described in this document were estimated for the following plan elements: � • The developed condition 10- and 100-year discharges were estimated for the design of the flood control infrastructure. The 10-year discharge shall be contained within the top of curb. The 100-year discharge shall be contained within the street right-of-way. • The 2-year/Water Quality Storm is estimated to design the diversion structures for the Water Quality Basins. � The design discharges developed as part of this study must be updated if land use or major watershed boundaries are changed as compared to the conditions used to develop this report. Flood control facilities (storm drains) will be designed using hydrologic information developed as part of the tract improvement plans. 2.1.1 Rational Method Hydrologic calculations to determine the 1a- and 100-y�ar design peak � discharges for tributary areas less than 300 to 500 acres are required to be performed using the Rational Method outlmed in the R�verside County Flood Control and Wafer Conservation �isfrict (RCFC&WCD) Hydrology Manual. � The Rational Method relates the peak discharge (Q, cfs) to the drainage area (A, acres), the rainfall intensity (i, in/hr), and the runoff coefficient (C): � Q = CIA � The 2-, 10-, and 100-year design discharges at intermediate points were computed by generating a hydrologic link-node model, using the Advanced Engineering Software (AES) release date 1/1/99, which divides the watershed into drainage sub-basins, each tributary to a concentration point or hydrologic � node, are linked together by a series of hydraulic conveyance processes. The following assumptions and guidelines were applied to the Rational Method: � Redhawk Tract No. 23065 March 1, 2001 Hydrologic Analysis 3 Garrett Group � � � 1 Infiltration rate is incorporated into the hydrology and is affected by the soil surface characteristics, cover type and quality, percent of impervious area, � and the antecedent moisture condition. 2 An Antecedent Moisture Condition (AMC) of II was utilized for the � analysis, which reflects the degree of ground saturation from previous rainfall events.

It is assumed the overland flow effects dominate the travel time hydraulics. Initial subareas were limited to less than 10 acres in size and � Isss than 1,000 feet in length per the RCFC&WCD using this procedure. 6 The 10- and 100-year peak discharge calculations for the post- development condition are included in the Technical Appendix and summari�ed in Table 1. � 7 The hydrology calculations assumed 100 percent of the 100-year surface runoff was intercepted at each inlet. �! 8 The Tatum Method was used to calculate a bulking factor of 1.1 and was applied to the offsite flows. Drainage Area "C" is bulked before bemg added to Drainage Area "B."

Figure 2 shows the Drainage Areas. � 2.2.2 H dro�o ic Soils Classification Y 9 � The Department of Agriculture, U.S. Soil Conservation Service, has performed general classification of the average soil runoff potential throughout the entire county. There are all four hydrologic soils groups within the study area, Soils A, B, C, and D. Soils A is considered having the highest infiltration rates and is found in the western part of the watershed. Soils D is considered to have the highest runoff potential and is found generally in the eastern part (offsite areas) i of the watershed. The dominant conservative soil type was assigned to each sub � area. A soils classification map of the area is provided in the technical appendix. �� 2.2.3 Vegetation Cover and Impervious Areas The existing watershed consists primarily of agricultural land, golf course, open � brush and sparse development. The watershed is assumed as 100 percent pervious under existing conditions. � Under the developed condition, impervious surfaces will be added. Impervious surtaces within the watershed reduce rainfall losses associated with soil infiltration. Average impervious cover values have been assigned to the project � land uses.

The AES computer program, using Riverside County methods, computes the time of concentration for each subarea. 2.3 Water Quality A hydrologic analysis was performed to estimate the volume of water assumed as the water quality volume for each water quality basin. Each water quality � basin has be.en sized to accommodate the volume of water to be treated, also referred to as the water quality capture volume. The numeric.sizing cri#eria - assumed for the sizing of the water quality basins are based on criteria defined by the California Regional Water Quality Control Board San Diego Region. Several BMP sizing criteria have been defined which may be applicable to � constructed BMPs within the San Diego region. One criteria used for sizing BMPs is defined as.... "The volume of runoff produced from each and every storm event up to and including a historical record-based reference 24-hour rainfall criterion for `treatment' (0.6 inch approximate average for the San Diego County area) that achieves approximately the same reduction in pollutant loads achieved by the 85th percentile 24-hour event." This criteria was used for sizing the water quality basins within the Redhawk project. 2.3.1 Basin Sizing The volume of runoff was calculated using the method prescribed in the Water Environment Federation Manual of Practice No. 23/ASCE Manual and Report on � Redhawk Tract No. 23065 March 1, 2001 � Hydrologic Analysis 8 Garrett Group � __ . . � Engineering Practice No. 87 — An Approach for Estimating Storm Water Quality Capfure Volume (Pg. 175). The analytical procedure is based on a simpie � transformation of each storm's volume of precipitation to a runoff volume using a coefficient of runoff. A third-order regression equation to calculate the runoff coefficient was derived for this transformation. The runoff coefficient is � calculated with the following equation. _ . __.__ -- - ___ _ _ _ _-- - -- __ _ _-- -. _ _. _ .. _ C= 0.8581�-0.781�+0.774i+0.04 � Where C = runoff coefficient, and � i = watershed imperviousness ratio. The following equation uses the prescribed precipitation depth of 0.6 inch and � relates it to the "maximized" detention volume. Po=(a'C) *P � Where Po = maximized detention volume determined using the volume capture � ratio as its basis, watershed inch; a= 24 hour drain time regression constant from least-squares analysis; C= watershed runoff coefficient; and � P = mean storm precipitation volume (0.6 inch), watershed inch. Table 4, Table 5, and Table 6 below summarize the water quality basin volumes � calculated using the procedure above. � '..

The runoff from the proposed developed areas will be routed through a water quality basin prior to being confluenced with the offsite flows. Diversion � structures and basins are to be designed to allow the larger storms to bypass the water quality basins. � Redhawk Tract No. 23065 March 1, 2001 � Hydrologic Analysis 10 Garrett Group � � SECTION 3 - SUMMARY � This hydrologic study provides guidance to the development of the project on � drainage and runoff management/water quality issues as individual phases are ------------ ---eonstr�eted-during the development-period-of-theproject� i-t�is-stedy�arjsis#s-of-------- ° ----- ---- two general components: � 1.

An estimate of the stormwater quality capture volume to be used in designing � the water quality basins. The design discharges developed as part of this study will be used to size the flood control and water quality facilities. Storm drain systems will be designed as � a part of the local tract improvements. � Runoff from the watershed will discharge into the Pala Road Channel currently under design by Lohr & Associates. Overflow from PEChanga Creek will also add to the project runoff discharging into the Pala Road Channel. � References � ASCE Manual and Re ort on En ineerin Practice No. 87 WEF Manual of P 9 9 , Practice No. 23, Urban Runoff Quality Management, 1998. � California Re ional Water Quali Control $oard San Die o Re ion Water 9 tY , 9 9 � Quality Control Basin Plan for the San Diego Basin (9). � Riverside o n FI od ontrol and Water Conservati Di t i t drolo C u ty o C on s r c, Hy gy Manual, 1978. � � � � � Redhawk Tract No. 2308b March 1, 2001 � HydrologicAnalysis � 1 GarrettGroup � � SECTION 4 - TECHNICAL APPENDIX � � � APPENDIX A- BACK-UP DATA AND TABLES APPENDIX B - HYDROLOGY CALCULATIONS (A�ES� � APPENDIX C = HYDROLOGY MAP � � � � � � � � � � � � Redhawk Tract No. 23065 March 1, 2001 � Hydrologic Ana/ysis 12 Garrett Group � � i � 1 . � APPENDIX A � � BACK-UP DATA AND TABLES � REDHAWK TRACT NO 23065 � Point Rainfall Data Soils Map Water Quality Basin Volume Calculations � Impervious Cover Table . .
