INTR�DUCTI�N '1.1 BACKGROUND Michael Baker fnternationaf has been retained by Generations HC, LLC to prepare an onsife drainage study for PM 3fi4fi'[ in the Paseo ❑el Sol planning area No. 38. Planning Application '�4- 2s9fi proposes a medical office and health �are taci�ities project named Temecula Hea[thcare Center. The project site is Iocated in the City o€Temecula, California and is bounded by De Portala Road t� the north, Campanula Way to the east, and the Existing shopping cenfer to the south and the west�see Figure 1}. The sife is currently �acant and was pre�iously rough graded with a sing[e pad. It drains to existing drainage facilit3es near the Northwest and Southwest corn�rs af the property. This property drains fo a channellbasin adjacent to the west of the property. The parkway franting the property in De Portola Road and Campanula Way drain to existing drainage fac��ities iocated along Campanula Way and �e Portola Road. They are not pa�t of#his study. , 1.2 QBJECTIVE The abjecti�es of fhis drainage study are the following: • ❑elineate the onsite drainage areas tribu�ary to the proposed storm drain in�ets using #he Precise Grading P�ans. � Based on the propased drainage patterns, ground slope, land use and so�l type, and following the criteria and procedures described in the Ri�erside County Hydrology Manual, perform hydrologi� calculations to determEne the 1�- and '���-year �eveloped Condition discharges. ■ Compare the resulfs of the analysis with pre�ious studies to ensure that the proposed starm drain facilities are compatible wi�h the existing downstream improvements. The �00-year discharge leaving the site should not exceed the discharge shown on the appro�ed Storm Drain plans far the existing 48" RCP within P.M. 28384. ■ Comply with the NPDES requiremen�s that all impervivus areas drain to an appropriate Best Management Practice �BMP} or equapy effecti�� alt�rnat��e. �dentEfy and size fhe BMP in order to meet the NPDES requirements. This wi�l be addressed in a separate Prelim�nary Proj�ct Specific Water Quafity management Plan (WQMP}. 2 �lh+Y�+.!ra• �r...����-.�,�y,a'' �:ti:; �al'L :�: ;�2;���. .i ,'Y:µ.

HYDR�L�GICIHYDRAIJLIC 11AETH�D�L�CY The methodology pr�sented in this s�udy is in compliance with the RCFC&WCD 1978 Hydrology Manual (Reference 5}, hereinafter referred to as the Manual}. � Model Descripfiions -The [ntegrated Rational Mefhod Hydrology System Model Version 8.�, dated January 1, 2�1'i, (Reference S}within the Ad�anced Engineering Systems Sofiware (AES} was used to generate the peak '1��-year onsite flows. Soit Type - The Manuaf utilizes the 5oil Conservation Ser►�ice {SCS} soil cfassification system, which classifies soils into f�ur �4} hydrological soil groups [HSG}: A through D, with D being the least impervious. Plate C-1.52 of the Manua! and the Hydrologic Sai[s Group Report from The Natural Resources Conservation Service are includ�d in Appendix D. Accarding to this r�port, this project is located within HSG "B"." For this rep�rt, H5G "B" was conservati�efy used in the hydrologic madels be�ause the site was previously graded and compacted. De►►elopment Type- The proposed de�elapment model was based on commercial for areas with higher imperv'tous areas. In��1151ty- Standard intensity-duration curve data was taken from the Hydrology Manual Plate 0-4.1 (4 of fi} Murriefa-Temecula and Rancho California areas. For the '[�fl-year analysis, the data speci#ies a 1��-year 1�-minute rainfall intensity o�3.48 incheslhour and 1��-year fiD-minute rainfalf intensify �.30 incheslhour. For the 1�-year anafysis, the data specifies a '10-year '10- minufe rainfall intensity of 2.3fi incheslhour and a 1 D-year 6� minute rainfall intensity of 0.88 incheslhour. Drainage Areas and Fl�w Patterns - The drainage areas and flow patterns for exisfing and proposed conditions were determined using the de�eloped condition topography {Cadd} and the data a�ailahle per the Precise Grading Plan, respecti�ely. The areas were measured using the compufer capahili#ies of AutaCAa. III.

M. Na. 28384, A review of the P.M. No. 28384 Storm Drain Plan & Pr�file was pertormed to determine the aflowable Q'��Q capacity far the existing storm drain system. The plans indicate � that the inlet o€storm drain [ine 6 was designed �or an inferim flow af 87.1 CFS and ultimate flow � of 3�.D CFS. The interim flaws were larger because the system far PM 28384 was constructed prior to the storm drain system in Margarita Road, De Por�oEa Road and Campanula Way {Line W-Stages III and iV}, and line B accepted some ofF site flows prior to the constru�tion o€ � Campanula Way. Line W con�eys now all flows that discharge to Campanula Road and de Portola, therefore there are n❑ offsite tributary f�ows #a the pro�ect site. The Q'�0� flows lea�ing the proposed si#e are 21.9 CFS. They do not exceed the interim or ult�mate capacity of the Storm ❑rain line B, as a result, onsite detention is not needed.

Soils are assigned to one vf fvur groups according to the rate af water infiltration when the svils are not protected by vegetation,are thoroughly wet, and recei�e precip�ta#ion ' from long-duration storms. � The sails�n the United Sta�es are assign�d to four groups �A, 6, C, and ❑}and � �hree dual classes �AID, 61�, and GID}.The groups are defined as folfows: � Group A. 5oils having a high inf[tration rate{Ivw runoff patential}when thoroughly ; wet. These consist mainly of deep, welf drained�o excessive[y drained sands❑r gra�elly sands. These soils ha�e a high rate of water transmission, Group B. 5oils ha�ing a moderate infilfration rate when thoraughly wet. These cvnsist chiefly vf moderately deep or deep, modera�ely well drained or we[[drained soils that ha�e moderately fine texture to mvderately coarse fexture. These soils ha�e a moderate rate of water transmission. Group C. Soils having a slow infi[tration rate when thvrvughly wet.These consist chiefly af soils ha�ing a Eayer that impedes#he downward mo�ement of water❑r soils vf mvderately fine texture or fine texture.These soils have a slow rate af watet transmission. , Group D.

These soils have a�ery slow rate of water transmission. It a soil is assigned to a dua[ hydrologic graup {AIO, BIO, ❑r CID}, the frst le�ter is for drained areas and the sec�nd is for undrained areas. anly the svils that in their natura[ condition are in group D are assigned to dual classes.
