PARCEL MAP 24085 HYDROLOGYIHYDRAULIC STUDY AREA Parcel Map 24085 property was initially a part of the Assessment District No. 155 (AD 155) Master Drainage Area Plan. AD-155 outlined a network of proposed storm drain improvement needed to protect development from flooding during the 100 year storm event. The purpose of this study is to evaluate the existing and proposed storm drain improvement and amend the improvements as needed to protect the proposed development. HYDROLOGY SUMMARY EXISTING CONDITION The easterly portion of PM 24085 below the 1026 elevation is located in the Murrieta Creek 100 year floodplain. On-site and off-site storm runoff under existing conditions discharge approximately 406 cfs into Murrieta Creek via a 48-inch culvert that is grossly deficient to convey any large magnitude storm and will cause local storm runoff to pond. DEVELOPED CONDITION The propose project will be protected from flooding by the construction of storm drain improvements depicted on the "Developed Condition Hydrology Map" and by elevating any future building sites above Murrieta Creek Floodplain elevation of 1026. LINE "C" - ZEVO DRIVE The updated hydrology for this area estimated a 100 year storm of runoff of 214.65 cfs versus the AD 155 and Parcel Map 21383 estimated 100 year storm runoff of 216.7 cfs. No revisions to existing Line "C"storm drain improvements will be I-I "? I I I I I I I I I I II I I I I I I I I ul required. (Line "C" has been constructed). LINE "A" - WINCHESTER ROAD Line "A" storm drain from Calle Patron northerly to a point northerly of Remington Avenue will be require to be constructed to protect Winchester road improvements. Ultimately Line" A" will discharge off-site and future TPM 28046 run-off into Murrieta Creek. As an interim measure until Winchester Road is constructed northerly it is proposed to discharge Line "A" storm runoff into the existing watercourse via an temporary earthen channel. See Improvement Plan for PM 24085- 4 for detail. LINE "B" -REMINGTON A VENUE/DIAl ROAD PM 24085 hydrology calculations estimate a total of 83 cfs storm runoff will be conveyed via surface street flow to the intersection of Diaz Road. Line "B" as depicted on the" Developed Condition Hydrology Map" will not be required until the future development of Tentative Parcel Map 24086. In the interim PM 24085 runoff will be discharged northerly into existing floodplain via culverts. The culverts are designed so they can easily be connected into the future Line "B" at the time of development ofTPM24086. 1-2 1\ I I , I I I I I I I I I I II I I '. .
