Planned improvements are separated into the "northerly site" development of an existing graded pad off Vancouver Street, and the "southerly site" construction of additional parking for the dog park and future trail. The existing graded pad at the northerly site drains southerly to the natural canyon . Flows from the pad into the canyon have resulted in erosion at the edge of the graded pad. To control erosion of canyon and avoid impacts of constructing a storm drain to the bottom of the canyon , the proposed design diverts 1.6 acres of the graded area and drains it into the existing storm drain in Vancouver Street. Approximately 0.3 acres of the proposed park area continues to drain westerly. These flows will be routed into percolation pits to avoid direct discharge to and erosion in the natural open space. Stormwater from the paved parking lot at the southerly site will be directed through a vegetated swale to filter pollutants out of the stormwater before they enter the storm drain system. Proposed drainage improvements include the construction of small-diameter PVC storm drains, with grated inlets. Runoff is by sheet flow, picked up by vegetated swales, which drain into grated inlets. ■ 200-scale GIS topographic mapping ■ San Diego County Hydrology Manual (Draft), Sept. 2001 ■ Drawing 189-5 Improvement Plans for CT 74-4 ■ Drawing 189-5A Grading Plans for CT 7 4-4 ■ ASCE Manual and Report on Engineering Practice No. 87, Urban Runoff Quality Management ■ King's Handbook of Hydraulics ■ Project Grading Plans Calculations indicate that the development of the northerly site and the resultant diversion of 1.6 acres into the existing storm drain will increase the 100-yr. runoff by 3 c.f.s. (8%). The existing storm drain has sufficient capacity for the minor increase in flow, and drains into an existing detention basin which will serve to mitigate the effects of the increase. Drainage Study LARWIN PARK CUP 02-23 The construction of the small parking area off Vancouver Street will require relocation of the existing curb inlet. Since the inlet is at the low point in the street, a slotted drain in the gutter is proposed in conjunction with a new curb inlet to the north of the new driveway. The onsite inlets and storm drain pipes have been sized to handle the 100-yr. storm event. The bio swale to treat the parking lot runoff has been sized in accordance with the flow- based criteria of Regional Water Quality Control Board Order No. 2001-01. 2 GVP CONSULTANTS 3764 Cavern Place CARLSBAD, CA 92008-6585 Ph (760) 720-0500 Fax (760) 720-2282 gvanpeski@home.com ..... cvP c::,z--z:3 SHEET NO. ___ ~-----OF I (p CALCULATEDBV _ _,G,~IR_· ----DATE 5·8,03 CHECKEDBV ________ DATE _____ _ SCALE ::: :~C~~:::.•.i·@·=i·•·······~···•.~.' .. ·.·.V!l'.· ' ........ -.:~.··.· .. ·.··D·····'·!·f·Cl·····•··:·'···.··~.·.~ ... ·.·.·.t.~.· .. ·.·•.D.•.' .•. ·.~.~2ti:~I:E!~~ .~br20~ l\O~.~n.~ .
