F rontage im prove ments are proposed, but MI I be deferred until required by the City. P roposed F I ow Control I rnprevements The flow control faoilifies consist of biopatention +-ells, infiltration trenches and infiltration cells. Test pits dug at the facil its+ I ocations revea led i nfrltration rates more than 1 -D0 irVhr. For design pu rposes, stormwater favi liti es we re modeled with 20 i nft. The Soils report can be found i n Appendix #2 of this document. Proposed Water Quality Irn provem gnts The water quality faoil iliss consist of bioretention Cells. The bioretention cells are designed to treat 91 % of the runoff profile. Thi bio rete ration cel Is utilFze a 12 in1hr design infi Itration rate with a Ksat safety factor of 4. Proposed Co nveyan ce system The proposed oonveyance systems will oonsi st of Type I catch basins and conveya nce pipe in various sizes to distribute stormwater to the proposed stonywvate r facilities. Proposed Discharge Location The project site will i nfi Itrete al I run oft at the proposed infilitration trencheskells. Downstream Condition The site contains a ridge run rting SE to NW. The ridge effectively splits the site with stormwater 105 Drainage Report 1-2 naturally droinl rig to the eastM. est boundaries. The proposed Improvements will have no effect on the existing oond Itlons as runoff will be contained on-site. Given the sites native well- drai ning soils Ft is likely that stermwater presently is i of Itrated before Ieavi ng the site. Onsite Soils and Goo logy An on -s Ite soils report was oom pleted for this project pito be Pa m el I Engi neerin g, LLC. A copy of the report is I ncluded in Append ix 2 of thi s docu merit. The report stated that infiltration on -5 ike is feasible with ca loulated infdltrati on rates exceeding 100 in1hr. The repo rt recom me nds a design infiltration of 20 i rVhr be used. Based upon this information the storm des ig n conte pt of infiltration was selected. 18025 Drainage Report 1-� PART 2 — SITE OEVrzLOPMENT LAYOUT Project Topog rap by The site topography i s nearly level to ge ntly $ to ping.
