I - Industrial
The projeot includes the development of an aLIto wrecki ng yard Warned, Yet m Auto Recycl ing,
on liot -64300900200. Development will include 4 sEructu res to be used for office space, storage
and general shoWmainten ant -e space. �onstructi on will also i nol ude onsite ctustome r parking,
gravel ed a nd paved veh isle Storage Ys rds, grater, newer, and power nervi ce, slormwais r
faci Iities. 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.
