I~berg~ On April 5, 1982~ I ma~e preliminary soil ~¢aluations in regard to your proposal to develop an RV park adjacen~ to the [~nald/I-5 !hi,Change. As proposed, the RV park will be located on a 16.40 acre par0el (tax account ~40316-935) and the sewage syst~m~ will be located on the adjoining 11.45 acre parcel (ta~ account ~4 0746-000). Ba~ed on my soil evaluations, you~property d~es not qualify for installation of a standard on-site sewag~.~.~s~s~l syste~, ~ue ~o hiqh temporarily perched ground%raters which occur ~ing ~w~.ter. Yo~r site appears to qualify for an approved alt~rnative we ~all t/%e "~.:?le de~ater~lg system". I understa~dyou have retaine~r. Joe Pe~rovich of S~£1MSewage Consultants. F~. Petrovich is familiar with the design requi~e~aents of this type of system and can prepare the n~cessary plans. In r~¢t~ the collection ~-stem, septic tank, a~d dosi~ sump, these plans must be prepared by an engineer licensed in the Stat~ of Oregon. To says time and expedite our review, perhaps Mr. Petrovich could coordinate with the engineer you will use se only one sst of plans is sul~mitt~. There are s~me special it,s ~at need to be addressed: Before we can issue a feasibility approval, preliminary plans need to be submitted ~t will add, ess the following~ A hydraulic profile and cross-section of the proposed tile dewaterin~ syste~. This must show that proper depth and grade can be maintained (66 inches minimum in the disposal area with a grade of .2 to .4 feet of fall per 100 feet) to thu point of discharge.
