Marion County OREGON CO,/VIM U NI"rY i)~cVELOPMENT O~,PAR, TM£N'F Jack Hogan 2575 SW Palisades Crs~t Dr. Lake O~wego, Oregon 9703~ SUBJECT~ SITE ~94-00756, T:4S~ R:lw, $;11 8%TE ADDP~SS~ 14397 Keil Rd. N~, Aurora An evaluation has been made o~ ~he above described property proposed for installation of ab on-site sewage disposal system. As a result of that investigation, it has been determined that the sits Specified O~ your applica- tion does not qualify for a standard septic ~y~tem or any of the alternative systems. The conditions on =he site do not s~et the minimu~ ~e~uir~nts of the Department of Enviro~eetal Quali~y On-Site Sewage Disposal Rules. These rules are specified in Oregon Administrative Ruins, Chapter 340~ Division 71, sections 100 through 600. Consequently, thi~ ~ite must be ~enfe~. The principal reasons fo~ denial of this site are related to water tables. The following paragraphs outline the specific reasons for this denial. WATER TABLZS= 1. A water table, as indicated by conditioas associated with satura- tion, was observed on the property as follows~ a. Evidenoe of a temno~arv., water table was obse=ve~ at 1--0 ~ bolow the ground surpass, Thess measurements were to the depth Of the soil mottling or tO the actual depth of a~ observed water table. 2. The above conditions do ~Ot meet the minimum D.E.Q. rules ps,rain- ing to standard and alternative sewag~ ~ystems, The minimum requimements are listed below: a. A temDor.a~v ~roundwat. er tabl~ cannot be le~s than 24 inches below the groun~ surface rom installation of a standard septic system or .l~inches for installation of any of the alternative systems. It should be noted that this study was done 0sly in the area prope~ed on you~ application for on-site sewage disposal. Within t~e boundaries of your proper- ty, it is possible that soil ~onditions in a different area of the property may b~ differen~ than those examined in the existing test pits. If you feel that better soil conditions may exis~ in another area of the property, additional test bits will be inspected with no additional uharg~. Prepare and submit a new site plan showing the new area proposed for evaluation. Notify this office of your request in writing and within ninety (90) days of the initial site evaluation. ADDITIONAL COFR<ENTS: Water was 0bserv~d in both te~t pits at 0" to 6" during the ~irst visit to the property, subsequent visits found the water table at 10" below the surface, Rainfall, at Salem, is approximat~ky 12 inches below normal for the current weather yea~. Since the land is basically flat, i~ is doubtful that soil conditions will vary significantly on the p=0perty.
