Marion County OREGON COMMUNITY DEVELOPMENT DEPARTM£NT NOT'rC]~ OF Dg'NT~,z ~V~UA~ON ~OR~ FOR ~ 0N-SITE SEWAOE DI~POS~ SYSTEM March 8, 1993 Tim Boyce 8535 SW seminole Rd. Tualatin, Oregon 97062 SUBJECT: SITE ~92-03911, Tz4S, R:lw, S~12 SITE ADDRESS: 14747 Albers Way NE, Aurora An evaluation has been made of the above described property proposed for installation of an on-site sewage disposal system. AS a result of that investigation, it has been determined that the site specified on your applica- tion does not qualify for a standard septic system or any of the alternative systems. The conditions on the site do not meet the minimum requirements of the Department of Environmental Quality On-Site Sewage Disposal Rules. These rules are specified in Oregon Administrative Rules, Chapter 340, Division 71, Sections lO0 through 600. COns~quently~ this site must be denied. The principal reasons for denial of this site are related to parcel size and setbacks and slopes. The followinq paragraphs outline the specific reasons for this denial. PARCEL SIZE 1. AND SETBACKS: There is insufficient area on the property for installation of an approved on-site septic system which will meet the setbacks as required in the D.Z.Q. rules. The setbacks which are of particular concern are circled on the attached sheet. Each lot or parcel must have sufficient usable area available to accon~odate an initial and replacement septic system. SLOPES: 1. The natural land slope in the area proposed for installation of the on-site sewage system is greater than forty-five (45) percent. 2. No septic system may be constructed on a slope greater than forty- five (45) percent. The maximum slope for a standard septic system is thirty (30} percent and the maximum slope for the alternative steep slope system is forty-five (45) percent. It should be noted that this study was done only in the area proposed on your application for on-site sewage disposal, within the boundaries of your proper- ty~ it is possible that soil conditions in a different area of the property may be different than those examined in the existing test pits. If you feel that better soil conditions may exist in another area of the property, additional test pits will be inspected with no additional charge. 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.
