Mar!qn' County OREGON COMMUNITY D~'VELOPMI~NT [DEPARTMENT NOTICE OF DENIAL: EVALUATION REPORT FOR AN ON-SITE SEWAGE DISPO.~AL SYSTEM August 27, 1992 PHILIP @ DEBRA QUINTON-COX 3746 SW COMUS PORTLAND, OREGON 97219 SUBJECT: SITE ~92-450, T=10S, R:SE, S=01 SITE ADDRESS= 165 CLIFFORD AVENUE, DETROIT, OREGON 97342 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 100 through 600. consequently, this site must be denied. The principal reasons for denial of this site are related to parcel size and setbacks. The following paragraphs outline the specific reasons for this denial. PARCEL SIZE AND SETBACKS: 1. 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.E.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 acco~m~odate an initial and replacement septic system. ADDITIONAL cOMMENTS= We can re-consider this property with a detailed field stakeout to establish whether there may be enough area to construct any of the alternative septic systems. Refer to the enclosed stakeout procedure for details to prepare the site for re-evaluation. The property corners and property lines must be clearly flagged and strung for location. If you choose to prepare the property for re-evaluation, notify this office of your request in writing and within ninety (90) days of the initial site evaluation. The alternative SAND FILTER system appears most likely for re-consideration, because less drainfield is necessary. The required amount of drainline for each drainfield of the sand filter system for the proposed three bedroom residence is ninety (90) lineal feet. The amount of drainfield line for each drainfield of a standard system for the same residence is 225 lineal feet. The lines must be contoured to the natural landform surface, configured in serial distribution, with the drainline trenches limited to 24 inches deep minimum and 30 inches deep maximum. A list of licensed septic system installers is enclosed for your convenience. Any of these installers should be able to assist you in preparing the site for re-evaluation.
