MCCO2�BS- KNUTSON REPORT ON SANITARY SEWERS FOR STUBBS BAY AREA, 1975_ � <br /> (CONT. ) <br /> The nearest potentially suitable drainfield site presently would be the <br /> . high land east of the Andromeda property. At this time, it is not known <br /> � whether this p�-operty could be acquired or at what price. <br /> I feel this proposal sti11 has merit, but costs would be sibnificantly <br /> higher than previously estimated, due to various factors . . <br /> D, CONCLUSIONS - M.4RII�A PROPERTY <br /> . 1. . Site Suitability " " <br /> a) The site is most suitable for a holding tank system which <br /> with proper design, installat�ion and maintenance would adequately <br /> • protect the public health by preventing possible ground or surface <br /> water contamination. <br /> b) Pending further investigation by parties unknown, the site. may <br /> be suitable for a mound system, which due to flooding hazard ' <br /> and fluctuating high water table in a sandy soil would have a <br /> - higher risk of potential ground or surface water contamination. <br /> ' c) The site is ,no.t suitable for a standard drainfield system. <br /> 2. Legal� Roadbloc.ks <br /> a) Orono code prohib its drainfield within 100-year flood plain zones , <br /> and within designated sheet flow areas . In effect, Orono code <br /> would prohibit any septic system or well on the property. <br /> z <br /> b) Pending determination of water table depths , Orono Code would <br /> prohibit a mound system on parts of the lot and sets standards <br /> for drainfield and tank location and construction. <br /> . c) State WPC-40 standards require minimum height of drainfield • <br /> - above 10-year flood elevation, and set standards for location <br /> . � and construction. . , . <br />
