TO: Jeanne A. Mabusth, Zoninq Administrator FROM: Michael P. Gaffron, Septic Systems Inspector DATE: April 6, 1981 SUBJECT: #609, Subdivision, Ruxton Strong, 420 Brown ?toad South Septic System/soil Testing Review On March 31, 1981, I inspected the Strong property to review the existing septic system and the proposed drainfield sites on the 2 new lots to be created. Lot 1. This lot contains the existing residence on about 1.5 contiguous dry acres, separated from the remainder of the dry land by a 1+ acre wetland. The house and well are situated so as to leave suitable area for a replacement drainfield. The non-contiguous 0.5 acre dry land has no realistic use as future drainfield. The existing septic system consists of 2 concrete tanks and an unknown amount of drainfield. I noted that the 2nd tank had what acpeared to be a hose (attached to a pump?) leadinq to the wetlands, with with 3 wooden support structure extending the hose into the wetlands. This leads one to surmise that the Strongs may be pumping sewage into the wetland, which is a violation of the on -site ordinance. The system appears to need some attention and I would recommend that subdivision approval include a stipulation that the existing system be suitably repaired/upgraded to City standards. Lot 2. This lot is quite sloped and contains some area not suited for drainfield due to steep slopes. The tested drainfield sites indicate fair soils for drainfield, but this location also appears to lie directly in the most likely driveway access from the cul-de-sac. I ,Aould recommend approval of this lot as -is, but the applicant should be forewarned that should the driveway or house location encroach on the tested drainfield sites, retestirq would bo reciuired at the time a buildinq permit is requested. Lot 3. This lot has an ample area of fair soils for use as drainfield. house location should not nose any maior problems.
