I. EXHIBIT ___ �--- TO: Jeanne A. Mabusth, Zoning Administrator FROM: Michael P. Gaffron, Septic System Inspector DATE: January 17, 1983 SUBJECT: #722, 4740 Bayside Road, Brent Primus, Site Evaluation for Septic Systems This is an existing 1+ Acre Lot with existing house and septic system which was repaired in 1980. Testing was done to show that the lot is large enough to support all future septic system needs. Testing was done at a site with 10-15% slopes. Perc Rates averaged 27MPI. No indication of the presence or absence of mottling was given, as is required in the Orono Design Manual. The boring log does indicate "multi -colored clay" at shal.lnw depth, which may or may not be mott- ling. I was not able to obtain samples to prruse since the holes had been filled in. However, should a perched seasonal water table actually exist on the site at some time, the tested site would not be suitable for a mound due to the slope. In my opinion, flat land north of the property line should be added to the lot in an amount of at least 1/4 acre±. The strip 218' wide by 49' deep, continueing the rear lot line of parcel 2410 (see sketch) would be suitable. Adding land west of the existing parcel would be of little value for septic system due to slopes. I would further recommend that the lot be brought up to a 2.0 .icre minimum size if possible, which is the standard for unsewered lots in Orono. Please note that according to the legal description on Dunn's deed, their north boundary is 226 feet from the center of the road subject to a 33' road easement, hence the ictual existing lot dimensions for zoning purposes are (226-33) = 193' X 2181(or 2321dependinq on what is taken as the actual width of the west 112 of the SW1/4 of the SW1/4) which is about .97 acre. Also, the legal description in the tax records for parcel 2440 goes 253' north from the center of the road, so a (253'-226') = 27' discrepancy exists between parcels 2430 and 2440, as shown on sketch "A" attached. Assuming Dunn's deed description is correct, the existing port., line is about 46' north of the barn, and I suspect that the existing system is within existing lot lines, but may not meet a 10' setback.
