EXHIBIT 1 TO: Jeanne A. Mabusth, Zoning Admin FROM: Michael P. Gaffron, Septic Syst, p.-2ctor DATE: January 14, 1983 SUBJECT: #723, 4520 Bayside Road, Brent Primus Site Evaluation for Septic Systems. This application is f,)r three 5+ acre lots, one of which requires soil testing due to the proliferation of steep slopes and wetlands. Tests on this Lot 1 failed to indicate suitable percolation rates for use as drain - field. This parcel was subsequently expanded to include the existing house and septic system on the adjacent proposed Lot 2, hence the new L;:t 2 (and Lot 3) are vacant land. Testing was performed to locate a suitable site for an alternate system for the existing house. This testing was done directly north of the house approximately 20' from an existing but apparently inadequate well. This site could be used only after the existing well is properly abandoned and filled. Percolation rates encountered at this site were 27 MPI and 5-6 MPI. Testing done on the west site of the shed in 1977 (about 190' from the recent testing) indicate an average perc rate of 36 MPI. Neither testing report indicates the presence or absence of rr3ttlinq at the proposed site although both stated that no water was encountered. My inspection of the site and soil samples obs,!rved indicate that slight mottling was present at some depth; However, it appears that should a mound system be ►equired at some future date, suitable flat area exists on this site so that a mound can be located. The existing system for the house was repaired in 1977 and appears to be in working condition. Note that the test report on the original I,ot 1 did indicate soils with mottling at depth of 1.5' to 4'. The report indicated that no water percolated at this site. The developer took ap• -opriate action in re-rranging lot lines. The new lots 2 and 3 are both larger than 5 acres, and need not be tested until developed. I recommend that. the proposal be approved.
