#626 (shuck Van Eeckhout Pays 2 scale site evaluation for each lot. Except for sot •1, the testing report indicates potentially buildable lots. My recommendation at this point is that the applicant first submit a site evaluation report showinq that lot 4 has suit- able soils for a drainfield system,. If this is not possible, a lot rearrangement may be zzec:scary. Secondly, the remainder of the testing (4 perc tests, 2 borings per lot) must be sub- mitted. (The preliminary testing satisfies Or.ono's require- ments for at-, "alternate drainfield area". Ref. Orono Design Manual, Part II, Section 3, and Part III, Section :.) Although I indicated to the applicant that the preliminary test- ing would be sufficient to obtain preliminary approval (assum- ing results were satisfactory), this is against_ established policies which have been reinforced by recent applications to the City. During the subdivision prcce,s, in many cases the drainfield site location Bete -mines the number of lots and the house locations, i.e. only a small portion of the proposed lot is suitable for drainfield. If the proposed 'house location decided upon by a prospective buyer encroaches on the tested sites, either the house location must be moved or further test- ing done to find a dif_'erent suitable drainfield site. A review of the building years 1978-1980 indicates that of 26 pre -tested building sites built upon, 6 required further testinu due to house location encroachment on rested drainfield sites. Four others had to make house location adjustments to stay off the only feasible drainfield sites on the lot. Th` remainder were able to make use of the tested sites. The main argument against preliminary testing; is that it is impossible to determine where a prospective buyer may want to locate his house on a lot, hence testing may have to be re- peated. However, for the City to allow creation of !ots with- out proven septic system capabilities can became c,)stlj and in direct opposition to the City's Comprehensive Plan, if numerous lets can't support a system and can't be built upon. Also, if only -partial testing_ is done, and the lots are sold as "already tested", staff my be pressured into issuing per- mits for s7stems with undesirable or inknown soil conditions. To conclude, in my op.nion the requirement to 1,avc. testing done on new subdivisions is valid, since it furthers the pur- poses and policies stated in the City's Corrprehensiv,. Man. This pre -testing of lots has proven to be adnq uate in -4i4 of the lots built upon so far. In this applicati,)n, since soils on certain proposed lots are indeed marginal. for drainfield use, all testing should be completed prior to prelin.Lnary ap- pr teal, since lot lines may have to be rearrancled to include st..t.able sites for drainfield? use.
