Re: Area Variance No. 71-1994/Godnick
Dear Mr. Martin:
Rist-Frost Associates has reviewed the Site Plans - Proposed Variance drawing,
along with the stormwater runoff calculations, received January 4, 1995. We have
the following engineering comments:
1. If possible, the portion of existing water line in the lake should be
considered for reuse ('to minimize in-lake disturbance) . If not, steps to
prevent excessive shore area disturbance are recommended. The proposed
water line should be 25 feet from the house sewer.
2. The on site disposal system for the existing structure (an assumed
seasonal use camp) is a series of holding tanks with 3,000 gallon
capacity. The Town sewer ordinance requires a 3,500 gallon capacity for
a three bedroom usage, with a series of tank level alarms ( it is not known
if an alarm system is installed or proposed) . Although the ordinance
prohibits holding tanks for year round permanent use, it allows continuing
use of a properly functioning pre-existing system, provided no changes to
it are proposed.
3. The applicant should show the measures proposed for sediment and erosion
control during construction and prior to site stabilization, to prevent
sediment discharges to lake or adjoining property.
4. The applicant is proposing to infiltrate the additional runoff caused by
the difference in impermeable area of the existing site vs. the proposed
site. (The percolation rate used for drywell design should be noted as
either an actual test result or an estimate. ) However, due to the
proposed removal of a number of trees in the immediate vicinity of the
house and driveway, it would be appropriate to design for additional
runoff control (foliage increases the effective permeability of ground
surfaces) . The method and direction of roof runoff discharges should be
indicated.

Planning Staff has indicated they and the Board will examine the Zoning Board's
general concern of the project visibility. We can also, if desired, review that
aspect of the project, but would need additional site data and a site visit to
properly comment.
Please call if you have any questions.
Very truly yours,
RIST-FROST ASSOCIATES, P.C.
