Phil,
In response to your emai|s, |'m not sure that | would recommend that the Planning Board to condition that the soil
testing be done prior to construction. I think it's going to have to be done in advance so that we know that the runoff
can all be recharged on site and how much area is going tobe required todoso. | agree that the soils on this site may
be particularly prone to sedimentation, so erosion controls should be used during testing.
Regarding my comment#3, an infiltration trench along the side of the driveway would be preferable topervious
pavement in terms of providing an opportunity to intercept any spills but it will have the same problem regarding slope.
Just as a reminder,the DEP Standards prohibit ANY stormvvater BMPsvvithin Zone A. | recognize that as a single family
home this project is not subject to the Standards, but it is something that all parties should at least be aware of. Your
design should both maximize the treatment provided and minimize the area of disturbance needed.
As far as the alternatives analysis (my comment#4) it is up to the Planning Board whether the one you did for the ZBA
suffices, or whether the option of smaller building footprint should also be considered.
Re comment#5 the total area of disturbance should be as small as possible. Whatever tightening up you can do should
be done and the owners should recognize that their view of the lake may be limited. The Planning Board or
Conservation Commission may also want to see a landscape plan for the property.
Let me know if you have any questions.

| have received your comment letter from Judy.
Comment 5. 1 did have the limit of work and clearing shown on the plan as a tree line. I will label it as limit of
clearing.
The area in front of the house has to be cleared for the driveway as well as the sewer installation and water line
installation. The opening at the street is only 37 feet and contains the water sewer and driveway. If you think it appropriate
I could reduce it to 20 feet allowing for 10 feet between the water and sewer and 5 feet beyond each line to allow for
construction. Your comments regarding landscaping will be added to the plan
1
Comment 6. We will add a note to the plan to prohibit copper gutters and downspouts.
Comment 7VVe will address maintenance ofstormwotersystems
Comment 8A construction sequence will beprovided
Comment 9. | will change the construction entrance to minimum 2 inch.
