If Gilford is 40 it will become 50 when the new standards pass. This is not a project killer but it is something to be aware of because you should try to avoid any outward expansion (upward would still be ok) on the portions inside 50 ft.
On a 1 acre lot you can build up to a total of:
- 8,712 sqft of impervious area with no need to agree to cutting restrictions or implement a stormwater management plan.
- 10,890 sqft of impervious area if you agree to protect and not remove any healthy trees and saplings within 50 ft of the reference line. (If there are not enough trees to meet the minimum buffer standards re-planting will be required but maintenance of existing/remaining open areas and the trimming of branches and pruning of shrubs down to 3 ft is still allowed.)
- 13,068 sqft of impervious area if you agree to protect and not remove any healthy trees and saplings within 50 ft of the reference line and inmplement an approve stormwater management plan.
Decks are considered to be impervious. You could use a surface that has enough openings at a size that would qualify as pervious, but personally I would hesistate to use those surfaces in areas that may be travelled by little fingers and toes. It would be the owners call...
