Construction or operations under a building or special permit shall conform to any subsequent amendment of this bylaw unless the use or construction is commenced within a period of not more than six months after the issuance of the permit and, in cases involving construction, is continued through to completion as continuously and expeditiously as is reasonable.
C. 
Restoration. A lawfully existing nonconforming structure or use, if damaged or destroyed by fire or other accident, may be repaired or reconstructed within one year; provided, however, that such repair or reconstruction shall be within the same portion of the lot and shall conform to the extent possible with the requirements of the then-existing bylaw.

(2) 
With respect to either (i) conforming structures on legally preexisting nonconforming lots which comply with all existing setback, height and dimensional requirements, or (ii) legally preexisting nonconforming structures on conforming lots, changes, alterations and extensions may be approved by the Building Inspector without the need for a finding by the Board of Appeals, provided that such changes, alterations or extensions also comply with all existing setback, height, and dimensional requirements and do not exceed 1,000 square feet.

Procedure.

Upon its receipt of such application, the permit granting authority shall submit one copy thereof to the Select Board and one copy to either the Planning Board or the Board of Appeals, as the case may be, for its review and written recommendations. Each such Board shall make such recommendations as it deems appropriate and shall send copies thereof to the permit granting authority and the applicant.

AVERAGE LOWEST FINISHED GRADE
The average (mean) lowest elevation of the ground adjacent to all the exterior walls of a building. It is calculated by determining the lowest elevation adjacent to each wall, weighting that elevation by the length of its adjacent wall (multiplying the elevation in feet by the length of the wall in feet), and dividing the sum of all weighted elevation figures by the total length of all exterior walls. The elevation figure used may be the height above mean sea level (msl), elevation relative to the top of the concrete foundation, or some other appropriate fixed point in the discretion of the building inspector. See illustration below:
[Added 1996]
240 Average Lowest Finished Grade.tif
Low points at each wall (height above msl):
A = 100'
B = 90'
C = 90'
D = 95'
Calculation: weighted elevations:
A = 30 x 100 = 3000
B = 50 x 90 = 4,500
C = 30 x 90 = 2,700
D = 50 x 95 = 4,750
Total weighted elevation: 14,950
Total length of walls: 160
Average lowest finished grade: 14,950/160 = 93.44
