Taken from the COMPREHENSIVE SHORELAND PROTECTION ACT, section 483-B:9:

Starting from the northerly or easterly boundary of the property, and working along the shoreline, the waterfront buffer shall be divided into 50 by 50 foot segments. Within each segment a minimum combined tree and sapling score of at least 50 points shall be maintained. If for any reason there is insufficient area for a full segment, the number of points required to be maintained in that partial segment shall be proportional to that required of a full segment.
(i) Tree and sapling diameters shall be measured at 4 1/2 feet above the ground and are scored as follows:

Diameter Score:
1 inch to 6 inches - 1 Point
greater than 6 inches to 12 inches - 5 Points
greater than 12 inches -10 Points

(ii) Dead, diseased, or unsafe trees or saplings shall not be included in scoring.
(iii) If the total tree and sapling score in any 50 foot by 50 foot segment exceeds 50 points, then trees and saplings may be removed as long as the sum of the scores for the remaining trees and saplings in that segment does not total less than 50 points. Trees and saplings may be removed from partial segments provided that the sum of the scores for the remaining trees and saplings in that partial segment is equal to or greater than the proportional point requirement.
(iv) The department may approve applications pursuant to RSA 482-A that include the planting of native trees and saplings as necessary to at least maintain either the existing combined tree and sapling score or the minimum score required. The department shall not approve any application that would result in a combined tree and sapling score less than the minimum score required where the segment initially meets the minimum score or would result in any reduction of the combined tree and sapling score where the segment does not initially meet the minimum score.
