        A. MAINTENANCE OF A WATERFRONT BUFFER

1.      The waterfront buffer shall be those protected shorelands within 50 feet of the reference line. The purpose of this buffer shall be to protect the quality of public waters while allowing homeowner discretion with regard to water access, safety, viewscape maintenance, and lot design.
2.      Within the waterfront buffer all of the following prohibitions and limitations shall apply:
(a) No chemicals shall be applied, including pesticides or herbicides of any kind except as allowed under special permit issued by the division of pesticide control under rules adopted by the pesticide control board under RSA 541-A, or fertilizers of any kind except those specified in RSA 483-B:9, II(d).
(b) Rocks and stumps and their root systems shall be left intact in the ground unless removal is specifically approved by the department, pursuant to RSA 482-A or RSA 483-B:11, II.
(c) No natural ground cover shall be removed except as necessary for a foot path to water as provided under RSA 483-B:9, V(a)(2)(D)(viii), cutting those portions that have grown over 3 feet in height for the purpose of providing a view, or as specifically approved by the department, pursuant to RSA 482-A or 483-B:11, II.
(d) 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.
1. 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
        greater than 6 inches to 12 inches = 5
        greater than 12 inches = 10
2. Dead, diseased, or unsafe trees or saplings shall not be included in scoring.
3. 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.
4. 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.
5. Owners of lots that were legally developed prior to July 1, 2008 may maintain but not enlarge cleared areas, including but not limited to existing lawns and beaches, within the waterfront buffer. Conversion to or planting of cleared areas with native species of ground cover, shrubs, saplings, and trees is encouraged but shall not be required unless it is necessary to meet the requirements of subparagraphs (g)(2) or (g)(3), or RSA 483-B:11, II.
6. Normal trimming, pruning, and thinning of branches to the extent necessary to protect structures, maintain clearances, and provide views is permitted. Trimming, pruning, and thinning of branches for the purpose of providing views shall be limited to the bottom 1/2 of the trees or saplings.
7. When necessary for the completion of construction activities permitted in accordance with RSA 483-B:6, a temporary 12 foot wide access path shall be allowed. The access path shall be completely restored and replanted with native vegetation upon completion of construction except as allowed under subparagraph (8.) below.

The first 50 feet of this buffer is designated the waterfront buffer and is subject to the additional requirements of subparagraph (7.A.). The purpose of this buffer shall be to protect the quality of public waters by minimizing erosion, preventing siltation and turbidity, stabilizing soils, preventing excess nutrients and chemical pollution, maintaining natural water temperatures, maintaining a healthy tree canopy and understory, preserving fish, bird and wildlife habitat, and respecting the overall natural condition of the protected shoreland.
2.  Within the natural woodland buffer of a given lot:
(a)
1. For lots with one-half acre or less of land within the natural woodland buffer, the vegetation within at least 25 percent of the area outside the waterfront buffer shall be maintained in an unaltered state. Owners of lots legally developed prior to July 1, 2008 that do not comply with this standard are encouraged to, but shall not be required to, increase the percentage of area maintained in an unaltered state. The percentage of area maintained in an unaltered state on nonconforming lots shall not be decreased.
2. For lots with greater than one-half acre of land within the natural woodland buffer, the vegetation within at least 50 percent of the area outside the waterfront buffer, exclusive of impervious surfaces, shall be maintained in an unaltered state. Owners of lots legally developed prior to July 1, 2008 that do not comply with this standard are encouraged to, but shall not be required to, increase the percentage of area maintained in an unaltered state. The percentage of area maintained in an unaltered state on nonconforming lots shall not be decreased.
