This chapter shall be applicable to any situation involving any disturbance to the terrain, topsoil or vegetative ground cover upon any property within the Town of Portsmouth, after determination of applicability by the Building Official based upon criteria set forth in §
320-3A below. Compliance with the requirements as described herein shall not be construed to relieve the owner/applicant of any obligations to obtain necessary state or federal permits.
Maintenance of all erosion and sediment control devices under
this chapter shall be the responsibility of the owner. The erosion
and sediment control devices shall be maintained in good condition
and working order on a continuing basis. Watercourses originating
and located completely on private property shall be the responsibility
of the owner to their point of open discharge at the property line
or at a communal watercourse within the property.
Neither approval of an erosion and sediment control plan nor
compliance with any conditions of this chapter shall relieve the owner/applicant
from any responsibility for damage to persons or property, nor impose
any liability upon the Town for damages to persons or property, such
as road beams, curbs, catch basins, pedestals, bonds, road improvements,
etc.
If, at any stage, the work in progress and/or completed under the terms of an approved erosion and sediment control plan does not conform to the plan, a written notice from the Building Official to comply shall be transmitted by certified mail to the owner. The notice shall set forth the nature of the temporary and permanent corrections required and the time limit within which corrections shall be completed as set forth in §
320-12B. Failure to comply with the required corrections within the specified time limit shall be considered in violation of this chapter, in which case the performance bond or cash or negotiable securities deposit shall be subject to notice of default, in accordance with §
320-6B and
