All bikeways shall conform to current Federal Highway Administration standards. Where trails have been relocated or otherwise disturbed, the developer shall ensure that they are readily passable on foot or horseback.

not intended for preservation by the applicant shall have been removed
and disposed of in a manner and place satisfactory to the Board. Any
fire hazard shall be removed promptly to the satisfaction of the Fire
Chief. This section does not authorize violation of the soil stripping
provision of the Zoning Bylaw, as it does not authorize the removal, including severing
and stripping of soil loam, sand or gravel on such lot.
Any subdivision located in any part within an
area subject to flooding shall comply with the following:
A. Subdivision design shall be consistent with the need
to minimize flood damage within the flood-prone area, through use
of open space reservation, street profile design and drainage.
B. All public utilities and facilities, such as sewer,

For the purpose of protecting the safety, convenience

in the operation of motor vehicles, for securing safety in the case
of fire, flood, panic and other emergencies, under the authority of
MGL c. 41, § 81-M, as amended, the applicant or his successor
shall provide for the proper maintenance and repair of improvements
during the period of construction and until the town votes to accept
such improvements.
The applicant shall provide competent supervision
during the development of his subdivision. If at any time it becomes
apparent to the Superintendent of Public Works that the supervision
is not satisfactory, he may request of the Board that it order the
discontinuance of the development until competent supervision is provided.
If the proposed development contains hazardous
materials or underground storage tank(s), the location and extent shall be shown on the subdivision
plans. All remedial work required shall be performed in compliance
with all local, state and federal laws.
