The Floodplain District is established for the following purposes:
A. To promote the health, safety and welfare of the occupants of land
against the hazards of flooding.
B. To preserve and protect the streams and other watercourses in Weymouth
and its adjoining lands.
C. To protect the community against detrimental use and development
which cause increases in erosion, flood heights or flood velocities.
D. To minimize losses by provisions designed to restrict or prohibit
uses which are dangerous to health, safety or property due to water
or erosion hazards.
The following criteria shall apply to any special permit use
granted within the one-hundred-year floodplain:
A. All new construction and substantial improvements of residential
structures shall have the lowest portion of all structural members
supporting the lowest floor, including basement or cellar, elevated
at least one foot above the one-hundred-year-flood elevation.
[Amended May 1999 ATM by Art. 18, approved 8-19-1999]
B. All new construction and substantial improvements of nonresidential
structures shall be floodproofed at least to a point one foot above
the one-hundred-year flood elevation. "Floodproofed" shall mean watertight,
with walls substantially impermeable to the passage of water and structural
components having the capability of resisting hydrostatic loads and
the effect of buoyancy.
C. Within the Floodplain District, one-hundred-year flood elevations
shown on the approved Flood Insurance Rate Map shall govern. Where
the one-hundred-year flood elevation is not provided, the Planning
Board shall produce and maintain any already existing one-hundred-year
flood elevation data, and it shall be used to meet the above requirements.
D. All subdivision proposals must be designed to assure that:
[Amended May 1999 ATM by Art. 18, approved 8-19-1999; 6-18-2012 by Ord. No. 12-091]
(1)
Such proposals minimize flood damage;
(2)
All public utilities and facilities are located and constructed
to minimize or eliminate flood damage; and
(3)
Adequate drainage is provided to reduce exposure to flood hazards.
E. Within Zone AO on the FIRM, adequate drainage paths must be provided
around structures on slopes, to guide floodwaters around and away
from proposed structures.

Construction.
C. Inland Wetland Restriction, DEP, 302 CMR 6.00.
D. Coastal Wetlands Restriction, DEP, 302 CMR 4.00.
E. Minimum Requirements for Subsurface Disposal of Sanitary Sewerage,
DEP 310 CMR 15, Title 5.
