measures that control soil loss and reduce water quality degradation
caused by nutrients, animal waste, toxic substances and sediment.
Agricultural BMP's include, but are not limited to, strip cropping,

area located immediately landward of tidal waters (measured from the
mean high-water line), tributary streams in the critical area and
tidal wetlands and has a minimum width of 100 feet. The Buffer shall
be expanded beyond the minimum depth to include sensitive areas as
per requirements established in the Zoning Ordinance.

in a selected area or selected areas of the development tract so as
to provide natural habitat or other open space uses on the remainder.
COMMUNITY PIERS

similar residential areas and with condominium, apartment and other
multiple-family dwelling units. Private piers are excluded from this
definition.

Any of a number of structural and nonstructural methods or
techniques for controlling the erosion of shoreline areas. More specifically,
the term refers to:
(1)
Nonstructural: creation of an intertidal marsh
fringe channelward of the existing bank by one of the following methods:
(a)
Vegetation: planting an existing shore with
a wide band of vegetation.
(b)
Bank sloping/vegetation: sloping and planting
a nonwooded bank to manage tidal water contact, using structures to
contain sloped materials, if necessary.
(c)
Contained beach: filling along shore with sandy
materials, grading and containing the new beach to eliminate tidal
water contact with the bank.
(2)
Structural:
(a)
Revetment: facing laid on a sloping shore to
reduce wave energy and contain shore materials.
(b)
Bulkheads: excluded due to adverse impacts to
the near-shore marine environment, except in the following cases:
[1]
Where erosion impact is severe and high bluffs
and/or dense woodland preclude land access, bulkheads can be installed
by shallow-draft barge and pile driver.
[2]
In narrow, man-made lagoons for activities that
require frequent interchange between boats and land.
SOIL CONSERVATION AND WATER QUALITY PLANS
Land use plans for farms that show farmers how to make the
best possible use of their soil and water resources while protecting
and conserving those resources for the future. It is a document containing
a map and related plans that indicate:

waters of the state below the mean high-water line, affected by the
regular rise and fall of tide, and "private wetlands" defined as any
land not considered state wetlands bordering or lying beneath tidal
waters, that is subject to regular or periodic tidal action and supports
aquatic growth. Private wetlands includes wetlands transferred by
the state by a valid grant, lease, patent or grant confirmed by Article
5 of the Declaration of Rights of the Constitution to the extent of
the interest transferred. The term "regular or periodic tidal action"
means the rise and fall of the sea produced by the attraction of the
sun and moon uninfluenced by the wind or any other circumstance.

Topographic Quadrangle Maps (scale: 1:24,000) or on more detailed
maps or studies at the discretion of the local jurisdictions.
WATER-DEPENDENT FACILITIES
Structures or works associated with industrial, maritime,
recreational, educational or fisheries activities which the City of
Crisfield has determined require location at or near the shoreline
within the Buffer.
WILDLIFE CORRIDOR
A strip of land having vegetation that provides habitat and
a safe passageway for wildlife.
