I. EXCAVATION - The removal or displacement of soil above the ordinary high water
mark which results in the affected area being made subject to regular tidal inundation.
J. EXECUTIVE DIRECTOR - The Executive Director of the Department of Marine
Resources.
K. FAILED STRUCTURE - A structure that has deteriorated to the point that it no longer
provides the intended and original function.
L. FAILING STRUCTURE - A structure that has structural weaknesses but that still

Q. MEAN HIGH WATER - The arithmetic mean of all the high waters occurring in a
particular nineteen-year (19-year) tidal epoch period; or for a shorter period of time after
corrections are applied to the short term observations to reduce these values to the
equivalent nineteen-year (19-year) value.
R. MEAN LOW WATER - The arithmetic mean of all the low waters occurring in a
particular nineteen-year (19-year) tidal epoch period or for a shorter period of time after
corrections are applied to the short term observations to reduce these values to the
equivalent nineteen-year (19-year) value.
S. MISSISSIPPI COASTAL PROGRAM (PROGRAM) - The consolidated statement of
State policy in the coastal area, as prescribed by Miss. Code Ann. §57-15-1 et seq.,

U. ORDINARY HIGH WATER MARK (OHWM) - A mark on the shore determined by
the department staff, established by fluctuations in water level and indicated by physical
and biological characteristics including, but not limited to, water stains, changes in the
character of the soil, scour lines, presence of debris lines, changes in plant communities
and other appropriate means that consider the characteristics of the surrounding area. The
determination of OHWM shall not be made by the department staff during high tide
where the above referenced characteristics are not observable. OHWM is not the same as
mean high water and shall not be used for determination of the boundary between private
property and public trust tidelands or for any purpose other than regulated activity as
defined in this section.
V. PERSON - Any natural person, partnership, joint stock company, corporation,

only homeowners or tenants of the adjacent development. Private single-family and
multi-family piers with twelve (12) or fewer mooring spaces are compatible with a "G"
for general use designation. Private single-family and multi-family piers with more than
twelve (12) mooring spaces require a "C" for commercial use designation. Commercial
vessels may not be moored in a multi-family pier.
X. PUBLIC BEACH - Any beach which has been dedicated to the public or in which the

coastal wetlands that cause dumping, filling, or depositing in coastal wetlands.
AA. REPAIR - Restoring facilities or structures to their original condition, purpose, and
function.
BB. SENSITIVE COASTAL WETLANDS - Coastal Wetlands containing submerged

banks containing reef building organisms.
CC. SMA - A Special Management Area designated under Chapter 17.
DD. SUITABLE SITES FOR WATER DEPENDENT INDUSTRY - Those areas of land
which are suitable for the development of water dependent industry because of their

conditions and access to other means of transportation. The definition is limited to, but
does not necessarily include, waterfront sites owned by county port authorities,
development commissions and port and harbor commissions, and to areas that are now or
are later made to be within one thousand (1,000) feet of the centerline of any natural or
