DEDICATION. Includes, but is not limited to, a restrictive covenant, permanent easement and fee simple donation.
DUNE. An emergent mound, hill or ridge of sand, either bare or vegetated, located on land bordering the waters of the Gulf of Mexico. DUNES are naturally formed by the windward transport of sediment, but can also be created via man-made vegetated mounds.

(b) INDIRECT EFFECTS. Those impacts on beach use and access, on critical dune areas, or on dunes and dune vegetation seaward of a dune protection line which are caused by an action and are later in time or farther removed in distance than a direct effect, but are still reasonably foreseeable.

(2) EFFECTS and impacts as used in this chapter are synonymous.
(3) EFFECTS may be ecological (such as the effects on natural resources and on the components, structures and functioning of affected ecosystems), aesthetic, historic, cultural, economic, social or health, whether direct, indirect or cumulative.
ERODING AREA. A portion of the shoreline which is experiencing an historical erosion rate of greater than two feet per year based on published data of the University of Texas at Austin, Bureau of Economic Geology. The city may establish an eroding area boundary in beach and dune plans; this boundary shall be whichever distance landward of the line of vegetation is greater: 200 feet, or the distance determined by multiplying 50 years by the annual historical erosion rate (based on the most
recent data published by the University of Texas at Austin, Bureau of Economic Geology).
EROSION. The wearing away of land or the removal of beach and/or dune sediments by wave action, tidal currents, wave currents, drainage or wind. EROSION includes, but is not limited to, horizontal recession and scour and can be induced or aggravated by human activities.

FOREDUNES. The first clearly distinguishable, usually vegetated, stabilized large dunes encountered landward of the Gulf of Mexico. On some portions of the state Gulf Coast, FOREDUNES may also be large, unvegetated and unstabilized. Although they may be large and continuous, FOREDUNES are typically hummocky and discontinuous and may be interrupted by breaches and washover areas. FOREDUNES offer the first significant means of dissipating storm-generated wave and current energy issuing from the Gulf of Mexico. Because various heights and configurations of dunes may perform this function, no standardized physical description applies. FOREDUNES are distinguishable from surrounding dune types by their relative location and physical appearance.
FOREDUNE RIDGE. The high continuous line of dunes which are usually well-vegetated and rise sharply landward of the foredune area but may also rise directly from a flat, wave-cut beach immediately after a storm.
HABITABLE STRUCTURE PERIMETER or FOOTPRINT. The area of a lot covered by a structure used or usable for habitation. The HABITABLE STRUCTURE PERIMETER or FOOTPRINT does not include incidental projecting eaves, balconies, ground-level paving, landscaping, open recreational facilities (for example, pools and tennis courts) or other similar features.
HABITABLE STRUCTURES. Structures suitable for human habitation including, but not limited to, single or multi-family residences, hotels, condominium buildings and buildings for commercial purposes. Each building of a condominium regime is considered a separate habitable structure, but if a building is divided into apartments, then the entire building, not the individual apartments, is considered a SINGLE HABITABLE STRUCTURE. Additionally, a HABITABLE STRUCTURE includes porches, gazebos and other attached improvements.
INDUSTRIAL FACILITIES. Include, but are not limited to, those establishments listed in Part 1, Division D, Major Groups 20-39 and Part 1, Division E, Major Group 49 of the Standard Industrial Classification Manual as adopted by the Executive Office of the President, Office of Management and Budget (1987 ed.). However, for the purposes of this chapter, the establishments listed in Part 1,
Division D, Major Group 20, Industry Group Number 209, Industry Numbers 2091 and 2092 are not considered

LARGE-SCALE CONSTRUCTION. Construction activity greater than 5,000 square feet in area and habitable structures greater than two stories in height. Multiple-family habitable structures are typical of this type of construction.
LINE OF VEGETATION. The extreme seaward boundary of natural vegetation which spreads continuously inland. The LINE OF VEGETATION is typically used to determine the landward extent of the public beach.
MAN-MADE VEGETATED MOUND. A mound, hill or ridge of sand created by the deliberate placement of sand or sand trapping devices including sand fences, trees or brush and planted with dune vegetation.
MASTER PLAN. A plan developed by the applicant in consultation with the General Land Office, the Office of the Attorney General, the applicant or applicants, and the city, for the development of an area subject to the beach and dune rules, as identified in Tex. Administrative Code Title 31, Part 1, Chapter 15, Subchapter A, § 15.3. The MASTER PLAN shall fully describe in narrative form the proposed development and all proposed land and water uses, and shall include maps, drawings, and tables and other information, as needed. The MASTER PLAN must, at a minimum, fully describe the general geology and geography of the site, land and water use intensities, size and location of all buildings, structures and improvements, all vehicular and pedestrian access ways, and parking or storage facilities, location and design of utility systems, location and design of any erosion response structures, retaining walls or stormwater treatment management systems, and the schedule for all construction activities described in the MASTER PLAN. The MASTER PLAN shall comply with the Open Beaches Act, being Tex. Natural Resources Code, §§ 61.011 et seq. and the Dune Protection Act, being Tex. Natural Resources Code, §§ 63.001 et seq. The MASTER PLAN shall provide for overall compliance with the beach and dune rules, but may vary from the specific standards, means and methods provided in the beach and dune rules if the degree of dune protection and the public's right to safe and healthy use of and access to and from the public beach are preserved. If all impacts to dunes, dune vegetation and public beach use and access are accurately identified, the city shall not require permits or certificates for construction on the individual lots within the MASTER PLAN area. MASTER PLANS are intended to provide a comprehensive option for planning along the state coast.
MATERIAL CHANGES. Changes in project design, construction materials or construction methods or in the condition of the construction site which occur after an application is submitted to the city or after the city issues a permit or certificate. MATERIAL CHANGES are those additional or unanticipated changes which have caused or will cause adverse effects on dunes, dune vegetation or beach access and use, or exacerbation of erosion on or adjacent to the construction site.
MITIGATION SEQUENCE. The series of steps which must be taken if dunes and dune vegetation will be adversely affected. First, the adverse effects shall be avoided. Second, adverse effects shall be
minimized. Third, the dunes and dune vegetation adversely affected shall be repaired, restored or replaced. Fourth, the dunes and dune vegetation adversely affected shall be replaced or substituted to compensate for the adverse effects.
