(a) Act shall mean the Tidal Wetlands Act (article 25 of the Environmental Conservation Law, as from time to time amended).
(b) Alter shall mean the performing of any activity which directly or indirectly may have a significant adverse effect on the existing condition of any tidal wetland, including but not limited to any form of draining, dredging, excavation and removal, either directly or indirectly, of soil, mud, sand, shells, gravel or other aggregate; any form of dumping, filling or depositing, either directly or indirectly, of any soil, stones, sand, gravel, mud, rubbish or fill of any kind; erection of any structures or construction of any roads, the driving of any pilings or placing of any other obstructions, whether or not changing the ebb and flow of the tide.
1. (1) Alteration shall have a commensurate meaning.
2. (2) Ordinary and necessary maintenance and repair of existing structures and areas, including but not limited to docks, piers, wharves, pilings, dolphins and paved areas, shall not constitute an alteration where such activity does not directly or indirectly have a significant adverse effect on the existing condition of such wetland.
3. (3) The depositing or removal of the natural products of the tidal wetlands in the process of recreational or commercial fishing, shellfishing, aquaculture, hunting or trapping shall not constitute an alteration where otherwise legally permitted.
(c) Adjacent area shall mean any lands immediately adjacent to a tidal wetland which the commissioner may reasonably deem necessary to preserve in order to effectuate the policies and provisions of the act.
1. (1) Unless the commissioner shall otherwise determine in a particular case, such lands shall extend for a distance of 300 feet in any direction landward from the landward boundary of the tidal wetland or to an elevation of 10 feet above mean sea level, whichever is closer to such boundary. In those areas in which bulkheads or revetments exist at the edge of such wetland, such 300 foot boundary shall be measured from the seaward edge of any such bulkhead or revetment.
2. (2) Such lands shall extend for such farther distance as the commissioner may determine in a particular case where he finds that one or more activities on the lands in question may directly or indirectly cause an alteration to the existing state of such tidal wetland.
3. (3) Such lands shall not include such extensive or numerous areas as the commissioner may determine after public hearing to be not necessary to preserve in order to effectuate the policies and provisions of the act.
4. (4) Pending the determination of the commissioner in a particular case, the most recent, as of the effective date of this Part, topographical maps published by the United States Geological Survey, Department of the Interior, having a scale of 1:24,000 shall be rebuttable presumptive evidence of such 10 foot elevation.

(g) Department shall mean the Department of Environmental Conservation.
(h) Hardship shall mean a condition unique and peculiar to the particular situation of the petitioner, which tends to impose a serious financial burden on the petitioner. Such condition shall not have been one created as a result of a voluntary act of the petitioner. The fact that an increase or decrease in the value of real property may result from the moratorium shall not be evidence of hardship.
