1. In order to provide adequate protection of the quality of the lakes, ponds, rivers and streams of the park and the qualities of their shorelines, no person shall undertake any new land use or development or subdivision of land that involves any shoreline within the park, except in compliance, at a minimum, with the following restrictions. In addition, compliance with these restrictions shall be required by the agency in its review of any project under section eight hundred nine and, at a minimum, by any local government in the adoption and enforcement of a local land use program. All distances contained in these restrictions shall be measured horizontally. For the purpose of this section, any lot, parcel or site that adjoins a shoreline, includes a shoreline or, in whole or in part, is located at or within the minimum set back requirement as provided in subparagraph two of paragraph a of this subdivision, and any land use or development on such a lot, parcel or site, shall be deemed to involve that shoreline. a. In the case of the shorelines of all lakes and ponds and the shorelines of any river designated to be studied as a wild, scenic or recreational river in accordance with the environmental conservation law or any river or stream navigable by boat, including canoe, the following restrictions shall apply:
- (1) The minimum lot width measured along the shoreline for each one family residential structure shall be fifty feet in hamlet areas, one hundred feet in moderate intensity use areas, one hundred twenty-five feet in low intensity use areas, one hundred fifty feet in rural use areas, and two hundred feet in resource management areas; provided that the minimum lot width for a lot not adjoining or including shoreline which is deemed to involve shoreline for the purposes of this section may be measured lateral to the shoreline at any point on the lot. Nothing herein shall be deemed to preclude the application of appropriate shoreline restrictions to new uses other than one family residential structures subject to project review by the agency or to an approved local land use program.
- (2) The minimum setback of all principal buildings and accessory structures in excess of one hundred square feet, other than docks or boathouses, from the mean high-water mark shall be fifty feet in hamlet areas and moderate intensity use areas, seventy-five feet in low intensity and rural use areas, and one hundred feet in resource management areas.
- (3) The removal of vegetation, including trees, shall be permitted on shorefront lots provided the following standards are met:
- (a) Within thirty-five feet of the mean high-water mark not more than thirty percent of the trees in excess of six inches diameter at breast height existing at any time may be cut over any ten-year period.
- (b) Within six feet of the mean high-water mark no vegetation may be removed, except that up to a maximum of thirty percent of the shorefront may be cleared of vegetation on any individual lot. This provision shall be adhered to in addition to (a) above.
- (c) The above cutting standards shall not be deemed to prevent the removal of diseased vegetation or of rotten or damaged trees or of other vegetation that present safety or health hazards.
- (4) The following minimum shoreline frontages shall be required in all land use areas for deeded or contractual access to all such lakes, ponds, rivers or streams for five or more lots, parcels or sites or multiple family dwelling units not having separate and distinct ownership of shore frontage:
- (a) Where five to twenty lots or multiple family dwelling units are involved, a total of not less than one hundred feet.
- (b) Where more than twenty and not more than one hundred lots or multiple dwelling units are involved, a minimum of three feet for each additional lot or multiple dwelling unit in excess of twenty.
- (c) Where more than one hundred and not more than one hundred fifty lots or multiple dwelling units are involved, a minimum of two feet for each additional lot or multiple dwelling unit in excess of one hundred.
- (d) Where more than one hundred fifty lots or multiple dwelling units are involved, a minimum of one foot for each additional lot or multiple dwelling unit in excess of one hundred fifty. b. In the case of all lakes, ponds, rivers and streams, the minimum setback of any on-site sewage drainage field or seepage pit shall be one hundred feet from the mean high-water mark in all land use areas.
