Need a Permit?

Disclaimer: These maps are for informational purposes only. The Environmental Resources Mapper does not show all natural resources which are regulated by NYS DEC, and for which permits from NYS DEC are required. For example, Regulated Tidal Wetlands, and Wild, Scenic, and Recreational Rivers, are currently not included on the maps.

NYS Freshwater Wetlands Permit Required for any physical disturbance, within the boundary or within the 100 foot adjacent area, of a state protected freshwater wetland. Note: Freshwater wetlands within the Adirondack Park are not included on these maps; contact the Adirondack Park Agency for permit information.

NYS Protection of Waters Permit Required for:
- the disturbance of the bed or banks of a protected stream, which includes water bodies in the course of a stream of 10 acres or less, with a classification of AA, A or B, or with a classification of C with a standard of (T) or (TS).
- for the excavation or placing of fill in navigable waters of the state, below the mean high water level, including adjacent and contiguous marshes and wetlands, with a water classification and standard of C or D.

Rare Animals, Rare Plants, and Significant Natural Communities The Rare Plant and Rare Animal data layer does not show precise or exact locations of rare animals and plants. Rather, it shows those general areas where potential impacts to rare animals and rare plants may need to be addressed if a project or activity is proposed. The Significant Natural Communities data layers do show the actual locations of natural communities. If a proposed project or activity is located within a significant natural community, or within the vicinity of a significant natural community, potential impacts should be addressed. Whether a given action or project will impact a rare animal, a rare plant, or a significant natural community, and in what manner and to what degree, will require further consultation.
