Glossary
In the Waterfront Navigator glossary, we’ve compiled regulatory terms and definitions from agency documents, environmental terms you will come across when doing work in wetlands and in coastal areas, and abbreviations used by agencies or on this site. Definitions cite the sources, with links back to original documents or websites for further reference.
Natural habitat
A complex of natural, primarily native or indigenous vegetation, not currently subject to cultivation or artificial landscaping, a primary purpose of which is to provide habitat for wildlife, either terrestrial or aquatic. For purposes of this part, habitat has the same meaning as natural habitat. This definition excludes rights-of-way that are acquired with Federal transportation funds specifically for highway purposes. (Electronic Code of Federal Regulations, Title 23, Part 777, March 2016)

Navigable waters of the State (NY)
All lakes, rivers, streams and other bodies of water in the State that are navigable in fact or upon which vessels with a capacity of one or more persons can be operated notwithstanding interruptions to navigation by artificial structures, shallows, rapids or other obstructions, or by seasonal variations in capacity to support navigation. It does not include waters that are surrounded by land held in single private ownership at every point in their total area. (Rules and Regulations of the State of New York, Title 6.

Groundwater is the primary source of water for stream flow. Runoff from rainfall is a supplemental source of water for stream flow. (US Army Corps of Engineers, 2012 Nationwide Permits, Conditions, and Definitions)
Perimeter

A public hearing may be held to acquire information and give the public the opportunity to present views and opinions. The Corps may hold a hearing or participate in joint public hearings with other Federal or state agencies. The district engineer may specify in the public notice that a hearing will be held. In addition, any person may request in writing during the comment period that a hearing be held. Specific reasons must be given as to the need for a hearing. The district engineer may attempt to resolve the issue informally or he may set the date for a public hearing. Hearings are held at times and places that are convenient for the interested public. Very few applications involve a public hearing. (US Army Corps of Engineers New York District, Regulatory Program Applicant Information Guide, 2014)
Public interest review
This term refers to the evaluation of a proposed activity to determine probable impacts. Expected benefits are balanced against reasonably foreseeable detriments. All relevant factors are weighed. Corps policy is to provide applicants with a timely and carefully weighed decision that reflects the public interest. The public interest review requires the careful weighing of all public interest factors relevant to each particular permit application. Thus, one specific factor (e.g., fish and wildlife values or economics) cannot by itself force a specific decision, but rather the decision represents the net effect of balancing all public interest factors, many of which are frequently in conflict. The public interest review is used to evaluate applications under all authorities administered by the Corps. (US Army Corps of Engineers New York District, Regulatory Program Applicant Information Guide, 2014)
Public notice
