Description:

Abstract: This is a graphical representation of the head of tide (hot) points for watercourses of New Jersey. This includes the tributaries of these watercourses as well.

Purpose: On 15 May, 1979, the Division of Purchase and Property, NJ Dept. of Treasury, issued an award to Coast Survey, Ltd. (CSL), on behalf of the Office of Environmental Analysis (OEA), Dept. of Environmental Protection (DEP). Under the terms of that obligation CSL was required to: a). Locate the 'Head of Tide' (HOT) on all watercourses and their tributaries within the 2452 square mile area of the State subject to investigations for tidal claims; b). Document tidal rise and fall on all such watercourses and their tributaries.

Supplemental Information: DEFINITIONS: 1). TIDAL WATERCOURSES: A tidal watercourse is distinguished by periodic rise and fall of the water surface resulting from the gravitational interaction of the earth, the moon, and the sun. 2). HEAD OF TIDE (HOT): The HOT is the point on a tidal watercourse at which measurement of the water surface vertical movement at MEAN HIGH WATER (MHW) becomes no longer practical. All points seaward of the HOT on a tidal watercourse are tidal. 3). UPPER WETLANDS BOUNDARY (UWB): The UWB is the line depicted on the New Jersey Wetland Photomaps prepared and filed in accordance with the Wetlands Act of 1970. CSL investigations started at the UWB and were carried out upstream of the UWB. 4). LIMIT LINE (LL): The LL is the line delineated on OEA Tidelands Basemaps, drawn only in cases where an area was not mapped under the 1970 Wetlands Act. CSL investigations started at the LL and were carried out upstream of the LL. Under the terms of the contract, CSL was not required to determine the HOT on: 1). Any watercourse within an area designated as "WETLANDS" on a promulgated State of New Jersey Wetlands Map. 2). Any watercourse seaward of the State LL. 3). Any watercourse less than 2.5 ft. in width. 4). Any watercourse on a Hackensack Meadowlands Map. 5). Any watercourse on a Newark-Elizabeth Meadowlands Map.
