[Added 9-6-2005 by Ord. No. 38-2005]
A. 
In recognition of the fact that natural features contribute to the welfare of residents, the following regulations have been enacted to provide reasonable controls governing the restoration, conservation, disturbance, and management of existing conservation easements for all perennial and intermittent streams and all lakes and ponds in the municipality by establishing designated conservation easement zones. It shall be noted that this zone designation shall not be included in the requirement for area clear of easements for the bulk standards of the Zoning Ordinance.
B. 
In addition, the specific purposes and intent of this article are to:
(1) 
Reduce the amount of nutrients, sediment, organic matter, pesticides, and other harmful substances that reach watercourses, wetlands, subsurface, and surface water bodies by using scientifically proven processes, including filtration, deposition, absorption, adsorption, plant uptake, biodegradation, denitrification and by improving infiltration, encouraging sheet flow, and stabilizing concentrated flows.
(2) 
Improve and maintain the safety, reliability and adequacy of the water supply for domestic, agricultural, commercial, industrial and recreational uses along with sustaining diverse populations of aquatic flora and fauna.
(3) 
Regulate the land use, siting and engineering of all development to be consistent with the intent and objectives of this article, accepted conservation practices, and to work within the carrying capacity of existing natural resources.
(4) 
Assist in the implementation of pertinent state laws concerning erosion and sediment control practices.
(5) 
Conserve the natural features important to land and water resources (e.g., headwater areas, groundwater recharge zones, floodway, floodplain, springs, streams, wetlands, woodlands, prime wildlife habitats) and other features constituting high recreational value or containing amenities that exist on developed and undeveloped land.
(6) 
Work with floodplain, steep slope, and other ordinances that regulate environmentally sensitive areas to minimize hazards to life, property, and water features.
(7) 
Conserve natural, scenic, and recreation areas within and adjacent to wet areas for the community's benefit.
For the purposes of this article, the following definitions shall apply:
CLEAR-CUTTING
The large-scale indiscriminate removal of trees, shrubs and undergrowth with the intention of preparing real property for nonagricultural development purpose.
CONSERVATION EASEMENT ZONE
Areas surrounding municipally designated surface water bodies, including creeks, lakes and intermittent watercourses, that intercept surface water runoff, wastewater, subsurface flow, and/or deep groundwater flows from upland sources and function to remove or buffer the effects of associated nutrients, sediment, organic matter, pesticides, or other pollutants prior to entry into surface waters. This area may also provide wildlife habitat, control water temperature, attenuate flood flow, and provide opportunities for passive recreation. This buffer area may or may not contain trees and other native vegetation at the time of the article's enactment.
INTERMITTENT STREAM
A stream with a drainage area of 50 acres or greater.
MUNICIPAL ENGINEER
Professional and licensed engineer appointed by the Township Committee.
PASSIVE RECREATION
Activities that involve inactive or less energetic activities, such as walking, sitting or picnicking.
PERENNIAL STREAM
A stream that flows continuously throughout the year in most years.
SELECTIVE CUTTING
Not clear-cutting.
STREAM
A natural watercourse containing flowing water for at least part of the year.
A. 
The establishment of the conservation easement zone applies to the following areas which are identified on the municipal conservation easement map prepared by Remington & Vernick Engineers entitled "Conservation Easement Map," dated June 2005:[1]
(1) 
Lands adjacent to municipally designated streams within the municipality.
(2) 
Lands adjacent to municipally designated intermittent watercourses within the municipality.
(3) 
Lands at the margins of municipally designated lakes.

Editor's Note: The Conservation Easement Map is on file in the Township offices.
B. 
The measurement of the conservation easement zone shall extend a minimum of 75 feet from each defined edge of an identified watercourse or surface water body at bankfull flow or level or shall equal the extent of the one-hundred-year floodplain, whichever is greater. The District will consist of two distinct zones designated as:
(1) 
Zone One: This zone will begin at each edge of an identified waterway (which can include wetlands and intermittent watercourses) and occupy a margin of land with a minimum width of 25 feet measured horizontally on a line perpendicular to the edge of water at bankfull flow. Where steep slopes (in excess of 25%) are located within 25 feet of a municipally designated watercourse, Zone One shall extend the entire distance of this sloped area. If the distance of this sloped area is greater than 75 feet, there will be no requirement for the establishment of Zone Two. If the distance is less than 75 feet, the width of Zone Two will be adjusted so that the total buffer width (Zone One and Zone Two) will be 75 feet maximum.
(2) 
Zone Two: This zone will begin at the outer edge of Zone One and occupy a minimum width of 50 feet in addition to Zone One.
(a) 
Where the one-hundred-year floodplain extends greater than 75 feet from the waterway, Zone One shall remain a minimum of 25 feet wide and Zone Two shall extend from the outer edge of Zone One to the outer edge of the one-hundred-year floodplain.
(b) 
Width determination. The developer, applicant, or designated representative shall be responsible for the initial width determination of the conservation easement and identifying this area on any plan that is submitted to the municipality for subdivision, land development, or other improvements that require plan submissions or permits. This initial determination shall be subject to review and approval by the Municipal Engineer, governing body, or its appointed representative.
The following uses are permitted, either by right or after review and approval by the municipality, in the conservation easement zone. However, within any buffer, no construction, development, use, activity, or encroachment shall be permitted unless the activity is described in the Conservation Easement Management Plan, as outlined in § 225-81.9.
