Provided no clearing of trees or vegetation, other than lawn, is required, pools and pool related appurtenances, such as walkways, patios, decks and fences, adjacent to a lawfully existing structure;

No more than 750 square feet of total lot coverage is permitted for any of the uses listed above, excluding the pool footprint but including pool related appurtenances.

Recreational uses, whether open to the public or restricted to private membership, such as parks, camps, picnic areas, golf courses (provided same are maintained in accordance with the most current integrated pest management practices and standards recommended by NJAES), sports or boating clubs, not to include enclosed structures, but permitting piers, docks, foot bridges, floats or pavilions usually found in developed outdoor recreational areas;

Outlets from sewage treatment plants and sewage pumping stations and the expansion of existing sewage treatment facilities;

Stormwater management best management practices (BMPs) in accordance with subsection 16-5.2; and

Where otherwise permitted by the applicable zoning district regulations, the construction of a single-family, detached dwelling on a pre-existing vacant lot, provided the dwelling and all associated development is located in an area outside of the floodway and the flood hazard area or special flood hazard area.

All new lots in major and minor subdivisions and new site plans shall be designed to provide sufficient areas outside of stream corridors to accommodate principal and accessory uses and structures regardless of the maximum building coverage, lot coverage or floor area ratio otherwise permitted by the subject zoning district. Lands remaining after subdivision that are predominately under agricultural production after the creation of lots through minor subdivision shall be exempt from the provisions of this section, provided that the agricultural lands are managed in accordance with subsection 16-16.6.

In evaluating all major and minor subdivisions, site plans, and variances the Planning Board or Zoning Board of Adjustment (hereinafter, either may be referred to as "Board") as the case may be, or the Floodplain Administrator in the case of municipal permit review, may allow an average stream corridor width of 100 feet from the Flood Hazard Area line or the top of bank of the stream channel, whichever the case may be, thus allowing reasonable flexibility to accommodate site planning when necessitated by the size and shape of the tract and physical conditions thereon. The stream corridor width may be reduced to a minimum of 50 feet provided there is an increase at a 2:1 ratio in the width elsewhere on site and all other relevant permits are obtained (e.g., flood hazard area, freshwater wetlands, etc.).
