Township of Greenwich, NJ Article V Submission Requirements

§ 594-14 General.

This section provides the minimum submission requirements for a Stormwater Management Plan. The applicant shall refer to the above-mentioned NJDEP manuals regarding BMPs and facilities maintenance as a guide in preparing the scope of the project report and maps discussed below.

§ 594-15 Project report.

The applicant shall prepare a report which includes the following:

A. A written description of existing conditions on the project site. This description shall include a description of natural and man-made features of the site with emphasis on soil conditions, slopes, wetlands, water bodies and vegetation. Particular attention shall be paid to unique or environmentally sensitive features as they relate to stormwater runoff quantity and pollutant loads.

B. A written description of the proposed project with particular emphasis on aspects of the project which relate to stormwater runoff quantity and pollutant loads, and changes to the stormwater drainage characteristics of the site as compared to existing conditions.

C. Data and calculations regarding existing and proposed stormwater quantity and pollutant loads; and design and analysis of stormwater conveyance facilities, including but not limited to the following:

(1) For infiltration facilities proposed to meet the no-net-increase objectives of this chapter, the results of a subsurface investigation and soil tests demonstrating the suitability of the area's soils and groundwater infiltration and treatment of runoff shall be provided.

(2) A nonpoint source pollutant loading analysis shall be prepared and submitted, demonstrating that the nonpoint source pollutant and sediment loadings resulting from the proposed land development or construction project do not exceed the standards set forth in this chapter.

D. A written demonstration regarding how the proposed project satisfies the goal of no net increase as provided in this chapter.

E. A detailed maintenance and monitoring plan. This plan shall, at a minimum, demonstrate the methods and frequency of maintenance activities and identify the entity responsible for maintenance.

§ 594-16 Maps.

The applicant shall prepare the following maps in connection with the project report:

A. A topographic map showing existing conditions at the site at a scale of one inch equals 200 feet or greater showing two-foot contours and extending a minimum of 200 feet beyond the project site boundaries. The existing conditions map shall delineate floodplain areas and environmentally sensitive features (e.g., slopes exceeding 15%, wetlands areas, endangered species habitats, aquifer recharge areas, etc.).

B. A topographic map showing proposed conditions at the site with the same scale and characteristics as the existing conditions map.

C. A stormwater facilities map with the same scale and characteristics as the existing conditions map illustrating all stormwater management facilities.

§ 594-17 Waiver of submission requirements.

An application under this chapter may be exempt from all or a portion of these submission requirements where it can be demonstrated that the information requested is impossible to obtain or it would create a hardship on the applicant.
