West Orange City Zoning Code

Whenever an applicant seeks municipal approval of a development subject to this section, the applicant shall submit all the required components of the checklist for the site development stormwater plan at § 25-29.10c below as part of the submission of the application for approval.

The applicant shall demonstrate that the project meets the standards set forth in this section.

The applicant shall submit (specify number) copies of the materials listed in the checklist for site development stormwater plans in accordance with § 25-29.10c of this section.

Topographic base map. The reviewing engineer may require upstream tributary drainage system information as necessary. It is recommended that the topographic base map of the site be submitted which extends a minimum of 200 feet beyond the limits of the proposed development, at a scale of one inch equals 200 feet or greater, showing two-foot contour intervals. The map as appropriate may indicate the following: existing surface water drainage, shorelines, steep slopes, soils, erodible soils, perennial or intermittent streams that drain into or upstream of the Category One waters, wetlands and floodplains along with their appropriate buffer strips, marshlands and other wetlands, pervious or vegetative surfaces, existing man-made structures, roads, bearing and distances of property lines, and significant natural and man-made features not otherwise shown.

Environmental site analysis. A written and graphic description of the natural and man-made features of the site and its surroundings shall be submitted. This description shall include a discussion of soil conditions, slopes, wetlands, waterways and vegetation on the site. Particular attention should be given to unique, unusual, or environmentally sensitive features and to those that provide particular opportunities or constraints for development. The map shall indicate the following: existing surface water drainage, shorelines, steep slopes, soils, erodible soils, springs, seeps, intermittent or perennial streams, wetlands, and floodplains along with their appropriate buffer strips, marshlands and other wetlands, forests, and core forests, pervious or vegetative surfaces, existing man-made structures, roads, bearing and distances of property lines, and significant natural and man-made features not otherwise shown.

Project description and site plans. A map (or maps) at the scale of the topographical base map indicating the location of existing and proposed buildings, roads, parking areas, utilities, structural facilities for stormwater management and sediment control, and other permanent structures. The map(s) shall also clearly show areas where alterations will occur in the natural terrain and cover, including lawns and other landscaping, and seasonal high groundwater elevations. A written description of the site plan and justification for proposed changes in natural conditions shall also be provided.

Land use planning and source control plan. This plan shall provide a demonstration of how the goals and standards of §§ 25-29.3 through 25-29.5 are being met. The focus of this plan shall be to describe how the site is being developed to meet the objective of controlling groundwater recharge, stormwater quality and stormwater quantity problems at the source by land management and source controls whenever possible.

Stormwater management facilities map. The following information, illustrated on a map of the same scale as the topographic base map, shall be included:

Calculations.

Maintenance and repair plan. The design and planning of the stormwater management facility shall meet the maintenance requirements of § 25-29.12.

Waiver from submission requirements. The municipal official or board reviewing an application under this section may, in consultation with the municipality's review engineer, waive submission of any of the requirements in § 25-29.9c1 through 6 of this section when it can be demonstrated that the information requested is impossible to obtain or it would create a hardship on the applicant to obtain and its absence will not materially affect the review process.
