Submittal Materials and Guidelines
- Sensitive Areas Report
A digital copy, in addition to a single hard copy, of the Sensitive Areas Report must be submitted with the initial development application. Refer specifically to subsection 8:3.5.B.1 for report requirements.
- Sensitive Areas Plat Exhibit
If sensitive areas are present on a site, a Sensitive Areas Plat Exhibit, in accordance with Chapter 8:3.5, must be submitted as part of the Sensitive Areas Report.
- Mitigation Plan (as applicable)
If impact to any sensitive area is proposed that exceeds mitigation thresholds, a complete mitigation plan must be submitted at time of development application.

If sensitive areas are present on a site, AutoCAD/GIS Data must be submitted to include, at a minimum, all sensitive areas, buffers and impact boundaries, as well as any established Limits of Disturbance.
Request for Waiver
A waiver of the sensitive areas requirements may be approved if any of the conditions listed in chapter 8:3.5.A.6 are satisfied. A waiver request form must be submitted along with supporting documentation. Waiver may be requested for some or all of the sensitive areas listed in section 8:3.5. Requests must be made prior to filing a development application.
If waiver is approved, the completed approved waiver request must be submitted with the development application. If a waiver is fully or partially denied - or if the waiver request only applies to a portion of the sensitive areas listed in section 8:3.5 - then a Sensitive Areas Assessment and Report should also be submitted with the application.
