Video on how the Maintenance Guidance materials (Maintenance Plan, Field Manuals, and Maintenance Logs and Inspection Records) work together.

The Maintenance Plan incorporates the rule requirements for maintenance plan contents and additional items addressed in the NJ Stormwater BMP Manual chapters: Structural Stormwater Management Measures and Chapter 8 – Maintenance and Retrofit of Stormwater Management Measures, in the form of a template to assist design engineers with the preparation of their maintenance plans. Please download the Stormwater Management Measures templateto assist design engineers with the preparation of their maintenance plans.

Each field manual includes templates for basic design information, checklists, visual aids, reference documents, and maintenance records. This provides a systematic method to assist maintenance crews in performing field work and retaining records. Each Field Manual was developed with the consideration of essential maintenance requirements for each type of stormwater measure addressed in the corresponding Structural Stormwater Management Measures subchapters within the NJ Stormwater Best Management Practices Manual.

Some maintenance activities may require State permits depending on specific circumstances, such as, but not limited to, design, access, disposal methods, and methods of repair. Below is a list of possible activities including possible permits and associated program areas that may be needed during the maintenance of a stormwater management measure. The list below does not cover all activities which require approval, and may not cover all Department permits required for an activity, but it provides guidance on some of the more common activities.

The National Climatic Data Center provides current and historical precipitation information, which can assist maintenance crews with assessments.
