Periodic inspection of stormwater management facilities is required throughout the development phase. It is the responsibility of the developer/builder to notify the municipal engineer well in advance of the completion of each identified phase and to arrange for the required inspection.
Work should not commence on a subsequent stage until the preceding stage has been inspected and approved. Any portion of the work which does not comply with the approved stormwater plan must be corrected by the permittee within a stipulated time. No work shall proceed on any subsequent phase of the stormwater management plan, the subdivision or land development, or building construction until the required corrections have been made.
If at any stage of the work the municipal engineer determines that the stormwater management controls or other requirements are not being installed as shown in the approved plans, the municipality may revoke existing permits until a revised plan is submitted and approved.
The following are key phases during which a municipality shall, at its discretion, perform routine inspections of the development site:
A. 
At the completion of preliminary site preparation, including stripping of vegetation, stockpiling of topsoil, and construction of temporary stormwater management and erosion control facilities.
B. 
At the completion of rough grading, but prior to placing topsoil, permanent drainage, or other site development improvements and ground covers.
C. 
During construction of the permanent stormwater facilities at such time as specified by the municipal engineer.
D. 
At the completion of permanent stormwater management facilities, including established ground covers and plantings.
E. 
At the completion of any final grading, vegetative control measures, or other site restoration work done in accordance with the approved plan and permit.
