The frequency of Construction inspections may be determined by the municipal stormwater infrastructure program policy or may be general program targets (e.g., weekly, after large storm events, as triggered by construction milestones and hand-off points between different contractors). At a minimum, inspections should occur just prior to the onset of BMP construction to ensure compliance with erosion and sediment control plans and after any large storm event (e.g., 15 mm rainfall depth or greater) during the BMP construction period. The figure to the right describes a recommended process for conducting construction and assumption inspections.

Feedback from Construction inspections should be used to correct any issues associated with BMP installation or Erosion Sediment Controls (ESCs) and to identify when changes to the installation procedures, ESCs or BMP design are needed due to site circumstances or complications encountered. In cases where the project proponent or property owner uses a formal bidding process to select a construction contractor, opportunities exist to include special provisions in tender documents or contracts that will help ensure that LID BMPs receive adequate inspection and maintenance during construction.
