→Inspection & Maintenance Terminology
*The property owner can specify in construction tenders or contracts to retain a certain percentage of the total value of the work done for a period of 12 months from the date of final completion.

**In such cases, construction contracts should specifically require that thorough inspection and testing of the BMPs be completed to the satisfaction of the property owner or their project manager, design consultants and construction contractors as a condition of Assumption, contract termination and release of the holdback amount.

===Routine Operation Inspections===
Routine Operation inspections should be the responsibility of the property owner or their contractors. At a minimum, Routine Operation inspections should occur annually, but twice annually (in spring and fall seasons) is preferable for vegetated BMPs. More frequent inspections may be warranted for highly visible BMPs, those receiving drainage from high traffic areas (vehicle or pedestrian), or those designed with larger than recommended impervious drainage area to pervious BMP footprint area ratio (i.e., I:P ratio). Feedback from inspections should be used to immediately address routine maintenance needs, schedule structural repairs or further investigations into potential problems with BMP function and to adjust the preset schedule of routine maintenance tasks to optimize the use of program resources.
Each LID BMP's I&M page will provide further guidance on Routine Operation inspection objectives and tasks, associated timing of said inspections and specific skills required by inspectors, along with key components to be inspected and what visual and testing indicators should be used, and recommended minimum frequencies.
Furthermore, blank template field data forms for recording inspection results are provided within each section as well to be downloaded and used for personal use.
===Verification Inspections===
Verification inspections should be the responsibility of the municipality or be a shared responsibility between the property owner (e.g., hires consultant to perform and document the inspections) and municipality (e.g., approves and tracks documentation). A Verification inspection could replace one Routine Operation inspection that the property owner is responsible for that year.
====Maintenance Verification====
*For permanent BMPs designed and installed to meet regulatory or municipal program requirements, inspections to verify compliance with ECA or maintenance agreement conditions and associated BMP specific inspection and maintenance plans (i.e., Maintenance Verification inspections) should occur on five (5) year intervals beginning after the date of assumption.
Maintenance Verification inspections should also be performed when property ownership changes to ensure the new owner is not assuming a BMP that has been neglected by the previous owner, and to help educate the owner about their inspection and maintenance and record keeping responsibilities. Inspection and testing to verify that functional performance remains acceptable (i.e., Performance Verification inspections)should at a minimum, occur on fifteen (15) year intervals beginning after the date of assumption.
====Performance Verification====
*More frequent Performance Verification inspections may be warranted for BMPs draining to highly sensitive receiving waters or habitat of species at risk. Testing of functional performance (e.g., surface infiltration rate testing, natural or simulated storm event testing, continuous monitoring) is done in addition to Maintenance Verification inspection indicators (i.e., visual indicators and sediment accumulation testing).
Feedback from Maintenance and Performance Verification inspections should be used to initiate compliance enforcement actions if warranted and schedule structural repairs or further investigations into observed problems with BMP function. Each LID BMP's I&M page will provide further guidance on Verification inspection objectives and tasks, timing of inspections and skills required by inspectors along with guidance to what key components should be inspected and what visual and testing indicators should be used along with available structural repair options.
Furthermore, blank template field data forms for recording inspection results are provided within each section as well to be downloaded and used for personal use.
