'''Final Certification'''
'''Final Certification'''
Final inspection requirements are in-place to ensure that a final site-wide inspection is performed and that mitigation can occur before the contractor is relieved of responsibility. Final certifications are performed by knowledgeable personnel, such as the design engineer, who are qualified to ensure that LID features are operating as intended. This stage is critically important, as it is the last opportunity for issues to be resolved before the property owner assumes responsibility of the practice. Four (4) levels of inspection exist for final inspections of LID infiltration and filtration practices.<ref>https://cvc.ca/wp-content/uploads//2021/07/2016-04-21-web-version-CVCbioretentionCertificationProtocols.pdf</ref> The level of inspection, or combination of tests, that is selected is dependent on the goals of the assessment and feasibility of each inspection.
