How should a stormwater management plan be updated?

A stormwater management plan should be updated periodically or whenever significant changes occur at the facility because this approach ensures that the plan remains relevant and effective in addressing current conditions. Facilities can undergo various modifications, such as changes in operations, construction activities, or alterations in the surrounding environment that can impact stormwater runoff and potential pollutants. Updating the plan in response to these changes helps ensure compliance with regulatory requirements and improves the facility's ability to manage stormwater effectively.

Regular reviews can also help identify any areas where the plan may need to be enhanced or adjusted based on new regulations, technology, or best management practices. This adaptive management strategy is crucial for maintaining environmental protection and ensuring that the facility minimizes its impact on stormwater quality and quantity.
