        The permit includes requirements for the city to implement the Best Management Practices as outlined in our Integrated Stormwater Management Plan to the maximum extent practicable. ( As part of the permit, the City is required to prepare an annual report by November 1 of each year for the previous fiscal year (July 1 to June 30) to demonstrate compliance progress.
