How did you come up with the cost of the stormwater assessment?

A list of known problems, scheduled improvements, and projected projects to comply with regulatory requirements was used as a basis for preparation of a forecast of stormwater program expenses. A five-year budget projection, including administrative and operation & maintenance costs, was also developed to establish funding needs. These overall stormwater system costs were distributed over the number of ETUs to come up with an equitable and fair assessment.
