Drainage Charges

It is necessary to maintain and repair existing storm drainage systems and to minimize natural stream erosion. This charge is passed on to the customers through their monthly water billings.

How much will you pay? The following storm water drainage fees have been set:

Residential Fee

Each house, duplex or triplex, regardless of size, will be charged an additional $3.79 per month for the Storm Water Utility Drainage System. The charge will be included on the customer’s water bill statement.

Commercial Fee

The fee for commercial and industrial properties is based on the amount of “impervious surface area”, where water is not readily absorbed, such as roofs, driveways and parking lots. The fee will be calculated on the following formula.

(square feet of impervious area / 1,895*) x $3.79 = monthly fee

*Note: The amount of 1,895 is the average square-footage of impervious area on a residential lot. That figure was used to determine the monthly proportionate fee for non-residential property.


If a business property has 10,000 square feet of impervious area, the company would pay $20.01 a month to the Storm Water Utility Drainage System.

10,000 / 1,895 = 5.28 x $3.79 = $20.01
