Why did the residential fee change from a flat rate to a tiered rate?

The previous residential stormwater fee was simply a flat rate of $51/yr billed bi-monthly at $8.50/month.

The new structure determines the fee based on the amount of impervious surface area on the property. Impervious surface areas include driveways, buildings, construction sites, and farms. The fee structure is progressive meaning that a higher rate is charged for larger amounts of impervious surface area. This is the same principle as the progressive income tax.

The change to a tiered fee structure was motivated by considerations of engineering reality and social equity and fairness. It is an engineering fact that the impact and cost of runoff from impervious surfaces increases more than proportionately as the size of the area increases. For example, if a mansion is only four times as large as a cottage, the impact and cost of its runoff will be more than four times as great. Therefore, properties having more impervious surface due to large houses, driveways, tennis courts, sidewalks should pay more than less affluent properties. In summary, more affluent citizens (reflected in the size of their houses etc.) can afford and should bear a proportionately larger share of the cost.

The tiers are designed so that citizens with smaller impervious surface areas will not see an increase in the fee and, could possibly see a reduction. Those citizens with larger areas may see an increase in the fee.

Residential Stormwater Billing Tiers

If the impervious surface area is…

Between 1 and 2,000 sq ft then the fee will be $51 annually or $8.50 bi-monthly
Between 2,001 and 4,000 sq ft then the fee will be $54 annually or $9.00 bi-monthly
Between 4,001 and 6,000 sq ft then the fee will be $81 annually or $13.50 bi-monthly
More than 6,000 sq ft then the fee will be $108 annually or $18.00 bi-monthly.
