Commentary:
This Council Order will set both the stormwater service fee schedule and the schedule for credit
standards under the stormwater ordinance.
On May 30, 2012, the City Council passed a stormwater utility ordinance establishing a dedicated
funding source for the City's stormwater program. Among other provisions, the ordinance
stipulates that the Council will establish a fee schedule which sets forth the fees paid by
properties for the management of storm water. Additionally, the fee structure contains a credit
schedule by which service charges may be reduced in return for stormwater mitigation efforts.

(TITLE.) ORDER, Setting the Stormwater Service Fee Schedule and Credit Schedule for the
Bangor Stormwater utility
WHEREAS, on May 30, 2012, the Bangor City Council passed a stormwater ordinance to
establish a structure for a dedicated fee or service charge to support the City of Bangor
stormwater program;
WHEREAS, the basic principle behind the stormwater fee is that properties are charged for their
Impact on the City's stormwater system, including its streams, drainage pipes, and treatment
systems;
WHEREAS, the stormwater service fee provides a stable, equitable source of revenue for the
stormwater program based on the cost of stormwater management practices to be paid for by
the City that allocates the costs of these stormwater services across property owners in the City
of Bangor;
WHEREAS, the impact of a property on the stormwater system, and therefore the fee, is based
on the amount of impervious surface area on the property; and
WHEREAS, the stormwater ordinance provides for adjustments to the stormwater service fee
for properties that reduce demand on the stormwater system by using appropriate stormwater
management practices;
By the City Couiwl of the City of Bangor.
ORDERED,
THAT the stormwater service fee provided for in Chapter 268, Section 18 of the Code of the
City of Bangor is hereby established as follows:
Basic rate structure. The fee for the first 3000 square feet of impervious cover on a parcel
of land is a flat fee of $22 per year. Each additional 1000 square feet of impervious cover adds
$11 per year to the basic fee.
Calculating square footage. Aerial photography and precise photogrammetric mapping
were used to measure the amount of impervious surface on each property. For billing
purposes, the measured amount of impervious cover on a parcel is rounded to the nearest
1000 square feet. For example, a parcel with 3499 feet of impervious cover is rounded to 3000
square feet, and so pays $22 per year.
BE IT FURTHER ORDERED

attached to this Order.
