Correcting our Stormwater Concerns
City of Troy adopted a Stormwater Management Utility that became
effective on January 1, 2008. The City of Troy was designated by
the Ohio EPA for inclusion into the State’s Stormwater NPDES
Phase II Program. This unfunded state program requires the City
to perform six (6) minimum controls for the protection of the
storm sewer system and the Great Miami River. The City has
teamed with the Miami Conservancy District for completion of two
(2) of the controls, leaving four (4) for the city to perform.
The costs for the stormwater Management Program and the
costs for the maintenance of the City’s storm drainage system
are funded by the Stormwater
Utility. City Council chose the most common method of developing
a Stormwater Utility, the Equivalent Residential User (ERU)
Method. The theory behind the ERU method is that the stormwater
Utility fees need to be proportionate to the cost of providing
stormwater service to all users. The Stormwater Utility fees are
based on the amount of impervious area on a property. Impervious
areas include but are not limited to areas that have been paved
and/or covered with buildings and materials that do not allow
natural infiltration. These include but are not limited to
concrete, asphalt, rooftop, blacktop, and compacted gravel.
The average square footage of impervious area for
residential units in Troy has been determined to be 3,000 square
feet. Therefore, one ERU is equal to 3,000 sq. ft.
Monthly rates per ERU have been established through 2017 and are
2013 - $4.55
2014 - $4.70
2015 - $4.80
2016 - $5.00
2017 - $5.25
Stormwater Management fees
will be placed on the city’s monthly utility bill. The bill also
identifies the number of ERUs that have been determined for your
If there are any adjustments
to the ERU calculations, the property owner may complete the ERU
Adjustment Request Form along with any pertinent information
required to reflect the requested adjustment. The Engineering
Division will review the request and notify the applicant of any
acceptable adjustments within 30 days of receipt of a complete
ERU Adjustment Form. The ERU Adjustment Request Form is included

recognizes that some non-residential property owners have
provided private stormwater management control that exceeds the
requirements of the City Design standards. Credits up to 20% may
be allowed if the applicant demonstrates significant stormwater
control that not only addresses on-site stormwater but
significantly improves regional stormwater quality and quantity.
Non-residential property owners interested in applying for ERU
credits may complete the Stormwater ERU Credit Application and
include all pertinent attachments. The Engineering Division will
review the application and notify the applicant within a
reasonable time of any applicable credits. The Stormwater ERU
Credit Application is included in this informational packet.
