The coming storm:Managing Roanoke’sStormwater Infrastructure Challenges
Solutions for Roanoke’s future
City of Roanoke – Engineering Division
Stormwater Utility Fee
• What is a stormwater utility fee?
• Why is it needed?
• How will I be affected?
City of Roanoke – Engineering Division
Stormwater Fee
• A stormwater fee (or utility) is similar to electric, telephone or cable TV charges. Fees are collected for specific services provided.
• Roanoke City Council authorized staff to develop a stormwater fee framework on July 20, 2009
• City Council will consider the program in late fall 2009
• Two public Hearings will be held – November-December
• Planned adoption in early 2010

Dedicated Special Revenue
Dedicated to Operation and Maintenance of public stormwater systems
• Real Property for capital improvements
• Engineering design
• Construction costs
• Monitoring of control devices
• Regulatory compliance and enforcement
• Pollution control and abatement
• Maintenance of stormwater facilities
• Program Administration
City of Roanoke – Engineering Division
Stormwater Fee
• All developed properties contribute runoff and
pollutants
• Fees are assessed in proportion to a property’s
contribution to runoff
• Runoff is proportional to Impervious Surface
• Municipal Separate Storm Sewer System (MS4) is
regulated for water quality
• Service area is the City of Roanoke
City of Roanoke – Engineering Division
Stormwater Fee - Background
• Roanoke has 13 major rivers and streams
• 9 of these are listed as impaired for water quality by the Department of Environmental Quality (DEQ)
• The amount of runoff is related to the amount of impervious surface, that is, roofs, driveways, parking areas
• Runoff carries pollutants to our rivers and streams
City of Roanoke – Engineering Division
Stormwater Fee
• Roanoke’s storm drain system is aging and has numerous improvement needs
• No major storm drain improvement projects have been undertaken in more than a generation
• Nearly 200 projects have been identified
• Current management approach may not allow Roanoke to meet minimum water quality standards
• There is an urgent and compelling need to upgrade Roanoke’s stormwater system immediately
City of Roanoke – Engineering Division
Stormwater Fee
• Current budget provides funding for only most urgent issues
• Proposed stormwater fee provides necessary financial resources to protect the city’s water quality now and in the future
• Water quality improvement is a community responsibility. We all contribute to the problem, and we all need to work together on the solution
City of Roanoke – Engineering Division
Roanoke’s Identified Stormwater Needs
• Capital Improvements
$60+ million, approximately 200 projects
• Maintenance and repair of aging infrastructure
• Stormwater quality regulatory requirements for MS4– VPDES Permit
– TMDL
– Impaired waterways

Proposed Stormwater Utility
• Cash funded program based on collected revenue
• Capacity to implement $3.0 million in new projects annually
• Build a maintenance reserve (5%)
• Offer incentives and /or credits for those willing to go beyond regulatory requirements or retrofit existing facilities
City of Roanoke – Engineering Division
Proposed Projects
• Projects have been identified for the first three years of the program– Neighborhood Projects
– Average project value $105,000
• An incremental approach to correcting our stormwater problems

Program Outline
• $3.00 per month per Equivalent Residential Unit (ERU) for residential properties
• Non-residential properties will be assessed on the measured impervious surface– $3.00 per month per 1,920 square feet of impervious
surface
• Estimated annual revenue $3.6 million
• 1/3 residential, 2/3 non-residential

Proposed Stormwater Utility
• All developed properties pay the fee
• Exemptions
– Follow the state code for required exemptions, generally public streets and City property
– Vacant unimproved properties
– “Self contained” drainage systems
