Stormwater Utility Level of Service Goal: Establish a utility that will fund a stormwater program for Fiscal Year 2013 Range being considered $1.7M up to $2.2M Basis This level will provide sufficient funding for all of the following: Personnel Regulatory compliance and required inspections Stormwater system maintenance program One or two capital projects or emergency projects per year Level of Service Ultimate Range of affordable options Existing CRS program enrollment and pursuit of grant opportunities Administration Capital Projects Operation & Maintenance 16
Stormwater Utility Funding Source Fees would be subject to change (pending Council approval) depending on the City s needs Impervious area is the equitable basis for a user fee SWAC prefers ERU methodology because it treats all residents equally Resulting revenues shall be used for stormwater program only 17
Anticipated Future Steps Interim and short-term implementation of CRS Roadmap Flood prone structure evaluation and ranking Grant application Stormwater management system evaluation CIP focused 18
Summary Build a strong foundation with a Living Master Plan Stormwater Master Plan Build upon the Master Plan to Implement Desired Goals Find a way to fund your program dedicated and recurring funding is the key Stormwater Utility Fund your program Floodplain Management 19
