4. PHASE 1 - ESTABLISHING A SOLID FOUNDATION ESTABLISHMENT OF FUNDING SOURCE  2007 - Sapulpa established dedicated funding source to provide financing for long-range, comprehensive Flood & Stormwater Management Program to include: –Master Drainage Plan –Phase II NPDES Program –Ordinance update & creation of Stormwater Drainage Criteria –Construction of recommended projects –Other components  Success story significant for communities of all sizes

5. SEED MONEY  Sept. 2007 - Passed ordinance to establish stormwater fee for interim funding  $2.00/month/single-family dwelling  $10.00/month/non-single family structure  2008 - Seed money to fund impervious area fee study  Study goals - Establish fair, equitable & defensible fee - Provide foundation for projecting annual revenue IMPERVIOUS AREA STUDY ESTABLISHMENT OF FUNDING SOURCE OTHER COMPONENTS FUNDED BY SEED MONEY  Stormwater Management staff position  Phase I Master Drainage Study

6. ANNUAL BUDGETARY NEEDS IMPERVIOUS AREA STUDY - STEPS  Step 1 – Identify 25 typical single family residences to establish Equivalent Service Unit (ESU) as unit of measurement - 2,650 sq. ft.  Step 2 – Identify non-single family parcels  Step 3 – Using GIS, prepare polygons to measure number of ESUs for non-residential parcels - Total square footage of impervious area per parcel divided by 2,650 sq. ft. = total number ESUs/parcel  Step 4 – Convert GIS data to list with ownership data, parcel area, impervious area & ESU by parcel  Step 5 – Develop estimate of annual revenue to be generated IMPERVIOUS AREA STUDY

7. Polygon for measuring non-residential parcel size & impervious area SAPULPA IMPERVIOUS AREA STUDY

8. ANNUAL BUDGETARY NEEDS FUNDING COMPREHENSIVE STORMWATER PROGRAM  Determine annual budgetary needs for comprehensive stormwater program to include: - Phase II NPDES - Staff - Routine maintenance - Critical drainage projects - Street cleaning - Public education  Finance program with annual projected need of $730,000 ESTABLISHMENT OF ANNUAL BUDGET

9.  Project annual need - $730,000  Establish 1 ESU/month for single family parcels at $3.35/ESU/month  Establish greater of $2.75/ESU/month for non-single family parcels or $22/month equal to 8 ESUs not to exceed $1000/month  Example – 23,850 sq. ft. non-single family parcel = 9 ESUs @ $2.75/ESU or $24.75/month ESTABLISHMENT OF ANNUAL BUDGET PROCESS

10.  Using differential fees, projected revenue of $730,000  Automatic 5% annual increase for next 5 years or $35,000 to $45,000/yr.  End of 6 years – Projected revenue of $932,000/yr. ESTABLISHMENT OF ANNUAL REVENUE ANNUAL INCREMENTAL INCREASES UTILITY RATE STUDY
