3 ABOUT SAPULPA, OKLAHOMA  Population of 21,000  Heart of Route 66  Official Main Street Community

4 PHASE 1 - ESTABLISHING A SOLID FOUNDATION ESTABLISHMENT OF FUNDING SOURCE  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 Passed ordinance to establish stormwater fee for interim funding  $2.00/month/single-family dwelling  $10.00/month/non-single family structure  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 $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

11 PHASE 2 - FUNDING MASTER DRAINAGE PLAN COMPREHENSIVE MASTER DRAINAGE PLAN  Fee funded Master Drainage Plan  City divided into 3 distinct regions  Each region funded over 24-mon. period  Total 6 drainage systems with 14 basins studied

12 MASTER DRAINAGE PLAN - METHODOLOGY  Existing drainage conditions studied using HEC-HMS, HEC-GeoRAS & HEC-RAS  Basin Problem Areas identified - Community education & involvement played vital role - About 100 comments received from public  Identification & evaluation of alternatives including: - Feasibility - Cost-effectiveness - Level of protection - Type of flooding  Recommended Plan with “best” solutions for dollars developed  Prioritization Criteria for ranking & implementation COMPREHENSIVE MASTER DRAINAGE PLAN

13 CITIZEN INPUT

14 FUNDING NATIONAL POLLUTANT DISCHARGEELIMINATION SYSTEM PHASE II  2003 – Federal NPDES Phase II mandate for small communities  Can create hardship  2009 – Fee funded fully equipped truck & staff PHASE 3 – FUNDING NPDES PHASE II

15 FUNDING OTHER PROGRAM COMPONENTS  Review & update of Floodplain Ordinance  Creation of Stormwater Drainage Criteria Manual to guide development  Priority MDP projects under review for funding  Example – Inlet Replacement Program prime candidate for incremental funding  Design currently underway  Local grant match  Maintenance program  Priority project construction  Stream restoration  Street sweeping  Public education PHASE 4 – FUNDING REGULATION PHASE 5 – CONSTRUCTIONFUTURE PHASES – MORE USES

16 FUNDING OTHER PROGRAM COMPONENTS  Sapulpa Master Drainage Plan - Downtown Basin Inlet Replacement  Total project cost - $2.3 million  Incremental costs - $100,000 to $200,000 per intersection FUTURE FUNDING

17 OPPORTUNITIES - JOINT PROJECTS & FUNDING  Partnering opportunity with street project s& funds  Street projects overlaid with drainage solutions on Webviewer  Utility fee combined with City’s dedicated $0.005 street sales tax  Drainage improvements phased with local street project to: - Reduce costs - Minimize neighborhood disruption - Construct needed public projects PARTNERING OPPORTUNITIES

18 OPPORTUNITIES - JOINT PROJECTS & FUNDING  CDBG funding opportunity  Utility fee combined with annual CDBG funds  Example – Area near Sapulpa Middle School with deep drainage ditches - Traffic hazard for buses - Drainage problems  Drainage & road improvements - including curb & gutter - funded jointly to: - Eliminate hazardous traffic conditions - Improve local drainage PARTNERING OPPORTUNITIES

19 SMALL COMMUNITY FUNDS AMBITIOUS PROGRAM  Dedicated funding source enabled development, growth & stability of comprehensive stormwater management program  Fee provided critical funding to: - Implement Phase II NPDES Program - Prepare Citywide Master Drainage Plan - Update Floodplain Ordinance - Create Drainage Criteria Manual  Additional benefits: - “Pay as you go” funding - Defensible, equitable & easy to implement thru utility billing - Not undue hardship on residents - Partnering opportunities with other funds & projects APPROACH BENEFITS

20 CONSTRUCTING SOLID FOUNDATION ONE BLOCK AT TIME  Used careful planning & forethought  Laid a dedicated & solid funding foundation  Began building comprehensive stormwater management program  Implemented stormwater management program one block at a time to: - Reduce flooding - Improve drainage & water quality - Regulate responsible growth & development - Maintain existing drainage system - Maximize limited resources  Demonstrated small communities can implement “NAI” using building block view to stormwater management CONCLUSION
