ABOUT SAPULPA, OKLAHOMA
Population of 21,000
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
ESTABLISHMENT OF FUNDING SOURCE
PHASE 1 - ESTABLISHING A SOLID FOUNDATION
Sept. 2007 - Passed
ordinance to establish
stormwater fee for interim
funding
$2.00/month/single-family
dwelling
$10.00/month/non-single
family structure
IMPERVIOUS AREA STUDY
2008 - Seed money to
fund impervious area fee
study
Study goals
- Establish fair, equitable &
defensible fee
- Provide foundation for
projecting annual revenue
OTHER COMPONENTS FUNDED BY SEED MONEY
Stormwater Management
staff position
Phase I Master Drainage
Study
ESTABLISHMENT OF FUNDING SOURCE
SEED MONEY
ANNUAL BUDGETARY NEEDS
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

ANNUAL BUDGETARY NEEDS
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
FUNDING COMPREHENSIVE STORMWATER PROGRAM
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
INCREASES
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.

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
COMPREHENSIVE MASTER DRAINAGE PLAN
PHASE 2 - FUNDING
MASTER DRAINAGE PLAN
Existing drainage
conditions studied using
HEC-HMS, HEC-GeoRAS
& HEC-RAS
Basin Problem Areas
Identification & evaluation
of alternatives including:
- Feasibility
- Cost-effectiveness
identified
- Level of protection
- Community education &
involvement played vital
role
- Type of flooding
- About 100 comments
received from public
Recommended Plan with
“best” solutions for
dollars developed
Prioritization Criteria for
ranking & implementation
COMPREHENSIVE MASTER DRAINAGE PLAN
MASTER DRAINAGE PLAN - METHODOLOGY
CITIZEN INPUT
2003 – Federal NPDES
Phase II mandate for small
communities
Can create hardship
2009 – Fee funded fully
equipped truck & staff
FUNDING NATIONAL POLLUTANT DISCHARGE
ELIMINATION SYSTEM PHASE II
PHASE 3 – FUNDING NPDES PHASE II
Review & update of
Floodplain Ordinance
Creation of Stormwater
Drainage Criteria
Manual to guide
development
PHASE 5 – CONSTRUCTION
Priority MDP projects under
review for funding
Example – Inlet Replacement
Program prime candidate for
incremental funding
Design currently underway
FUTURE PHASES – MORE USES
Local grant match
Maintenance program
Priority project construction
Stream restoration
Street sweeping

PHASE 4 – FUNDING REGULATION
Sapulpa Master
Drainage Plan Downtown Basin
Inlet Replacement
Total project cost $2.3 million
Incremental costs
- $100,000 to
$200,000 per
intersection
FUNDING OTHER PROGRAM COMPONENTS
FUTURE 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
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
OPPORTUNITIES - JOINT PROJECTS & FUNDING
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
SMALL COMMUNITY FUNDS AMBITIOUS PROGRAM
