Challenges
• GI BMPs are by nature scattered across a
jurisdiction
• Local governments have the main
regulatory burden of addressing
stormwater issues like CSOs, but …
• Many of the most ideal sites for GI will be
on PRIVATE property
![Page 9: Innovative Financial Strategies for Stormwater Green ... and... · 29/05/2014 · Green Infrastructure (GI) “An array of products, technologies and practices that use natural systems](https://reader033.vdocument.in/reader033/viewer/2022052102/603c211bf98af9213810afda/html5/thumbnails/9.jpg)
Private Investment Necessary
• U.S. communities are facing a total of
$106 billion in needed stormwater
management and combined sewer
correction upgrades or improvements Source: American Rivers et al. 2012. Banking on Green: A Look at How Green
Infrastructure Can Save Municipalities Money and Provide Economic Benefits

Evolving Stormwater Finance
1. General government uses tax revenue to pay what it can to manage stormwater on public land
2. Regulations drive private property projects
3. Off-set fee programs/impact fees
4. Governments establish enterprises and stormwater fees to generate revenue
5. Rebates/cost share programs
6. Fees increase to level where crediting fees for on-site improvements becomes viable incentive
7. Loans
8. Tax incentives
9. Trading
10. Property Assessment Backed (e.g. PACE like)

Stormwater Credits
![Page 13: Innovative Financial Strategies for Stormwater Green ... and... · 29/05/2014 · Green Infrastructure (GI) “An array of products, technologies and practices that use natural systems](https://reader033.vdocument.in/reader033/viewer/2022052102/603c211bf98af9213810afda/html5/thumbnails/13.jpg)
What is the first thing you think of
when you hear stormwater fee?
1. An unfair disguised tax
2. An essential method of allocating
stormwater costs
3. A device for encouraging private
investment
4. Time to look for a new job

Credit/Discount on Stormwater
Utility Fees • A reduction in (monthly) fee due to installation of
BMPs
BENEFITS:
• Allow rate payers to control and reduce their service fee
• Improve legality of a stormwater utility fee
• Encourage private property owner participation in both water quality and flood relief improvements
• Reduce public expenditures on the stormwater management program

Credit Programs: Subscription
Rates
• Question: Of the total number of
stormwater utility accounts, how many
receive credits?
• Conservative interpretation of the
results: 0.03% - 0.37% of the accounts
take advantage of credit programs

Philadelphia - Stormwater Management
Incentives Program (SMIP) Grant
Water Commissioner Howard Neukrug:
“By working with customers who can
manage stormwater from many acres of
hard surfaces – and ideally public runoff
from streets – we can transform pockets of
our combined sewer areas into green acres
in a cost effective way. This is the best
example of a public/private partnership.”

Stormwater Retention Credit (SRC)
Trading Program
Through the Stormwater Retention Credit (SRC) trading program, projects that trigger stormwater regulations may buy and use SRCs or pay an in-lieu fee to meet their requirements for retaining stormwater. Other District properties generate SRCs by exceeding their own regulatory requirements or voluntarily installing retention practices such as green roofs and rain gardens. The SRC market provides flexible and cost-effective compliance options for the regulated community as well as financial incentives to voluntarily increase stormwater retention in the District.
