National Green Infrastructure Certification Program (NGICP)

• Initiated under the leadership of DC Water and

the Water Environment Federation (WEF), NGICP

• Sets national certification standards for GI

construction, inspection, and maintenance workers

• Designed to meet international best-practice

standards, NGICP advances the establishment

• f sustainable communities by:
• Promoting GI as an environmentally and

economically beneficial stormwater management option;

• Supporting the development of proficient

green workforces; and

• Establishing a career path for skilled GI

workers.

• 15 jurisdictions nationally have partnered

and are implementing NGICP locally

Scaling Green Infrastructure in Washington, DC

DOEE Voluntary GI Programs

• Public projects:

 Transportation right-of-way  Public buildings and parking lots

• Subsidies for Private Sector

 RiverSmart Homes  RiverSmart Roofs  RiverSmart Communities  RiverSmart Schools

• RiverSmart Rewards Discounts
• Challenges

 Maintenance  Siting GI in area not slated for redevelopment  Paying all or most of cost up front  Minimal incentive for partners to identify least-cost projects  SCALE

3

Regulations Key to MS4 Stormwater Solution

CSS MS4 MS4 MS4

• Municipal Separate Storm

Sewer System

 $7B+ GI build-out  $10 Mil/yr for GI  GI stormwater regulations

can achieve 10x the GI retrofits of voluntary programs

Optimizing Environmental Outcomes

CSS MS4 MS4 MS4

• GI located in MS4 is
• More beneficial for

waterbodies

• Less expensive
• Provides greater

environmental justice outcomes.

• GI size/capacity can

be optimized

Optimizing Environmental Outcomes

• Regulated site free to go off site

after achieving 50% of required retention on site.

Stormwater Retention Credit Trading

1.2” retention required = 10,000 gal. On-site minimum = 5,000 gal. Impervious surface = 14,000 sf

• Off-site volume is ongoing annual obligation.
• Two options to achieve Offv:
• In-lieu fee (ILF) payment to DOEE = $3.61/gallon/year.
• Privately tradable SRCs. 1 SRC/gallon/year.

Properties may receive discounts for retention up to the 1.2” storm and SRCs for retention up to the 1.7” storm.

Potential Financial Return

DOEE SRC Purchase Program

• Pay for performance option contract.
• 1 SRC = 1 gallon of installed GI retention capacity.
• DOEE pays for 3 years at a time.
• SRC generator has option to sell to DOEE per contract terms.
• Price floor provides certainty to private investors and SRC

generators.

• Engage private capital – e.g. $1.7M investment from Prudential.
• Incentivize GI retrofits in priority locations of MS4.
• Initial $11.5M investment to scale up if successful.

Benefits for District of SRC Purchase Program

• Risk of maintenance failure not born by DOEE.
• Risk of selecting site that will trigger regs not born by DOEE.
• Incentive to find least-cost opportunities on public & private land.
• Savings for ratepayers compared to DOEE building GI itself.
• SRCs as regulatory currency facilitates scaling up and down.
