Certification & the GPC
Vision
• Create a new rating system that
will transform the parking
industry
• Address a critical void in the
green building marketplace
Operating Philosophy
• Collaborative
• Volunteer driven
• Open source
• Ready for challenge, revision,
adaptation, growth,
transformation
Current Framework
• Organized for both new and existing structured
facilities
– LEED/GG may apply to new
– Addressing existing critical to success
• Meaningful, with enough “teeth”, yet
achievable with commitment
– “Excessive burden” of LEED
Overarching strategies
Increase:
1. Committed & educated leadership
2. Transportation alternatives
3. Energy efficiency
4. Use of renewable energy
5. Support for rating systems
6. Community & vitality
Decrease:
1. Carbon emissions & pollution
2. Waste generation
3. Harmful chemical use
4. Potable water use
5. Cost

Today’s Opportunity
• Application of certification strategies to
Philadelphia’s parking industry – both surface
and structured assets
• Generate business opportunities, decrease
operational costs, and do the right thing
• Lead the market in innovation and creativity
Unique Philly Opportunity
• Parking is part of the solution, rather than the problem
• Focus on voluntary efforts to improve facilities
• Support &
• Collaboration opportunity versus adversarial relationship
• Recasting of relationship as private AND public parking
facilities

Drawing Private Capital to Green Infrastructure October 2012
Presented by:
Alisa Valderrama
Natural Resources Defense Council
Overview
• Deploying green infrastructure at a citywide or regional scale can help meet
Clean Water Act goals for stormwater (MS4) and sewage overflows (CSOs).
• Major, long-term investment is required to green the existing built environment
in our cities.
• Need to take advantage of both public and private funding sources.
• Cities can leverage private investment through policies that:
(i) Establish design/performance standards for redevelopment projects;
(ii) Drive private property owners to retrofit existing developed parcels; and
(iii) Create or enhance opportunities for private capital to underwrite up-front
costs of retrofits.
• With appropriate public policy and financial toolkits, private capital investment
can enable and accelerate green infrastructure retrofits.
• Philadelphia provides an excellent test case!

Philadelphia’s Green City Clean Waters Plan
• Relies on green infrastructure for a majority of the required reductions in sewage
overflows
• City can claim credit for “greened acres” on private property:
• Greened acres through redevelopment standards
• Greened acres through voluntary retrofits on existing developments
• Stormwater fees and credits incentivize private property owners to retrofit
existing development
Philadelphia’s parcel-based stormwater rate
structure
• Previous stormwater fee based on water usage (measured by water meter)
• New fee based on: impervious surface area + gross area + min. parcel charge:
For fiscal year 2014 (proposed):
Impervious area= $4.50 per 500 sf
Gross area rate= $0.56 per 500 sf
17
The new fee structure may also improve the
“financeability” of green infrastructure retrofits:
• Substantial discount on fee available for owners who manage first inch of
stormwater on their parcel.
• Parcel owners need to re-apply for the credit every four years.
• Over time, retrofits will pay for themselves through avoided stormwater fees.
Example: Under Philadelphia’s current rate and fee, for example, project costs
should fall below $36,000 per acre ($0.82 per square foot) if the project is to pay
back within 10 years.
Limited data to generalize about retrofit costs
Value of credit will go up over time as stormwater rates increase
18
Many parcel owners lack the cash to pay the upfront
costs of retrofits and will likely seek financing
• Traditional financing mechanisms are likely unavailable because of:
Existing leverage on assets and lack of collateral
No track record of repayment for such loans
• As a result, many property owners are unable to respond to the incentives created
by the credit and fee structure

NatLab: Innovative Financing for Stormwater Retrofits s
20
The Natural Infrastructure Financing
Lab (NatLab) is a partnership
between the NRDC, EKO Asset
Management, and The Nature
Conservancy
Sponsorship
Goal
Pilot Project
Develop innovative strategies for
financing conservation and green
infrastructure
Focus on deployment of green
infrastructure (“GI”) solutions for
storm-water management in
Philadelphia
Looking Ahead…
Large scale potential for private investment in green infrastructure retrofits
• Nationwide:
o About 1,000 communities already have impervious area-based stormwater fees;*
many of those offer credits for property retrofits that reduce runoff
o 770 CSO communities, over 7,000 MS4 communities
• Philadelphia is an incubator for green infrastructure financing ideas
o Philadelphia has one of the most enticing stormwater fee reductions available
o NatLab (Natural Infrastructure Financing Laboratory)
NRDC, TNC, & EKO Asset Management Partners
Working with the City to develop and implement financing strategies

• Something for which we advocate
How we think about sustainability
Sustainability is about managing
complexity in ways that increase value
and reduce risk.
Why it matters so much to us…
It is About the Soil …
