1. Have you ever heard of Green Infrastructure (GI)?
2.
2 If so, what d
h t does it mean t you?
to ?
(stormwater management? energy savings? other?)
3. What are your biggest fears about
implementing GI?
4. What are your biggest hurdles to implementing GI (regulatory?
management? workers/staff on the ground? financial? that's not the way
g / ff g f y
we do things around here?)
5. Will you hear anything today that helps overcome those
challenges?
Please take a moment to answer any/all of the questions on
the forms provided and we’ll collect them after the

Addressing Challenges Head On:
dd h ll d
1.
1 Establish a Forum to resolve policy issues
issues,
2. Demonstrate key technologies early in the program,
3. Incentivize GI (e.g. Green Improvement Fund),
4. Add Green Infrastructure onto existing capital projects,
and
5.
5 Have a world class website.

What is Green I f t t ?
Wh t i G Infrastructure?
Adaptable term used to describe an array of
products, technologies, and practices that use
natural systems – or engineered systems, that
mimic natural processes to enhance overall
environmental quality and provide utility services
What do WE use it for?
Primarily, to capture rainwater during storm events
to reduce the need for more “gray” infrastructure

Why Green Infrastructure ?
ast uctu e 18
Your Water Quality Suffers
• 8 % of pollution t th aquatic environment
80% f ll ti to the ti i t
comes from land-based sources, such as
runoff pollution
• New York has identified nonpoint sources as
the i
th primary cause of water quality problems
f t lit bl
in 91% of its priority waterbodies
• Once a watershed’s impervious cover
exceeds 20%, water quality begins to suffer
