(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 ywe do things around here?)

5. Will you hear anything today that helps overcome those challenges?challenges?

Please take a moment to answer any/all of the questions on the forms provided and we’ll collect them after the the forms provided and we ll collect them after the presentation

Addressing Challenges Head On:

1. Establish a Forum to resolve policy 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,

Wh t i G I f t t ?What is Green Infrastructure?

Adaptable term used to describe an array of Adaptable term used to describe an array of products, technologies, and practices that use natural systems – or engineered systems, that 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 Infrastructureast uctu e

18Why Green Infrastructure ?

Your Water Quality Suffers8 % f ll ti t th ti i t

W y G ee ast uctu e ?

• 80% of pollution to the aquatic environment comes from land-based sources, such as runoff pollutionrunoff pollution

• New York has identified nonpoint sources as th i f t lit bl the primary cause of water quality problems in 91% of its priority waterbodies

• Once a watershed’s impervious cover exceeds 20%, water quality begins to suffer

S i f fi i h f ff M i f d h f • Static storage of first inch of runoff• Maximum loading ratio of 10:1

(impervious area to infiltration area); 5:1 is preferred

• Maximum surface grade change of 1-2 feet; steeper sloped areas may warrant a change in bottom elevation (via berms or other)U ” f th i filt ti b d • Geotextile liner separating rock

from soil (non-woven or woven… or sand?)

• Impervious liner where needed

• Upper 3” of the infiltration bed subgrade should be scarified prior to bed installation (if necessary)

• Total facility depth should between i h (f t id ti )(proximity to utilities, buildings,

etc)• Observation well and cleanouts • Perforated distribution pipe and/or

24-31 inches (frost consideration)• Protect existing utilities• Setbacks:• 10ft to buildings with basementsp p /

underdrain• Dewater within 72 hours• Level bed/trench bottom

g• 3ft to buildings without basements• 3ft from utility structures, vents,

poles, etc• Overflows for larger storm volumesOverflows for larger storm volumes
