PIE is the result of an agreement between APA and FEMA, with ASFPM as partner, to produce a series of educational webinars on best practices in hazard mitigation planning.

Webinars revolve around 4 central themes:• Focus on all hazards.• Focus primarily on mitigation planning but

also its connections with recovery planning and preparedness.

• APA and ASFPM act as co-conveners of all planning exchange webinars.

• Planning exchange hosts will select topics and commit to moderate, present, and lead the planning exchange webinars.

“mangrove forests with widths of 6-30 km along the Gulf Coast of South

Florida attenuated storm surges from Hurricane

Wilma (Category 3) by reducing both the

amplitude and extent of overland flooding,

protecting the area behind the mangroves

from inundation. Numerical simulations

show that the inundation area by Wilma would

extend more than 70% further inland without the

mangrove zone”-Zhang et al 2012

• The Conservation Plan became Greenseams

• Primary Purpose: Flood Management

• Secondary: Multiple Benefits

Hoerig property

Greenseams® Program Beginnings

• Southeastern Wisconsin Regional Planning Commission GIS Analysis (2000)

• The Conservation Fund hired to be the “face” of the program (2001)

Greenseams® Program Characteristics

MMSD’s 2035 Vision(http://v3.mmsd.com/NewsDetails.aspx)

Integrated Watershed Management Goals:

Zero sanitary sewer overflows

Zero combined sewer overflows

Zero homes in the 100-year floodplain

Acquire an additional 10,000 acres of river buffers through Greenseams®

Use green infrastructure to capture the first 0.5 inch of rainfall

Harvest the first 0.25 gallons per square foot of area of rainfall

Energy Efficiency and Climate Mitigation & Adaptation Goals:

Meet 100% of MMSD's energy needs with renewable energy sources

Meet 80% of MMSD's energy needs with internal, renewable sources

Use the Greenseams® Program to provide for 30% sequestration of MMSD's carbon footprint

Reduce MMSD's carbon footprint by 90% from its 2005 baseline
