Bigger & More Frequent Storms

Bigger Storms Mean More Precipitation

Overview of the Manomet Climate Change Adaptation Project

“Over most regions, precipitation is likely to be less frequent but more intense, and precipitation extremes are very likely to increase”

ErosionClimate Change is the Great Accelerator

Page 8: Great Marsh Coastal Resiliency Planning

Vulnerability = sensitivity + exposure + adaptive capacity

A resource is vulnerable if it is exposed and sensitiveto the effects of climate change and at the same time has only limited capacity to adapt.

Dept. of Interior Hurricane Sandy Resiliency Grants Program

“Community Risk Reduction through Comprehensive Community Resiliency Enhancement for the Great Marsh Ecosystem”

Project Area:• Salisbury, Newbury, Newburyport, Essex, Ipswich, & Rowley.

Resiliency Planning Objectives: • Assess overall community vulnerability as well provide focused assessments of

highly vulnerable high-priority community assets through a comprehensive and integrated approach.

• Identify operationally feasible, site-specific adaptation strategies that serve to reduce risk.

• Engage communities as we work together to lay a framework for future implementation of on-the-ground adaptation strategies.

Page 11: Great Marsh Coastal Resiliency Planning

1. Develop community climate vulnerability assessments2. Conduct comprehensive public outreach & engagement3. Publish an Adaptation Plan & Implementation Roadmap

Community Resiliency Planning

• Members were appointed to Community Task Forces in April 2015

• Task Forces convened in May & have met three times in regional groups

• Work has continued over past six months in person and off-line

• Committee work

• Sub-projects (MAST & COAST)

• Monthly conference calls

Page 19: Great Marsh Coastal Resiliency Planning

Identifying Current Vulnerabilities:Hazard Mitigation & other plans

• MVPC regional plan includes Rowley, Newbury, Newburyport & Salisbury

• Summarizes specific hazards and “targets” that are vulnerable

• FEMA Flood Risk report Essex County, MA – 2013

• Master plans

• Open space plans

• Natural Heritage Biomapreports

• The Salisbury and Plum Island Barrier Beaches are the #1 line of defense for our communities

• Unfortunately, developedbarrier beaches are much less resilient to impacts of climate change.

Community Vulnerability Assessment Introduction to Table Discussions

• Each table will have:

• List of assets • Maps to review• Facilitator• Note taker• Questions to spark discussion

Page 61: Great Marsh Coastal Resiliency Planning

Community Vulnerability DocumentsQuestions for Table Discussions

General• What climate-driven threats are you most concerned about ?• What’s the first thing that comes to mind when you think of climate threats? • What’s the best way to disseminate vulnerability information in your community?• How can we get our towns and general public to think more long term?

Specific• Are there additional vulnerable assets that we missed?• Of the high-priority assets we’ve identified, which assets are the most critical?• Looking 20 years into the future, how do you envision your community changing

and how will those changes exacerbate or mitigate climate-driven threats?
