BUILDING COASTAL RESILIENCE

THROUGH INNOVATIVE TOOL DEVELOPMENT

MISSION OF CAPE COD

COMMISSION

…TO PROTECT THE UNIQUE VALUES + QUALITY OF

LIFE ON CAPE COD BY COORDINATING A

BALANCED RELATIONSHIP BETWEEN

ENVIRONMENTAL PROTECTION + ECONOMIC

PROGRESS.

NOAA COASTAL RESILIENCY GRANTN AT I O N A L AWA R D S

Competitive grants for projects that

advance coastal resilience through:

• Land/ocean use planning• Disaster preparedness projects

• Environmental restoration • Hazard mitigation planning

• Other regional/state/community planning efforts

STEP 4: Take action.

STEP 3: Evaluate risks & costs.

STEP 2: Investigate options.

STEP 1: Identify the vulnerabilities.

STEPS TO RESILIENCE:

DEVELOP DECISION SUPPORT TOOL

Investigate options.

• Provide access to data

on natural hazards

• Interpret climate,

weather and coastal

geology data

• Review and comment

of strategies database

• Advise the team on

how to apply strategies

across the Cape

• Ensure the

implementation of

appropriate strategies

across the region
