URBAN COAST INSTITUTE COASTAL RESILIENCY INDICATOR PROJECT Urban Coast Institute Monmouth University September 10, 2008
PRESENTATION OVERVIEW Definition of coastal resilience Project goals and approach
WHAT IS RESILIENCE? The ability of a natural/human system to maintain its structure and function in the event of a hazard/disturbance The ability of a system to re-organize following disturbance-driven change (Louis Lebel, 2001)
COASTAL HAZARDS/DISTURBANCES Episodic Events: e.g., resilience to hurricanes, tropical storms, etc. Chronic Conditions: e.g. sea level rise, erosion, etc.
AN EXAMPLE OF NATURAL RESILIENCE(TO BEACH EROSION) Loss of summer berm to offshore zone during winter storms Restoration by wave-induced transport during summer
SOCIAL SYSTEM RESILIENCE Communities are also stressed by natural hazards and chronic disturbances; communities exacerbate natural hazards with development Communities can learn and adapt from past experiences
AN EXAMPLE OF A RESILIENT COMMUNITY Preserves natural areas Guides development away from high hazard areas Adopts hazard code standards Organizes emergency response networks
CHARACTERISTICS OF RESILIENCE Resistance to a hazard or disturbance e.g., build a levee to resist floods (artificial) e.g., add dune grass/fencing (natural) Restoring force (feedback) e.g., coastal processes (natural) hazard insurance, beach replenishment, emergency response, etc. (social)
CHARACTERISTICS OF RESILIENCE Adaptability- learning from previous experience e.g., stricter building codes, managed retreat, etc. Collaboration e.g., agency and stakeholder participation in hazard mitigation planning Redundancy and Diversity e.g., multiple safeguards (not relying on only one)
VULNERABILITY A characteristic that creates the potential for harm A function of both EXPOSURE and SENSITIVITY
FACTORS CONTRIBUTING TO VULNERABILITY (Cutter, 2000, 2003, 2006, 2008) • Physical vulnerability-location • Density of built environment • Infrastructure • Economic health • Demographics
Project Goals: To identify core indicators of coastal resiliency and vulnerability To design a coastal resilient community framework 9/19/2014
Basic Approach: Establish hazard resilience baseline following Cutter (2008) “A Framework for Measuring Coastal Hazard Resilience in New Jersey Communities” Sets approach for establishing a hazard resilience measurement baselinethat can serve as a benchmark or indicatorfor monitoring progress
Social Vulnerability • Social VulnerabilityIndex quantifies differences in social vulnerability among places and census block groups
Social Vulnerability Social Vulnerability Index Variables:-ethnicity-age-number of people per household-income-education
Built Environment and Infrastructure • Variables:-number of pre-1960 houses-housing density-commercial establishments-lifelines (e.g. schools, hospitals)-transportation -wastewater treatment facilities-historic landmarks, churches, etc.
Natural Systems and Exposure • Variables • FEMA 100-yr and 500-yr flood zone delineations • Dune size • Erosion rates • Wetland areas • Natural habitats • Storm surge inundation areas
Hazards Mitigation and Planningfor Resilience • Community variable checklist & score: • Emergency response plans • Building standards, codes, enforcement • Hazard mitigation plans • Zoning • Coastal setbacks • Dune management • NFIP • TDR
Constructing Community Resilience Baseline • Social Vulnerability + Built Environment Vulnerability + Hazard Exposure – Resilience = Community Resilience
Example: Monmouth Beach Social Vulnerability (low) Built Environment Vulnerability (high) Hazard Exposure (high) Resilience (measures have been taken to reduce risk) Community Resilience (additional measures are necessary to increase resiliency)
FEMA FLOOD ZONE MAP FOR MONMOUTH BEACH • Old (1992) 100-year flood zone boundary: Yellow Line • New 100-year flood zone boundary: Blue Line
Example: Monmouth Beach Source: NJ Beach Profile Network Richard Stockton College
Example: Monmouth Beach Source: NJ Beach Profile Network Richard Stockton College
Example: Monmouth Beach Source: NJ Beach Profile Network Richard Stockton College
Example: Monmouth Beach • Hazards Exposure variables • Area of FEMA 100-yr flood zone delineations • Number of houses in 100-yr flood zone • Number of houses raised • Beach erosion rates • Natural systems variables • Dune height and width • Wetland areas • Natural habitats
Example: Monmouth Beach • Hazard Mitigation/Planning Checklist • Emergency response plans? – yes • Reverse 911? - yes • Building standards, codes? – yes • Enforcement of codes – improvement needed • Hazard mitigation plans? – in prep. • Coastal setbacks? - yes • Dune management? – no (volunteer beach grass plantings) • NFIP community rating system? – no • Coastal Barrier community rating? - yes
MONMOUTH COMMUNITY INDICATORS Baseline assessments Temporal trends GIS layers – spatial trends
Promote Increased Community Resiliency No Adverse Impact training (Do No Harm) -Consistent with no net loss of ecological functions -Complements all water resources programs: water quality, quantity, wetland and stormwater regulations -Makes sense on local and regional scales
Promote Increased Community Resiliency Local Ordinances/Programs/Policies -reduce impervious cover (LID) -lot coverage ordinance -open space preservation (blue acres, green acres, private funds) -fill regulations -stormwater management plans -watershed management plans
Funding for Communities to Implement Resiliency Strategies and Sustainability Concepts New NOAA Grant Volunteer communities to serve as Sustainable/Resilient Community Models by adopting coastal resiliency/sustainability principles and NAI (No Adverse Impact) policies.
