Advancing High Resolution Coastal Forecasting & Living Shorelines Approaches in the Northeast
The Advancing High Resolution Coastal Forecasting and Living Shorelines Approaches in the Northeast advances northeast regional forecasting for inundation from storms under future sea level rise scenarios and identifies policy barriers and potential solutions for the use of living shorelines in the northeast.
Connecticut Physical Climate Science Assessment Report
Researchers are reviewing the current state of scientific knowledge of recent trends and projections of local climate (temperature and precipitation), with a purpose to inform planning and adaptation by the state, municipalities and local governments, commercial enterprises and NGOs in Connecticut.
CRCOG – Capitol Region Natural Hazards Mitigation Plan Update
The Capitol Region Council of Governments (CRCOG) was awarded Pre-Disaster Mitigation grant funding from FEMA to update a multi-jurisdictional natural hazard mitigation plan by mid-2019. CIRCA’s Matching Funds award is being used to support the plan update. Goals of the plan update are to: 1) assist participating municipalities in assessing risks and local capabilities related to natural disasters, and evaluating and establishing mitigation strategies including policies and actions that can be implemented to reduce risk and future losses from floods, dam failure, drought, forest fires, winter storms, hurricanes, tornados, windstorms, earthquakes, sea level rise and other natural hazards identified through the planning process; and 2) create a FEMA-approved natural hazard mitigation plan update that will enable participating municipalities to apply for FEMA hazard mitigation project grants. CIRCA funds will support public outreach efforts and inform the assessment of local and regional risks.
East Lyme – Coastal Resilience, Climate Adaptation, and Sustainability Project
The Town of East Lyme seeks to enhance community sustainability and resilience to the impacts of climate change, sea level rise, and extreme weather by developing specific policies and recommendations for inclusion in the town’s Plan of Conservation and Development. This CIRCA grant project will create a new Flood Ordinance and establish a Flood Commission made up of members from the Board of Selectman, Zoning Commission, Planning Commission, and local professionals such as engineers, surveyors, and insurance professionals. The project will also: 1) identify adequate freeboard requirements (or factors of safety expressed in feet above a flood level) and areas in need of increased safety in anticipation of sea level rise and climate change; 2) identify projects such as living shorelines within East Lyme that advance resiliency; and 3) update the town’s Geographic Information System mapping to incorporate Coastal A-Zones, municipal wastewater infrastructure, CIRCA site suitability for living shorelines, and other flooding data. The project will build on recent work by The Nature Conservancy and also leverage completed CIRCA research projects. Outcomes can be used as a model for other coastal communities and not only increase East Lyme’s resilience and sustainability by establishing sound land use policies and regulations, but may also improve the town’s community rating within the National Flood Insurance Program.
Financing Resilience in Connecticut: Current Programs, National Models, & New Opportunities
The Financing Resilience in Connecticut: Current Programs, National Models, and New Opportunities literature review and fact sheet provide information on existing resilience financing programs in Connecticut and model programs that can be applied in the State to educate municipalities, regulators, policymakers, and legislators on financing options.
Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, & Policy
The Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, and Policy project provides information for wastewater system vulnerability assessments, combined river and coastal flooding for pilot sites, and policy options for priority resilience projects for towns in the Sandy-impacted counties.
New Haven Industrial Toolbox
The City of New Haven is a coastal town with repetitive flooding problems. In response to frequent flooding, the City organized the Program for Public Information, a committee charged with making recommendations to help address flooding issues.
NHCOG – Building Municipal Resilience & Climate Adaptation Through Low Impact Development
With flooding, erosion, and sedimentation becoming an increasing concern for Northwest Connecticut towns, the Northwest Conservation District supported by Northwest Hills Council of Governments staff, coordinated the creation of a Low Impact Sustainable Development (LISD) Design Manual. The manual, designed for the town of Morris Planning & Zoning Commission and drafted by Trinkaus Engineering, LLC, describes the need for the LID approach, engineering specifications for successful systems, and sample enforcement tools.
NHCOG – A Vision and Toolkit for Adaptation in the Northwest Hills
The Northwest Hills Council of Governments (NHCOG) received an award for its project, “Enhancing Rural Resiliency: A Vision and Toolkit for Adaptation in the Northwest Hills.” NHCOG and regional partners will use CIRCA’s support to craft a vision of A Resilient Northwest Hills and produce a web-hosted climate change adaptation toolkit for municipalities. As a region of 21-towns, the Northwest Hills will experience a variety of climate changes including changes to precipitation rates, shifts in seasons, increased high heat and high-ozone days, and extreme weather events. The NHCOG’s Municipal Resilience Grant project is consistent with their 2017 regional Plan of Conservation and Development, which specifically identifies climate change-related policies and specifically lists preparing, “a climate change adaptation plan including a web-based toolkit” as a strategy to help achieve the goal. While this project achieves several regional objectives, it will also be highly transferable to other towns in Connecticut.
Public Support for Adaptation to Sea Level Rise
The Public Support for Adaptation to Sea Level Rise project will survey Connecticut coastal residents to examine their preferences and values with respect to various measures to preserve coastal areas and resources in the face of sea level rise.
Real Estate Values, Tax Revenues, and Climate Change-Induced Retreat from Flood Zones
What is the cost of preserving, maintaining, or restoring coast-front (vulnerable) properties? This proposal outlines an approach to ascertain the value of oceanfront status for homes located near the coast.
Resilient Coastal Communities under Wind & Flood Hazards
The Resilient Coastal Communities under Wind and Flood Hazards project will evaluate and compare trade-offs in residential home building designs to reduce risk of wind and flood damage in order to reduce coastal community vulnerabilities. The towns of Fairfield and Milford are participating in the study.
RiverCOG – Long Term Recovery and Land Use Resiliency through Community Flood Resilience Study
The RiverCOG is developing a Regional Long Term Recovery and Land Use Mitigation Plan for 17 towns based on real-time data and forecasts, mapping, and best management engineering practices for infrastructure (transportation, water, wastewater, utilities) as they relate to resilience in land use policies and climate adaptation. The Plan will create a template for towns to incorporate land use and infrastructure policies that will improve resiliency from natural hazard events and a strategy for long term recovery efforts after natural hazard events, specifically those that cause coastal and riparian inundation.
SAFR Connecticut Connections Vulnerability Assessment & Resilience Concept – National Disaster Resilience Competition (NDRC)
The SAFR Connecticut Connections Vulnerability Assessment and Resilience Concept – National Disaster Resilience Competition (NDRC) developed a climate change and extreme weather vulnerability assessment for the coasts of New Haven and Fairfield counties and a resilience concept for using the natural high ridgelines of Connecticut to connect low-lying coastal communities to resilient transit-oriented development along Metro North.
SCRCOG- Climate Adaptation and Resiliency Planning for Protection of Public Drinking Water
In this project the South Central Regional Council of Governments (SCRCOG) will integrate climate change information into water planning processes for the region as well as develop an adaptation plan for this essential sector for the SCRCOG region and the South Central Connecticut Regional Water Authority.
With changing precipitation patterns, sea level rise, and drought anticipated due to climate change, water resource managers will benefit from integration of climate data into planning. The SCRCOG will work with regional planners, utility water managers, and climate science experts to identify climate risks and thresholds of importance to the regions water utilities, conduct a historical climate data analysis for the region, and prepare/analyze future climate projections and impacts. Using a scenario approach SCRCOG will assist water utility managers as they incorporate this data into planning activities.
SCRCOG will also create a guide for other regional entities and/or municipalities considering integration of climate change data into planning efforts.
SCRCOG – Design and Technical Guide for Implementing Innovative Municipal Scale Coastal Resilience in Southern Connecticut
Coastal adaptation and resilience planning at the municipal scale faces multiple challenges including concerns with the tax base, lack of decision support tools, and gaps in valuing urban ecosystem services. This CIRCA grant project seeks to overcome challenges that practitioners, planners, and policymaker’s encounter by using coastal adaptation strategies applied to projects in Old Field Creek in West Haven and Cosey Beach in East Haven. These two projects build on past efforts of the Regional Framework for Coastal Resilience in Southern CT and the Yale Urban Ecology Design Lab (UEDLAB) project funded by The Nature Conservancy.
Sites in West and East Haven are at different stages in planning and each is distinct in population density, hydrology, erosion and wave patterns, and types of habitat. Building on previous experiences and findings, a core group of landscape architects, regional planners, land use attorneys, economists, and engineers will work closely with the municipalities to create initial design proposals and leverage the planning process developed as part of the Regional Framework for Coastal Resilience. Outcomes will include a Design and Technical Guide based on evaluation from an Economic Analysis/Decision Making Support Tool. The Design and Technical Guide will be integrated into the municipal planning process. These outcomes will help transition municipalities driven by hard infrastructure, road transportation and developer-driven housing to spaces created with equity, human health, ecosystem function, and climate change as drivers of planning and design.
Stamford – Resilience Opportunity Assessment
The City of Stamford was awarded a CIRCA grant for its “Resilience Opportunity Assessment” for a pilot project to review the potential vulnerability to climate change hazards at the Stamford Government Center and Stamford High School. Government Center is where the majority of City operations are housed the school is one of several locations serving as a public emergency shelter during blackouts and storms. The City is partnering with New Ecology, Inc., a Hartford-based non-profit that has developed a resilience assessment process for identifying hazards (including flooding, erosion, drought, extreme heat and cold, storms, fires, etc.) and implementation priorities (including but not limited to: elevating mechanical and electrical equipment, flood proofing buildings, flood barriers, perimeter drains, backflow preventers, portable water storage, etc.). The product of this CIRCA Municipal Resilience Grant will be a set of recommendations for mitigation approaches ranked in terms of cost, risk, and vulnerability for these two buildings. This pilot assessment will not only provide an opportunity to advance resiliency in specific municipal buildings, but an opportunity to improve how the entire City functions and recovers from possible disaster.
WestCOG – Regional CRS Program
In order to stem the high cost of flooding to home and business owners, the Federal Emergency Management Agency (FEMA) offers flood insurance in communities that comply with basic floodplain management standards through the National Flood Insurance Program. Communities may choose to enter into the National Flood Insurance Program’s Community Rating System (CRS) in order to reduce the cost of flood insurance premiums for their property owners. Communities participating in the CRS Program go above and beyond the minimum standards and, depending on their level of mitigation efforts, can garner insurance premium reductions from 5-45%.
