Climate change is here to stay, at least for the foreseeable future. Yet carbon dioxide levels continue to climb, now above 400 parts per million, and the consequences are already devastating. The year 2015 was the hottest on record for the planet. The sea level is rising faster in the Gulf of Maine than almost anywhere else on Earth. Record drought and wildfires, stronger storms and unpredictable snowpack and flooding are becoming the norm across the nation. Rising tides, storm surge and recurrent flooding are impacting coastal properties valued at over $39 trillion on the Eastern Seaboard. States are witnessing dramatic changes to land cover, fish and wildlife and habitat, water systems, agriculture and outdoor recreation opportunities because of climate change.
There are several types of tools that states can employ for climate adaptation, including: planning such as comprehensive plans and approaches to adaptation; regulatory tools such as building codes, growth plans, setbacks, buffers; spending tools such as capital improvements and land acquisition; and tax and market-based strategies such as tax and other incentives. It is critical for states to assess their own climate impacts and to put policies in place to adapt to the climate changes that are occurring. NCEL provides numerous resources, experts and examples of successful state adaptation strategies to protect natural systems, wildlife, habitat, infrastructure and health and safety.
1) Natural solutions to climate change damage are often the cheapest, most effective, most socially acceptable and provide the most benefits. For example, wetland and stream restoration can provide protection from storms and flooding, and also enhance water and air quality.
2) Commercial enterprises such as commercial fishing, forestry, pollination, skiing and other outdoor recreation, and all coastal tourism and infrastructure depend upon strong climate adaptation strategies. The outdoor recreation economy alone brings in over $646 billion per year.
3) Protection and creation of large landscapes and wildlife corridors protects wildlife attempting to adapt to climate changes, as well as provides many “ecosystem services” such as sediment and erosion control, pollinator habitat, and recreation and wildlife viewing opportunities.
4) The cost of the California drought in 2015 was $2.7 billion and 21,000 jobs. Water conservation, urban forest management, green infrastructure and collection and analysis of snowpack and streamflow data are all useful adaptation strategies for water issues.
State legislatures can provide state agencies and local communities with the tools to implement climate adaptation plans and mitigation strategies. Legislators can also create state interagency councils to facilitate more effective communication, provide funding for local or private entities, and require climate change as a facet of land use planning. Click the first drop-down menu below for a list of enacted legislation related to climate adaptation, and use the second drop-down menu for examples of state stormwater codes to combat increased flooding from climate change.
Requiring state agencies to ensure that state investments are resilient to climate impacts:
- Maryland, HB 615 creates the Coast Smart Council to oversee state infrastructure projects and requirements that new and reconstructed state facilities be planned, designed and sites to avoid or minimize future flood damage.
- New York Community Risk and Resilience Act requires the NY Department of Environmental Conservation to develop official sea level rise projects for the state. The law also requires state agencies to consider future climate change risk in specific state programs including: state funding for land preservation and acquisition, smart growth requirements, state clean water and drinking water revolving funds, siting of hazardous substances, and local coastal programs, among other programs.
- Federal Requirements: FHWA has proposed rulemaking to require states to consider climate change in risk-based asset management plans, which will be required for federal transportation dollars. FEMA guidance now requires states to consider climate change in state Hazard Mitigation Plans, which are required to receive federal disaster recovery aid. Federal Flood Risk Management Standards will require projects built with federal dollars to be elevated.
Creating state interagency councils:
- HI, Act 83 establishes an interagency adaptation committee to develop a sea level rise vulnerability and adaptation report addressing statewide impacts to 2050.
- Maryland, HB 514 codified the state’s Commission on Climate Change.
- New Hampshire, SB 163 established the Coastal Risk and Hazards Commission to make recommendations of legislation needed to protect coastal communities from sea-level rise and extreme weather.
Providing funding or financing for local or private adaptation initiatives:
- CT ShoreUp Connecticut revolving fund to provide loans to elevate homes and flood-proof businesses.
Requiring localities to consider climate change in local comprehensive plans that drive land-use decisionmaking:
- Virginia Legislation (SB 1443) requires localities in the Hampton Roads region to consider risks from sea level rise and recurrent flooding – but not sure why the legislation was limited to this region. Communities all along the Bay will be vulnerable to flooding from sea level rise, and inland communities may also experience greater risk of flooding from increased precipitation.
- Florida passed legislation giving local governments the option of designating Adaptation Action Areas in their comprehensive plans to designate areas at risk of sea level rise and other impacts of climate change, to adopt strategies to prepare those areas for impacts, and to direct and prioritize those areas for resilience investments. Florida also passed SB 1094 requiring local governments to consider sea level rise in the coastal element of their local comprehensive plan.
- California passed legislation (SB 379) requiring cities and counties to include and climate adaptation and resilience strategy into local land-use plans
Providing grants and technical assistance to help local governments plan for climate change:
- CA developed the CalAdapt tool to provide climate science and data to local governments and provides technical planning grants to update local coastal management plans.
- CT enacted legislation (Act 13-9) required the state Department of Energy and Environmental Protection to collect climate data and report on climate adaptation efforts within the state. The legislation also created the CT Center for Coasts to conduct research, outreach and education on protecting coastal ecosystems and properties from the effects of sea level rise.

State and Local Stormwater Codes
- Maryland has a comprehensive Stormwater Management Plan, available here. The Plan is based on Maryland’s Stormwater Management Act of 2007 and the Watershed Protection and Restoration Program (HB987) which was signed into law in April 2012. SB 863 in 2015 revised the 2012 law to give more flexibility to local governments to enact their own watershed protection programs.
- Iowa has a state and locally funded voluntary program for dealing with stormwater, “Rainscaping Iowa,” available here. The state portion of the funding comes from the Iowa DNR State Revolving Fund, and more information is available here.
- Portland has a “Grey to Green” program which helps to deal with stormwater through green infrastructure as part of its Sustainable Stormwater Program, available here, and as part of its Innovative Wet Weather Program that was funded by an EPA grant, available here.
- The new Seattle Stormwater Code and Manual became effective on January 1, 2016. The code includes green stormwater infrastructure, and requirements for drainage plans by new developers. The new code can be viewed here. Also see Seattle’s “Rainwise Program” for managing stormwater at home here.

Wildlife corridors and wildlife crossings can be a simple and essential component of adaptation to climatechange. Wildlife corridors protect not only wildlife, but plants, water sources, soil, forest cover and habitat. Wildlife crossings pay for themselves in reduced risk to human safety from vehicle collisions, and they provide critical movement and migration paths for animals and plants. Examples of state legislation and other resources are available here.
Mature trees and the urban tree canopy are at risk from climate change. The Georgetown Climate Center produced an Urban Heat Toolkit to help local governments identify strategies for adapting to increased temperatures in urban environments – Chapter 5 starting at p. 44 is on Urban Forestry and the toolkit can be found here.
