COG Climate Initiatives Background

COG Board created Climate Change Steering Committee

(2007) National Capital Region Climate Change Report (11/08)

COG Board created CEEPC - Climate, Energy

and Environment Policy Committee (2009) 2010-2012 Regional Climate and Energy Workplan (1/10)

Region Forward Compact adopted (2010) Foundation for COG’s efforts to build a sustainable

metropolitan Washington region

Draws climate related goals from Climate Change Report

EPA Smart Growth Implementation Assistance (SGIA) Program

EPA initiated the SGIA program in 2005 with three goals in mind: Support communities interested in implementing smart

growth policies;

Create regional examples that can catalyze similar projects

in the area; and

Identify barriers, opportunities and tools

EPA provides the assistance through a contractor team – not a

grant.

In 2010, COG applied to SGIA and was awarded technical assistance

to support adaptation efforts Contractor: SRA

End Product: EPA Climate Adaptation Guidebook

Objectives of the Climate Adaptation Guidebook

Increase understanding of the implications of climate change among planners, policymakers and officials in the Washington region

Provide tools to implement smart growth principles to improve regional resilience to climate change impacts

Focus on four sectors: water, transportation, land use and buildings

Observed Trends

Over the last century the average

temperature rose 3.3°F in DC, 1.9°F in MD,

and 0.6°F in Virginia (NOAA).

The Potomac Estuary has experienced one

foot of relative

sea level rise (NCPC, 2008).

In the Mid-Atlantic major weather events

increased 12-20% compared to the previous

century (UMD, 2008).

Projections indicate that these trends will continue at an increased

rate and lead to expanded riparian flood plains and coastal

inundation zones and more frequent droughts, heat waves and

record-setting events (IPCC, 2007; GCRP, 2009).

Anticipated Climate-Related Changes

Note: Reflect trends which have already been observed in recent past and are projected to continue with high confidence, except for drought frequency (medium)

Temperature Precipitation Variability

Severe Storms

Sea Level Rise

Higher average temperatures

More frequent heat waves and days over 90° F

Fewer freezing days, and warmer nights relative to days

Precipitation concentrated into fewer events

Increased precipitation variability

Possible increased frequency of drought

Increase in intensity of coastal storms, such as hurricanes and nor'easters

Sea level rise combined with local land subsidence and storm surges.

Potential Impacts to Sectors

Transportation: more frequent travel disruptions and increased damage from severe

events, change in infrastructure maintenance needs, and increased deterioration from

buckling and expansion due to extreme heat or freeze-and-thaw cycles.

Buildings: increased damage from weather-related events; increased demand for

emergency response; health impacts from flooding, storms, extreme heat, and more poor air

quality days; potential for water restrictions due to drought; increase in cooling costs and

small decrease in heating costs; possible changes in the lifetime of roofs and other structural

materials.

Land use: expansion of flood-prone areas, flood plains, and coastal inundation zones;

increase damage to natural areas from invasive species, flooding and heat waves; increase in

damage to or strain on infrastructure, including transportation, water, energy, and

wastewater.

Water: potential increased amount and/or frequency of sanitary sewer overflows and

combined sewer overflows; change in infrastructure maintenance needs; flood risks to

infrastructure; changes in water table that could affect septic fields; need for flood control

systems; increased demand on stormwater management systems; possible reduced water

supplies due to drought.

Guidebook Organization

Plan for Climate Change Tools for developing a risk/vulnerability

assessment

Regional Approaches

Local Approaches Protect vulnerable areas from development Protect people and assets in vulnerable areas Encourage sustainable growth in appropriate, less vulnerable

areas

Local Approach Example: Survivability

Recommendation: Incorporate survivability strategies into new and existing critical infrastructure such as police stations, fire stations, hospitals, schools, and emergency shelters

Survivability = ability of buildings to maintain habitability without relying on external utility systems for power, fuel, water, or sewer services, as well as being better able to withstand floods, severe weather events, and temperature extremes.

Implementation strategies may include: highly energy efficient building combined with daylighting and natural ventilation, on-site renewable energy

Langston High School/Langston-Brown Community Center in Arlington, VA incorporates passive solar, operable windows for ventilation in the event of power failures and large rainwater cisterns. (Source: USGBC)

Project Outcomes and Next Steps

Provided an opportunity to educate a broad range of stakeholders on climate adaptation

Identified the need for additional information on climate change impacts in the region

Spurred sectors to continue adaptation conversation

Climate impacts symposium planned (5/21/12)

Identifying and discussing vulnerabilities in small groups at NOAA Roadmap for Adapting to Climate Risks Training on March 3, 2011 at COG.
