The Virginia Coast ZoneThe coastal zone can be
defined as a mesh between water and land.
The coastal zone is 29% of Virginia’s land including:
5,000 miles of shorelineFour tidal riversThe Chesapeake Bay Albemarle - Pamlico Sound
Over 60% of Virginians live in coastal zones
How Important is it?
A majority of Virginians live in the coastal zone area
Virginia is included in the mid-Atlantic coastal region of which 10% of the population live below one meter elevation
Virginia Beach and the fishing industries are important sources of income for Virginia
The largest navel port is located in Norfolk, Virginia
The largest estuary in the U.S. is located within Virginia, the Chesapeake Bay
Why is it important? The low elevation of Virginia’s coastal zone makes it
specifically vulnerable to sea level rise and the rising sea level will displace all those Virginian’s who live in the coastal zone
Stronger more frequent storms will negatively impact both the fishing and tourist industries.
The stronger storms will erode the coast faster than they are already eroding, resulting in less land mass. This is bad because the water level is also rising so the coastal zones will get pushed inland and the land mass will get smaller and there will be less land for humans, plants, and animals to live on.
Case Study: The Chesapeake Bay Sea level rise
The bay will see more of a sea level rise than other regions because the land is subsiding
Tidal marshes are disappearing because they cannot move ashore as fast as the water
Tidal marshes are a key part of the bay because they filter pollution from the water, help control erosion of the shoreline, and are the home to many different types of plants and animals including the blue crab
Increase in temperature Warmer temperatures mean warmer waters and less
dissolved oxygen-> less organisms can maintain their habitat
Increased precipitation Increased run-off -> increased amount of nutrients and
sediment-> decrease of water quality More algae blooms-> death of submerged aquatic
vegetation

Adaptation & Mitigation
Adaptation - Initiatives and measures to reduce the vulnerability of natural and human systems against actual or expected climate change effects.
Mitigation - Actions to reduce greenhouse gas emissions and to reduce the extent of climate change.
Observation System
Create a system which observes the changes in sea level and records information about sea level rise, its effects, its rate, and the dangers it presents both to humans and to ecosystems alike
Erosion Control And Prevention A switch from hard defenses
to soft defenses is necessary.
Soft defenses include beach nourishment, dune restoration, and shoreline stabilization. These methods both control erosion and, often times, simultaneously protect communities from high-water events.
Hard defenses, such as bulkheads, rip rap or groins, are often times more harmful then helpful.
Coastal Squeeze!
Hard defenses can trap wetlands as they try to move inland as water-levels rise
THIS CAUSES LOSS OF LAND AND HABITAT ALIKE!
Soft defenses replenish land and habitat while offering similar if not the same protection.
Restrictions on Coastal Development Coastal development
is causing an equal amount of problems for both people and the environment
High water events, coastal storms, and sea level rise cause problems for homeowners living too close to the coast
Homes too close to the coast can be considered hard defenses in and of themselves and, often times, homeowners create literal hard defenses in order to protect their home and property
Restrictions on Coastal Development Cont.
Restrictions on the zoning near any coastline must be created in order to give the coast and wetlands “breathing room”
This will allow for an easy natural migration of land and habitat if necessary as well as easy access of land to adapt it, add natural protection and soft defenses to it, and condition it for the damages global warming may cause
Mitigation
Increasingly strict admissions standards for the state of Virginia
A full force education policy
No quick fix for damage with such momentum
The key is long term policies focusing on eliminating problems
Emissions Standards As of now emissions standards are far too lenient
considering the climate change that is occurring.
As one of the states in the U.S., Virginia is responsible for doing its part in lowering harmful emissions and working towards a normal and less influenced
Emissions standards should become increasingly strict with new policies being implemented such as older cars requiring up to date maintenance to bring the greenhouse gas emissions up to the standards of modern cards.
Limitations and permits should be created for car modifications that will increase the emissions being released from the vehicle.
Education The most important aspect of solving any
large scale problem that effects the whole word or even small sections of it is education
If the youth are taught early and obtains a full understanding and appreciation for what is occurring with respect to climate change, especially when there is a focus on a particular area such as the coastal zone, there is more likely to be a long term positive change in action from them.
Give the Required Amount of Thought!
Give an appropriate amount of thought to these suggested policies
Speed? Nope!
Effectiveness? You Bet!
Inevitable Changes Rising water levels
More powerful and frequent hurricanes and storms
Precipitation changes
Warmer temperatures (water and air) that will affect habitats and coastal residents
How to adapt Rebuilding seawalls
Elevating homes
Follow the actions of other states
Reduce greenhouse gas emissions

Near Term ActionsÜ LiDAR (Light Detection and
Ranging) elevation data, which is tracked by the Virginia Geographic Information Network, does not exist for most of coastal Virginia is a major obstacle to the ability to plan effectively for these changes.
Ü The continued affordability and availability of insurance for Virginia’s landowners is a concern as our climate changes.The frequency and severity of storms in the future are expected to exceed those of the past, and the insurance industry may not have the ability to handle several concurrent events.

Near Term Actions
Residents living in coastal areas are among those who have a higher vulnerability to the health impacts caused by climate change. As such, medical assistance is a priority in this region if the situation becomes inhospitable for healthy living.
Local governments in the coastal area of Virginia should include projected climate change impacts, especially sea level rise and storm surge, in all planning efforts, including local government comprehensive plans and land use plans. 2

Near Term Actions
Transportation and critical infrastructures should ensure that climate change impacts, particularly sea level rise and storm surge vulnerability in coastal areas of Virginia, are taken into account in all transportation planning, project design, and prioritization of projects for funding as well as systems management, operations, and maintenance.
Adaptation policies and programs for the built environment should take into consideration impacts on natural systems and minimize negative impact on natural areas that are important for mitigating the impact of climate change.

29
Near Term ActionsClimate change advocates should develop a process to document climate change impacts on native species and ecosystems and recommend ways to preserve Virginia native species when feasible under conditions of climate change, while preventing the spread of invasive species.

What’s being done now? The U.S. Department of Commerce, National Oceanic and
Atmospheric Administration coastalmanagement.noaa.gov
The National Coastal Zone Management (CZM) Program is a voluntary partnership between the federal government and U.S. coastal states and territories authorized by the Coastal Zone Management Act of 1972.
The Coastal Programs Division is also responsible for advancing national coastal management objectives and maintaining and strengthening state and territorial coastal management capabilities. It supports states through financial assistance, mediation, technical services, and participation in priority state, regional, and local forums.
The Coastal Programs Division administers the program at the federal level and works with state coastal zone management partners to: Preserve, protect, develop, and where possible restore and
enhance the resources of the nation's coastal zone for this and succeeding generations
Encourage and assist the states to exercise effectively their responsibilities in the coastal zone to achieve wise use of land and water resources, giving full consideration to ecological, cultural, historic, and aesthetic values, as well as the need for compatible economic development
Encourage the preparation of special area management plans to provide increased specificity in protecting significant natural resources, reasonable coastal-dependent economic growth, improved protection of life and property in hazardous areas and improved predictability in governmental decision-making
Encourage the participation, cooperation, and coordination of the public, federal, state, local, interstate and regional agencies, and governments affecting the coastal zone.
Working with State Coastal Management Program Partners
Thirty-four coastal and Great Lakes states, territories and commonwealths have approved coastal management programs. Together, these programs protect more than 99 percent of the nation's 95,331 miles of ocean and Great Lakes coastline.
To comprehensively manage our coastal resources and balance often competing land and water uses while protecting sensitive resources, state coastal zone management programs are expected to: Protect natural resources Manage development in high hazard areas Manage development to achieve quality coastal waters Give development priority to coastal-dependent uses Have orderly processes for the siting of major facilities Locate new commercial and industrial development in, or
adjacent to, existing developed areas Provide public access for recreation Redevelop urban waterfronts and ports, and preserve and
restore historic, cultural, and aesthetic coastal features among others
In 1990, Congress created a new program under the Coastal Zone Management Act, called the Coastal Zone Enhancement Program. The program provides incentives for states and territories to make changes in any of eight areas of national significance
Coastal Nonpoint Pollution Control Program is important also. Authorized by Section 6217 of the Coastal Zone Act Reauthorization Amendments of 1990.
This amendment requires states and territories with approved coastal zone management programs to develop and implement programs to control nonpoint source pollution from six main sources: agricultural, forestry, urban development, marinas, hydromodifications (such as dams or stream channel modifications), and the loss of wetland.
