Coastal GEMS

What Is "Coastal GEMS"?

• A gateway to Virginia’s coastal resource data and maps; coastal laws and policies; facts on coastal resource values; and direct links to collaborating agencies responsible for current data.

• A growing inventory of water and land based natural resources, conservation planning tools, and planning examples that can help us to protect Virginia’s coastal ecosystems.

• A tool to promote community involvement and environmental education.

How Coastal GEMS came to be…

During a Virginia CZM Program workshop in 2001, state and local partners expressed the need for a “vision” of Virginia’s Coastal Zone or a comprehensive inventory of Virginia’s coastal resources.  Many questions were raised.  What is the current status of Virginia’s coastal resources?  How can these coastal resources be managed in a sustainable fashion in light of increasing development pressures?

As a first step in achieving this “vision,” our partners agreed it was important to identify and map the best remaining blue (water-based) and green (land-based) natural resources within Virginia’s coastal zone.  We began collecting spatial data and creating management tools to be included in Coastal GEMS.

The idea grew into the concept of providing a gateway, or starting point, for accessing more comprehensive coastal resource information from all of our natural resource agencies and coastal partners for consideration in planning efforts and management decisions.

In addition to funding data layer development by CZM partners, we contracted with Virginia Commonwealth University’s Center for Environmental Studies and WorldView Solutions, Inc. to create the Coastal GEMS application.  Additional data layers will be incorporated into Coastal GEMS as agencies continue to develop data and make it available for inclusion.

Who Should Use Coastal GEMS?

A major goal of Coastal GEMS is to foster stronger understanding of how activities on the land and in the water affect each other.  It is the intent of Coastal GEMS to create a stronger linkage between local land use plans and state and federal water use policies.

Coastal GEMS can be used by:

• Local and regional planning 

agencies to better manage growth by determining the most suitable areas for conservation and development.

• State and federal agencies to better manage projects such as roads and major facilities, habitat restoration, and public access plans. They could also use Coastal GEMS as a starting point for the environmental review process in order to quickly access agency data.

• Academic institutions to educate students about coastal resource use and values and to provide a basis of
information for classroom projects and/or research.

• Private citizens, advocacy groups, and businesses to formulate their positions on the potential impacts of projects on coastal resources.

• General public to learn more about Virginia’s coastal resources.
