Assessing the Decision-making Process in Wetlands Resources Management in Virginia
This study is the first step in trying to elucidate how local wetland boards have balanced the environmental charge (for which they have significant guidance) with the socioeconomic charge, where there is nothing available beyond a requirement in the act to accommodate this factor. The study aims to provide an assessment of the extent to which social and economic issues are currently incorporated in the decision-making process by the local wetlands boards, and to suggest a preliminary framework for incorporating social and economic considerations in the wetlands decision-making process. This framework is only the first step in suggesting key social and economic elements that should be considered. Further development and tests should be performed to evaluate the appropriateness and effectiveness of this framework in the near future.

Internet based decision tool for siting wetland restoration sites in Hampton Roads, VA
This project uses the protocol and findings of the Advanced Identification of Wetland Restoration sites to develop an interactive, web-based management tool to assist regulators, developers, and project agents in location of potential compensatory mitigation sites in Hampton Roads.

Wetlands Permit Review and Report Generator
This project enhances the permit reporting process to increase the amount of information presented while automating systematic reporting. This is the first system of its kind that combines expert staff review with landscape information retrieved from spatial databases. The report generator is always being modified as new landscape information is available. The reports along with the original application and related photos are posted online in a searchable database: http://www.vims.edu/ccrm/wetlands/newpermits.html

An Online Interactive Mapping Tool for Managers of Wetlands, Shoreline, and Land Use
An online, interactive GIS website will be created to allow managers with interests in Virginia's coastal resources to review environmental conditions at the desktop. The project will bring together a variety of GIS themes under one project, and provide interactive capabilities for users to build their own assessments by turning GIS themes on and off. Users will not be required to have GIS software on their own desktop, or maintain any databases. The system will be available to any individual with Internet access. The project will be served and maintained through the VIMS website.

Aquaculture Vulnerability Model
This study uses Geographic Information Systems (GIS) to model risks to shellfish aquaculture.

Blue Infrastructure
The Blue Infrastructure online mapping tool integrates important aquatic resources that have been compiled for the coastal zone of Virginia using GIS technology.

Digital Shoreline Coverage
Baseline GIS coverages in support of a statewide GIS database devoted to natural resource mapping in the Coastal Plain of Virginia. The shoreline, provides the basic boundary layer for most analysis in coastal Virginia.

Effects of Sea Level Rise on Tidal Wetlands
This project maps the anticipated loss of tidal wetlands habitat in the Lynnhaven River watershed attributed to sea level rise. The project uses remote sensing techniques and high-resolution imagery to delineate current wetlands distribution. High resolution elevation data generated from LIDAR will be used to compute the horizontal and vertical inundation due to sea level rise.

Erosion Vulnerability Assessment Tool
EVA was designed as an online interactive map interface to illustrate the output of a highly integrated spatial data model that uses multiple data sets generated by various developers across the Chesapeake Bay region. The map outputs, which can be generated on the fly, will inform local planners where community infrastructure, cultural resources, and habitat are potentially at risk in the future.

Marina Suitability
The tidal waters of Virginia were divided into 28 tiles for publication purposes. For each geographic boundary defined by a tile, there is one map for each major category: habitat, water quality, and design. A fourth map represents the cumulative landscape assessment of all three major criteria evaluated together.

Oil Spill Clean Up and Response (OSCAR)
OSCAR, the Oil Spill Clean-up and Response tool, was generated to assist individuals responding to oil spill accidents in the Chesapeake Bay.

Shallow Water Use Conflicts Tool
This project uses GIS to evaluate conditions suitable for a variety of activities that may occur within the shallow water zone of the estuary.

Shallow Water Use Management Plan
This project used GIS to evaluate conditions suitable for a variety of activities that may occur within the shallow water zone of the estuary. Uses include SAV growth, aquaculture, crabbing, recreational fishing, etc. Nearly 20 uses were modeled. First use suitability models were developed, specifying conditions which must exist for a particular use to occur. Second, GIS algorithms are prepared to analyze available environmental data and indicate areas of suitable conditions for each use within the shallow water zone. Spatial models of use suitability were then combined according to a conflict prediction model to identify potential use conflicts. Final steps in the project will be identification of management issues and options, and development of policy recommendations.

Shoreline Assessment Mapper
SAM is provided as a data resource to assist local and state government staff as they review shoreline conditions and make recommendations regarding proposed permit actions.

The Elizabeth River Environmental Atlas
The Elizabeth River Environmental Atlas is designed to be an interactive tool that will make the existing environmental and natural resource data available to resource managers and regulatory agencies.

Tidal Marsh Inventory
GIS coverage of all marshes delineated in the Tidal Marsh Inventory Series.

Tidal Wetlands Assessment - York River Assessment
This study provides baseline data on the extent and condition of 2,188 tidal wetlands within the York River Watershed. These data provide valuable information in identifying wetland restoration opportunities, evaluating appropriate mitigation ratios, and determining cumulative impacts within a watershed.

Tidal Wetlands Multi-Level Assessment
This includes reports, datasets and ArcIMS projects for Level I and II protocols within the Indian River, DE; Nanticoke River, MD, and York River, VA.

Waterfront Development and Potential Impacts to Aquatic Habitat: A Planning Tool for Evaluating Resource Sensitivity
This project considers specific criteria in a waterfront landscape that collectively appraise the potential risk of development to sensitive aquatic resources. The protocol evaluates conditions on the landscape based on three major categories: existing land use, impacts to sensitive habitat, and potential impacts to water quality.

Wetlands Data Viewer
The Wetlands Data Viewer tool allows users to obtain National Wetland Inventory (NWI) statistics for any hydrologic unit in Virginia.

Wetlands Mitigation Targeting Tool
This tool uses GIS to target sites in the landscape suitable for wetland creation. It has application for wetland restoration or mitigation projects. The tool outputs selected sites based on five suitability parameters: presence of hydric soils, presence of hydrology, adjacency to existing wetlands, existing landuse and the opportunity for landscape conversion, and proximity to designated conservation areas.
