Interactive Maps: Marina Suitability
The Center for Coastal Resources Management (CCRM) at the Virginia Institute of Marine Science (VIMS) developed this tool using available GIS data, government specifications and scientific information to identify appropriate sites for future marinas. GIS based algorithms were written to model marina siting criteria recommended by the Virginia Marine Resources Commission (VMRC). A team of experts including planners, regulators, environmental managers, scientists, and GIS specialists collaborated on a protocol that became the basis for the algorithms.
The protocol implements an evaluation approach which ranks existing conditions on the landscape based on three major categories: habitat, water quality, and design. Within each category, several criteria are mapped independently and ranked. For example, under the heading "habitat" the presence or absence of the following is considered: sav, wetlands, threatened and endangered species, shellfish grounds, and riparian forest. The ranking system assigns points based on presence or absence within blocks measured 600 meters longshore, 30 meters inland, and up to 200 meters seaward of the shoreline, depending on creek width. A site is evaluated for each of the three major categories. A cumulative assessment combines all three groups to complete the evaluation for each block. Three possible levels of suitability can be assigned for a site: high (desirable), moderate (desirable with limitations), low (undesirable). A series of maps illustrate the results. The delineations illustrated do not replace the need for site inspection.
Web Site Description
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 (i.e. "Summary") of all three major criteria evaluated together. A tile index is available for each of the four compositions. To access data for a specific area, click the tile (plate) on each index map.
