Project Title:

Shoreline Management Planning 

Project Description as Proposed:

A Shoreline Management Plan (SMP) comprises 5 major elements:  a shoreline inventory, a shoreline evolution study, recommendations for shoreline management options using a cost effective geospatial decision tool, a general cost estimate and schematics for specific types of shoreline treatments, and background review on the state of the shoreline including general geology and characteristics of the coastal land use.  Shoreline Inventories and Shoreline Evolution Reports, which provide independent data that feed models and envelope the full breadth of a SMP, have been generated for many localities in the coastal zone of Virginia.  These activities must continue in tandem with the development of the first SMPs to insure that all data necessary to accomplish comprehensive shoreline planning across all coastal localities into the future remains current and available. 

 

Therefore, the scope of work proposed for this project includes several aspects of the data development as well as final SMP products for selected localities.  A review of existing products to support SMP development was undertaken.  Consideration of data currency, completeness, and consistency with data protocols and model needs was essential.  Based on this review the following activities will be targeted.

 

One new Shoreline Evolution Reports for the County of Stafford.  An expanded Shoreline Evolution Report will be developed for Accomack County to include the secondary tributaries and creeks.  A new Shoreline Inventory for Gloucester County will be generated.  Updates to the Shoreline Inventory for Stafford County will also occur.  The last inventory for this locality was completed in 2006.  Finally we will use these data and data previously collected to generate Shoreline Management Plans for James City and Stafford counties. 

 

Expanding on work previously conducted along high energy shorelines, the Shoreline Evolution Report for Accomack County will be expanded to include the moderate to low energy shorelines.  The analysis will complete the historic shoreline change for all tidal shoreline in this locality.  This is a critical element for completion of the SMP since the majority of shoreline for this county resides within low to moderate fetch zones.    Much of Accomack County’s shoreline is undeveloped marsh.  This type of coastal zone is very difficult to orthorectify and mosaic since there are so few ground control points and tie points between photos.  In addition, the sinuosity of the marsh shoreline and associated tidal creeks mean a great deal more digitizing of the shoreline than on a typical straight shoreline.

 

A Shoreline Inventory will be developed and/or updated for Stafford County and Gloucester County.  This activity will provide the necessary data to run the geospatial Shoreline Management Model; a major component of the SMP.  The activity includes data collection, processing and map production.  Development of an interactive map interface in lieu of digital maps in pdf format will be adopted for these inventories as the product deliverable.  This change was explored previous funding periods with positive and enthusiastic feedback from localities.  We therefore will continue to develop map viewers in place of pdf maps in the future.   

 

Two SMPs will be generated during the grant period.  Stafford County and James City County Shoreline Management Plans will be published.  Data for Stafford will be updated in this year’s activities.  James City is under development at this time.  Therefore, both localities will have recent field data collected which can support nearly all modeling and analysis necessary. 

 

The project year will include field work, data collection, data processing and analysis, as well as data and report publication. SMPs will be made available electronically and distributed to the local governments on CD and posted to the VIMS website.  Baseline data, where appropriate will be delivered to CZMP for inclusion in Coastal GEMS.

Project Summary Provided by Grantee:

Products that support shoreline management planning at the local level include: the Shoreline Inventory, the Shoreline Evolution Report, and the Shoreline Management Plan.  Individually, each one of these contributes to a better understanding of the condition of the shoreline, how it has evolved over time, and how it should be managed into the future to sustain important ecological services from which humans derive benefits.  This project has funded the development of locally derived shoreline inventory data for Stafford County and Gloucester County, Virginia.  The data are available to the public through the following website: http://ccrm.vims.edu/gis_data_maps/shoreline_inventories/index.html.  These data describe land use along the shoreline, the stability of the shoreline, where the shoreline has been stabilized to counter erosion, and the general shoreline morphology.  Products associated with the Stafford County Shoreline Inventory and the Gloucester County Shoreline Inventory have been delivered to the local government in digital and hardcopy format. 

The Accomack County, and Stafford County Shoreline Evolution Reports expand work previously done on primary shoreline into the sheltered tidal creeks and tributaries.  The evolution report traces shoreline change using historic photographic dating back as far as the 1930s.  Documented changes illustrate how the shoreline has responded to natural and anthropogenic stressors such as storms and shoreline hardening.  The Evolution Report and digital data can be downloaded from this link: http://www.vims.edu/research/departments/physical/programs/ssp/shoreline_evolution/reports/index.php. Hard copies are delivered to the Planning Office and the Office of the County Administrator.  

Using both modeled and field assessments, Shoreline Management Plans provide information to guide management of tidal shoreline at the local level. These reports characterize the shoreline’s geology, morphology, and wave climate; while providing specific guidance on tidal shoreline erosion control.  Shoreline Management Plans advocate an ecosystem based approach to shoreline management to strengthen coastal resiliency and long term sustainability of important ecological services.  Final products under this grant include the James City County and the Stafford County Shoreline Management Plans.  Both should be used to help guide decision making and policy development into the future.  They are available on this site:

index.php. County Administrator and the Planning Office for both localities receive hardcopies of the plan.
