Description:

Abstract:

Shoreline Situation Reports (SSR) were first generated by VIMS in the 1970's to report the condition and status of the shore lands. The SSR series were published in hardcopy on a county by county basis for each Tidewater Virginia localities. The reports were intended to assist planners, managers, and regulators in decisions pertaining to management of coastal areas and natural resources therein. This Shoreline Inventory report continues a process which updates and expands the earlier reports. Data collected reports conditions surveyed in the immediate riparian zone, the bank, and along the shoreline. Virginia's beaches will be served as an individual shapefile.

Purpose: To inventory Virginia's beach shorelines.

Supplemental_Information:

There are five shapefiles assocaited with Henrico County inventory database: Henrico_lubc_2017, Henrico_astru_2017,Henrico_sstru_2017, Henrico_tm_2017, and Henrico_beaches_2017. Henrico_lubc_2017 (land use and bank cover for Henrico County) is a linear shapefile containing data about land use, tree fringe, bank height, bank cover, bank stability and beach status along the shoreline. Henrico_sstru_2017 (Henrico County shoreline structures) is a linear shapefile delineating hard structures in place at the shoreline (bulkhead, dilapidated bulkhead, riprap, wharf, unconventional, debris, marina < 50 slips, marina > 50 slips, jetty, marsh toe revetment, groinfield and breakwaters). Henrico_astru_2017 (Henrico County access structures) is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. Henrico_tm_2017 (Henrico County tidal marshes) shows the location, size, species and type of tidal marshes in Henrico County. Henrico_beaches_2017 is a linear shapefile showing the presence of beaches on the shoreline of Henrico County. The attributes of these five shapefiles are explained in the Entity and Attribute Information section below.

These data should not be used for jurisdictional permit determinations beyond providing general shoreline condition or status information. These data have not been surveyed to property boundaries.The Comprehensive Coastal Inventory Program (CCI) at VIMS performs a service by distributing data generated by either CCI or public agencies which offer data without restriction or charge. CCI assumes no responsibility for data accuracy or precision, metadata completeness or correctness for digital information. CCI assumes no liability for misuse of any data which may arise as a result of any alteration, conversion, or combination with other data sources. As well, the timeliness and scale of these products must be considered when evaluating appropriate use.

Process_Step:

Process_Description:

All processing steps for the shoreline inventory were generated using ArcGIS - ArcMap v10.2.2 while viewing conditions observed in 2015 Bing high resolution oblique imagery and 2013 imagery from the Virginia Base Mapping Program (VBMP). Using the latest VBMP 2013 imagery as a background, conditions visible on shore were used to code a digital shoreline created using VBMP 2013 imagery at a scale of 1:1000. Conditions were also verified using Bing Birds Eye and VBMP 2009 imagery. Beaches are coded as linear features at the seaward edge of the beach. ‘Wide’ beaches have at least 10 feet of dry sand persistently visible above high tides.

Process_Step:

Process_Description:

The first and second step in the QAQC process involves complete checks of shoreline coding by a GIS Programmer/Analyst and a Marine Scientist.

Attribute:

Attribute_Label: Beach

Attribute_Definition:

Beaches are persistent sandy shores that are visible during high tides.These features can be wide or thin lenses of sand. Beaches are coded as linear features at the seaward edge of the beach. ‘Wide’ beaches have at least 10 feet of dry sand persistently visible above high tides. Beach features coded along tidal marsh shorelines are persistent, sandy features located on the water side of tidal marsh vegetation. Sand washed into tidal marshes is not coded as a beach if the marsh vegetation &/or marsh edge is still clearly visible. This classification of beaches along tidal marsh shorelines can include professional judgment.
