Summary
To inventory James City County and the City of
Williamsburg tidal shoreline conditions.
Description
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 of the 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 is the first
Shoreline Inventory Report for James City County and the City of Williamsburg.
Data collected describes conditions in the immediate riparian zone, the bank,
and along the shore.

Supplemental information
There are four shapefiles that are part of the 2014 James City County and the City of Williamsburg Shoreline Inventory database:JCC_Wmsbg_lubc_2014, JCC_Wmsbg_sstru_2014, JCC_WMSBG_astru_2014 and JCC_Wmsbg_tm_2014. JCC_Wmsbg_lubc_2014 (land use and bank cover for James City County and the City of Williamsburg) is a linear shapefile containing data about land use, tree fringe, bank height, bank cover, bank stability and beach status along the shoreline. JCC_Wmsbg_sstru_2014 (James City County and the City of Williamsburg 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). JCC_Wmsbg_astru_2014 ( James City County and the City of Williamsburg access structures) is a point shapefile with locations of docks, dilapidated docks, boathouses, and private and public boat ramps. JCC_Wmsbg_tm_2014 (James City County and the City of Williamsburg tidal marshes) shows the location, size, species and type of tidal marshes. The attributes of these four shapefiles are explained in the Entity and Attribute Information section below.

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.
Limitations of
use

Data
Quality ▼►
Scope of quality information ▼►
Data quality report - Completeness omission ▼►
Measure
description This
inventory targets tidal shoreline only. Access by boat is required for field
surveys. Remote sensing techniques are used in areas where water depths are too
shallow for access or where unmanaged, undeveloped shoreline persists along
very long reaches. This would include headwaters of tidal creeks, and natural
areas along park and conservation lands.
Data quality report - Absolute external positional accuracy ▼►
Dimension horizontal
Measure
description Shoreline
attributes recorded with a GPS unit as the boat moves along the shoreline has a
horizontal accuracy of +/- 5 meters. Data was transferred from the GPS boat
track to an existing digital shoreline coverage by
projecting data to the shoreline at a 90 degree angle from the boat track.
Rectified imagery were used as a background coverage
to aid in data positioning. Land use features were placed along the shore so
changes in land use were coincident with changes illustrated in the imagery. Positional accuracy for data that has been corrected with imagery
which has a resolution of 2 meters or better. Accuracy limits of the
field collected data, however, are set at 5 meters due to the short occupancy
of GPS units. In many cases the image correction yields a final positional accuracy
much closer to 2 meters or less, depending on image resolution.
Lineage ▼►
When the
process occurred 2013-01-01 00:00:00
Description A shoreline for James City
County and the City of Williamsburg was created using 2009 VBMP imagery as a
backdrop and using ArcGis version 10.0. Using this as
a baseline the shoreline inventory was remotely generated using two sources:
2012 oblique Pictometry imagery available through
Bing Maps, and 2013 high resolution imagery available from the Virginia Base
Mapping Program (VBMP). The Tidal Marsh Inventory was updated by surveying in
the field in June 2014. Shorelines of Chickahominy River, College Creek, James
River, Mill Creek, Powhatan Creek, Queen Creek, Shellbank
Creek, Skiffes Creek, Skimino
Creek, Taskinas Creek, The Thorofare,
Ware Creek, and York River were surveyed. The shoreline was coded for land use,
bank height, bank condition, bank cover and the presence or absence of beach,
access structures and hardened structures.
When the
process occurred 2013-01-01 00:00:00
Description A
small draft boat was used to collect data in the field. Data is logged using a
geo-referenced video camera. The Red Hen System provides hardware and software
to collect geo-referenced video and photo data in the field. A standard video
camera (sony ACC-HDV7) is
interfaced with a GPS antennae via the Red Hen hardware device - VMS 300. VMS
300 converts GPS data into audio signals, which are sent to a video camera
through its microphone input connector. As the video is recorded, GPS data are
transmitted once per second to the video camera by VMS 300. Each GPS location
is linked with a time code on the video. Therefore, the survey is a set of
videos containing geographically referenced shoreline data.
When the
process occurred 2013-01-01 00:00:00
Description The Red Hen video data
was used for QAQC.

When the
process occurred 2014-06-01 00:00:00
Description All processing steps
for the shoreline inventory were done using ArcGis
version 10. Using the latest VBMP 2013 imagery as a background, conditions
visible on shore were used to code a digital shoreline created using VBMP 2009
imagery. Conditions were also verified using Bing Birds Eye and aerial imagery.
For the land use/bank cover shapefile arcs were split
and coded for land use, bank height, bank cover, bank stability, tree fringe
and presence or absence of beach, for the access structure shapefile
arcs were coded for dock, dilapidated dock, boathouse, and public and private
ramps, for the shoreline structure shapefile arcs
were coded for bulkhead, delapidated bulkhead,
riprap, unconventional, debris, wharf, breakwater, groinfield,
jetty, marsh toe revetment and marina >50 and <50 slips.
Description Used to accurately position
land use and land cover data. Provided a new digital
shoreline coverage that serves as the base shoreline for shoreline conditions.

Feature refers to a combination of land use in the immediate riparian area within 100 feet of the adjacent shoreline and best profeesional judgement when the infrastructure is setback on the parcel. Feature is labelled one of the following: agriculture, bare, commercial, forested, grass, industrial, paved, residential, timbered and scrub-shrub.

to each other. This designation can be determined using best professional
judgment.

Bank stability is an observed estimate of how stable the bank is. It is not a true measure of erosion. Characteristics that would classify a bank as being unstable are exposed roots, bare soil, slumping, and falling trees. Characteristics of a stable bank would be one that is well vegetated and absent any signs of sediment slumping, scarps, and failing trees. If the bank condition can not be discerned from the observation point, the bank stability is classified as “unknown”. Erosion is labelled one of the following: stable, unstable or unknown.
