Title: Sensitive Areas - Aquatic, Washington State Department of Transportation
Geospatial Data Presentation Form: vector digital data

Description:

Abstract:
This feature class contains environmentally sensitive areas that front state highways, including wetlands, waterbodies, streams, and channel migration zones. Roadway segments within 300 feet of a sensitive area were GPSed. The sensitive areas are represented by lines segments which have had their beginning and ending points buffered an additional 300 feet. Data has been synchronized to the LRS December, 31 2011.
Purpose:
To provide guidance to WSDOT maintenance crews so that Best Management Practices (BMPs) may be applied to eliminate or reduce impacts of maintenance activities on sensitive areas. To alert staff as to when and where to apply and report implementation of the Regional Road Maintenance Endangered Species Act (ESA) Program Guidelines (RRMP) BMPs.
Supplemental Information:
This feature class covers the entire state. The original data collected in 2000 and 2001 included North Central Region, Southwest Region, and South Central Region. Olympic Region added data in 2002. Eastern Region was added in 2003. Northwest Region collected data in 2001, but maintained it in a separate feature class. In 2005, all six regions updated their data. In 2009, Northwest Region data was combined with the rest of the state to create a single feature class.

Lineage:

Process Step:

Process Description:
Aug 2012 - Updated to the Dec. 31, 2011, LRS. In July 2012, the boundary between WSDOT's Southwest and South Central regions was adjusted. Thirty-four segments were affected. The SITE_ID, Region, and MAREA attributes for these 34 segments were updated to reflect the boundary change.
Process Step:

Process Description: April 2011 - Updated to the Dec. 31, 2010, LRS.

Process Step:

Process Description: June 2010 - Updated to the Dec. 31, 2009, LRS.

Process Step:

Process Description:
2009 EA, NC, OL, SC, SW Regions: Segments identifed as being associated with both sides of a state route were broken out into increasing and decreasing segments. Segments were then remapped using their original latitude and longitude values, except for segments in Eastern Region which didn't have latitude and longitude values available. The latitude and longitude values were converted to ARMs using the Locate Features Along Routes tool. The region and county fields were originally populated with numbers or a combination of names and numbers; the numbers were replaced with names.
NW Region: Segments were remapped using their original latitude and longitude values. The latitude and longitude values were converted to ARMs using the Locate Features Along Routes tool. A section of SR 9 which had been realigned was visited by a biologist in order to GPS the new sensitive segments. In order to combine the Northwest Region data with the rest of the state, the fields needed to be comparable. The Northwest Region dataset had several empty fields, as well as elevation values associated with the beginning and ending points of the segments. None of these fields were carried over into the combined dataset. Three fields unique to the Northwest Region dataset were BegComment, EndComment, and MAREA. These were carried over. Values in the fields corresponding to TYPE_CODE, PI_CODE, and HQ_CODE were recalculated in order to be comparable with the rest of the state. A PRIORITY field was added and calculated based on the matrix used by the rest of the state. The Northwest Region had date fields for both the beginning and ending points, which were not always the same. Only the beginning data was retained.
All Regions: Data for all the regions were combined and new unique IDs calculated. MAREA was determined for the segments in regions other than Northwest. When the 2008 LRS data became available, ARMs and SRMPs (buffered and unbuffered) were updated for all segments using the Excel version of ARMCalc. The segments were then placed on the 2008 LRS using the buffered values.

Process Step:

Process Description:
Eastern, North Central, Olympic, South Central, and Southwest Regions: 2000 - 2003: Maintenance crews GPSed beginning and ending locations of sensitive area. These points were converted to state mileposts and buffered by 316 feet or .06 miles. The types of sensitive areas were determined and a priority matrix was developed to rank sensitive areas by impact from maintenance activities.
12/2006: RSMAIncreasing, RSMADecreasing, and RSMABoth models were used to convert Lat/Long points into 2005B State Route LRS events. Error Checking was done, and the three files were merged into a complete shapefile.

Process Step:

Process Description:
Northwest Region: Field crews (transportation technicians) visit each feature in the field. The feature is located using a global positioning system receiver, feature attributes are visually determined and recorded, the feature milepost is calcuated using a distance measuring instrument and offset values are calculated using a laser range finder. For some features, images of the feature are taken using a digital camera. The features are post-processed in house by transportation technicians using Trimble software. The features are exported to shapefiles in the unprojected (NAD83) state. County and Northwest Region maintenance area values are calculated using ArcView 3.2 (ESRI) software. Mainline state route and mainline milepost values are computed using the 24k LRS and ArcMap 8.x (ESRI). The features are projected to the Washington State Plane South (NAD83) state using ESRI's ArcToolbox (8.x) software. Using ESRI's ArcCatalog(8.x) the features are uploaded to the appropriate sde. The feature attribute values are visually scanned for inconsistent and erroneous values in Sql Server Enterprise Manager.
