Title:: Noise Walls - Built, Washington State Department of Transportation
Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:: Noise walls are free-standing barriers built parallel to a highway. They are usually found near public areas, such as parks, and residential areas. The walls range in height from 6 to 20 feet, but are normally 12 to 15 feet tall. They can reduce noise levels by 10 to 15 decibels, cutting the loudness of traffic noise in half. Barriers can be formed from earth berms, or constructed of wood, stucco, concrete, masonry, metal, or other materials. This feature class contains Type I and Type II noise walls that have been constructed. This data has been synchronized with the LRS dated December 31, 2018. Data appended September 2019
Purpose: Spatial data for mapping and analysis purposes.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: If data came from a plan sheet the accuracy is to 1/100 of a mile or approximately 53 feet. If the data was added from SR View photos the accuracy is approximately 2/100 or a mile or 106 feet.

Process_Description:: Noise Wall data were compiled in an Excel spreadsheet. Updates were provided by the Air, Noise, and Energy Program. Updates included aligning the walls to the 2016 LRS. Walls were checked using the SR View Application and corrected if needed.

Process_Description:: Updated to December 31, 2011, LRS. The field "Offset" was removed and replaced by "DisplayOffset". "DisplayOffset" is for display purposes only and is not a reflection of a wall's actual offset from a state route.

Process_Description: Updated to December 31, 2014 LRS

Process_Step:

Process_Description:: Noise wall data were compiled in an Excel spreadsheet. The first step in the conversion to GIS data was to add a unique Id field ("ID") to the current and proposed data sets. Separate files were created for noise walls in the increasing and decreasing directions for later use in ArcMap. Two approaches were used to get the data from Excel to ArcMap. The files for the current noise walls were converted to dbfs. The files for the proposed noise walls were converted to Access tables. The dbfs and Access tables were then added to ArcMap. The "Add Route Events" tool was used with the offset option to create event themes from the current and proposed, increasing and decreasing noise walls. The option "generate a field for locating errors" was used; it's found under "Add Route Events" advanced options. The current noise wall event themes were then converted to shapefiles and merged, and the proposed noise wall event themes were converted to feature classes and merged.
