In 2007, Washington State legislators requested a trails database, but funding to complete that statewide project was not made available at the time. In 2009, the Federal Government outlined the need for trails database schema in their Data Standards Review Committee, stressing the efficiency in management decisions that a streamlined database can provide. “The collection, storage and management of trail related data are important components of everyday business activities in many federal and state land-managing agencies, trail organizations and businesses. From a management perspective, trails data must often mesh closely with other types of infrastructure, resource and facility enterprise data.” In 2014, the Washington State Office of the Chief Information Officer's (OCIO) Geospatial Program Office acquired a Nonhighway and Off-Road Vehicle Activities (NOVA) Program grant through the Washington State Recreation and Conservation Office (RCO) giving the OCIO initial funding to develop a statewide trails database based on Federal Geographic Data Committee standards. Using the same standard for all trails data will allow land managers and recreational users throughout the state to access and use the data regardless of administrative boundary. "Data standards will make it easier for trail information to be accessed and exchanged and used by more than one individual agency or group…Ease in sharing data increases the capability for enhanced and consistent mapping, inventory, monitoring, conditions assessment, maintenance, costing, budgeting, information retrieval, and summary reporting for internal and external needs.” Along with streamlining data and facilitating efficiency in management practices across agencies, the database will provide a source of trails information that is open and free to the public. The 2016 State Legislature provided additional funding from the Nonhighway and Off-road Vehicle Activities Account to the Office of the Chief Information Officer to continue work on the database. Additional details about the project can be found here: http://rco.wa.gov/recreation/WashingtonStateTrailsMap.shtml Please note that this map and its component services have been designed to work together as part of the web application.

The National Highway Freight Network (NHFN) consists of four components: 1. Primary Highway Freight System (PHFS): This is a network of highways identified as the most critical highway portions of the U.S. freight transportation system determined by measurable and objective national data.2. Other Interstate portions not on the PHFS: These highways consist of the remaining portion of Interstate roads not included in the PHFS. These routes provide important continuity and access to freight transportation facilities.3.Critical Rural Freight Corridors (CRFCs): These are public roads not in an urbanized area which provide access and connection to the PHFS and the Interstate with other important ports, public transportation facilities, or other intermodal freight facilities.4. Critical Urban Freight Corridors (CUFCs): These are public roads in urbanized areas which provide access and connection to the PHFS and the Interstate with other ports, public transportation facilities, or other intermodal transportation facilities.States and in certain cases, Metropolitan Planning Organizations (MPOs), are responsible for designating public roads for the CRFCs and CUFCs in accordance with section 1116 of the FAST Act. This GIS dataset includes the last two components of NHFN network, Critical Urban Freight Corridors and Critical Rural Freight Corridors. Another GIS dataset is also available and published for the NHFN PHFS and Non-PHFS Interstates. The data source is FHWA and original GIS shapefiles were acquired through FHWA’s National Highway Freight Network Tool in December 2019: https://usdot.maps.arcgis.com/apps/webappviewer/index.html?id=c4c0fdef029a4093b169e493e1883988

The truck freight economic corridor designation is built upon Freight and Goods Transportation System (FGTS) tonnage classification and takes into account freight system resiliency and first/last mile connectivity to freight land uses and facilities. A truck freight economic corridor designation helps understand how freight connectors are being used by industry, and informs future planning efforts to identify the needs and opportunities for improving those connectors. This designation includes three components: 1) High volume truck corridors: T-1 and T-2 freight corridors that are defined in the FGTS as carrying at least four million tons of gross truck tonnage per year; 2) Alternative freight routes: routes that serve as alternatives to primary cross-state freight routes during severe weather or other disruptions to increase freight system resiliency; 3) First/last mile connector routes: truck routes that connect freight-intensive land uses to T-1 and T-2 freight corridors, and alternative freight routes. First/last mile connectors provide important freight linkages to strategic national defense facilities, significant intermodal facilities, warehouse districts, industrial land and distribution centers, and agricultural processing centers, and the National Highway Freight Network.

A point dataset of historical test borings drilled by the WSDOT Geotechnical Office and consultants to WSDOT. This dataset has links to boring log pdfs. The borings in this dataset were drilled before the use of gINT database software. The locations of the borings in this dataset are approximate and are not implied as having any specific spatial accuracy. They were located using one of the following processes: georeferenced historical plan sheets, alignment with stationing and offset, address description or coordinates. This data should only be used as reference. The dataset is not a complete set of historical borings. Borings are continually being added project by project as needed.

WSDOT's Corridor Sketch Initiative is a set of planning activities that engages the agency's partners to determine the context and performance of state highway corridors and identify high-level strategies for addressing performance gaps. The initiative complements and supports regional planning processes around the state and serves as the foundation for practical solutions and integrated scoping. WSDOT uses the results of the Corridor Sketch Initiative to determine where the agency should do more in depth planning and analysis. For more information on the Corridor Sketch Initiative, go to https://wsdot.wa.gov/engineering-standards/planning-guidance/planning-study-guidance/corridor-sketch-initiative. WSDOT divided the state's highway system into 304 functional segments that serve communities, economic regions and regional networks. The agency considered traffic characteristics, Freight and Goods Transportation System classification, access management, roadway characteristics, seasonal closures, land use, and proximity to intermodal centers such as ports or transit centers.

This dataset is to inform WSDOT and other state agencies of a known invasive species currently found in Washington State waterways. The New Zealand Mud Snail (NZMS) has been identified in a number of locations throughout the state. If in-water work is necessary within water bodies or connecting tributaries within a two-mile radius of the documented location (latitude and longitude), all personal gear (waders, tools, instruments, etc.) and heavy equipment must be fully decontaminated before being used at any other site. Transport to a secure site for cleaning/decontamination is allowed as long as precautions are taken to avoid any dropping of mud or debris between the work site and the cleaning/decontamination location.This dataset is used as a general reference layer for geographic information systems at the Washington State Department of Transportation (WSDOT). It is maintained by the WSDOT ESO office. Updates to this dataset are on an as needed basis.

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 April 2022

The 2,717 state highway bridges incorporated into this study from the WSDOT bridge inventory database were assessed using the BSST analysis methodology detailed previously in this report. Results consist of three types of outcomes: Bridge Damage Levels and Types, Bridge Repair Types, and Bridge Reopening Times. All output is a part of this feature class. Bridge damage types are projected on the basis of both damage level (None, Moderate, Significant), whether a bridge is a special bridge type, and also the types of damage that the bridge will experience (including both direct seismic and secondary earthquake-induced impacts); The projected repair types and reopening times necessary to bring bridges back to a minimum level of functionality that enables their use for emergency response were computed using the methodology specified in the Bridge Reopening Times section. Refer to the BSST Technical Report. The BSST was developed to assess the potential impacts of a CSZ earthquake to highway bridges in Washington State at a system-level as part of the Washington State Transportation Systems RRAP project. The results provided identify the Damage Levels, Damage Types, Repair Types and Reopening Times associated with 2,717 bridges located in Western and Central Washington that were evaluated for this RRAP project. Understanding that this analysis likely constitutes a “worst-case scenario” with respect to bridge damage, the results nonetheless project that the majority of bridges in Washington State will experience moderate to significant damage resulting from a CSZ earthquake. While the majority of bridges that experience damage could be reopened within one year of the earthquake, a substantial number of those bridges (28.7 percent) are projected to take more than a year to reopen—in many cases 2 or more years. The results also project that while many bridges may be reopened after either minor repairs/inspections or the construction of a temporary bypass road, a substantial number of more significantly damaged bridges (797 structures) span bodies of water and will require complete replacement prior to reopening. This suggests that significant gains in roadway corridor reopening times could be gained by focusing on retrofits or upgrades to these more vulnerable bridges that span rivers and other bodies of water. This tool is primarily intended to inform regional highway prioritization for emergency response activities; however, the BSST provides a useful evaluation methodology that could be applied to other regional emergency preparedness and infrastructure assessment studies. This could include studies of bridge infrastructure to other potential seismic events within the region, or at varying jurisdictional levels (i.e., county, local). The BSST also uses currently available seismic, seismically-induced secondary hazard and infrastructure information. As new seismic information becomes available, or as secondary-hazards (e.g., landslides, avalanches) become characterized more comprehensively, such information could be integrated into the current BSST methodology. Similarly, as seismic retrofit activities or other infrastructure improvement projects continue throughout Washington State, or as new infrastructure are built, it will be important that the infrastructure data integrated in the BSST also be updated periodically. Doing so will ensure that planners and infrastructure managers maintain the most current and complete understanding of the network-level seismic risks of a CSZ event to Washington State highways.Please note that all results from the BSST are based on a model and information received from WSDOT. Damages from an earthquake may be different that what is provided here. Liquefaction data was used within the BSST tool. WADNR is the source for liquefaction data and is available here: https://www.dnr.wa.gov/programs-and-services/geology/geologic-hazards/geologic-hazard-maps#nehrp-site-class-and-liquefaction-susceptibilityUSGS ShakeMap was also used in the BSST tool for a M9.0 Cascadia earthquake and is available here: https://earthquake.usgs.gov/scenarios/eventpage/gllegacycasc9p0expanded_se/shakemap/pga. DHS distributed this data to WSDOT on August 22, 2019.

The BSST was created for the Washington State Transportation RRAP which analyzed state highway and roads and their impacts from a Cascadia 9.0M earthquake. The RRAP report is available here: https://mil.wa.gov/asset/5d8ba2a03a1b7. The state bridge results in GIS format are available here: https://www.wsdot.wa.gov/mapsdata/geodatacatalog/default.htm . Technical and user manuals for the BSST tool are available here: https://www.osti.gov/biblio/1581518-washington-state-highway-bridge-seismic-screening-tool-bsst-technical-report In addition to the state bridges that were analyzed above, local bridges were obtained from WSDOT and analyzed in the BSST which is the data that is presented here. The data was provided from WSDOT to CISA Region 10. Much of the data for local (city/county) bridges were taken from the national bridge inventory and additional data that WSDOT had available. The local data used in the BSST is not complete and should be updated at the local level by bridge engineers and GIS specialist and analyzed in the BSST to ensure the latest bridge information is included in the tool. The data provided here is an initial analysis using data from WSDOT but it is recommend that local jurisdictions update their information and re-run the tool to ensure the most accurate data is used. The data provided here only includes bridges in western/central WA and only for a Cascadia 9.0M event. The 4,306 local highway bridges incorporated into this study from the WSDOT bridge inventory database were assessed using the BSST analysis methodology detailed previously in this report. Results consist of three types of outcomes: Bridge Damage Levels and Types, Bridge Repair Types, and Bridge Reopening Times. All output is a part of this feature class. Bridge damage types are projected on the basis of both damage level (None, Moderate, Significant), whether a bridge is a special bridge type, and also the types of damage that the bridge will experience (including both direct seismic and secondary earthquake-induced impacts); The projected repair types and reopening times necessary to bring bridges back to a minimum level of functionality that enables their use for emergency response were computed using the methodology specified in the Bridge Reopening Times section. Refer to the BSST Technical Report. The BSST was developed to assess the potential impacts of a CSZ earthquake to highway bridges in Washington State at a system-level as part of the Washington State Transportation Systems RRAP project. The results provided identify the Damage Levels, Damage Types, Repair Types and Reopening Times associated with 4,306 bridges located in Western and Central Washington that were evaluated for this RRAP project. Understanding that this analysis likely constitutes a “worst-case scenario” with respect to bridge damage, the results nonetheless project that the majority of bridges in Washington State will experience moderate to significant damage resulting from a CSZ earthquake. While the majority of bridges that experience damage could be reopened within one year of the earthquake, a substantial number of those bridges are projected to take more than a year to reopen—in many cases 2 or more years. The results also project that while many bridges may be reopened after either minor repairs/inspections or the construction of a temporary bypass road, a substantial number of more significantly damaged bridges span bodies of water and will require complete replacement prior to reopening. This suggests that significant gains in roadway corridor reopening times could be gained by focusing on retrofits or upgrades to these more vulnerable bridges that span rivers and other bodies of water. This tool is primarily intended to inform regional highway prioritization for emergency response activities; however, the BSST provides a useful evaluation methodology that could be applied to other regional emergency preparedness and infrastructure assessment studies. This could include studies of bridge infrastructure to other potential seismic events within the region, or at varying jurisdictional levels (i.e., county, local). The BSST also uses currently available seismic, seismically-induced secondary hazard and infrastructure information. As new seismic information becomes available, or as secondary-hazards (e.g., landslides, avalanches) become characterized more comprehensively, such information could be integrated into the current BSST methodology. Similarly, as seismic retrofit activities or other infrastructure improvement projects continue throughout Washington State, or as new infrastructure are built, it will be important that the infrastructure data integrated in the BSST also be updated periodically. Doing so will ensure that planners and infrastructure managers maintain the most current and complete understanding of the network-level seismic risks of a CSZ event to bridges in Washington. Please note that all results from the BSST are based on a model and information received from WSDOT. Damages from an earthquake may be different than what is provided here. Liquefaction data was used within the BSST tool. WADNR is the source for liquefaction data and is available here: https://www.dnr.wa.gov/programs-and-services/geology/geologic-hazards/geologic-hazard-maps#nehrp-site-class-and-liquefaction-susceptibilityUSGS ShakeMap was also used in the BSST tool for a M9.0 Cascadia earthquake and is available here: https://earthquake.usgs.gov/scenarios/eventpage/gllegacycasc9p0expanded_se/shakemap/pga. Data Assumptions/MethodologyData was provided by WSDOT for all local bridges. Data was transferred into BSST format. Bridges that were not included in the Cascadia 9.0M ShakeMap were removed from the tool. This mainly encompasses bridges in the far eastern side of the state. Removed all bridges that were designated as a pedestrian, trail or dam. Removed all bridges that had null or 0 structure length. Those bridges that had no main span quantity, all were changed to 1, meaning a single span bridge. For the bridges missing the federal functional class a value of 9 was assigned. For the bridges with a null in waterway adequacy these values were changed to N. For those bridges that had a null value for scour code these were change to N. Some points had low accuracy coordinates (lat/longs), so these locations were removed from the database since they could not be found. For those bridges that had a BMS elements ID related to a Pier Wall a W code was added to the Pier Type in the road bridges spreadsheet of the BSST tool. This would ensure these bridges were counted as having a pier wall. This information should be updated and verified by local jurisdictions. Snohomish County used the tool for their local bridges. A few of the bridges output in this tool was updated to reflect their results since better data was provided by the county. The tool uses AASHTO curves from various years. These curves were digitized in GIS from a pdf map. The accuracy of these maps could be up to +/- 10 miles due to digitizing the data at the state level. Most of the offset occurred in eastern WA, so impacts should be minimal.

In 2007, Washington State legislators requested a trails database, but funding to complete that statewide project was not made available at the time. In 2009, the Federal Government outlined the need for trails database schema in their Data Standards Review Committee, stressing the efficiency in management decisions that a streamlined database can provide. “The collection, storage and management of trail related data are important components of everyday business activities in many federal and state land-managing agencies, trail organizations and businesses. From a management perspective, trails data must often mesh closely with other types of infrastructure, resource and facility enterprise data.” In 2014, the Washington State Office of the Chief Information Officer's (OCIO) Geospatial Program Office acquired a Nonhighway and Off-Road Vehicle Activities (NOVA) Program grant through the Washington State Recreation and Conservation Office (RCO) giving the OCIO initial funding to develop a statewide trails database based on Federal Geographic Data Committee standards. Using the same standard for all trails data will allow land managers and recreational users throughout the state to access and use the data regardless of administrative boundary. "Data standards will make it easier for trail information to be accessed and exchanged and used by more than one individual agency or group…Ease in sharing data increases the capability for enhanced and consistent mapping, inventory, monitoring, conditions assessment, maintenance, costing, budgeting, information retrieval, and summary reporting for internal and external needs.” Along with streamlining data and facilitating efficiency in management practices across agencies, the database will provide a source of trails information that is open and free to the public.The 2016 State Legislature provided additional funding from the Nonhighway and Off-road Vehicle Activities Account to the Office of the Chief Information Officer to continue work on the database.
