National Inventory of DamsThis feature layer, utilizing National Geospatial Data Asset (NGDA) data from the U.S. Army Corps of Engineers (USACE), displays dams within the United States, Puerto Rico and Guam. Per the USACE, "The National Inventory of Dams (NID) consists of dams meeting at least one of the following criteria:High hazard potential classification - loss of human life is likely if the dam fails.Significant hazard potential classification - no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns.Equal or exceed 25 feet in height and exceed 15 acre-feet in storage.Equal or exceed 50 acre-feet storage and exceed 6 feet in height".The goal of the NID is to include all dams in the United States that meet these criteria. In most cases, dams within the NID criteria are regulated (construction permit, inspection, and/or enforcement) by federal or state agencies, who have basic information on the dams within their jurisdiction."Hoover, Davis & Glen Canyon DamsData currency: This cached Esri federal service is checked weekly for updates from its enterprise federal source (NID2019 U) and will support mapping, analysis, data exports and OGC API – Feature access.Data.gov: Not AvailableGeoplatform: Not AvailableOGC API Features Link: (National Inventory of Dams - OGC Features) copy this link to embed it in OGC Compliant viewersFor more information, please visit: National Inventory of DamsFor feedback please contact: Esri_US_Federal_Data@esri.comNGDA Data SetThis data set is part of the NGDA Water - Inland Theme Community. Per the Federal Geospatial Data Committee (FGDC), Water - Inland is defined as the "interior hydrologic features and characteristics, including classification, measurements, location, and extent. Includes aquifers, watersheds, wetlands, navigation, water quality, water quantity, and groundwater information."For other NGDA Content: Esri Federal Datasets

Welcome to Washington state's Freight Transportation System map application! Detailed descriptions are provided below. To get started, press the View Application button in the upper-right corner of this page. Once open, please read the brief instruction provided. This web map application provides an interactive GIS tool for users to view Washington state's freight transportation system by types and modes. It reflects WSDOT's 2021 Freight and Goods Transportation System update, and the National Highway Freight Network designations verified and published by FHWA as of 2019. This web map application was intended to provide valuable freight data sources to support transportation planning efforts, and includes the following sublayers:   1. Freight Intermodal Facilities - shows major freight intermodal facilities in Washington state, including cargo airports, rail intermodal terminals, and major ports handling freight shipments.2. 2021 Freight and Goods Transportation System (FGTS) – classifies freight corridors by modes in Washington State based on annual freight tonnage moved, including truck, rail, and waterway freight corridors. Each modal network is classified into five tiers and the specific annual tonnage thresholds are described below. 1) FGTS truck corridors include: T-1 corridors: more than  10 million tons T-2 corridors: 4 million to 10 million tons T-3 corridors: 300,000 to 4 million tons T-4 corridors: 100,000 to 300,000 tons T-5 corridors: at least 20,000 tons in 60 days and less than 100,000 tons per year 2) FGTS rail corridors include: R-1 corridors: more than 5 million tons R-2 corridors: 1 million to 5 million tons R-3 corridors: 500,000 to 1 million tons R-4 corridors: 100,000 to 500,000 tons R-5 corridors: Less than 100,000 tons 3) FGTS waterway corridors include:   W-1 corridors: more than 25 million tons W-2 corridors: 10 million to 25 million tons W-3 corridors: 5 million to 10 million tons W-4 corridors: 2.5 million to 5 million tons W-5 corridors: 0.9 million to 2.5 million tons 3. Truck Freight Economic Corridors - 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. It includes following components: High volume truck corridors: T-1 and T-2 freight corridors; Alternative freight routes: routes that serve as alternatives to primary cross-state freight routes during severe weather or other disruptions; 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. 4. National Highway Freight Network – established under the Fixing America's Surface Transportation Act (FAST Act) consisting of four components: Primary Highway Freight System (PHFS) Other Interstate portions not on the PHFS Critical Rural Freight Corridors (CRFCs) Critical Urban Freight Corridors (CUFCs) 5. Manufacturing and warehousing land use (2020 parcel data) - shows parcels with manufacturing and warehousing land use codes from 2020 statewide parcel database: https://wsdot.maps.arcgis.com/home/item.html?id=3dca0b72eae94c098b21329e1e61afd76. Jurisdictional Boundaries - include Regional Transportation Planning Organization, County Boundaries, and City Limits.For more information about FGTS system, please visit https://www.wsdot.wa.gov/freight/fgts.

Polygons representing natural waterway or channel structure locations (such as sediment ponds, litter traps, weirs, spillways, drop structures) and associated details. Includes description, asset section (for As Constructed drawings) and key attributes. This layer is intended to help identify the location of Melbourne Water's drainage assets for asset management and maintenance purposes.Waterway (Reach) layer created from original FIS 1:50K (Vicmap Hydro) streams data set which included only those waterways within catchments of greater than 60ha. Waterways (Reach) Rectification project undertaken 2001 to 2003 to review and correct the extent of the waterways reach network to ensure a complete data set exists (using the Drainage Metropolis Boundary, 50K data, 1:2500 Drainage Record Plans, Drainage Limits data, orthophotos, as constructed and/or design drawings, contour data and Melway Street Directory). Waterway (Reach) extents defined and attributes populated in GIS and Hansen (AMIS) for all records including assigning nodes and node numbers (for start / end points) and removing any reaches less than 100 metres in length that are predominantly channel assets. Waterways in extended area incorporated in 2005 using Vicmap Hydro data and aerial imagery, then updated in 2009/10 using Lidar survey data (contours). Data is maintained using Lidar survey data (contours) and 60 ha limits. Please refer to metadata for each record in dataset for specific source / accuracy information.NOTE: Whilst every effort has been taken in collecting, validating and providing the attached data, Melbourne Water Corporation makes no representations or guarantees as to the accuracy or completeness of this data.
