Description: This dataset is for displaying Freeway Buffers at 150ft, 300ft and 600ft in Snohomish County. Only Interstate 5 and 405 and State Routes 522, 525 and 526 are used. This dataset was derived using the County Features Streets 911 dataset:This dataset represents road centerlines (RCLs) for all named streets (including those named with a number) and private driveways in Snohomish County for use in the Washington State Next Generation 911 (NG911) program to support emergency call routing. RCLs follow the NENA RCL GIS data model and are provided to the Washington State NG911 program on a monthly basis and to Snohomish County Public Safety Answering Points on request. Any other use of these data are not directly supported by Snohomish County.Roads and driveways are updated daily or weekly from addressing notifications sent from partner jurisdictions, Snohomish County PDS, SNO911 dispatcher comments, reports from field crews, UAS flights conducted by EESCS, and other verified data sources as required. Named roads are typically digitized from official site plans and occasionally deviate from final construction. Private driveways are added to support proper routing of emergency crews and often include unofficial or ad-hoc roadways, and will always join another RCL at a vertex. Named roads are split wherever they intersect another named road or cross a jurisdictional boundary. Fields include valid TO and FROM address ranges for the street segment. In some cases, RCLs in new developments may appear in data before the roadway is completed. For a detailed description of all fields please refer to the NENA NG911 data model: https://www.nena.org/page/ng911gisdatamodel
