This dataset represents the location of site structure address points (SSAPs) for officially and unofficially addressed buildings and similar structures in Snohomish County that could be reported to 911 for the purpose of emergency call routing.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset represents the location of site structure address points (SSAPs) for officially and unofficially addressed buildings and similar structures in Snohomish County for use in the Washington State Next Generation 911 Program that could be reported to 911 for the purpose of emergency call routing. SSAPs 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.</SPAN></P><P><SPAN>These data are updated weekly from address notifications sent from partner jurisdictions, Snohomish County PDS, reports from field crews, SNO911 dispatcher comments, UAS flights conducted by EESCS and other verified data sources. SSAPs are typically placed over the center of a building but may be moved closer to an adjacent road centerline as needed for proper routing of emergency crews. SSAPs were originally generated via parcel centroids and unless moved remain there. New SSAPs are placed according to approved site plans and may occasionally differ from final physical placement. For addresses containing multiple sub-addresses (EX two units or apartments sharing a common address), a point is created for each sub-address AND a separate point containing no sub address information. </SPAN></P><P><SPAN>Examples of unofficially addressed locations include legacy addresses that may still be commonly reported by 911 callers, temporary construction sites, unapproved ADUs, or similar temporary housing or shelter with self-reported addressing. Such SSAPs are included in these data for the express purpose of routing emergency services to the reported location, regardless of true address. As such, SSAPs will periodically contain erroneous data by design. In some cases, SSAPs in new developments may appear in data before the roadway is completed. </SPAN></P><P><SPAN>For a detailed description of all fields please refer to the NENA NG911 data model: https://www.nena.org/page/ng911gisdatamodel </SPAN></P></DIV></DIV></DIV>
