WSDOT - Sensitive Aquatic Areas

This feature class contains environmentally sensitive areas that front state highways, including wetlands, waterbodies, streams, and channel migration zones. Roadway segments within 300 feet of a sensitive area were located using GPS. The sensitive areas are represented by lines segments which have had their beginning and ending points buffered an additional 300 feet. Data has been synchronized to the LRS December, 31 2017.本要素类（feature class）包含临州级公路的环境敏感区域，涵盖湿地、水体、溪流及河道迁移带。通过全球定位系统（GPS）定位了与敏感区域间距不超过300英尺的道路路段。上述敏感区域以线段形式表示，且其起止点额外增设了300英尺的缓冲区。本数据已于2017年12月31日与线路参照系统（Linear Referencing System，LRS）完成同步。
