WSDOT - Stormwater Debris Rack - Field

This is a view of the DebrisRack featureclass created with the following query: LifeCycleCurrentStatus= 'Active' AND (WSDOTownership in ('Yes', 'Unknown') OR WSDOTownership IS NULL) AND SWLocationVerified = 'Yes' This feature class contains WSDOT’s stormwater debris racks. A debris rack is a structural device such as grates or rods used to prevent debris from entering a drainage structure, and can include a barred culvert end if the bars are intended to keep debris from entering the pipe. Additional terms used to describe this type of structural device are“trash rack” or “bee hive”. The majority of the data collected so far are within the Phase I and Phase II 2009 NPDES Municipal Stormwater Permit Areas.

本数据集为通过以下查询语句生成的DebrisRack要素类（featureclass）视图：生命周期当前状态（LifeCycleCurrentStatus）='有效' 且（WSDOT所有权（WSDOTownership）为'是'、'未知'或为空值） 且 雨水位置验证状态（SWLocationVerified）='是'。该要素类包含WSDOT所辖的雨水拦污栅数据。拦污栅是一类用于阻挡杂物进入排水构筑物的结构性设施，形式包括格栅或杆栏结构；若涵管端部加装栏栅以阻挡杂物进入管道，则该带栏涵管端部也可归入此类。该类结构性设施的其他通用称谓包括"垃圾拦栅（trash rack）"与"蜂箱式拦栅（bee hive）"。截至目前，所收集的绝大多数数据均位于2009年国家污染物排放消除系统（NPDES）城市雨水许可的第一阶段与第二阶段覆盖区域内。
