DWW Proposed Water Quality Points

This grouped layer uses data from DWW.WQS_PV(point features) and DWW.polygon_plgn_pv(polygon features). To display the polygons the following query is used, PLY_LIFECYCLE_CODE in ( 'C', 'PC', 'UNK', 'T', 'TBC', 'U') and PLY_DWW_FEATYPE_CODE = 'WQS'. Labels are based on the attribute DESCRIPTION. The point features uses this query, WQS_PV_LIFECYCLE_CODE in ('C', 'PC', 'UNK', 'T', 'TBC', 'U'). Labels are based on the attributes WQS_PV_FEA_TYPE and WQS_PV_FEATYPE_DESC. Included are layers for the Proposed assets, and separately the Abandoned/Removed assets. The features and associated labels do not display when zoomed out beyond 1:10,000. Maintained by SPU GIS DWW Data Maintenance staff.
