Combination of stream centerlines created from aerial orthophotography, planimetrics based on LIDAR data "Hydro_L" (a non continuous stream) and construction plans which has been updated and edited to be a continuous stream. Creeks_line_mains is the maintenance version of this layer.

One item in the "Fea_Code" attribute domain has been renamed from "Concrete lined open channel" to "altered channel" and an additional domain descriptor has been added called "Altered channel (roadside)". The "Comments" field is used to further define an altered channel's sub-type as "Concrete lined". Features previously labeled as concrete lined in the "Fea-Code" field are identified as such in the "Comments" field. Identifying altered channels (roadsides) will be on an ongoing basis.
