Lineage Add
01/01/1988	Acquired street linework and annotation from Oregon Department of Transportation. This was digitized from 7 1/2 minutes USGS quad sheets.
01/01/1991	Replaced linework with newly digitized line work which "fell within" the street rights-of-way from the tax lot layer. Attributes were transfered from the U.S. Census Bureau TIGER file. Street names and address ranges were updated using paper maps collected from the three counties. Thomas Brothers Mapping was the primary contractor.
01/01/1991	The dataset was originally created by modifying the 1990 TIGER Census Centerline dataset to match the Oregon Department of Transporation (ODOT) maps.
04/01/1998	We deleted types 1600, 1900, 2100, 2200, 3100, 3210, 3220. Streets are no longer shown on the Clark County side of the river. Contact Clark County for detailed street information.
07/01/1998	This layer was reprojected to the NAD83/91 projection (also known as HPGN) as part of a conversion of all RLIS map layers.
07/15/2001	Projection information (.prj file), compatible with ArcGIS 8.1, was added to the layer.
10/31/2001	Add XML metadata compatible with ArcCatalog 8.1
10/31/2002	QC street name, addresse, city and zipcodes using E-911 CAD materials for Clackamas County (complete 20020901) and Washington County (complete 20021031).
10/24/2003	Hillsboro streets positional accuracy was improved. Streets were snapped to local planimetric data with a +/- 1' tolerance. The City of Hillsboro now maintains their subarea and supplies the data to Metro on a weekly basis.
01/01/2004	The City of Portland receives updates of the Regional Street Network on a quarterly basis. These updates are written to the regional dataset to update the segments that are not maitained by the City of Portland.
04/07/2020	The City of Portland maintains and updates the segments in and around the City of Portland (there is approximately a 1mi buffer around the City of Portland that is maintained by the City) on a weekly basis.
