Description
Abstract
Humboldt County Highways and Roads, December 2010. This GIS dataset is the result of ongoing efforts to produce an accurate Roadway Centerline GIS layer for Humboldt County. Multiple source datasets were merged and edited to create this master roads layer. This centerline data consists of all public and some private roads in Humboldt County. Location geometry is based on 2005 Airphotos - USDA NAIP County Mosaic. Address ranges, City and Zip attributes have been checked and corrected using various sources including parcel site addresses. Roadway Functional Class is based on Humboldt County Travel Demand Forecasting Model.
Purpose
To be used as a general guide to Highways and Roads for Humboldt County for street and address location.
Supplementary Information
June 2008 - Added County General Plan Functional Classification attribute and values - [planfunc]
December 2010 - Validated topology and verified road names and State Road name with 2010 Humboldt County Public Works Road Log. (mlawler)
