This feature class is made up of City of Austin zoning ordinance boundaries. Work on this layer began in 2001 with zoning ordinance polygons entered on a day forward basis. Therefore, polygons for older ordinances are less likely to be included in this data.

This layer represents contour elevation lines as of the spring of 2017. The contours are derived from LiDAR data, collected in the winter of 2017/2018. Contours were generated using Global Mapper, sample spacing used to create the contours is consistent with the Nominal Point Spacing (NPS), of the source LiDAR dataset from which it was derived. Lines were automatically smoothed while being generated by Global Mapper.

Core Transit Corridors identified in the May 12, 2005 City Council Approved Design Standards Policy Document, with recommended amendments made August 4, 2006.
