Description
  Abstract: Contains features representing road edges, sidewalks, alleys, 100 foot driveways, parking lots, bridges, medians, buildings, and various pathways. All features were originally derived from the City's first delivery of planimetric data in 2000, as interpreted from 1999 orthophotography. These features do not necessarily correspond to units that are suitable for analysis. The initial delivery contained a continuous polygon source, which was later separated into three feature classes to optimize query and display performance. The contents have been maintained here since 2000 by Public Works and Community Development using site plans and other sources received during development review processes.
  Purpose: To be used for cartographic display of basic improvement infrastructure.
