Data Set Description: Fire battalions divide the City into sub-areas that are a basis for resource assignment in emergencies requiring a larger response than one engine company or one still district.

Non-standard Attributes in table:

• U_ID: Provides the user with a unique indentfying number for each polygon in the layer.
• CITY_NAME: A battalion number defined by the Oakland Fire Department

Data Source History: Capt. Mike Kelly, OFD, delivered a AAA paper map (1980, scale 1" = 2640') with battalion boundaries highlighted with a flourescent hi-lighter marker. The battalion boundaries followed street centerlines and/or city limit lines. Jonathan Lowe (LKC) scanned and registered the paper map to the existing center of pavement GIS layer using ArcInfo's register and rectify commands. Jonathan then digitized the battalion lines using the heads-up technique of on-screen digitizing.

Quality Check: Julia Howlett, JRH Consulting, corrected the accuracy of the battalion lines when the overall accuracy levels of the Oakland GIS layers improved.

Security restrictions: No security restrictions.
