Data Set Description: Community Development Districts were created by the Office of Planning and Building during their planning sessions for revitalizing Oakland's various communities.

Non-standard Attributes in table:

• U_ID: Provides the user with a unique indentifying number for each polygon in the layer.
• COMMDEV_DIST: Name of Community Development District.

Data Source History: ESRI originally digitized the Commdev layer in UTM projection, NAD27. Jonathan Lowe (LKC) converted it into Cal Stateplane, NAD83, units feet, using Arc/Info's projection utility and two custom AML's called "utm2spc.aml" and "nad2783.aml." Upon the adoption of the "streets" coverage and the digital orthophoto as Oakland's standard for coordinate accuracy, the commdev coverage was corrected using the arc/info "adjust" command with parameters based upon the node-to-node links established during the tiger-roads conflation process. Further manual adjustment of this layer to match orthophoto accuracy is still outstanding.

Quality Check: No quality control procedures have yet been performed on this layer outside of OCIS.
