A geographic representation of the municipal boundaries updated by SanGIS when notified by LAFCO of a recorded annexation or detachment. The revised layer is published as needed once changes are made and verified. Adjustments are also made to this dataset from ongoing landbase maintenance activities.
SanGIS will add individual polygons for annexations to a municipal jurisdiction but will not maintain a separate polygon for the agency losing territory. That is, a polygon will be created for the "gain" but the "loss" will be reflected only by modifying the existing boundary.
On an annual basis, SanGIS will reconcile the JUR_MUNICIPAL layer with the JUR_MUNICIPAL_ASR layer developed by the Assessor. This will happen when the Assessor publishes the annual TRA updates. SanGIS will accept the Assessor layer as is and use it as the basis for new annexations/detachments going forward. Individual polygons that have been created in the past year will be incorporated into the municipal boundary as shown on the Assessor's TRA updates.
NOTE: The County Assessor's Office JUR_MUNICIPAL_ASR layer is the official Municipal Boundary layer; however, it is created for tax purposes and is only updated on an annual basis as required by state law.
