Known Issues


There is no GIS data for geodetic control points, so parcels areconstantly being adjusted.

Not all data has a GIS polygon.

Polygons are only indexed by the first page, so a search for thesecond page will not have a result.

Each page is in a single PDF file, so there is no easy navigation between pages.

There is no online database that would allow an integrated search of all projects.

From the tabular index, there is no way to zoom to that feature in the interactive map.

Recorded and Filed Map Process


Create index point/polygon in GIS shapefileRecorded Map Methodology: Older recorded maps are constructed inCAD using distance and bearings. Subdivision maps are are constructed from the parcel layer. Records of Surveys also include slivers to nearby monuments, but not distant CORS.



Create index point/polygon in GIS shapefileCorner Record Methodology: Only controlling monuments are depicted. Reference monuments set to perpetuate existing monuments are not depicted.

Known Issues

Hard to find documentation or recordation information for older actions, especially some of the ones from the 1800s.

Recent actions are recorded, so the recorded documents are only available to the public at the County Recorder’s Office.

Not all actions have been scanned.

Reviewing the accuracy of the index polygons takes time.
