SBE Audits

SBE is responsible for the proper voter placement within statewide jurisdictions, but not the creation of those jurisdictions.

SBE conducts an electronic audit every weekend and makes those results available on every Monday morning for use by CBE election officials.

SBE Audits

What is an SBE jurisdictional audit?An SBE jurisdictional audit consists of the

following steps:

1) SBE imports all voter addresses into SBE GIS system.

2) SBE maintains all voter addresses in separate database.

3) Audit is performed in SQL Server database using stored procedures.

4) Stored procedure uses SQL ‘STIntersects’ and several joins to overlay addresses, jurisdictions to identify mismatches.

5) Exceptions such as voters not in the correct jurisdiction and addresses not found are identified for the county in shapefiles, dbf and kmz file formats.

CBEs will utilize the SEIMS Geocode application to make updates to correct street ranges in the incorrect jurisdictions. Counties can use the assistance of their county GIS or Mapping Department.

Just because you have a number greater than Zero in the Audit may not mean there is an issue. The following can be reasons for audits showing voters in the incorrect jurisdiction:

1. Some addresses may not plot exactly on a map, especially in rural areas. Ever put an address in your GPS and ended up somewhere else?

2. Addresses for college, military and apartment complexes sometime yield incorrect points on the map.

3. Incorrect street ranges in Geocode

4. Counties using incorrect addressing standards from the voter application.

So how can we get better results?

1. Currently we have around 51 of the county E911 addressing files. We are currently working with all counties to receive all county E911 files which will help with better addressing points on the map.

2. Counties should send the NOGEOPTS file to their county GIS department. The GIS department can then locate the correct address point for our system and send it back to us so that we may update our master address database.

3. Soon, counties will have the ability to correct their own address points in their audit if that point was incorrectly placed on the map by the state’s audit system.
