1. Development of a Public Notifications Tool using Python
Nicola Morais – EnerGov Applications System Specialist
City Of San Luis Obispo

2. The Request
Need lists of Owners and Occupants within a distance of a new development or permit (in excel format).
Need a map of the area and parcels notified (pdf).
Must capture parcels containing multiple ownership e.g. Condos.
Need a repeatable methodology which is easy for new planning interns to complete with minimal GIS training.

3. Setting up the map Group parcels Symbolized Layers
Create Folders and GDB

4. Python Script Parameters Spatial Query's Table Adjustments
User Selects Parcel to be Buffered, opens tool and fills out parameters.
ProjectName = arcpy.GetParameterAsText(0)
BufferDistance = arcpy.GetParameterAsText(1)
OutputDirectory = arcpy.GetParameterAsText(2)
arcpy.Buffer_analysis
arcpy.SelectLayerByLocation_management
Parcel Groups
All Parcels (add to selection for Owners).
All Addresses (add to selection for Occupants).
arcpy.CopyFeatures_management (Create map Layers).
arcpy.TableToTable_conversion (Create Table)
Using arcpy.env.overwriteOutput = 1 to allow overwrite
Table Adjustments
Map Adjustments
arcpy.DeleteIdentical_management
arcpy.DeleteField_management
arcpy.TableToExcel_conversion
Completed for both Owners and Occupants Tables
arcpy.mapping.MapDocument
arcpy.SelectLayerByAttribute_management
arcpy.RefreshActiveView()
arcpy.mapping.ExportToPDF
Creates PDF Map of Notifications Layers Zoomed to the extent of the notified Parcels

5. Result Owners Excel list Occupant Excel list PDF Map Next Step
We then adapted the script to take a fourth Parameter: a shapefile to buffer instead of selecting a parcel. This tool can be used for Event Notifications.

6. Automation of Map Book Updates Python

7. The Mission
Automate updates to pdf map book pages (aka data drive pages)
Capture - Utility staff updates (cityworks)
- pipe type, pipe size etc.
Export only a subset of pages- those with features

9. Python Script

10. Automate the Script with Task Scheduler
