Central San and the Local
Government Information Model
Laying the Foundation for a GIS-Centric
Wastewater Agency
Carl Von Stetten
GIS Analyst
Central Contra Costa Sanitary District(aka Central San or CCCSD)
• Serve the central portion of Contra Costa county in California (35 minutes east of San Francisco)
• Wastewater collection and treatment for 327,000 residents and business customers
• Wastewater treatment for 134,000 residents of the cities of Concord and Clayton
• Household hazardous waste collection for all residents in central Contra Costa County
• Treat average of 30 MGD (up to 53 MGD in wet weather)
First, a little bit of history…
Central San GIS - BC*
*(Before Computers)
Central San GIS 1996-2006
• Produce paper maps more efficiently
• MicroStation + MGE
• Intergraph CLIX workstations, then PCs
with Windows NT 3.51
• Custom data model
• Reliability issues
• Frequent MicroStation
file corruption
Central San GIS 1996-2006
• Started thinking about web maps in
1999
• Implemented first web GIS ~2002
• Autodesk MapGuide + Allaire ColdFusion
• Creative solutions to linking to other
systems/databases
• Problems reliably converting MGE tiled
data into seamless MapGuide files
Central San GIS 2005-2006
• Moved to Intergraph GeoMedia ‘05-’06
• Developed custom data model
• Designed to balance needs of paper map production with web map accessibility
• Better connectivity with other systems, especially Sussex (Accela) CMMS
• Hired Intergraph to write custom code to automate tasks and build the linkages to CMMS and other systems
Central San GIS 2005-2006
• Rewrote entire MapGuide/ColdFusion
web GIS to work with new data model
• Used Safe Software’s FME to translate
between GIS and database formats
Central San GIS 2006-2016
The level of integration we
wanted…
…what we actually ended up with.

Central San GIS 2006-2016
• Realization we were maintaining two diverging inventories (GIS & CMMS)
• Both inventories tracked similar attribute data
• Inventories don’t match• >6% records don’t have matching IDs
• Significantly larger number of records with attribute differences
• Connecting to other business systems was similarly hard
A Fresh Start
• Replace our GIS (GeoMedia + MapGuide)
AND our CMMS (Sussex/Accela)
• Implement a sustainable desktop/web GIS
platform
• Implement a GIS-centric CMMS
• GIS would be inventory authority of record
Other Systems Requiring GIS
Integration
• Planning & Applied Research Group
• Innovyze InfoWorks ICM SE for dynamic hydraulic modeling
• Innovyze InfoMaster for asset integrity management and capital
planning
• Collection System Operations Division
• WinCan / Granite XP / IT Pipes(??) for CCTV inspection
• Plan Review/Permits/Inspection Groups
• Sungard (HTE) for permits, sewer billing, and parcel
ownership/tax roll managment
Central San GIS Ecosystem
Choosing the Platforms
• Esri ArcGIS Desktop / Server / Portal
• Integrated solutions from single vendor
• Azteca Cityworks AMS
• Tight integration with ArcGIS Server
• Features met needs of our Collection System
Operations division
• Management decided to convert our Plant CMMS
to Cityworks too to consolidate asset management
Getting the Help We Needed
• Signed an EEAP contract with Esri in
March 2013, renewed once
• Signed 3-year ELA with Esri in November
2014
• Issued RFP for CMMS implementation/
migration services
• Awarded contract to Woolpert
Let’s Design Another Data Model From
Scratch (uh… no)
• As part of EEAP, Esri staff started to
assemble a custom data model from
previous customer implementations
• Central San GIS staff started looking at
the Local Government Information Model
(LGIM)
• Decided the LGIM was a good fit for our
organization
LGIM Advantages
• Supported by many
Esri partners
• Sets an industry
standard
• Improves data
interoperability/ sharing
• Provides structured
framework for data
model consistency
• Out-of-the-box maps
and applications for
both desktop and web
• Attribute Assistant
automates many tasks
• Support for parcel
fabrics/ geometric
networks
• Use as much/as little as
you need
LGIM Example
Feature Datasets Feature Classes
Planning the Migration
Automating the Data Migration
• Split workload of developing ETL
processes for various data sets with Esri
• Developed FME ETL processes for
everything except parcel fabric
• Esri tools for parcel data import
Example FME ETL Process
ETL for SewerStormwater Feature Dataset
Planning the Infrastructure
• All GIS servers are virtualized
• (Microsoft Windows on VMware vSphere)
• GIS group controls our own VMware cluster
• Freedom to deploy virtual machines as needed
• Separate testing/production environments
• SQL Server enterprise Geodatabases
• ArcGIS servers
• Dedicated ArcGIS server for Cityworks map
services

Web GIS – A Change In Plans
• Originally planned to build web maps/apps
using Esri tools
• Portal for ArcGIS Server / ArcGIS Online
• Web App Builder or JavaScript API
• Compressed schedule called for a
different approach
Geocortex Essentials
• Provides a web map application interface in front
of ArcGIS Server map/feature services
• >80% of the user interface (UI) features we
needed were available in the product
• No custom code – just configuration through web
administrator UI
• Fantastic global search, including geocoder results
• Responsive design for desktop/mobile/phone
• HTML5/JavaScript viewer works with all modern
browsers, no plugins required

Wrap Up…
• The LGIM provided an industry-standard
framework with many supporting maps
and tools
• We customized the LGIM to meet our
specific needs
