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


• 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


• 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


• Rewrote entire MapGuide/ColdFusion

web GIS to work with new data model

• Used Safe Software’s FME to translate

between GIS and database formats


The level of integration we

wanted…

…what we actually ended up with.

• 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
