Central San and the Local Government Information Model

Laying the Foundation for a GIS-Centric Wastewater Agency

Carl Von StettenGIS Analyst@cfvonner

Central Contra Costa Sanitary District(aka Central San or CCCSD)

Central San Fun Facts• 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)• 1,500 miles of collection system pipelines

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 MicroStationfile corruption

Central San GIS 1996-2006• Started thinking about web maps in

1999• Implemented 1st production web maps

~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 2006-2016The level of integration we wanted…

…what we actually ended up with.

Central San GIS 2006-2016• Realization that maintaining two diverging

inventories (GIS & CMMS) was our Achilles heel• 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 servers for Cityworks map

services

ArcGIS Infrastructure – Initial Plan

MS SQL Server 2012Standard Edition

“Default” Instance = Production“TESTING” Instance = Testing/Training

Esri ArcGIS Server 10.3Image services

(tile caches)

Esri ArcGIS Server 10.3Production map services

for web apps

Esri ArcGIS Server 10.3Production map services

for Cityworks AMS

MS SQL Server 2012Developer Edition

Runs on each Analyst’s workstationfor Geodatabase development

Esri ArcGIS Server 10.3Map service

development/testing

Portal for ArcGIS Server 10.3 GIS Services Gateway

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 (Flash/Silverlight) required
