1 Converting Sewer and Stormwater assets to Esri s LGIM Why, how and what did the City of Portland, ME get out of it? Jessica Gooch Asset Management Technician City of Portland Maine, Water Resources Division

2 Why did the City do this? Utilize the ELA that the City has with Esri Leverage the LGIM and ArcGIS for Water Utilities tools Editing, Networking, App Development Standards, standards, standards Adhere to specific standards for both GIS and Sewer/Stormwater Utility standards Protocols, SOPs and procedures Establish editing workflows, procedures and protocols to ensure timely data collection and integration The City of Portland is an MS4 community (Municipal Separated Sewer System). The MS4 is a permit that we hold with the EPA concerning the separated stormwater system targeted to improve water quality by outreach, BMP s, daily maintenance operations (mapping, evaluating the system, street sweeping, catch basin cleaning etc.) and inspections and assessments. The City of Portland has a CMOM (Capacity, Management, Operations and Maintenance) plan that requires that the City have an Asset Management Plan for its sewer and stormwater assets. EPA Administrative order to have an asset management plan which includes knowing where all of our sewer and stormwater assets are located, what condition they are in and have the ability to manage these assets long term

3 What We Need to Manage: 107 miles of Sanitary Sewer Pipe 120 miles of Stormwater Pipe 120 miles of Combined Pipe 9 Wastewater Pump Stations 15,000 Storm and Sewer Manholes and Catch Basins 12 CSO Outfalls East End WWTF Shared-Responsibility

4 Asset Management Asset Information GIS City Works CCTV Hydraulic Model Risk Analysis COF LOF Risk Matrix Failure Model Maintenance Practices Renewal Plan Short Term Renewal Projects Cost Information Long Term Planning Budget

5 Asset Management Water Resources Division Portland, ME The City needs to be able to maintain a desired level of service for what our sewer and stormwater assets need are and then provide those services at the lowest cost. In order to be able to do this we need to answer 2 questions first!!! What does the City have for sewer and stormwater assets and where are they located? What condition are those assets in? We cannot really answer the second question without fully answering the first!!! Once we have the answers to those two questions then we can begin to really utilize asset management as a tool for planning. In order to get those two questions answered, the City needed a solution and a little help from our friends

6 What is the Solution??? Local Government Information Model and the Water Utility Network tools The LGIM is a Geodatabase Schema based on an information model of GIS datasets, web services and maps designed to help Local Governments implement an ESRI based solution for their GIS Data The Water Utility Network Editing Solution is designed for mapping technicians to manage water, sewer and stormwater network data What do you get? Attribute Assistant Add-in Water Utility Network Tools Local Government Geodatabase Local Government toolbox Water Utility Network Editing MXD Standard set of Sewer and Stormwater Symbology

7 The Process The City decided to enlist the help and expertise of the ESRI team in Redland s California to help us with the process of moving to the LGIM Review Design Migrate

8 Review Existing GIS Review Design Migrate GIS data is incomplete and has some inaccuracies No standard editing workflows or protocols Attributes were not always being populated No standard process for tracking new projects and changes CAD data process needed updating Need a process for auto-populating attributes Facility ID s, watersheds, to and from manholes etc. No editing tracking, no standard QAQC procedures GIS data was not being checked against typical water utility rules Manholes and mains not connected, upstream vs. downstream elevations Domains and feature classes did not adhere to standards required in the water utility world NASSCO (National Association of Sewer Service Companies) No domains for fields that should have them GIS needs to be connected to other databases (CCTV, CMMS etc.)

9 Review Schemas Review our original schema and see where it fits in (and where it doesn t) to the Local Government Information Model. Original Feature Dataset LGIM Feature Dataset Review Design Migrate VS.

10 Review Schemas Review the current symbology and labeling of features. Review Design Migrate

11 X-Ray for Arc Catalog Review Design Migrate Add-In tool used to develop, refine and document geodatabase designs Simple spreadsheet interface to update your schemas Analyze the differences between two geodatabase designs Merge two different designs in to a new gdb Replace and reorder fields Update field aliases and descriptions Creates a data dictionary

16 Extract, Transform, Load Review Design Migrate ESRI translated the old schema to the new LGIM schema that we had agreed upon using the ETL tools and we are pretty sure, a magic wand

17 Water Utility Editing MXD Review Design Migrate

18 Water Utility Web Map Review Design Migrate

19 New ESRI Tools to use!!! Attribute Assistant Water Utility Network Editing Tools Data Reviewer

20 Attribute Assistant What does it do, how does it work??? Used as part of our editing workflow Populate attributes when you create new features or modify existing features Rules are be created that can sequentially number features that are unique to that feature class Facility ID Server or file geodatabase setup Dynamic Value Table where you set up the rules Value Methods GENERATE_ID, INTERSECTING_FEATURE On Create, On Change, On Change Geometry, On Manual Generate ID Table Where the sequential counter info is stored

21 Attribute Assistant Generate ID Table Connected to the Dynamic Value Table SEQCOUNTER holds the number in the sequence Any rule with a [seq] will have a feature class associated with it here

22 Attribute Assistant Dynamic Value Table VALUEINFO is where the rule gets setup When the rule gets run On Create, On Change, On Change Geometry or Manual

23 Water Utility Network Editing Tools The Water Utility Network Editing solution includes 2 editing toolbars and a set of ArcMap construction tools that the City can now use as part of its editing workflow Water Utility Network Editing Toolbar Water Utility Network Reporting Toolbar Water Utility Network Editing Construction Tools

24 Water Utility Network Editing Tools Connect and disconnect geometric network features Validate features validates subtypes, attribute domains, geometric network rules, relationship rules Connection checker all junctions connect to an edge, all edges connect to another edge Split lines at selected points Merge geometric network lines Create jump overs or jump unders for intersecting lines Add laterals at connections or line locations Connect selected point to closest existing point Establish flow direction, established digitized flow direction, show/hide flow arrows Flip selected

25 Water Utility Network Editing Tools Run isolation traces valves, upstream and downstream traces Flow accumulation Add/Remove a flag Add/Remove a barrier Profiling Summary isolation trace Summary flow accumulation Change operable status of a valve Clear trace results

26 Water Utility Network Editing Tools The Water Utility Construction tools help to improve the editing experience when working with water utility data. You can add connections and laterals along with additional point features such as valves and cleanouts. The tools allow you to draw laterals perpendicular to a main from a point. You can add a point and split the line at the same time. All of these tools came with the LGIM for Water Utility and will help to drive the City of Portland s Asset Management program forward.

30 Data Reviewer What does it do, how does it work??? Review Correct Verify After running the Find Dangles data check on a small sample, Data Reviewer found one error that needs to be looked reviewed, corrected and verified

31 Data Reviewer What does it do, how does it work??? Review Correct Verify

32 Data Reviewer What does it do, how does it work??? Review Correct Verify

33 Data Reviewer What does it do, how does it work???

34 Next steps? Connecting our new GIS schema to Cityworks and begin issuing asset based work orders Start populating attribute information for all features and gathering condition information Staff training on new editing tools and Data Reviewer Web app development ArcGIS for AutoCAD Connect our CCTV software to our new GIS schema The fun goes on and on
