1 Performing Cost Effective Asset Management Inventories Utilizing GIS Steve Tyler, Public Works Superintendent Mark Dumford, Consultant

2 Town of Atherton South San Mateo County 5 square miles Approximately 6,900 total population Approximately 2,500 households Almost all residentially zoned 57 miles of street centerlines Trees, trees, trees

3 Problem Statement The Town of Atherton did not have an accurate source of the locations and the physical conditions of asset information. This included street lights, storm drainage infrastructure, and street signs. This gap in knowledge made it difficult to plan the programs and costs necessary to maintain these features.

4 Collection Goals and Budget Goals Collect and document the all of the locations and physical characteristics of street lights, storm drainage infrastructure, and street signs. Use the newly collected data to assist in asset management decisions and associated maintenance costs. Project Budget $20,000 - $30,000

5 Project Constraints Limited budget No quality sources of asset information locations No asset management system for asset characteristics Short deadlines due to staff availability to support collection and pending street light project. Poor cell coverage throughout city Dense tree coverage limits aerial photo and street level imagery being used to assist in data collection effort

6 Data Requirements 10 feet spatial accuracy different physical characteristics of each feature Capture surface photo of each asset Capture photo and characteristics within storm inlets and manholes structures Collected data available to staff in an easy to use viewer

7 Collection Methodology Plan Develop and agree on database design Develop GIS solution to collect required information ArcGIS Online cloud based GIS to store and publish map information and asset data. Subscription license required. Free ArcGIS Collector app install on ipad to perform field collection consumed from ArcGIS Online. Use pilot project to test GIS solution and adjust process according to results of field testing Train staff on field collection solution. Perform full field collection with support of GIS staff Provide simple to use WebGIS platform to Town staff to view and query collected asset information.

8 Database Design Street Lights

9 Database Design Storm Drainage

10 Database Design Street Signs

11 GIS Solution Overview Cloud based ArcGIS Online WebMap and Feature setup Field collection using phone or tablet ArcGIS Collector app and GPS

12 Pilot Collection and Feedback After database design and collection solution is prepared: Choose a subject matter expert (SME) to collect small geographic sample and a cross section of feature types. GIS staff should monitor process closely and seek immediate feedback from SME. Test for mobile signal strength. If needed go with full disconnected solution. Make adjustments to process and database design if necessary.

13 Training for Field Staff Training should happen in the field if possible. Focus on training lead field staff. They can train others if needed. Interns are a good resource for this type of work. Cost effective and good experience. Use of tablets or smart phones allows for easier user training with device familiarity. Provide GIS support contact info for troubleshooting.

14 Full Collection Street Storm Signs Water Lights Inlets 1, Weeks

15 Support and Quality Checks GIS Staff should be available for rapid response to issues reported by field staff. Data collected in the field available for project managers in real-time via WebGIS viewers.

16 Using the Newly Collected Data General WebGIS viewers to research location and feature characteristics Tracking future asset inspections and maintenance work. Summarize information for asset replacement program development.

17 WebGIS and Mobile Collection Demo

18 Important Points Advances with mobile technology make collecting and managing assets streamlined and efficient. A simple and well-organized data design will help to drive the collection process. A mobile data plan is not necessary, but it can be beneficial. Interns can be a great resource for field work. Starts with a basic ArcGIS Online subscription. GIS data layers and a WebGIS solution are not a replacement for a fully functional Asset Management System
