Asset Categorization Assets will be organized into classes based on: ü Public health, safety, welfare (built assets) ü Ecosystem and habitat (natural assets) ü Social vulnerability (human assets)
Data Collection • Open Data Portal – available here: http: //slrsmc. smcmaps. opendata. arcgis. com/ ü Still working on filling in dataset ü Needs review for completeness
Data Sets - Stormwater* - Wastewater - Fire - Roads - Transportation/ Railroads - Energy infrastructure - Airports - Clean up sites - Solid Waste facilities - Underground Storage tanks - Closed landfills - Schools - Senior Centers - Hospitals - Affordable housing units* - Evacuation routes - Parcel data - Port facilities* * Data still needed
Next Steps • • • Inventory of Assets Short List of potential representative Assets Your review and feedback on Short List Selection of 30 assets Asset manager interviews and research Develop Asset Vulnerability Profiles
