The Need Stormwater Asset Tracking Needs are Increasing!
NPDES Permit – outfall mapping, BMP inventory, ICID TMDL/Watershed Mandates Reporting
Other Needs Life‐Cycle Cost tracking Dept Health Services (standing water and vector control)
Operation & Maintenance Prioritization of Capital Improvements

What and why Asset Management
Comprehensive asset management programs for stormwater infrastructure
Capital and Operations and Maintenance Planning Use technology to support a sustainable stormwater program
All agency divisions could benefit Capital Improvement Planning, Design, Development, Construction, Maintenance, Landscape/Parks, Stormwater Management

Innovative Information Technologyfor Asset Management (Tools)
Web‐based tracking inventory (maps)
Mobile tools – data collection, inspections, photo documentation
Drones for watershed‐scale and regional‐scale inventory

Usefulness for your Stormwater Program
COTS (Commercial Off-the-Shelf) asset management software• Lower cost vs custom• Scalable building block-like options?• May not find one that fits all your organizational needs• Longevity
• IT support cost• Will vendor still support my platform version?
COTS
Summary NPDES Permit and Watershed Plans/TMDLs require intensive tracking needs for stormwater systems (outfalls, BMPs, O&M)
Use of Innovative technology will improve data collection and management and use by design, maintenance, and construction of stormwater controls
Automated information technology is needed for managing a sustainable stormwater management program
