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)

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
