Green infrastructure – just like grey – requires regular inspections and maintenance. But once the project is built, who takes on this job to assure proper function and the community benefits are realized? This presentation explores two GI maintenance approaches – contractor provided maintenance and owner provided maintenance. We will examine the opportunities and challenges, as well as the pros and cons of each method. We will look at two examples – the King County Waste Treatment Division Barton Roadside Raingardens and the King County Rainwise program – to see how each approach differs, yet helps manage stormwater as a resource and asset.

Upon completion of this course, attendees should be able to:

• Manage expectations in long term GI Maintenance
• Develop a successful contracted maintenance program
• Develop a successful owner or volunteer maintenance program
• Use checklists and reporting systems to track GI maintenance
