Greenway Alert: Greenways Impacted By Flooding UPDATED SEPTEMBER 10, 2019

Closed for walking and biking but open space serving as natural flood plain during high water

Many greenways parallel area rivers, creeks and streams and are currently closed or impacted by flooding. While you can’t walk or ride right now, the flooded greenways are still serving an important purpose as a natural flood plain.  The water can spread out across the undeveloped open space during high water and then recede when river levels drop.

We post alerts on each individual greenway page to let you know about closures due to flooding, construction, maintenance or other issues. We update this information based on reports from partners, our staff and greenway users.  Note that once river levels drop, it may take a few weeks to clear any sand or debris left behind to reopen affected greenways.  Here is a comprehensive list of flood closures/impacts as of September 10, 2019:
