Boise Mayor David Bieter and Garden City Mayor John Evans ordered the closure of most of the greenbelt Thursday due to dangerous flood conditions.
This comes on the heels of Wednesday's announcement of pathway closures in Eagle.
The joint announcement leaves all but approximately 11 miles of the greenbelt in Ada County open to the public.
The largest stretch open in Ada County is from Lucky Peak towards the Warm Springs Golf Course. The section in and around the Marianne Williams Park and Bagley Park is closed. The majority of pathways from the Warm Springs Golf Course north to Plantation River Drive is closed.
The South side next to Boise State University is open and a little bit near the Whitewater Park and the Willow Lane Complex is open.
From plantation to the Ada County line, the entire greenbelt is closed.
These closures have the potential of being in effect until June.
"While the greenbelt may look safe, we don't know what's happening under the bank. We don't know what's happening underneath the ground. We don't know if that tree right by the greenbelt is secure or not and could be coming down," said Mike Journee, City of Boise spokesman. "We've just never seen these types of conditions before, and we don't know how it's going to manifest itself."
The water has washed away pavement along several sections of the greenbelt and trees have come loose.
So, if you use the pathway as a way to commute to work, you'll have to find other means.
Boise police, parks and recreation workers, along with volunteers will be working to educate the public on the closures. However, if you're caught violating the blockades, you could face a citation and fine.
Signs and blockades have been posted at key junctions.
Another potential threat that's being closely monitored is the Boise Wastewater Treatment Plant.
The facility itself sits on ground higher than the surrounding area. It's more of an access concern at this time.
There is only one roadway to reach the plant. While it can be operated remotely, personnel and equipment would eventually need access.
For now, manhole covers in low-lying areas are being sealed so that extra water doesn't get into the sewer line since the plant can only process so much water at one time.
