Phoenix may close hiking trails in its more than 40,000 acres of desert preserves during intense heat that statewide already has claimed several lives this summer.
Temperatures reaching 110 degrees would prompt the closure of city trails for people, through a policy under consideration this week. Dogs would be stopped from hiking when the mercury hits 100 degrees.
The Phoenix Parks and Recreation Board, which has authority to implement the rules, will consider the change Thursday.
The closures seek to ensure hiker safety and limit mountain rescues, said Gregg Bach, spokesman for the Parks and Recreation Department. But enforcement of the rules and the consequences for violating them still are “fuzzy,” he said.
