(Portland, OR)  --  Gas powered leaf blowers would be banned in Portland after 2026 under an ordinance being considered by City Council.  They would be allowed from October through December, because of heavy wet leaves.  A full ban would take effect in 2028, as long as electric leaf blower technology advances.  The City Council would review technology in September 2028 and could extend the temporary use.  Property owners would be fined for violations.  The first violation is a warning and then fines range from 250 to one-thousand dollars.  Some money would be available to help small landscaping companies convert to electric leaf blowers.
