That was the message Monday night from Ben Klitzkie of Nature’s Perspective Landscaping, who said leaf blower restrictions under consideration by the City Council would add 40% to 50% to the time required for landscaping jobs. The city’s sustainability officer, Kumar Jensen, said, in a memo proposing the new set of restrictions, that he’d consulted with environmental advocates who view the leaf blowers as a major noise and environmental pollution source. But he made no mention of consulting with the landscapers who actually use the machines.
