The City of Ojai has now been Certified as the first AGZA Green Zone®City in Ventura County, and the second city-wide AGZA Green Zone in the United States. American Green Zone Alliance (AGZA) certified the sustainability achievement at a public ceremony in Ojai’s Libbey Park, Friday April 12th.

Ojai’s city-wide AGZA Green Zone now protects 52 acres across 19 municipal properties, including all parks and sports fields and city hall, in perpetuity.


AGZA Green Zone City Certification establishes and verifies that all routine grounds maintenance on municipal properties — mowing, hedging, edging, trimming, sawing, and blowing — are serviced exclusively with low-noise zero-emission battery-electric equipment and manual hand tools. AGZA Green Zones are the most rigorous sustainability criteria in the world for eliminating the health and environmental impacts of the lawn & garden industry.


Every year Ojai’s AGZA Green Zone prevents the creation of over 82 tons of CO2, CO, HC, PM2.5, and NOx from the city. Noise has been permanently reduced by 40% to 70%. Fuel spillage, evaporative emissions and solid waste from gas maintenance have been completely eliminated. Significant reductions in hourly operational costs from the gas fleet — fuel, oil, parts, and maintenance — will achieve a healthy ROI on the new electric fleet, and ongoing savings thereafter.

• CARBON DIOXIDE (CO2) eliminated
• CARBON MONOXIDE (CO) eliminated
• HYDROCARBONS (HC) eliminated
• PARTICULATE MATTER (PM 2.5) eliminated
• NITROGEN OXIDES (NOx) eliminated

• Ojai’s city-wide AGZA Green Zone® is complete and certified. All routine grounds maintenance across 52 acres and 19 properties are now serviced by low-noise zero-emission equipment and operations (see map below).

The AGZA Green Zone has been designed, implemented, and verified to substantially reduce noise and entirely eliminate air pollution and gas-related fuel, oil and parts forever.

• All gas-powered machines formerly used for Ojai’s routine grounds maintenance have been decommissioned. The VCAPCD grant which funded the electric fleet procurement mandates the gas tools be scrapped to permanently prevent all future pollution.

The gas fleet has been completely replaced with an AGZA approved commercial-grade electric fleet. The new battery-electric tools, battery bank, and charging infrastructure were specified and proven to have ample power, performance, run-time, durability, and operational aesthetic for full-time city-wide commercial operations.

• The Ojai grounds workforce has been educated and trained on the new electric fleet for optimal operation, including safe battery management and charging procedures. The crew are now certified AGZA Service Pros.

• Substantially lower hourly operational costs of the electric fleet will provide significant financial savings over gas operations. Net operational savings will compound annually to achieve a healthy ROI.

The noticeably quieter, cleaner AGZA Green Zone grounds operations throughout the city’s parks, sports fields, and municipal properties will serve as a permanent sustainability inspiration. Families, schools, businesses, and commercial crews may consider transitioning their own lawn and garden care to quiet, zero-emission equipment, further benefiting the quality of life in the Ojai Valley.

“this is just hilariously cost effective and is low-hanging fruit that we really should be embracing overall.”

— Dr. Steve Colomé, Ojai Valley Representative to the APCD Advisory Committee

“ojai has demonstrated that you can run an entire public works department on battery-electric equipment.”

— Michael Villegas, Air Pollution Control Officer, VCAPCD

“we definitely know it is a matter of changing our habits, learning to plug in instead of refuel. but the benefits are really tremendous, not only in cleaner air for the community but also reduced exposure to toxic emissions for the workers and also improving our climate.”

— Catherine Dunwoody, Chief, Monitoring and Laboratory Division, CARB

“this was by far the best investment — in my view — that we made in the twenty years that the clean air fund has existed.”

— Mike Stubblefield, Chair, Clean Air Fund Advisory Committee

“hey! it actually did work. some of our fears were misplaced, and if we evolve into this we can do it with minimal disruption.”

— Johnny Johnston, City of Ojai Mayor

“this project demonstrates how battery-operated equipment is not some science fiction thing, that it is here and ready for prime time. and with a little confidence of the people getting behind it, that it can be commercially successful. ”

— Johnny Johnston, City of Ojai Mayor

“we love working with people. building trust, forming bonds, and becoming part of a community such as ojai is incredibly rewarding.”

— Dan Mabe, Founder + President, AGZA

“ojai has reached the federal standard of 70 parts per billion well ahead of schedule. so I think you should congratulate yourselves.”

— Michael Villegas, Air Pollution Control Officer, VCAPCD

“the story of this success is already echoing throughout southern california and across the country. your agza green zone gives the next community, the next school, and the next air district the confidence they seek to move ambitiously toward sustainable and responsible grounds maintenance.”

— Luke Massman-Johnson, CFO + Communications Director, AGZA
