The Assistant Manager’s report describes extensive aerial operations in May and early June, including helicopter-applied granular larvicide treatments over several hundred acres near Highway 37, at Tolay Lake, and at the Ellis Creek Water Recycling Facility. The FY 2026/27 and 2027/28 budgets allocate $240,000 and $255,000 respectively for aerial services, plus additional funds for aerial surveillance, underscoring a recurring need for aviation partners and application logistics. This combination of operational activity and budget line items indicates an ongoing program of contracted aerial mosquito control, likely through specialized aviation vendors.While incumbents are not named, helicopter service providers, aerial mapping firms, and product manufacturers supporting large-scale larvicide applications can position themselves for future contracts or expansions as the District continues high-intensity control in floodplains, wetlands, and water facilities.

Operations involve coordination with Sonoma County Regional Parks, Graton Rancheria, Ellis Creek Water Recycling Facility, and Las Gallinas Valley Sanitary District, suggesting interagency collaboration requirements for aerial work.
