The Summit Mosquito Abatement District has notified the Summit County Council of its intent to levy a property tax rate for the 2027 calendar year that exceeds its certified rate, a move that would represent the first tax increase in the district's 43-year history. The proposal aims to fund rising operational and personnel costs required to maintain mosquito abatement and surveillance services throughout Summit County.
Proposed Revenue Increase
According to a Summit County Council agenda from October 14, 2026, the district's proposal is expected to generate approximately $202,816 in additional ad valorem property tax revenue annually. This amount constitutes an approximate 30.77 percent increase in ad valorem property tax revenue for the district.
Management and Mission
The notification, presented by Bryan Stephens, comes as the district seeks to manage mosquito populations using an Integrated Mosquito Management approach. The district's mission is to reduce mosquito populations to acceptable levels while minimizing environmental impact, rather than attempting complete eradication, which the district notes is too costly and intrusive.
Surveillance and Control Methods
The district's operations focus on four primary areas: surveillance, larviciding, adulticiding, and record keeping. Surveillance involves technicians checking water sources approximately once a week to identify mosquito larval and pupal stages. The district also utilizes 11 standard light trap locations throughout the county to monitor adult mosquito populations.
West Nile Virus Monitoring
The district's surveillance efforts include collecting mosquito species such as Culex Tarsalis and Culex Erythrothorax, which are known carriers of West Nile Virus. These samples are sent to the Utah Department of Health Lab for testing to determine if they are infected. West Nile virus, which was first identified in Utah in August 2003, is transmitted to humans, birds, horses, and other mammals primarily through mosquito bites.
Treatment Strategies
Larviciding remains the district's preferred treatment method because it is more cost-effective and has less impact on non-target species than adulticiding. When adult mosquitoes emerge due to ineffective treatments, the district may use truck-mounted Ultra-Low Volume aerosol generators to apply adulticide in a fog during the evening when mosquitoes are most active.
Legislative Context
The tax increase process follows statutory procedures required by Utah Code for entities proposing budgets that exceed their certified tax rates. For calendar year entities, these hearings and adoption timelines typically occur during the late summer and fall.
