HWA Program is Changing

Our priorities and structure are evolving to ensure that we can continue to address the HWA infestations across our four-county service area effectively. In March 2026, we will be transitioning away from our 100% grant-funded efforts to a cost-share model for HWA quote for services, delimitation, and treatment efforts. This change reflects adjustments in funding at the state level, as treatment costs increase and new HWA infestations have added additional strain on funding availability. See more details in our October 2025 eNews.
