Water Resources and Infrastructure

Protecting our water, infrastructure, and our trees is an important job. We move, clean, and manage water to ensure access to clean drinking water and healthy streams. Our forests help enhance our community by providing habitat for wildlife, clean air, and protecting our stream banks. The County relies on our infrastructure to safely manage stormwater, wastewater, and our urban forest. WRI programs aim to protect and restore our vital natural resources which serve the community and safeguard the environment and public health.
