Huisenga joined Ayres in the fall of 2024 and had been working as a senior project manager in the Stream & Stormwater group. Before joining Ayres, she served as a principal water resources lead/team lead at a Colorado firm, where she led and managed a team of over 20 scientists and planners.

She oversaw critical projects in watershed planning, wildfire mitigation, NEPA compliance, and renewable energy. She also served as a subject matter expert, guiding technical direction and advising on regulatory frameworks for water and permitting projects, establishing regulatory relationships, supporting compliance, and mitigating risks.

Huisenga’s project experience includes managing the Larimer County Water Master Plan to enhance water sustainability, providing subject matter expert support for the North Fork Wildfire Ready Action Plan to reduce wildfire risk, and managing post-fire and post-flood assessments in New Mexico.
