Arborist Reports, Tree Risk Assessment, and Consulting Arborist Services in Marin, Sonoma, and Napa Counties

Urban Forestry Associates, Inc. is a team of consulting arborists providing arborist reports, tree risk assessment, tree protection plans, and expert witness services. We work with homeowners, attorneys, developers, and public agencies throughout Marin, Sonoma, and Napa Counties.

Because we do not prune or remove trees, our recommendations are independent and based on field observations, industry standards, and professional judgment.

who we work with

We work with homeowners, property managers, attorneys, developers, architects, planners, and municipalities who need clear, defensible guidance about trees. Our work often supports permit applications, development planning, risk management, and legal cases.

See Selected Projects for example project summaries.
