HDL’s Environmental Services Group has the expertise to aid clients in the National Environmental Policy Act process and the development of appropriate environmental documentation. In addition, our detailed permit applications, coupled with our knowledge of local resources and positive relationships with the agencies, facilitate timely permit approvals and clearances for our clients’ projects.

We have extensive experience developing Categorical Exclusions and Environmental Assessments for Federally-funded projects as well as State Environmental Checklists for State-funded projects. We provide a proactive approach to the development of environmental documentation to ensure projects do not experience unnecessary delays.
