HMMH has analyzed noise and air quality for hundreds of transportation projects throughout the U.S, including Environmental Assessments (EAs) and Environmental Impact Statements (EISs) under the National Environmental Policy Act (NEPA).
HMMH offers the aviation industry advanced, cutting-edge capabilities and experience related to identification, assessment, and implementation of Performance Based Navigation (PBN) procedures and is currently assisting the FAA in a large-scale implementation of PBN across the US. We have written guidance for transit noise and vibration issues and solar power at airports. HMMH’s technical services are focused on interrelated disciplines, which allow us to streamline analyses by minimizing duplication of effort and using proprietary tools.
