“I have been working with HW for 15+ years on numerous projects in multiple states and municipalities, and they are second to none. We have worked together on projects ranging from simple to incredibly complex, including land use and open space planning; water resource use, protection, and planning; long range and comprehensive planning; and consensus building.”
