Who We Are

TerraLogic is an environmental consulting firm with expertise in sustainability and risk management in the infrastructure and transportation fields. 

We provide a wide range of sustainability-based consulting services to infrastructure-based clients to support their programs and projects

We support the transportation industry, municipalities and private sectors with a range of sustainability-based services which include infrastructure vulnerability and climate change risk management, sustainability-based program and project development, alternative energy impact studies, and stormwater and water quality management. We are known nationally and internationally for our ability to integrate sustainability principles and concepts into infrastructure programs and projects such as in our work for the World Bank in Latin America and USAID in Liberia. 

As a small environmental engineering consulting firm, we excel when teamed with a larger firm to lead or support a project or as a prime contractor where we can take the lead in applying our expertise to solve environmental problems. We are broad based; we provide environmental management services to all facets of the infrastructure development process involving planning, design, construction and operation and maintenance. 

TerraLogic’s Principal Owner, Art Hirsch, is a respected national authority on these very topics and will help bring our nation’s infrastructure to higher level. He has over 30 years experience in the environmental consulting field and over 15 years as a transportation environmental consultant.
