Division of Environmental Planning

Ron Kosinski
Deputy District Director for Environmental Planning

"I believe that the people of California appreciate our hard work and inventiveness in ensuring that Caltrans projects are planned and constructed to be as environmentally sensitive as possible."

Mission Statement:
The Division of Environmental Planning (the Division) serves the environmental needs of District 7 (Los Angeles and Ventura Counties). It consists of a multi-disciplinary team of over 50 individuals with specialties in a wide range of areas such as environmental analysis, biology, archaeological resources, architectural history and social community impacts assessment. The Division of Environmental Planning also coordinates with other specialists in air, noise and water quality, landscape architecture and hazardous materials testing.

The Division administers Caltrans' responsibilities under federal and state law in response to the enactment of the National Environmental Policy Act (NEPA) of 1969 and the California Environmental Quality Act (CEQA) of 1973. In response to the passage of a host of environmentally related laws and regulations, plus heightened public support for the environment, our environmental responsibilities have grown to become a substantive and inseparable part of Caltrans' planning, development, construction, operation and maintenance efforts.

The Division of Environmental Planning is a critical functional unit which must have a clear vision to be successful. Our primary vision, which shared with all of the District Offices, is to ensure the timely delivery of environmentally sound projects.
