Environmental Review Documents
At Zone 7, we are fully committed to delivering our services with sensitivity to our environment, which means we take the environmental impact review process seriously. An environmental review is an evaluation a project and its potential environmental impacts to determine whether it meets local, state and federal environmental standards.
Some Zone 7 projects require an environmental review process to ensure the proposed project does not negatively impact the surrounding environment and the site will not have an adverse environmental or health effect.
