Project with an environmental impact
Planning permission

The approach to a project with an environmental impact is identical to that of the cases seen in section 1; however, an addition has been made to the mayor's response.

This addition concerns the project, which must also comply with regulations on water and protected species of flora and fauna. Thus, if the project involves an installation, work or activity (IOTA) subject to authorization (or simple declaration), the applicant must apply for an administrative authorization from the prefecture of his department.
