37 Miss. Code R. § 1-7501-09002-1201
The Applicant will be required to erect permitted sign(s) so that all sign faces are visible above the tree line. The State Maintenance Engineer's designated agent will make final inspection of the permitted sign and determine whether the sign is above the tree line and take a photograph. The owner of the permitted sign will be advised if the sign is not above the tree line and will be required to raise the height of the sign or the permit will be forfeited and the sign must be removed. If the sign cannot be raised above the tree line without exceeding the maximum height of sign, the permit will be forfeited. Applications for permits to erect signs which are not visible due to existing landscaping of the right-of-way will be denied.
