Grading permit

A Grading Permit is required for any proposed change in grading. The ordinance, which was adopted in 2012, requires that these changes be designed by a Licensed Professional Engineer and completed in a manner that does not adversely impact any neighboring property or the public right-of-way. A copy of the current Grading Permit Ordinance (Title 4, Chapter 17) can be viewed here
