Whenever a Grading Permit is required, Grading Plans prepared by a registered Civil Engineer are also required. Contact the Engineering Division staff for more information on Grading Plan requirements. Whenever grading work may occur between October 1 and April 30 an Erosion Control Plan will also be required. Applicants should be aware that under certain conditions a Stormwater Pollution Prevention Plan (SWPPP), Water Pollution Control Plan (WPCP), and/or Stormwater Control Plan may also be required. Contact the Engineering Division staff to learn what other requirements may apply to your proposed grading project.
