Major Impact Projects


Major Impact Projects require the consideration by the county of a Sketch Plan, Preliminary Plan, and Final Plan, in that order.

What to Expect

Each step is a distinct process involving the submission of an application, an application fee, required plans and reports, referrals of the proposal to other agencies, staff analysis, work sessions, and public hearings.

At each step of the process the design and engineering detail increases in order to relieve the applicant from major and potentially unnecessary expenses in situations that may require a redesign and a revision of expensive engineering or planning reports.


Final approval is only issued following review and approval of the sketch plan, preliminary plan and the final plan.
