If some people don't support the formation, can they prevent the division forming?

If a 2/3 majority of the property owners are willing to sign irrevocable offers of dedication and those controlling the easements is obtained, the formation can proceed. Noticed public hearings are held by the Board of Supervisors where protests can be heard. If the division formation is approved despite the protests of an individual parcel owner, that owner will be taxed along with all other parcel owners in the division.
