If said deposit shall be insufficient, such
additional sums as may be necessary shall be paid by the applicant
before approval is granted. If the application is denied or withdrawn,
the applicant shall pay said additional sums also. Failure to do so
may result in legal action, including but not limited to placing a
lien on the property which is the subject of the application. Any
balance from the deposit, after all review and inspection costs and
appearance-at-meetings costs have been deducted therefrom, shall be
refunded to the applicant.
