If the applicant fails to maintain a safe work area, or neglects to perform any restoration
within a timely manner, upon giving the applicant ten calendar days written notice
the city may maintain the site or complete the work at the applicant's expense. The
city may make emergency restorations or provide necessary maintenance at any time,
at the applicant's expense. The costs of any such work the city performs shall be
due and owing from the applicant upon completion of the work and billing by the city.
An applicant shall not be eligible to receive any additional permits under this chapter
until all outstanding billings are fully paid or, if a dispute arises as to amount
owed, the applicant provides financial security to the city in an amount sufficient
to fully secure such payment until resolution of any appeal under this chapter.
