            3.   The bond or other surety shall be held for a period of 18 months after installation of plantings to assure proper maintenance and growth. Failure to maintain the vegetation and to replace dead plants or trees shall result in a forfeiture of the posted bond or other surety.
            4.   Prior to the, release of the bond, the site shall be inspected by the village upon notification by the applicant to assure proper maintenance and installation.
