Conditions attached to a land use approval are only as good as the mechanism for enforcing them years later.
Record them. A recorded development agreement or a recorded resolution describing the conditions, so that successors and their lenders take notice. Conditions in minutes alone bind the applicant and not a subsequent owner.
Tie to the permit. Conditions should be stated as continuing obligations, and the ordinance should provide that a violation is a violation of the zoning ordinance enforceable by the ordinary mechanisms.
Financial assurance. Bonds, letters of credit or escrow for site improvements, with a defined release schedule tied to inspection and a right to draw on default. Letters of credit require attention to expiry and to evergreen provisions.
Inspection and certification. As-built drawings, engineer certification, and a final inspection before the certificate of occupancy.
Ongoing conditions — landscaping maintenance, hours of operation, lighting, noise, screening — need a monitoring mechanism, since nobody will notice their lapse.
Revocation. The ordinance should permit revocation of the approval for violation after notice and hearing, which is a stronger remedy than a civil infraction.
Amendment. A defined process for modifying conditions, so that reasonable changes do not require a new approval.
