All landscape installation shall be completed prior to final inspection. If the installation is incomplete at the time of formal application for occupancy because of weather-related reasons, the City will require that the applicant submit a bond or some other form of cash surety acceptable to the City at a value of 150 percent of the cost of installation of the remaining materials as evidenced by a submitted bid price from an acceptable source. If the required landscaping is not made within six months of the occupancy of the building, the City will use the surety to install the landscaping.
