PART II: INSPECTION AND MAINTENANCE A. Routine Inspection and Maintenance of the Stormwater Management Facilities: The stormwater management basin has been designed to control stormwater and reduce downstream impact. Without proper routine inspection and maintenance, the basin may lose some or all of its capability to function to its full capacity. Lack of adequate maintenance at this facility could lead to system failures. A consulting Professional Engineer should perform regularly scheduled maintenance inspections of the stormwater facilities at least (4) times each year. The primary purpose of these inspections is to ascertain the operational condition and safety of the facilities, particularly the condition of outlet structures and other safety-related aspects. Inspections will also provide information on the effectiveness of regularly scheduled Preventative Maintenance Procedures, and will help to identify where changes in the extent and scheduling of the procedures are warranted. Finally, the facility inspections should also be used to determine the need for and timing of Corrective Maintenance procedures. Routine Functional Maintenance is required to insure the safe and effective operation of the storm water management facility and is further broken down into two (2) categories: Preventative and Corrective. It is important to note that a successful Functional Maintenance program will emphasize regularly scheduled Preventative Maintenance over emergency-based Corrective Maintenance. Listed below are the Preventative and Corrective Maintenance Procedures to be performed on a routine basis: 1. Preventative Maintenance Procedures The purpose of Preventative Maintenance is to assure that the basin remains operational and safe at all times, while minimizing the need for emergency or corrective maintenance. These procedures are as follows: Bioretention: a) Grass Cutting A regularly scheduled program of mowing and trimming of grass at and surrounding the basin during the growing season will help to maintain a tightly knit turf, and will

ed program of mowing and trimming of grass at and surrounding the basin during the growing season will help to maintain a tightly knit turf, and will also help to prevent diseases, pests and the intrusion of weeds. The actual mowing requirements of an area should be tailored to the specific site conditions, grass type, and seasonal variations in the climate.
