Party Responsible for Maintaining Stormwater Management Facility: Property Owner 2.0 INSPECTION AND MAINTENANCE: 2.1 Routine Inspection and Maintenance of the Stormwater Management Facilities: The pervious pavement system has been designed to control degradation of water quality. Without proper routine inspection and maintenance, the system may lose some or all of its capability to function to its full capacity. Lack of adequate maintenance of this system could lead to system failures. Regularly scheduled maintenance inspections of the stormwater facilities should be performed at least four (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 structure, sedimentation and other safety-related aspects. Inspections will also provide information on the effectiveness of regularly scheduled Preventative and Aesthetic 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 maintenance of these facilities should be separated into two (2) basic types: Functional Maintenance and Aesthetic Maintenance. Functional Maintenance is further broken down into two (2) categories: Preventative and Corrective. Aesthetic Maintenance, which is necessary to maintain the visual appeal and aesthetic quality of these facilities, should be incorporated on the same schedule as the Preventative Maintenance efforts. Listed below are the Preventative, Corrective and Aesthetic Maintenance Procedures to be performed on a routine basis: 2.1.1 Preventative Maintenance Procedures: The purpose of Preventative Maintenance is to maximize the effectiveness of the stormwater management aspects of the pervious pavement system so that it can remain operational and safe and to minimize the need for potential emergency or extensive corrective maintenance. These procedures are as follows: a) Weed Growth: Weeds associated with pervious pavement systems typically fall into three (3) categories: submergent, floating and emergent. All three (3) are

All three (3) are typically found, to some extent, in a stormwater management system. However, excessive growth of any of these weeds can lead to problems. 4
