• Re-alignment of the Crestmont egress driveway to connect into the new intersection; and, • Onsite improvements to both increase the number of parking spaces and re-design the parking around the new egress driveway. The proposed development disturbs more than one acre of land; therefore, this project is considered a “major development” from a stormwater management perspective, and the proposed design is required to address stormwater quantity, quality, and groundwater recharge requirements. The proposed stormwater management system consists of the following: • A subsurface conveyance system consisting of inlets, manholes, and pipes to convey stormwater runoff from the 25-year design storm event; • 2 small-scale bioretention basins; and, • 1 porous asphalt pavement system. 3.0 STORMWATER MAINTENANCE OBJECTIVE The stormwater management system for the proposed development is intended to collect and convey the stormwater runoff. Regular maintenance procedures are required to ensure the consistent operation and safe conditions of the stormwater management facilities and prevent the occurrence of problems and malfunctions. The maintenance program provides the stormwater maintenance procedures for the site. The maintenance plan shall be evaluated and adjusted as needed. Funding shall be allocated to cover costs of preventive and corrective maintenance. Such funding must cover the costs of staffing, equipment, materials, maintenance, emergency repairs, replacement of equipment, training of employees, administrative costs, disposal costs and permit fees. Regularly scheduled inspection and maintenance is necessary to ensure long-term operation and safety of stormwater management facilities. Inspection and maintenance procedure shall be recorded through detailed logs. Copies of maintenance related work orders shall be retained. Logs, work orders, the maintenance plan, and documentation of its evaluation shall be made available, upon request by any public entity with administrative, health, environmental or safety authority of the site. Maintenance personnel shall be trained about the purpose and operation of the stormwater management facilities. They must understand the importance of the maintenance of such facilities and the consequences of neglect. The training shall include maintenance and inspection techniques,
