2. Corrective Maintenance Procedures: a) Removal of Debris and Sediment: Sediment, debris, and trash which threaten the discharge capacity of the system should be removed immediately with the use of light weight equipment to avoid soil compaction and properly disposed. As noted previously, it is recommended that all water be evacuated from the system with a pump before any significant amount of sediment, settled debris or trash is removed from the system. The lack of an available disposal site should not delay the removal of trash, debris, and sediment. Temporary disposal sites should be utilized if necessary. b) Structural Repairs: Structural damage to inlet structures, roadways, and walls as a result of vandalism, flood events, settlement or other causes must be repaired promptly. The urgency of the repairs will depend upon the nature of the damage and its effects on the safety and operation of the facility. The analysis of structural damage and the design and performance of structural repairs should only be undertaken by the consulting Professional Engineer. c) Snow and Ice Removal: Accumulations of snow and ice can threaten the functioning of the inlets. Provision of the equipment, material, and personnel to monitor and remove snow and ice from critical areas will assure the function of the facility during the winter months. 3. Aesthetic Maintenance Procedures a) Graffiti Removal: The timely removal of graffiti will restore the aesthetic quality of the facilities. Removal can be accomplished by paint or other cover, or removal with scrapers, solvents, or cleansers. Timely removal is important to discourage further graffiti and other acts of vandalism. b) Grass Trimming/Landscape Maintenance: The lawn areas shall be mowed on a regular basis as necessary to maintain the lawn at a height of 2 to 3-inches (at least once a month during the growing season). These areas shall also be fertilized twice a year, once in the spring and once in the fall. Fertilizer for lawn areas shall be 10-20-10 applied at a rate of 11 lbs. per 1,000 SF or as determined by a soil test. Any bare, dead, or damaged lawn areas shall be re-seeded in accordance with the original procedures as outlined in the Soil Operation & Maintenance Manual 4 June 2024 DEC# 1021-99-025
