After the initial fertilization to establish the grass in the vegetated conveyance or the vegetated receiving area, fertilizer will not be applied to the vegetated receiving areas. The vegetated conveyance or vegetated receiving area will be inspected quarterly. Records of operation and maintenance will be kept in a known set location and will be available upon request.

Excess - debris can clog the system and lead to bypass of the design storm, reducing infiltration and pollutant removal. To ensure proper operation as designed, a licensed Professional Engineer, Landscape Architect, or other qualified professional will inspect the system annually. - The system components will be repaired or replaced whenever they fail to function properly. After the DIS is constructed, it shall be inspected quarterly. Records of operation and maintenance shall be kept in a known set location and shall be available upon request.
