IX. MAINTENANCE PLAN A. Introduction This section contains requirements anticipated for ongoing operation and maintenance for the Recommended Plan features. Table 6 - Recommended Plan Estimated Maintenance Costs Project Annual Maintenance B. Operation & Maintenance Guidelines Through partnerships with the agencies involved, it is recommended that local jurisdictions be responsible for maintenance <strong>of</strong> the proposed channels and detention basins. Maintenance should be such that grass, earth, and other channel and basin linings reflect the “n” value as shown on the preliminary design plans. Specific maintenance tasks should include but not be limited to: - Yearly inspection <strong>of</strong> structures - Routine landscaping maintenance, and - Inspection/cleaning <strong>of</strong> facilities after major storm events. C. Maintenance Costs Based on information provided by the FCDMC, an average maintenance cost was interpolated to be $0.025 per square foot <strong>of</strong> right-<strong>of</strong>-way per year. This cost was derived by comparing actual maintenance costs <strong>of</strong> existing channels and basins which are similar to the proposed ADMP channels in shape, size and landscaping. The annual maintenance costs for the recommended projects are shown in Table 6.
