be unstopped prior to the event. This facilitates proper drainage flow in the system, reducing flooding during the event, and safeguards property. The post -event inspection is designed to check the system to again unstop any blockages that have occurred during the storm event, inspect the system for any damage that will require future repair and to ensure that any residual water left in the system can drain properly. The city is divided into four quadrants for which each division is responsible. During and after major rain events, each superintendent and crews respond to these quadrants to remove debris if possible and report their findings to the public works director. Major cleaning Ditches scheduled for major cleaning and re -grading during FY 2018-23 include 10th NW & Center, 25th SE & Sherman, 24th SE @ Dragon Park. These are identified as needing major work based upon their current condition following inspections made by division personnel. This work will include major ditch bottom clearing and cleaning to increase the capacity of the ditch and facilitate the movement of the maximum amount of drainage within the ditch. All maintenance on any ditch that requires permits from state agencies will be dependent upon the city obtaining the necessary permit(s) to complete the work. Until all permits can be obtained, the work cannot be done. The planned work may take up to 180 days per item depending on the size of the outfall ditch and the conditions found once work begins. Work priorities on these outfall ditches may change due to political considerations, major storm events or other delays not within the control of the drainage crew. Back and Side Ditches The back and side ditches that carry street water in the drainage system are cleaned as needed once a year by the same crew based upon the available scheduling. During the growing season, these ditches need to be cut and cleaned once per year and they are cleared of leaves one time per year. The crew receives assistance from street sweepers for large scale clearing of leaves from the street -side ditches citywide after all the leaves have fallen throughout the city. This particular cleaning of street -side ditches should take place in the January to March timeframe. Construction Crew Constructs new drainage infrastructure and replaces existing drainage infrastructure such as storm pipe, structures, and retention and detention ponds citywide. This crew also clears land and assists other city departments as needed when major heavy equipment activities are needed. The work schedule is determined by inspections of the systems by existing staff, in- house projects by city staff that is determined too costly to contract out. This crew also assists in removing large blockages from outfall ditches after storm events and re -grades outfall ditches between projects. Repairs existing drainage infrastructure and installs new infrastructure throughout the City of Paris. This includes repairs of cave-ins over storm pipes and structures, such as curb drop inlets, K
