No treatment plan is provided as part of this project. <br /> F. Conveyance Analysis <br /> See Appendix B <br /> G. Maintenance and Operation Plan <br /> The City of Everett requires the owner or operator of the project drainage facility to maintain <br /> the facility in accordance with the City Maintenance Checklists. <br /> The following pages contain maintenance needs for components included in the project that <br /> are part of a drainage system. Those components must be contained within the project's <br /> Maintenance Plan.The property owner shall plan to complete a checklist for all system <br /> components on the following schedule: <br /> (M)Monthly from October through April. <br /> (A) Once in late summer(preferably September). <br /> (S)After any major storm(use 1 inch in 24 hours as a guideline). <br /> Photocopies of these pages shall be used and checked off for the problems looked for each <br /> time an inspection is completed. Comments on problems found and actions taken shall be <br /> noted. Some items do not need to be looked at every time an inspection is done. The <br /> suggested frequency at the left of each item shall be used as a guideline for inspections. <br /> The"checked" sheets shall be kept by the property owner and made available to the City <br /> upon request. <br /> The facility-specific maintenance standards contained here are intended to be conditions for <br /> determining if maintenance actions are required as identified through inspection.They are <br /> not intended to be measures of the facility's required condition at all times between <br /> inspections.In other words,exceedance of these conditions at any time between inspections <br /> and/or maintenance does not automatically constitute a violation of these standards. <br /> However,based upon inspection observations,the inspection and maintenance schedules <br /> shall be adjusted to minimize the length of time that a facility is in a condition that requires a <br /> maintenance action. <br /> Maintenance checklists are provided for the following types of facilities/structures: <br /> Closed Detention Systems <br /> Control Structure/Flow Restrictor <br /> Catch Basin <br />
