Introduction: The proposed RiteAid #5231 requires compliance with the current City of Everett drainage code. These following guidelines represent the maintenance requirements for the existing and proposed on-site drainage facilities. These requirements shall be performed by the property owner or maintenance service in accordance with current City codes. Plan Goal The specific purpose for the storm water facility is to minimize pollution that is typically associated with modern development. In general, pollution from motor vehicles and pollution generated from erosion. Attached to this narrative is a maintenance manual, which offers guidelines to the owner for storm water facility maintenance. On-Site Stormwater Facility Maintenance Requirements Regular inspections of the drainage facilities should be carried out twice per year, in the spring and fall. The responsible party should keep records of these inspections available for review by the City. Additional inspections may be required after severe seasonal storms. Routine maintenance of the site will include mowing, care of landscaping and the removal of trash and debris from the drainage system. The parking lots and driveways should be kept clean and in repair. Events such as major storms or heavy winds will require immediate inspections for damages. The following is a list of the on-site storm drainage facilities and their function. Also attached are the required maintenance requirements for these facilities. • Control Structure - stormwater discharge restrictor assembly • Catch Basins - collect surface drainage • Conveyance Pipes - convey catch basin and roof drainage • Grounds/ Landscaping - prevent erosion of unpaved areas • Stormfilter Treatment MH —provide water quality treatment • Stormceptor Pretreatment MH— provide pretreatment prior to Stormfilter Responsible Organization: Nicholson Development Properties 2333 Carillon Point Kirkland, WA 98033 Contact: Daniel Taylor Phone: (425) 827-7499
