City or State designating the City or State as the responsible party for maintaining all or a portion <br />of Anoka County's Stormwater Ponds. <br />2.03 The City of Ramsey is responsible for inspecting and maintaining stormwater ponds within any <br />City right-of-way or City -owned property unless a maintenance agreement exists between the <br />City and the County or State designating the County or State as the responsible party for <br />maintaining all or a portion of the City's Stormwater Ponds. Stormwater management facilities <br />will be inspected on a routine basis to ensure they continue to function as designed. The <br />inspection requirements set forth herein were developed to provide City staff with practical tools <br />to inspect and maintain all stormwater management facilities on a proactive and routine basis. <br />a. Stormwater Pond Inspections — To start, 5% of all known stormwater ponds that the City <br />is responsible to maintain will be inspected annually, starting at the Mississippi and Rum <br />Rivers and working inland to the north and west. Initial inspections will consist of enlisting <br />consultants to survey ponds to determine how much stormwater storage capacity <br />remains and to schedule pond dredging projects to remove sediment and restore storage <br />capacities. Ongoing inspection requirements include observations for blockage of outlets <br />due to trash, debris, vegetation, or downed trees. Blockages shall be cleared from <br />obstructed outlets as soon as practical. Damaged or deteriorated inlets, outlets and pipes, <br />and malfunctioning valves, gates, locks or access hatches, shall be scheduled for repair or <br />replacement as soon as is economically feasible to do so. <br />b. Drainage Structure Inspections — Drainage structures, castings and trash guards will be <br />inspected for debris and repair needs during development of pavement management <br />projects, during flood events, or at a minimum once every 5 years. Structure sumps shall <br />be inspected a minimum of every 4 years to determine if the sump needs to be repaired <br />or pumped. Sumps in new developments are checked within one year after completion <br />of the development to determine if cleaning is required. <br />c. Drainageway Inspections — Drainageways will be inspected for debris and repair needs <br />during development of pavement management projects, during flood events, or at a <br />minimum once every 5 years. Structure sumps shall be inspected a minimum of every 4 <br />years to determine if the sump needs to be repaired or pumped. Sumps in new <br />developments are checked within one year after completion of the development to <br />determine if cleaning is required. <br />d. Lift Station Inspections — The structure and pumping equipment will be inspected <br />annually. <br />e. Storm Sewer and Culvert Inspections - Video inspections shall be conducted during <br />development of pavement management projects or when public complaints or concerns <br />are received. <br />f. Inspection documentation, maintenance recommendations, and requests for routine and <br />emergency maintenance — All associated documents shall be submitted to the Public <br />Works Administrative Assistant, who will then prepare and process Work Orders for <br />3 <br />
