General Maintenance Procedures The structural and functional integrity of the Facility shall be maintained at all times by removing and preventing drainage interference, obstructions, blockages, or other adverse effects into, through, or out of the system. The stormwater quality device shall be cleaned and cleared of all sediment shortly after project completion. Generally, a sump -vacuum truck is the most convenient method of removing the captured sediment and floatables from large underground structures. Floatables and oil should be removed in a separate procedure prior to the removal of accumulated sediment from the bottom of the underground storage chambers. The structural and functional integrity of the Facility shall be maintained at all times by following the manufacturer recommendations for maintaining the system. Flushing of the system by hose or other method that may move sediment to the downstream storm sewer system is unacceptable. Periodic silt removal shall occur when standing water conditions occur or the underground storage volume is reduced by more than 10%. This maintenance should be performed as needed based on inspection but is recommended annually. In addition, corrective measures are required any time a basin does not drain completely within 72 hours of cessation of inflow. Accumulated litter, sediment, and debris shall be removed every 6 months or as necessary to maintain proper operation of the basin. Disposal shall be in accordance with federal, state and local regulations. To prevent debris from entering and clogging the downstream storm sewer system a wire mesh screen or similar screening device shall be installed over the outlet until final acceptance. PREVENTIVE MAINTENANCE/INSPECTION Visual inspections of all components will be conducted every 6 months. A log shall be kept of maintenance actions, and inspections. The log should document the condition of the detention system's primary components, silt, litter and debris removal dates. Document any replacement or maintenance of structures. Written maintenance and repair records shall be maintained by the party or parties signing the attached Agreement and shall be provided to the City upon request STORMWATER FACILITY MAINTENANCE AGREEMENT Rev. 3/20/2019 Retaininu Wall Maintenance Like all manmade structures, retaining walls are prone to natural wear and tear that will reduce their lifespan. Here are some of the best ways to keep this from happening that will help you get the most out of your retaining wall. Maintain landscaping along wall It might sound crazy, but just because weeds are minuscule next to a retaining wall doesn't mean they can't cause damage. Weeds pose one of the biggest threats to retaining wall durability. As they grow between small spaces and cracks in the wall, they can expand and create gaps and shifts. These can lead to wall cracking and damage, thus shortening the life span of the retaining wall and leading to costly repairs. Therefore, it's essential to regularly pick weeds around your retaining wall and to apply weed killer bi-annually. In addition, it is important to maintain the landscaping against the wall in a good condition. Prevent overgrowth or planting trees or bushes near the wall to avoid roots undermining the wall. Grass and plants will help to hold the soil around your retaining wall in place and provide a firm foundation. This will keep the ground from shifting, which will lead to movement in your retaining wall. Therefore, you should regularly check the ground around your retaining wall for bare spots and make remedies immediately. Inspect the wall regularlv During routine maintenance of the site or during walks of the property, check for signs of movement or shifting along your retaining wall. Even the smallest shift can indicate a potential problem and the need for repair. If you notice movement, contact a trusted retaining wall contractor for further evaluation. Other things to look for are growing cracks, bulges in the wall surface, water seepage through the wall, etc. Any of these items could indicate a problem in the retaining wall that should be investigated further. Don't Use Eroding Materials Near Your Retainina Wall For retaining wall, do not coat or spray the retaining wall or the adjacent areas in salt or a de-icing material. These chemicals, like others, will lead to erosion of the wall face. They can cause cracking and pitting, which will further deteriorate the wall surface. Ice and snow aren't good for your retaining wall, they aren't as detrimental as salt or di-icers that lead to erosion. Avoid impacts to the wall surface and follow any recommended surface treatments to the wall face as required to lengthen the life span of the wall. Ensure Adeauate Drainage Depending on the type of location of your retaining wall, it might have built-in or nearby drainage. It's vital to keep this drain clear of obstructions so that water can smoothly drain away from the wall. This is especially important during cold weather, where ice and snow can build up. As the ice and snow melt, it can lead to erosion if it's allowed to pool around the retaining wall due to a blocked drainage. If retaining wall erosion begins to occur, it is important to reach out to a retaining wall contractor right away. It is also important to check weep holes to make sure they do not become plugged up with soil. Underground Detention Pipe Maintenance Maintenance Underground storm water detention and retention systems should be inspected at regular intervals and maintained when necessary to ensure optimum performance. The rate at which the system collects pollutants will depend more heavily on -site activities than the size or configuration of the system. Inspection Inspection is the key to effective maintenance and is easily performed. The system should have quarterly inspections of the accumulated sediment. Sediment deposition and transport may vary from year to year and quarterly inspections will help ensure that systems are cleaned out at the appropriate time. Inspections should be performed more often in the winter months in climates where sanding operations may lead to rapid accumulations, or in equipment washdown areas. It is very useful to keep a record of each inspection. Systems should be cleaned when inspection reveals that accumulated sediment or trash is clogging the discharge orifice. All systems be designed with an access/inspection manhole situated at or near the inlet and the outlet orifice. Should it be necessary to get inside the system to perform maintenance activities, all appropriate precautions regarding confined space entry and OSHA regulations should be followed. Cleaning Maintaining an underground detention or retention system is easiest when there is no flow entering the system. For this reason, it is a good idea to schedule the cleanout during dry weather. Accumulated sediment and trash can typically be evacuated through the manhole over the outlet orifice. If maintenance is not performed as recommended, sediment and trash may accumulate in front of the outlet orifice. Manhole covers should be securely seated following cleaning activities.
