The log shall be made available to the City of Bozeman Public Works Department for review as requested. Land Use & Site Area: The project site is located at 3100 West Main Street and zoned B-2 – Community Business District. The site consists of one building with an asphalt parking lot. The site will be landscaped according to approved landscaping plans and must meet the City of Bozeman Unified Development Code. Storm Water Management Systems: The storm water management system includes a system of inlets and piping that routes stormwater runoff to an underground retention chamber system in the parking lot. Inspection & Maintenance Storm water facilities and permanent Best Management Practices (BMPs) must be inspected in accordance with this document. All documentation on scheduled inspections, times of inspections, maintenance completed, remedial actions taken to make repairs, and any modifications or reconstruction of the storm system shall be maintained on-site. Disposal of the accumulated sediment must be in accordance with all applicable local, state, and federal guidelines and regulations. If any drainage structure or outfall indicates the presence of petroleum, the petroleum material shall be removed and disposed of immediately in accordance with applicable regulations. All estimated costs are based on labor rates assumed in 2025. Velocity Carwash Storm Water Operation & Maintenance Manual 2 Pavement Sweeping & Vacuuming: All paved areas shall be swept twice a year, scheduled in spring and fall. Estimated Annual Cost: $500 Strom Drain Inlet/ Sump The inlets shall be inspected to ensure they have adequate sump capacity, the grate is in place, secure and free of debris, the frame and grate are not damaged, and internal concrete and grout is intact.  Inspect the inlets four times per year and following large storm events.  Clean sumps annually or whenever sumps become filled with sediment to half its depth (1’-0”).  Estimated Cost: $500 If inspection indicates the presence of petroleum, the petroleum material shall be removed and disposed of immediately in accordance with applicable regulations. Storm Drain Inlet Expected Design Life: If regular maintenance is performed, the storm drain inlet can be expected to last for 50 to 100 years. Expected Replacement Cost: $5,000 Underground Retention System (Stormtech Chambers): All storm drain pipe shall be inspected for any damage and/or blockages.  Inspect piping annually and following large storm events.  If excessive sediment is determined to exist in the pipe, it shall be removed through jetting and flushing.  Estimated cost: $1,000  After major storm events, monitor the system to ensure the runoff is infiltrating into the ground and completely draining within 72 hours after cessation of the storm. If the systems appear to be clogged, consult with an engineer or other qualified professional to evaluate the system and determine whether it needs to be replaced. If the retention system becomes clogged, the entire system must be replaced. Regular maintenance and sedimentation prevention greatly increases the life of the system. Underground Retention Expected Design Life: 50+ years if regular maintenance is performed. Expected Replacement Cost: $20,000 to $30,000 Velocity Carwash Storm Water Operation & Maintenance Manual 3 Housekeeping Operations Good housekeeping and material management reduces the risk of spills or other accidental exposure of materials and substances to storm water runoff.  All materials stored on-site must be stored in a neat, orderly manner in their appropriate containers and, if possible, under a roof or other enclosure.  Products shall be kept in their original containers with the original manufacturer’s label.  Substances should not be mixed with one another unless recommended by the manufacturer.  Whenever possible, all of a product will be used up before disposing of a container.  Original materials labels and material safety data sheets (MSDS) shall be kept by the Owner.  Petroleum products:  All on-site vehicles and parking areas shall be monitored weekly for leaks and spills.
