In order to maintain water quality within the BMP, light maintenance activities will be needed to manipulate hydrology. This document defines responsibilities for operating, inspecting and maintaining the stormwater system at the Singh Subdivision. 3.0 STORMWATER & DETENTION MAINTENANCE Storm sewer pipes, detention pond, and outlet control weir structure should be regularly maintained and cleaned of debris. All piping should be inspected monthly and after each rainfall event, especially during the autumn season. Outlet control structures 402 & 432 should be inspected more regularly when falling leaves are present. Refer to Appendix B for Maintenance Map and Details. Sample inspection logs are included in Appendix C. Disposal of all sediment must be in accordance with all federal, state and local requirements. Additionally, Lakhwant and Mike Singh will perform annual compliance inspections of all permanent BMPs. -2- Singh Subdivision September 2021 4.0 WATER QUALITY SYSTEM MAINTENANCE The City of Carmel reserves the right to enter the property at any time to inspect the operation of any Best Management Practices (BMP) onsite. The following is a description of the BMPs in the Singh Subdivision: · Dry Pond: Per the Indiana Stormwater Quality Manual “Dry extended detention basins, when carefully planned and constructed, are applicable in a wide variety of situations. The flexibility of basin design makes this measure one of the more versatile storm water management measures. Dry extended detention basins should not be considered the final solution for pollutant removal. These structures have limited effectiveness for pollutant removal. The pollutants that are associated with runoff from the drainage area should be evaluated and considered when selecting and designing a measure. This will be particularly critical if the drainage area includes storm water hotspots. Therefore, consideration should be given to pretreatment storm water quality measures or alternative measures should be selected in place of dry detention that will meet the objectives for pollutant removal.” See Appendix B for the location and details of all infrastructure and water quality BMPs. 4.1 WATER QUALITY DEVICES INSPECTIONS The BMPs require certain items to be inspected on a monthly or annual basis during the existence of the BMPs. This inspection is the responsibility of Lakhwant and Mike Singh. More frequent inspections may need to take place during periods of heavy rainfall. For each drainage system listed below, the following details shall be inspected monthly and after major rainfall events (>1 inch in 24 hours). Also refer to sample inspection logs in Appendix D. · Underdrains– Remove all debris to ensure openings are clear and operating properly. Cleanouts (C.O.) at the end of underdrain pipes should be utilized for debris removal. Water and sediment from cleaning procedures should NOT be dumped into a sanitary sewer. · Inlets and outlets (piping) – Remove all debris to ensure openings are clear and operating properly. The maximum sediment depth should be no more than ¼ of the pipe diameter and up to a maximum depth of 6”. Check for rip rap stone displacement and erosion of the apron surrounding pipe end section. Repair immediate failure. Water and sediment from cleaning procedures should NOT be dumped into a sanitary sewer. · BMP Dry Pond – -3- Singh Subdivision September 2021 o Vegetation & forebays – This area includes all turf vegetation within the boundary of the BMPs. Some species of plants are considered invasive and should be eradicated. Species such as reed canary grass (Phalaris arundinacea), purple loosestrife (Lythrum salicaria), common reed (Phragmites australis), and cattails (Typha spp.) would be considered fast colonizing and invasive species. Remove as necessary. o Pipes – attempt to clear by flushing with water or by pipe cleaner rods o Outlet Orifices – keep screens clean, vegetation away from outlet, watch for excessive discharge of silt or sand. o Rip Rap Erosion Protection – Check for displacement of riprap material, filter fabric, slumping, and erosion along the edges, especially on the down-slope side o This area includes all turf vegetation within the boundary of the BMPs. Some species of plants are considered invasive and should be eradicated. Species such as reed canary grass (Phalaris arundinacea), purple loosestrife (Lythrum salicaria), common reed (Phragmites australis), and cattails (Typha spp.) would be considered fast colonizing and invasive species. Remove as necessary. See desired planting list & schedule in Appendix C. A protective cover of vegetation shall be established on all exposed surfaces of the pond embankment, spillway, borrow and spoil areas and to a minimum of 50 feet on all sides of pond and 100 feet upstream of the pool area. Open areas to be vegetated will be limed, fertilized, seeded and mulched according to the construction specification. No woody vegetation shall be planted on or within 25 feet of the pond embankment or spillway. See Appendix B for the location and details of all infrastructure and water quality BMPs. If these maintenance guidelines are not followed, the BMPs may fail to attain water quality objectives set forth in the regulations. The BMP shall be owned by the developer/property owner; any and all maintenance and repair activities shall be paid for by the owner. Documentation of all repairs should be kept on file by the owner for review by City of Carmel inspectors. Sample inspection logs are included in Appendix C. Right of Entry - The City of Carmel may inspect the premises at any time necessary to determine the functionality of any BMPs onsite. City of Carmel Note- The BMPs shall be owned by the developer/property owner; any and all maintenance and repair activities shall be paid for by Lakhwant and Mike Singh. The requirements of the O&M Manual shall remain in effect regardless of change in ownership of the development. Furthermore, it shall be the responsibility of the BMP owner to provide the O&M Manual to future -4- Singh Subdivision September 2021 parties who will assume responsibility for the operation and maintenance of the post-construction storm water quality measures. Lakhwant and Mike Singh will perform annual compliance inspections of all onsite BMPs and provide the reports to City of Carmel Engineering Department. The first report is due one year after construction is completed, with subsequent reports due each year within the same month of the initial report. If there are any deficiencies found during the inspection, these should be addressed. If the inspection report is not received within the month it is due, if there are deficiencies which were not included in the report, or if any deficiencies included in the report are not addressed in a timely manner, the BMP owner faces enforcement action from the City. Refer to Agreement in Appendix A. 5.0 SUMMARY The objective of the operation and maintenance manual is to allow the owner of the storm management system to manage the system to the City of Carmel specifications. The City requires minimal information for their records: 1. Maintenance agreement. The agreement requires the owner to comply with the maintenance set forth in the manual. 2. Monthly and annual data sheets and repair documentation must be kept on site for the City Inspectors to review during their annual inspection of the site.

Clean air filters, new fuel, oil & filter change, perhaps tune-up, etc. · Check on supplies of materials such as fertilizer, herbicide, garden equipment, etc. March/April/May · Cut down and remove dead leaves, stems and seed heads from perennials and grasses. · Mulch where needed to reduce weeding and maintain moisture. · Plant trees, shrubs, vines, perennials and grasses through May. Recycle all plastic pots. · Prune winter-damaged branches on shrubs or trees that have not begun to grow by late April/early May. · In late April and early May cut back tall grasses by 50% to promote fuller and more compact growth. · Water new transplants and newly planted shrubs and trees unless rainfall is abundant. June/July/August · Vigorous, unwanted limbs should be removed or shortened on new trees. · Cultivate and mulch. Mulching will reduce about 70% of the summer yard maintenance. · Remove diseased plant material by digging entire plant and disposing in trash. Composting will spread the virus. · Water all key planting areas thoroughly unless rainfall has been adequate. · Trim back any groundcover overhanging curbs or sidewalks. September/October · Check plants for signs of water stress, nutrient deficiency or disease. Fertilize only when necessary. · Mulch where needed to reduce weeding and maintain moisture and protect from winter freezing and drought. · September and October are best months to kill invasive species. Cut and spray stumps with 10% glyphosate. Properly dispose of cuttings if they contain berries to prevent spreading the seeds and reinfesting the newly cleared area. · Trim back any groundcover overhanging curbs or sidewalks. November/December · Continue to seek out and remove invasive species. · Clean tree leaves and debris out gutters after tree leaves have fallen. · Winterize hoses and outside water sources. Clean out rain barrels. Add fuel stabilizer to engines before winter storage. Drain and store water hoses. Clean up all tools. · Review the year’s schedule and make plans for next year’s improvements.
