Checklists and Maintenance Activities  Stormtech Isolator Row Plus  Catch Basin Structure  Stormwater Infrastructure PROJECT NARRATIVE Operation and Maintenance Manual Prepared For: Memory Care Group Home Carmel, Indiana Project #W20-0317 Project Narrative Central IN Properties, LLC is proposing to develop multi-unit residential structure to be known as Memory Care Group Home on a 0.71 acre vacant parcel in Carmel, IN. Said parcel is Lot 1 of the 1800 106th Street Subdivision. The site is located north of 106th Street and between Towne Road and Ditch Road in Carmel, Indiana. Refer to Figure 1.1. The proposed development is on a site at a Latitude of N 39° 56' 30" and Longitude W 86° 11' 54", falling within Clay Township. The site is generally located in the Southeast Quarter of Section 4, Township 17 North, and Range 3 East in Hamilton County, Indiana. The stormwater runoff will be routed to two (2) sumped storm sewer inlets and an Isolator Row in the underground detention system to meet the Water Quality Requirements described in Chapter 700 of the Stormwater Manual. This O&M manual is for the inspection and maintenance of the Isolator Row, BMP sump structures, and stormwater infrastructures associated with Memory Care Group Home. Refer to Figure 2.

BMP Owner: The owner of the BMPs is typically the Homeowner Association. The BMP owner may also be the lessee of the property in the case of long-term leases of commercial and industrial zoned properties. The lessee is considered the BMP owner only if the lease specifically states that construction by the lessee must meet applicable local codes and regulations. Underground Detention: An Underground Detention facility removes sediment, biochemical oxygen demand (BOD), organic nutrients, and trace metals from stormwater runoff. This is accomplished by slowing down stormwater using an Isolator Row and forcing the runoff to filter through a stone base prior to leaving the system. Best Management Practice (BMP) Urban stormwater runoff contains many types and forms of pollutants. When compared to stormwater run-off from pre-developed conditions, high concentrations of some contaminants that are not naturally present in surface runoff from undeveloped local lands are found. Runoff from undeveloped watersheds contains metals, nutrients, sediment particles, oxygen-demanding compounds, and other constituents. Once developed, constituent loads increase because surface runoff volumes increase and the sources of many of these pollutants also increase. Supplemental applications of compounds, such as fertilizers, also tend to increase the availability of some pollutants to stormwater runoff. Runoff water quality in urban areas can be extremely detrimental to local habitat. Paved surfaces and standing water bodies for stormwater management control elevate the temperature of water entering streams. Chemicals in standing water and ponds are oxidized, resulting in depressed levels of dissolved oxygen. Increased runoff volumes and rates create scour and deposition damage to instream habitat. Activities in urbanized areas, such as vehicular traffic, deposit pollutants such as heavy metals and oil & grease on paved surfaces where they easily wash off into the streams. Best management practices (BMPs), both structural and non-structural, can reduce the amount of pollutants in stormwater. Stormwater Infrastructure: Storm water infrastructure and structures refers to structural or non-structural measures designed for the benefit of storm water conveyance. Storm water is the rainfall/ snowmelt that flows over our yards, streets, parking lots, and buildings and either enters the storm drain system or runs directly into a lake or stream. Owners of storm water infrastructure and structures are typically the property owner. The storm water infrastructure owner may also be the lessee of the property in the case of long-term leases of commercial and industrial zoned properties. The lessee is considered the owner only if the lease specifically states that construction by the lessee must meet applicable local codes and regulations Catch basins: Catch basin/inlet cleaning and repair has traditionally been performed to respond to localized flooding problems in streets. Catch basins are inlets at the curb with a small trap (usually six inches to one foot deep) below the sewer pipe. These devices help to clean storm water because particles in street runoff settle into the trap before the water enters the storm sewers. Catch basins require regular cleaning of the sediment trap to be. The inlets do not trap sediments and don’t need cleaning unless they are plugged. Cleaning for either catch basins or inlets can be done by hand (e.g., with a clamshell or shovel) or with a vacuum truck. Conveyance Storm Pipes: A good rule of thumb is to conduct inspection of storm drain inlets, ditches, channels, ponds and other treatment facilities at least once a year, prior to the beginning of the rainy season. Complete inspections early enough so that repairs can be made during dry weather. Catch basins should be inspected at least once every six months. Some storm water treatment devices, such as oil/water separators, may require more frequent inspection. For these, check the manufacturer’s specification or other design guidance handbooks. Sewer pipes and culverts should be inspected every three to five years, or in response to a reported problem. Most agencies inspect their sewer pipes six inches or larger with a TV camera, and pipes 36 inches or larger with a walk-through inspection. All other parts of the system are inspected visually. Look for excessive silt build-up, erosion, unusual algal growth, cracked or collapsed pipes, misaligned joints, and other signs of problems such as a sheen on the water surface, discolored water, or an unpleasant odor. Check with product manufacturers or storm water handbooks for advice on what to look for when inspecting more sophisticated treatment devices such as flow splitters and diverters. When a problem is noted, take steps to correct the problem, or route this information immediately to the appropriate individual(s) in your organization who can respond. If needed, develop a good response plan to ensure quick follow-up in the future. Sump Structure: A sump is a standard catch basin or manhole constructed with part of the structure located below the outlet, creating a permanent pool of water in the bottom of the structure. The sumps allow for sediment and debris to settle out of the water flowing through the structures. Catch basins and manholes are not made for pretreatment of storm water; however, they can potentially function as pretreatment structures when the bottom of the structure is significantly below the invert of the outlet pipe. Similar to the proprietary hydrodynamic devices, standard catch basins and manholes with deep sumps have a smaller footprint than an underground storage structure. Sumps are generally less expensive and more readily available than the hydrodynamic separators. INSPECTION Inspections The first inspection shall be performed immediately after construction is completed. If there are any deficiencies are found during the inspection, these should be addressed in a timely manner. Requirements regarding the submittal of annual inspection reports to the 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. Construction Completion Type of Inspection Inspection Due Date Subsequent Due Dates Date: Storm Structures 1 year after construction completion date After every rain event >1 inch over a 24 hour period Annually, within same month as initial report Date: Isolator Row 1 year after construction completion date After every rain event >1 inch over a 24 hour period Annually, within same month as initial report Routine inspections are the responsibility of the BMP owner. Maintenance is also the responsibility of the owner. The BMP owner shall be financially responsible for any maintenance or repairs required by the City or its representatives during the City’s inspections. The approval maintenance plan and inspection forms provided with this manual should be used as guidance for performing maintenance activities. Completed inspection forms must be maintained by the BMP owner and produced upon request by the City. The City must be notified of any changes in BMP ownership, major repairs or BMP failure in writing within 30 days. The letter should be addressed to: City of Carmel Carmel Engineering Department Storm Water One Civic Square Carmel, IN 46032 The City and/or its representatives have the right to enter the property to inspect BMPs. In the event that the City finds a BMP in need of maintenance or repair, the City will notify the BMP owner of the necessary maintenance or repairs and give the landowner a timeframe for completing the maintenance or repairs. If the maintenance or repairs are not completed within the designated timeframe, the City shall perform the maintenance or repairs and bill the landowner for the actual costs for the work. Inspection & Maintenance Activities Refer to the checklist provided with this manual for operation, maintenance and inspection of BMP and storm water infrastructure. The checklist is for the use of the BMP owner in performing routine inspections. The developer/owner is responsible for the cost of maintenance. The BMP owner must maintain and update the BMP operations and maintenance plan. At a minimum, the operations and maintenance plan must include, but is not limited to: 1. Visual inspection and removal of debris from all storm structures including the sumped structures and Snout Guards. BMP owners must routinely inspect BMPs to verify that all BMP components are functioning as designed and are not in danger of failing. All BMPs need maintenance to function as water quality and quantity enhancements. Maintenance can range from dredging sediment out of the treatment area to mowing grass. The BMP owner agrees to the maintenance and inspection programs attached with this manual. Inspections must be documented on the inspection forms included in this Operation and Maintenance Manual. A self-monitoring program by the project site owner is required during construction and during a maintenance schedule of any project described. A trained individual employed or retained by the project site owner shall prepare and maintain a written evaluation of the project site by the end of the next business day following each measurable Inspection. Inspection during construction should be after a storm event and at a minimum, one (1) time a week.
