Please refer to Figure 1. The proposed development is on a site at a Latitude of N 39° 59' 51" and Longitude W 86° 13' 29", falling within Washington Township. The site is generally located in the Northeast Quarter of Section 19, Township 18 North, and Range 3 East, Clay Township, Hamilton County Indiana. The proposed Horse Barn and Riding Center will utilize a combination of BMP features to meet the standards for Water Quality as defined in Chapter 700 of the City of Carmel’s Stormwater Technical Standards Manual. These features were sized using the methodology described in said manual. Refer to Figure 2 for the location of the following BMP features for said development: • Conveyance Stormwater Infrastructure • Vegetated Swale(s) • Wet-Detention Basin w/ Forebays • Emergency Spillway/Overflow • Low Flow Outlet Control Structure BMP Owner Contact Information: Joel Westfall 6215 S.

Urban stormwater runoff contains many types and forms of pollutants. When compared to stormwater run-off from pre-developed conditions, high concentrations and 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. BMP Owner: The owner of the BMP, typically the property owner. 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. 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. 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 are more readily available than the hydrodynamic separators. Snout: This is the most basic application. This system combines a sumped catch basin with a hood. It is useful for capturing trash and floatables, and modest levels of free oils, and O&M Manual: 6 of 27 4/21/2016 sediment. These structures can be inlet-only, or in-line with other structures. To increase oil retention, oil absorbent booms can be placed in the structure. This application has limitations based primarily on the volume and sump depth of the structure itself. To minimize resuspension of finer captured solids, a deep sump, with a minimum depth of 4 feet, or a depth equal to 3X the outlet pipe inside diameter is recommended. 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 Inlets: Inlet cleaning and repair has traditionally been performed to respond to localized flooding problems in streets. The inlets do not trap sediments and don’t need cleaning unless they are plugged. Cleaning for 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 and other drainage 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. Storm Pipes should be inspected every three to five years, or in response to a problem. Most agencies inspect their sewer pipes six inches or larger with a TV camera. 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. 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. Swales: Swales are open, shallow channels with vegetation covering the side slopes and bottom that collect and slowly convey runoff flow to downstream discharge points. Swales can O&M Manual: 7 of 27 4/21/2016 serve as part of a stormwater drainage system and can replace curbs, gutters and storm sewer systems. Mechanical Water Quality Unit: The mechanical water quality unit provides a highly effective means for the removal of sediment, floating debris and free-oil. Swirl technology, or vortex separation, is a proven form of treatment utilized in the stormwater industry to accelerate gravitational separation. The WQU provides treatment for most contaminated first flush, while the cleaner peak storm flow is diverted and channeled through the main conveyance pipe. A combination of gravitational and hydrodynamic drag forces encourages the solids to drop out of the flow and migrate to the center of the chamber where velocities are the lowest. 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. O&M Manual: 8 of 27 4/21/2016 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 City will perform annual inspections of BMPs, using similar checklist. 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 inspect and removal of debris from inlet, outlet, and sump structures 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. Inspection during the maintenance schedule must routinely inspect all storm water infrastructures to verify that all components are functioning as designed and are not in danger of failing. They should be inspected a minimum of an annual basis or upon observed failure.
