BMP Maintenance Information Purpose and Specific Narrative Urban Stormwater runoff contains many types and forms of pollutants. When compared to stormwater run-off from pre-developed conditions, high concentrations and some contaminates that are not naturally present in surface runoff from undeveloped local lands are found. Runoff from undeveloped watersheds contains sediment particles, oxygen-demanding compounds, nutrients, metals, 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. Best management practices (BMP’s), both structural and non-structural, can reduce the pollutants in stormwater. The BMPs proposed for this development are an infiltration basin and a woodland preservation area. An infiltration basin is a surface pond which captures first-flush stormwater and treats it by allowing it to percolate into the ground and through permeable soils. As the stormwater percolates into the ground, physical, chemical, and biological processes occur which remove both sediments and soluble pollutants. Pollutants are trapped in the upper layers of the soil, and the water is then released to groundwater. Inspections Responsibilities: Stormwater quality facilities shall be maintained in good condition, in accordance with the Operation and Maintenance procedures and schedules listed in the Indiana Stormwater Quality Manual or the City of Carmel Stormwater Technical Standards Manual, and the terms and conditions of the approved stormwater permit, and shall not be subsequently altered, revised, or replaced except in accordance with the approved stormwater permit, or in accordance with approved amendments or revisions in the permit. Following construction completion, inspection and maintenance of stormwater quality facilities shall be the long-term responsibility of the Owner. The City of Carmel Engineering department has the authority to perform long- term, post-construction inspection of all public or privately owned stormwater quality facilities. The inspections will follow the Operation and Maintenance procedures included in the City of Carmel Stormwater Technical Standards Manual and/or permit application for each specific BMP. The inspection will cover physical conditions, available water quality storage capacity and the operational condition of key facility elements. Noted deficiencies and recommended corrective action will be included in an inspection report. The Owner shall submit an annual BMP Maintenance Report 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 inspections, 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. This report should be submitted to: Carmel Engineering Department Attn: Stormwater Administrator One Civic Square Carmel, IN 46032 Infiltration Basin Maintenance Responsibilities: Routine Maintenance: The BMP owner will also be required to perform any maintenance specified at the City’s discretion. The following criteria shall be considered the minimum routine maintenance to be performed: 1. The detention area and drainage inlet/outlet structures should be kept free of debris and litter. 2. Removal of invasive vegetation from all side slopes. Chemical lawn treatment should be avoided near the basin embankments. Maintenance will also be required to repair erosion (if present) in the infiltration basin area. 3. Removal of sediment accumulation from the infiltration basin. Infiltration basin sediment removal should occur when sediment depths reach 1 inch. 4. Removal of woody vegetation from the embankment. Remedial Maintenance: Remedial maintenance shall occur whenever deemed necessary either by the BMP owner or the City of Carmel Engineering Department. Statements and Responsibilities The City of Carmel Engineering Department representatives have the right to enter the property and inspect the BMP at their discretion. The BMP owner is responsible for all maintenance and maintenance costs as outlined in Chapter 7 of the City of Carmel Stormwater Technical Standards.

Actions to be Taken: _____________________________________________________________________________ Stream Buffer Maintenance Responsibilities: Routine Maintenance: The BMP owner will also be required to perform any maintenance specified at the City’s discretion. The following criteria shall be considered the minimum routine maintenance to be performed: 1. Inspect stream buffer for clogging and excessive debris and sediment accumulation; remove sediment during dry periods. 2. Stream buffer should be inspected for erosion, scour, and unwanted growth. This should be removed with minimum disruption to the planting soil bed and remaining vegetation. 3. Stream buffer signage shall be inspected and repaired or replaced if damaged. 4. Disturbance to stream buffer should be minimal during maintenance. At no time should any vehicle be driven within the stream buffer. In addition, foot traffic should be kept to a minimum. Remedial Maintenance: Remedial maintenance shall occur whenever deemed necessary either by the BMP owner or the City of Carmel Engineering Department. Statements and Responsibilities The City of Carmel Engineering Department representatives have the right to enter the property and inspect the BMP at their discretion. The BMP owner is responsible for all maintenance and maintenance costs as outlined in Chapter 7 of the City of Carmel Stormwater Technical Standards.
