About the BMP Stormwater management best management practices (BMPs) are control measures taken to mitigate changes to both quantity and quality of urban runoff caused through changes to land use. BMPs are designed to reduce stormwater volume, peak flows, and/or source pollution through a variety of methods, including but not limited to, evapotranspiration, infiltration, detention, and filtration. B. Contact Information for the BMP Owner i. Nigel Downton ii. Address: 240 N. Meridian St., Room 120, Indianapolis, IN 46204 iii. Phone: (217) 265-4403 iv. Email: nd2147@att.com C. BMP Owner Acknowledgement Agreement See Appendix A. D. Right-of-Entry Statement Allows the City of Carmel to inspect and maintain the BMP structure as necessary. See Appendix B. E. BMP Description & Operation Detention basins temporarily store a portion of stormwater runoff following a storm event. They normally do not have a permanent water pool between storm events. The objective of these systems is to remove particulate pollutants and to reduce maximum runoff values associated with development to their pre-development levels. The detention basin for this project will include soil stabilization through geotextile erosion blankets and permanent vegetation. Required maintenance includes keeping the basin clear of debris, removing accumulated sediment in the sediment forebay every few years, and protecting the side slopes from soil erosion. Rip-rap will be included at all inlets and outlets of the detention basin to prevent erosion at the bottom of the flared-end sections. Additionally, a restrictor will be implemented in the 8” RCP outlet pipe to reduce the flow rate and velocity of the stormwater leaving the site. Lastly, a drainage swale will be placed in the northeast end of the site to covey water to the detention basin. The drainage swale will be constructed during grading operations. Maintenance includes keeping the swale clear of debris and accumulated sediment that impedes the stormwater conveyance. F. Maintenance Requirements 3 i.

Inspection Reports The first inspection 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 with the City. See appendix E for inspection form. A written yearly inspection report must be submitted to: City Hall – Department of Engineering Attn: Stormwater administrator One Civic Square Carmel, IN 46032 4 APPENDIX A: BMP Owner Acknowledgement Agreement Owner Acknowledgement Agreement (“Agreement”) For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned owner (“Owner”) hereby submits this Operation and Maintenance Manual (“Manual”) to the City of Carmel, Indiana (“City”) as a written acknowledgement of Owner’s warranty and agreement to institute, maintain, and follow the water quality Best Management Practices (“BMPs”) listed below, and to follow and abide by the inspection schedule and maintenance activities listed in this Manual.
