Agriculture and urban development are the two major types of land - disturbing activities in Indiana. Both are very important to the economic well being of the citizens of the state. Without proper planning and the wise selection of storm water management measures, these areas of soil disturbance are very vulnerable to accelerated erosion and sedimentation. Whenever vegetation is removed from the land's surface, the soil becomes exposed to the erosive effects of wind and water. Although erosion is a natural process, it can be greatly accelerated by human action that disturbs the land's surface. While it is true that the tons of soil eroded on agricultural lands is much greater, it has been proven that the amount of soil eroded on a per -acre basis can be many times greater on active construction sites. The loss of soil through erosion commonly results in the loss of good topsoil and the associated minerals and nutrients required for plant establishment and growth. Soil erosion not only causes on -site damage problems, but can also negatively impact water quality downstream through sediment pollution. It has been shown that sediment is the number one water quality pollutant by volume in Indiana. Sediment damage can take many forms. Sediment accumulation in wetlands can reduce their capacity to retain storm water and its value to wildlife. Sediment deposition in storm sewers can reduce their efficiency and capacity. Sediment and accompanying nutrients often reaches lakes and leads to algal blooms, a decrease in lake depth, and a decrease in the recreational and aesthetic value of the lake. In addition to erosion and sediment damage, the building of residential subdivisions, shopping centers, industrial parks, schools, recreational attractions, etc. can have a significant effect on the patterns and amounts of storm water runoff during and after construction takes place. This often leads to water quality degradation and more frequent flooding events. The final land use associated with many projects will also contribute to the discharge of pollutants. These pollutants will typically be generated by the activities that are associated with the final land use. It is important to practice effective storm water management and treatment of storm water runoff before, during, and after construction. Otherwise, the landowner and /or public may end up paying more for project reconstruction and replacement /maintenance of existing infrastructure. Furthermore, public environmental awareness demands that land users work with nature, and not against it, to protect Indiana's land and water resources. There are many ways to minimize the impacts of urbanization and protect the integrity of Indiana's natural resources. One method is through careful planning and inclusion of proven storm water management measures in a project's construction and development plans. Careful planning can prevent or at the very least alleviate much of the damage caused by erosion and sedimentation and the pollutants that will be associated with the final land use. However, careful planning and incorporation of appropriate storm water quality measures into a project's construction plans is not enough. These measures must be deployed and maintained on the site throughout all construction phases. (Indiana Storm Water Quality Manual, 2007) This manual provides engineers, developers, builders, contractors, government officials, and other with guidance on the inspection and maintenance of installed post - construction storm water quality measures for The Legacy Towns & Flats, Phase II. STORM WATER QUALITY CONTROL REQUIREMENTS BMP OWNER CONTACT INFORMATION J.C. Hart 805 City Center Drive, Suite 120 Carmel, Indiana 46032 Contact Person: Todd May Phone: (317) 573 -4820 The project site owner must submit to the City of Carmel a Storm Water Pollution Prevention Plan (SWPPP) that would show the placement of appropriate BMP(s) specified in the City of Carmel Stormwater Technical Standards Manual. The noted BMP(s) must be designed, constructed, and maintained according to guidelines provided or referenced in the City of Carmel Stormwater Technical Standards Manual. It is the policy of the City of Carmel that the water quality management program be performance - based. To that end, a best management practice (BMP) approved for use in the City of Carmel will be capable of meeting or exceeding the 80% removal target for TSS whether the control be a single structure or a series of controls. In addition to TSS removal, a BMP must also be designed to store and treat the water quality volume (WQv). The water quality volume is the storage needed to capture and treat the runoff from the first inch of rainfall. INSPECTION AND MAINTENANCE It is essential that any approved BMP be properly inspected and maintained in order to assure the TSS removal performance. Therefore, an inspection and maintenance plan is required. The county encourages the use of a high- efficiency, low maintenance BMP(s) that has the potential for removal of multiple storm water pollutants. The City of Carmel and /or its representatives will perform annual inspections of permanent BIvIP(s) to ensure compliance. Routine monthly and annual inspections are the responsibility of the BMP owner. The BMP owner shall be financially responsible for any maintenance or repairs required by the City of Carmel and /or its representatives during the City of Carmel's inspections. The City of Cannel and /or its representatives have the right to enter the property to inspect the BIvIP(s). In the event that the City of Carmel finds a BMP in need of maintenance or repair, the City of Carmel will notify the BMP owner of the necessary maintenance or repairs and give the BMP owner a tuneframe for completing the maintenance or repairs. If the maintenance or repairs are not completed within the designated timeframe, the City of Carmel shall perform the maintenance or repairs and bill the BMP owner for the actual costs for the work. Annual inspection reports are required to be submitted to the City of Carmel Engineering Department, Attn: Storm Water Administrator, One Civic Square, Carmel, IN 46032. 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 of Carmel.

The sump catch basins are storm structures constructed with a sump which serves as a sediment storage basin that can be accessed and cleaned out when necessary. INSPECTION & MAINTENANCE ACTIVITIES The performance of a sump catch basin is highly dependant on the inspection and maintenance of the structure. If the structure is not properly maintained, the ability to remove pollutants will decrease. The BMP owner will need to provide the maintenance for the sediment removal. The BMP owner agrees to the following monthly inspection program: 1. Remove manhole lid or open pavement grate to expose inside of box structure. 2. Lower a dip stick equipped with a ball valve (Sludge Judge or similar device) into opened box structure. 3. Measure the depth of sedimentation. The level of sedimentation shall not exceed 12 inches before maintenance. 4. In the event that maintenance is required, call a local vactor company to remove sediments and other debris with a vacuum truck. Dispose of all waste in accordance with the City of Carmel and any applicable state, and /or federal requirements.

The proposed BMPs intend to provide natural and sustainable water quality improvement, passive recreation, and natural habitats to support wildlife and native plants. In order to maintain water quality and vegetative health within the BMPs, inspection and Tight maintenance activities will be needed. An 1 1x17 BiM location map has been included at the end of this Manual. D,?_ VEGETATED SWALE. RAM The vegetated swale BMPs Were designed to incorporate natural and sustainable water quality improvements into an aesthetically pleasing site landscaping feature. The planting and seeding plans were developed with the goal of providing a diverse, native plant community extending from the bottom of (he basin elevations to the lop of the finished grade. Although the BMPs are expected to develop into dynamic ecosystems that will eventually require little vegetation maintenance, the following inspection, monitoring and maintenance schedule was developed to ensure that the BMPs are properly installed and are developing in accordance vrith intended design goals. D.3 Monthly Inspections Town of Carmel as well as Hamilton County personnel will have the right to enter the premises to perform compliance inspections of all permanent BMPs. However, routine monthly and annual inspection F monitoring of the BMPs are the responsibility of the owner. Sample monthly inspection logs are included in at the end of this Appendix. The following areas should be inspected on a monthly basis for the first two years after conslruclion of the wetland: D.3.1 Vegetation • Vegetation cover should be greater than 85 %. • Vegetation should be healthy. o Vegetation species should be consistent with plans. • Some species of plants such as reed canary grass (Phalalis arundinacea), purple loosestrife (f_ylhuli salicaria), common reed (Phragmites australiis), and cattails (Typha spp.) are consicleied invasive and should be eradicated within one month of discovery. Invasive species wit( be docunientecf during the monthly inspections according to species, location and approximate percent cover. Photos of these species are included in Appendix E for reference. • Landscaped areas of the banks that are eroded or have exposed bare earth shall be restored to proper garde, stabilized and re- seeded with the appropriate seed mixtures. D.3.2 Pollutants O Remove all iloalable debris. • Remove visible pollution such as oily sheens, discoloration, and cloudy or muddy wafer. • If sediment accumulation is impairing flow of seam .eater into wet ponds, the sediments should be removed. D.3.3 Erosion O There should be no expcced earth on hanks. o Other evidence of erosion will be noted Areas of severe erosion or other conditions that may constitute a public hazard will be corrected as soon as possible and prior to the next monthly inspection. DA Annual Monitoring Annual monitoring :rill be performed for Three years after construction to document the development of the BMP. The following inforinallon will be collected as part of the annual monitoring. 4 A letter report will be issued that Includes monitoring forms, a summary of monthly inspections, and recommendations for routine or special maintenance activities. D.5 Maintenance Maintenance responsibilities shall remain in effect for the life of the Bf ?P front the date the construction is completed. If regular inspection and maintenance guidelines are not followed, the BMP may fail to attain water quality objectives set forth in the Town of Carmel regulations. D.5.1 Vegetation A species rich community of emergent ntacrophytes'rill be planted in the portions of the constructed wetland below the normal pool elevation. Although the constructed wetland 13MP is expected to develop into a dynamic ecosystem Thal will eventually require little or no vegetation maintenance, some vegetation maintenance will be required in the first 2 years following construction in order to give the new vegetation communities a chance to become ';ell established. O If the inspection and monitoring indicates the presence of invasive species, measures will need to be taken to prevent these species from establishing themselves at the new BMP. These species should be either physically removed or treated with herbicide by qualified native wetland plant maintenance professional. Physical removal is strongly preferred above the application of herbicide. If herbicide is used, application must be conducted in compliance with federal, state, and local laws and regulations. Replant or reseed vegetation when damaged, vandalized or removed, in compliance to original planting specifications. D.5.2 Debris U Debris shall be removed from the constructed wetland BMP in order to maintain a functioning and aesthetically pleasing landscape feature. D.5.3 Nuisance Animals • Burrowing mammals should be controlled or eradicated when present in densities that endanger the integrity of the embankment. Damage caused by their burrowing must be repaired as soon as possible. Any burrowing mammal control effort will need to be carefully planned and executed to avoid negative impacts on adjacent habitats and wildlife. Such measures will be confined to the embankment. Removal of burrowing mammals in other areas of the .vellancl may not be necessary. Mammals that may he of concern are beavers (Castor canadeensis). and muskrat (Ondafra z!b0fhrca • If animals are burrowing into the berm areas, then a certified wildlife damage control expert should be contacted to remove the beavers and /or (Tarn, and muskrats. o The dense wetland vegetation proposed would not be an altraati;e habitat for geese since they prefer open water and mowed vegetation. :2)12 Ltg.'j -.`rD.' %F.:n!a /;..'_i �2JSfCst:1 •arc'ir:erl " „_."'j City c!
