The development will be called Old Meridian & Main. The proposed development will include apartments, a parking garage, associated utility infrastructure, and a StormTrap underground detention facility. Adjoining Land Conditions North: Existing Commercial & Residential South: Carmel Middle School Athletic Fields East: Existing Commercial West: Existing Commercial Soil Types For the area of the site being developed, soils maps from the United States Department of Agriculture Soil Conservation Service identified 71% of Type C Soils, and 29% Type B Soils located on site. Crosby, Brookston, and Miami soils were all found on site. For the purposes of calculating developed basin curve numbers, the hydrologic soil groups will be bumped up to the next lower infiltrating group where development is taking place. Existing Conditions The existing site is currently a developed commercial lot with a total site area of approximately 6 acres. The site generally slopes from the northeast to the southwest, and into existing storm sewer infrastructure. There are no floodplains on or near the site. The detention facility was designed to detain the post-developed 100-year storm and release the runoff at the pre-developed 10-year peak storm release rate. Likewise, the post-developed 10-year peak storm shall be detained and released at the pre-developed 2-year peak storm release rate. Based on these requirements and the existing acreage, the allowable release rates have been calculated as follows: Discharge Point Area (Ac.) 10-YR Allowable Flow (cfs) 100-YR Allowable Flow (cfs) OUTLET 5.59 11.06 14.66 Results from the Existing ICPR model can be found in Appendix C of this report, along with the Existing Basin Map and Existing Basin Calculations. Proposed Detention Stormwater runoff will be detained using a StormTrap underground detention chamber system located underneath the parking garage in the northeast corner of the site. The underground detention facility was designed to detain the post developed 100-year storm and release the runoff at the pre-developed 10- year peak storm release rate, and to detain the post-developed 10-year storm and release the runoff at the pre-developed 2-year peak storm release rate. The outlet control structure was designed with 2 orifices, which consist of an 18” diameter orifice at the invert of the underground detention facility, and a 24” x 36” rectangular orifice located two feet above the lower orifice. Results for the ICPR simulation can be found in Appendix D of this report, along with the Proposed Basin Map and the Proposed Basin Calculations. A summary of the proposed peak release rates vs. allowable is as follows (from ICPR model in Appendix D) Storm Event Allowable Release Rate (cfs) Proposed Release Rate (cfs) 10 -Year 11.06 7.20 100 - Year 14.66 11.14 Storm Sewer Design The storm sewers have been designed using the rational method for a 10-year storm event. These calculations can be found in Appendix E of this report. Inlet capacity calculations have also been provided for the new structures in Appendix E. Water Quality The primary post-construction water quality measures for the Old Meridian & Main development include one (1) Stormwater Quality Unit (Aqua-Swirl Structure) and one (1) StormTrap Underground Detention Facility. The Aqua-Swirl was sized for an 80% TSS Removal Rate. Water Quality Calculations can be found in Appendix F of this report. Secondary treatment measures include gras filter strips, swales, permanent seeding, and landscape plantings.

The third letter is a capital letter and indicates the class of slope. Symbols without a slope letter are for miscellaneous areas, Udorthents, or nearly level soils. Some symbols have a number at the end and are eroded phases. A final number of 2 indicates that the soil is moderately eroded, and a number 3 indicates that the soil is severely eroded. 0 500 1,000 1,500Graphic Scale (Feet) 1 inch = 1,000 feet N MERIDIAN STW C
