Project No. 2020-340 Project Narrative I. Project Location The proposed project is located at 5201 East Main Street, Carmel, Indiana. The site does not lie within a floodway or floodplain per FEMA panel 18057C0227G effective November 19, 2014. Refer to the Site Location Map and Flood Insurance Rate Map provided in Appendix A. II. Project Description The proposed site improvements will consist of a new parking lot addition, new concrete sidewalks, new restroom building and a new synthetic field for the varsity baseball field. Proposed stormwater infrastructure will include a field underdrain system, storm sewers and underground detention chambers. The existing east dry detention basin will be modified to maximize detention volume in the developed condition. This project will disturb approximately 8.5 acres. The Junior Varsity baseball field will remain largely undisturbed with the exception of a few low areas that will be filled with topsoil removed from other areas on site. IDEM Rule 5 NOI will be a water quality permit required for construction activities associate with this project site. III. Existing Drainage Conditions The project site consists of existing baseball playing fields and pervious lawn areas that mostly sheet drain in a northeasterly direction to the existing east dry detention basin. Approximately 0.58 acres of the project site (Varsity left field) drains to the existing west dry detention basin which is interconnected to the East Basin. Approximately 2.74 acres of the project site drains to the existing south basin. The remainder of the project site drains to the east basin. The site soils mainly consist of Ockley silt loam-Urban land complex and has a “B” hydrologic soil group rating, see Soil Map and related soil data in Appendix A. An Existing Drainage Conditions Exhibit is provided in Appendix B. Discharge from the site is an existing 24” RCP which is located on the north side of the existing east basin which is part of the Carmel School Arm of the Mitchner Legal Drain. An existing drainage report from the 1999 Facilities and Transportation Building Project has been provided in Appendix F. The drainage report for the original 1985 construction of the ESC and fields could not be located, however the construction documents have been included in Appendix F. The existing conditions model was recreated using ICPR4.07.06. The stage-storage table utilizes a recent topographic survey of the west and east basins. The basin information for the west basin was pulled from the existing drainage report. The east basin information was delineated per the recent topographic survey. The results of the model can be found below. In the existing condition model, the west basin overtops the top of bank in the 100-year storm, whereas in the previous report the 100-yr elevation was 778.88.

Proposed Storm Sewer Design The proposed storm sewer is designed to convey the 10-year stormwater runoff flows from the developed inlet basins. The storm sewer has been designed via the rational method in accordance with the City of Carmel Stormwater Technical Standards Manual. The Proposed Storm Sewer Exhibits, calculations, and pipe sizing are provided in Appendix C. V. Proposed Drainage Design The hydrologic soil group rating for the developed site has been changed from the initially determined group rating “B” to the next less infiltrating group rating “C”. The stormwater runoff from the project site will drain to the modified existing east basin via new storm sewer system and sheet flow. The project improvements will increase the total impervious area by approximately 0.9 acres. The varsity baseball field will have new synthetic turf that will include an underdrain drainage system that will drain to a new underground detention chamber facility and will discharge at a restricted release rate to the new storm sewer system. The new parking lot addition, grass area north of the varsity field, concrete walk and grass area south of the varsity field, southwest portion of the junior varsity field and concrete walk between both fields will also drain to the new storm sewer system. The majority of the existing junior varsity field will continue to sheet drain to the east basin. The outfall from the existing west basin will continue to drain to the east basin through the existing pipe underneath the parking lot. The east basin will be modified to maximize available storage and to store the additional runoff from the proposed project. In addition, approximately 2.74 acres of the south basin that currently drains offsite to Badger Field, will be diverted into the modified east basin to provide drainage relief in that area per a request from the City of Carmel. The east basin has been expanded by 1.6 ac-ft from 5.5 ac-ft to 7.1 ac-ft of storage. The synthetic turf field (East 4) is 3.16 acres with a time of concentration of 10 minutes and curve number of 98 (CN=98). Synthetic turf is modeled in ICPR with a CN of 98 to model the direct contribution of runoff to the underlying underdrains and underground storage, similar to the modeling of a wet pond. However, in reality, it is a highly permeable surface. Runoff from East 4 contributes to the underdrain and underground storage and is released at a controlled rate. Page 5 of 180 Carmel Clay Schools – Carmel High School Hartman Field Improvements May 12, 2021 TLF, Inc. Project No. 2020-340 The field underground detention has been designed such that the 10-yr post developed peak discharge rate is less than 0.1 cfs/acre and the 100-yr post developed peak discharge rate is less than 0.3 cfs/acre. In order to meet the 10-yr allowable discharge, an orifice size less than 6” in diameter is required. To account for this, two different model scenarios were completed to ensure that sufficient detention volume is provided. The first model (utilizing the sizing outlet control structure) was ran using the orifice sizes required to meet the allowable discharge rates. The second model orifices were increased to a 6” minimum diameter. The Educational Services Center has a future 3,000 sft building addition and sidewalk and path expansions. This future impervious area has been accounted for in the calculations for the East 3 and West curve numbers. The tables below indicate the results of ICPR models for each detention basin. Comparing the existing model to Model 2, the 100-yr elevation of the west basin decreases by 0.08 feet, the 100-yr elevation of the east basin increases by 0.09 feet, and the overall site discharge from the east basin decreases by 0.52 cfs.

This arm of the legal drain was built as part of the 1985 construction of the school for the existing runoff rates, which have been decreased as part of this project. Photographs of the site, surrounding area, and the downstream system and outlet into the Mitchner Drain have been included in Appendix G. Page 6 of 180 Carmel Clay Schools – Carmel High School Hartman Field Improvements May 12, 2021 TLF, Inc. Project No. 2020-340 VI. Proposed Water Quality Design The proposed site improvements will utilize a manufactured water quality device (Aqua- Swirl XC-7 CCW) to meet the water quality requirements of the 1-inch 24-hour event for the entire disturbed area of 8.5 acres using the City of Indianapolis Sizing Chart. This water quality unit will be installed on-line of the new 24” HDPE prior to discharge into the east basin, where the on-line maximum flow rate is not exceeded. The proposed improvements also includes a underground detention system with an isolator row for water quality treatment. The stormwater quality calculations can be found in Appendix E. VII. Summary and Conclusions The drainage from the proposed site has been designed in accordance with the City of Carmel Stormwater Technical Standards Manual limiting stormwater runoff from the site, therefore no adverse impacts are anticipated to affect adjacent or downstream landowners. This project will disturb approximately 8.5 acres of the overall site. Erosion control measures will be implemented before construction begins and maintained during construction to comply with IDEM Rule 5, Notice of Intent for Construction and Land Disturbance.

The Isolator Row is covered under US Patent No.: US 6,991,734 B1. 1.a. Description: The Isolator Row is a row or rows of StormTech thermoplastic chambers that are wrapped in filter fabric and installed below grade. Stormwater enters the chambers and must pass through the filter fabric media where sediments and other contaminants are filtered out as stormwater exits the Isolator Row through the fabric. Some of the unique features of the Isolator Row that contribute to its effectiveness and practicality include:  Vast filtration area – each MC-3500 chamber has 43.2 square feet of filtration area through the bottom filter fabric  Large sediment storage volume  Entire bottom area accessible for cleaning without obstructions within the row  A state-of-the-art structural design that meets AASHTO safety factors for both live loads and permanent dead loads 1.b. Applicable Sites: The Isolator Row can be effectively used for essentially all developed sites. The most common applications are highly impervious sites such as paved parking areas, roads as well as developed sites that include grassy or other landscaped areas. It is not intended to be used for construction sediments. 1.c Isolator Row Approvals: The Isolator Row has been approved on a project by project basis for thousands of projects around the United States. Following are some examples:  In Massachusetts, approvals for the State DEP requirement of 80% TSS removal on an annual load basis are issued at the Conservation Commission level, and the Isolator Row is commonly used to meet this criteria.  In 2004 the Maine DEP approved the Isolator Row based on laboratory testing of 110 micron (US Silica OK-110) particle size  Under the New Environmental Technology Evaluation program, the Ontario (Canada) Ministry of the Environment has evaluated the Isolator row and issued a Certificate of Technology Assessment Page 106 of 180 www.stormtech.com│70 Inwood Road│Suite 3│Rocky Hill│Connecticut│06067│888.892.2694│fax 866.328.8401 1.d. Manufacturer History: After many years developing and providing chamber systems for both septic and stormwater applications, StormTech owners formed StormTech, LLC in 2003 as a joint venture Company to focus exclusively on stormwater. All StormTech chambers are produced in the United States. As of this date, StormTech has millions of chambers installed, primarily for commercial applications within the United States, but installation locations also include Canada, Europe, Australia and the Middle East. The Isolator Row was developed in 2003 initially as a maintenance feature, essentially to capture sediments that could otherwise accumulate in the open graded stone that surrounds the chambers. This open graded stone serves two roles; 1) to provide the important structural soil support of the soil–structure interaction system and 2) to provide open porosity to store stormwater. The Isolator Row was found to be so effective at capturing sediments that many regulators began allowing the Isolator Row as a sediment removal BMP for water quality. StormTech engineering personnel include decades of experience in water quality. Our collective in- house engineering experience includes years with manufacturers of hydrodynamic separators, filter systems, consulting engineering and regulators. For performance evaluations relative to water quality, StormTech has gone to qualified outside researchers such as Vincent Neary, PhD, PE from Tennessee Tech University and Robert Roseen, PhD from the University of New Hampshire. History of Isolator Row Testing:  February 23, 2005 - Tennessee Tech University summarized laboratory testing on the Isolator Row in accordance with Maine DEP testing protocol. Tests demonstrated the following: o 95% TSS overall removal at 8.1 gpm/sqft for US Silica OK-110 (110 micron). o 80% captured on fabric, 15% captured in stone  October 20, 2006 - Tennessee Tech University summarized laboratory testing on the Isolator Row in accordance with New Jersey Center for Advanced Technologies (NJCAT) testing protocol. Tests demonstrated the following: o 60% TSS Removal at 3.2 gpm/sqft for Sil-Co-Sil 106 with accumulated fines (D50 = 10 microns) o 66% TSS Removal at 3.2 gpm/sqft for Sil-Co-Sil 106 (D50 = 22 microns) o 71% TSS Removal at 3.2 gpm/sqft for Sil-Co-Sil 250 (D50 = 45 microns) o 88% TSS Removal at 1.7 gpm/sqft for Sil-Co-Sil 250 (D50 = 45 microns)  August, 2007 – NJCAT summarized its third party evaluation of the Tennessee Tech test results and produced the “NJCAT Technology Verification Report StormTech Isolator Row”. Their verification is summarized as follows: o Claim 1: A StormTech® SC-740 Isolator™ Row, sized at a treatment rate of no more than 2.5 gpm/ft2 of bottom area, using two layers of woven geotextile fabric under the base of the system and one layer of non-woven fabric wrapped over the top of the system and a mean event influent concentration of 270 mg/L (range of 139 – 361 mg/L) has been shown to have a TSS removal efficiency (measured as SSC) of at least 60% for SIL-CO-SIL 106, a manufactured silica product with an average particle size of 22 microns, in laboratory studies using simulated stormwater. o Claim 2: A StormTech® SC-740 Isolator™ Row, sized at a treatment rate of no more than 2.5 gpm/ft2 of bottom area, using two layers of woven geotextile fabric Page 3 Page 107 of 180 www.stormtech.com│70 Inwood Road│Suite 3│Rocky Hill│Connecticut│06067│888.892.2694│fax 866.328.8401 under the base of the system and one layer of non-woven fabric wrapped over the top of the system and a mean event influent concentration of 318 mg/L (range of 129 – 441 mg/L) has been shown to have a TSS removal efficiency (measured as SSC) of 84% for SIL-CO-SIL 250, a manufactured silica product with an average particle size of 45 microns, in laboratory studies using simulated stormwater. o Claim 3: A StormTech® SC-740 Isolator™ Row, sized at a treatment rate of no more than 6.5 gpm/ft2 of bottom area, using a single layer of woven geotextile fabric under the base of the system and one layer of non-woven fabric wrapped over the top of the system and a mean event influent concentration of 371 mg/L (range of 116 – 614 mg/L) has been shown to have a TSS removal efficiency (measured as SSC) of greater than 95% for OK-110, a manufactured silica product with an average particle size of 110 microns, in laboratory studies using simulated stormwater.  September 2010 – The University of New Hampshire Stormwater Center released the Final Report on Field Verification Testing of the StormTech Isolator Row Treatment Unit. Testing consisted of determining the water quality performance for multiple stormwater pollutants in accordance with TARP Tier II protocol. Data was recorded for 23 storm events. o TSS median removal efficiency – 83% o Petroleum Hydrocarbons median removal efficiency – 91% o Zinc median removal efficiency – 57% o Phosphorus median removal efficiency – 33% 1.e. Requested Use Level Designation Approval: StormTech requests approval at the __________. In support of this request, StormTech is providing test results from both laboratory and field studies by others that demonstrate that the “performance requirement” is met. Product Performance Claim and Certification 80% TSS removal is achieved by sizing Isolator Rows to treat the water quality flow rate at a specific flow rate not to exceed 2.5 gpm/sqft of bottom area using two layers of Propex 315 ST, Mirafi 600X or approved equal woven geotextile.

Waiver #1 104.01.1 – All swales shall be installed with a subsurface drain. We respectfully request a waiver from this technical standard as this existing site elevations do not permit inlets to be installed at the low points in the existing and proposed swales. A literal enforcement of the provisions of this section of the ordinance will result in unnecessary hardship to this development. All swales drain to end sections or directly into the existing dry detention areas due to limited cover. To meet the requirements of this section of the ordinance to the greatest extent possible for this site, all proposed and existing swales have been graded to have a minimum slope of 1% as noted on both the Grading Plans and the typical swale cross section added to SU3.03. Waiver #2 104.02 – Minimum Flood Protection Grade of all structures fronting a pond or open ditch shall be no less than 2 feet above any adjacent 100-year local or regional flood elevations, whichever is greater, for all windows, doors, pipe entrances, window wells, and any other structure member where floodwaters can enter a building. The proposed 100-yr elevation of the east basin is 776.52. The minimum flood protection grade is 2 feet above the local 100-yr elevation at 778.52. The adjacent overtopping flood elevation is 778.50, which means the minimum flood protection grade is not the minimum of 1’ above the overtopping elevation and is only 0.02’. A literal enforcement of the provisions of this section of the ordinance will result in unnecessary hardship to this development as the existing finish floor of the building cannot be revised. To meet the requirements of this section of the ordinance to the greatest extent possible for this site, an additional 1.6 ac-ft of storage has been added to the east basin. Waiver #3 303.07 – The Lowest Adjacent Grade for all residential, commercial, or industrial buildings shall be set a minimum of 2 feet above the highest noted overflow path/ponding elevation across the property frontage. The finish floor elevation of the ESC building is 779.75. The overflow elevation along the frontage to the north (Main Street) is 781.10. The overtopping flood elevation to the south is 780.50 and the overtopping flood elevation to the northeast is 778.50. Due to existing elevations of the athletic fields, Main Street, adjacent properties, and the existing building, a waiver is requested from this technical standard. A literal enforcement of the provisions of this section of the ordinance would result in unnecessary hardship to this development as the existing finish floor of the building cannot be revised. Page 167 of 180 To meet the requirements of this section of the ordinance to the greatest extent possible for this site, an additional 1.6 ac-ft of storage has been added to the east basin. Waiver #4 501.01 – There should be no less than 2.5 feet of cover along any part of the pipe from final pavement elevation or final ground surface elevation to the top of the pipe. Due to existing elevations, we are unable to meet this requirement in all locations. A literal enforcement of the provisions of this section of the ordinance will result in unnecessary hardship to this development. To meet the requirements of this section of the ordinance to the greatest extent possible for this site, there is only one section of pipe that is under vehicular pavement that has less than 2.5' of cover. The cover is nearly 2' at the shallowest location near ST-111. All other locations where the 2.5' of cover cannot be met are in grass or sidewalk locations. A waiver from this technical standard is requested due to existing conditions.
