The site is located on the west side of Springmill Road, approximately 1000’ north of 116th Street. The site is more specifically located in part of Section 34, Township 18 North, Range 3 East, City of Carmel, Clay Township, Hamilton County, Indiana. EXISTING SITE CONDITIONS Please refer to the Jackson’s Grant Stormwater Master Plan prepared by Williams Creek Consulting, Inc., for more details of the overall drainage for Jackson’s Grant. The Master Plan includes the modeling for the current and proposed conditions for Jackson’s Grant, Section 7. The entire Jackson’s Grant development drains to Williams Creek, which bisects the site into the East and West Basin. PROPOSED SITE CONDITIONS Please refer to the Jackson’s Grant Stormwater Master Plan prepared by Williams Creek Consulting, Inc., for more details of the overall drainage for Jackson’s Grant. The Master Plan includes the modeling for the current and proposed conditions for Jackson’s Grant, Section 7. A Technical Memorandum from V3 outlines changes to the Master Plan that were made with Section 6 which effect Section 7. The memorandum and associated information can be found in Appendix A. Jackson’s Grant, Section 7, lies to the north of previously completed Jackson’s Grant, Section 6. Between Section 6 and 7, there are a total of 9 BMP’s: 13A, 13B, 13C, 13D, 14B, 14C, 15A, 15B and 15C. 13B, 13D and 14C will be the last BMP’s before outleting to Williams Creek. Information and calculations are included in this report to show conformance to the Williams Creek Jackson’s Grant Master Plan Report. STORM SEWER DESIGN The use of Manning’s equation was used for determination of storm drain pipe sizes for non-submerged conditions. The storm drain system is capable of passing the 10-year storm event with free water surface elevations below the crown of pipe. Minimum storm drain flowing velocity for full pipe flow shall be 2.5 fps and maximum storm drain flowing velocity for full pipe flow is 10 fps. The inlet grate castings are designed such that the 10-year storm event shall be sufficiently conveyed into the storm sewer system at 50% efficiency. 12/18/19 5 of 41 The inlets are spaced to allow one lane of traffic to remain open during the 10-year storm event. The Autodesk Storm and Sanitary Analysis program was utilized to calculate the pipe sizes for this project. Appendix B features the reports from this model. WATER QUALITY All water quality design information can be found in the Water Quality Report performed and completed by Williams Creek Consulting.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

The changes to the Master Plan described herein only pertain to BMPs located within Section 6 of the overall development and include 13A, 13B, 13D, 14B, 14C, 15A, 15B and 15C. No other hydraulic or hydrologic calculations were changed as part of this Master Plan update. An update to the Master Plan was required as part of the Section 6 development. In the approved version from 2014, the area encompassing Section 6 and the above listed BMPs was conceptually planned. During detailed grading and development of the construction documents by Stoeppelwerth & Associates, areas of direct rear lot discharge were identified to be greater than originally master-planned. As such, V3 has updated the hydraulic model to account for these changes. Specifically, Basins 13A, 13C and 15C required updates to allow for greater direct discharges. Appendices A-5 and A-6 of the approved Master Plan have been updated accordingly and can be found at the end of this memorandum. Below, please find comparison tables indicating that the overall stormwater management performance criteria prescribed by the 2014 approved Master Plan have been met after this update. Table 1 summarizes previously approved release rates. Table 2 summarizes previously approved BMP performance. Table 3 summarizes updated BMP performance.
