This project was previously permitted as a low density project on October 2, 2007 (SW8 070653) and a modification was approved on March 2, 2016 for Phase II that used a wet pond to treat the runoff from a piped system. The original project was designed as a low density subdivision with roadside swales. The roads for Phase III will have curb and gutter and storm water will be conveyed to a wet detention basin by culverts. The project will remain a "Low Density" project and the allowable BUA per lot will remain at 4,006 sf. The site drains to Stones Creek (SA; HQW) and Turkey Creek (SA; ORW). The project for this submittal will have three (4) drainage basins. The first two are the two areas that drain to Stones Creek (Drainage Area No. 1) and Turkey Creek (Drainage Area No. 2). Drainage Basin No. 3 is the area that drains to the wet pond for Phase II. The impervious area shown for this drainage area is also included in the impervious area for Drainage Area No. 2. Drainage Area No. 2 includes the area shown for Drainage Area No. 3 & 4. The impervious area proposed for the next phase of construction is shown in both Drainage Areas No. 2 & 4. Future impervious area is provided in the permit for Drainage Area No. 4 to allow for a road extension in the future. The pond for this phase of the project is located outside the % mile line of Turkey Creek and is located in Drainage Area No. 4. The subdivision is 319 acres and the allowable impervious area remains at 24.4% which equates to 3,390,536 sf of impervious area. Paved Areas = 210,288 sf Lot BUA = 523,785 sf Future Impervious Area = 2,656,463 sf 3,390,536 sf — 77.84 ac 77.84/319 = 24.4% The site meets the low density criteria for subdivisions.

There appears to be a quantity of two Lot#157's. Please explain or revise as necessary. Response: This was an oversite. The lot numbers have been corrected as well as the pages in the permit applications and storm water calculations. Copies of the revised pages are enclosed. 2. I didn't see a signed deed restriction document in the package. Please explain or provide this for the additional phase of this project. Response: We are still going off the original approved deed restrictions which allowed 4,006 sf per lot. 3. You may need to add a drainage easement around the stormwater pond. Please advise. Response: The pond is located in"Common Area" for the HOA. A note has been placed on Sheet C-5 stating this that the pond is in a drainage easement and will be maintained by the HOA. 4. The cover sheet of the plans states"Hooser"instead of"Hoosier". Probably should revise that. Response: The name has been corrected. Provided are two copies of the revised plans(Cover,C-1,C-2.1,C-2.2,C-2.3,C-2.4,C-2.5,C-2.6, C- 2.7,C-3.1,C-3.2,C-3.3,C-5.0, C-5.1,C-5.2&C-5.3) along with two copies of the revised application pages and storm water calculations.

This project was previously permitted as a low density project on October 2, 2007 (SW8 070653) and a modification was approved on March 2, 2016 for Phase II that used a wet pond to treat the runoff from a piped system. The original project was designed as a low density subdivision with roadside swales. The roads for Phase Ill will have curb and gutter and storm water will be conveyed to a wet detention basin by culverts. The project will remain a "Low Density" project and the allowable BUA per lot will remain at 4,006 sf. The site drains to Stones reek (SA; HQW) and Turkey Creek (SA; ORW). The project for this submittal will have ((4) drainage basins. The first two are the two areas that drain to Stones Creek (Drainage Area No. 1) and Turkey Creek (Drainage Area No. 2). Drainage Basin No. 3 is the area that drains to the wet pond for Phase II. The impervious area shown for this drainage area is also included in the impervious area for Drainage Area No. 2. Drainage Area No. 2 includes the area shown for Drainage Area No. 3 &4. The impervious area proposed for the next phase of construction is shown in both Drainage Areas No. 2 & 4. Future impervious area is provided in the permit for Drainage Area No. 4 to allow for a road extension in the future. The pond for this phase of the project is located outside the mile line of Turkey Creek and is located in Drainage Area No. 4. The subdivision is 319 acres and the allowable impervious area remains at 24.4% which equates to 3,390,536 sf of impervious area. Paved Areas = 210,288 sf °I Lot BUA = 519,779 sf �-7/'/rt.

This letter, with attachments, is the report of our estimation. Field Testing On November 17, 2016, ECS conducted an exploration of the subsurface soil and SHWT conditions at one requested location shown on the attached Boring Location Plan (Figure 1). The purpose of this exploration was to estimate the SHWT of the in situ soils for the design of for the proposed stormwater BMP area. ECS met with Mr. Mark Hargrove P.E. with Port City Consulting Engineers, PLLC in order to locate the boring. ECS explored the subsurface soil and groundwater conditions by advancing one hand auger boring into the existing ground surface at the requested boring location. ECS visually classified the subsurface soils and obtained representative samples of each soil type encountered. ECS recorded the SHWT and groundwater elevation observed at the time of the hand auger boring. The attached SHWT sheet provides a summary of the subsurface conditions encountered at the hand auger boring location. The SHWT and groundwater elevation were estimated at the boring location below the existing grade elevation. Below is a summary of each boring location. Location SHWT Groundwater B-1 24 inches 36 inches The SHWT may vary within the proposed site due to changes in subsurface conditions and elevation.

ECS appreciates the opportunity to provide our services to you on this project. If you have any questions concerning this report or this project, please contact us at (910) 686-9114.
