This is a minor subdivision action called a Lot Split — making one large lot into two smaller ones. The Planning Departments of Pulaski County (where it is located) and the City of Little Rock (which has extraterritorial jurisdiction) would like some type of acknowledgement from the state, that the proposed lot split is feasible with regard to septic fields. Because the back yards abut the Arkansas River, and the elevated -type house may be built with outside earthen slopes of 27-ft length, rising from ground level to the first floor level, we have to place the two septic fields in the undisturbed portion of the front yard. The diagram in Meints's attached letter shows a minimum 35-ft wide by 180-ft long area of the left front yard. This is the minimum, the right front yard is 48 feet wide. I know that your regulations do not require concurrence for less than a 3-lot subdivision. However, could you state your opinion that you agree with Meints's findings?

I would limit the number of bedrooms in each home to 4. The loading rate is 0.75 gal/sq ft/day. Each home would have a septic tank, pump, and 300' of field line. I can fit that in the area noted, as long as I understand where the driveways and other utilities come across the yard. The soil is simply alluvial, and mostly sand, no issues with a disposal site and nothing advanced. Thanks. David A.

It is further to certify that the attached technical data supports the fact that the proposed Hennard River Subdivision, if it is developed as proposed, will not result in any increase in flood levels during occurrence of the Base Flood (100-yr) discharge at published cross sections in the Flood Insurance Study for Pulaski County, Arkansas dated Revised November 2, 1994 and nor will it result in any increase in flood levels at unpublished cross sections in the vicinity of the proposed development. Attached are the following documents that support my findings: SUMMARY REPORT OF HENNARD RIVER SUBDIVISION "NO -RISE" MODELING HENNARD RIVER SUBDIVISION "NO -RISE" ANALYSIS TABLE HENNARD RIVER SUBDIVISION SECTION LOCATION MAP HENNARD PRE- & POST -PROJECT ANALYSIS W/OUTPUTS Date: JULY 27, 2015 Signature: David Hamilton, P.E. Project Engineer Summary Report of "No -Rise" Modeling Analysis Hennard River Subdivision, Lots 1 and 2 12400 County Farm Road The objective of this project was to perform a hydraulic modeling analysis of existing terrain and proposed construction to be located on the property known as Hennard River Subdivision owned by Dustin Hennard Homes, Inc. This analysis was necessary because the proposed construction takes place within the Floodway of the Arkansas River in Pulaski County, Arkansas. The analysis was done pursuant to CFR Title 44, Chapter 1, Section 60.3(d)(3) of the NFIP regulations. The analysis was performed to determine whether an increase in the Floodway water surface elevation would be expected to occur due to the proposed construction. This study is meant to confirm the viability of the proposed project and to demonstrate that the proposed project will not cause any rise in flood levels to the Floodway water surface elevation of the Arkansas River, during discharge of the 100-yr base flood. The hydraulic model used in the study was the US Army Corps of Engineers LRD-1 backwater model. The latest LRD-1 backwater data file was obtained from the Little Rock District (LRD) Corps of Engineers Hydrology & Hydraulics Branch. This model is the predecessor to the USACE "HEC-2" computer model and was developed in 1965 and has subsequent updates by USACE. Earthen berms proposed to align with the river's current and to be situated on the immediate right overbank area of the river were modeled. These berms represent fill or structures to be placed in the Floodway for the purpose of elevating the houses as well as the front, back, and side yards of the houses. The berms — which are 112 to 114 feet wide at the base and 60 feet wide at the top - block out a small portion of the river's overbank flow on the right side, and are elevated 4 (+/-) feet above the existing ground surface to achieve a height slightly above the Base Flood Elevation, Finished Floor elevation of proposed houses must be at least 2.0 feet above the BFE. The two levee -like (in cross -sectional shape) berms of 200-ft length were modeled appropriately, one on each of the proposed two lots in the subdivision. They are positioned near the mid -depth of each lot, leaving space in the front yard area for septic fields. The berms are offset from each other, owing to the need to locate Lot 1's berm closer to the street because of lot depth limitation. See the attached "Hennard River Subdivision Section Location Map". Each berm tapers down to existing ground at both ends over a distance of 10 feet. In order to model accurately the water surface elevations at the proposed construction, two new cross sections were developed from new overbank topography blended with river -bottom topography obtained from existing RM 175.3 (which is less than three -tenths of a mile downstream). These new sections were made for 1) the eastern two model sections representing the eastern edge of the site, where natural ground is one to two feet higher than the rest of the site, and 2) the other four model sections representing the midline and western edge of the site. A total of six new model sections were inserted into the right bank of LRD-1 between published sections RM 175.3 and RM 176.3, which are downstream and upstream, respectively, from the study area. The floodway boundaries are some 1150 feet west and 650 feet south of the site, as coded and mapped for the latest LRD-1 model. The new model sections were inserted at the upper and lower end of each berm, and include the section representing natural ground at the west and east property lines, 10 feet from the end of the elevated portion of each berm. These six added cross sections were used to create a pre -project conditions (i.e., "corrected" and "existing") model. (The version of LRD-1 used also includes updated post -project modeling of the downstream "Two Rivers Harbour Estates", engineered by Civil Design, Inc.) The "PRE" conditions model was then copied and revised to reflect post -project conditions. For "POST" conditions, the proposed berms were added to the model at their respective model sections, as elevated ground profile. After running the LRD-1 model for both PRE, and POST conditions, the output data was tabulated. It was determined that there was no rise in the floodway water surface elevation due to the proposed construction. The following table summarizes the water surface elevations and energy grade line for the 100-year Base Flood discharge of 480,000 cfs.
