The items covered by this bond that require some correction are as follows: 1. Storm Drainage. In your January 30, 2018 letter you thoroughly reviewed on the TV inspection report by Accumark and the reports by Froehling and Robertson (F&R) regarding repairs that had been made to the sewer lines by Dillard. You noted the discrepancies between what had been accomplished and what still need to be done. You determined where some lines required cleaning and an additional TV inspection after cleaning to determine any remedial work. We have had the cleaning and TV inspection done and include the results of this work. We have also identified the additional storm water repairs that need to be done based on the TV inspection. Attached is a summary of the proposed actions. In your letter you identify certain lines as having excessive deflection requiring replacement. In its report, Accumark identified these places as "sags" not deflections. The nature of the HDPE pipe is such that a certain amount of curvature is permissible as is a certain amount of deflection. Curvature is what produces a sag, deflection is when the pipe assumes an egg cross section. A certain amount of "egging" is required of the pipe because that is how a flexible pipe supports the vertical load, That is also why proper compaction on the sides of the pipe is so important. I have examined the video of the four sections of pipe that you requested be replaced due to deflection and I do not see deflection that would warrant replacement of the pipe. (Excerpts from the report attached.) 2. Paving repair: F&R evaluated the paving within the Townhouse community. (Copy attached). We will make the repairs identified in their report. 3. Miscellaneous items. Included in this bond are street name signs, traffic control signs and guardrail. We need to inventory what has already been provided and determine what, if anything is missing. Perhaps you can have a staff member review the plans and walk the community with me to identify what has not been provided. We will provide these items. When we reach an agreement on what needs to be completed I will seek authorization from Tribal to proceed.

Trice c/o William L. Jeffries, Jr. Kane, Jeffries, Cooper & Carollo, LLP 1700 Bayberry Court, Suite 103 Richmond, Virginia 23226 RE: HTC Abington Place (Public and Private Roads) and HTC Abington Plase Phase 2 (Public and Private Roads) — Storm line Video and inspection Reports Review Dear Mr. Jefferies: i have reviewed the Accumark pipe video report and F&R inspection documentation provided for the referenced project. Comments are as follows: General Comments: l . Accumark Report — All defects identified in this report as "poor condition" or "immediate attention" were not addressed. These are defects identified to fail within 10 years or sooner. Repair the defects that were not repaired or provide an Engineer certification why repair is not necessary. 2. All pipes are private unless otherwise noted "within VDOT R/W". 3. Concrete Pipe/Culverts Cracks: Longitudinal cracks with a width less than one hundredth of an inch (0.01) are considered hairline and minor. They shall be noted in the inspection report; however, no remedial action is necessary. Longitudinal cracks having a width equal to or greater than one hundredth of an inch (0.01 but equal to or less than one tenth of an inch (0.1) and determined by the Engineer to be detrimental to the structure shall be sealed by a method proposed by the pipe\culvert manufacturer and approved by the Engineer. Pipes or culverts having longitudinal cracks with widths greater than one tenth of an inch (0,1) and determined to be beyond the limits of a satisfactory structural repair shall be replaced by the Contractor at his expense to the satisfaction of the Engineer. Pipes or culverts having displacement across the crack greater than 0.1 inch but less than 0.3 inch shall be remediated. Remediation methods shall be in accordance with recommendations of the pipe or culvert manufacturer, be acceptable to and authorized by the Engineer before implementation and shall be the sole responsibility of the Contractor. Pipes\culverts having displacement across the crack greater than 0.3 inch shall be replaced by the Contractor at his expense to the satisfaction of the Engineer. Transverse cracks will be evaluated using the same criteria as indicated above for longitudinal cracks. 4. Thermoplastic Pipe/Culvert — what is the pipe DR?� `\\ Deflection of 5 percent up to 7.4 percent will be evaluated by the Engineer. If the 10�\ pipe\culvert experiences additional defects along with deflection of 5 percent up to 7.4 percent of the original pipe\culvert's diameter, the pipe\culvert shall be remediated. Remediation methods shall be in accordance with recommendations of the pipe\culvert manufacturer, be acceptable to and authorized by the Engineer before proceeding, and shall be the sole responsibility of the Contractor. If the pipe\culvert is deflected 7.5 percent or greater of the original diameter, the pipe\culvert shall be replaced by the Contractor at his expense to the satisfaction of the Engineer.

F&R's understanding of the project was developed from our discussions and site meeting with you, and our review of the provided site layout drawings by Dominion Development Resources dated 3/21/07. Project Information F&R was requested to perform this limited subsurface exploration to provide information on the existing conditions of the asphalt pavements, subgrades, and concrete curbing for the private drive lanes at the above mentioned project site. We understand the County of Albemarle will utilize the information provided herein to help formulate a decision on whether or not the existing road conditions are to be accepted into its system. Exploration Procedures F&R collected thirteen (13) asphalt cores, designated C-1 through C-13, at the approximately locations indicated on the Field Test Location Plan. F&R recorded the asphalt thickness and depth of the underlying subbase gravel at each cored location. Hand auger borings were performed at each location and the soil cuttings extracted were visually classified by a geotechnical engineer during field operations. Dynamic Cone Penetrometer (DCP) testing was performed on the subgrade soils below the subbase stone layers at each location at roughly 1 foot intervals. The DCP is a device utilizing a 15 pound steel weight falling 20 inches to drive a cone with a diameter of 1.5 inches and height of 1.66 inches a distance of 1.75 inches into the ground. The number of hammer blows required to drive the cone three successive 1.75 inch increments is recorded, and these blow counts provide a general indication of in -situ soil conditions and has been correlated with certain engineering properties of soils. Corporate HQ: 3015 Dumbarton Road Richmond, Virginia 23228 T 804.264.2701 F 804,264.1202 www.fandr.com VIRGINIA • NORTH CAROLINA • SOUTH CAROLINA • MARYLAND • DISTRICT OF COLUMBIA A Minority -Owned Business Some limited testing of the concrete curb and gutter, using the Swiss rebound hammer at approximately 500 foot intervals was performed. Individual test locations are indicated on the attached Field Test Location Plan. The Swiss Hammer provides a rebound number, which is an indication of the concrete surface hardness, and can be roughly correlated with concrete strength. However, it should be understood that this method is not considered as reliable as Windsor Probe testing, or testing concrete core samples. This method was chosen because it is nondestructive and can be performed very rapidly. In addition, F&R walked the private drive lanes and noted locations where significant alligator and/or tension cracks were evident. These locations are also indicated on the attached location plan. Exploration Results Hand auger borings encountered existing fill materials below the subbase gravels at each test location and shallow hand auger refusal on these materials was typical. Refusal was experienced at the top of the subgrade fill materials (i.e. just below the subbase gravel layer) at 9 of the 13 test locations. Hand auger refusal was believed to have been experienced on coarse gravel within fill materials. Recovered fill materials were generally described as brown, very moist, silty SAND (SM) and sandy SILT (ML), with little gravel and mica. Although the presence of coarse gravel within the fill materials is believed to have inflated the recorded DCP blow counts to come extent, we still considered the encountered subgrade materials to be relatively dense and firm. The field Pavement Subgrade — DCP Reports for each test location is attached and a summary of each location is detailed in the table below. Test Na.

The subsurface materials encountered at the test locations were considered to be firm and stable, and suitable for flexible pavement support. However, field measurements indicate that the asphalt layer at test locations C-3 and C-11, and the subbase layer at C-7 and C-8, do not meet the specified design thicknesses. We note that cracking was not observed around C-7 and C-8, but significant cracking was noted around C-3 and C-11. Based on our visual evaluations and the subgrade materials encountered, we feel the areas of cracking indicated on the attached site plan is likely the result of insufficient asphalt thickness. It is F&R's opinion that the cracked areas highlighted should be repaired, with the repair consisting of removal of the cracked asphalt and gravel base as necessary to allow for replacement with the required thickness of new asphalt. As a minimum, we recommend he cracked areas be removed and replaced, and any other areas of insufficient asphalt thickness which become evident during this process should also be removed and replaced. In addition, the exposed subgrades should be probed by the geotechnical engineer to verify that they are suitable for pavement support. It is F&R's judgment that no remedial action is necessary at the two locations where the gravel base did not meet thickness requirements (i.e. C-7 and C-8). At each of these locations a thicker asphalt layout was present to compensate for the lesser gravel thickness. The Swiss Hammer test results provided a few locations that correlated to a compressive strength of less than the specified 3,000psi minimum. We recommend that these values be reviewed by the civil engineer and Albemarle County to determine whether the concrete will meet its intended function.
