Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to Report Spam. Good morning, I wanted to follow up on this. With regard to your two items, please see below. 1. I will get a check in the mail. Hopefully that will go out today. 2. The ownership has changed from when that application was done. I had put Chris Plaford with Capital Asset Topsail Development LLC because they were under contract to buy it. They have since closed on the property. Attached is the new deed. With regard to the minimization, I also have included a site plan that is from the septic permit that shows the location of the wastewater system and required repair area for the home. Additionally, they had a soils report done to look at requirements and recommendations for the retaining wall due to lateral earth pressures. This was to stabilize the fill so that construction equipment can get to all sides of the home adequately. I hope this helps clarify the reasons why the home has to go back and shows that we are trying to maintain the minimization in order to adequately build the structure. There may be an option to bring the retaining wall closer to the proposed driveway turnaround in order to reduce slightly, however; it will not be a major difference. This also is noted to be under the 0.1 acre threshold for mitigation. Let me know your thoughts and your feedback. Thanks as always for your help.

Hey...I was speaking to Holley earlier about this lot and I went back to look at the NW 29, it looks like i should have looked closer at that. It doesn't appear that the 29 is appropriate since this is adjacent to tidal waters? Should this be a NW 18 instead? There was also some question about potential mitigation, so i wanted to find out about that since we are under the 0.1 acre threshold. 2 Thanks for any help.

Further, our principal foundation recommendations are summarized. Information gleaned from the executive summary should not be utilized in lieu of reading the entire geotechnical report. • The geotechnical exploration performed for the site included three (3) electronic cone penetration test (CPT) soundings drilled to termination depths of approximately 15 to 35 feet. • The proposed structure can be supported on a deep foundation consisting of 8-inch square timber piles installed to an embedment depth of 22 feet for an axial capacity of 10 kips. Alternative embedment depths and their respective capacities are given on page 5. • Groundwater was encountered in the soundings at a depth 4 inches beneath existing grades in the wetlands area, and 2.5 feet beneath existing grades outside of the wetlands. Lot 64 — Soundview Drive ECS Project No. 22:29975 1.0 INTRODUCTION February 8, 2021 Page 2 The purpose of this study was to provide geotechnical information for the foundation and bulkhead design for the residential structure proposed for lot 64 on Soundview Drive in Hampstead, Pender County, North Carolina. The recommendations developed for this report are based on project information supplied by Mr. Chris Plaford. Our services were provided in accordance with our Proposal No. 22:24808, dated January 28, 2021, as authorized by Mr. Chris Plaford on January 28, 2021, which includes our Terms and Conditions of Service. This report contains the procedures and results of our subsurface exploration programs, review of existing site conditions, engineering analyses, and recommendations for the design and construction of the project. The report includes the following items. • A review of surface topographical features and site conditions; • A review of subsurface soil stratigraphy with pertinent available physical properties; • Pile capacities and embedment depths; • Lateral earth pressure parameters; • Site development recommendations; • Suitability of soils for use as fill material; • Discussion of groundwater impact; • Compaction recommendations; • Site vicinity map; • Exploration location plan; and • CPT sounding log. Lot 64 — Soundview Drive February 8, 2021 ECS Project No. 22:29975 Page 3 2.0 PROJECT INFORMATION 2.1 PROJECT LOCATION/CURRENT SITE USE/PAST SITE USE The site is located adjacent to 117 Soundview Drive N in Hampstead, Pender County, North Carolina. It is bounded on the north by Soundview Drive, the south by the intercoastal waterways, and the east and west by neighboring residential lots. Figure 2.1.1 below shows an image of where the site is located. Figure 2.1.1 Site Location The site was clear prior to the conducted subsurface exploration. Based on our site visit and approximate elevations from Google Earth, the site is relatively flat with typical elevations on site ranging from approximately 5 to 9 feet. According to FRIS, the site is in the AE 12 flood zone. 2.2 STRUCTUAL INFORMATION/LOADS At the time of this report, additional project information including structural loads and grading information was not available. The following information explains the assumed finished floor elevations and anticipated structural loads for the purpose of the recommendations made in this report: Table 2.3.1 Structural Design Values SUBJECT DESIGN INFORMATION / EXPECTATIONS Usage Residential Column Loads Up to 25 kips Wall Loads Up to 2 klf Elevations +/- 2 feet of existing grades Lot 64 — Soundview Drive February 8, 2021 ECS Project No. 22:29975 Page 4 3.0 FIELD EXPLORATION TESTING Our exploration procedures are explained in greater detail in Appendix B including the insert titled Reference Notes for Cone Penetration Soundings. Our scope of work included performing three (3) CPT Soundings. The approximate sounding locations are shown on the Location Diagram in Appendix A. 3.1 SUBSURFACE CHARACTERIZATION The subsurface conditions encountered were generally consistent with published geological mapping. The following sections provide generalized characterizations of the soil. Please refer to the CPT sounding log in Appendix B. The site is located in the Coastal Plain Physiographic Province of North Carolina. The Coastal Plain is composed of seven terraces, each representing a former level of the Atlantic Ocean. Soils in this area generally consist of sedimentary materials transported from other areas by the ocean or rivers. These deposits vary in thickness from a thin veneer along the western edge of the region to more than 10,000 feet near the coast. The sedimentary deposits of the Coastal Plain rest upon consolidated rocks similar to those underlying the Piedmont and Mountain Physiographic Provinces. In general, shallow unconfined groundwater movement within the overlying soils is largely controlled by topographic gradients. Recharge occurs primarily by infiltration along higher elevations and typically discharges into streams or other surface water bodies. The elevation of the shallow water table is transient and can vary greatly with seasonal fluctuations in precipitation. Table 3.1 Subsurface Stratieraohv Approximate Stratum Description Ranges of Depth Range N*-Values(1) blows per foot (bpf) 0.0 to 20.0 1 Very Loose to Medium Dense, Silty and Clean SAND 2 to 12 (SM, SP); Moist to Saturated. 20.0 to 35.0 II Loose to Medium Dense, Silty and Clean SAND (SM, 5 to 22 SP); Saturated Notes: (1) Equivalent Corrected Standard Penetration Test Resistances 3.2 GROUNDWATER OBSERVATIONS Water levels were measured in our CPT soundings in Appendix B. Groundwater was encountered in the soundings at a depth 4 inches beneath existing grades in the wetlands area, and 2.5 feet beneath existing grades outside of the wetlands. Due to this property's location within the vicinity of the intercoastal waterways, the groundwater level is heavily influenced by tidal forces. Variations in the long-term water table may occur as a result of changes in precipitation, evaporation, surface water runoff, construction activities, and other factors. Lot 64 — Soundview Drive February 8, 2021 ECS Project No. 22:29975 Page 5 4.0 DESIGN RECOMMENDATIONS 4.1 FOUNDATIONS The proposed structures can be supported on a deep foundation system consisting of 8-inch timber piles. The following table shows the allowable pile capacities for 8-inch square timber piles. The embedment depth listed is in reference to the existing grade at the time the sounding was performed. Table 4.1.1: 8-Inch Square Timber Piles Embedment Depth (Feet) Axial Capacity (kips) Uplift (kips) 21 8 2.0 22 10 2.5 25 20 3.5 27 23 3.7 In our opinion, piles installed to depths shallower than recommended depths, would not provide long- term stability of the proposed structure. Pile capacity analyses were performed assuming a free head condition and the provided compression and tension capacities are based on a factor of safety of 2.0 and 3.0, respectively. We recommend that the pile driving hammer used to install each pile have a minimum rated energy blow of 1,800 foot-pounds. Driving criteria and bearing elevations should be established prior to driving piles. Based on the subsurface conditions, we recommend that the piles installed be limited to a pre -auger depth of approximately 9 feet below existing grades. It is suggested that several over length piles be driven prior to the start of production pile driving, to establish the driving criteria, pile lengths to be ordered and to determine if auger "pilot" holes are justified. Production piles should not be ordered until the pile lengths can be determined. A minimum of two over length piles are recommended for the structure. The over length piles could be driven in production pile locations. Pile installation operations and load tests, if necessary, should be monitored by a senior soil technician working under the supervision of a Licensed Engineer. ECS would be pleased to develop driving criteria for the project once the method of installation and the contractor has been selected. Lot 64 - Soundview Drive ECS Project No. 22:29975 4.2 LATERAL EARTH PRESSURES February 8, 2021 Page 6 The bulkhead wall utilized for this project should be designed to withstand the lateral earth pressures and hydrostatic forces exerted upon it. In the design of bulkhead walls to restrain compacted engineered fill or in -situ natural soils, the in -situ soil parameters that can be utilized for the site is summarized in the table 4.2.1 and 4.2.2. The depths are in reference to the depth below the existing grade at the time the sounding and borings were performed.

The increased lateral pressures generated by surcharge loads (i.e. slopes, parking, construction and building areas, etc.) should be considered in the design. A typical traffic surcharge load is 250 psf. Based on our subsurface findings, groundwater was noted at approximately 0.33 feet (4 inches) beneath the ground surface in the vicinity of the proposed retaining wall. The wall should be designed to resist hydrostatic pressures. Lot 64 — Soundview Drive ECS Project No. 22:29975 February 8, 2021 Page 7 For wall conditions where wall movement cannot be tolerated or where the wall is restrained at the top, the "At Rest" earth pressure should be used. For wall conditions where outward wall movement in the range of 0.5 to 1 percent of the wall height can be tolerated, the "Active" earth pressure should be used. In evaluating the resistance of soil to lateral loads imposed by structures, the "Passive" earth pressure should be used. Please note that the full development of passive pressure requires deflections toward the soil mass on the order of 1 to 4 percent of the wall height. Lot 64 — Soundview Drive February 8, 2021 ECS Project No. 22:29975 Page 8 5.0 SITE CONSTRUCTION RECOMMENDATIONS 5.1 SUBGRADE PREPARATION 5.1.1 Stripping and Grubbing The subgrade preparation should consist of stripping vegetation, rootmat, topsoil, and any soft or unsuitable materials from the 10-foot expanded building footprint. The CPT soundings encountered 6 to 8 inches of topsoil on site. 5.2 EARTHWORK OPERATIONS —STRUCTURAL FILL Prior to placement of Structural Fill, bulk samples (about 50 pounds) of on -site and/or off -site borrow should be submitted to ECS for laboratory testing, which will typically include Atterberg limits, natural moisture content, grain -size distribution, and moisture -density relationships (i.e., Proctors) for compaction. Import materials should be tested prior to being hauled to the site to determine if they meet project specifications. Alternatively, Proctor data from other accredited laboratories can be submitted if the test results are within the last 90 days. Satisfactory Structural Fill Materials: Materials satisfactory for use as structural fill should consist of inorganic soils with the following engineering properties and compaction requirements. STRUCTURAL FILL INDEX PROPERTIES Subject Property Building and Pavement Areas LL < 40, PI<20 Max. Particle Size 4 inches Fines Content Max. 25 % > #200 sieve Max. organic content 5% by dry weight STRUCTURAL FILL COMPACTION REQUIREMENTS Subject Requirement Compaction Standard Standard Proctor, ASTM D698 Required Compaction 95% of Max. Dry Density Moisture Content -2 to +2 % points of the soil's optimum value Loose Thickness 8 inches prior to compaction On -Site Borrow Suitability: Significant natural deposits of soils are present on the site. These occur mostly at relatively shallow depth below the surface. Fill Placement: Fill materials should not be placed on frozen soils, on frost -heaved soils, and/or on excessively wet soils. Borrow fill materials should not contain frozen materials at the time of placement, and frozen or frost -heaved soils should be removed prior to placement of structural fill or other fill soils and aggregates. Excessively wet soils or aggregates should be scarified, aerated, and moisture conditioned.

These values are recorded continuously as the cone is pushed to the desired depth. CPT data is corrected for depth and used to estimate soil classifications and intrinsic soil parameters such as angle of internal friction, preconsolidation pressure, and undrained shear strength. The graphs below represent one of the accepted methods of CPT soil behavior classification (Robertson, 1990). 1. Sensitive, Fine Grained 6. Clean Sands to Silty Sands 2. Organic Soils-Peats 7. Gravelly Sand to Sand 3. Clays; Clay to Silty Clay 8. Very Stiff Sand to Clayey Sand 4. Clayey Silt to Silty Clay 9. Very Stiff Fine Grained 5.

These values are recorded connuously as the cone is pushed to the desired depth. CPT data is corrected for depth and used to esmate soil classificaons and intrinsic soil parameters such as angle of internal fricon, pre-consolidaon pressure, and undrained shear strength.
