This system (check one): ❑ does ® does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ❑ does not incorporate pretreatment other than a forebay. Important maintenance procedures: — Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). — No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. — Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. -- If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. — Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).

(Terracon) is pleased to present this report of Additional Geotechnical Engineering Services for the proposed Bertie High School in Windsor, North Carolina. Our services were provided in accordance with Terracon's Supplement to Agreement for Services dated March 5, 2012. Project Information The project information is based on our initial work at the site and our review of drawings received from Mr. Steve Janowski in an electronic mail correspondence dated March 2, 2012. We understand a stormwater management structure is planned for the Bertie High School. We were provided drawings that indicated the proposed location of the pond and the proposed location of three test borings. We were requested to drill to a depth of 15 feet at each boring location in order to provide soil information in the footprint of the proposed pond. We were also requested to perform hand auger borings in these three locations to determine the seasonal high water table. In addition, we obtained an undisturbed sample of the upper clay and performed laboratory permeability testing on this clay sample. Field Exploration The boring locations were staked by a representative of Terracon using a measuring wheel and the existing site features as reference points. Elevation information was interpolated from a drawing provided by Hite Associates. The locations and elevations of the borings should be considered accurate only to the degree implied by the means and methods used to define them.

The findings of our hand auger borings is summarized below: P-1 0-4 inches — Topsoil and rootmat 4-12 inches — Clayey sand — 10YR-6-6 Brownish Yellow 12-24 inches — Silty Clay — 10YR-6-2, Light Brownish Gray with 10YR-5-8 Yellowish Brown Mottles 24-36 inches — Silty Clay — 1 OYR-6-1 Gray with 1 OYR-5-8 Yellowish Brown mottles P-2 0-4 inches — Topsoil and rootmat 4-14 inches — Clayey sand — 10YR-6-4 Light Yellowish Brown 14-22 inches - Silty Clay — 10YR-6-2, Light Brownish Gray with 10YR-5-8 Yellowish Brown Mottles 22-36 inches — Silty Clay — 10YR-6-1 Gray with 1 OYR-5-8 Yellowish Brown mottles P-3 0-4 inches — Topsoil and rootmat 4-12 inches — Clayey sand — 10YR-6-6 Brownish Yellow 12-24 inches — Silty Clay — 10YR-6-2, Light Brownish Gray with 10YR-5-8 Yellowish Brown Mottles 24-36 inches — Silty Clay — 1 OYR-6-1 Gray with 1 OYR-5-8 Yellowish Brown mottles Based on our hand auger borings, it is our opinion that the Seasonal High Water Table is at approximately 14 to 15 inches below the existing ground surface. Terracon subcontracted Carolina Drilling to drill the three soil test borings to a depth of approximately 15 feet below the existing grade. The approximate locations of the borings are shown on the attached site plan. The soil test borings were performed by a trailer -mounted power drilling rig utilizing mud rotary drilling procedures. Standard Penetration Tests were performed using a safety hammer operated by a cathead and rope assembly. Terracon personnel visually classified the split -spoon soil samples in general accordance with the Unified Soil Classification System. An undisturbed sample was obtained in boring P-2 from a depth of 3 to 5 feet. Laboratory permeability testing was performed on this sample in general accordance with ASTM D5084. Responsive o Resourceful a Reliable KI Report of Additional Geotechnical Engineering Services Irerracon Proposed Bertie High School oWindsor, NC March 8, 2012 o Terracon Project 72125002 The results of this testing found the permeability of the soil tested to be 8.56 x 10­6 cm/sec or less than 0.01 inches per hour. The Permeability Test Report is attached with this report. Our Boring Logs, site plans provided to us, General Notes and a description of the Unified Soil Classification System are also included with this report. Limitations The boring logs represent our interpretation of the subsurface conditions based on the field logs, and visual examination of samples by an engineer or geologist. Conditions encountered at each boring location are indicated on the individual boring logs. Stratification boundaries on the boring logs represent the approximate location of changes in soil types; in -situ, the transition between materials may be gradual. Terracon is not responsible for interpretation of the boring logs by others. Subsurface conditions away from or between the boring locations likely vary. Laboratory testing may reveal other soil types. Water levels were taken at the time of drilling. Water levels can fluctuate seasonally and with changes in precipitation, runoff or other factors. Water levels at other times may be higher or lower than observed at the time of drilling. The assessment of site environmental conditions or the presence of contaminants in the soil, rock, surface water or groundwater of the site was beyond the scope of this geotechnical study. We appreciate the opportunity to be of service to you on this project. If you have any questions concerning this report, or if we may be of further service, please contact us.

In low permeability soils, the accurate determination of groundwater levels may not be possible with only short-term observations. DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the unified Soil Classification System, Coarse Grained Soils have more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a 4200 sieve; they are principally described as clays if they are plastic, and silts if they are slightly plastic or non -plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined on the basis of their in -place relative density and fine-grained soils on the basis of their consistency.
