III Deer Hill Drive Wilmington, North Carolina RFTS Job No. 911-13 Dear Mr. Daniel: RFTS is pleased to provide testing services during the design phase of the proposed. Deer Crossing Phase III project located off Deer Hill Drive in Wilmington, North Carolina. Specific site grading plans had not been provided to us at the time this report was prepared. DESCRIPTIMN OF ACTIV TIES AND + N31NGS As requested, our staff visited the site on November 1. 2013, to perform infiltration testing and estimate the seasonal high watertable at two locations identified by you. The purpose of this testing was to provide soil parameters for stormwater infiltration design. Seasonal High Watertable Estimate Hand auger borings were advanced at two locations to a depth of approximately 10 feet below the existing ground surface in the area proposed b} the civil designer for an infiltration structure. The encountered soils were logged and visually classified by depth and a Munsell Soil Color Chart was used to determine the hue. value, and chroma of the visually distinct soil layers. Our soil logs are presented in Table 1. INF-1 Soils encountered at this boring location consistedentirely of interbedded relatively clean fine sands (USCS Soil Group "SP" and "SP-SC") through the boring termination depth of 122 inches below the existing ground surface. No distinct zones of soil cementation were encountered in the profile. Based on our experience with similar soils and comparisons of the soil coloration to the Munsell Chart, it is our opinion that seasonal high water table level occurs approximately 1.02 inches below the existing the ground surface. No standing water was encountered at this boring location through the depth investigated.

No distinct zones of soil cementation were encountered in the profile. Based on our experience with similar soils and comparisons of the soil coloration to the Munsell Chart, it is our opinion that seasonal high water table level does not occur through the depth investigated. No standing water was encountered at this boring location through the depth investigated of 120 inches below the existing ground surface. Infiltration Testing Infiltration testing was performed using a model 2800 Guelph Permeameter which is a constant -head device which operates on the Mariotte siphon principle and is referenced in ASTM D-5126. The permeameter is used to determine field saturated hydraulic conductivity in centimeters per second for soil at a specified depth. This testing involves advancing a borehole to the desired infiltration depth and introducing water at a constant head to determine the steady state flow rate from which the hydraulic conductivity can be calculated. Our testing was performed approximately 36 inches below the existing ground surface. The results of our permeameter testing are presented in Table 2. RECOMMENDATIONS Based on the results of our field testing and soil classifications at the test location. we offer the following recommendations for stormwater infiltration design: At the test location INF-1 and INF-2 it is our opinion that in order to achieve the steady state flow rate obtained during our testing; the areas of infiltration galleries or other infiltration structures should introduce stormwater at approximately 36 inches below the existing ground surface elevation. For purposes of sizing the structures we recommend an ultimate application rate of 7.4 and 8.0 inches per hour, respectively. These recommendations should be reviewed by appropriate regulatory authorities before finalizing the details of any civil design. Tripp Engineering, P.C.

VAN DER VAART secretary TRACY DAVIS Direemr The Wilmington Regional Office received and accepted a State Stormwater Management Permit Application for Deer Crossing Phase 3 on October 11, 2016. A preliminary in-depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. Soils Report [per 15A NCAC 02H.1003(g)(7)]: Please provide the existing grade of the boring, the depth to the SHWT, and the resultant SHWT elevation. 2. Drainage Area [per 15A NCAC 0211.1003(g)(5) and 02H.1005(d)]: Please show the drainage area to the basin on the plans. 3. Design Option [per 15A NCAC 02H.1003(g)(7)]: I believe you are using Design Option #4 which does not require all of the design parameters if you can infiltrate the 10yr24hr storm. But, the routing sheet for the 10yr24hr storm discusses the 2.5 x volume option. Please clarify the intention and provide any additional data (such as the drawdown time for the I Oyr24hr storm). Please remember that a change to one number may have a domino effect on other numbers. Please check all plans, calculations and forms to ensure that the numbers are consistent throughout. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to January 13, 2016, or the application will be returned as incomplete. The return of a project will necessitate resubmission of all required items, including the application fee. If you need additional time to submit the information, please mail, email or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information, which shall be no later than 30 days past the original due date. The Division is allowed 90 days from the receipt of a completed application to issue the permit. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

ECEIVE JAN 13 2017 BY. 10/11/16 Stormwater & Erosion Control Narrative Deer Crossing Phase III New Hanover County, NC TE 12042 Deer Crossing Phase III is a residential site consisting of 39 si►igle-Famiiy Ints in New Hanover County, Parcel ID# R07900-003-035-000, owned by Wilson Ki. The project area is approximately 7.42 acres. No wetlands exist on the site. Deer Crossing Phase III proposes 39 single-family lots at 3,000 sf of impervious surface for each lot; 31,000 sf of asphalt roadway; 4,615 sf of concrete sidewalk; one (1) infiltration basin and utility extensions. The site has one (1) drainage area which is approximately 7.42 acres. The total impervious area for the site is 152,615 sf. The project will be treated by erosion control measures such as drop inlets with inlet protection, temporary silt fence, gravel construction entrance, and one (1) sediment basin as well as tree protection. One (1) infiltration basin provides sufficient storm water management to meet the State's 1.5" requirement and alternately sized for the 25-yr storm event and analyzed for the 50-yr storm event. Calculations have been provided to demonstrate that the ; %r 2 -hotir storm event liar, be lmiltralcii without discharging the system using an infiltration rate of one-half of the infiltration rate reported in the soils report, therefore waiving the State required off4in by pass and vegetated filter strip.
