This sheet shows the existing office building, paved parking area and gravel parking area. There are currently 51,530 square feet of existing impervious surface, most of which is gravel parking area formerly used for truck parking and loading. The site currently is not in use; however the office building is undergoing interior renovations. There are two existing storm drainage structures and two pipes on site that discharge into what appears to be an old sediment trap that was never removed. Purpose of Development: The property we purchased by Long Hill, LLC to be used in their trucking business. They are in need of a facility where they can securely store their equipment when it is not in use. A fueling tank and pump facility are also desirable. Proposed Conditions: The proposed site improvements include the addition of some passenger car parking for employees and a sizeable amount of new gravel parking for the truck storage area. A fence will be constructed around the facility to prevent unwanted entry. Impervious Areas: Some existing gravel will be removed (1,170 square feet) but the new gravel and paved surface areas result in a net increase of impervious surface of 27,236 square feet. A sand filter is designed to accept flow from; and treat the storm -water runoff from 38,690 square feet of gravel, roof top, and concrete surfaces. The area draining to the sand filter includes the diesel fuel tank and dispensation pump islands. To summarize, more impervious area is treated than is added and the most critical areas are included in the sand filter drainage area. Sand Filter: The sand filter is designed to accept flow from a drainage area of 63,960 square feet. A high flow diversion structure is placed between the forebay and the sand filte\u�R�111u1111111/' route high flows around the basin. ` ��`` N CARO Statistical Summary: Impervious Surface: 27,236 sf 8�At Net Increased Im p - 23 t ; z° Impervious surface treated in sand filter: 38,690 sf tre L 2. 2 tom, : � Sand Filter Drainage Area: 66,960 sf, �G�n��'yac' �.�� GAF -•.......•• Water Quality Volume Required: 2,385 sf, Water Quality Volume Provided: 3,OV/ is" T iCji`1`�����``�� 609 Stafford Pointe Court - Oak Ridge, NC 27310 - (336) 255-8395 0 Rational Method Runoff Calculation Q=C'I'A Q= Estimated design discharge (cfs) C= Composite runoff coefficient (unitless) 1= Rainfall intensity (inlhr) for the designated design storm in the geographic area of interest A= Watershed area (ac) Input Information: I = 5.5 Storm Event: 10 yr A = 1.537 Ac Calculate C: Description of Surface Rational Runoff Coefficient, C enter area (ac) C"A Unimproved areas 0.35 0.00 0.00 asphalttgravel 0.95 0.88 0.84 concrete 0.95 0.06 0.06 brick 0.85 0.00 0.00 roofs, inclined 1.00 0.09 0.09 roofs, flat (1 % or less) 0.90 0.00 lawns, sandy soil (<2%) 0.10 0.15 0.02 lawns, sandy soil (2-7%) 0.15 0.18 0.03 lawns, sandy soil (>7%) 0.20 0.00 lawns, heavy soil (<%) 0.15 0.00 lawns, heavy soil (2-5%) 0.20 0.00 lawns, heavy soil, steep (>7%) 0.30 0.18 0.05 wooded areas 0.15 0.00 Total: 1.537 1.08 avg.

This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important maintenance procedures: — The drainage area will be carefully managed to reduce the sediment load to the sand filter. — The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds six inches. — Once a year, sand media will be skimmed. — The sand filter media will be replaced whenever it fails to function properly after maintenance. The sand filter will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows.

This sheet shows the existing office building, paved parking area and gravel parking area. There are currently 51,530 square feet of existing impervious surface, most of which is gravel parking area formerly used for truck parking and loading. The site currently is not in use; however the office building is undergoing interior renovations. There are two existing storm drainage structures and two pipes on site that discharge into what appears to be an old sediment trap that was never removed. Purpose of Development: The property we purchased by Long Hill, LLC to be used in their trucking business. They are in need of a facility where they can securely store their equipment when it is not in use. A fueling tank and pump facility are also desirable. Proposed Conditions: The proposed site improvements include the addition of some passenger car parking for employees and a sizeable amount of new gravel parking for the truck storage area. A fence will be constructed around the facility to prevent unwanted entry. Impervious Areas: Some existing gravel wil I be removed (1,170 square feet) but the new gravel and paved surface areas result in a net increase of impervious surface of 35,385 square feet. A sand filter is designed to accept flow from; and treat the storm -water runoff from 37,257 square feet of gravel, roof top, and concrete surfaces. The area draining to the sand filter includes the diesel fuel tank and dispensation pump islands. To summarize, more impervious area is treated than is added and the most critical areas are included in the sand filter drainage area. Sand Filter: The sand filter is designed to accept flow from a drainage area of 63,069 square feet. A high flow diversion structure is placed between the forebay and the sand filter to route high flows around the basin. Statistical Summary: Net Increased Impervious Surface: 35,385 sf Impervious surface treated in sand filter: 37,257 sf Sand Filter Drainage Area: 63,069 sf, Water Quality Volume Required: 2,293 sf; Water Quality Volume Provided: 3,057 sf 609 Stafford Pointe Court - Oak Ridge, NC 27310 - (336) 255-8395 Green Mountain Engineering, PLLC Civil Engineering Consultants 1.275 Old Belt Way — Rural Hall, NC HSW REPORT Date: June 12, 2012 Site Inspection: The elevation below the stone in the bottom of the sand filter is 911.75 and the existing ground elevation in that area is below 910.00. A visual inspection of the area on April 17, 2012 revealed no indication of high seasonal ground water within one foot of the surface. All vegetation in the area is upland vegetation; therefore the highest seasonal ground water elevation is determined to be below the elevation 909.0. 609 Stafford Pointe Court - Oak Ridge, NC 27310 - (336) 255-8395 Y � ._ � ♦ .. � � ` l 1 _ '+ ' ' � ` '.

The April 1997 relocation of the mesic/thermic line in North Carolina and Virginia necessitated the establishment of the Tomlin series as a mesic counterpart. Tomlin soils are commonly associated with Clifford soils (fine, kaolinitic, mesic Typic Kanhapludults). Clifford soils formed in residuum weathered from felsic crystalline rock and have B horizons with hue of 5YR or redder with moist value of 4 or more. Tomlin soils formed in mixed felsic to mafic crystalline rock (primarily amphibolite) and have B horizons with hue of 2.5YR or redder with moist value of less than 4. Diagnostic horizons and soil characteristics recognized in this pedon: Ochric epipedon--the zone from 0 to 21 centimeters (Ap horizons) Argillic horizon --the zone from 21 to 145 centimeters (Bt and BCt horizons) Kandic horizon --the zone from 21 to 145 centimeters (Bt and BCt horizons) ADDITIONAL DATA: Characterization data are available from NRCS-Soil Survey Laboratory, Lincoln, NE.: Pedon (S06NC 197001) and (SO4NCO97020C). Note: Pedon SO4NCO97020C has a fine -loamy particle -size class and is an inclusion with the Tomlin series. All other soil qualities and properties are within the Tomlin series concept.

Overall, it looks great. 1. The surface areas and volumes for the sand filter and sediment chamber are not shown consistently between the supplement form, calculations, and sheet C-6. Based on the plans, it looks to hold the minimum required volume, but I need to verify the numbers for putting them in the permit. The numbers on the plans appear correct just from scaling the drawings. If that's the case, it should just require revising the calcs and supplement. 2. To verify, based on the notes in detail 3 (sht. C-6), what is the total BUA on the property post -construction. 3. As we discussed earlier, this facility will also need to apply for coverage under NCG080000 (NPDES industrial sw). That said, it will not affect issuance of this state sw permit (SW4120604). Please let me know if you have any questions. Thanks Robert ID.
