It is recommended that testing of the soil be conducted at least once or twice per year. Testing is to encompass pH measurements as well as heavy metal and toxin accumulation data. When soil pH exceeds an acidity of pH 5.5, limestone or another suitable alkaline agent should be added to the soil. Toxin laden soils should be removed and disposed of properly. The following table describes a typical maintenance schedule as recommended by the North Carolina Department of Environment and Natural Resources. Adherence to this schedule will prolong the operational life of the rain garden.

It is unclear whether this has been included on your plans. Please indicate the location of the grass buffer strip. The bio-retention area was designed in accordance with Bill Hunt's guidelines as described in the document "Designing Rain Gardens" published by the North Carolina Cooperative Extension Service. These guidelines suggest consideration of buffer strips for gardens where high TSS loads are expected Consideration was given to a grass buffer strip. However, dire to space limitations, a buffer strip was determined to be unfeasible. • You are reminded of the necessity of sequencing the installation of Research Triangle Park, NC sediment and erosion control measures to minimize the contamination Post Office Box 14005 of the planting soil with silts and fines. Sediment controls must be Research Triangle Park, installed around the area to be disturbed before grading, and around North Carolina 27709 the bio-retention area before the excavation of the trench/pit for the 2905 Meridian Parkway planting soil. Sands and fines clog the planting soil and impair the Durham, North Carolina 27713 functions of the bio-retention cell.

McADAMS COMPANY, INC. Ms. Cyndi Karoly May 9, 2005 Page Two Please indicate the Rational C Coefficient used for the Bio-retention design. The rain garden was designed to accommodate the first-flush volume as calculated using the Natural Resources Conservation Service Curve Number Method. Consequently, the Rational Method was not used in any design calculations. However, a composite Rational C of 0.7 would most closely reflect the drainage basin. Please indicate the size percentage (either 5% for bio-retention with sand under drain or 7% for bio-retention cells without sand under drain). Since the rain garden was designed for volume and not area, consideration was not given to size percentage. However, the surface area of the bio-retention area meets the 7% specification for cells without a sand filter. • Please indicate the inlet flow depth. The inlet flow depth is 8 inches at FES #1 (northeast) and 11 inches at FES #2 (southwest). • Please indicate the permanent pool elevation (i.e., the elevation of the orifice invert out). You are reminded that the ponding depth should not be greater than six inches. The bioretention area is typically dry. No permanent pool was provided. During rain events, the temporary pool reaches elevation 281.50 ft. This represents a ponding depth of 12 inches. This depth is Research Triangle Park, NC in accordance livith Bill Hunt's guidelines.

The DWQ has determined that your application is incomplete and/or provided inaccurate information as discussed below. The DWQ will require additional information in order to process your application to comply with the conditions?of the 401 Water Quality Certification. Please provide the following information so that we may continue to review your project. Additional Information: • Bio-retention Areas require a grass buffer strip (see p. 36 of the DENR Stormwater BMP Manual). It is unclear whether this has been included on your plans. Please indicate the location of the grass buffer strip. • You are reminded of the necessity of sequencing the installation of sediment and erosion control measures to minimize the contamination of the planting soil with silts and fines. Sediment controls must be installed around the area to be disturbed before grading, and around the bio-retention area before the excavation of the trench/pit for the planting soil. Sands and fines clog the planting soil and impair the functions of the bio-retention cell. Please revise your Erosion Control Notes and Construction Sequence to reflect these considerations. • Please indicate the Rational C Coefficient used for the Bio-retention design. • Please indicate the size percentage (either 5% for bio-retention with sand under drain or 7% for bio-retention cells without sand under drain). • Please indicate the inlet flow depth. • Please indicate the permanent pool elevation (i.e., the elevation of the orifice invert out). You are reminded that the ponding depth should not be greater than six inches. • Planting details appear to be missing from your plan. Please provide the following: 1. Planting schedule and specifications (see pgs. 55 and 63). 2. Planting soil guidelines (see pgs. 56 and 62). 3. Mulch details (p. 58). 4. Maintenance guidelines (p. 60). Please revise your Operation and Maintenance Agreement to reflect these guidelines. 401 oversight/ Express Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919.733.1786 /FAX 919.733-6893 / Internet: htto://h2o.enr,state.nc.us/ncwetlands One N Carolina aturally An Equal Opportunity/Affirmative Action Employer - 50% Recycled/l0% Post Consumer Paper SECU Louisburg Page 2 of 2 May 5, 2005 You have indicated that an under drain is provided.

It is recommended that testing of the soil be conducted at least once or twice per year. Testing is to encompass pH measurements as well as heavy metal and toxin accumulation data. When soil pH exceeds an acidity of pH 5.5, limestone or another suitable alkaline agent should be added to the soil. Toxin laden soils should be removed and disposed of properly. The following table describes a typical maintenance schedule as recommended by the North Carolina Department of Environment and Natural Resources.

STATE EMPLOYEES' CREDIT UNION • LOUISBURG, NC Final Design of Bioretention Area Proiect Description and Summary This document addresses stormwater impacts for the proposed commercial development of a State Employees' Credit Union building. The site is located at the intersection of NC 56 and US 401 in Louisburg, North Carolina. Proposed development on this site consists of a commercial building along with associated parking and drive aisles. A bioretention area was designed to function as the site's stormwater management facility. The proposed SECU site is a parcel of the Dixie Development Commercial Site draining to the Tar River Basin; a WS-V Nutrient Sensitive Water. The overall development was granted a state 401 Water Quality Certification and Authorization Certificate under condition that individual sites provide a stormwater management plan. Said plan must demonstrate 85% total suspended solids (TSS) removal for stormwater runoff exiting the site. Removal is to be via an approved NCDENR Stormwater Best Management Practice. The bioretention area proposed herein was designed in accordance with approved NCDENR standards. The state assumes that when bio-retention areas are designed, constructed and maintained properly, they will provide at least this standard of pollutant removal. The bioretention basin was sized to capture and treat the "first flush" of runoff from a 1" rainfall over the SECU site. This volume of water is assumed to contain the highest concentration of pollutants. The first flush volume is captured in the bioretention area (also known as a rain garden) and allowed to infiltrate into the soil. This process employs ® the rain garden plants and soil matrix in pollutant removal via absorption, microbial action, plant uptake, sedimentation and filtration (Designing Rain Gardens, Bill Hunt). Water flow in excess of the first flush is allowed to bypass treatment by way of a standard NCDOT drop inlet and grate. Additionally, when properly maintained, bioretention areas provide the added benefit of appearing as a natural component of the surrounding landscape. The planting plan provided for this rain garden was chosen for pollutant removal as well as aesthetic enhancement. Methodology: • The proposed site was determined to contain primarily HSG B soils from investigation of the Franklin County Soil Survey Sheet #10. An exhibit detailing this information has been included in this report. • The Natural Resources Conservation Service Curve Number Method was used to size the rain garden basin. The precipitation (P) used was 1 inch, with the Curve Number (CN) for directly connected impervious surfaces set at 98. Open areas were given a CN of 61, which assumes good open conditions in Hydrologic Group B soils. • Site topography was provided to The John R. McAdams Company, Inc. by O'Brien Atkins Associates P.A. 0 • The bio-retention area was designed in accordance with the guidelines provided • within the manual titled "Stormwater Best Management Practices " (April 1999) by NCDENR - Division of Water Quality. This analysis also uses design guidance provided by the North Carolina State University Stormwater BMP Academy held on October 7, 2003. • Details for the overflow structure of the rain garden are provided from Standard NCDOT Concrete Drop Inlet English Drawings. • The planting schematic for the rain garden is included on the construction drawing. Soil specifications for the basin are cited from the above-mentioned NCDENR manual. • U.S. Army Corps of Engineers HEC-HMS Version 2.2.2 was used to perform the 10-year and 100-year design storm pond routing calculations. • Haestad Methods PondPack Version 8.0 was used to compute the stage-discharge curve of the proposed stormwater management facility. This data was then input into HEC-HMS for routing calculations. • Rainfall data for the Raleigh-Durham region is from USWB Technical Paper No. 40 and NOAA Hydro-35. This data was used to generate a depth-duration- frequency table describing rainfall depth versus time for varying return periods in the RDU region. Rainfall depths from this table were then input into HEC-HMS for routing of the 10- and 100-year design storms. • The post-development time of concentration for the site watershed was conservatively estimated to be 5 minutes. • An anti-seep collar is provided along the proposed outlet barrel to guard against seepage along the barrel / soil interface. The location and size of the anti-seep collar was designed such that the flow length along the barrel increases by 15%. • A velocity dissipator is provided at the principal spillway outlet to prevent erosion and scour in this area. The dissipator is constructed using stone riprap underlain with a woven geotextile filter fabric. The filter fabric is used to minimize the loss of soil particles beneath the riprap apron. The dissipator is sized for the 10-year storm event using the NYDOT method. It is a' permanent feature of the outlet structure. • Since the 1" storm runoff is infiltrated into the ground, a level spreader was not provided at the facility outlet. Discussion of Results The bioretention area proposed for the State Employees' Credit Union site was designed in accordance with accepted NCDENR guidelines. It provides for treatment of the first flush runoff from a 1" rainfall. This treatment will provide 85% TSS removal from the runoff as well as curtailing its concentrated flow into Tar-Pamlico riparian buffers. The volume in question will instead infiltrate into the ground. This design is submitted as the stormwater management plan for the SECU site under the conditions of the Dixie Development 401 Water Quality Certificate.

BIORETENTION AREA STATE EMPLOYEES' CREDIT UNION LOUISBURG, NC Bioretention Area Operation & Maintenance Guidelines Planting Soil Care should be taken that the planting soil of the basin does not become overly acidic due to stormwater runoff. It is recommended that testing of the soil be conducted at least once or twice per year. Testing is to encompass pH measurements as well as heavy metal and toxin accumulation data. When soil pH exceeds an acidity of pH 5.5, limestone or another suitable alkaline agent should be added to the soil. Toxin laden soils should be removed and disposed of properly. The following table describes a typical maintenance schedule as recommended by the North Carolina Department of Environment and Natural Resources. Adherence to this schedule will prolong the operational life of the rain garden.
