Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Page 9 of 12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr state nc us/ncwetlands/strm~ide html. Provide a brief description of the proposed mitigation plan.

The lots w•it! tiont on standard NC DOT streets, with graded grass-lined ditches and shoulders. leach lot will he served by public water from Johnston County and wi1D have individual septic systems, approved by the Johnston County Environmental Health Deparinaent. The project is not located withirt an area that is defined as an F,nvirortmentally Sensitive Area, as shown on current reaps provided by Johnston County. The impervious area is below the allowable limit indicated in the Ordinance. The existins drainage patterns will remain, with the Overland runoff into unnamed tributaries to Big :A.rrn. 'These tributaries are considered "blue line" streams and will be required to have 50' riparian buffers on each side of the stream. The existing drainage feature downstream, the main stern of Big Arsn, is large enough to handle the additional runotfgenerated from this project, One roadway crossing will be analyzed downstream of the project. The crossing is on SR 1715. impervious areas, within the project area, will be limited to roadway construction and lot development.

Important maintenance procedures: - Immediately after the filter strip is established, any newly planted vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). - Once a year, the filter strip will be reseeded to maintain a dense growth of vegetation - Stable groundcover will be maintained in the drainage area to reduce the sediment load to the vegetation. - Two to three times a year, grass filter strips will be mowed and the clippings harvested to promote the growth of thick vegetation with optimum pollutant removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and may be allowed to grow as tall as 12 inches depending on aesthetic requirements (NIPC,1993). Forested filter strips do not require this type of maintenance. - Once a year, the soil will be aerated if necessary. - Once a year, soil pH will be tested and lime will be added if necessary. After the filter strip is established, it will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County). Records of inspection and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows.

Sullins, Director Division of Water Quality DWQ EXP# 07-1471 Johnston County On-Site Determination for Applicability to the Neuse Riparian Area Protection Rules (15A NCAC 2B .0233} -EXPRESS REVIEW PROGRAM Dear Mr. Pace: On September 1 1, 2007, at the request of Mr. Neal Floyd, Lia Myott conducted an on-site determination to review six stream features located on the subject property for applicability to the Neuse Buffer Rules (ISA NCAC 2B .0233). The features are labeled as "A" through "F", on the attached maps initialed by Lia Myott on September 17, 2007. The Division of Water Quality (DWQ) has determined that the following: • Feature "A" is a perennial steam and is therefore subject to the Neuse Buffer Rule on the property. • Feature "B" is at least an intermittent stream (an intermittenUperennial point determination was not conducted) but the feature is not shown on either the USGS Topographic map or the Johnston County soil survey map and therefore is not subject to the Neuse Buffer Rule, but is considered a jurisdictional water of the state. • Feature "C" is a perennial stream at the flag labeled "C1"but the feature is not shown on either the USGS Topographic map or the Johnston County soil survey map and therefore is not subject to the Neuse Buffer Rule, but is considered a jurisdictional water of the state. • Feature "D" is not subject to the Neuse Buffer Rule. No stream feature was observed. • Feature "E" is not subject to the Neuse Buffer Rule on the property or within 50 feet of the property boundary. • Feature "F" is an ephemeral stream and is therefore is not subject to the Neuse Buffer Rule. This on-site determination shall expire five (5) years from the date of this letter. Landowners or affected parties that dispute a determination made by the DWQ that a surface water exists and that it is subject to the buffer rule may request a determination by the Director. A request for a determination by the Director shall be referred to the Director in writing c/o Cyndi Karoly, DWQ 401 Oversight/Express Review Permitting Unit, 2321 Crabtree Blvd., Raleigh, NC 27604-2260. You must act within 60 days of the date that you receive this letter. Applicants are hereby notified that the 60-day statutory appeal time does not start until the affected party (including downstream and adjacent landowners) is notified of this decision. This determination is final and binding unless you ask for a hearing within 60 days. This letter only addresses the applicability to the buffer rules and does not approve any activity within the buffers. Nor does this letter approve any activity within Waters of the United States or Waters of the State.
