applicant proposes to improve flooding issues experienced by local property owners ad�acent to a northern un named tnbutary to Hewletts Creek � ` C�ty of Wilmington Wisteria Clearbrook Drainage Improvement Page 2 9 PROJECT DESCRIPTION The pro�ect site is within an existing un named tnbutary to Hewletts Creek which is located between the ma�or traffic thoroughfares of Oleander Drive and Greenvdle Loop Road m the City of Wilm+ngton New Hanover County To locate the sites from Oleander Drive (NC H�ghway17) turn onto Greenville Loop Road and travel west approximately 2 3 miles Turn nght onto Clearbrook Dnve �ust before the bridge that crosses Hewletts Creek and travel approximately 0 1 mdes north until you reach Patncia Dnve Turn left onto Patricia Dnve untd you reach a vacant lot currently owned by New Hanover County that is located ad�acent an existing stream which flows under Patricia Dnve towards Hewletts Creek to the south This location is within the lower portion of the pro�ect site The pro�ect site consists of the existmg un named tnbutary to Hewletts Creek which currently consists of approximately 6 500 Imear feet of �unsdictional perenrnal stream This distance of stream also includes existmg culvert lengths that are currently located under existing road crossings throughout the pro�ect area Each stream reach was defined by boundmg downstream and upstream of existmg road culverts For the purposes of site assessment and design ob�ective development the application has spiit the pro�ect stream into eight (8) reaches which originate from Reach 1 Patncia Dnve to C�earbrook Drive in the lower end of the pro�ect area to Reach 8 Gardenia Lane to Verbena Drive in the upper end of the pro�ect area respectively The pro�ect occurs entirely within a residential area that mcludes recently constructed homes mid century smgle family homes and mobde homes The pro�ect area is located in a low energy sandy system confined by urban development which appears to encroach and constrict the active floodplain The lower pro�ect location below Patricia Drive withm Reach 1 includes the ma�onty of the tidally influenced area of the pro�ect which is due to the channelized stream and its proximity to Hewletts Creek and the ad�acent coastal wetlands During an on site meeting on June 9 2010 the NCDCM flagged the upper limits of coastat wetlands and the normal high water (NHV1n boundanes It was determmed that the NHW boundary is located below Patncia Drive within this stream and above the upper limits of the coastal wetland boundary as indicated on Appendix 2B Due to the shading affect from the tree canopy and brush a�ong the banks of the stream this area was void of the presence of coastai wetlands Located on the banks of the channelized stream were existing spoil piles that appeared to be within the §404 Wetiands and the fringe of the upper coastal wetlands boundary Downstream where the stream opens into the creek the vegetation transitions into the upper limits of coastai wetlands which consist primarily of Black Needle Rush (Juncus roemar�anus) Bulrush (Sc�rpus spp ) Saw Grass (Clad�um spp) and Cat tail (Typha spp) The coastal wetlands transitions to an area of low marsh towards Hewletts Creek to the south which consists pnmarily of Smooth Cordgrass (Spartrna alterniflora) The ma�ority of open space withm the pro�ect area is forested The USACE issued a Jurisdictional Determination (JD) on May 25 2010 on the entire stream channel and ad�acent wetlands located within the pro�ect area (SAW 2009 00127) (See Sheets EX 1 through EX 11 and Appendix 2A) The Wilmington/New Hanover County 2006 Land Use Plan ciassifies ad�acent waters and marsh as Conservation and the ad�acent high ground portion of the pro�ect area as Resource Protection The waters of Hewletts Creek are classified SA by the Division of Water Quality They are designated as a Primary Nursery Area (PNA) by the N C Division of Marine Fisheries and they are CLOSED to the harvest of shellfish PROPOSED PROJECT The applicant proposes to improve flooding issues experienced by local property owners ad�acent to a northern un named tributary to Hewletts Creek The City contracted the agent Kimley Horn and Associates Inc to develop an extensive Feasibility Study m November 2009 to assess the floodmg issues m this area and propose solutions ' City of Wilmington W�steria Clearbrook Drainage Improvement Page 3 The agent along with the City requested a scoping meeting which was held at the Wilmington Regional Offrce (WiRO) on May 27 2010 to d�scuss the proposed pro�ect with mterested rev�ew agencies that included NCDCM NCDWQ NCDLR NCWRC NCDMF and the USACE representatives The agent and City also held two (2) public meetings for the ad�acent

PERMIT APPLICATION NARRATIVE Wisteria-Clearbrook Drainage Improvements October 2011 Wilmington,North Carolina EXECUTIVE SUMMARY Introduction— The Wisteria-Clearbrook Drainage Improvement Project area is located within a heavily urbanized portion of the City of Wilmington. The project area is between the major traffic thoroughfares of Oleander Drive and Greenville Loop Road (See Figure 1). The project stream is the northern tributary to Hewlett's Creek. The City of Wilmington desires to improve drainage and water quality as well as secure maintenance access along the project stream corridor. The predominant issue associated with the project stream is flooding along the primary outfall to the stream and in the neighborhoods surrounding the project area. Some roads within the neighborhoods become inundated during large storm events, often several times per year. Additionally, the project area was identified in the City's 1998 Annexation Area Stormwater Master Plan as also having maintenance and water quality issues. Hewlett's Creek is classified as SA; HQW by the North Carolina Division of Water Quality (NCDWQ) which should support commercial shell fishing and other uses. However, Hewlett's Creek has experienced algal blooms, low dissolved oxygen, and fecal coliform bacteria which have resulted in it being listed as "impaired" according to DWQ's 303(d) list. Flood Attenuation Approach - Due to the complex nature of the drainage system, an extensive Feasibility Study (November 2009) was developed by Kimley-Horn for the City in order to assess the flooding issues and propose solutions. Two public meetings were held and all adjacent landowners were invited via mail. Input and comments were solicited during the meetings - especially flooding information- that were used with other information to calibrate the flood models. Also, as part of the development of the proposed solutions (i.e. preliminary plans), the City met with the Division of Coastal Management (DCM), the US Army Corps of Engineers (USACE), the Division of Water Quality (DWQ), the Division of Marine Fisheries (DMF), Wildlife Resources Commission (WRC), and the Division of Land Resources (DRL) on May, 27tn, 2010 for a pre-application meeting to identify any issues and concerns of these agencies. There have also been various onsite meetings with the USACE, DCM, DWQ, DMF, and WRC. These meetings with the agencies were intended to discuss the proposed project solutions. Design approaches analyzed culvert replacements options, flood attenuation options, floodplain re- establishment, stream profile adjustments, off-line storage, and other options and gauged their affect on flood water elevations for the 25-year, 100-year, 25-year future, 100-year future, and surge design storm events. All references to storm return intervals refer to the discharge from a statistical 24-hour rain event at the given return interval. The primary design objective - in addition to improving flood attenuation - is to improve the water quality and habitat functions within the stream/wetland system. The water quality approach is discussed below. Water Quality Approach— As part of the Feasibility Study, an extensive site evaluation was conducted to assess environmental conditions and functions of the stream and wetland corridor and to identify opportunities for water quality and habitat improvements. The site evaluation and analysis included: site survey, records research, stream classification and reach analysis, wetland and stream delineation, biological PERMIT APPLICATION NARRATIVE Wisteria-Clearbrook Drainage Improvements October 2011 Wilmington,North Carolina evaluation, and watershed analysis. Also, there were several on site meetings with the agencies listed above. As previously mentioned, Hewlett's Creek is currently listed as impaired. The site evaluation also identified existing physical impairments to habitat and ecological function such as stream relocation, channelization, and historical wetland and salt marsh fill. Based on the results of the flood modeling and site evaluation, a total of twenty-eight (28) design approach alternatives were considered. Items such as environmental impacts, avoidance and minimization, cost versus benefits, constructability, and potential infrastructure conflicts and constraints were compared to identify the preferred alternative. Alternatives that would have resulted in higher amounts of permanent environmental impacts, such as significant culvert extensions and temporary impoundments, were rejected. The majority of the proposed impacts are temporary in nature and are intended to improve or restore the natural functions of the historically impacted areas. Additionally, the project includes measures such as the re-creation of 3.9 acres of salt marsh wetlands by removing historic fill for residential lots and the removal of historic spoil piles created by the channelization of the stream. Also, all channel work will be done using natural channel design techniques to improve and re-establish habitat. In addition to the above, impacts in certain areas along the stream corridor deemed to have the highest water quality and habitat functions have been avoided and minimized. Additionally, some of these areas are to be acquired or preserved as part of this project in order to protect water quality functions. Easement and Land Acquisition Approach— One of the project goals is to establish access along the entire project corridor for maintenance purposes. However, this object was expanded to include obtaining easements or properties to restore or preserve ecological functions. Such opportunities include purchasing a lot at the corner of Shuney and Brittain and using land purchased by the County as part of FEMA buyouts to re-create salt marsh. Selected Alternative— Two very similar alternatives were identified as part of the Feasibility Study. Both resulted in roughly the same impacts. The proposed plan is similar to both these alternatives, but includes some variations due to constraints identified as the design progressed. Alternatives that included impoundments or significant culvert extensions were eliminated because of the environmental impacts associated with them. The plan selected was chosen because it meets all three of the City's desired criteria - flood attenuation, water quality improvements, and acquisition of maintenance access. The project also includes the acquisitions that will preserve higher functioning stream and wetland reaches along the project corridor. The City's goal is that the project will improve water quality as well as flooding. The City has taken and is proposing significant measures to meet the goal of improving water quality. Proposed Impacts— As stated above, the majority of the proposed impacts are temporary and have a goal of improving water quality and ecological function as well as flooding. There are no proposed impacts to coastal wetlands or impacts within the NHW boundary. Most permanent channel impacts are to roadside drainage channels and not streams. Permanent wetland and stream impacts are 0.0016 acres and 283 feet respectively. Temporary wetland and stream impacts are 0.7 acres and 4107 feet, respectively.

It is proposed that these goals will be achieved through a combination of efforts, which include culvert replacements, easement and land acquisition, the use of natural channel design techniques, wetland creation, offline stormwater BMPs, and stormwater detention practices. The Project is located within the City limits of Wilmington, North Carolina, south of Oleander Drive (U.S. Highway 76) and west of Greenville Loop Road, as shown in Section 5.0, Figure 1 Project Vicinity Map. The Project occurs entirely within a residential area that includes recently constructed homes, mid-century single family homes, and mobile homes. The majority of open space within the Project area is forested. The Project occurs along an unnamed tributary of Hewletts Creek identified by the North Carolina Division of Water Quality (NCDWQ) as Stream Index #18-87-26. Hewletts Creek is located in the Cape Fear River Basin, Hydrologic Unit Code 03030001. The Project tributary is located within a topographic depression that appears on the USGS 1:24,000 scale Wrightsville Beach, North Carolina Quadrangle Map (USGS, 1970), refer to Section 6.0, Figure 2 USGS Quad Map of this report. Downstream of the Project area, Hewletts Creek is classified as SA (Market Shellfishing, Salt Water), HQW (High Quality Waters). Hewletts Creek is included on the 2008 Draft 303(d) list as impaired due to excessive levels of Fecal Coliform. The watershed that drains to the Project area is approximately 1000 acres in size, with land uses including commercial/industrial (±10%), open space/forested (±10%), and medium density residential (±80%). Refer to Section 5.0, Figure 2 Project Overall Aerial Map with Drainage Basins. The watershed includes commercial areas along Oleander Drive, residential neighborhoods of varying density, and an electrical substation surrounded by residential areas. Approximately the lower third of the Project area is located within the 100-year floodplain, as shown on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM), as outlined in Section 5.0, Figure 7 FEMA Floodzone Map. Additional flood modeling was conducted by the City, which mapped additional limits of potential 100-year flooding (above FEMA mapping) to include most of the Project area. As part of the Feasibility Study, this information was updated as shown in Section 6.0, Table I. Section 5.0, Figures 4a-b USDA/NRCS Soil Survey Map displays the soil units as mapped in the New Hanover County Soil Survey (USDA, 1977). Based on mapping and field review, large sections of the Project tributary appears to have been substantially modified in the past, either through dredging or relocation. Additionally, the in- flowing drainage network of pipes and ditches appear to lack consistent size and inter- connectivity. It is likely that this historic manipulation has also affected the extent and function of wetlands and other natural systems along the stream corridor. Also, based on the NRCS Soil Survey map areas along the lower portion of the project appear to have been filled for house construction. ❑�❑ Kimley-Horn � antl Associates,Inc. 2.0 SITE ASSESSMENT The Project stream is approximately 6,500 linear feet (LF) in length (including culvert lengths). For the purposes of site assessment and design objective development, the Project stream has been split into eight (8) reaches. Each stream reach is defined by a bounding downstream and upstream road culvert, which in most cases define a significant geomorphic or hydraulic change in the characteristic of the stream channel. The eight reaches are defined by the respective downstream and upstream road crossings as described below: Reach 1— Patricia Drive (a nd below) to Clearbrook Drive (Approximate Length—880 LF) Reach 2—Clearbrook Drive to Shuney Street (Approximate Length—730 LF) Reach 3—Shuney Street to Brittain Drive (Approximate Length—300 LF) Reach 4— Brittain Drive to Dogwood Lane (Approximate Length— 1150 LF) Reach 5— Dogwood Lane to Weeping Willow Road (Approximate Length—470 LF) Reach 6—Weeping Willow Road to Ruxton Way (Approximate Length— 1080 LF) Reach 7— Ruxton Way to Gardenia Lane (Approximate Length—630 LF) Reach 8—Gardenia Lane to Verbenia Drive (Approximate Length—700 LF) 2.1 Records Research A variety of information was gathered in order to evaluate aspects of the Project. Information gathered included GIS data and other City records. These records were evaluated and used to develop the Project alternatives and flood model. Preliminary coordination the North Carolina State Historic Preservation Officer (SHPO) and the Office of State Archaeology (OSA) revealed some concerns in the area around Weeping Willow Road. It is assumed that final coordination will occur as part of the CAMA application process. In addition to the above, it is necessary that information concerning the occurrence of federal and state protected species for New Hanover County be obtained from the US Fish and Wildlife Service (USFWS) list of endangered species, threatened species, federal species of concern, and candidate species for New Hanover County, North Carolina, and from the North Carolina Natural Heritage Program (NCNHP) database of protected species and unique habitats. For a full report regarding the above mentioned research refer to Section 7.0, Appendix 6 Natural Resources Report and Addendum. 2.2 Survey A survey of the Project area was conducted by W.K. Dickson, Inc. and completed in early 2009. The survey was conducted to include structure locations, tree sizes, species and location, utility locations, type and easements, roadway boundaries, locations and elevations, existing 1-foot topography, the existing 100-year floodplain boundary, wetland boundaries, all drainage features (stormwater culverts, pipes, headwalls, streams, ditches, etc.), finished floor elevations ❑�❑ Kimley-Horn � antl Associates,Inc. (FFE), property boundaries and information, and location and elevations of crawl space vents and HVAC units. Throughout the Project corridor the FFEs of the habitable structures located within the Project area vary. Some frequently flooded properties provide as little as a half-foot to 2 feet of topographic relief between the top of bank of the stream and the structure's FFE. Habitable Structures of concern are the two single family homes located below Patricia Drive, the single family home on the left bank downstream of Clearbrook Drive (418 Clearbrook Drive), the single family home located on the right bank upstream of Clearbrook Drive (413 Clearbrook Drive), the two single family homes located south of Plover Court (5522 and 5523 Plover Court), and the single family home on the left bank downstream of Ruxton Way (5704 Ruxton Way). According to the City of Wilmington staff (City staff), these properties report flooding during large storm and localized thunderstorm events. The habitable structures located within close proximity to the stream that do not experience flooding are often elevated on pilings or fill. In such instances the property may experience flooding, but damage to the structure may not occur. All street right-of-ways within the Project corridor are public with the exception of Ruxton Way. Approximately the lower third of Reach 1 and a majority of Reach 8 exist within the public right- of-way. Utility easements within the Project corridor generally parallel roads, occasionally crossing the stream. There are utility easements along the lower third of Reach 2 and along Reaches 5, 6, 7 and 8. Additionally, drainage easements intersect the Project corridor. Even with the numerous and various easements located within the Project corridor, significant reaches of the existing stream are located on private property. There are a number of "private" utilities (in addition to water and sewer) that were identified within the Project corridor. These include telephone, gas, and electric. 2.3 Wetland Delineation and Natural Resources Assessment Natural resources assessments and jurisdictional determinations (JD) conducted in two phases. The USACE signed the JD map on May 25, 2010 (Appendix 2A). Subsequently, DCM located the elevation of the NHW and Coastal Wetland boundary during the site visit on 6/9/2010. It is important to note that an original, preliminary extent of CAMA jurisdiction was made prior to May 25, 2010. The USACE signed JD map only reflects the preliminary CAMA determination and not the final determination made on 6/9/2010. Therefore, the JD map signed by the USACE does not correctly identify the extent of CAMA jurisdiction (which is shown in the USACE map to be just above Clearbrook Drive). Appendix 2B correctly identifies the extent of CAMA jurisdiction (i.e. the final determination) made on 6/9/2011 which does not extend above Patricia Drive. The elevation of the NHW location was determined by the surveyor to be approximately 0.4 feet based on mean sea level (MSL). A 0.4 foot contour (MSL) was generated and used to determine the NHW line (shore line). The mean high water (MHW) was derived from NOAA Tide Gauge at Wrightsville Beach, NC Station ID: 8658163. It is presented on the Patricia Drive area plan sheets in parentheses behind elevation callouts that are relative to MSL (see CAMA Permit Drawings). The AEC and 30-foot exclusion zone were then determined based ❑�❑ Kimley-Horn � antl Associates,Inc. on a 75-foot and 30-foot offset, respectively, from the NHW line. Additionally, a small amount of wetland identified on the JD map as 404 Wetland was determined by DCM to be coastal wetland. The overall wetland boundary did not change and the areas are not to be impacted as part of the Project in any event (Appendix 2B). For a full report regarding the above mentioned delineation and delineation mapping refer to Section 7.0, Appendix 6 Natural Resources Report and Addendum. The Endangered Species Act (ESA) of 1973 (16 U.S.C. 1531-1943) mandates that federal agencies ensure that any actions authorized, funded, or carried out by that agency do not jeopardize the "continued existence" of listed species or result in the destruction or adverse modification of critical habitat (16 U.S.C. 1536). The U.S. Fish and Wildlife Service (USFWS) is the federal agency that is responsible for ensuring that the provisions of the Endangered Species Act are met. Additionally, North Carolina laws grant limited protection to rare plants and animals that are endemic to the state or whose populations are in severe decline. For a full report regarding the above mentioned delineation refer to Section 7.0, Appendix 6 Natural Resources Report and Addendum. 2.4 Stream Geomorphic Assessment Kimley-Horn conducted geomorphic surveys and visually assessed the stream materials to varying degrees on all eight (8) reaches within the Project area. Rosgen Level II and III stream assessments were performed in reaches 2 and 6. Additionally, North Carolina Division of Water Quality (NCDWQ) Stream Identification Forms were completed for each reach during the environmental features survey. Refer to Section 7.0, Appendix 4 Morphological Cross-sections and Profile Data for the surveyed cross-sections, and longitudinal profiles. Refer to Section 5.0, Figure 5a-c Stream Reach Maps for reaches associated with the geomorphic analysis. Table 1 summarizes the morphological results of the geomorphic survey. Table 1: Summary of Stream Morphological Data Assessment Drainage Entrench.

During the geomorphic site assessment typical riffle and pool cross-sections are taken along the studied reaches. The typical riffle cross-sections were used to determine the approximate bankfull area, width, and depth of the stream reach. These parameters are measured from the bankfull indicators on the riffle cross-section, which correlate to the channel forming flow for the studied stream reach. The bankfull area, width, and depth gathered at the studied site can then be compared to the reference data for the Coastal Rural Regional Curve for the upstream drainage area. The Coastal Rural Regional Curve uses a power function regression equation developed from gathering similar bankfull data on reference reaches throughout the coastal plain. In addition to the reference curve comparison, several ratios have been developed as part of the Rosgen Classification System to assist in classifying stream type, and assessing stream stability. Table 1 above utilizes a portion of these ratios to provide an overview of the existing geomorphic conditions of the Project stream reaches. The Rosgen Classification System defines Stream Type by describing channel characteristics (A-G) and substrate characteristics (1-6). For the Coastal Plain, more favorable channel characteristics would mostly be categorized as a Rosgen "C" or "E" channel type. "C" and "E" channel types are single threaded channels, tending to meander within their floodplain, and having regular access to a wide floodplain. Less favorable channel characteristics would be categorized by a Rosgen "B", "F", or "G". These channel types tend to be confined to deep valleys, and have limited access to a wide floodplain. Entrenchment Ratio is a measure of the streams bankfull width against the width of the flood- prone area. The flood-prone width is measured in the field at a height that is equal to two times the bankfull depth of the stream channel. "C" and "E" channel types typically have entrenchment ratios greater than 2.2, which associates the flood-prone width to be greater than twice the bankfull width. Due to the flat terrain found within the Project corridor many of the reaches have wide flat floodplains at a height equal to two times the bankfull depth. As seen in Table 1 on the previous page. "B", "F" and "G" channel types tend to be confined within a larger ditch in which the width of the larger ditch does not vary much from the bankfull width to the top of the ditch. The dredged and channelized streams fall into these categories. Width-to-depth ratio helps to distinguish between the types of channels, and is defined as the bankfull depth divided by the mean bankfull depth of the channel. "E" channel types have width-to-depth ratios less than 12. While "C" channel types have width-to-depth ratios greater than 12. Therefore, "C" channel types are wider and shallower than an "E" channel type, which is more narrow and deep. The other width-to-depth ratios for the common channel types found throughout the Project corridor are as follows: B greater than 12, F greater than 12, and G less than 12. Sinuosity (K) defines the streams meander through its floodplain, and is defined by the stream length divided by the floodplain length. The lowest value possible for sinuosity is a value of 1.00, as the floodplain cannot be longer than the stream. A value of 1.00 indicates that the stream flows straight with the floodplain, which is typical of ditched or channelized streams. As sinuosity increases the slope of the stream channel decreases, and can effectively reduce the energy in a stream system. More natural stream systems found in the coastal plain tend to have sinuosityvalues between 1.2 and 1.5. ❑�❑ Kimley-Horn � antl Associates,Inc. The following summarizes the geomorphic conditions of the stream reaches found onsite: Reach 1 includes a majority of the tidally influenced area of the Project tributary. During field visits Reach 1 was observed to have variable diurnal flow direction and water surface elevations. This tidal influence restricts flow through the 36" CMP beneath Patricia Drive. Refer to Section 7.0, Appendix 3 - Site Photographs, Photograph 1. Also, the lower portion of Reach 1 appears to have excessive sedimentation. Although tidally influenced, bankfull indicators were present throughout the reach. A total of four (4) cross-sections and one (1) longitudinal profile were surveyed for Reach 1 as part of the geomorphic analysis. Two (2) cross-sections and the longitudinal profile were taken along the stream section flowing parallel to Sharon Drive (Photographs 2, and 3), and two (2) were taken along the stream section flowing between the existing wetland and houses on Clearbrook Drive (Photographs 4, and 5). Reach 1 classifies as a Rosgen C5 due to its moderate width to depth ratio, and the reach's ability to access its' wide floodplain (moderate entrenchment ratio). However, this stream reach lacks the sinuosity, and riffle-pool sequence typical in a C5 channel. The longitudinal profile revealed a low pool-to-pool spacing, between 1.5 and 2.5, which is more typical for a straightened stream channel. Reach 1 scored a 35 and a 36.5, classifying it as perennial on the NCDWQ Stream Classification Form. The channel material observed in Reach 1 was mostly sand with some silt deposition and accumulation. Reach 2 from Clearbrook Drive to Shuney Street appears to have been partially straightened or dredged, most notably immediately upstream of Clearbrook Drive, where the stream flows in a narrow ditch between houses for about 220 feet. Just above this ditched section, the stream begins to meander and exists in a relatively natural state surrounded by wetlands. It is evident that flooding in this section of the Project occurs regularly, and several of the surrounding residences are on raised foundations. Reach 2 may also experience occasional tidal influence just upstream of Clearbrook Drive (Photograph 6). The natural portions Reach 2 were used as a reference coastal, urban stream for natural channel design parameters. Two (2) cross-sections and a longitudinal profile were surveyed along this section of stream (Photograph 7). Bankfull indicators were strong and were consistent with the Coastal Rural Regional Curves for a drainage area of 0.64 square miles. Reach 2 classifies as a Rosgen E5 channel due to its low width to depth ratio, and the reach's ability to access its' wide floodplain (moderate entrenchment ratio). The sinuosity through the entirety of Reach 2 is 1.09; however, this number is slightly skewed by the ditched and straightened section. The reference section produces a sinuosity closer to 1.12. The longitudinal profile produced a riffle-pool sequence and meanders typical of a wooded meandering E5 channel with a pool-to-pool spacing between 1.6 and 4.7. The reach is considered perennial and is fed from the surrounding urbanized watershed. Reach 2 received a score of 48 using the NC Stream Identification Methodology. The channel material observed in Reach 2 was mostly sand. Reach 3 exhibits the most natural characteristics of all the reaches in the Project corridor. The evaluation produced geomorphic ratios similar to Reach 2. Just upstream of Shuney Street approximately 50 feet of stream exists within the fence line of a private resident (Photograph 9 and 10). Upstream of the private residence, the remainder for Reach 3 exists within a wooded buffer. The stream has close to reference reach quality pattern, dimension and profile through this area, and the riparian buffer remains intact, as shown in Photograph 11. Two (2) ❑�❑ Kimley-Horn � antl Associates,Inc. geomorphic cross-sections were taken along Reach 3. Bankfull indicators existed at the top of bank suggesting frequent flooding of the surrounding buffer. Bankfull indicators for Reach 3 were slightly less than the Coastal Rural Regional Curve suggests for a drainage area of 0.62 square miles. Reach 3 classifies as a Rosgen C5 channel due to its moderate to high width to depth ratio of 13.9, and it being slightly entrenched. This reach of stream received a score of 49.5 using the NC Stream Identification Methodology. The channel material observed in Reach 3 was mostly sand. Much of Reach 4 appears to have been relocated or straightened and impacted by residential development. There are locations along the stream where structures have been constructed within or immediately abutting the stream bank, including bulkheads, bridges, and driveway culverts (Photograph 13). As a result, the natural hydrology of this section of stream has been affected. Yard maintenance has also led to the removal of the riparian buffer down to the stream bank along several stretches. Two (2) geomorphic cross-sections were measured along a forested and less impacted section of Reach 4 just below the Dogwood Lane (Photograph 14). Bankfull indicators were present and produced results slightly smaller than the Coastal Rural Regional Curve would suggest for a drainage area of 0.59 square miles. The geomorphology observed in the less impacted section of stream classifies as a Rosgen E5 channel. During the visual assessment of Reach 4 Rosgen G and F channel types were also observed. This reach of stream received a score of 36 using the NC Stream Identification Methodology. Sand was the channel material observed throughout Reach 4. Reach 5 has been straightened. Houses have been built close to both sides of the stream, with little floodplain or riparian buffer present, as shown in Photograph 16. A majority of the surrounding floodplain for Reach 5 consists of maintained and grassed residential lawns. Reach 5 is hydraulically obstructed by an undersized and mostly buried 24" CMP culvert passing under the cul-de-sac of Plover Court. Reach 5 floods often, over topping Plover Court, and inundating two of the low lying houses at the end of the cul-de-sac (Photographs 17, and 18). Bankfull indicators were not identifiable during the field assessment due to the historical impacts from channelization, and continued residential maintenance. Two (2) cross-sections were measured near Plover Court. The cross-sections were compared to the Coastal Rural Regional Curve and bankfull dimensions were generalized based on the appropriate cross-sectional area associated with a drainage area of 0.44 square miles. From this methodology the cross-section for Reach 5 classifies as a straightened and modified Rosgen E5 channel. The channel is slightly entrenched with a low width to depth ratio. Reach 5 received a score of 32.5 using the NC Stream Identification Methodology, and is a sand dominated system. Reach 6 appears to have been historically relocated, straightened, and channelized. The land surrounding Reach 6 is mostly undeveloped. Side cast spoil piles line both sides of the reach. The entrenched nature of the stream limits its ability to access its floodplain. Even with the streams inability to access the surrounding floodplain, there is little evidence of excessive erosion. This is most likely a result of the streams low average stream slope of 0.0018 ft/ft and heavily vegetated banks. A typical view of this reach is shown in Photograph 20. Two (2) geomorphic cross-sections and a longitudinal profile were measured on Reach 6 just downstream of Ruxton Way. Bankfull indicators were not visible during the field assessment, and are not evident in the cross-sections due to the substantial, historical impacts to the reach. ❑�❑ Kimley-Horn � antl Associates,Inc. Based on a visual assessment, and the deep, entrenched nature of the system, Reach 6 classifies as a Rosgen G5 channel. Reach 6 received a score of 27.5 using the NC Stream Identification Methodology suggesting it is an intermittent stream. Ultimately, the channel appears to be perennial, and the low score was attributed to the lack of natural geomorphic features caused by the ditching. The channel material observed in Reach 6 was mostly sand. Reach 7 is a large ditch with yards backing up to the stream on both sides. The ditch appears to have been more recently excavated, and is large enough to carry expected storm flows. As a result, it is not expected that overbank flooding occurs along this reach, with the possible exception of the area immediately upstream of Ruxton Way where the ditch becomes shallow. A partially blocked 30" CMP currently runs under Ruxton Way, and acts as a hydraulic barrier for Reach 7 (Photograph 21). Two (2) geomorphic cross-sections were measured in the middle of this reach. It appeared as Reach 7 is aggrading as a result of the blocked culvert at Ruxton Way (Photograph 22, and 23). Bankfull indicators were not observed during the field assessment. Based on a visual assessment, and the deep, entrenched natural of the system, Reach 7 classifies as an "unnatural" Rosgen B5 channel. This reach of stream received a score of 33 using the NC Stream Identification Methodology. The channel material observed in Reach 7 was mostly sand and some silt deposition. Reach 8 has been recently excavated. Houses are located behind a narrow vegetated buffer on the east side of the ditch, and South 58t" Street abuts the ditch to the west. The ditch is large and appears to provide adequate capacity to carry expected flows (Photograph 26). Water is standing in the bottom of much of the lower sections of the reach, with aquatic vegetation occurring in areas. Moving upstream the channel becomes smaller (to a point that it appears to lose stream characteristics), is piped through driveway culverts, and is completely culverted through sections (Photographs 27, and 28). Two (2) geomorphic cross-sections were measured on Reach 8 just downstream of Ruxton Way. Bankfull indicators were not observed during the field assessment, and are not evident in the cross-sections due to the substantial, historical impacts to the reach. Based on a visual assessment, and the deep, entrenched natural of the system, Reach 8 varies between a Rosgen B5 and G5 channel. The reach received a score of 30.5 using the NC Stream Identification Methodology. The channel material observed in Reach 8 was mostly sand. Refer to Section 7.0, Appendix 3 Natural Resources Report and Addendum for additional information regarding each of the eight (8) Project stream reaches. 2.5 Existing Culvert Conditions The existing culverts vary significantly in size and flow capacity. Culverts sizes range from a 24- inch culvert in the middle of the Project (Plover Court) to a 72-inch culvert at the upper end (Gardenia). A majority of the Project culverts are corrugated metal pipe (CMP) with a few of the more recently installed culverts being reinforced concrete pipe (RCP). Conditions also vary from one road crossing to another. Several culverts are partially blocked by sediment accumulation, others have been damaged and bent at the entrance, and some are corroding. ❑�❑ Kimley-Horn � antl Associates,Inc. For the most part, the older residential areas have smaller sized culverts with many that are deteriorating. These culverts were most likely installed while the watershed was less developed and the flow through the channel was much less. Over the years the watershed has become more developed and the flow through the channel has increased, as such, more recent developments have larger sized culverts. It is also possible that less stringent regulation involving culvert flow capacity existed during the construction of the older residential developments. Refer to Table 2, on the next page, for a summary of the existing culvert conditions and design capacity. Table 2: Existing Culvert Capacity and Condition Existing Approx. Road Crossing Ex.

CAMELIA LANE 24 CMP 28 <2-year Poor physical condition. Damaged at entrance. *Refers to the discharge from 24 hour rain event from the given storm return interval. The culvert capacities in the Table 2 were determined using inlet control nomographs for the culvert material type. Headwater depths were calculated using the difference between the culvert's upstream invert elevation and the surveyed road crest. Culverts were assumed to have full flow capacity. Therefore, sedimentation and deformation at the entrance of the culvert were not considered. Storm discharge peaks were determined using the National Flood Frequency Programs Regional Regression Curves for the urban coastal plain. The Regional Regression Curve calculates the peak discharge based on the size and cover of the upstream drainage area. Timing and flow storage is minimally considered in this calculation. Based on the current compositions of the upstream watersheds, many of the culverts located within the older residential areas convey less than the 2-year storm. Even the more recently installed RCP culverts only convey between the 2-year and 10-year storm event. The current standard within the City of Wilmington is to convey the 25-year storm event within road culverts. 3.0 Project Description 3.1 Purpose and Need/Project Approach The City intends to achieve three goals as part of the Wisteria/Clearbrook drainage improvements project. 1) Improve flooding issues and aging/damaged infrastructure issues within the project boundary. 2) Improve water quality and habitat in the Hewlett's Creek watershed. 3) Obtain access through land and easement acquisition to the main stream and drainage system for drainage maintenance and protection of the aquatic resources. The City intends to achieve the above as described in this application and supporting documentation and plans. The following sections describe the current flooding and analysis and measures taken to avoid and minimize impacts, as well as the proposals to achieve the simultaneous goals of improving flood attenuation and providing improved water quality and habitat functions. The design approach for the project is to target improvements in areas with obvious historical alterations and fill while leaving the areas with the apparent highest functioning wetlands and stream un-impacted (except for debris or invasive species removal). Additionally, in areas that are proposed for impacts methods are proposed that will, in the long term, improve function and habitat. Other high-functioning areas such as the property at the corner of Shuney and ❑�❑ Kimley-Horn � antl Associates,Inc. Brittain will be preserved. This approach meets the City's goal of improving flood attenuation and improving water quality. The final design and construction of the project will occur in two stages. Stage 1 includes the project from the terminus just below Patricia Drive up to, but not including the culvert replacement at Dogwood Lane. Stage 2 is from Dogwood Lane to Verbenia Drive and includes improvements at Oak Bluff Lane where there are no jurisdictional areas. It is of note that the design plans for Stage 1 are provided at 75% and the design plan for Stage 2 are at 25%. 3.2 Flooding and Analysis Flooding within the project area has been well documented. The City has held two public meetings on April 28, 2009 and October 27, 2010 to present the project and gather input, and present 25% Plans and gather input, respectively. During these public meetings, citizens were asked to describe the flooding as it occurred in specific storm events. Major tropical systems were discussed as well as heavy thunderstorms. Wind tides and tides in combination with storm events were discussed as well. All of this information was gathered and used to calibrate the model as described below. Many citizens were able to provide photos of the actual flood events as well. In addition to flooding many citizens were concerned about preserving large trees and that the project be beneficial to the environment. The citizens contacted for these meetings are included in Table V. Hewlett's Creek is a tidally influenced creek whose entire watershed is located within the Wilmington city limits. The National Flood Insurance Program (NFIP) Digital Flood Insurance Rate Map (DFIRM) panel 3146J indicates that Hewlett's Creek special flood hazard areas were determined using a surge analysis. Special hazard areas associated with the Project area can be seen in Section 5.0, Figure 7 FEMA Floodzone Map. In order to analyze the Project area existing conditions and proposed improvements, both hydrologic and hydraulic models were created using the United States Army Corps of Engineers Hydraulic Engineering Center (USACE-HEC) programs HEC-HMS (Hydrologic Modeling System) and HEC-RAS (River Analysis System), respectively. The Project area is located in a low energy, sandy system confined by urban development which encroaches and constricts the active floodplain. These factors create hydraulic conditions that question the validity of several assumptions in both normal HEC-HMS and HEC-RAS modeling. An example of a site specific trivial assumption in HEC-HMS is the various routing methods that can be selected. The Kinematic Wave and Muskingum methods cannot account for the influence of backwater effects (tidal/surge or undersized culverts) or from significant velocity changes occurring at transitions from channel to overbank conveyance; both situations are anticipated to occur in the Project drainage system. To correct this problem, flow hydrographs will be taken from un-routed sub-drainage basins in the HEC-HMS model and inserted as lateral flow hydrographs in an unsteady-state HEC-RAS model. The unsteady-state HEC-RAS model will account for storage in the floodplain and energy losses in conveyance transitions due floodplain encroachments. To compensate for tidal influence, synthetic stage hydrographs were ❑�❑ Kimley-Horn � antl Associates,Inc. developed and input as downstream boundary conditions for both normal elevation tides and storm surges. The HEC-HMS model was applied the SCS hypothetical storm to generate flow hydrographs.The SCS hypothetical storm takes a rainfall depth uniformly distributed across a watershed during a 24-hour duration using a specified time distribution. The Project watershed was dissected into ten discrete sub-basins using road crossings as outfalls. Sub-basins were delineated based on field observations of stormwater structure connectivity, topographic data and stormwater structure GIS feature classes provided by the City. A map of the delineated sub-basins can be found in Section 6.0, Figure 7 Project Drainage Area Map. A detailed explanation of the development of the HEC HMS model is included in the Feasibility Study (November 2009). An unsteady-state HEC-Ras model was developed to assess the hydraulics of the Project. An Existing Conditions HEC-RAS model was created using HEC-GeoRAS to extract topographic data. To simulate tidal influence, the stream was extended downstream of the survey area to the confluence of Hewlett's Creek and the Intracoastal Waterway. The closest tidal gauge was Wrightsville Beach, NC NOAA Station 8658163 at Masonboro Inlet; station information from this gauge was used to develop the tidal hydrographs. Since the intent of this study was to determine peak flooding situations and not bridge scour, the storm surge was timed to peak at high tide. Due to the proximity of the Project to the Intracoastal Waterway, it was determined that surge analysis should be performed using the 50 year peak surge and 25 year storm. Any higher combination of both was found to be statistically improbable. A complete discussion of the development of the HEC-RAS model is included in the Feasibility Report (November 2009). After the first public meeting and gathering of information about historical storm events, several storms were targeted as calibration events. The historical storms used to calibrate the HEC-RAS model include: a tropical storm occurring on Aug 2008 and Hurricanes Fran, Floyd and Ophelia. These storms cover the breadth of design events from precipitation depth (25 and 100 year 24 hour recurrence interval), intensity, and storm surge as well as providing sufficient community supplied calibration points to gauge output. Meteorological data was downloaded from the NOAA National Data Center's website for each storm. Data downloaded from the NOAA National Data Center was listed in incremental inches per hour from Wilmington International Airport. Tide data was downloaded from Wrightsville Beach, NC NOAA Station 8658163 at Masonboro Inlet for Hurricane Ophelia and the 2008 tropical storm. Because the gauge was installed in 2004, tidal data for Hurricane Fran was taken from the Wilmington, NC NOAA Station 8658120 while a synthetic stage hydrograph was developed for Hurricane Floyd. The Hurricane Floyd hydrograph combined tide and surge functions using the methods described in section 3.1.2. Timing and peak surge parameters were estimated based on historic data received from NOAA stations 8661070 (Springmaid Pier, SC), 8658120 (Wilmington, NC), and 8656483 (Beaufort, NC). 3.3 Alternatives Analysis Based on City staff input, public input, agency coordination, previous drainage studies, and the site field assessment, several design approaches were evaluated. Approaches such as widening ❑�❑ Kimley-Horn � antl Associates,Inc. the entire stream throughout the Project area, for instance, were not evaluated because it is unlikely that this would meet the minimum criteria of avoidance and minimization of impacts. The design approaches were developed with the goals of addressing the flooding, improving water quality, and obtaining maintenance access. The concept approaches were modeled individually using HEC-RAS unsteady state. The results of each approach were compared to the water surface elevation results from the existing conditions HEC-RAS unsteady state model. A total of twenty-eight (28) design approaches were modeled as part of the Feasibility Study. These approaches are detailed in the Feasibility Report (November 2009) and summarized below. These approaches were evaluated (and modeled) in combination with the other approaches to seek the most expeditious design in regards to the goals of the Project (flood reduction, water quality improvement, and access). Cost and constructability were also considered in selection of the approaches. Also, it should be noted that the City requested that the culverts be designed with a goal of carrying the runoff from a 25 year, 24 hour storm at full capacity, as well as passing the runoff from a 100 year, 24 hour storm without overtopping the respective public road. This design goal was not achievable in every case based on site constraints. Approach A—Culvert Replacement Approach A is to replace all but one of the existing culverts. The largest culvert (72" RCP) within the Project corridor conveys the 10-year storm, which may have met City design standards in place at the time of construction. This approach was incorporated into the final design. Flood reductions could not be achieved without upsizing the culverts. The culverts inverts will be buried the appropriate 1 foot. Approach B—Flood Bv-aass Channel Approach B calls for the excavation of a flood by-pass channel to divert flood waters above the bankfull event through the large wooded area on Reach 6. The flood by-pass channel would function as an excavated floodplain, but minimize stream and wetland impacts along Reach 6. Construction of the flood by-pass channel should increase the floodplain storage through Reach 6. Approaches B, C, and BC were ultimately rejected because the amount of grading required and land acquisition costs. Aaaroach C—Inline Storaee Wetland Design Approach C proposes the construction of an approximately 4.4 acre inline flood storage wetland located within the large wooded area along Reach 6. The inline storage wetland would divert flood waters above the bankfull event into the wetland area helping to attenuate flooding from large storm events. Approaches B, C, and BC were ultimately rejected because the amount of grading required and land acquisition costs. Approach BC— Inline Stora�e Wetland with Flood Bv-aass Channel ❑�❑ Kimley-Horn � antl Associates,Inc. This design approach paired the flood by-pass channel from Approach B and the inline flood storage wetland from Approach C. These two flood storage devices were combined in order to consider the cumulative effects on flood attenuation from using these approaches together. Approaches B, C, and BC were ultimately rejected because the amount of grading required and land acquisition costs. Aaaroach D —Clearbrook Drive Stream Rehabilitation and Floodalain Swale Design Approach D uses a natural channel design to increase the stream channel capacity near Clearbrook Drive in combination with a floodplain swale running between the houses at 413 and 409 Clearbrook Drive. The swale will convey floodwaters, and provide water quality uplift for receiving stormwater flows. The natural channel design would include floodplain benching to increase channel conveyance. Approach D2 was selected because of the greater combined water quality, habitat and flood reduction provided. Approach D1 — Clearbrook Drive Stream Widenin�. Floodplain Swale, and Culvert Expansion Design Approach D1 adds to Approach D with the enlargement of the culvert replacement on Clearbrook Drive. Approach D1 considers increasing the capacity of the culvert replacement while including all of the design aspects of Approach D. Approach D2 was selected because of the greater combined water quality, habitat and flood reduction provided. Approach D2—Clearbrook Drive Natural Stream Widenin�and Culvert Expansion Approach D2 analyzes the hydrologic affects of the stream widening with the culvert expansion, but excludes the floodplain swale. This approach was analyzed to determine the effect that the floodplain swale has on flood elevations in the Project reach. This approach was selected in combination with 12, below, because of better water quality, habitat and flood reduction benefits it provided as compared to D1 or D. Approach E—Salt Marsh Upstream of Patricia Purpose: Approach E proposes the creation of a salt marsh, which will utilize a parcel owned by New Hanover County located near the Patricia Drive culvert. The county owned parcel is located directly adjacent to the Project stream and north-east of Patricia Drive culvert crossing. The salt marsh would function as floodplain storage area that could possibly provide mitigation and improve water quality. Approach E3 was selected over E because of its greater flood and water quality benefits. Approach E1—Salt Marsh Upstream of Patricia with Culvert Expansion Design Approach E1 includes the salt marsh described in Approach E and analyzes the affect of placing an additional culvert under Patricia Drive. Approach E1 will utilize the additional area the county owned parcel provides to construct a larger culvert crossing, and to add conveyance ❑�❑ Kimley-Horn � antl Associates,Inc. capacity to the culvert replacement described in Approach A. Approach E3 was selected over E1 because of its greater flood and water quality benefits. Approach E2—Culvert Expansion at Patricia Design Approach E2 uses the same culvert expansion as Approach E1 without the addition of the salt marsh in the county owned parcel north of Patricia Drive. This approach was used as an indicator of the flood reduction in Approach E2 based solely on increasing the culvert capacity under Patricia. Approach E3 was selected over E2 because of its greater flood and water quality benefits. Approach E3—Two Salt Marshes at Patricia with Culvert Expansion Design Approach E3 will locate two (2) salt marshes near the Patricia Drive culvert crossing, one upstream and one downstream of Patricia Drive, and hydraulically connect them placing a second culvert crossing under Patricia Drive. The salt marshes would increase floodplain storage in the Patricia Drive area and would create or restore habitat and improve water quality. This approach was incorporated into the final design. Approach F—Profile Adiustment Reach 7 and Reach 8 During the modeling of Approach A it became apparent that adjusting the existing stream profile along the upper portion of the Project stream using natural channel design techniques would reduce flooding. The existing stream profile for Reach 7 and Reach 8 (approximately from Ruxton Way to the top of the Project at Camelia Lane) includes culverts and the stream profile flowing upgrade in several locations. Approach F would correct the profile using natural channel design techniques (to limit the need for mitigation and improve water quality), and create a consistent sloping bankfull profile. The use of natural channel design would be to re-establish a bankfull cross-section, and proper riffle (ripple)-pool sequence. Excavation required for this approach would be approximately 1,500 cubic yards, and could lower the invert elevation of the stream as much as 1.59 feet in some areas. Approach M, below, was incorporated into the final design because of the additional flood reduction benefits. Aaaroach G—Removal of Wetland Mounds Approach G calls for the removal of the large side-cast berms within the existing wetlands on Reach 1. These mounds exist within the wetland located on the county owned parcel at 421 Sharon Drive. The large mounds appear to have been created during historical dredging activities along this reach, and contain some piles of debris and trash. Removing these mounds did not have a significant impact to reduce flooding but was incorporated into the design because of the benefits of removing spoil piles and rehabilitating the wetlands. ❑�❑ Kimley-Horn � antl Associates,Inc. Approach H —Impound Reach 6 for Flood Stora�e Approach H proposes adding a weir structure just upstream of the Weeping Willow crossing to impound and detain runoff in the floodplain at Reach 6. To increase storage capacity, this design approach also includes the flood by-pass swale and BMP discussed in approaches B and C, respectively. This was rejected due to additional stream impacts and potential upstream flooding. Aaaroach I —Clearbrook Proaertv Acauisition (2 aroaertiesl Approach I looks to add flood conveyance capacity to the area surrounding the Clearbrook Drive culvert crossing. Design Approach I includes acquiring of two parcels containing single family structures near the Clearbrook Drive crossing, adding a culvert to the two proposed in Approach A for a total of three (3) 10.0' x 2.0' RCB culverts, increasing channel capacity with natural channel design (as discussed in Approach D), and grading a large floodplain bench on the acquired parcels. This was not incorporated into the final design because demolishing the second residence was determined not to result in significant enough additional flood reduction benefits to justify taking the residence. Approach 11—Clearbrook Propertv Acquisition (4 propertiesl Design Approach 11 includes all of the design aspects of Approach I and proposes acquisition of two (2) additional single family houses for a total of four (4) parcels. The additional acquisition in Design Approach 11 proposes to re-establish floodplain benching where the existing stream floodplain is constricted. Both parcel owners have not indicated historical flooding, but the properties encroach on the active floodplain increasing channel velocity and reducing floodplain storage. Acquiring the two additional properties upstream of Clearbrook Drive would allow for a large floodplain to be excavated providing additional flood storage for the entire Clearbrook Drive area. This was not incorporated into the final design because demolishing the four residences was determined not to result in significant enough additional flood reduction benefits to justify taking them. Approach 12—Clearbrook Propertv Acquisition (1 propertvl Design Approach 12 has similar flood storage and conveyance to that of Approaches I and 11, but would reduce the parcels acquired from two (2) to one (1). Design Approach 12 reduces the acquisition of parcels at Clearbrook Drive to one (1) property. Additionally the proposed culverts will be reduced to include only the two (2) 10.0' x 2.0' RCB culverts described in Approach A. This approach was incorporated into the final design. Approach J —Off-line Wetland Design Approach J looks at detaining a large drainage area (Drainage Basin 6) along Reach 6, south of the Ruxton Way crossing. The detention in Approach J would utilize the same area and location as Approach BC, and would require rerouting the three stormwater ponds in the general area to the off-line wetland BMP. In addition to providing significant flood storage ❑�❑ Kimley-Horn � antl Associates,Inc. capacity, the off-line wetland BMP would provide water quality benefit for the sub-basin 6 area. Excavation associated with this approach would be comparable to Approach BC. This approach would require the purchase of a large, forested parcel, adding significant cost to the Project. Also, the effects on upstream areas were not analyzed.As such, it was rejected. Approach K—Stream Rehabilitation from Ruxton Drive to Do�wood Lane The goal of Approach K is to correct the stream channel profile from just above Ruxton Way to Dogwood Lane while re-establishing a more natural, connected floodplain bench between Ruxton Way and Weeping Willow Road for flood attenuation. The existing stream between Ruxton Way and Dogwood Lane includes stream Reaches 5, 6, and the lower section of Reach 7. These reaches are some of the more impacted reaches in the Project corridor, as a result of watershed urbanization. These reaches have been channelized resulting in varying profiles. This has been incorporated to the final design. Approach K1 — Stream Rehabilitation from Ruxton Drive to Do�wood Lane with Plover Court Modification Approach K1 is identical to Approach K with one modification at Plover Court. A portion of Plover Court will be removed along with the 1 story house located at 5523 Plover Court. Enough of Plover Court will remain to allow access to the remaining properties located on the court, and to provide adequate turn around capabilities for traffic. This option analyzes flood reduction options for the Plover Court area. This approach was rejected because the flood attenuation improvements were such that the model predicted it would no longer flood in the 100 year design storm event. Approach K2 — Stream Rehabilitation from Ruxton Drive to Do�wood Lane with Plover Court Propertv Acquisition Approach K2 is also a modification of Approach K. Approach K2 evaluates the option of removing the 1 story single-family home located on the right bank upstream of the Plover Court culvert crossing. Approach K2 further analyses hydraulic possibilities in the Plover Court area. Design Considerations and Assumptions: This approach proposes the acquisition of the above mentioned property, and the excavation of a large floodplain bench on the vacant parcel. The Project stream could also be relocated, as needed, to meander through the newly excavated floodplain. This approach was rejected because the flood attenuation improvements were such that the model predicted it would no longer flood in the 100 year design storm event. ❑�❑ Kimley-Horn � antl Associates,Inc. Approach K3 — Stream Rehabilitation from Ruxton Wav to Do�wood Lane with Extendin� Culvert at Plover Court Approach K3 is the third modification of Approach K to evaluate feasible options in the Plover Court area. This was rejected because of the additional stream impacts and cost. Approach K4—Stream Rehabilitation from Gardenia Lane to Do�wood Approach K4 extends the stream rehabilitation of Approach K upstream to include Reach 7 from Gardenia Lane to Ruxton Way. This approach was necessary to address the profile of Reach 7, and provide a more consistent stream slope to improve flow conveyance. This was incorporated to the final design. The accepted approach also call for the relocation of Plover Court resulting in a shorter piped section of stream than current exists. Approach L— Remove 48-inch RCP at Wisteria Lane Approach L calls for the removal of the existing 48-inch RCP culvert near the Wisteria Lane and 58t" Street intersection. Currently, the 48-inch culvert provides access to an existing stormwater facility for a nearby residential development. During the meeting with City staff on August 18t", 2009 it was determined that this existing access could be removed, if necessary, as required maintenance access for the facility can be gained from Gardenia Lane. According to the model conducted for this study, the existing culvert at this access point is undersized. This is further substantiated by the 72-inch culvert located approximately 260 feet downstream under Gardenia Lane. The City can save money by removing this culvert and not replacing it with a more appropriately sized culvert, as Approach A calls for. It was decided to leave a shorter section of 72" RCP culvert, day-lighting a portion of the stream. This will serve to maintain access to the adjacent stormwater pond for maintenance. Approach M —Channel Widenin�and Profile Adiustment Verbenia Lane to Gardenia Lane Purpose: Approach M is similar to Approach F; however the profile adjustments will be proposed starting from Gardenia Lane to Verbenia Lane, and will involve widening the channel to accommodate typical bankfull dimensions for a Rosgen "C" type channel. This approach was incorporated into the design because of the additional flood reduction benefits. Approach N —Uasize Drivewav Culverts to carrv 25-vear Storm Event The goal of Approach N is to analyze the feasibility of upsizing the existing driveway culverts of three (3) private residences along Dogwood Lane. Approach A considers upsizing the culverts associated with the major road crossings along the Project corridor; however, it did not address these three(3) driveway culverts. This approach will analyze the necessary size of the driveway culverts to convey the 25-year storm event, and the driveway elevation necessary to provide ❑�❑ Kimley-Horn � antl Associates,Inc. the minimum amount of cover on top of pipe. It was determined that this could not be achieved without exacerbating flooding in larger events such as the 100-year storm. Approach N1—Upsize Drivewav Culverts The goal of Approach N1 was to upsize the flow capacity of the driveway culverts analyzed in Approach N, but without raising the elevations of the existing driveways and thus the WSE of the 100-year storm. This would result in minimal new stream or wetland impacts. This approach was incorporated to the design. Approach O—Do�wood Lane Design approach K assessed creating retention basin by excavating uplands in the vacant wooded lot to the northwest of the Dogwood Lane culvert. The drainage contributing to this location includes a portion of impervious area from Oleander Drive. Preliminary modeling indicated that the discharge to this location was insufficient to significantly affect up or downstream flooding by detaining it. 3.4 Proposed Impacts The design approach avoids and minimizes impacts to the highest functioning jurisdictional features, focusing impacts on areas that have the most obvious signs of having been historically disturbed. Tables III-A, III-B, and III-C summarize the impacts to wetlands, streams and jurisdictional road side ditches (that are not modified natural channels). Tables III-A and III- B report the impacts as either temporary or permanent impacts to streams and wetlands. Table III-C is different in that it reports the only the impacts as shown on Sheet I-2 as either excavation of fill, and where in the impacts are proposed in relation to the Normal High Water (NHW), CAMA 30-foot Exclusion Zone, and the Area of Environmental Concern (AEC). There are no impacts proposed inside the NHW except for the placement of a silt curtain. There are also no impacts proposed to coastal wetlands. All of the permanent impacts to the stream and wetlands are associated with the culverts, except that some RPWs such as those parallel to Patricia Drive and Clearbrook Drive will be impacted to create salt marsh and potential wetland. These RPWs are not considered to be streams or modified natural stream channels, but are wet roadside ditches. These account for most of the permanent channel impacts (178 of the 283 feet), and should not require mitigation since they will be replaced with higher functioning natural systems. Almost all the temporary wetland impact areas will be replanted with appropriate, native forest or marsh vegetation. As such, it is not anticipated that mitigation will be required for these areas as well.The permanent wetland impacts are only 70 square feet. Proposed Impact Summary Permanent Channel (ft) Temporary Channel (ft) Permanent Wetland (ac) Temporary Wetland (ac) 283 4,107 0.0016 0.70 ❑�❑ Kimley-Horn � antl Associates,Inc. Utilities — The project will include the relocation of some utilities associated with the culvert replacements and the relocation of Plover Court. The impacts from the utilities will be temporary and only within the footprint of the impacts shown for the project. Stormwater - It has been determined that a State Stormwater Permit will not be required for this project based on the email from the Division of Water Quality to the City. This is because the project is not considered to be development by definition. See Appendix 7. FEMA Floodplain — A large portion of the project area is located in a Special Flood Hazard Area due to surge. The project should not have any negative impact on surge. See Figure 7. 3.5 Proposed Natural Resource Improvements and Protection The design approach avoids and minimizes impacts to jurisdictional features with the apparent highest functioning ecosystems. Additionally, the approach employs measures that will enhance or restore the natural functions of historically impacted areas where improvements are proposed. The proposed improvements are such that no mitigation is anticipated for the minor amount of temporary impacts. All of the channel work will be performed using natural channel design techniques that preserve, maintain, or restore a geomorphically appropriate low-flow channel. Additionally, habitat structures are proposed through the areas where channel improvements are provided. Impacted wetlands will be allowed to re-establish except for a small amount of impacts associated with the culverts. Near the terminus of the project, historic fill for two residential lots will be removed and returned to coastal marsh wetlands (based on the NRCS Soil Survey map — Figure 4B). The Appendices and Plan Sheet include details and supporting documentation for the design of these natural systems. A more detailed description of the natural system designs proposed for each reach are below. See Figures 5A, 5B, and 5C for the location of each reach. Spoil — Spoil to be removed from the site will only be disposed of in areas permitting by the Division of Land Quality. The contract will be required to notify and receive approval from the City for any and all disposal areas. In no event shall any of the spoil be placed in areas under jurisdiction by the USACE, DCM, or DWQ. See Figures 5A, 5B, and 5C as well as the Plan Sheets for the descriptions below. Reach 1: a) Convert the existing County parcel north of Patricia and residence south of Patricia into salt marsh. These systems would be connected by a dual box culvert under Patricia. This opportunity serves multiple purposes in that it could improve water quality, provide habitat, and attenuate flooding. The anticipated amount of salt marsh to be re-created is about 0.39 acres. b) Remove existing spoil piles within wetland/stream complex. Removal of the spoil piles should be considered wetland rehabilitation and would potentially increase the amount of wetlands in the project boundary. By far the main benefit would be to improve ❑�❑ Kimley-Horn � antl Associates,Inc. habitat and water quality. The modeling predicts that the removal of the piles would increase flood storage and conveyance, but only marginally relieve flooding. c) Provide stream enhancement from Patricia upstream to the point where the stream enters the forested area. This could greatly improve habitat and reduce maintenance by providing a better sediment transport regime to this over-widened system. Reach 2: a) Preserve the stream section in back of the undeveloped lots at 524 and 528 Shuney Street. This section of stream is complexed with a wetland system. It is forested and relatively unimpacted. Based on its relatively natural and stable condition, it could present an opportunity for onsite mitigation. Preserving the system would also preserve valuable habitat and protect water quality. b) Purchase or otherwise acquire the entire lot just downstream of the culvert under Shuney Street. The majority of this lot is wetland, and it will be preserved. Reach 3: a) Preserve the lot at the corner of Brittan and Shuney. The City has already secured this parcel. The parcel contains a section of stream complexed with a wetland. The area is forested and the stream is relatively intact with a pronounced riffle/ripple pool sequence. Preserving the system would preserve valuable habitat and protect water quality. Reach 4: a) Preserve the stream and wetland complex immediately upstream of Brittain Drive within the easement boundary. b) Preserve the section of stream from the driveway at 620 Dogwood Lane upstream to the bend at 520 Dogwood Lane. However, there is a considerable amount of privet which may be removed, especially near the culvert under pogwood Lane. Reach 5: a) Conduct stream rehabilitation of the stream channel between Dogwood Lane and Weeping Willow Road. This section of stream has been historically impacted and has unstable sections. Additionally, the pipe under Plover Court is not adequately sized to carry even small storms and is filled with sediment and debris. It is proposed that the Plover Court be slightly relocated and that a shorter pipe is provided to accommodate two driveways. A Priority II stream rehabilitation is proposed to restore natural functions to the stream and increase flood conveyance and storage capacity. Reach 6: a) Provide a flood storage/bypass flood plain at a lower elevation. The main purpose of this measure is to provide additional flood storage capacity. However, the stream which is very incised and channelized would be re-established using natural channel design techniques. This would provide better connection between the new floodplain and stream improving both water quality and habitat in the system. It could also result in the ❑�❑ Kimley-Horn � antl Associates,Inc. re-establishment of the impacted wetlands as well as the creation of wetland areas within the newly created floodplain. Reach 7: a) Adjust stream bed elevation using natural channel design techniques. This is needed to increase channel capacity and flood storage. Conducting the channel work using this method would improve habitat diversity. Reach 8: a) It is necessary to improve channel capacity in some of this section. This reach is likely the most degraded of the reaches both from and geomorphic and ecological point of view. As such, improving channel capacity and flood storage using natural channel design techniques should be considered an improvement from an ecological uplift perspective. 4.0 Conclusion and Proposed Alternative Selection The proposed project seeks to improve flood attenuation while providing an overall improvement in water quality and habitat. Flooding has been well documented along the stream in the project area. Much of the stream and wetlands have been historically altered or filled within the project area. Although the project does not propose to completely restore these areas, it does propose to improve them by re-creating wetlands and salt marsh, using natural channel design techniques for sections of stream that were historically altered, removing historic fill in some locations, and by re-establishing a connection between the stream and its floodplain. Areas that are relatively un-impacted will be preserved. As such, the proposed design should be considered an acceptable alternative that meets the City's goals. ❑�❑ Kimley-Horn � antl Associates,Inc. 5.0 Figures :� � \ �a r �! � 1$2 1 Atlantic Ocean � 0 0� a�h ��rb 4- s� �na r � � .° � �s t�r�d <n Q< �� � �� 'AOii,;� o� Uw 'Ao.J,� ,�� Q� Q�o a`° ��� C�llie C� ac � m o � �o o� � Qo�' �dy � pi Carolyn Dr p � '' o .� �� �` � c°' O� r�� �¢, �c h'i//wood St � yar�s et �� �`o c�o� � n m �� V �.

We get water on the road during bad rain storms and in my ditch running parallel to Ruxton Way. The Ruxton Way culvert has overflowed in the past during extreine weather. The water in the Tributary is dry most of the year. We don't have issues behind my house on the tributary. The corner of Ruxton and Azalea gets over flow water fiom the East. We are concerned that the new development East of us will cause more stress to the drainage as each new neighborhood has. Why don't you do soinething that may actually raise my property value. Make Hewletts Creek accessible using the tributary for kayaks and motor less water craft. I imagine you could build a :. sinall craft water way that encompasses Wilmington if some thought was put into it. Not a stone canal, those never turn out good. RNB.

John F Williams To todd.stjohn@kimley-horn.com, '� '�t <'ohn.f.williams mwv.com> 1 @ dave.mayes@wilmingtonnc.gov 04/28/2009 09:55 AM �� pat.higgins@wilmingtonnc.gov bcc Subject Wisteria/Clearbrook Drainage Improvement Project To Whom it May Concern, First, thank you for the effort you are putting toward improving this drainage system. You can see from the attached map, that I live on the property where this drainage system crosses Ruxton Avenue. This drainage system back ups and floods our yard, and sometimes covers the road, in very heavy rains. During tropical storms, it floods nearby yards (and some crawlspaces)and makes the road impassable. We have also noticed that over the past year, water is always in the drainage system. Prior to that, it would drain out within a few days of the last rain. Now the water doesn't seem to flow during the rain, and never fully drains out. It would seem that there is something happening downstream to obstruct the flow,:. and the obstruction has grown over the past year. In addition to the flooding issues it causes, it also harbors mosquito growth in the area. Thanks for evaluating these issues. John Williams 5613 Lands End Ct.

Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina 1 Project Purpose The Wisteria/Clearbrook Drainage Improvements Project (Project) is proposed by the City of Wilmington for the purpose of improving drainage, minimizing flooding issues, improving water quality flowing in Hewletts Creek. In addition, the project will establish access throughout the project so that the City can have maintenance responsibility for the drainage. It is anticipated that these improvements will be achieved through the use of natural channel design techniques, wetland restoration, offline stormwater BMPs, stormwater detention practices, and culvert replacement. The purpose of this report is to provide a brief summary of the environmental review that was conducted for the project, and to identify the environmental constraints. 2 Project Setting The Project is located in Wilmington, New Hanover County, North Carolina. The Project area is located south of Oleander Drive (U.S. Highway 76) and west of Greenville Loop Road, as shown in Figure 1. The Project occurs entirely within a residential area that includes recently constructed upscale homes, mid-century single family homes, and mobile homes. The majority of open space within the project area is forested. The Project drainage area includes commercial areas along Oleander Drive, residential neighborhoods of varying density, and an electrical substation surrounded by residential areas. The tributary is located within a topographic depression that appears on the USGS 1:24,000 scale Wrightsville Beach, North Carolina Quadrangle Map (USGS, 1970), which is included as Figure 2. It is apparent from the condition of the tributary that much of the stream has been substantially modified in the past, either through dredging or relocation. Almost the entire drainage appears to be significantly altered from reference condition with regard to pattern, dimension, and profile. It is likely that this manipulation has also affected the extent and function of wetlands adjacent to the stream system. The exception to this is a several hundred foot reach of stream that occurs between Brittain Drive and Shuney Street, an approximately 200 foot section of stream parallel to Clearbrook Drive, and an approximately 200 foot section beginning just above a driveway crossing parallel to Dogwood Lane, where the stream and riparian buffers have recovered or remain relatively intact. Appendix A is a log of representative photographs of the stream system. The Project occurs along an unnamed tributary of Hewletts Creek identified by the North Carolina Division of Water Quality (NCDWQ) as Stream Index#18-87-26. Hewletts Creek is located in the Cape Fear River Basin, Hydrologic Unit Code 03030001. Downstream of the project area, Hewletts Creek is classified as SA (Market Shellfishing, Salt Water), HQW (High Quality Waters). Hewletts Creek is included on the 2008 Draft 303(d) list as an impaired water due to excessive levels of Fecal Coliform. The watershed that drains to the project area is approximately 1000 acres in size, with land uses including commercial/industrial (±10%), open space/forested (±10%), and medium density residential (±80%). Approximately the lower third of the project area is located within the 100-year floodplain, as shown on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM). The floodplain was also modeled by the City, which extended the limits of the 100-year floodplain to include most of the project area. Figure 3 shows the different drainage basins for the project area, the soil units as mapped in the New Hanover County Soil Survey (USDA, 1977), and the 100-year floodplain limit (to the limit of either the FEMA map or the modeled floodplain, whichever is greater). 1 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina 3 Aquatic Resources Wetlands, streams and open waters are under the regulatory jurisdiction of the U.S. Army Corps of Engineers (USACE) pursuant to Section 404 of the Clean Water Act, which regulates the disposal of dredged or fill material into "waters of the United States." The term "waters of the United States" includes both surface waters (e.g., streams, ponds, lakes, etc.) and wetlands. Also, in North Carolina, the NCDWQ has regulatory authority over wetlands, streams and open waters through Section 401 of the Clean Water Act. The USACE is the lead agency for certifying the extent of jurisdictional "waters of the United States" within a project area. The locations of streams and wetlands identified in this report were reviewed by the USACE and NCDWQ on December 9, 2008. The approved jurisdictional determination by the USACE is provided in Appendix B. 3.1 Wetlands The identification of wetlands was performed using methodologies outlined in the 1987 Corps of Engineers Wetlands Delineation Manual, which is the current methodology approved by the USACE for conducting jurisdictional determinations. For an area to be considered a wetland, it must satisfy three specific criteria, including the prevalence of hydrophytic vegetation, presence of hydric soils, and positive indicators of wetlands hydrology. The delineation, which was conducted from September 2—4, 2008, included a review of these criteria within potential wetlands located within the project area. Wetland data forms were prepared for each identified wetland to document the findings, and have been included as Appendix B. Wetland boundaries were demarcated with flagging at a spacing of 50 to 100 feet and located with global positioning system (GPS) equipment for planning purposes. These areas were later field surveyed for the preparation of wetland maps. Figure 4 shows the location of wetland areas that were identified during the field reconnaissance. An on-site USACE review of these areas was conducted on December 9, 2008. In some cases, open waters, streams, or wetlands that are isolated from other waters (i.e., not adjacent and lacking a surface hydrologic connection) may not be subject to Section 404 or 401 of the Clean Water Act. In these cases, NCDWQ independently regulates isolated areas as "waters of the State" under separate state regulations. One small isolated wetland, identified in the figures as Wetland J, was identified within the project area. The USACE has confirmed that this area is isolated and therefore subject to regulation by NCDWQ. 3.2 Streams Stream channels located within the project area were assessed to determine if they are subject to federal and/or state jurisdiction and to determine the flow regime. The USACE classifies water conveyances (including streams) as either Relatively Permanent Waters (RPWs), which have perennial or intermittent seasonal flow (i.e., 20 or more flow events per year), or Non-relatively Permanent Waters (Non-RPWs) which are ephemeral and have less than seasonal flow. All observed jurisdictional conveyances within the project area were assessed to be RPWs. The NCDWQ uses a guidance document titled Identi�cation Methods for the Origins of Intermittent and Perennial Streams (Version 3.1, Feb. 2005) to classify stream channels as ephemeral, intermittent, or perennial. The stream channels within the project area were assessed using this methodology and generally determined to have perennial flow. Copies of the NCDWQ Stream Identification Forms area attached as Appendix C. 2 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina 3.3 Reach Descriptions The results of the delineation are discussed below, addressed by project reach, starting from the lower end of the project and moving upstream. Figures 4.0 through 4.6 show the different reaches and wetlands along each reach. 3.3.1 Reach 1 The stream reach at the southern end of the project begins at Patricia Drive and extends upstream to Clearbrook Drive. A substantial portion of this reach appears tidally influenced, even if only during high lunar tides, however it does not appear that tidal action extends upstream of Clearbrook Drive. As shown in Photo 1, hydrology is also affected by the small culvert under Patricia Drive. The stream has been channelized throughout, with large spoil piles along the stream edge, as shown in Photo 2. The stream also appears to have several areas of bank instability, possibly due to the extensive dredging that has occurred in this area. This reach of stream received a score of 36.5 using the NC Stream Identification Methodology. The wetlands along this reach range from permanently inundated to semi- permanently saturated, and are forested with mature trees, including bald cypress (Taxodium distichum), swamp blackgum (Nyssa sylvatica), and red maple (Acer rubrum). Several invasive species are present in this area, including Chinese privet (Ligustrum sinense) and Chinese wisteria (Wisteria sinensis), that are affecting the integrity and diversity of the understory and canopy vegetation. It also appears that the extent of the wetland in this area was greater prior to development, and that fill has been placed to allow for residential construction, particularly along the eastern side of the stream. Soils are identified in the survey as Ur (Urban Land), meaning it was assumed to have been impacted by development, though they are highly saturated, and appear to be the wettest soils along the project corridor. The wetlands adjacent to this reach are shown on Figure 4.1. 3.3.2 Reach 2 The stream reach from Clearbrook Drive to Shuney Street appears to have been partially straightened or dredged, most notably immediately upstream of Clearbrook Drive, where the stream flows in a narrow ditch between houses. Just above the ditched portion at Clearbrook Drive there is a short reach of relatively intact or recovered stream surrounded by wetlands. It is evident that flooding in this section of the project is a regular event, and several of the surrounding residences are raised on pilings. The stream buffer has also been reduced in this reach by clearing that has occurred to extend yards, as shown in Photo 3. This reach of stream received a score of 48 using the NC Stream Identification Methodology. The wetlands within this reach follow along both sides of the steam, and in some areas extend several hundred feet from the stream. The wetlands have been impacted by development on both sides of the system. There appears to be historical fill in some areas, and other areas where the wetlands were cleared and planted in grass. Soils are identified in the survey as Urban Land (Ur) and Johnston Soils (JO), which are considered very poorly drained soils formed along the floodplains of major streams. The wetlands adjacent to this reach are shown on Figure 4.2. 3.3.3 Reach 3 The stream reach from Shuney Street to Brittain Drive was evaluated as the highest quality of any section within the project corridor. Only limited development exists along this reach, just upstream of Shuney Street. The stream appears to have close to reference condition pattern, dimension and profile 3 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina in this area, and the riparian buffer remains intact, as shown in Photo 4. This reach of stream received a score of 49.5 using the NC Stream Identification Methodology. Wetlands are located adjacent to both sides of the stream, with a seep extending upslope to the east of the stream channel. Some fill is evident within the floodplain that may have reduced the historical extent of the wetlands. Soils are identified in the survey as Johnston Soils. The wetlands adjacent to this reach are shown on Figure 4.2. 3.3.4 Reach 4 The stream reach from Britain Drive to Dogwood Lane has been straightened in sections and manipulated by residential development. There are several spots along the stream where structures have been constructed within or immediately abutting the stream bank, including bulkheads, bridges, and culverts. As a result, the natural hydrology of this section of stream has been severely altered, resulting in more extensive flooding in several areas. Yard maintenance has also led to the removal of the riparian buffer down to the stream bank along several stretches. This reach of stream received a score of 36 using the NC Stream Identification Methodology. The wetlands adjacent to this reach are the most extensive wetlands within the project area, but they are also highly impacted by development. Several yards extend into wetland areas, and three culverted driveways cross the wetland, shown in Photo 5, substantially altering their hydrology. Just above the series of driveway crossings, there is a section of relatively intact or recovered stream. There is a separate drainage that enters this system from the north, which contributes a sizable hydrologic input into the system. A large wetland system extends up this system and off the project area. Soils are identified in the survey as Johnston Soils. The wetlands adjacent to this reach are shown on Figure 4.3 and 4.4. 3.3.5 Reach 5 This small reach begins at Dogwood Lane and extends upstream to Weeping Willow Road. The stream throughout this area has been straightened and confined to a ditch. Houses have been built close to both sides of the stream, with little floodplain or riparian buffer present, as shown in Photo 6. The stream also passes through a culvert under the end of a cul-de-sac, which acts as an additional obstruction to the hydrology of the system. This reach of stream received a score of 32.5 using the NC Stream Identification Methodology. Due to the extent of development, only a small wetland pocket remains in a low spot immediately adjacent to the stream. Soils are identified in the survey as Torhunta loamy fine sand (To), which are very poorly drained soils that form in marine and fluvial sediments in slight depressional areas. The wetlands adjacent to this reach are shown on Figure 4.5. 3.3.6 Reach 6 The stream reach from Weeping Willow Road, upstream to Ruxton Way was historically relocated into a in a deep, excavated ditch. The riparian buffer is generally still intact along this stretch of stream, but spoil piles along the sides of the ditch and the entrenched nature of the stream limit the ability of the stream to interact with the buffer and floodplain. A typical view of this reach is shown in Photo 7. This reach of stream received a score of 27.5 using the NC Stream Identification Methodology. Even though this reach was rated as an intermittent stream, the channel appears to be perennial, and the low score was attributed to the lack of natural geomorphic features caused by the ditching. There are two wetland areas adjacent to the stream that are forested with a mix of mature hardwoods and pine, but their extent appears to be reduced due to the drainage effect of the ditch that conveys the stream. The 4 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina condition of the steam in this area also limits overbank events that would normally provide additional hydrologic input to these areas. Soils are identified in the survey as Torhunta loamy fine sand, and Seagate fine sand (Se), which are classified as somewhat poorly drained soils that formed in marine and fluvial sediments in nearly level flatwood areas. The project area along this reach extends into a forested area located to the south of the stream. This area contains a depression with soils classified as Leon sand (Le), which are poorly drained, nearly level soils on the rims of depressions and in flats. This small area was reviewed by the USACE and determined to be an isolated depressional wetland with no hydrological or ecological connection to downstream jurisdictional areas. This area is surrounded by an upland ridge, which is shown in Photo 8. The wetlands adjacent to Reach 6 are shown on Figure 4.6. 3.3.7 Reach 7 The stream reach between Ruxton Way and Gardenia Lane is located within a large ditch with yards backing up to the stream on both sides. The ditch appears to have been more recently excavated, and is large enough to carry expected storm flows. As a result, it is not expected that overbank flooding occurs along this reach, with the possible exception of immediately upstream of Ruxton Way, which may act as a hydrologic barrier. A view of this reach is shown in Photo 9. This reach of stream received a score of 33 using the NC Stream Identification Methodology. Soils are identified in the survey as Seagate fine sand and Leon sand. No wetlands were identified within this reach. 3.3.8 Reach 8 The stream reach beginning at Gardenia Lane and extending to Verbenia Drive is the terminus of the project area. This reach of stream is also located in a recently excavated ditch. Houses are located behind a narrow vegetated buffer on the east side of the ditch, and South 58th Street abuts the ditch to the west. The ditch is large and appears to provide adequate capacity to carry expected flows. Water is standing in the bottom of much of the lower sections of the reach, with aquatic vegetation occurring in areas. A typical view of this reach is shown in Photo 10. The reach received a score of 30.5 using the NC Stream Identification Methodology. Soils are identified as Leon sand and Kureb sand, 1 to 8 percent slopes (Kr) in the survey, which are excessively drained sloping soils formed on ridges. No wetlands were identified within this reach. 4 Coastal Resources Within North Carolina's 20 coastal counties, there are additional regulations in place that govern development within coastal resource areas. These regulations are administered by the North Carolina Division of Coastal Management (NCDCM), which carries out the state's Coastal Area Management Act (CAMA), the Dredge and Fill Law, and the federal Coastal Zone Management Act. NCDCM jurisdiction extends to portions of the coastal system known as Areas of Environmental Concern (AEC). AECs include all lands, including uplands, within 75 feet of the normal high water line along estuarine waters, and all lands within 30 feet of the normal high water line along inland fishing waters. AECs also include any coastal wetlands that extend beyond these limits. Coastal wetlands are defined by CAMA as any marsh subject to regular or occasional flooding by wind or lunar tides, which also supports one or more particular wetland plants. 5 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina The project site was reviewed by NCDCM on December 9, 2008. During the review, NCDCM noted the presence of CAMA wetland plant species extending up to the crossing of Clearbrook Drive. As a result, it is expected that the AEC will extend 75 feet from the downstream end of the culvert under Clearbrook Drive. Final NCDCM verification of the limit of the AEC is still pending. 5 Cultural Resources Section 106 of the National Historic Preservation Act requires that, prior to conducting any activity, federal agencies take into account the potential effect that their action may have on properties that are listed or elegible for listing on the National Register of Historic Places. As a result, the USACE must coordinate with the North Carolina State Historic Preservation Officer (SHPO) and the Office of State Archaeology (OSA) for any 404 permit applications that may affect listed or eligible historic or archeological resources. Formal consultation with the above agencies was not completed as part of this project, and no written correspondence has been obtained; however, a review of available databases at the SHPO and OSA was conducted on September 25, 2008 as part of the evaluation of the project area. The review did not identify any cultural or historic resources within the project area. There are several listed structures within the vicinity of the project area; however no structures occur within 0.25 miles of the project area. Additionally, there are seven listed archeological sites within 0.25 miles of the project area. None of these sites has been assessed and all are recommended for testing. Based on preliminary mapping, it is not possible to determine whether these sites would be disturbed by construction within the project corridor. As a result, further coordination with the SHPO is pending. 6 Threatened and Endangered Species The Endangered Species Act (ESA) of 1973 (16 U.S.C. 1531-1943) mandates that federal agencies ensure that any actions authorized, funded, or carried out by that agency do not jeopardize the "continued existence" of listed species or result in the destruction or adverse modification of critical habitat (16 U.S.C. 1536). The U.S. Fish and Wildlife Service (USFWS) is the federal agency that is responsible for ensuring that the provisions of the Endangered Species Act are met. Additionally, North Carolina laws grant limited protection to rare plants and animals that are endemic to the state or whose populations are in severe decline. Typically, protected species are only an issue on a project if federal/state funding is utilized for a project or if a federal/state permit is required for a project. Because this project may require a federal 404 permit from the USACE and state 401 Water Quality certification from DWQ for stream and/or wetland disturbances, the protected species issue is relevant. Formal consultation with USFWS and the N.C. Natural Heritage Program (NCNHP) was not completed as part of this project, and no written correspondence has been obtained. Information concerning the occurrence of federal and state protected species for New Hanover County was gathered from the USFWS list of endangered species, threatened species, federal species of concern, and candidate species for New Hanover County, North Carolina, and from the NCNHP database of protected species and unique habitats. These lists are included as Appendix D. The USFWS database, updated January 31, 2008, lists 9 species that receive federal protection under Section 7 of the ESA. Additionally, the review of the NCNHP identified three federally endangered or threatened species as potentially occurring within 2 miles of the project area, including the American alligator (Alligator mississippiensis), West Indian manatee (Trichechus manatus), and the red-cockaded woodpecker (Picoides borealis). Generally, specific concerns regarding impacts to threatened or endangered species are addressed during the permitting phase of the project, and it is therefore likely that additional coordination will have 6 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina to be conducted with the USFWS regarding potential impacts to these species or their habitats prior to the issuance of federal permits required for construction of the project. 7 Permitting 7.1 U.S. Army Corps of Engineers A permit must be obtained from the USACE, who authorizes work under Section 10 of the Rivers and Harbors Act, which is required for dredging, filling, and other work in navigable waters, and Section 404 of the Clean Water Act, which is required for discharges of dredged or fill material into waters of the U.S. The two basic types of permits issued by USACE are General Permits and Individual Permits. General Permits, also called Nationwide or Regional Permits, are required for specific activities where environmental impacts are minimal. These permits have a typical processing time of 45 days. Individual Permits are required for impacts that cannot be covered by a General Permit. Individual Permits require the issuance of a public notice and the preparation of an Environmental Assessment. Typical processing times for Individual Permits range from six months to over a year. 7.2 N.C. Division of Water Quality A water quality certification must be obtained from the NCDWQ, who issues certifications under Section 401 of the Clean Water Act as well as a host of other state water quality regulations, including isolated wetland rules and stream buffer rules. This certification is processed concurrently with the USACE permit, and typically takes 30 to 60 days to process. 7.3 N.C. Division of Coastal Management NCDCM is responsible for issuing CAMA permits, which are required for any development activity taking place within an AEC. All permits require that an on-site pre-application meeting is conducted with NCDCM, and that adjacent property owners are notified of the proposed project prior to submittal of the application to the NCDCM. Depending on the project, there are three types of CAMA permits that can be issued: Major Permits, General Permits, and Minor Permits. General Permits are required for activities that have little or no impact to the environment. They are issued during the on-site pre-application meeting. Minor Permits are required for single-family homes and other development projects with limited environmental impacts. These permits require submittal of an application to NCDCM, with a typical processing period of 25 days. Major Permits are required for activities that cannot be authorized by Minor or General Permits. They require submittal of an application form to NCDCM, and have a typical processing time of 75 to 150 days. The application is reviewed by 10 state and 4 federal agencies. During a Major Permit process, NCDCM coordinates the review and obtains necessary authorizations/permits from several other agencies as part of the Major Permit process, including a Dredge and Fill permit required by the N.C. Dredge and Fill Act, Fill Easements required by the N.C. Department of Administration, Water Quality Certifications required by the N.C. Division of Water Quality, and permits required by the U.S. Army Corps of Engineers. � ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina 8 Summary In summary, the project area occurs within an urbanized watershed that has been highly manipulated and contains a high level of impervious surface. The area supports jurisdictional streams and wetlands, including isolated wetlands, which are regulated by both State and Federal laws. The majority of these systems have been degraded by direct manipulation (channelization, fill, etc.) and by changes to the watershed resulting in increased stormwater runoff, along with higher levels of sediment, nutrients, and other pollutants. There are a few sections of stream and wetland that remain in relatively high quality. These sections occur in areas that still have an intact riparian buffer and appear to be less affected by recent disturbances. There do not appear to be significant issues associated with either cultural resources or endangered species. Several environmental permits will be required prior to any manipulation of streams or wetlands associated with the project. Initial coordination with the permitting agencies has been conducted; however, specific permitting requirements cannot be determined until project plans and associated impact amounts have been generated. g ��� Kimley-Hom � and Associates, Inc.

A taxon "in danger of extinction throughout all or a significant portion of its range." T =threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range." C = candidate. A taxon under consideration for official listing for which there is sufficient information to support listing. (Formerly "C1" candidate species.) BGPA=Bald and Golden Eagle Protection Act. See below. FSC=federal species of concern. A species under consideration for listing, for which there is insufficient information to support listing at this time. These species may or may not be listed in the future, and many of these species were formerly recognized as "C2" candidate species. T(S/A) =threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation. See below. EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation purposes, and as species proposed for listing on private land. P =proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively. Bald and Golden Ea�le Protection Act (BGPA� In the July 9, 2007 Federal Register(7237346-37372), the bald eagle was declared recovered, and removed (de-listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, 12/O 1/2008 the Bald and Golden Eagle Protection Act(Eagle Act) (16 U.S.C. 668-668d)becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of"take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit http://www.fws.gov/migrator�birds/baldeagle.htm Threatened due to similarity of a�pearance(T(S/A�: In the November 4, 1997 Federal Register(55822-55825), the northern population of the bog turtle (from New York south to Maryland)was listed as T (threatened), and the southern population (from Virginia south to Georgia)was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of the bog turtle as a Federal species of concern due to habitat loss. Definitions of Record Status: Current- the species has been observed in the county within the last 50 years. Historic -the species was last observed in the county more than 50 years ago. Obscure -the date and/or location of observation is uncertain. Incidental/migrant-the species was observed outside of its normal range or habitat. Probable/potential -the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties), the presence of potentially suitable habitat, or both. 12/O 1/2008 NC NHP County Element Search Results New Search Returned Elements: 62 using: NEW HANOVER LISTED [Invertebrate Animal 7] [Vascular Plant 23] [Vertebrate Animal 32] Major Grou� Scientific Name Common Name State Federal State Global County- Map_ Status Status Rank Rank Status Habitat Invertebrate Anodonta couperiana Barrel Floater E None SH G4 New Hanover Link Animal -Historical Invertebrate Atrytone arogos arogos Arogos Skipper SR FSC S1 G3T1 T2 New Hanover Link Animal -Obscure Invertebrate Atrytonopsis loammi Loammi Skipper SR FSC SH G1 New Hanover Link Animal -Obscure Invertebrate Helisoma eucosmium Greenfield Rams-horn E FSC S1 G1Q New Hanover Link Animal -Historical Invertebrate p�anorbella magnifica Magnificent Rams-horn E FSC S1 G1 New Hanover Link Animal -Historical Invertebrate problema bulenta Rare Skipper SR FSC S1 G2G3 New Hanover Link Animal -Current Invertebrate Triodopsis soelneri Cape Fear Threetooth T FSC S2 G2 New Hanover Link Animal -Current Vascular Plant Amaranthus pumilus Seabeach Amaranth T T S2 G2 New Hanover Link -Current Vascular Plant Amorpha georgiana var. confusa Savanna Indigo-bush T FSC S3 G3T3 New Hanover Link -Historical Vascular Plant Astragalus michauxii Sandhills Milk-vetch T FSC S3 G3 New Hanover Link -Historical Vascular Plant Crocanthemum nashii Florida Scrub Frostweed E None S1 G3?

Search performed on Monday, 22 September 2008 @ 14:37:21 EDST Explanation of Codes EXPLANATION OF CODES FOR COUNTY AND QUAD STATUS LISTS The county and quadrangle status lists provided by the NC Natural Heritage Program tally the elements of natural diversity(rare plants and animals, rare and exemplary natural communities, and special animal habitats)known to occur in all North Carolina counties and USGS 7.5-minute quadrangles. The information on which these lists is based comes from a variety of sources, including field surveys,museums,herbaria, scientific literature, and personal communications. These lists are dynamic,with new records continually being added and old records being revised as new information is received. As a result, a list cannot be considered a definitive record of the elements of natural diversity present in a given county or quad and should not be used as a substitute for field surveys.When this information is used in any document,we request that the date this list was compiled be given and that the NC Natural Heritage Program be credited. STATESTATUS CODE STATUS CODE STATUS �E Endangered SR Significantly Rare 0 Threatened EX Extirpated SC Special Concern P_ Proposed (used only as a qualif�ier of the ranks above) 0 Candidate NOTE: the definitions of state statuses of plants and animals differ. Below are summaries of the statuses for each group. Plant statuses are determined by the Plant Conservation Program (NC Department of Agriculture) and the Natural Heritage Program (NC Department of Environment and Natural Resources). Endangered, Threatened, and Special Concern species are protected by state law (Plant Protection and Conservation Act, 1979). Candidate and Significantly Rare designations indicate rarity and the need for population monitoring and conservation action.Note that plants can have a double status, e.g., E-SC, indicates that while the plant is endangered, it is collected or sold under regulation. CODE STATUS DEFINITION E Endangered "Any species or higher taxon of plant whose continued existence as a viable component of the State's flora is determined to be in jeopardy" (GS 19B 106: 202.12). (Endangered species may not be removed from the wild except when a permit is obtained for research,propagation, or rescue which will enhance the survival of the species.) T Threatened "Any resident species of plant which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range" (GS 19B 106:202.12). (Regulations are the same as for Endangered species.) SC Special "Any species of plant in North Carolina which requires monitoring but which may be collected Concern and sold under regulations adopted under the provisions of[the Plant Protection and Conservation Act]" (GS 19B 106:202.12). (Special Concern species which are not also listed as Endangered or Threatened may be collected from the wild and sold under specific regulations. Propagated material only of Special Concern species which are also listed as Endangered or Threatened may be traded or sold under specific regulations.) C Candidate Species which are very rare in North Carolina,generally with 1-20 populations in the state, generally substantially reduced in numbers by habitat destruction (and sometimes also by direct exploitation or disease). These species are also either rare throughout their ranges (fewer than 100 populations total) or disjunct in North Carolina from a main range in a different part of the country or world. Also included are species which may have 20-50 populations in North Carolina,but fewer than 50 populations rangewide. These are species which have the preponderance of their distribution in North Carolina and whose fate depends largely on their conservation here. Also included are many species known to have once occurred in North Carolina but with no known extant occurrences in the state (historical or extirpated species); if these species are relocated in the state,they are likely to be listed as Endangered or Threatened. If present land use trends continue, candidate species are likely to merit listing as Endangered or Threatened. �� 12/O 1/2008 SR Significantly Species which are very rare in North Carolina,generally with 1-20 populations in the state, Rare generally substantially reduced in numbers by habitat destruction (and sometimes also by direct exploitation or disease). These species are generally more common somewhere else in their ranges, occurring in North Carolina peripherally to their main ranges,mostly in habitats which are unusual in North Carolina. Also included are some species with 20-100 populations in North Carolina, ifthey also have only 50-100 populations rangewide and are declining. -L Limited The range of the species is limited to North Carolina and adjacent states (endemic or near endemic). These are species which may have 20-50 populations in North Carolina,but fewer than 50 populations rangewide. The preponderance of their distribution is in North Carolina and their fate depends largely on conservation here. Also included are some species with 20-100 populations in North Carolina, if they also have only 50-100 populations rangewide and declining. -�T Throughout These species are rare throughout their ranges (fewer than 100 populations total) -�D Disjunct The species is disjunct to NC from a main range in a different part of the country or world. -P Peripheral The species is at the periphery of its range in NC. These species are generally more common somewhere else in their ranges, occurring in North Carolina peripherally to their main ranges, mostly in habitats which are unusual in North Carolina. �Other The range of the species is sporadic or cannot be described by the other Significantly Rare categories �Proposed A species which has been formally proposed for listing as Endangered, Threatened, or Special Concern,but has not yet completed the legally mandated listing process. Animal statuses are determined by the Wildlife Resources Commission and the Natural Heritage Program. Endangered, Threatened, and Special Concern species of mammals,birds, reptiles, amphibians, freshwater fishes, and freshwater and terrestrial mollusks have legal protection status in North Carolina(Wildlife Resources Commission). The Significantly Rare designation indicates rarity and the need for population monitoring and conservation action. CODE STATUS DEFINITION E Endangered "Any native or once-native species of wild animal whose continued existence as a viable component of the State's fauna is determined by the Wildlife Resources Commission to be in �eopardy or any species of wild animal determined to be an'endangered species'pursuant to the Endangered Species Act." (Article 25 of Chapter 113 ofthe General Statutes; 1987). T Threatened "Any native or once-native species of wild animal which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range, or one that is designated as a threatened species pursuant to the Endangered Species Act." (Article 25 of Chapter 113 of the General Statutes; 1987). SC Special "Any species of wild animal native or once-native to North Carolina which is determined by the Concern Wildlife Resources Commission to require monitoring but which may be taken under regulations adopted under the provisions of this Article." (Article 25 of Chapter 113 of the General Statutes; 1987). SR Significantly Any species which has not been listed by the N.C.Wildlife Resources Commission as an Rare Endangered, Threatened, or Special Concern species,but which exists in the state in small numbers and has been determined by the N.C.Natural Heritage Program to need monitoring. (This is a N.C.Natural Heritage Program designation.) Significantly Rare species include "peripheral" species,whereby North Carolina lies at the periphery of the species' range (such as Hermit Thrush). The designation also includes marine and estuarine fishes identified as "Vulnerable" by the N.C. State Museum of Biological Sciences (Ross et al., 1988, Endangered, Threatened, and Rare Fauna of North Carolina. Part IL A Reevaluation of the Marine and Estuarine Fishes). EX Extirpated A species which is no longer believed to occur in the state. P_ Proposed Species has been proposed by a Scientific Council as a status (Endangered, Threatened, Special Concern,Watch List, or for De-listing)that is different from the current status,but the status has not yet been adopted by the Wildlife Resources Commission and by the General Assembly as 12/O 1/2008 law. In the lists of rare species in this book,these proposed statuses are listed in parentheses below the current status. Only those proposed statuses that are different from the current statuses are listed. FEDERALSTATUS These statuses are designated by the US Fish and Wildlife Service. Federally listed Endangered and Threatened species are protected under the provisions of the Endangered Species Act of 1973,as amended through the 100th Congress. Unless otherwise noted, definitions are taken from the Federal Register,Vol. 56,No. 225,November 21, 1991 (50 CFR Part 17). CODE STATUS DEFINITION E�Endangered A taxon "in danger of extinction throughout all or a significant portion of its range." ❑Threatened A taxon "likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range." EXN Endangered,nonessential The Endangered Species Act permits the reintroduction of endangered animals as experimental population. "nonessential experimental" populations. Such populations, considered nonessential to the survival of the species, are managed with fewer restrictions than populations listed as endangered. T Threatened due to The Endangered Species Act authorizes the treatment of a species (subspecies or (S/A) Similarity of population segment) as threatened even though it is not otherwise listed as threatened i£ Appearance. (a) The species so closely resembles in appearance a threatened species that enforcement personnel would have substantial difficulty in differentiating between the listed and unlisted species; (b)the effect of this substantial diff�iculty is an additional threat to a threatened species; and (c) such treatment of an unlisted species will substantially facilitate the enforcement and further the policy of the Act. The American Alligator has this designation due to similarity of appearance to other rare crocodilians. The Bog Turtle (southern population)has this designation due to similarity of appearance to Bog Turtles in the threatened northern population. ❑Candidate. A taxon under consideration for which there is sufficient information to support listing. This category was formerly designated as a Candidate 1 (C1) species. FSC Federal "Species of (Also called "Species at Risk"). Formerly defined as a taxon under consideration for Concern" which there is insufficient information to support listing; formerly designated as a Candidate 2 (C2) species. PE Proposed Endangered Species has been proposed for listing as endangered. PD Proposed De-listed Species has been proposed for de-listing. GLOBAL AND STATE RANKS These ranks are determined by The Nature Conservancy's system of ineasuring rarity and threat status. "Global" refers to worldwide ranks and "State"to statewide ranks.

Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina This is an addendum to the Natural Resources Report prepared by Kimley-Horn and dated February 4, 2009. 1 Additional Areas Evaluated The additional areas presented in this addendum were evaluated as part of the Wisteria/Clearbrook Drainage Improvements Project (Project) for the purpose of addressing water quality and flooding issues. These areas were added to the original project boundary to address stakeholder concerns and further address issues identified as part of the Feasibility Study and Concept Design report dated November 2009 prepared by Kimley-Horn. The areas include the stream, floodplain, and coastal marsh downstream of Patricia Drive and the drainage from Oak Bluff Lane, and a drainage ditch along Camellia Lane at the top of the project. See Figures 1 and 2. 2 Additional Area Descriptions and Aquatic Resources The following is a description of the additional areas. Please refer to Figures 2, 3, and 4 as well as the Photo Pages in Appendix A. Also, please refer to the original Natural Resources Report. Area below Patricia Drive — The area below Patricia Drive (Figure 2 and 3) includes two residential lots with houses and maintained yards that transition into coastal marsh areas. The stream runs between the properties from Patricia Drive and discharges into the coastal marsh (Figure 3). The two residential lots appear to have been historically filled. The easternmost lot is somewhat lower and includes wetlands in the maintained portion of the lot (Photo 3). There are also wetland fringes surrounding the coastal marsh that include a number of tree species including pine and cypress. These areas transition into the coastal marsh and appear to be tidally influenced. The stream that runs between the properties appears to have been historically straightened and widened. There is also an obvious spoil pile at the point where the stream reaches the coastal marsh on the western side. Most of the area appears to be labeled as Tidal Marsh on the soils map (Figure 4). However, the area appears to have been filled for an existing residence and residential lot. It is important to note that the area proposed for salt marsh creation/restoration is within the Tidal Marsh boundary, as well. Oak Bluff Lane Area — The additional project area around Oak Bluff Lane includes the drainage collection system adjacent to Oak Bluff Lane and a drainage swale/ditch that runs from Oak Bluff parallel to Ruxton Way to the previous project boundary. The area includes disturbed maintained open space as well. The road collection system discharges to a man-made swale/ditch (Photo 4). The ditch mostly contains tree and shrub species. The hydrology for the system is fed by the road drainage system and well as some groundwater for at least part of the year. There is a berm adjacent to the ditch that eventually connects to a stormwater pond berm. The ditch ends at a blocked 12" CMP that discharges through a berm into a separate small, man-made pond that appears to be an amenity (Photo 5). There is no obvious discharge conveyance from the pond. The USACE determined that both the ditch bottom and small ornamental pond are not jurisdictional since they appear to be located in mostly Seagate soils and constructed through high ground. 1 ��� Kimley-Hom � and Associates, Inc. Natural Resources Report Wisteria/Clearbrook Drainage Improvements Project Wilmington, North Carolina Ditch adjacent to Camellia Lane — The ditch adjacent to Camellia Lane is an open channel with grass and herbaceous vegetation-lined banks (Photo 6). The ditch bottom appears to be below the water table. The ditch runs between residential lots and Camellia Lane. The hydrology for the ditch appears to be mostly from the groundwater table. Partial blockage of the culvert beneath 58th Street may also be contributing to the standing water in the ditch. The culvert connects to the stream at the top of the Project study area. The ditch is located in Seagate and Kureb soils (Figure 4). The USACE determined that this ditch is not jurisdictional. The locations of the additional streams and wetlands identified in this report were reviewed by the USACE, NCDCM, and NCDWQ on February 17, 2010 and March 18, 2010. The approved jurisdictional determination by the USACE is provided in Appendix B. Wetland mapping has been updated to reflect comments from NCDCM that sporadic coastal wetlands were identified along the stream edges up to just past Clearbrook Drive. As a result, it is expected that the AEC will extend 75 feet from the downstream end of the culvert under Clearbrook Drive. The identification methods are the same as those used for the original delineation. Figure 3 shows the location of the jurisdictional areas within the study area. 3 Cultural Resources Based on preliminary site plans, the Division of Cultural Resources (DCR) has expressed concern regarding a potential site in the area of Weeping Willow Drive. As a result, further coordination with DCR is pending. 4 Threatened and Endangered Species Formal consultation with USFWS and the N.C. Natural Heritage Program (NCNHP) has not been completed as part of this project, and no written correspondence has been obtained. Coordination with these agencies is anticipated as part of the CAMA Major Permitting process. The USFWS has listed one additional endangered species in New Hanover County since the previous report was finalized, Thalictrum cooleyi—Cooley's meadowrue. 5 Permitting The Division of Coastal Management has indicated that a CAMA Major Permit will be required for the project during the above field visits. This is based on the impacts from the proposed culvert replacements and marsh creation activities. 6 Summary In summary, the additional project area has similar characteristics to that of the original project area. Because of the need for a CAMA Major Permit, it is anticipated that all of the necessary coordination and environmental issues will be addressed. 2 ��� Kimley-Hom � and Associates, Inc.

Bald and Golden Ea�le Protection Act (BGPA� In the July 9, 2007 Federal Register(72:37346-37372), the bald eagle was declared recovered, and removed (de-listed)from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, the Bald and Golden Eagle Protection Act(Eagle Act) (16 U.S.C. 668-668d)becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of"take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit http://www.fws. og v/mi ra�birds/baldea lg e.htm Threatened due to similarity of a�pearance(T(S/A�: In the November 4, 1997 Federal Register(55822-55825), the northern population of the bog turtle (from New York south to Maryland)was listed as T (threatened), and the southern population (from Virginia south to Georgia)was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of the bog turtle as a Federal species of concern due to habitat loss. Definitions of Record Status: Current-the species has been observed in the county within the last 50 years. Historic - the species was last observed in the county more than 50 years ago. Obscure -the date and/or location of observation is uncertain. Incidental/migrant -the species was observed outside of its normal range or habitat.

Page 1 of 4 EXPLANATION OF CODES FOR COUNTY AND QUAD STATUS LISTS The county and quadrangle status lists provided by the NC Natural Heritage Program tally the elements of natural diversity(rare plants and animals,rare and exemplary natural communities,and special animal habitats)known to occur in all Narth Carolina counties and USGS 7.5-minute quadrangles. The information on which these lists is based comes from a variety of sources, including field surveys,museums,herbaria,scientific literature,and personal communications. These lists are dynamic,with new records continually being added and old records being revised as new information is received.As a result,a list cannot be considered a definitive record of the elements of natural diversity present in a given county or quad and should not be used as a substitute far field surveys. When this information is used in any document,we request that the date this list was compiled be given and that the NC Natural Heritage Program be credited. STATESTATUS CODE STATUS CODE STATUS E�Endangered SR Significantly Rare T�Threatened EX Extirpated SC Special Concern�Proposed(used only as a qualifier of the ranks above) 0 Candidate NOTE: the definitions of state statuses of plants and animals differ.Below are summaries of the statuses for each group. Plant statuses are determined by the Plant Conservation Program(NC Department of Agriculture)and the Natural Heritage Program(NC Department of Environment and Natural Resources).Endangered,Threatened,and Special Concern species are protected by state law(Plant Protection and Conservation Act, 1979). Candidate and Significantly Rare designations indicate rarity and the need for population monitoring and conservation action.Note that plants can have a double status,e.g.,E-SC, indicates that while the plant is endangered,it is collected or sold under regulation. CODE STATUS DEFINITION E Endangered "Any species or higher taxon of plant whose continued existence as a viable component of the State's flora is determined to be in jeopardy° (GS 19B 106: 202.12). (Endangered species may not be removed from the wild except when a permit is obtained for research,propagation,or rescue which will enhance the survival of the species.) T Threatened "Any resident species of plant which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range° (GS 19B 106:202.12). (Regulations are the same as for Endangered species.) SC Special "Any species of plant in North Carolina which requires monitoring but which may be collected Concern and sold under regulations adopted under the provisions of[the Plant Protection and Conservation Act]° (GS 19B 106:202.12). (Special Concern species which are not also listed as Endangered ar Threatened may be collected from the wild and sold under specific regulations. Propagated material only of Special Concern species which are also listed as Endangered or Threatened may be traded or sold under specific regulations.) C Candidate Species which are very rare in Narth Carolina,generally with 1-20 populations in the state, generally substantially reduced in numbers by habitat destruction(and sometimes also by direct exploitation or disease). These species are also either rare throughout their ranges(fewer than 100 populations total)or disjunct in North Carolina from a main range in a different part of the country or world. Also included are species which may have 20-50 populations in North Carolina,but fewer than 50 populations rangewide. These are species which have the preponderance of their distribution in North Carolina and whose fate depends largely on their conservation here. Also included are many species known to have once occurred in North Carolina but with no known extant occurrences in the state (historical or extirpated species);if these species are relocated in the state,they are likely to be listed as Endangered ar Threatened. If present land use trends continue,candidate species are likely to merit listing as Endangered or Threatened. SR Significantly Species which are very rare in Narth Carolina,generally with 1-20 populations in the state, Rare generally substantially reduced in numbers by habitat destruction(and sometimes also by direct exploitation or disease). These species are generally more common somewhere else in their ranges,occurring in North Carolina peripherally to their main ranges,mostly in habitats which are unusual in North Carolina.Also included are some species with 20-100 populations in Narth http://149.168.1.196/nhp/codes.html 3/12/2010 NC NATURAL HERITAGE PROGRAM COLTNTY or QUAD STATUS LIST COVER ... Page 2 of 4 �� �Carolina,if they also have only 50-100 populations rangewide and are declining. � -L Limited The range of the species is limited to North Carolina and adjacent states(endemic or near endemic). These are species which may have 20-50 populations in North Carolina,but fewer than 50 populations rangewide. The preponderance of their distribution is in North Carolina and their fate depends largely on conservation here. Also included are some species with 20-100 populations in North Carolina,if they also have only 50-100 populations rangewide and declining. -�T Throughout These species are rare throughout their ranges(fewer than 100 populations total) -�D Disjunct The species is disjunct to NC from a main range in a different part of the country or world. -P Peripheral The species is at the periphery of its range in NC. These species are generally more common somewhere else in their ranges,occurring in North Carolina peripherally to their main ranges, mostly in habitats which are unusual in Narth Carolina. �Other The range of the species is sporadic or cannot be described by the other Significantly Rare categories �Proposed A species which has been formally proposed for listing as Endangered,Threatened,or Special Concern,but has not yet completed the legally mandated listing process. Animal statuses are determined by the Wildlife Resources Commission and the Natural Heritage Program. Endangered, Threatened,and Special Concern species of mammals,birds,reptiles,amphibians,freshwater fishes,and freshwater and terrestrial mollusks have legal protection status in North Carolina(Wildlife Resources Commission). The Significantly Rare designation indicates rarity and the need for population monitoring and conservation action. CODE STATUS DEFINITION E Endangered "Any native or once-native species of wild animal whose continued existence as a viable component of the State's fauna is determined by the Wildlife Resources Commission to be in �eopardy or any species of wild animal determined to be an'endangered species'pursuant to the Endangered Species Act.° (Article 25 of Chapter 113 of the General Statutes; 1987). T Threatened "Any native or once-native species of wild animal which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range,or one that is designated as a threatened species pursuant to the Endangered Species Act.° (Article 25 of Chapter 113 of the General Statutes; 1987). SC Special "Any species of wild animal native or once-native to Narth Carolina which is determined by the Concern Wildlife Resources Commission to require monitoring but which may be taken under regulations adopted under the provisions of this Article.° (Article 25 of Chapter 113 of the General Statutes; 1987). SR Significantly Any species which has not been listed by the N.C. Wildlife Resources Commission as an Rare Endangered,Threatened,or Special Concern species,but which exists in the state in small numbers and has been determined by the N.C.Natural Heritage Program to need monitoring. (This is a N.C.Natural Heritage Program designation.) Significantly Rare species include "peripheral" species,whereby Narth Carolina lies at the periphery of the species'range(such as Hermit Thrush). The designation also includes marine and estuarine fishes identified as "Vulnerable"by the N.C. State Museum of Biological Sciences(Ross et al., 1988,Endan e�red Threatened,and Rare Fauna of Narth Carolina.Part IL A Reevaluation of the Marine and Estuarine Fishes). EX Extirpated A species which is no longer believed to occur in the state. P Proposed Species has been proposed by a Scientific Council as a status(Endangered,Threatened, Special Concern,Watch List,ar for De-listing)that is different from the current status,but the status has not yet been adopted by the Wildlife Resources Commission and by the General Assembly as law. In the lists of rare species in this book,these proposed statuses are listed in parentheses below the current status. Only those proposed statuses that are different from the current statuses are listed. FEDERALSTATUS These statuses are designated by the US Fish and Wildlife Service.Federally listed Endangered and Threatened species are protected under the provisions of the Endangered Species Act of 1973,as amended through the 100th Congress.Unless otherwise noted,definitions are taken from the Federal Register,Vol. 56,No. 225,November 21, 1991 (50 CFR Part 17). http://149.168.1.196/nhp/codes.html 3/12/2010 NC NATURAL HERITAGE PROGRAM COLTNTY or QUAD STATUS LIST COVER ... Page 3 of 4 CODE STATUS DEFINITION �Endangered A taxon"in danger of extinction throughout all or a significant partion of its range." �Threatened A taxon°likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range." EXN Endangered,nonessential The Endangered Species Act permits the reintroduction of endangered animals as experimental population. "nonessential experimental"populations. Such populations,considered nonessential to the survival of the species,are managed with fewer restrictions than populations listed as endangered. T Threatened due to The Endangered Species Act authorizes the treatment of a species(subspecies or (S/A) Similarity of population segment)as threatened even though it is not otherwise listed as threatened if: Appearance. (a)The species so closely resembles in appearance a threatened species that enforcement personnel would have substantial difficulty in differentiating between the listed and unlisted species;(b)the effect of this substantial difficulty is an additional threat to a threatened species;and(c)such treatment of an unlisted species will substantially facilitate the enforcement and further the policy of the Act. The American Alligator has this designation due to similarity of appearance to other rare crocodilians. The Bog Turtle (southern population)has this designation due to similarity of appearance to Bog Turtles in the threatened northern population. �Candidate. A taxon under consideration for which there is sufficient information to suppart listing. This category was formerly designated as a Candidate 1 (C1) species. FSC Federal"Species of (Also called"Species at Risk").Formerly defined as a taxon under consideration for Concern" which there is insufficient information to suppart listing;formerly designated as a Candidate 2(C2) species. PE Proposed Endangered Species has been proposed for listing as endangered. PD Proposed De-listed Species has been proposed for de-listing.

The issue is related to outfall discharges into SA waters. Description of project: A drainage improvement project in a fully developed area that outfalls into an SA water where flooding is a primary concern. Drainage culverts need to be replaced because they are old and undersized. No increase in impervious area is occuring, in fact it will be reduced. Following the progression of the rules: Disturbance greater than 1 acre==> Erosion control permit =_> Based on SB1967 sect 2b - this project would need to comply with the rules Section 2(d)3 states that redevelopment is excluded as long as there is no increase in impervious area and management of stormwater is equal or improved. My recollection of our discussions when these rules were being drafted and I brought this specific concern to your attention, was that this type of project described above would be excluded based on the redevelopment definition. Again, we will not be increasing impervious as stormwater managment will be improved. I would appreciate some feed back from you on this issue. Thanks David B. Mayes, P.E.
