PROPOSED STREAMBANK AND RIPARIAN BUFFER PLANTING I - IV- I I I I I I I I I I I I I I I I I I !I I 1.0 INTRODUCTION The subject reach, an unnamed tributary of Wildcat Branch (a tributary of Walnut Creek) is located immediately west of Hammond Street in south Raleigh, NC. This reach is proposed to be relocated and restored in order to accommodate the proposed widening of Hammond Road near its intersection with Rush Street. 1.1 Report Summary This report has been prepared by Soil & Environmental Consultants, P A (S&EC) in order to describe the Stream and Wetland Restoration efforts associated with the stream relocation on the Hammond Street Road Widening Project. The proposed relocation and restoration plan will be fundcd and completed by Marjan Limited of Raleigh, NC, which currcntly owns the property, a significant portion of which is proposed for development. The restored stream, crcated wetlands, and riparian buffer acrcage created will be protected through a rccorded conservation easement. 1.2 Project Location The project site is located immediately northwest of the intersection of Hammond Street and Rush Street in southern Raleigh, North Carolina (Wakc County). The total property is under thc sole ownership of Marjan Limited and consists of approximately 49.7 acres (+/-) much of which is currently under development for mixcd commcrcial usc. See Figurc I for a Vicinity Map. See Figures 5 and 6 for an overall map of subject property and the proposed construction boundary. 1.3 Site Description The subject reach consisting of approximately 510 linear fect of perennial stream channel is currently in a modified and unnatural state. The tributary currently flows northeast as it enters the site, and turns due north as it parallels Hammond Road, hugging the toe of the road fill slope for the length of the project site. Sce Appendix A for Existing Site Photographs. At the downstream (north) end of the restoration rcach the stream outfalls to Wildcat Branch through an cxisting 36-inch diameter reinforced concrete pipe (RCP). This pipc carries flow beneath an existing unpaved site access road (to rcmain) and daylights through thc left wingwall (left and right arc rcferenccd whilc looking downstream) of the headwall for an existing series of concrete box culverts. These box culverts convey Wildcat Branch beneath Hammond Road in a southeast to northwest direction. No outlet protection currently exists at the outfall ofthc box culverts, and significant scour has occurred within the channel bed immediately downstrcam (scc Appcndix A - Photo 8) - I - I I I I I I I I I I I I I I I I I I I exposing the culvert foundation. The 36-inch pipe in its currcnt configuration is suspcnded (approximately 24-inches) above the downstream channel bed (sec Photo 9). The eastern edge of the stream consists ofa steep bank (fill slope of Hammond Road) with moderately dense vcgctation including a few sporadic large hardwood trecs and mixed understory vegetation. Thc western edge of the strcam has a narrow wooded buffer ncar the upstream cnd ofthc reach tapcring (in a downstream direction) to a thin stand of woody vegetation immediately to the west of the existing channel. An existing sanitary sewer line parallels the wcstern boundary of the site immediately adjacent to a serics of existing private residences. See Figure 6 for a description of the existing site conditions. The current conditions of the strcam are mainly the result of historical modifications including channelization and likely as a result of the construction of Hammond Road and subsequcnt road widening operations. Much of the site has undergonc localizcd disturbance associated with previous activities including homc construction and utility installation. Preliminary hand auger borings indicatc that portions ofthc site may also have been used for quarry and waste operations. In addition to the perennial stream channel on the property, a total of 0.218 acres (or 9,504 square feet) of jurisdictional wetlands also exist on the property. Ofthis,0.133 acres (or 5,812 square feet) will be impacted through the proposed widening of Hammond Road. See Appendix F for a copy of the site Jurisdictional Waters Delineation performed by Soil & Environmental Consultants, P A, and surveyed by Smith and Smith Surveyors. 1.4 Project Background In May 2004, Soil & Environmental Consultants, P A, (S&EC) was engaged by Marjan Limited to provide environmental consulting and engineering services associated with the relocation of the stream as previously described. On August 19,2004, S&EC met with Ms. Jennifer Burdette of the U.S. Army Corps of Engineers (USACE), Raleigh Office, and Mr. Bob Zarzecki of the North Carolina Department of Environment and Natural Resources (NCDENR), Division of Water Quality (DWQ), Raleigh Office, to observe site conditions, verify the previously prepared Jurisdictional Waters Delineation, review our findings to date, and discuss our proposed approach for the relocation and restoration efforts at the site. During our site mecting, Agency representatives indicated general concurrence with the proposed relocation and restoration plan, and provided valuable comments and input which we subsequently incorporated into this Conceptual Restoration Plan. After our site visit, we also visited the refercncc reach site with both USACE and DWQ representatives. Both Agencies agreed with the suitability of our selected site as a refcrence condition for use on this projcct's natural channel design component. - 2 - I I I I I I I I I I I I I I I I I I I 1.5 Project Objectives The current channelized and degraded state of the stream, limited floodplain functionality due to channel incision, existing and future scdimentation and erosion potential, and limited native vegetation along the banks and riparian buffer zone indicate, even without the desired relocation, that this length of stream presents a viable restoration project. This restoration plan proposes to construct a stream channel that is stable and self- maintaining, and that will not aggrade or degrade over time, by utilizing Rosgen-based natural channel design procedures and techniques. In this proccss we intend to accomplish the following objectives: I) Develop a restored channel with the appropriate morphological characteristics (cross-sectional dimension, pattern, and longitudinal profile) utilizing locally collected refercnce reach data as a guide. Allow for no net loss of overall channel length in the process. 2) Create and/or improve bed form diversity (riffles, runs, pools, and glides) and improve aquatic and benthic macroinvertebrate habitat. 3) Construct a floodplain (or local bankfull bench) that is accessible at the proposed bankfull channel elevation. 4) Ensure channel and stream bank stabilization by integrating in-stream structures and native vegetation. 5) Establish a native forested or hcrbaceous riparian plant community within a minimum of30 feet, when possible, from the edge of the restored rcach. This ncw community will be established in conjunction with the eradication of exotic and/or undesirable plant species. 6) Allow for no net loss of riparian wetlands through the creation of an equivalent acreage (0.133 acres) of similar wetlands within the newly established floodplain. Provide a more desirable wetland vegetative community. 7) Integrate the rcstoration site into the overall development plan providing aesthetic and education values. It is our intent to ensure that our client's goals, as well as those of the Agencies, are incorporated into the planning process and that all necessary permitting requirements are met. Permitting actions and permit applications (401/404) will be compiled under separate correspondence by Soil and Environmental Consultants, P A. - 3 - I I I I I I I I I I I I I I I I I I I 1.6 Authorization These services were authorized by acceptance of S&EC Short Form Proposal 7238.D 1, dated March 10, 2004, and signed by Mr. Victor E. Bell, III, of Mmjan Limited of Raleigh, NC, on May 21, 2004. 1.7 Scope of Services Our scope of services was divided into data collection, engineering analysis, conceptual design development, project coordination, and report preparation to include the following: I. We performed a Preliminary Site Evaluation including the location of and preliminary review and evaluation of available site mapping to include USGS 7.5 Minute Quad sheets, Digital Orthophoto Quad (DOQ) sheets, and County Soils Survey map sheets. We researched available hydrologic and hydraulic data for the project site including a review and evaluation of available regional curve data. 2. We visited the sitc for thc familiarization with site features and characterization of site soils and vcgetation, and general conditions. Whilc on sitc we performed a serics of shallow (hand auger) soil borings at selcct locations along the proposed restored alignment to develop an understanding of typical sitc soil conditions. We observed plant community types for use in a qualitative plant community assessment. We observed the characteristics of the site and surrounding area, verified surface and channel flow conditions, and observed existing property boundaries, utilities, water conveyance structures, and other site constraints. 3. We identified and evaluated a natural channel reference reach to be used in the restored channel design process. We performed a characterization ofthc reference reach including watershed assessment, sitc mapping and drainage area calculation, determination of bankfull stage, morphological data collection including a longitudinal profilc and cross-section data collection, and channel substrate evaluations. 4. We developed an inventory of pertinent sitc features and performed a limited engineering site survey using Total Station for incorporation with available site topographic, service, and utility data. We perfonncd a morphological cvaluation to includc thc collection of rough longitudinal profilc and cross- section data and channel substrate data. - 4 - I I I I I I I I I I I I I I I I I I I 5. We analyzcd data collected from the project site (existing reach and restoration alignment) and the referencc reach for the development of this Conceptual Restoration Plan. 6. We met on site with representatives of both USACE and NCDENR (Division of Water Quality) to discuss our concept for the stream and wetland restoration. We incorporated agency input, and using our analyses we developcd this Conceptual Restoration Plan. 1.8 Future Design & Consulting Effort Future design efforts to be completed upon review and approval of our Conceptual Restoration Plan by Agency rcpresentatives include: I. The preparation of final construction drawings (prepare site plan, construction details, planting plan, and erosion and sediment control plan), technical specifications, and a construction sequence. 2. Construction related tasks including a pre-construction meeting, contractor coordination, daily construction observation, planting observation, and a post construction review with the Contractor and Agency representatives. 1.9 Project Personnel Environmental site evaluations and restoration planning have been perfonned solely by Soil & Environmental Consultants, P A, of Raleigh, NC. Project personnel included: Patrick K. Smith, P.E., Project Manager, and J. Michael Ortosky, RLA, LSS, Design Lead, Peter A. Jelenevsky, Strcam Restoration Specialist, Rebccca Wargo, EIT, Stream Restoration Specialist, Sean Clark, Wetland Scientist, and Elizabeth G. Turner, PLS, Professional Surveyor. The design enginecrs for the projcct are Jones & Cnossen Engineering, PLLC, of Raleigh, NC. Survey and topographic site data were providcd by Smith and Smith Surveyors of Apex, NC. - 5 - ,I I I I I I I I I I I I I I I I I I I 2.0 STREAl\'I RESTORATION The purpose of this section is to summarize our analyses to date of the subject stream reach proposcd for relocation and provide a conceptual plan for its restoration. This section provides a general description ofthe design approach for the proposed stream restoration; however, details of the restoration plan, including construction drawings and technical specifications, will be included in a later document once concurrence of our gencral design approach is received from USACE and NCDENR-DWQ represcntatives. 2.1 \Vatershed Characteristics 2.1.1 General Description The project site sits approximately two miles due south of the City of Raleigh, NC. The surrounding landscape topography is charactcrized as gently rolling to steep or hilly terrain, with side slopes that are generally steep to moderately sloping. Watershed elevations range from approximatcly 240 fect to 335 feet as shown on the USGS 7.5 Minute Scrics Topographic Map (Lake Whecler, NC). See Figure I. Past development activities, including road construction, culvcrt installation, and sanitary sewer line installation have partitioned the site and redirccted the channcl from its natural course. Prior to its manipulation (including the construction of Hammond Road and Rush Street) the valley type for Wildcat Branch and the subject tributary would likcly have bccn categorized as Valley Typc VIII as defincd in Applicd River Morphology (Rosgcn 1996), consisting of a wide, gently sloping valley with a well-dcfined floodplain. 2.1.2 Surface 'Vaters The channel is located within the Neuse River Basin, USGS Hydrologic Unit 0302020 I. The unnamed tributary flows immcdiately into Wildcat Branch (Stream Index Number 27-34-7) aftcr exiting the existing culvert pipe. Approximately one mile downstream, Wildcat Branch discharges into Walnut Creek (Stream Index Number 27-34-(4)), a tributary of the Neuse Rivcr. We understand that the North Carolina Division of Water Quality (NC DWQ) has not assigncd a stream index number to unnamed tributary proposed for restoration. The currcnt State classification of both Wildcat Branch and Walnut Creek (at that location) is Class C NSW waters (NCDENR 05/01/1988). Class C waters are freshwatcrs protcctcd for secondary rccreation, fishing, and aquatic life including propagation and survival, and wildlifc. The NSW designation is a Nutrient Sensitivc Waters which are subject to microscopic or macroscopic vegctation rcquiring limitations on nutrient inputs. - 6 - I I I I I I I I I I I I I I I I I , I I 2.1.3 Soils The restoration site is located in the Felsic Crystalline System of the Piedmont physiographic region of North Carolina. According to the published soils survey for Wake County (USDA Soil Conservation Service - November 1970) associated soils in this arca consist of Cecil soils, gently sloping to steep, deep, well-drained soils that have a subsoil of firm rcd clay; dcrived mostly from gneiss and schist. Specific inspection of the mapped soils within the contributing watershed indicate primarily Cecil (Ce) Sandy Loam soils of varying slopes (2 to 15 pcrcent) as well as a lesser portion of Appling (Ap) Sandy Loam mapped on site. Floodplain soils within the restoration area consist primarily of Chewacla (Cm) and Colfax (Cn) soils. See Figure 2. 2.1.4 Land Use Currcntly, the project site remains unused with the exccption of the perimeter services and utilities previously described. The majority of the surrounding watcrshed area has previously been converted to housing (apartments and single family homes), light commcrcial, and infrastructure uses (roads, parking lots, etc.). Areas of forest land exist sporadically throughout thc watershed. The upper end of the watcrshed includcs a small portion of the Montlawn Memorial Park Cemctery. Although select portions of the watershed appear to have been developed within the last 5 to 10 ycars, based on observation, the majority of the watershed was developed many years ago. Limited opportunity for future development exists within the watershed. Based on current land usage, impervious arca is estimated at approximately 25 to 35 percent. 2.2 Existing Stream Conditions This section provides preliminary data regarding the existing channel based on site data collected and our evaluation to date. 2.2.1 Geomorphic Position The site topography is relatively flat adjacent to the stream where landscape modifications have not occurred ranging in elevation from approximately 240 feet to 250 feet. Soils present in the riparian areas adjacent to cxisting channel and along the proposed channel alignment consist ofChewacla (Cm) and Colfax Sandy Loam (Cn) soils. Extensive grading and filling associated with local construction (and other) operations has likely modified much of the naturally occurring soils in the vicinity of the restoration project. Chewacla soils (Aquic Fluvelltic Dystroclzrepts) are the prevalent map unit along the channel. Formed in high alluvial deposits of fine loamy material, they are somewhat poorly drained. They typically have low natural fertility and organic matter content. - 7 - i II I !I I I I I I I I I I I II I ,I I I I Colfax soils (Aquic Fragiudults) arc prcsent along the channel to a lesser extent. These soils arc also fonned under forest, in translocated matcrial, from weathered rock, and are somewhat poorly drained with low natural fertility and organic matter content. 2.2.2 Site Hydrology The reach proposed for restoration flows generally south to north towards the tributary's confluence with the Wildcat Branch. Based on the most recent USGS quadrangle the subject channel is a First Order stream and thc drainage area at the terminus ofthc project is approximately 0.143 square miles (mi.2). 2.2.3 Data Collection A field reconnaissance of the restoration site was performed on June 18, 2004, prior to thc commencement ofthc site survey and data collection. During our subsequent sitc visits on July I, July 9, and September 29,2004, we collected a variety of topographic and site data in the vicinity ofthe restoration reach. Topographic data was collected through a limited engineering survey using Total Station equipment. Data collectcd includcd: 1. A limited longitudinal profile of the existing reach from thc approximate property boundary at the upstream end of the site to the inlct of the cxisting pipe culvert beneath the site access road. 2. Three typical channel cross-sections describing thrce distinctly different reaches of the existing channel (upper, middle, and lower - described below). Each cross-section was oriented perpendicular to the direction of flow and surveyed from left to right looking downstream. 3. Various topographic data points including but not limited to existing ground surface points, culvert inverts, water surface elevations, fill slopes, and select utilities. 4. Select topographic reference points (installed by Smith & Smith Surveyors) for tie-in with sitc data provided by Jones & Cnossen, PLLC, and confirmation of horizontal location of collected topographic data. 5. Substrate material evaluations (pebble counts) at each of the three aforementioned cross-sections. 6. A photographic record of existing site conditions. - 8 - I I I I I I I I I I I I I I I I I I I Soil & Environmental Consultants, P A surveyed the existing channel conditions and integratcd our data with Wakc County Topographic Mapping data (2-foot contours) of the restoration site. Thc map was used to evaluate present landscape conditions and constraints to determine the final location of the proposcd channel alignment and floodplain configuration. Our topographic data was later overlain on available site data provided by Jones & Cnossen Engineering, PLLC, for use in the developmcnt of this restoration plan. Site photos arc provided in Appendix A. 2.2.4 Stream Morphology Available mapping mcasures the length of channel proposed to be rclocated and rcstored at approximately 510 linear feet of channel (sce delineation map). Limited discemable bed form appears throughout the existing channel reach due to various channel modification and off-site influenccs. Thc majority of the longitudinal profile resembles a riffle/run bed with few pools as is shown on the longitudinal profile. The existing stream consists ofthrce distinct channel segments; thc uppcr rcach approximately 60 feet in length, the middle reach approximately 150 feet in length, and the lower reach approximately 300 fect in length. Thc uppcr reach consists of a transitional zone which receives flow from off site. This reach has bccn severely manipulated due to thc original construction, and subsequent improvement of the sanitary sewer line. This reach is characterized by significant scdiment deposition and has varied drastically in appearance and dimension since the time of our original site visit in May 2004. Banks along this segment are void of stabilizing vegetation and eroded. The middle reach is characterized by significant sediment deposition, in excess of that observed upstream. This reach has also varied in appcarance somewhat over our evaluation period; however, its general dimension has remained fairly consistent. This reach bisects a portion of delineated wetlands and is fairly well vegetated. The lower rcach, while channelized, generally appcars in a more stable condition than the other two reaches. This reach is has maintained a uniform in appearance and dimension along its length throughout our study period. Dense vegetation covers both banks and overhangs much of the stream channel along this lower stream segment. Valley fall (downvallcy) from the project origin to end of the proposed reach (just upstream of the channel's confluence with Wildcat Branch) is just over 3 feet, resulting in a valley slope of approximately 0.77 percent (0.0077 ftlft) based on the available topographic mapping. Channel fall (at the invert) is just over 4 feet, resulting in a channel slope of approximately 0.75 percent (0.0075 ftIft) based on - 9 - I I I I I I I I I I I I I I I I ,I :1 I collected field data. The calculated sinuosity (Valley Slope / Channel Slope) is 1.03 and is considered rcasonable bascd on ficld observation of the straightened channelized reach which parallels Hammond Road's toe of slopc. Plots of the existing reach longitudinal profile, cross-section data, and pebblc count data for each cross-section havc been prepared. Please refer to Appendix B for data on the existing stream channel. 2.2.5 Stream Classification Thc channel was classified utilizing thc stream classification system developed by Dave Rosgen (Rosgen 1996). This classification schcmc utilizes scveral parameters based on field collected data and site observation, which collectively determines the stream type. The criteria utilized to determine stream type includes the slope, width/depth ratio, entrenchment ratio, sinuosity, and bed materials. Based on the degraded and non-unifonn condition ofthc cxisting channel reach, the morphological characteristics described in Appendix B should only be used as a general description of channel form. Utilizing the Rosgen Stream Classification System (as possible), the upper-most portion of the channel has bcen classified as an "E4" (bed material Dso of 3.6 mm - gravel) typc channel, the middle portion classified as an "E5" (bcd material Dso of 0.1 0 mm - sand), and the lowermost section classifies as an "E4" (bed matcrial Dso of7.4 mm - gravel) type channcl. The current channel is in a degraded and somcwhat incised state, particularly at its uppcr end, and therefore flood flows are concentrated within the channel. Over much of the reach the floodplain is not readily accessible at the field determined bankfull elevation. 2.3 Reference Stream Condition The reference reach used in our design is an unnamed tributary to Middle Creek in southwestern Wake County, NC, approximately 2 miles northeast of the Town of Holly Springs. This section provides preliminary data regarding the reference reach based on site data collected and our evaluations to date. 2.3.1 Geomorphic Position The reference reach topography is relatively flat adjacent to the stream wherc landscape modifications have not occurred ranging in elevation from approximately 320 feet to 330 feet as shown on the USGS 7.5 Minute Scries Topographic Map (Apex, NC). See Figurc 3. According to the Wake County Soils Survey, soils present in the riparian areas adjacent to existing reference reach consist ofWehadkee (Wn) Silt Loam soils. - 10- I I I I I I I I I I I I I I I I I I I Wehadkee soils (Fluventic Haplaquept) are the prevalent map unit along the channel. Thesc soils are formed in finc loamy alluvial deposits and are poorly drained. Sec Figure 4. The wooded areas to either side of the channel appear undisturbed (in recent history bascd on the sizc and dcnsity of woody specics). 2.3.2 Site Hydrology The rcference reach flows gencrally south towards its confluencc with Middle Creek. Based on the most recent USGS Quadranglc, the reference reach is a First Order stream and the drainage area at the tenninus of the project is approximately 0.142 squarc miles (mi2). 2.3.3 Data Collection A field reconnaissance of the channel was pcrformed on Junc 18, 2004, prior to the commcncement ofthc sitc survcy. The purpose of the reconnaissance is to identify the bankfull elcvation utilizing existing indicators. Featurcs that were utilized when present included depositional features, vcgetation positions, scour lines, and wrack lines. During our subsequcnt site visit to the reference reach on July 1,2004, wc collectcd a variety of topographic and site data in the vicinity of the reference reach. Topographic data was collected through the conduct of a limited cnginecring survcy using Total Station equipment. Thc exact elevations along the refercnce reach are not known as all data collccted at this site was rclative to an assumed temporary bcnchmark elevation of 100.00 fect. Referencc reach data included the collection: 1. A longitudinal profilc for approximately 250 linear feet (20 to 30 bankfull widths as desired) of reference stream channel. 2. Two riffle and two pool cross-sections werc surveyed. Each cross-section was oricnted perpendicular to the dircction of flow and surveyed from left to right looking downstream. 3. Various topographic data points including but not limited to existing ground surface points and water surfacc elevations. 4. Substrate material evaluations (pebblc counts) were taken at each rifflc and pool cross-section. A representativc pebblc count was also pcrformed. 5. Photographic record of the reference reach site. - II - ,I I I I I I I I I I I I I I I I I I I Our reference data was later compiled for use in the evaluation of our reference reach and the development of this restoration plan. 2.3.4 Refercnce Reach Stream Morphology The reference reach was generally consistent in dimension (riffles and pools), pattern, and profile along the evaluated lengths of approximately 250 linear feet. For classification purposes we estimated that the reach consisted of approximately 40 percent riffles and 60 percent pools. Riffles typically were short and steep, peaking between existing pools as shown in the longitudinal profile. The pools, typically located within meander bends, were long and deep. In some cases compound (multiple connected) pools were observed. Channel banks along the reach are uniformly stable and although steep (and almost vertical at select locations) are well vegetated banks and a significant internal root structure. Little to no erosion was observed along the reference reach segment evaluated. Consistent indications of bankfull elevation were noted during our site evaluation. The two riffle cross-sections surveyed were generally consistent in dimension (cross- sectional area, bankfull width, mean depth, and width/depth ratio) as is shown in the following table: Morphological Riffle No. 1 Riffle No.2 Characteristic Cross-scctional 6.5 6.5 Area, ft.2 Bankfull 8.0 7.3 \Vidth, ft. Mean 0.8 0.9 Depth, ft. \Vidth / Dcpth 10.0 8.2 Ratio - 12 - il I I I I I I I I I I I I I I I I I I The two pool cross-sections were also generally consistent in dimension (cross- sectional area, bankfull width, mean depth, and max depth) as shown below: Morphological Pool No.1 Pool No.2 Characteristic Cross-sectional 18.7 18.9 2 Area, ft. Bankfull 8.3 10.4 \Vidth, ft. Mean 2.3 1.8 Depth, ft. Max. 3.7 3.5 Depth, ft. Based on field measurements of channel length and valley length at the reference reach we calculated a sinuosity (Channel Length / Valley Length) of 1.24 which appears reasonable based on field observation of the reach. The channel slope (based on invert elevation) from field measurements (head of riffle to head of riffle) was calculated at 0.43 percent (0.0043 ft. 1ft.). A series of pebble counts were performed during our site visit including one at each riffle and each pool. A representative pebble counts was also perfonned for classification purposes. Substrate along the reference reach consisted of silt, sand, and gravel materials. The representative pebble count revealed a bed material Dso of 10.1 mm (Gravel). Site photos are provided in Appendix C. Plots of the existing reach longitudinal profile, cross-section data, and pebble count data for each cross-section is provided in Appendix D. 2.3.5 Stream Classification The reference reach was similarly classified utilizing the Rosgen stream classification system utilizes parameters based on field collected data and site observation. Again, the criteria utilized to determine stream type includes the slope, width/depth ratio, entrenchment ratio, sinuosity, and bed materials. Utilizing the Rosgen Stream Classification System, the reference reach was classified as an "E4" type channel. - 13 - I I I I I I I I I I I I I I I I I I I 2.3.6 Regional Curve Verification Using data published by North Carolina Stream Restoration Institute (SRI) (Regional Curves for North Carolina Piedmont Streams - SRI 2000) we compared our reference data expectant riffle dimension characteristics for a stream with a watershed area of 0.14 square miles. Cross-sectional Area, Bankfull Width, and Mean Depth were all compared with the curve line and their placement in relation to the 95% confidence limits (upper and lower) for each of the three curves. The comparisons are presented in the following table: Regional Curve Data Morphological Reference Characteristic Reach Lower Curve Upper Data Limit Line Limit Cross-sectional 6.50 2.40 5.60 10.20 2 Area, ft. Bankfull 7.30 3.10 6.70 10.40 \Vidth, ft. Mean 0.90 0.50 0.88 1.60 Depth, ft. 2.4 Stream & Buffer Restoration The implementation of the restoration plan will result in the development of a stable natural stream channel within a contiguous fully vegetated and protected riparian corridor. In order to perform the necessary stream restoration along the impacted reach, natural channel design methods were employed. This approach is used to develop the appropriate dimension (cross-section), pattern (sinuosity), and profile (channel slope) which naturally occurs in a stable channel in the Piedmont physiographic region of North Carolina. This process incorporates the use of a reference reach for the appropriate valley type and land form. Design includes the evaluation of both water and sediment transport requirements to produce a stable stream in dynamic equilibrium. Restoration of natural channel geometry and structure will not only improve water quality and habitat within the immediate channel environment but also in the downstream channel as well. Stream banks will be planted with native vegetation that represents both woody (trees and shrubs) and herbaceous species. Species selection was based on a - 14- I I I I I I I I I I I I I I I I I I I survcy ofthc vcgctation from thc rcferencc reach and from rcfercncc litcraturc that dctails nativc spccics. Restoration of a suitablc riparian buffer will cnhancc thc rccovery and protcction of thc restorcd strcam. A protcctcd buffcr (minimum of30 fcct, 50+ fcet where possiblc) will bc restorcd on both sides of the channel rcstoration reach. The wooded corridors that will bc cstablishcd as part of this restoration will also incrcasc the vertical and horizontal structurc perpcndicular to the channcl along thc rcach helping to incrcasc species composition and abundance. Additionally, thc prcscnce of a woodcd buffcr parallcl to the channel not only incrcascs in-stream habitat quality by cooling watcr and incrcasing oxygcn content, it also provides cover, travcl corridors, and acccss to adjaccnt natural arcas for upland and avian specics. 2.5 Natural Channel Design The rcstoration design for thc sitc strcam is based on natural channel design principlcs and techniques utilizing rcfcrcnce rcach data and the cxisting channcl conditions survey data. Rcfcrence data utilizcd in our design includes the unnamed tributary to Middle Creek (as previously described) and North Carolina Rural Piedmont Regional Curvc (SRI 2000). The proposed stream design will restore a naturally meandering E type stream channel to a more appropriate location based on the current site constraints as depicted on the Proposcd Rcstoration Plan (See Figure 8). A bankfull bench or floodplain will also be constructed adjacent to channel aligrunent. The resulting restored stream channel will be approximately 625 linear feet, increasing the overall channel length significantly (roughly 100 fcet). This restoration is considered to be a Priority II restoration and is being utilized in this case because the floodplain at its current elevation is not accessible at bankfull flows. This design is distinguished as a Priority II stream restoration since a bankfull bench (or floodplain) will be constructed adjacent to the proposed channel aligrunent and will be located at a lower elevation relative to the historic or existing floodplain elevation. The existing and proposed morphological characteristics are depicted in the Design Summary Data Table in Appendix E along with Reference Reach and Regional Curve data. The restoration design will result in a riffle-pool system with proper pattern and profile. The new channel will subsequently be vegetated with transplants (of on-site vegetation), bare-root seedlings, and live stakes. Cross-vanes and ]-hooks will be installed to prevent bank erosion, provide grade control, and to enhance pool form. Due to the increased sinuosity and therefore increased length of the restored channel, it will need to be stepped down to tie into the existing culvert downstream ofthe restored reach. The nccessary drop was divided between a steeper section at the beginning of the restored reach, and another at the end of the restored section. Structures located in these steepcr sections will have an added "step" to allow for a greater drop without excessive scour that would thrcatcn the integrity of the structures. - 15 - I I I I I I I I I I I I I I I I I I I A large rock cross vane will also be installed in Wildcat Branch immediately downstream of the box culverts. The upstream end of the cross vane will be lined with large boulders and rip rap (Class I and 2), undcrlain with nonwoven geotextile and a cushion layer of NCDOT #57 stone. This structure is intend cd to protect the culvcrt foundation through the control of scour downstream of the pipe outlet. A step-pool structure will be installed at the outlct of the perchcd 36-inch culvert at the downstream end ofthe restoration site. This structure will tie into the outlet elevation of the pipe and stcp it down to the elevation of the cross vane and the reach's confluence with Wildcat Branch. Where possible, transplanting of woody vcgetation (from on-site) including root mats will be performed to assist in the stabilization of meander bends Erosion control matting (coir matting), temporary seeding, and live stakes will be utilized to reduce bank crosion immediately following completion of the channel and providc bank stabilization. 2.5.1 Dimcnsion Based on reference reach data, and subsequent Regional Curve confirmation, restored channel riffles will be constructed with a bankfull cross-sectional area of 6.5 square feet. The channel bankfull width will be constructed at 7.7 fcet and the mean depth at 0.85 feet. Riffles will have a maximum depth of 1.5 feet. The proposed dimensions will result in an E channel type. A depiction of the proposed riffle cross-section is shown in Figure 10. Pools will be constructed with a maximum depth of3.5 feet and bankfull width of 10.3 feet. The mean pool depth will be 1.7 feet. A depiction of the proposed pool cross-section is also shown in Figure 10. A minimum entrenchment ratio (floodprone area width / bankfull width) of 3.5 will be established along the length of the restored reach. Where possible, based on site constraints, the channel will be constructed with an increased entrenchment ratio. 2.5.2 Pattcrn The current pattern of the existing project reach is essentially straight, with a measured sinuosity of approximately 1.0. Channel pattern will be significantly altered resulting in a substantial increase in sinuosity. The proposed sinuosity as a result of the proposed alignment will be approximately 1.25. See Figure 8. Varying meanders have becn integrated along the length of the restored reach to mimic the variability of a natural channel and utilize the available project area to the maximum extent possible based on cxisting site constraints. Restored radius of curvature will vary from 8 feet to 20 feet and meander wavelength will vary from 30 feet to 52 feet. The integration of meanders into the proposed restoration design reduces overall channel slope by increasing channel length. - 16 - I I I I I I I I I I I I I I I I I I I 2.5.3 Profile The restoration design incorporates riffles, runs, pools, and glides into the longitudinal profile providing bed form characteristics observed within the reference reach. Riffles will be located along straight segments ofthc channel, runs connect the riffles to the pools which are located along the outside meander bcnds, and glides conncct the pool to thc next successivc riffle. An avcrage pool to pool spacing of 25 feet has been incorporated based on reference conditions. As described previously, the overall vertical drop from upstream to downstream on thc project site is slightly over 4 feet. In order to construct a more desirable slope, a portion of this drop (approximately 1.25 feet) will be distributed over grade control (step-pool) structures at the upstream and downstream ends of the site (approximately 0.65 feet at each). This will allow for a desirable average channel slope of 0.45 percent (0.0045 ft. 1ft.) to be constructed along the channel length. The proposed longitudinal profile (with structure type, location, and invert elevation) is depicted on Figurc 9. The as-built profile may differ slightly based on unforeseen site constraints or limitations that may be discovered during construction. 2.6 Stream Structures In order to providc grade control for the restorcd reach, rock and log cross-vanes and j- hooks (with or without steps), have been integrated with the design and will be utilized to reinforce and stabilize thc proposed channel. All structures will be constructed out of natural matcrials typically consisting of locally quarried boulders or logs. Cross-vane and J-Hooks arc in-stream grade control structures that concentrate strcam energy toward the center of the channel and away from the near-bank areas. In doing so, the structure reduces shear stress along the banks and prevents bank erosion. These structures serve as grade control within the bed of the channel and reduce the potential of headcutting, create a stable width/depth ratio, while promoting sediment transport capacity. The upstream side of these structures will be lined with a non-woven fabric and backfilled with excavated channel material and in some cases importcd stone aggregate to improve stability and reducc the potential for piping. Where a larger drop in elevation is needed, a step may be added to either a cross vane or j-hook, and this step will also be lined with a non-woven fabric on the upstream end. Some of the structures depicted in Figure 8 may bc omitted or relocated during construction. Typical structurc details, based on Rosgen designs, are provided on Figures 11 and 12 (Rosgen 2001). - 17 - ,I I I I I I I I I I I I I I I I I I I 2.7 Riparian Buffer Planting A riparian buffer area will be established immediately adjacent to the restored stream channel. The riparian zone will include the entire floodplain and toe slope, which will tie the surrounding existing topography with the proposed bankfull bench elevation. Buffer width to either side of the restored channel will vary based on site constraints; however, a minimum of 30 feet is desired. A 50 feet buffer will be achieved where possible. These areas will be seeded and planted with the appropriate native riparian vegetation and will provide channel stability and treatment of surface waters traveling laterally through the buffer. Species will consist primarily of native trees and shrubs. A significant portion of the riparian zone along the west side of the restored reach will be located within the permanent sewer line easements. The sewer easement is currently vegetated with various herbaceous species. Depending on the extent of the disturbance along the easement due to construction activities, these areas may require replanting. If necessary disturbed portions of the easement will be re-vegetated with transplanted sod mats consisting of native herbaceous plants that will not be adversely affected by annual mowing. Riparian zones outside of the maintained corridors will be planted with bare root seedlings consisting of bottomland hardwood species. Native trees and shrubs that are currently located along the current channel clcaring and excavation limits will bc rcmoved with as much of the root ball intact and transplanted adjacent to the restored stream channel or within the new floodplain. Following the complction of the stream channel, the bare root seedlings will be planted during the fall or early spring seasons to maximize the survivability of planted individuals. During the following fall, supplemental shrub and tree species will be planted if survival rates of previously planted seedlings are below target densities as determined in late summer (August-September). The restored stream channel will be planted with the appropriate channel bank spccies in the fonn oflive stakcs, bare-root seedlings, and transplants consisting primarily of black willow (Salix nigra), silky dogwood (Camus amomum), and elderbcrry (Sambucus canadensis). If quantities from on site sources are not plcntiful, the live stakes will be supplcmcnted by locally identified plant sources or purchased from local, reputable nurseries. Tree and shrub species will be obtained from nearby reputable nurseries if possible. Other sources, outsidc ofthe local area, may be used dcpcnding on the availability of plant material. Trce species individuals will be planted randomly at an 8 ft. by 8 ft. spacing in order to cnsure a desircd planting density of 680 stems per acre outsidc of the existing sewer right-of-way. This will incrcase the potential for the desired 5-year survivability density of at least 260 stems per acre. Shrub species will be planted at a higher density and closer spacing (6 ft. by 6 ft.) to achieve a desired planting density of approximately 1,200 shrubs per acre here again - 18 - I I I I I I I I I I I I I I I I I I I improving the potential for the desired 5-year survivability. Pleasc rcfer to Figure 14 for details of the proposed riparian planting. The planting plan consists of at a minimum, five of the tree species and three of the shrubs listed in the tables below.

A representative of Soil & Environmental Consultants, P A, will bc on site to observc and direct planting efforts associated with the buffer restoration. 2.8 Stream Monitoring Thc project will bc monitored for five consecutive years or until the required success criteria has been met as determined by NC DWQ and the USACE. Monitoring activities will initiatc immediately following the complction of the strcam construction in order to alleviate any potential problems as they occur. Success criteria for stream stability will be met if; for the period of five years in conjunction with vegetation and biological success, the stream bedform features and cross-sections remain stable (i.e. the stream retains its restored Rosgen stream-type classification). During the monitoring period, no less than three bankfull flow events must be documented. Ifless than three bankfull events occur during the monitoring period, monitoring will continue until three bankfull events arc documented. The bankfull events must occur during separate monitoring years. Parameters that will be included in the annual stream monitoring to ensure the success of thc restoration activities will includc stream channel surveys (longitudinal and cross- sectional profiles), pebblc counts, photographs, plant density, diversity and survival inventories, and qualitative benthos sampling. This section includes information concerning; I) thc proposed monitoring plan, 2) biological monitoring, and 3) vegctative monitoring. 2.8.1 Monitoring Plan We proposc that stream monitoring be performed as follows: 1. The monitoring period for the stream is fivc (5) years. 2. Perform onc (1) annual site visit during thc growing season during which thc restored rcach will be observed and evaluated. In Wake County, NC, the growing scason is generally between early March and October. 3. Physical, biological, and vegetative cvaluation of the restored reach will bc performed during thc annual sitc visit. 4. Maintain photographic records of the restored reach with photos taken during each sitc visit. Locate photo points at key locations on stream reach including but not limited to, permanent cross-section locations. - 20- I I I I I I I I I I I I I I I I I I I 5. Submit annual monitoring report to both Agencies at the end of each calendar ycar. The monitoring report will summarize the general site conditions, the results of physical, biological, and vegetativc monitoring, and any recommendations for necessary maintenance. 2.8.2 Physical Monitoring An as-built engineering survey of the site will be conducted upon completion of thc site restoration work to ensure that site grading work was performed in a manncr consistent with the restoration plan. This survey will include a longitudinal profile of the restored reach as well as a minimum of four (4) permanent cross-sections (two riffles and two pools) along the reach. We propose that the annual physical monitoring plan be performed as follows: I. Perform by Total Station a longitudinal profile for comparison with the as-built survey data and subsequent annual surveys. 2. Perform by Total Station a cross-section survey at each pennanent cross- section location for comparison with the as-built survey data and subsequent annual surveys. Photographs of each cross-section will be taken during annual surveys. 3. The reach will be walked and observed for indications of deterioration or failure of any components (crosion, structures, etc.) of the restoration. 2.8.3 Biological Monitoring We propose that the success of the biological component be evaluated using a qualitative evaluation. In this evaluation the length of the restoration rcach we will observe and record benthic macro-invertebrate species during our annual site visits. A similar evaluation will be performed in the adjacent (upstream) reach. Spccies and number will be comparcd to provide an opinion of the biological hcalth of the restored channel relative to the reference reach. 2.8.4 V cgctativc Monitoring We propose that the vcgetative success monitoring be performed as follows: 1. A total of two (2) vegetation monitoring plots will be installed and monitored in the restored buffer to evaluate thc success of plantcd riparian speCIes. 2. Vegetative monitoring plots will be 10m x 10m square will be established in the riparian zones for vegetative monitoring. This size is in keeping with the current monitoring standards used on other restoration sites. - 21 - I I I I I I I I I I I I I I I I I I I 3. Monitoring plots will evaluate the success of tree and shrub species within a given plot. 4. A vegetative success criterion of260 stems per acre will be required at the cnd of the five (5) year monitoring period for forest and woody shrub planting plots. 5. A vegetative success critcrion of 50% coverage will be required at the end of the five (5) year period for the live stakes installed in channel banks. Following thc submittal of the monitoring rcports to the Agency represcntatives, the rccipicnts of the report will be contacted for the purpose of discussing the monitoring data, required success criteria and whether or not the site is functioning as expected. If the site is not functioning as expccted a site visit will be schedulcd with the review agcncics so that a remediation plan can be crcated and implemented. The remediation plans, if required, will dircctly reflect the requested alterations suggested by thc regulatory agencies. - 22- I I I I I I I I I I I I I I I I I I I 3.0 SITE \VETLAND RESTORATION The purpose of this section is to summarize our analyses of the impacted wetland arc a and provide a Conceptual Plan for its restoration and integration with the stream restoration plan. This section includes information conccrning; I) Existing Wetland Conditions, 2) Reference \Vetland Conditions, 3) Wetland Creation, and 4) Wetland Monitoring. 3.1 Existing Wetland Conditions In January 2003, a detailed wctland delineation was pcrformed by Soil & Environmental Consultants, P A, during which we examined and evaluatcd site soils, vegctation, and hydrology of sclect areas by procedures dcscribcd in the 1987 Corps ofEnginecrs Wetland Delineation Manual. Areas on the site with positivc indicators of hydric soils and evidence of wetland hydrology and hydrophytic vegetation were flaggcd with scqucntially numbcrcd. Proof ofwctland hydrology would be the existcnce of hydric soils with oxidized root chmmels in the upper 12 inches of the "A" horizon, water borne dcposits, drift lincs, scour marks, drainage patterns, rcgional indicators of soil saturation, ctc. This delineation was surveycd by Smith and Smith Surveyors and a wetland map was prcpared. This delincation was later revicwcd and approvcd by USACE. A copy of the approved delineation is providcd in Appendix F. As des crib cd previously a total of 0.133 acrcs or 5,812 square fect of jurisdictional wctlands will be impacted through the placcment of fill associated with roadway construction from the widening of Hammond Road. In order to meet Agcncy preferenccs for on sitc restoration of similar wetlands we are proposing the integration of constructed riparian wetlands immediately adjacent to the restored channel within the newly established floodplain area. 3.2 Reference Wetland Conditions In order to facilitatc restoration plan developmcnt as well as streamline restoration efforts we used the existing site wctland (to be impacted) as a template for rcfercnce conditions. In this process we evaluatcd reference for both surface elevation (and subsequent proximity to the adjacent channel invert) and vegetation. And, while other wetland pockcts have becn delineated on site, these areas are relatively small in size and do not appear to be drivcn by the adjacent stream (dircctly or through overbank flooding). These smaller areas do not, in our opinion, reprcsent a refcrence condition to which thc creation of the proposcd wetlands should be pcrfonned. Based on our observation and invcstigation during field visits it was determined that the two factors governing wetland hydrology was pcriodic ovcr bank flooding events and surface elevation relative to ground water (or indicators of ground watcr). The wetland - 23 - I I I I I I I I I I I I I I I I I I I area was qualitatively assessed for vegetative conditions. However, based on the disturbed condition of the site and the poor condition of the existing vegetative community, it is our opinion that it would be suitable to construct a vegetative community (trees, shrubs, and herbaceous) and structure similar to that of a Bottomland Hardwood Forest as described in the NCDENR Field Guide to North Carolina Wetlands (Report 96-0 I). 3.3 \V ctIand Creation Wetland creation will be performed through the conduct of localized grading of the ground surface (within the new floodplain), the transfer of existing wetland soils, and the planting of appropriate native vegetative species. Please refer to Figures 13 and 14 for further details on the proposed construction. 3.3.1 Grading Operations At the northern end of the construction site, a significant surface area within the newly constructed floodplain wiII be available (east and west) of the restored stream for use in the construction of riparian wetlands. Once thc floodplain is graded, a scries ofwctland cells wiII be excavated within the floodplain. The exact depth of these cclls will be dctermined during final design. The relative depth shown on the cross-section is approximate and may vary depending on local topography and conditions observed in the field at the time of construction. These cells, roughly 12 to IS-inches in depth, wiII be backfilled with materials excavated from within the impacted wetland area. The transfer of material wiII serve to "jump start" created wetlands through the placement of hydric soils, in addition to the relocation of a seed source for wetland plant species. The surface of these wetland pockets will be fine-graded to provide micro-topographic variation within the created wetland areas. A representative of Soil & Environmental Consultants, P A, wiII be on site to observe and direct grading efforts associated with the restoration and make adjustments as deemed necessary. 3.3.2 Planting Operations Once appropriate grading is performed, exposed areas within the created wetland pockets wiII be planted with the bare-root seedlings of tree and shrub species listed in the previous tables. Others may be substituted upon approval of the designer depending upon availability. Wetland tree and shrub species wiII be planted at a similar density as previously described in this report to achieve the desired survivability. Tree and shrub species will be generally intermixed, however, zonal densities of select species may occur based on grading conditions, standing water bodies (or those likely to hold standing water during wetter periods) or other factors observed on site. - 24- I I I I I I I I I I I I I I I I I I I Herbaceous species such as Soft Rush (Juncus effusus), Woolgrass (Scirpus cyperinus), Sedges (Carex sp.), and Lizard's Tail (Saururus cernuus) will be used to over-plant portions of restored wetland areas. This, in conjunction with native seed sources, will allow for a dense stand of herbaceous growth. Details of herbaceous species planting will bc described in the construction drawings. Herc again, temporary andlor permanent seeding measurcs (brown top millet, rye grass, or the most appropriate crosion control grass as dictated by the season) will be applied to areas disturbed during grading operations to allow for localized stabilization while wetland species cstablish themselves. A representative of Soil & Environmental Consultants, P A, wiII be on site to observe and direct wetland planting efforts associated with thc restoration. 3.4 Wetland lVlonitoring The success of the restored wetland areas will be based on thc restoration of hydrology within 12 inches of the ground surface and the survival of canopy tree, understory shrub, and herbaceous species for a five year monitoring period. Sample vegetative success plots will be established in the restored areas for vegetative monitoring. All monitoring will occur within these observation plots throughout the monitoring period as long as thcy continue to be reprcsentative of the community. This section includes information conccrning; I) thc proposed monitoring plan, 2) hydrologic monitoring, and 3) vcgetative monitoring. 3.4.1 Monitoring Plan We propose that wetland monitoring bc perfonned as follows: 1. The monitoring period for the constructed wetlands is five (5) years. 2. Perform onc (I) annual site visit (in conjunction with thc stream monitoring) during the growing season during which the wctlands will bc observed and cvaluated. In Wake County, NC, thc growing scason is generally between early March and October. 3. Hydrologic and vegetative evaluation of the created wetlands will be performed during the annual site visit. 4. Maintain photographic records of the wetland with photos taken during each site visit. Locate photo points at key locations. - 25 - 'I I I I I I I I I I I I I I I I I I I 5. Include annual monitoring details as part of the stream monitoring report to both Agencies at the end of each calendar year. The wetland portion of the report will summarize the general site conditions, the results of hydrologic and vegetative monitoring, and any recommendations for necessary maintenance. 3.4.2 Hydrologic Monitoring We propose that the hydrologic site monitoring be perfonned as follows: 1. Locate, via Total Station, an approximate boundary of restored wetlands. 2. Hydrology will be monitored during annual site visit. Hydrologic monitoring will bc by visual observation and with soil evaluation. Hydrology will be monitorcd based on soil characteristics (hydric soils indicators) observed using shallow hand augcr borings. 3.4.3 Vegetative Monitoring We propose that the vegetative success monitoring be performed as follows: 1. A total of two (2) vegetation monitoring plots will be installed and monitored on the restored wetlands. 2. Vegetative monitoring plots will be 10m x 10m square. This size is in keeping with the current monitoring standards used on other rcstoration sites. 3. Monitoring plots will evaluate the success oftrec, shrub, and herbaceous species within a given plot. 4. A vegetative success criterion of260 stems per acre will be required at the end of the five (5) year monitoring period for forest and woody shrub planting plots. 5. Vegetative success criterion of 50% coverage will be required at the end of the five (5) year period for the herbaceous species. In conjunction with the Agency review of the report, if the wetland is not functioning as expected a site visit will be scheduled with the review agencies so that a remediation plan can be created and implemented. The remediation plans, if required, will directly reflect the requested alterations suggested by the regulatory agencies. - 26- I I I I I I I I I I I I I I I I I I I 4.0 LIl\'IITATIONS Our evaluations, conclusions, and recommendations arc based on project and site information available to us at the time of our analysis and may require modification if there are any changes in the sitc conditions, or if additional data about the site becomes availablc in the future. Additionally, dccisions regarding any outstanding permit issues or policies issued by governing regulatory agencies are beyond our control, and as such modifications to our evaluation, conclusions, and/or rccommendations may be necessary. Additional data may become available during futurc dcsign and construction as site and projcct conditions are further invcstigatcd or exposcd by construction.

Bell, III Post Office Box 17274 Raleigh, NC 27619-7274 Subject Property: Hammond Street Road Widening Project, Raleigh, NC Wildcat Branch [03-04-02, 27-34-7, C NSW] NOTICE OF WITHDRAWL Dear Mr. Bell: On January 4, 2005, you requested a 401 Water Quality Certification from the Division of Water Quality (DWQ) for your project. We wrote to you on January 18, 2005 discussing concerns that we have regarding the design of the project and stating that it would be placed on hold for three weeks giving you time to address DWQ's concerns. As of today, DWQ has not received a response to this request. Therefore, your file is hereby considered withdrawn and will not be reviewed until DWQ's earlier concerns are addressed. Once you have collected sufficient information to have a complete application (please see our January 18, 2005 letter for the missing information), you will need to reapply for DWQ approval. This includes submitting a complete application package with the appropriate fee.
