D-1 EXECUTIVE SUMMARY Sage Ecological Services, Inc. (Sage) was retained by Mr. Steven Fuhrman to complete an evaluation of wetlands, streams and riparian buffers on the approximately 1.39-acre parcel (Site) located at 3421 Donnigale Avenue in SW Durham, North Carolina. Property identification number (PIN) 0801-60-85-9056 corresponds to the Site. The purpose of this evaluation was to determine if jurisdictional waters (e.g. wetlands, streams, ponds, etc.) and/or their associated riparian buffers exist on the Site and if so to approximate their limits. Mr. Sean Clark and Mr. Phil Beach, PWS of Sage completed the field evaluation on June 25, 2019. The attached Figure 1 shows the general location of the Site on the applicable SW Durham, INC United States Geological Survey (USGS) topographical quadrangle sheet, and Figure 2 shows the Site's location on the applicable portion (sheet 25) of the United States Department of Agriculture's Natural Resources Conservation Service (USDA NRCS) Soil Survey for Durham. One marginal stream (SA) was identified and flagged on the Site. Portions of SA were found to be both potentially buffered, and jurisdictional. No wetlands were found to be located on the site. The attached Figure 3 shows the approximate location and limits of SA. Field meetings with the US Army Corps of Engineers (USACE) and the City of Durham will be required to verify the limits of the stream / wetland delineation and riparian buffer determination performed by Sage. Any features determined to be jurisdictional should be located by a licensed surveyor in order to produce a survey for the approval as well as for final planning purposes. SECTION 1 REGULATION DEFINITION 1.1 Definition of "Waters of the United States" "Waters of the United States" is a broad term originally defined within the Clean Water Act of 1972, which includes intrastate lakes, rivers, perennial and intermittent streams, mudflats and sand flats, wetlands, sloughs, wet meadows, and ponds, which could affect interstate and foreign commerce. 1.2 Definition of Wetlands Within the 1987 USACE Wetlands Delineation Manual (Environmental Laboratory, 1987) wetlands are defined as follows: Wetlands are "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." Three parameters are used to determine if an area is classifiable as a wetland. These three criteria are hydric soils, hydrology, and vegetation. Positive indicators of all three parameters must be found in order for the area to be considered a wetland. 1. Soils: As currently defined by the USACE, some indicators of hydric soils include a chroma value of 2 or less (i.e. grayish color) in the Munsell Soil Color Chart or a gleyed color, the presence of a sulfidic odor, a high organic content in surface layer of sandy soils, concretions (e.g. manganese), or the listing of the soil series on the national or local hydric soils list. 2. Hydrology: Primary indicators of wetland hydrology include the presence of free water in an excavated pit or saturated soils within the upper twelve inches of the soil, standing water or inundated conditions, sediment deposits, water stained leaves, or oxidized root channels in the upper twelve inches of the soil. Secondary indicators include, but are not limited to, crayfish burrows and drainage patterns. Only one primary hydrology indicator is required in order for an area to contain wetland hydrology, however, two secondary indicators are required if there is no primary indicator present. 2 3. Vegetation: Vegetation commonly found in and adjacent to wetlands are rated based on the percentage of time that each species is found in a wetland or on high ground that is not wetland. Species found almost exclusively in wetlands (99% or more) are considered obligate wetland species (OBL). Species found 67% to 98% of the time in wetlands, are considered facultative wetland (FACW) species and species found in wetlands 34%to 66% of the time are considered facultative species (FAC). Facultative Upland Species (FACU) and Obligate Upland Species (UPL) refer to those species that occur predominately in upland, or non -wetland areas. In order for an evaluated area to meet the hydrophytic vegetation requirement, 50% or greater of the dominant plant species must be FAC or wetter. 1.3 Definition of Streams In general, there are three main stream types that describe overall stream flow. These are ephemeral, intermittent, and perennial. Ephemeral streams only contain water immediately after a large rain event whereas perennial stream channels typically contain water throughout the year. Intermittent streams may contain water during the winter (i.e. during higher water table periods of time) but are usually dry during the summer except after rain events. Streams are assessed and defined locally by the USACE and the NC Division of Water Resources (NCDWR). Each agency has its own assessment form and methodology that is used to describe and define streams. Both forms assign numerical values to different stream characteristics which generally break into the three main categories of Geomorphology, Hydrology, and Biology. The NCDWR currently uses the "NC DWQ Stream Identification Form Version 4.11 " and the USACE currently uses the "Stream Quality Assessment Worksheet." NCDWR's form is also utilized to determine the applicability of riparian buffers on intermittent and perennial streams within the river basins where stream buffers are applied. Currently, ephemeral streams are not buffered by the NCDWR. 1.4 Regulation of Wetlands and Streams Wetlands and streams are USACE regulated "waters of the United States" under Section 404 of the Clean Water Act. Section 404, administered by USACE, requires permits for discharges of dredged or fill material into regulated "waters of the United States." As granted under Section 401 of the Clean Water Act, the state of North Carolina, through the NCDWR, also regulates disturbance activities in wetlands or other waters of the United States in the state of North Carolina. 3 NCDWR also regulates disturbance activities within wetland and stream areas that are "isolated" from waters of the US and are therefore not regulated by the USACE due to their lack of connection to other waters of the US. All areas regulated by NCDWR are considered "waters of the state" and disturbance to these areas are permitted through the 401-permitting process which is separate from the USACE's 404-permitting process. 1.5 Regulation of Riparian Buffers Within the Jordan Lake drainage, the NCDWR regulates a 50-foot riparian buffer that extends landward from each side of surface waters (e.g. streams, lakes, ponds, rivers, etc.). The City of Durham regulates activities within the 50-foot buffer when these areas are within the city's jurisdiction. Drainage features depicted as streams on the most recently published USGS topographical maps and/or the most recently published NRCS soil survey maps are subject to these buffers unless determined otherwise by City of Durham staff. A cumulative score of 19 on the previously mentioned "NC-DWQ Stream Identification Form Version 4.11 " is required in order for the stream to be subject to the rules. A score of less than 19 typically means that the stream is ephemeral and is therefore not subject to the 50-foot buffers. Activities within the buffers fall into the four main categories of exempt, allowable, allowable with mitigation, and prohibited. All activities within the buffers except for those determined to be exempt require prior written approval. 4 SECTION 2 SITE DESCRIPTION 2.1 Site Location The Site is located approximately 300 feet east of the Brecknock Street and Donnigale Avenue intersection in Durham, North Carolina. The coordinates of 35.977055°N, 78.976750°W, generally correspond to the center of the Site. The Site is within the piedmont region of North Carolina and is within the Cape Fear River Basin. 2.2 General Site Description The 1.39 -acre Site is wooded and undeveloped. A canopy of mixed hardwoods, open understory and dense herb layer are present on the Site. The property generally slopes from NE to SW. Soils on the Site are mapped in the Durham County Soil Survey to contain the White Store sandy loam soil series. The topography of the Site ranges from a low point of +/- 300 feet above mean sea level (msl) at the northeastern property corner to a high point of 326 feet msl in in the SW corner of the Site. 5 SECTION 3 SCOPE OF SERVICES 3.1 Performed Scope of Work Sage was contracted to complete an evaluation of wetlands, streams, and riparian buffers on the Site. The methodology for our work is discussed below. 3.2 Wetland Evaluation Methodology The wetland evaluation was completed based upon the procedures specified and described in the "Corps of Engineers Wetlands Delineation Manual" (January 1987 - Final Report) and using the current regional guidance. Prior to arriving on -site, topographical maps, soil survey maps, orthophotographs, and ArcGIS generated maps of the area were reviewed to preliminarily identify areas (e.g. drainages, hydric soils areas, areas showing standing water, etc.) where wetlands would likely exist. The Site was traversed on foot and evaluated for the presence of hydric soils indicators, evidence of wetland hydrology, and existence of hydrophytic vegetation. 3.3 Stream and Riparian Buffer Evaluation Methodology Topographical maps, soil survey maps, and aerial maps of the Site were reviewed in order to preliminarily identify drainages where potential streams may exist. It is important to note that the NRCS web -based soil maps do not indicate drainages and streams. Drainages within the Site were evaluated using the current "NC-DWQ Stream Identification Form (Version 4.1 1)" and/or the USACE's Stream Quality Assessment Worksheet. Both agencies have their own forms, which assign numerical values to different characteristics such as the presence of fish, particle size in the stream versus that of the adjacent upland area, etc. NCDWR's form is used to identify if a drainage is subject to riparian buffers as well as to identify the stream's flow regime (i.e. ephemeral, intermittent, or perennial). The USACE's form does not attempt to define a stream as being intermittent or perennial. The NCDWR's terms and the USACE's terms are not always synonymous and interchangeable. The USACE generally considers a drainage to contain a jurisdictional stream if there is an Ordinary High Water Mark (OHWM) or evidence of periodic concentrated flow. The stream designations from both the USACE and DWR hold more significance in the event that impacts (e.g. road or utility N. crossings or general fill) are required. The NCDWR will require mitigation for impacts to intermittent and perennial streams. The USACE typically requires mitigation for impacts to streams that are "important to aquatic function" and may not require mitigation for impacts to streams that are not as much so. 7 SECTION 4 RESULTS OF EVALUATION 4.1 Wetlands Evaluation The Site was evaluated per the methodology described above for any areas containing the three wetland criteria (hydric soils, wetland hydrology, and hydrophytic vegetation). No areas which met the three parameter criteria were identified on the Site. 4.2 Stream Determinations Stream forms were completed in several locations along Features SA and SB. These were completed in order to determine if any areas met the stream criteria described above in Section 3.3. Stream form locations were flagged in the field and labeled to correspond with the forms attached to this report. Stream Form SFA3 on feature SA scored a 20.5 on the NCDWQ Stream Identification Form within the flagged section between flag SA01 and SA02. This section of SA exhibited a weak presence of differentiated substrate, absent depositional bars / benches, and weak headcuts. The remaining portions of the evaluated SA drainage scored a 4.5 (stream form SFA4) above flag SA01 and a 15.5 and 16.5 at areas down slope from flag SA02. Feature SB, which is not depicted on the USGS or soil survey maps, scored a 16.5 at the top of the evaluated drainage and a 15.75 at a point down slope. This drainage did not exhibit baseflow, contained weak sinuosity, and had poor substrate differentiation. Furthermore, no hydric soils were observed within the drainage. Upon completion of the field assessment it was determined that Feature SA is marginally intermittent, and Feature SB is ephemeral. The table below and Figure 3 provide additional information and a visual description for the feature located on the tract. Table 1. Site Surface Water Summary Feature Id and Latitude Longitude Flow Feature Jurisdictional Buffered Flag Numbers Regime Length SA (SA01-SA02) 35.9771650 N 78.9765240 W Intermittent +/- 100 LF Potentially Potentially The Site ultimately drains to Mud Creek which is classified as a Water Supply V (WS-V; NSW). These classifications are generated by the NC DEQ's "Classifications and Water Quality Standards 0 Applicable to Surface Water and Wetlands of North Carolina." Please note that the jurisdictional status of site drainages needs to be confirmed by the USACE to be valid. 4.3 Riparian Buffer Determinations Stream Feature SA is approximately located on the Soil Survey for Durham County and also exhibited intermittent flow with a score >19 on the NC-DWQ 4.11 within the section between flags SA01 and SA02. Therefore, SA is potentially subject to the NCDWR regulated Jordan Buffer Rules. The drainage above flag SA01 and below flag SA02 is believed to be ephemeral and not subject to the riparian buffers. Feature SB is not depicted on either Soil Survey nor most recent USGS map for Durham County, and also did not exhibit indications of intermittent flow. Therefore, SB is not subject to the NCDWR regulated Jordan Buffer Rules. SA is believed to begin at flag SAO1 which is located in the northern portion of the Site. As previously mentioned, a field determination by Durham staff or NCDWR will be necessary to verify our buffer determinations. 9 SECTION 5 CONCLUSIONS AND RECOMMENDATIONS 5.1 Conclusions and Recommendations The wetland, stream, and riparian buffer evaluation was completed for the 1.39-acre Site on June 25, 2019. Upon completion of the field investigation, map assessment, and literature review, it was determined that a section of marginal potentially jurisdictional and buffered, intermittent stream starts in the northern portion of the property approximately 40 feet west of the eastern property line and flows for +/- 100 feet. Another drainage feature was identified in the field (SB) and determined to not be jurisdictional or subject to riparian buffers. A site meeting with the USACE is recommended prior to the development of the Site in order to confirm the jurisdictional status of Features SA and SB as well as to concur that no wetlands are present on the Site. The field verification may be required in order to obtain a preliminary jurisdictional determination (PJD). It is also recommended that a buffer determination with the City of Durham (NCDWR delegated authority) be conducted to verify our findings as they relate to the subjectivity of riparian buffers on the Site. If development is proposed on the Site, a state buffer authorization, federal permit (for stream impacts), and state water quality certification may be required to develop this Site. Sage is available to assist with preparing the aforementioned documents for submittal and/or to conduct or coordinate any required additional surveys in conjunction with permit. Features determined to be jurisdictional and / or subject to buffers should be located by a licensed surveyor in order to produce a survey for the approval as well as for final planning purposes.
