HomeMy WebLinkAbout20231428 Ver 1_Whispering_Branch_Attachment_A_Combined_20231017Attachment A Proposed Bank Stabilization 3806 Whispering Branch Road, Raleigh The purpose of this project is to stabilize and repair a streambank which has failed and exposed a previously buried gravity sewer pipe. An exposed gravity sewer ductile iron pipe has become uncovered in the streambed due to high velocity flows and will remain exposed in the stream bed. The project will temporarily impact a total of approximately 40 linear feet of stream length during dewatering and will permanently impacts approximately 20 linear feet of streambank via riprap and coir fiber matting stabilization impacts. Total length of stream impacts is 40 linear feet due to overlapping dewatering and bank stabilization impacts. These impacts will occur on UT to Hare Snipe Creek near 3806 Whispering Branch Road at 3S.892960,-78.704228 decimal degrees. Work will entail creating a dry work area, establishing a stable toe, constructing a stable bank using coir matting or rip -rap or a combination and establishing a stable segment of stream bed at the base of the bank. Rip rap will be installed if 2:1 slope can be achieved and geo soil lifts or similar construction will be employed if slopes must be greater than 2:1. The existing concrete collar on the sanitary sewer will be removed. Restraints will be added to exposed joints. The site will be accessed from the existing sanitary sewer easement from Whispering Branch Road. The temporary disturbance will occur inside the maintained easement. There will be no tree removal as the easement has been maintained as herbaceous. Erosion control measures will be installed prior to work. A "pump around" will be established to create a dry work area. Disturbed area will be reseeded and mulched when work is complete. It is expected that a tire or track -mounted excavator and a dump truck will be used to place the boulders, reconstruct the streambank, and stabilize the streambank. Please see the eight attached details: "pump around", temporary silt fence, temporary construction entrance, stream crossing, bank stabilization, geo soil lifts, restraint joint, and seeding details. �h":111IOl� 0 ►siilic�.1/�T�.`� 1��6�d �,1�- �� 1�I�Lfl�flll� ►`�I�' .`_„_: UT to Hare Snipe Creek 3806 Whispering Branch Road 35.892960,-78.704228 78043'43.39"W 35055'26.4"N k 91 +�li"t f�`i •Y k i {,+j IL • JA E M.

Rev. 5/08 6.11.19 9/14/23, 2:10 PM IPaC: Explore Location resources IPaC U.S. Fish & Wildlife Service IPaC resource list This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site -specific (e.g., vegetation/species VW4 surveys) and project -specific (e.g., magnitude and timing of proposed activities) information. Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site -specific and project -specific information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly. For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following: 1.

Probability of Presence Summary BREEDING SEASON Breeds Sep 1 to jul 31 The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report. Probability of Presence ( ) https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 6/16 9/14/23, 2:10 PM IPaC: Explore Location resources Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4- week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. rw 0 To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season () * nN.011— Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort (1) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. To see a bar's survey effort range, simply hover your mouse cursor over the bar. No Data (—) A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse. probability of presence breeding season I survey effort — no data https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 7/16 9/14/23, 2:10 PM IPaC: Explore Location resources SPECIES JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Non -BCC C too$ 0+01000010111' +0*+ 11 I I ++*0 Vulnerable What does IPaC use to generate the potential presence of bald and golden eagles in my specified location?

The number of surveys is expressed as a range, for example, 33 to 64 surveys. To see a bar's survey effort range, simply hover your mouse cursor over the bar. No Data (—) A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse. probability of presence breeding season I survey effort — no data https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 11/16 9/14/23, 2:10 PM IPaC: Explore Location resources SPECIES JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Bald Eagle I I I'$ J+01 I$$$ ICI I I' +$T+ III I 11 1 1 ��TT III T11� 1 Non -BCC Vulnerable Black -billed ++++ TTTT TTTT TTTT Cuckoo BCC Rangewide (CON) Chimney Swift +++ TTTT BCC Rangewide TTTT �111 111� Toll 1111 I I+ I 114 ++++ (CON) Eastern Whip- __ _ I l l I yy1 y I++ I II 111�I poor -will I _I _I I I _I__I__I- +TTT TTTT ++IIIIII 111* j + T+++ TTTT -f -�+ +++-I I-+++ TTT+ BCC Rangewide (CON) ti Kentucky ++++ ++++ ++++ Al FI I I I I I � � I � �► I I I I- I I I I I 11- 14 1-1I ++ + Warbler BCC Rangewide (CON) Prairie Warbler + I ++ ++++ ++++ +$11 Jill Jill I + +l 4] 4 +++ ++++ ++++ BCC Rangewide (CON) Prothonotary ++++ ++++ +++ I III I I I I I IIII 11 1 1 ++++ ++++ ++++ ++++ ++++ Warbler BCC Rangewide - (CON) Red-headed + I I it ++++ +4 ++ + I I t rl 1 111I11U1U 11 1111 IIII-10014 +Ih++ ++++ + I I i Woodpecker BCC Rangewide (CON) I I 11 I ITT I I TT++ I yy Rusty Blackbird + ++++ ++++ ++++ TT ++++ ++++ ++++ ++++ ++T+ ++++ BCC - BCR BWood Thrush CC Rangewide ++++ ++++ ++++ T41 dII IF 1"' !Ili I I � T+so ++tt ++++ ++++ (CON) Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 12/16 9/14/23, 2:10 PM IPaC: Explore Location resources What does IPaC use to generate the list of migratory birds that potentially occur in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey., banding, and citizen science datasets. X N Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering or migrating in my area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may query your location using the RAIL Tool and look at the range maps provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 13/16 9/14/23, 2:10 PM IPaC: Explore Location resources Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. 1 No 4k Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page. https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 14/16 9/14/23, 2:10 PM IPaC: Explore Location resources Facilities National Wildlife Refuge lands Any activity proposed on lands managed by the National Wildlife Refuge system must undergo a 'Compatibility Determination' conducted by the Refuge.

Wetlands in the National Wetlands Inventory (NWI) _G, ( )v Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes. For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District. Please note that the NWI data being shown may be out of date. We are currently working to update our NWI data set. We recommend you verify these results with a site visit to determine the actual extent of wetlands on site. This location overlaps the following wetlands: FRESHWATER FORESTED/SHRUB WETLAND PF01A A full description for each wetland code can be found at the National Wetlands Inventory_ website https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 15/16 9/14/23, 2:10 PM IPaC: Explore Location resources NOTE: This initial screening does not replace an on -site delineation to determine whether wetlands occur. Additional information on the NWI data is provided below. Data limitations The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the Imagery or fieldwork. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. 00 Data exclusions' Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. I k k Data precautions "- Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities. https://ipac.ecosphere.fws.gov/location/PDVLUINKTRH3FI35JLPHRHPAG4/resources 16/16 Roy Cooper, Governor �00■0 INC DEPARTMENT OF ■ ■ ■■u■■ NATURAL AND CULTURAL RESOURCES ■ ■■■ Jessica Tisdale HDR 555 Fayetteville Street Raleigh, NC 27601 RE: 3806 Whispering Branch Dear Jessica Tisdale: September 14, 2023 Rd City of Raleigh Sanitary Sewer Repair D. Reid Wilson, Secretary Micky Buchanan Deputy Director, Natural Heritage Program NCNHDE-23332 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. A query of the NCNHP database indicates that there are records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. These results are presented in the attached 'Documented Occurrences' tables and map. The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is documented within the project area or indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: https://www.fws.gov/offices/Di rectory_/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission.
