-4� WithersRavenel 1/ Our People. Your Success. June 26, 2019 US Army Corps of Engineers Raleigh Regulatory Field Office Ms. Samantha Dailey 3331 Heritage Trade Drive Suite 105 Wake Forest, NC 27587 NC -Division of Water Resources 401 & Buffer Permitting Unit Ms. Karen Higgins 1617 Mail Service Center Raleigh, NC 27699 Re: Town of Knightdale Environmental Park - NWP 3 & 18 PCN Submittal Knightdale, Wake County WR Project #02180515.02 Dear Ms. Dailey and Ms. Higgins, On behalf of the Town of Knightdale, we are requesting authorization from the USACE to use NWP 3 for 0.973 acres of temporary open water impacts and 34 If of permanent stream impacts for pond maintenance and NWP 18 for 0.019 acres of permanent wetland impacts and 33 If of permanent stream impacts for construction of a plunge pool below the culvert in N. Smithfield Road. We are also requesting a 401 WQC from NCDWR for the above referenced impacts, as well as a Neuse River Riparian Buffer Authorization for 5,755 sf of permanent riparian buffer impacts and 6,559 sf of temporary riparian buffer impacts. The proposed project is located within the ±7.94 acre Town of Knightdale Environmental Park (PIN: 1754188334), which is located west of the intersection of N. Smithfield Rd and Edenburghs Keep Dr in Knightdale, Wake County. The project is located in the Neuse River basin (HUC: 03020201) and the site drains to Beaverdam Creek (Stream Index: 27-29; Water Classification: C;NSW). Proposed Proiect The purpose of the proposed project is to improve the overall water quality and aquatic habitat within the onsite perennial stream and onsite pond, and ultimately Beaverdam Creek, by reducing the amount of sediment being transported into the onsite stream and pond. Additionally, the project will improve water quality and enhance the aquatic habitat within the pond. Furthermore, the proposed dredging will increase the storage capacity of the pond, thereby helping to alleviate flooding issues upstream caused by the current shallow water depths due to sediment deposition. This will be accomplished by removing the accumulated sediment to increase water depths and create areas of various depths in order to establish aquatic habitat zones of varying depths in order to provide habitat for the many stages of the life cycle of the aquatic fauna that inhabits the lake. The onsite perennial stream (UT to Beaverdam Creek) originates as a culvert discharging runoff from Hwy 64, and receives urban runoff from the surrounding commercial and residential development. During a storm event, the stream experiences flash flooding, causing significant erosion of the stream banks upstream of the project. This causes extreme silt and sediment 219 Station Road, Suite 1011 Wilmington, NC 28405 t: 910.256.9277 www.withersravenel.com I License No. C-0832 Asheville I Cary Greensboro I Pittsboro I Raleigh I Wilmington Town of Knightdale Environmental Park - Knightdale, Wake Co. %0 Withers Rave n e l Jnr Pcnolc Ycur Success. loading, which ultimately suspends out within the perennial stream and pond as flow velocity decreases in the headwaters of the pond. The sediment deposition within the onsite pond has resulted in a loss of approximately 0.4 acres of open water surface area in the head of the pond since 1988, reducing the pond size from ±1.5 acres in 1988 to ±1.1 acres currently. The ±0.43 acres of previous open water that has silted in has converted to forested wetlands, which will not be disturbed during dredging of the pond. The sediment deposition within the pond has reduced the average water depth to only ±4.0 feet at the dam to only a few inches near the observation deck. The historic depths ranged from ±8 ft near the dam to 1-3 ft near the observation deck. The shallow water depth has created poor water quality, higher water temperatures in the summer due to solar heating and low dissolved oxygen levels, resulting in algal blooms. The proposed project will aid in alleviating the sediment transport into the onsite stream and pond by constructing a plunge pool downstream of the existing culvert beneath N. Smithfield Rd. Sediment deposition is so bad following a storm event that the culvert becomes blocked, causing flooding in the neighborhoods upstream. The Town has to use an excavator to remove enough sediment below the culvert to restore flow and allow flooding to subside. The proposed plunge pool will reduce flow velocity to allow sediment to suspend out prior to entering the pond, and will provide a means for removal of accumulated sediment. The plunge pool has been designed to have a concrete lined bottom, which will make removal of accumulated sediment easier. Access for construction of the plunge pool and regular maintenance/sediment removal will occur from an existing maintenance road off of N. Smithfield Rd. The proposed lake dredging will restore the pond to historic water depths. During the onsite pre - application meeting on 5/13/19, Samantha Dailey with the USACE determined that dredging of the pond would be allowed up to the existing woody vegetation line, as depicted in the attached Impact Maps. The water level of the pond will be pumped down and temporary coffer dams will be installed upstream of the pond and flow will be pumped around the pond and downstream of the dam to create a dry pond bed. Excavators will be used to remove accumulated sediment and restore historic water depths. During sediment removal, double handling of spoil will be minimized to the greatest extent possible. All spoil will be loaded in dump trucks and hauled to an offsite upland disposal area. Construction access for the sediment removal within the pond and hauling of spoil will occur within an existing sewer easement running south from the pond to the existing access road for the pump station which will provide access to N. Smithfield Rd. After the sediment removal is complete, the existing outlet structure will be replaced. As part of the replacement of the outlet structure, approximately 34 If of stream channel will be lined with rip -rap to create a dissipater. The project will be constructed using traditional commercial construction equipment and techniques. Proiect History Samantha Dailey with the USACE conducted an onsite pre -application meeting on 5/13/19 to review the project area and discuss the proposed activities. Page 2 of 4 Town of Knightdale Environmental Park - Knightdale, Wake Co. %0 Withers Rave n e l n,�r Pcoolc Your s.,«ess. WithersRavenel conducted a delineation of the onsite wetlands and streams in May 2019. We are not requesting issuance of a Jurisdictional Determination in conjunction with issuance of the requested NWPs. The features depicted on the USGS and Wake County Soil Survey were present in the field. Therefore, subjectivity to Neuse River Riparian Buffers is conceded, and a formal Buffer Determination from NCDWR was not requested. Proposed Impacts The proposed impacts consist of: Impacts for Pond Maintenance (NWP 3) • 0.973 acres of temporary open water impacts (Impact 4) • 34 If of permanent stream impacts (Impact 3) (rip -rap dissipater below new outfall) • 4,946 sf of permanent riparian buffer impacts for replacement of pond outfall structure (Impact 8) • 6,268 sf of temporary riparian buffer impacts (Impacts 7 & 9) (for construction access) The construction access will occur from an existing maintenance road within the buffers which has a vegetative cover of mowed grass. Once construction is complete, the vegetation within the temporary buffer impact area will be restored by planting grass seed to restore the existing vegetative cover. Impacts for Plunge Pool Construction (NWP 18) • 0.019 acres (828 sf) of permanent wetland impacts (Impact 1) • 33 If (438 A of permanent stream impacts (Impact 2) • Please note that total permanent wetland/stream impacts for construction of plunge pool are less than 0.10 acres, making it eligible for authorization under a NWP 18. • 809 sf of permanent riparian buffer impacts (Impact 5) (for construction of plunge pool) • 318 sf of temporary riparian buffer impacts (Impact 6) (for construction access) The construction access for the pond dredging will occur within an existing cleared, maintained sewer easement, which has a vegetative cover of mowed grass. Once construction is complete, the vegetation within the temporary buffer impact area will be restored by planting grass seed to restore the existing vegetative cover. Avoidance and Minimization Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and "waters" could be minimized. Due to the nature of the project, impacts could not be avoided. Impacts have been minimized to only those necessary to for construction of the plunge pool and sediment removal within the pond to improve water quality and aquatic habitat within the project area. Page 3 of 4 Town of Knightdale Environmental Park - Knightdale, Wake Co. %/ Withers Rave n e l n,�r Pcoolc Your s.,«ess. Impacts have also been minimized by designing the project to access the project areas via existing roads, trails and uplands. Additionally, sediment removal within the lake will occur "in the dry" to prevent the escape of sediment and turbid water into downstream waters. Mitigation The proposed permanent stream impacts are less than 150 If, and permanent wetland impacts are less than 0.10 acres. Therefore mitigation is not proposed. The current request is for 0.019 acres of permanent wetland impacts, 74 If of permanent stream impacts, 0.973 acres of temporary open water impacts, 5,755 sf of permanent riparian buffer impacts and 6,559 sf of temporary riparian buffer impacts (see the attached maps and PCN for details).

Does this project involve (1) blasting, and/or (2) other percussive activities that will be conducted by machines, such as jackhammers, mechanized pile drivers, etc.? r Yes r No 5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? WR reviewed the NC Natural Heritage Program database, located at http://www.ncnhp.org/web/nhp/home, as well as NCNHP GIS data to identify if there were any known occurrences of endangered species on or near the proposed project. The review of the NHP data did not identify any recent occurrences of federally listed threatened or endangered species or critical habitat on the subject property or within 1.0 miles of the project, see attached NCNHP project review letter. Site reviews did not identify any potential habitat for bald eagle, red -cockaded woodpecker or Michauxs sumac. The project is located in the Neuse River Basin, and therefore is not located within the known range of the Cape Fear Shiner. Additionally, the project is not located within the known range of the Tar River spinymussel and yellow lance. The project site is within the known range of the Carolina madtom, Neuse River waterdog, Atlantic pigtoe and dwarf wedgemussel. The onsite perennial stream is an urban stream, fed primarily by runoff from Hwy 64 and surrounding commercial and residential development. As a result of the urban runoff, the stream is subject to flash flooding, which causes high silt and sediment loading and deposition due to the erosion of the banks. The onsite perennial stream does not have the excellent water quality and high oxygen levels necessary to be considered potential habitat for these species. Additionally, the onsite perennial stream is located upstream of five separate dammed impoundments upstream of the Neuse River, including Nueseoco Lake and Beaverdam Lake, which would prevent migration of these species to sustain viable populations. Therefore, the onsite perennial stream was not considered potential habitat for the Carolina madtom, Neuse River waterdog, Atlantic pigtoe and dwarf wedgemussel. Therefore, the proposed project will have No Effect on federally listed species. Consultation Documentation Upload NCNHP Project Review Letter_ 2019-06-25.pdf 224.08KB 6. Essential Fish Habitat (Corps Requirement) 6a. Will this project occur in or near an area designated as an Essential Fish Habitat?* r Yes r No 6b. What data sources did you use to determine whether your site would impact an Essential Fish Habitat?* There are no waters classified as EFH in Wake County. 7. Historic or Prehistoric Cultural Resources (Corps Requirement) 7a. Will this project occur in or near an area that the state, federal or tribal governments have designated as having historic or cultural preservation status?* r Yes r No 7b. What data sources did you use to determine whether your site would impact historic or archeological resources?* WR reviewed the NC State Historic Preservation Office's online database, located at: http://gis.nrdcr.gov/hpoweb/, to determine if there were any known historic or cultural resources within or in the vicinity of the proposed project. The database review did not identify any known resources within or in the vicinity of the proposed project. 7c. Historic or Prehistoric Information Upload 8. Flood Zone Designation (Corps Requirement) 8a. Will this project occur in a FEMA -designated 100 -year floodplain?* r: Yes r No 8b. If yes, explain how project meets FEMA requirements: The proposed project consists of construction of subsurface plunge pool and sediment removal within the onsite pond, and will not result in above grade fills that will affect the floodplain.

Knightdale Environmental Park, 02180515.02 Dear Troy Beasley. 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/Directory/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. Also please note that the NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or an occurrence of a Federally -listed species is documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodney.butlerLncdcr.gov or 919-707-8603.

Please note, however, that although the NCNHP database does not show records for rare species within the project area, it does not necessarily mean that they are not present, it may simply mean that the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project area contains suitable habitat for rare species. If rare species are found, the NCNHP would appreciate receiving this information so that we may update our database.
