(S&ME) hereby submits this Pre -construction Notification (PCN) for temporary impacts to waters of the U.S. in accordance with Nationwide Permit (NWP) Nos. 3 (Maintenance ) and 33 (Temporary Construction Access and Dewatering), along with General Water Quality Certification Nos. 4132 and 4141. The project entails performance of work necessary to comply with a Dam Safety Order issued by the North Carolina Department of Environmental Quality (NCDEQ). In support of this application, the following accompanying information has been submitted through the N.C. Division of Water Resources (NCDWR) On-line PCN website (https://edocs.deg.nc.gov/Forms/Pre- Construction Notification Form): Figures: Site Vicinity Exhibit (Figure 1), USGS Topographic Exhibit (Figure 2), and 2016 Aerial Ortho Imagery Exhibit (Figure 3) NCDEQ Dam Safety Order Site Photographs Completed Pre -Construction Notification (PCN) and Agent Authorization Form Interim Dewatering -Repair Plan Drawing NCNHP Database Report S&ME, INC. / 9751 Southern Pine Blvd / Charlotte, NC 28273 / p 704.523.4726 f 704.525.3953 / www.smeinc.com Pre -Construction Notification S&ME Project No. 7335-19-008 Lady Marion Dam April 1, 2019 Because the project area is located in a trout watershed, we understand that a copy of this PCN will also be provided electronically to the NC Wildlife Resources Commission (NCWRC). The project also requires pre -construction written approval from the N.C. Division of Water Resources (NCDWR), but should comply with the relevant conditions of General Water Quality Certification Nos. 4132 / 4141. General Project Information The Lady Marion Dam and its adjacent reservoir are located roughly between US Highway 70 to the east and US Highway 221 to the west in Marion, McDowell County, NC (35.694136°N, -82.025724°W). The location of the project area is depicted on the attached Site Vicinity Exhibit (Figure 1), the appropriate portion of the 1985 Marion West, NC USGS Topographic Map (Figure 2), and a 2016 Aerial Orthoimagery Exhibit (Figure 3). According to the NCDEQ - Energy, Mineral and Land Resources Division, which regulates Dams in North Carolina, the Lady Marion Dam is classified as a small, high hazard (Class C) dam. The dam was reportedly constructed in the late 1960's or early 1970's. The adjacent Westwood Chateau Condominium complex was constructed on the dam and over an associated concrete outlet culvert. The condominiums have experienced structural problems associated with settlement. Based on previous assessments conducted by others, it is believed that internal erosion (piping) and/or deflection of the top of the culvert due to reduced structural support may be factors in the previous settlement and building distress. Existing steel bracing present within the culvert in the vicinity of the condominiums has become deteriorated and appears to have experienced buckling. The NCDEQ issued a Dam Safety Order (MCDOW-010) dated January 25, 2019 requiring preparation of plans to repair, or alternately, breach the Lady Marion Dam. A copy of the Dam Safety Order was included in the accompanying information submitted with the online PCN. In general, the Dam Safety Order required the following: The reservoir shall be immediately drained per the design recommendations and oversight of a professional engineer, at a rate of no more than one foot per day. The reservoir shall be maintained in a totally drained condition until repairs or a plan to permanently breach that plan has been approved and accomplished. The owners shall develop and implement an approved Emergency Action Plan (EAP). Submit plans, specifications and supporting data developed by a professional engineer for repair or breach of the dam and permanent drainage of the reservoir in a manner that precludes downstream sedimentation. Our client has decided to pursue the option of breaching the dam and permanently draining the reservoir. Existing Environment The project area is located near the western edge of the Piedmont Physiographic Province of North Carolina. Topography in the area is generally slopes somewhat steeply towards the reservoir. Review of the 1985 Marion West, NC US Geological Survey (USGS) Topographic Map (Figure 2) indicates that the dam impounds an unnamed, blue -line tributary that flows into the reservoir from the south. The elevation 2 Pre -Construction Notification S&ME Project No. 7335-19-008 Lady Marion Dam April 1, 2019 of the reservoir's normal pool was estimated to be 1308', and the watershed acreage was estimated to be 403.2 acres. The surface area of the reservoir's normal pool is approximately 7.4 acres, with a storage volume of approximately 117.6 acre-feet. Based on review of the McDowell County Soil Survey, soils mapped adjacent to the reservoir consist primarily of Evard sandy loam (Typic Hapludults), Hayesville loam (Typic Kanhapludults). Soils mapped adjacent to the upstream unnamed tributary consist of lotla loam (Fluvaquentic Dystrudepts). Evard and Hayesville soils are well -drained, while lotla soil is somewhat poorly drained. The dam is approximately 400 -feet wide and 35 -feet high with a dam crest width of approximately 100 feet. A concrete spillway riser structure measuring approximately 8 feet wide by 10 feet long discharges to a concrete outlet culvert that is 6.5 feet wide and 7.5 feet tall. The outlet culvert extends northeast through the dam, beneath paved parking areas, under the Westwood Chateau Condominiums, and beneath Westwood Chateau Drive, where the culvert ties into the larger Garden Creek culvert, which conveys water in a south -to -north direction beneath the Lady Marion Shopping Center and North Main Street (US Hwy 221). Garden Creek drains to the Catawba River (DWR Index No. 11-(8), Class Q. The Lady Marion Dam riser structure is located along the dam embankment, approximately 5' from the dam crest. The riser is a grated 8' x 10' rectangular concrete box inlet structure with a lip elevation near EI. 1308'. The crest of the dam, based on available topographic information, is near EI. 1310% indicating about 2 feet of freeboard. The reservoir drain pipe projects into the riser near the bottom, approximately 6 feet above the riser culvert. From the riser, the water flows into the concrete box culvert until tying into the larger Garden Creek concrete box culvert under the shopping center and North Main Street. For purposes of quantifying impacts to jurisdictional areas associated with this project, the elevation of the normal pool surface was used to delineate the limit of waters of the US. The area beneath the jurisdictional limit is considered wetlands rather than a deep water aquatic habitat once exposed by the dewatering activities. Photographs of conditions at the site prior to commencement of draining activities are included in the accompanying information submitted with the online PCN. Description of the Work and Proposed Impacts To comply with the Dam Safety Order, the project will require that the necessary work be conducted in phases. Phase 1: Dewatering To comply with the DENR's directive to immediately begin draining the reservoir, dewatering activities commenced on February 28, 2019. The dewatering is being accomplished using diesel -powered pumps with floating intake (suction) hose and outlet piping. As the water level decreases, the pumps will be relocated closer to the lowering water surface elevation to increase efficiency and operability. The pumps will be repositioned on a portion of the embankment that is becoming exposed by the dewatering - approximately 10 feet below the dam crest. A temporary access road and a level surface for the pumps was constructed down part of the exposed embankment. Granular fill was used for the temporary access 3 s Pre -Construction Notification S&ME Project No. 7335-19-008 Lady Marion Dam a April 1, 2019 road and the level platform upon which to position the pumps. The platform measured approximately 20 feet by 20 feet, and was placed at the left upstream groin area (referenced facing downstream) at the north end of the dam. Erosion control measures necessary to prevent erosion and sediment runoff from the work area will be installed. Spill containment will be installed around the pumps to prevent fuel or oil and grease from entering the pond. Phase 2: Assessment of Reservoir Drain Pumping will cease once the water level reaches near the bottom of the reservoir. At that point, the access road will be extended all the way to the bottom of the reservoir. To provide a dry work area, a temporary soil cofferdam will be constructed in the area of the drain. The cofferdam will be constructed of compacted structural fill. In conjunction with the cofferdam construction, explorations to locate the existing drain will be conducted. Additional dewatering may be required in order to locate the drain. Once the drain is located, the (presumed) pipe will be exposed to allow for inspection by the contractor and a separate structural engineer. The drain valve within spillway riser will also be inspected for operability. If operable, the drain pipe will be extended through the coffer dam to convey base flow. The existing drain valve (assuming a flanged connection) will be removed, and the drain pipe cleaned if required. Outlet piping will be attached to the flange connection in spillway riser, and piping routed past the damaged section of box culvert for approximately 180 linear feet. This phase of the project will result in temporary impacts (fill placement and surface disturbance) within approximately 0.56 acre of jurisdictional wetland. It is likely that this phase of the project may take up to a year or more to complete. A drawing that depicts the proposed disturbance limits and impacts to jurisdictional areas are included in the accompanying information submitted with the online PCN. Phase 3: Embankment/Outlet Repair and Aquatic Habitat Restoration The final and future phase of the project will involve repairs to the existing outlet and modification of the existing embankment. Although plans to conduct the work have not yet been designed, we anticipate that fill material that was temporarily placed for construction of the access road and coffer dam will be removed and repurposed to flatten the embankment from its current 2:1 slope to a 3:1 slope for safety purposes. We further anticipate that the outlet will be redesigned and employ a concrete wing -wall system. To prevent degradation of the stream channel that is likely to develop within the footprint of the former impoundment, as well as upstream areas, a Stream and Aquatic Habitat Restoration Plan will be developed. Based on an assessment of conditions that develop over the time required to conduct Phase 2, components of the plan may include stream enhancement and stabilization, wetland restoration, creation of stormwater pockets, or similar measures designed to inhibit downstream sedimentation and upstream degradation. It is likely that the jurisdictional limits of the former reservoir will decrease over time following completion of dewatering. Accordingly, the former reservoir and immediate upstream areas will be re -delineated prior to initiation of Phase 3 so that potential impacts to remaining jurisdictional waters can be 4 Pre -Construction Notification S&ME Project No. 7335-19-008 I I Lady Marion Dam April 1, 2019 determined. An application for conducting the Phase 3 work under the appropriate NWP(s) will be submitted at that time, prior to initiation of the associated work. Protected Species To assist you in determining the project's compliance with applicable sections of the Endangered Species Act (ESA) of 1973 (16 USC 1531-1543), S&ME conducted a search of the North Carolina Natural Heritage Program (NCNHP) database to identify element occurrences (EOs) of such species listed as potentially occurring near the project corridor. The NCNHP list was compared to the U.S. Fish and Wildlife Service (USFWS) list of protected species for McDowell County. Aside from rusty patched bumblebee (eombus affinis — Federally -listed Endangered), the NCNHP report did not identify records of federally -protected species within one mile of the project site. A copy of the February 22, 2019 NCNHP report is included in the accompanying information submitted with the online PCN. S&ME also conducted a review of the FWS iPac online system. The iPac provided a list of species that could be potentially affected by the project. Those species were Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus), gray bat (Myotis grisescens), Northern Long-eared Bat (Myotis septentrionalis), mountain golden heather (Hudsonia montana) and small whorled pogonia (Isotria medeoloides). The project area does not appear to contain suitable habitat for any of the species listed above. Potentially -suitable habitat for Northern long-eared bat is present within forested areas in the vicinity of the site. However, the project area is located greater than three miles away from a HUC that contains known NLEB hibernacula and/or maternity roost trees. Accordingly, the project as proposed should not have an effect on northern long-eared bat. We anticipate that the USACE will complete the necessary coordination with the FWS and WRC prior to issuance of the permit. Historic Resources To assist in your determination of compliance with Section 106 of the National Historic Preservation Act (NHPA) of 1966, S&ME conducted a review of the NC State Historic Preservation Office (SHPO) online GIS database. Review of the database did not identify any sites that are listed or eligible for listing on the National Register of Historic Places within 0.5 -mile radius of the project site. We anticipate that the USACE will complete the necessary coordination with the SHPO prior to issuance of the permit. Avoidance And Minimization The proposed temporary workspace associated with the dewatering and repair design has been limited to the minimum amount considered necessary to safely perform the work. Impacts will be further minimized by use of appropriate erosion and sediment control measures during construction, and by conducting a pre -construction meeting to review applicable permit conditions prior to construction. 5 Pre -Construction Notification S&ME Project No. 7335-19-008 Lady Marion Dam April 1, 2019 We anticipate that compensatory mitigation for the Phase 1 and Phase 2 impacts will not be required for because they are temporary in nature. The reservoir will remain drained, and plans are to eventually reshape the existing embankment, as well as conduct aquatic ecosystem enhancement activities within the former reservoir footprint. As indicated previously, the on-site jurisdictional boundaries will be re- assessed prior to initiation of Phase 3. Work associated with Phase 3 will likely require authorization under separate NWPs. However, plans to conduct those activities have not yet been developed. The USACE/DWR will be appropriately notified in advance of these activities. Closing Thank you for your review of this PCN.

Explain the purpose of the proposed project:* According to the NCDEQ - Energy, Mineral and Land Resources Division, which regulates Danis in North Carolina, the Lady Marion Dam is classified as a small, high hazard (Class C) dam. The dam was reportedly constructed in the late 1960's or early 1970's. The adjacent Westwood Chateau Condominium complex was constructed on the dam and over an associated concrete outlet culvert. The condominiums have experienced structural problems associated with settlement. Based on previous assessments conducted by others, it is believed that internal erosion (piping) and/or deflection of the top of the culvert due to reduced structural support may be factors in the previous settlement and building distress. Existing steel bracing present within the culvert in the vicinity of the condominiums has become deteriorated and appears to have experienced buckling. The NCDEQ issued a Dam Safety Order (MCDOW-010) dated January 25, 2019 requiring preparation of plans to repair, or alternately, breach the Lady Marion Dam. A copy of the Dam Safety Order was included in the accompanying information submitted with the online PCN. In general, the Dam Safety Order required the following: (1) The reservoir shall be immediately drained per the design recommendations and oversight of a professional engineer, at a rate of no more than one foot per day. The reservoir shall be maintained in a totally drained condition until repairs or a plan to permanently breach that plan has been approved and accomplished. (2) The owners shall develop and implement an approved Emergency Action Plan (EAP). (3) Submit plans, specifications and supporting data developed by a professional engineer for repair or breach of the dam and permanent drainage of the reservoir in a manner that precludes downstream sedimentation. 41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:* To comply with the Dam Safety Order, the project will require that the necessary work be conducted in phases.

Phase 3: Embankment/Outlet Repair and Aquatic Habitat Restoration The final and future phase of the project will involve repairs to the epsting outlet and modification of the ewsting embankment. Although plans to conduct the work have not yet been designed, we anticipate that fill material that was temporarily placed for construction of the access road and coffer dam will be removed and repurposed to flatten the embankment from its current 2:1 slope to a 3:1 slope for safety purposes. We further anticipate that the outlet will be redesigned and employ a concrete wing -wall system. To prevent degradation of the stream channel that is likely to develop within the footprint of the former impoundment, as well as upstream areas, a Stream and Aquatic Habitat Restoration Plan will be developed. Based on an assessment of conditions that develop over the time required to conduct Phase 2, components of the plan may include stream enhancement and stabilization, wetland restoration, creation of stornmeter pockets, or similar measures designed to inhibit downstream sedimentation and upstream degradation.

Marion Lake Dam Dewatering Dear Ashley Bentz. The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database, indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence, the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. 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 found within the project area or is 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: httr)s://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. 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 Federally -listed species are 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 rod nev.butlerWncdcr.gov or 919-707-8603.

Five entities own or have some maintenance responsibility for a dam and its appurtenan t works on Westwood Chateau Drive, Marion in McDowell County. The dam structure and appurtenant works are located on, underneath or in association with properties of Great Meadows LLC, the Westwood Chateau Condominiums, Westwood Chateau Drive, Lady Order No. DSO -019-002 Page 2 Marion Shopping Center, and a segment of N. Main Street in Marion, North Carolina. The appurtenant works of the dam includes, but is not limited to, the spillway riser structure and all outlet conduits) from the point at which water enters the spillway/conduit system at the lake to the point at which water exits the conduit system into the Garden Creek channel north of the intersection of Garden Creek Road and N. Main Street. 2. The dam has a structural height of approximately 35 feet, and has an impoundment capacity of approximately 80 acre-feet, measured at the top of the dam. 3. The dam has the following deficiencies that threaten its integrity: A. Below grade void spaces} and/or low consistency (low velocity) soil zones that may have resulted in the visual settlement -related distress observed at the Westwood Chateau Condominiums. * (see reference below) B. Possible migration (on-going and previous) of soil materials that would result in piping associated with the barrel (box culvert from riser) of the dam * (see reference below) C. Portions of the barrel have experienced loss of integrity in the top slab, up heaving in the bottom slab, and failure of the construction support system (I -Beam network). + (see reference below) 4. The dam is classified in the high hazard category because failure of the dam poses a threat to human life and property downstream from the dam that includes but is not limited to Westwood Chateau Condominiums, Westwood Chateau Drive, Lady Marion Shopping Center, a portion of N. Main Street, Marion in McDowell County. * NCDEQ and the owners were notified of the deficiencies of the dam in a preliminary report initially delivered to the Westwood Chateau Condominiums Association, Inc representatives on January 7, 2019. This preliminary report was authored by and based on the investigative work of Mr. David Legrand, PE of Catawba Valley Engineering & Testing (CVET). + Additional deficiencies were found during the visual inspection of and review of the associated video recordings of the box culvert spillway conduits taken on January 14, 2019, by two inspectors and CVET. The deficiencies were presented in a stakeholder meeting on January 17, 2019. v 1 1 Order No. DSO -019-002 Page 3 Therefore, by the authority of NCGS 143-215.32(b) and 15A NCAC 2K.0302, it is hereby Ordered that. 1. The reservoir shall be immediately drained per the design, recommendations and work oversight of a professional engineer, licensed to work in North Carolina. The rate of draining should not exceed one foot per day (1 ft/day) unless Engineer of Record provides adequate design justification (which must be approved by NCDEQ). During the draining process, routine and regular visual monitoring of the dam should be completed and documented. Complete draining of the reservoir shall be completed within 90 days of the date of this Order. Once drained, the reservoir shall be maintained in a totally drained condition that prevents discharge of sediment until such time that repair, alteration, reconstruction or breaching of the dam is accomplished pursuant to plans and specifications developed by a licensed professional engineer and approved by the Director of the Division of Energy, Mineral, and Land Resources. ReAmpoundment of the reservoir (if any) will also require the issuance of an additional Approval to Impound issued by the Director. 2. The dam owners shall, within 15 days of the issuance of this order, submit an approvable Emergency Action Plan (EAP) to NCDEQ Dam Safety and to McDowell Emergency Management, This Plan must identify potential emergency conditions at the Dam and specify actions to be followed to minimize loss of life and property damage in the event of a potential emergency involving the dam. 3. The dam owners shall, within 91 days of the issuance of this Order, submit to this office plans, specifications, and supporting data developed by a professional engineer for the necessary repairs, alterations, or modifications required to bring the dam into compliance with the Dam Safety Law of 1967 or for the breach of this dam and permanent draining of the reservoir in such a manner that will preclude the washing of sediment downstream. tl r, J;P2 Date S.
