Page 10 of 10 Documentation for Pre -Construction Notification (PCN) Form 1535 Caraleigh Mills Court, City of Raleigh, NC B. Project Information and Prior Project History 3a. Project Description The project property is a condominium development located at 1535 Carleigh Mills Court. The watershed is a fully developed with primarily 1/4 acre residential lots and commercial land use with some open spaces and forested areas. The project involves stabilization of a stream at an existing crossing location and grading of the existing floodplain to provide floodwater access on a section of an unnamed tributary to Walnut Creek located on the property. 3b. List the total estimates acreage of all existing wetlands on the property No wetlands are located and within the limits of disturbance for this project. It is unknown if wetlands exist in other areas of the property. 3d. Explain the purpose of the project The purpose of this project is to stabilize the stream bank in the area of the existing crossing and provide for stormwater flow through the flood plain along the unnamed tributary to Walnut Creek through grading. The existing concrete abutments for the foot bridge have been undermined and the bridge is not currently supported on either end by anything but the soil at the top of the embankment. The south embankment fell into the stream some time ago and the north abutment has more recently fallen in early 2016. The existing bridge is planned to be removed and a boardwalk constructed by the HOA in the future. 3e. Describe the overall project in detail, including the type of equipment to be used. The proposed improvements include removing the concrete abutment in the channel and stabilization of the northwest stream bank with a rock toe. The stream has over widened in this area due to the bridge constriction and recent abutment loss. The rock toe, 35 feet in length, will be placed at a location in the channel that restores the appropriate geometry. No other channel improvements or impacts are planned for the stream bank or bed. Grading of the floodplain will occur along the channel within the limits of disturbance to remove the approach for the fill to the bridge crossing, provide for a wider floodplain and a more gradual slope on the terrace banks. The floodplain will be graded to allow stormwater access to it, reducing channel stressors. The floodplain will be replanted with herbaceous and woody vegetation for long term stabilization. The floodplain area is currently being maintained. Excess soil from the grading operations will be placed on site in an existing grass area adjacent to the dog park and street. This area will be re -seeded with grass to match the existing conditions. The permitted work in this PCN request also includes a future boardwalk planned by the HOA to be installed by others. An approximate location of the boardwalk and associated trail has been shown on the Impact Map. The HOA does not have drawings for the boardwalk at this time. A schematic of future boardwalk elevations and dimensions has been included with the proposed construction plans. The equipment to be used in the project is earth moving equipment and various other support apparatuses. Heavy equipment may include hydraulic excavator, compactors, bulldozers, skidsteer loaders, and dump trucks to load and unload materials. The construction equipment will enter the site from Maywood Avenue through an existing curb cut will perform all construction within a defined limit of disturbance. One temporary bridge mat crossing of the stream is proposed to enable equipment to access the southeast side of the stream for grading operations. C. Proposed Impacts Inventory Ai CnmmPnta- B 1: Floodplain and terrace bank grading along northwest and southeast sides of the stream. The area will be re -graded, matted, and re -vegetated. 132: Waste Soils Grading: Excavated material will be wasted on site in the existing grass lawn area. Area will be re -vegetated to match the existing grass on site. B3: Construction access: The areas outside of B 1 and B2 that are being used for temporary construction access to get to the stream channel or work on grading areas outside of the graded footprint but inside of the limits of disturbance. Construction access areas will be through corridors of currently maintained grassed areas. No trees are planned to be removed for access. This area will be re -seeded with grass to match the existing conditions. B4: Future boardwalk and trail impacts: A boardwalk and trail will be constructed by the HOA in the near future to replace the existing damaged crossing being removed through the City of Raleigh Petition Program project. The boardwalk will span the stream and will be set on pilings with a minimum low chord elevation of 252.0 ft. Minimal fill will be required within the buffers to provide ADA compliant slope for the trail to meet the top chord elevation. It is understood that fill material will not be placed in the floodplain. The buffer area at this crossing is currently grass that is being maintained as lawn in the buffer. B5: Future temporary construction access to construct the future bridge and trail connection has been estimated for this impact as a distance 15 feet on either side of the proposed trail/boardwalk alignment. D. Impact Justification and Mitigation Ia. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The existing bridge crossing has become unstable with the loss of both of the abutments. The existing bridge caused a restriction in the channel and destabilized the channel geometry and the terrace bank adjacent to the bridge. This project is necessary to remove the bridge restriction and stabilize the stream channel. The grading of the floodplain and stream bank repair will eliminate the active erosion that is occurring on the stream channel and steep terrace banks. Replanting the floodplain with woody vegetation will promote long term stabilization. The relocation of the crossing further downstream and providing a long boardwalk to avoid constricting the floodplain flow will minimize the impacts to the stream with this new crossing structure. lb. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The construction will be performed from the floodplain with one crossing proposed for equipment. No crossing of the stream will be permitted with construction equipment. The proposed structural measures include rock for stability at the stream toe and vegetation to re- establish root systems on the stream bank for long term stabilization. PA F. Supplementary Information 5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? The site is an existing urban residential area that has been previously impacted by development. Habitat is not present for Wake County listed vertebrate and invertebrate endangered species with the exception of Northern Long Eared Bats. Open areas adjacent to the stream are currently being maintained. The project requires removal of a few bushes for access. No trees are planned to be removed as a part of this project. Therefore it is not anticipated that there will be any adverse impacts associated with T/E species. 3 _ Tpp IGAS GAS--- 58—� \ - -.- - GAS AS 0 -257-'\\\ _° t—cas cas / C/� ma�D EXISTIING GAS W �� ZN \\ NCRETE SIDEWALK GAS GAS W W °: v> s z -,,' ,2 ,' : EXISTING�sa / — GAS, - W �^• Ys= EXISTING DOG PARK sRIPRAP I ' �' x / _ -�.
