Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The project is located in Evans Park which is adjacent to the River Birch Tennis Center, both owned and operated by the City of Greenville. The park and tennis center feature 4 lighted tennis courts, 2 lighted softball fields, a picnic shelter, archery range, and restroom facilities. The park adjacent land use consists of single and multifamily residences. The J.H. Rose High School is located directly across Arlington Boulevard from the Park. An unnamed tributary to Greens Mill Run passes through the western edge of the park. Most of the active park recreation facilities are located to the east of the tributary. The tributary has existing crossings at two locations within the park. A 36" RCP culvert is located, on the stream in the north west corner of the park that services a drive from the main parking lot to an existing shelter with supplemental parking. This pipe and crossing is stable and is functioning as intended. The second crossing is located approximately 400 feet downstream from the first crossing within the park. This existing crossing services a sidewalk connection from the aforementioned shelter and parking area to the tennis courts located on the other side of the stream. Two pipes, one 18" CMP and one 24" CMP, convey the water at this crossing location. The existing pipes along with the surrounding fill have collapsed. The inlets of the pipes are currently buried and flow is being routed around the stream during storm events. The City has closed off the walkway with chain link fencing as it presents a danger to park visitors. Head walls were constructed at the upstream and downstream ends of the pipe. The upstream headwall has collapsed, however the downstream headwall is intact. The stream steepens at the pipe outlets in which the stream drops three feet in elevation over a 50 foot distance. The stream has incised and steep walls that flank the entrenched stream on both sides. In an attempt to stabilize the bed and banks in this reach a concrete pipe flume and concrete pavers were installed in the past. The vegetation on the western bank is comprised primarily of a small amount of brushy vegetation at the top of the bank. The eastern bank has mature trees growing on it and has been preserved in its natural state. There is an existing 24 inch CMP storm drainage system that extends from the main parking lot to the tributary. This pipe system discharges into the stream approximately 5 feet downstream of the existing 36 inch RCP pipe. The existing 24 inch CMP pipe is failing, creating sink holes in areas adjacent to the pipe. This pipe is additionally under capacity to handle the design storm event. A low area exists between the softball field dugout and spectator bleachers. 3b. List the total estimated acreage of all existing wetlands on the property: No wetlands found in work area, it is unknown if other wetlands exist anywhere else on the property. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 1230 3d. Explain the purpose of the proposed project: The purpose of the project will be to replace the existing twin pipe crossing that is currently failing with a stable crossing and excavated floodplain bench that will provide for overbank flooding relief. The existing stream channel stabilization consisting of a pipe flume and concrete pavers will be removed to return the stream back to a more native state through a boulder step pool system to transition the stream three feet in elevation. Re-establish native herbaceous and woody vegetation for long term stabilization on the stream bank and buffers. Replace 180 linear feet of existing 24" CMP pipe with a larger pipe to meet capacity requirements and to return the structural integrity back to the pipe line. Page 4 of 13 PCN Form - Version 1.3 December 10, 2008 Version 3e. Describe the overall project in detail, including the type of equipment to be used: Due to funding for improvement work in the park the project will be constructed in two phases. The first phase addresses the more immediate need within the park with the repair of the failing twin culvert pipe crossing of the tributary. The existing degraded crossing is a hazard to the public in the park. The existing pipe location is at the top of a steep stream grade. A large amount of fill was placed over the crossing which has further obstructed the flow. The fill was necessary at the original crossing location to maintain an acceptable grade through the short straight sidewalk connection across the stream. The elevation of the existing shelter on the west side of the stream is approximately 5 feet higher than the stream top of bank. The proposed pipe crossing will consist of a single 42" pipe filled to a depth of 9" to promote aquatic passage. The pipe is being relocated to an area in the floodplain in which minimal fill is required over the pipe. Minimizing this fill will promote floodplain access during storm events greater than bankfull. The location also provides for handicap accessible walkways in the park with grades that meet the accessibility standards. This new location also preserves two existing trees that are located adjacent to the stream bank. The floodplain on the eastern side of the stream will be benched for approximately 250 linear feet to provide for better floodplain access. The floodplain on either end of the bench will be connected into the natural floodplain grade. The concrete pipe flume and concrete pavers in the existing channel will be removed and a boulder and log step pool system will be installed to transition the stream grade approximately 3 feet in elevation. The elevation change through each structure will be a maximum of 6" of elevation change. The stream banks will be matted, replanted with an herbaceous native seed mix, and woody container plants will be planted for long term stabilization. Additional trees will be added to the floodplain to enhance the stream buffer. The existing concrete sidewalk will be removed and a new sidewalk installed at the alignment shown on the plans. The equipment to be used in this phase of the project is earth moving equipment and various other support apparatus. Heavy equipment may include hydraulic excavator, conpactors, bulldozers, skidsteer loaders, and material hauling apparatus such as a dump truck. This type of equipment will be used for excavation and placement of materials for the project. The construction equipment will only cross the stream within the repair area and only when base flow is being pumped around the work area. Phase II will be complete as funding becomes available for the park. The second phase of the project will include the replacement of approximately 180 linear feet of existing 24 inch CMP storm drainage pipe and two yard inlet structures. A 24" RCP and 30" RCP pipe system will be installed to increase the capacity re-establish the structural integrity of the system. An additional inlet will be added between the dugout and bleachers to improve the drainage as it has heavy pedestrian access. The replacement pipe will be placed in the same alignment as the existing pipe and will enter the tributary at the same location. Riprap exists at the end of the pipe this will be enhanced with additional stone around the newly installed pipe. The replaced vegetation will be matched to the existing vegetation over the newly installed pipe. The vegetation consists primarily of grass as this area is currently maintained by the park as lawn. The equipment used for the construction of this phase will include an excavator, dump trucks, and grading equipment. 4. Jurisdictional Determinations 4a.

Phase II will include stream impact S4. Stream impact S1 is required to restore the stream b y reconnecting it to its floodplain and providing for a step pool transition due to the extensive grade change in this area. Impact S2 is for the replacement of an existing pipe crossing of the stream the ne i . w cross ng will be replaced with two pipe sections for a total length of 16 linear feet. An existing pipe crossing that will be Page 7 of 13 PCN Form - Version 1.3 December 10, 2008 Version removed as a part of the project is currently impacting 20 linear feet of stream length. Stone/concrete headwalls and endwalls extend on both ends of the pipe. The existing crossing location is further downstream at the grade transition. The crossing location has been moved further upstream so that less fill is required over the pipe to maintain a good floodplain connection and to move it away from the severe grade transition. Additonal existing impacts in the existing stream is 57 linear feet of pipe flume in the channel bottom and concrete pavers lining the stream bottom/bank for 35 linear feet adjacent to the pipe flume. The existing headwall, endwall, pipe flume, and concrete pavers will be removed in the stream restoration. Impact S3 is required to provide for a stable transition to the pipe and to protect the pipe structure from undermining. Impact S4 will be completed in Phase II and will involve temporary impacts to the stream bank for the existing pipe replacement and riprap bank stabilization around the pipe and disturbed bank below the bankfull elevation. 4.

The impacts B2 are for a proposed walkway to connect the tennis area and shelter to an existing parking area in Phase 1. Currently there is an existing sidewalk that crosses the creek. This existing sidewalk will be removed as a part of the project. The existing sidewalk impacts that will be removed are 420 sf in Zone 1 and 304 sf in Zone 2. Buffer impacts B3 will be completed in Phase II of the project and will consist of area for access and excavation for the replacement pipe. The landscape will be restored to match existing vegetation. D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The limits of disturbance have been limited to the area that is needed for access to make the repairs. The project is necessary to stabilize the stream channel and replace failing stormwater conveyance infrastructure. The project repairs have been limited to the area that is currently degrading and the distance upstream and downstream required to stabilize the stream reach The . buffer impacts will minimize existing tree removal for the repairs and access for construction. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The stream crossing and repairs have been designed with natural channel techniques. The stream bank and buffer will be planted for long-term stabilization. 2.
