Multi-Area Streambank Restoration

The City of Hendersonville's Multi-area Streambank Restoration Project will restore approximately 13,000 linear feet of streambanks and will protect existing infrastructure while improving stream health and water quality. The project consists of streambank restoration efforts at thirteen sites throughout the City, a stormwater wetland retrofit at Patton Park and other stormwater management components. The project also consists of sanitary sewer replacement and upgrades at three sites including one within Patton Park.

The purpose of the project is to restore sections of several urban streams along with their associated vegetative buffers, which will help promote stormwater quality measures and improve the overall quality of Mud Creek - an impaired water. The project will incorporate bioengineering practices using native riparian vegetation. This natural approach restores the ecological and hydrological balance of the stream by utilizing structurally sound, economically feasible and ecologically sustainable methods. Restoration methods will vary by site but will include bank shaping and planting; construction of riffles and pools; installation of rock vanes and vegetation geolifts (eroded streambanks are graded to a stable slope and native vegetation is installed); the reestablishment of riparian buffer; and the use of native vegetation.

Streambank restoration will also serve to protect existing sewer infrastructure. This will decrease the possibility of clean water entering the sanitary sewer system and also reduce the likelihood of a future failure of sewer piping or manholes, which would lead to sewage entering streams. The project is expected to take approximately ten months to construct. The City obtained a North Carolina Department of Environmental Quality zero interest loan to fund the project.

Patton Park

The site with the most visibility and complexity of work is at Patton Park and along Brittain Creek. Phase one of the Patton Park project began mid-October 2019 with sanitary sewer upgrades occurring first. The existing 18" clay sewer line will be replaced with a 24" PVC line. A portion of the walking trail at Patton Park will be inaccessible during construction and signage will be posted to alert park users.

In addition to stream buffer enhancements and invasive species removal, the Patton Park project will also involve the construction of a stormwater wetland.

The existing pond within the park drains an adjacent parking lot but does not provide stormwater treatment in the area. The water is especially turbid, or muddy, and engineering staff have plans to make the area more functional and aesthetically pleasing. Modifications to the pond will convert it into a stormwater wetland accompanied by recreational amenities and educational signage. Later in the project, a bioswale and a section of permeable pavement will be installed in the parking area to better manage stormwater. The City of Hendersonville was awarded a NC-319 Grant from the NC Department of Environmental Quality to help fund a portion of the new stormwater control measures in Patton Park.



Project Updates

  • 3/12/21 - Stormwater Stroll educational signage in place at Patton Park. 
  • 1/21/21 - Repairs made to a section of streambank at the Allen Branch-US 64 site. Walking trail repair work completed at Patton Park.
  • 12/18/20 - Comet Drive Restoration has been completed and the Lakewood site has been cleaned up and seeded. A majority of the work at Patton Park has been completed with the construction of the willow tunnel, benches and plantings still to come. Paving portions of the walking trail and other concrete repairs are planned.
  • 8/13/20 - In Patton Park, all sewer lines have been tied in. Work to abandon the old sewer line will completed over the next month. Wetland grading and stream restoration on Brittain Creek has started. Many of the other streambank restoration sites have been completed or are nearing completion. Allen Branch/US64 is complete with the following sites substantially complete: Alen Branch/Lakewood, Haywood Townes, Cherry Branch.
  • 7/16/20 - Sewer line testing and cleaning has continued at the Patton Park site.  The Patton Park sewer line installation, tie-ins, and testing should be completed over the next month. Streambank restoration projects have been occurring throughout the area. Projects have been completed on Old Chimney Rock Road, Meadowbrook Terrace, and substantial work at Allen Branch/US64 and Allen Branch Lakewood Site. Wetland construction at Patton Park will resume following the finalization of the sewer line work. 
  • 6/26/20 - Multiarea Streambank Restoration Plan for Patton Park
  • 6/2/20 - In Patton Park, the new sewer lines have been installed underground. However, there is final testing and closed circuit televising (CCTV) of the piping that will be taking place through the end of June. Once that work is complete, the parking areas will be prepped and ready for asphalt. Also beginning in June and lasting through the end of August, the constructed stormwater wetland and Britton Creek stabilization work will be completed within the park. The above timeframes represent a range and are subject to change depending on weather conditions.

March 2020

  • 3/4/20 - Work has begun on a section of the parking lot that will be replaced with permeable pavers. Permeable paving systems allow water to infiltrate the pavement and are just one of the stormwater features being incorporated at Patton Park.
  • 2/25/20 - Weather delays and undercut issues have slowed sewer line installation progress. Contractors plan to begin adding Saturdays and Sundays into the construction schedule (weather permitting) to expedite the installation of the sewer line thru the parking lot areas. During construction there will continue to be areas of the parking lot closed and one way access to the ball fields at either of the pedestrian bridges. 
  • 1/22/20 - Construction is continuing on the sewer line replacement. Heavy rain events and contractors encountering unsuitable soils have caused some delays in the construction timeline. The sewer line installment is expected to be completed in mid-March. Some invasive species removal is already occurring along the streambanks. Following completion of the sewer line installation at Patton Park, stream buffer enhancements, invasive species removal, and the conversion of the pond into a stormwater wetland will occur on the site. This portion of the project is expected to be completed by Fall 2020.
  • 1/22/20 - The Engineering Department creates a story map outlining the streambank restoration sites.
  • 12/3/19 - The contractor will continue to provide signage for park visitors to gain access to the Oklawaha greenway. During the sewer line installation, there will be times when the trail access at the gazebo is closed and visitors will be directed to the pedestrian bridge at the Patton Pool parking lot for greenway access.
  • 12/3/19 - 10 parking spaces next to the basketball court and gazebo area will be closed for material storage. There will be times the parking lot and drive between the basketball court and skate park will need to be closed during construction. During these times, the public will be able to park in the back parking area and the upper portion of the front parking lot.
  • 12/2/19 - Installation of the proposed sewer line scheduled to begin. The line will be installed in the grassy area between the existing basketball court and gazebo thru the parking lots and drives for the skate park, bathrooms, and pool areas. Certain drive and parking lot areas will be shut down during construction. These areas will be affected by construction for at least two months depending on the weather.
  • 11/21/19 - Contractor is cleaning up and temporary seeding near the basketball court area.
  • 10/23/19 - Contractors are installing safety fencing to block off the construction area.
  • 10/23/19 - In preparation for sewer line construction, Duke Energy has removed some trail light poles at the north end of Patton Park. The trail lights from the Gazebo to the north end of the construction area will be off until certain portions of the construction are complete. Following construction, trail lights will be replaced.
  • Mid October - Contractors will begin Sewer line replacement in Patton Park. Portions of the walking trail will be inaccessible during construction. See closure map.
