Black Mountain Golf Course
Town of Black Mountain, NC
2020
Problem:
Tributary to Tomahawk Branch needed to be moved back to the natural channel location.
Solution:
Tributary to Tomahawk Branch was moved back to the natural channel location. It was moved in 1928 when the course was built. This created ponding beside an old channel in the fairway and accelerated flow.
Lake Tomahawk Sediment and Dredging Project
Town of Black Mountain, NC
2020
Problem:
The Tomahawk branch undermined the pedestrian bridge and the lake is filling up with sediment.
Solution:
Armour bridge footer with tiered boulder system to concentrate flow under the center of the bridge. Build cross vane to center flow under the center of the bridge. Cross vane also backs flow up before Lake Tomahawk which causes sediment to drop. Benches installed on both sides of the dredging area to allow for hydraulic dredging.
Flat Creek
Town of Black Mountain, NC
2020
Problem:
Flood events are undermining the parking lot and flooding the buildings.
Solution:
Flat Creek in Black Mountain at the confluence of Flat Creek and Swannanoa River. Boulder toe installed with soil lifts made of coir logs. Log vane installed at the beginning of the project to divert energy to the center of the channel.
Problem:
McClure's Bog receives runoff from a 26-acre subwatershed.
Solution:
McClure's Bog is a French Broad River Valley Bog subtype and hosts a
unique community of threatened and endangered species including
Mountain Sweet Pitcher Plants and Swamp Pink, as well as habitat for
Bog Turtles. McClure's Bog receives runoff from a 26-acre subwatershed. As a result, a series of tiered basins were designed and constructed to store and infiltrate rainfall. The area was then planted with a robust and diverse suite of herbaceous, shrubs, and tree species upon completion of grading.
Big Lost Cove Creek Stabilization
Headwaters Engineering, Asheville, NC
2020
Problem:
The cabin foundation was being compromised and subject to failure. Big Lost Cove creekbank needed to be stabilized.
Solution:
Soil lift with bio-engineering. Foundation of cabin exposed by high water events from the creek. A rock/boulder toe installed without having to enter the waterway. Once the toe is installed a soil lift structure built with coir logs and vegetative whips planted on each course.
