About the Project
Alluvial Decoder, is a site-specific education installation about the floodplain at Crabtree Creek near the greenway trail on Glenwood Avenue and Crabtree Valley Avenue.
Meaning of the Project Name
Here’s how the designers chose the name for the project:
Alluvium is the sediment left in the areas around a water source after a flood. This is an essential part of the floodplain.
Decoder references the fact that the project helps people understand more about the floodplain. You can see just how high creek water gets during tropical storms and hurricanes that reached Raleigh throughout the years.
Importance of Floodplain Education
Heavy rain from major storms, like the ones shown in this educational installation, can cause water in creeks to rise quickly. When this happens, stormwater flows out of the creek to nearby land giving the rain a place to go.
This flooding cannot be prevented and typically impacts greenway trails, roads, and buildings in the area. It’s important to be aware of flooding and stay safe during a storm.
However, the floodplain also helps reduce flooding. The plants and soils in the floodplain help slow down and soak up some of the water, which leads to less severe impacts to the community and the environment downstream.
This project will add a new meadow and visual displays. Learn more about each aspect of the project below.
We are transforming an area along Crabtree Creek near the greenway trail on Glenwood Avenue and Crabtree Valley Avenue into a meadow. To do this correctly, we will be keeping the grass long. Then, we’ll mow and overseed the meadow to maintain it. We'll do this each spring.
A mural under the bridge displays the name of storms that have caused flooding in Raleigh. The names are Agnes, Fran, Eta, Hanna, Alberto, Kyle, Matthew, Danny, and Floyd.
A series of markers represent several historic floodwater heights. A key under the bridge reveals names and dates of the storms represented.
Installation Completed in Fall 2021
As hurricane season begins, join us on Wednesday, June 1 from 4 to 6 p.m. for the formal opening of Alluvial Decoder — an immersive, educational installation on the Raleigh Greenway at Crabtree Creek. Lincoln Hancock, William Dodge, and William Belcher (A Gang of Three) will be present to talk about the system of flood markers, the reinstituted wildflower meadow, and the experiential graphic elements that comprise the project.
