• Biltmore Hills Park sits in the Biltmore Hills neighborhood upstream from Rochester Heights. Both have historic value as the first Black planned developments in Raleigh. Residents near Rochester Heights Creek face frequent nuisance flooding. Heavy rain flows from the park into the creek, contributing to flooding, streambank erosion, and sedimentation. This impacts aquatic wildlife, water quality, and residents’ health and finances when homes are flooded.
  • Several partners have united to address the issue by designing and installing green stormwater infrastructure (GSI) projects to reduce stormwater runoff  form Biltmore Hills Park. Together this project will help reduce erosion, reduce Rochester Heights Creek’s flow, reduce pollution and stormwater flows that contribute to flooding.

What is GSI?

  • Green stormwater infrastructure (GSI) is a nature-based solution to environmental issues at many scales, including forests, wetlands, and streamside buffers. This can include rain gardens, green roofs, or tree plantings for example.
    • At Biltmore Hills Park,  GSI include a bioretention swale at the community center to reduce runoff from the roof, bioretention by the community pool to control runoff from the parking lot, and cisterns to harvest and re-use rainwater.

Timeline and Funding

The Biltmore Hills Park project is funded by an EPA 319 grant, which support projects to address non-point source pollution in impaired watersheds.  The project began in 2021, with engineering and design, construction, performance monitoring, and education to be completed by summer 2023.

A 3D model of a bioretention on the edge of the Biltmore Hills park community center. The retention is composed of a brick wall barrier built onto the side of a small hill. The brick wall has is surrounding a large layer of soil.There are several plants including grasses and small trees planted in the soil. At the bottom of the brick wall is a small circular opening that allows water moving through the soil to exit the bioretention.
