Biltmore Hills Park Green Stormwater Infrastructure
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 used to flow from the park into the creek without any treatment, contributing to flooding, streambank erosion, and sedimentation. This contributed to impacts on aquatic wildlife, water quality, and residents’ health and finances when homes are flooded.
Our Plan
Several partners united to address the issue by designing and installing green stormwater infrastructure (GSI) projects to reduce stormwater runoff from Biltmore Hills Park. Together this project helps reduce erosion, reduce Rochester Heights Creek’s flow, reduce pollution and stormwater flows that contribute to flooding.
GSI Definition
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.
GSI Plans
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 was funded by an EPA Clean Water Act Section 319 grant, which support projects to address non-point source pollution in impaired watersheds, A NC Department of Justice Ecosystem Enhancement Grant (EEG), and City of Raleigh Stormwater funds. The project began in 2021. After design and a bid process, construction was provided by the lowest bidder, Fluvial Solutions, Inc., in late 2023- early 2024. Educational signs were installed by City of Raleigh in early 2025.
