Rocky Branch Walnut Creek

Rocky Branch & Central Walnut Creek Watershed Study

Downtown/South Raleigh Area

Updated: Jul 14, 2023

We are doing a study of the Rocky Branch Watershed and the adjacent portion of the Walnut Creek Watershed located in southern downtown Raleigh.  The goal is to identify ways to improve the watershed by:

  • Reducing flooding impacts
  • Renewing stormwater pipes and infrastructure that is in poor condition
  • Improving water quality
  • Repairing streambanks

Study Area: In and near downtown Raleigh.

Provide your feedback and observations on stormwater issues and concerns with our Rocky Branch and Walnut Watersheds Study Survey and view the live results.

Planning

The study is being completed in phases. The first phase is beginning in spring 2023 and focuses on:

  • Initial public engagement,
  • Collecting field data on the location and condition of streams & stormwater infrastructure, and
  • Determining additional data needs to assess the watershed.

The second phase will include data evaluation, modeling and analyses, and identification of improvement projects. The study is anticipated to continue through 2024.

Current Work

Our field crews and consultants are performing surveys to determine:

  • Location, size, and type of stormwater infrastructure
  • Stream conditions and measurements of stream banks and channels

This work is anticipated to be complete by Fall 2023.

About the Study Area

The watershed study area covers over six square miles and is shown in the map below.  This includes all of Rocky Branch Watershed and a portion of Walnut Creek Watershed.  These are two of the 36 watersheds in the city. Learn more about the Rocky Branch Watershed.

The study area is roughly bounded on the west by I-440, on the north by Hillsborough Street and New Bern Avenue, on the east by Peyton Street, and on the south by Western Boulevard and Walnut Creek. 

The rain that falls within this boundary finds its way through stormwater pipes, ditches, and streams to Walnut Creek then to the Neuse River.
