Liberia House Stream Restoration

This project will restore approximately 1,800 linear-feet of eroded stream banks along Flat Branch Creek through the Liberia House Property, located at 8601 Portner Ave. The goal is to stabilize stream banks and protect infrastructure, such as the historic Spring House situated along the stream. The project will also result in TMDL credits to help the City reach our pollution reduction goals.

Cultural Resource Survey

The project site contains historic resources, and a portion of the site is located within a Virginia Department of Historic Resources (VDHR) easement. As such coordination, input, and review of a Phase I survey by VDHR was completed.
Within the project's limits of disturbance is a historic spring house. The project has been designed to avoid current and future impacts to the springhouse. There is no proposed work within the immediate area of the springhouse other than relocation and fill of the existing stream channel. In fact, the grading of existing, eroding slopes are designed to prevent overland flow from threatening the stability of the springhouse. During construction, installation of the orange safety fence buffer will be used during the construction sequence to prevent impacts to this resource.
