North Woods Project

The Northwoods at Lake Avondale Project is a stormwater mitigation project to prevent erosion in the Northwoods and to reduce sediment and pollutants into Lake Avondale.  The project uses green infrastructure features that will slow and filter stormwater entering the Northwoods from Berkeley Road and provide visual enhancement.  Paths and an accessible trail within the Northwoods will provide educational and passive recreation opportunities for citizens and visitors to enjoy this treasured resource.  The project is funded in part by a grant from the Georgia Department of Natural Resources' Land, Water. and Conservation Fund (LWCF).

If you have visited the Northwoods at Lake Avondale recently, you may have noticed the white and pink tags hanging from branches of understory trees. Additionally, every large tree has a shiny blue medallion on its trunk, with a number that corresponds to a tree inventory to document size, tree species, condition of the tree. 

Long Engineering (Long) and Lord Aeck Sargent (LAS), the engineering and design consultant team for the project, recently completed topographic and wetland surveys, as well as an extensive tree survey of the Northwoods. The surveys, particularly the inventory of large trees, will inform the design and placement of trails and green infrastructure facilities for slowing and filtering stormwater before entering Lake Avondale, to be the least impactful to our trees.  The City’s LWCF grant, from the Georgia Department of Natural Resources (GA DNR), will help fund construction of the project, to scheduled to begin in mid-June 2021. The consultant team presented their design plans at an upcoming information session, via Zoom, on March 16. Watch a replay of this presentation below. Download the presentation here.

A topographic survey of the area bounded between Berkeley Road and the Boy Scouts building was completed on January 15. Included in the survey are the delineated states waters and jurisdictional waters regulated by the US Army Corps of Engineers, this includes all wetlands within the proposed site. The tree survey of all trees 6” and above was completed on February 5th. The tree survey includes size, species, and the condition of the tree. The amount of stormwater water entering the proposed site through the existing inlets on Berkeley Road has been calculated and used to size the surface area of the proposed rain gardens. These rain gardens will clean the water of any suspended solids before releasing the water into the lake. Currently the design team is looking at different pond configurations to minimize impact to the existing trees and integrate into the surrounding esthetics.
