Current Activity

Posted Monday, Dec. 18

Dewberry is completing design plans for this project, which were presented at a public meeting on Oct. 18. During this meeting, Dewberry and City staff discussed the current status of the project and received feedback from residents regarding the recommended reconstruction plan for White Oak Lake. The finalized design plans will be submitted to the City's Development Services Department for review in January 2018.

Dewberry also has coordinated with U.S. Army Corps of Engineers, North Carolina Department of Environmental and Natural Resources (NCDENR), and North Carolina Dam Safety who will oversee the environmental permits for the project.

North Carolina Dam Safety has confirmed that the lake is a small, high hazard dam and will require an emergency action plan to prepare for a potential dam breach. The requirement to model a dam breach was waived for this project since there is historical modeling of the nearby I-440 culvert. The U.S. Environmental Protection Agency (EPA) plan is currently being developed to account for the dam's high hazard classification.


White Oak Lake is a privately owned lake that provides little reduction to peak flows for the downstream Simmons Branch watershed. However, retrofit improvements to increase the lake’s ability to store stormwater runoff will reduce flooding in the downstream watershed that currently experiences fairly frequent flooding of roads, yards, garages, crawl spaces, and HVAC units.


Project schedule with dates and descriptions
Spring 2017Stormwater models finalized, 70 percent of the project design plan developed, and environmental permits submitted
Fall 2017Recommended design alternative presented
Winter 2018Project bid, private utility relocation, permit application, easement acquisition, and finalized construction plan complete
Spring 2018Project design complete
Summer 2018Project construction begins
Winter 2019Project construction complete


The White Oak Lake drainage improvements are the last part of a multi-phased project that will reduce flooding in the Simmons Branch watershed. Other projects included culvert improvements at Ravenwood Drive, Kaplan Drive, Lail Court, Swift Drive, and the Simmons Branch Drainage Improvement Project - Phase II.
