White Oak Lake Reconstruction Project
- Storm Drainage System / Dam Retrofit
- $3 million
- Stormwater Management (Lead)
- Dewberry (Design)
Posted Friday, Nov. 9
Dewberry is completing the design plans for this project, which were shared with residents during a public meeting in March and with North Carolina Dam Safety in April. The final design plans should be finished this month.
Environmental permits for the project were approved by U.S. Army Corps of Engineers and North Carolina Department of Environmental and Natural Resources (NCDENR). Final approval from North Carolina Dam Safety is expected this month.
Also, design plans were submitted to the City's Development Services Department for review to make sure the design meets current standards.
Construction is expected to begin in early 2019 rather than this fall to avoid starting major construction (i.e. removing water from the lake) during the winter.
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.
|Spring 2017||Stormwater models finalized, 70 percent of the project design plan developed, and environmental permits submitted|
|Fall 2017||Recommended design alternative presented|
|Fall 2018||Project design, private utility relocation, permitting, and easement acquisition complete|
|Winter 2019||Project construction begins|
|Winter 2020||Project 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.
