Designing Stormwater Control Measures for Hominy Creek in the City of Wilson

Sponsor: City of Wilson

Start Date: 5/01/20

End Date: 11/30/21

Abstract

Faculty, staff, and students from NC State University’s Biological and Agricultural Engineering’ Stormwater Engineering Group (hereafter NCSU SEG) will design six different stormwater retrofits for future grant submission for the City of Wilson. These projects will all treat sub-catchments of Hominy Branch. The retrofits to be designed include: (1) a large, multi-acre off-line stormwater wetland, (2 and 3) a pair of green alleys in downtown Wilson, (4) a floating wetland island installation in an existing wet pond, (5) the development of an engineering structure and (6) a channel stabilization and linear wetland creation at the headwaters of Hominy Branch. As part of the SCM design, NCSU SEG will survey most of the projects, acquire permits, and monitor one of the tributaries. They will also assist the City of Wilson with the bidding process and construction supervision (were grants to be awarded).

Greenfield Lake 319 Wet Pond Retrofit

Sponsor: US Environmental Protection Agency (EPA)

Start Date: 6/01/20

End Date: 12/31/21

Abstract

As a subcontractor to Cape Fear River Watch, the NCSU Stormwater Engineering Group will design, install, and provide monitoring equipment and oversight for an innovative treatment berm retrofit. While wet ponds are effective at attenuating peak flows, previous research has shown inconsistent pollutant removal efficiency. As ponds are a popular SCM in North Carolina, the improvement of their pollutant removal efficiencies is essential in nutrient sensitive watersheds. To address these treatment shortcomings, research has recently focused on retrofits to existing wet ponds to improve nutrient removal. A reactive treatment berm will be installed on private property by a project partner as directed by NCSU. NCSU will partner with one of the nation’s largest stormwater maintenance companies (Apex Companies) to construct and maintain the retrofit.

Swale Research in Continued Support of NCDOT’s Stormwater Program

Sponsor: NC Department of Transportation

Start Date: 1/01/20

End Date: 5/31/20

Abstract

Swales are the most prevalent stormwater conveyance - and therefore potential treatment device - within NCDOT’s linear right-of-way. To date, swale performance with respect to hydrologic change and pollutant retention has been assumed to be modest; however, initial NCDOT-funded research on hydrologic condition (wetland versus upland) and check dam presence has yielded basic results that lead to some potential design improvements. To date, a comprehensive and systematic research program of post-construction swale performance has yet to be conducted. Because swales are such a common practice, small but defined design improvements could yield substantial improvements in runoff quality and quantity released to receiving waters. The purpose of this proposal is to continue swale research support for the NCDOT Stormwater Program. Plot testing has been conducted at NCSU’s Sediment and Erosion Control Research and Education Facility (SECREF) and continued modifications and maintenance of swales is needed. Multiple swale design parameters continue to be tested in this controlled setting, including channel slope, vegetation height (or type), end-of-swale treatment and hydraulic loading ratio. Furthermore, additional swale research is planned utilizing the constructed swales at SECREF. This proposal will continue research and support of further swale design, as well as swale modification, maintenance and repair in support of the NCDOT Stormwater Program.

Abstract

North Carolina State University (NCSU), Biocenosis, and the Piedmont Conservation Council (PCC) are partnering to construct stormwater control measures (SCMs) throughout the impaired Loves Creek watershed to improve water quality and reduce localized flooding. Additionally, educational workshops will be held to encourage the implementation of residential SCMs.

Abstract

A pervious concrete and stormwater treating street tree treatment train is going to be installed in Burlington, NC. NCSU will be cooperating with the City on the installation, monitoring, and dissemination of the project. The site will be located in downtown and focus on water quality and hydrology. If successful, this tandem of practices could become one of the most popular in downtown retrofits in NC.

Abstract

The Town of Wake Forest will remove a failing pond/dam, re-establish the geomorphology of Dunn Creek, and implement two floodplain wetlands at Ailey Young Park. NC State University (NCSU) will monitor the stream restoration and floodplain wetlands for 11 months and or 15 water quality storm events. NCSU will also analyze the data and synthesize the results in a final report to the Town of Wake Forest.

Clean Little Alamance from the Y Up (formerly CLAM Project) (DEQ Task Order #7932)

Sponsor: US Environmental Protection Agency (EPA)

Start Date: 7/18/19

End Date: 8/31/20

Abstract

Little Alamance Creek, which drains a large portion of the City of Burlington, NC, is a 15.9 square mile 303-d listed stream for poor benthic health. A 2014 Category 4B Demonstration plan was developed listing restoration and improvement goals of the watershed, including stormwater BMP retrofits for common urban water quality stressors. A 9-element plan (the Little Alamance, Travis, and Tickle Creek, or LATT, plan) was subsequently developed using the 4B as guidance and accepted by the North Carolina Department of Environmental Quality (NC DEQ) in 2015. North Carolina State University and the City of Burlington are proposing to partner and install a stormwater BMP at a city-owned site behind the Maynard Aquatic Center. The stormwater runoff generated by a parking lot and grassed area from this site drains to an open, grassed area about 125 feet upslope of Little Alamance Creek. The proposed BMP is a planted bioretention cell to treat and infiltrate the runoff. The bioretention cell be monitored for hdyrologic and water quality effectiveness. Efforts will be made to engage in public outreach via workshops, public signage, and any local news media on the retrofits. At least one workshop (on retrofits) will be held in the Burlington/ NC Triad area while another 1-2 workshops will be given across NC.
