Super-sized restoration projects begin in Hyde

Super-sized restoration projects begin in Hyde | Research from the NC Agricultural Research Service | Scoop.it

By Catherine Kozak, Coastal Review Online | With numerous bureaucratic hurdles finally cleared, an innovative wetlands restoration project led by the N.C. Coastal Federation is about to begin on thousa...

CALS Research, NCSU's insight:

Dr. Mike Burchell & engineers in the CALS Department of Biological & Agricultural Engineering are designing a canal complex intersecting with farmland in Hyde County. Pumps & weirs will redirect rain stormwater into a created wetland, protecting the Albemarle & Pamlico Sounds of North Carolina. Read more | http://tinyurl.com/kgb7ucg

CALS Research, NCSU's insight:

Rain means untreated stormwater can sweep pollutants into coastal waters, potentially endangering public health. NC State University researchers have developed low-cost filtration systems concealed beneath sand dunes to filter out most of the bacteria that can lead to beach closures.

N.C. Department of Environment and Natural Resources Grant to CALS Engineers

N.C. Department of Environment and Natural Resources Grant to CALS Engineers | Research from the NC Agricultural Research Service | Scoop.it

CALS Biological & Agricultural Engineers and Agricultural Economists have received a grant of $203,775 from the NC Department of Environment & Natural Resources (DNER) for Phase II of a project in Cary, NC. Phase I created rain gardens and other rainwater harvesting systems at schools. The next phase of the project will focus on stormwater controls along greenways and in community parks.

 

Project researchers are economists, Dr. Christy Perrin, Dr. Patrick Beggs & Dr. Layra Taylor, and engineers, Dr. Kristopher Bass & Dr. William Hunt, III.

 

Here's how the researchers describe their project:

 

"The Black Creek Watershed Association (BCWA), coordinated by NC State University with technical assistance from the Town of Cary since 2006, has achieved several milestones in its pursuit of delisting Black Creek from the 303(d) list of impaired waters.

 

"An initial watershed assessment and restoration plan was completed in 2009, followed by acceptance of the plan by EPA in lieu of a TMDL. The assessment showed that the creek is impaired by high volume and velocity stormwater runoff flows that have altered the natural flow regime and negatively impacted biotic communities. The partnership created a residential outreach and engagement program that resulted in many residential practices that are reducing stormwater runoff through backyard raingardens, and wetlands.

 

"Public stormwater retrofits have been installed at schools, a neighborhood clubhouse, and a private greenway. In-stream flow monitoring and modeling produced 3 years of data and a hydrologic model for assessing target runoff reductions. This proposal will leverage successes achieved to reach a new significant landowner audience- commercial and institutional landowners.

 

"BCWA is known through public outreach events and networking with members' organizations (Rotary clubs, homeowners' associations). The network will help to convene a commercial/institutional steering committee to develop and implement an outreach, sponsorship, and recognition program. A retrofit project will be identified and implemented on a commercial property, and retrofits that were previously identified within the project BMP Site Atlas will be constructed on Town of Cary and Wake County schools properties. Simple changes to existing bioretention will be installed and monitored to increase infiltration.

 

"Additional stream flow monitoring and modeling will further hone a retrofit target by testing pre-post BMP flows, and will test a new milestone of disconnecting 200 acres of imperviousness to reach effective 10% impervious cover in the watershed. Ultimately, this project will lead to a greater capacity of the community to fund and implement stormwater retrofit projects, and to better understand the type and cost of retrofits needed to move towards a more natural stream flow regime."

Study Exposes Multi-generational Impacts of Pesticide Exposure - eNews Park Forest

Study Exposes Multi-generational Impacts of Pesticide Exposure - eNews Park Forest | Research from the NC Agricultural Research Service | Scoop.it
Using the aquatic species Daphnia, commonly referred to as “water fleas,” scientists at North Carolina State University (NC State) determined that exposure to the pesticide pyriproxyfen impacted multiple generations, ultimately resulting in more...
CALS Research, NCSU's insight:

The team of toxicologist, Dr. Gerald LeBlanc, found that in the model aquatic organism, exposure to the pesticide pyriproxyfen (an insecticide in the juvenile hormone analog (JHA) class) resulted in adverse reproductive effects in females, and production of more male offspring, skewing the sex ratio, with severe effects on future reproduction.  Read news article |  http://tinyurl.com/aou94bn | Paper appears in PLos One | http://dx.doi.org/10.1371/journal.pone.0061715

CALS Research, NCSU's insight:

A large-scale water quality project in New Bern, designed NC State’s Dept. of Biological & Agriculture Engineering (BAE), received national recognition for its construction. Cape Fear Precast LLC of Jacksonville was awarded second place for a local project in the National Precast Concrete Association’s Creative Use of Precast (CUP) Awards in January.

 

The Jack Smith Creek Stormwater Project, one of the largest stormwater retrofits in NC, was designed by Cooperative Extension’s BAE Stormwater Group in CALS and involved the construction of a stormwater wetland to capture and treat runoff from a large watershed in New Bern. The innovative project can capture and treat the runoff from more than 1,000 acres of residential and commercial property.
