Biographical
William Hunt
Dr. Hunt is an Associate Professor and Extension Specialist in North Carolina State University's Department of Biological and Agricultural Engineering department. Hunt holds degrees in Civil Engineering (NCSU, B.S., 1994), Economics (NCSU, B.S., 1995), Biological & Agricultural Engineering (NCSU, M.S., 1997) and Agricultural & Biological Engineering, (Penn State, Ph.D., 2003). Dr. Hunt is a registered PE in North Carolina.
Since 2000, Hunt has assisted with the design, installation, and/or monitoring of over 90 stormwater best management practices (BMPs), including bioretention, stormwater wetlands, innovative wet ponds, green roofs, permeable pavement, water harvesting/cistern systems and level spreaders. He teaches 20-25 short courses and workshops each year on stormwater BMP design and function throughout NC and the US.
Hunt is an active member of the American Society of Agricultural and Biological Engineers (ASABE), serving as NC Section President and as Past-Chair of the National ASABE Extension Committee. He is also a member of the American Society of Civil Engineers (ASCE), where he serves on the Urban Water Resources Research Council, the LID committee, and is co-chair of the Bioretention Task Committee. He was chair of the 2nd National LID Conference held in Wilmington, NC, in March 2007. Locally, he is a member of the Neuse Education Team, NC Watershed Education Network and the NC Association of Extension Specialists.
He is an avid Wolfpack sports fan and enjoys
traveling, spending time with friends and family, stormwater
management, and wearing a diverse variety of sweater vests. He is the
proud father of 2 boys (Bill and Joseph) and is lucky to be married to
Julia Claire Hunt.

horticultural plants at Fayetteville Technical Community College.
7. Boone, NC. 3,000 gallon tank used to supply street sweeping and
winter brine water for the Town of Boone.
Mosquitoes and Stormwater BMPs
A grant funded by the Urban Stormwater Consortium of the N.C. WRRI.
NCSU staff are sampling 52 ponds and wetlands across NC for presence
and relative quantity of mosquitoes. The project was completed in
January, 2005. Dr. Charles Apperson of NCSU Entomology Department was
the co-PI. In short, most facilities did not have a mosquito problem.
The limited number of facilities that did (12 of 52) had one of the
following characteristics: wooded, covered by cattail monoculture,
floating trash/debris/, and/ or algae.
Impacts of these and other research findings on wet pond and stormwater wetland design standards are found in the following Extension Bulletin by Hunt, Apperson, and Lord. A short summary of the project is available in a CALS Perspectives article.

Stormwater BMP Inspection and Maintenance
Standards
A grant funded by the Urban Stormwater Consortium of the N.C. WRRI is
comprised of the following 4 objectives:
1. Develop a requirement list for inspection and maintenance for 7
stormwater BMPs including wet ponds, stormwater wetlands, bioretention
areas, sand filters, green roofs, underground detention, grass swales,
dry detention, and permeable pavement.
2. Determine minimum and standard inspection and maintenance
frequencies for the above BMPs
3. Provide rationale fro choosing maintenance standards and frequencies.
4. Estimate costs associated with minimum and standard inspection and
maintenance and estimate costs of NOT performing said tasks at a given
frequency.
The final report has been submitted for review to the WRRI. It is
expected to be made available in 2008.
A Stormwater BMP Inspection and Maintenance
Certification Program has been developed as part of this research. A
direct link to the program website is found here.
Determining Urban Pollutant Loads
Work has been conducted to determine the amount of pollution generated
from urban land uses.
1. A series of parking lots were examined in NC to estimate nutrient
loads from parking lots and to contrast these to those reported for
other transportation surfaces (2006-2007). Funded by NC DENR.
2. A 500-acre watershed (House Creek) is being monitored at 6 locations
to estimate pollutant loadings from the following land uses: golf
course, highway interchange, institutional (museum + park), and an
agricultural setting. Funded by NC EEP and NC DOT (2006-present)
3. First flush characterization of two watersheds on the NCSU Campus.
