Sunset Oaks Subdivision – Holly Springs, NC (2004-2011)

•    Land planning and construction drawings including layout, grading/drainage, utility and erosion control for over 510 single family homes on 100 acres.

•    Project broken into 12 major phases for construction drawing approvals.

•    Site was difficult in that the property has a large amount of varying elevation and overlooks of a mapped stream.  The design was worked to save those vistas and minimize the earthwork required for the infrastructure completion and lot design within each phase – further reducing transfer of soils between phases and around new roadway/utility infrastructure.

Haywood Community College, Creative Arts Building – Clyde, NC (2010-2013)

•    Civil Engineering design and construction administration of a 41,000 square foot education lab building with a construction cost of $9,193,000.

•    Existing site was a heavily wooded south-facing hill with proposed architectural design requiring solar access and daylighting opportunities with natural ventilation and the retention of as many existing trees as possible.

•    Included design for a roof rainwater capture system for flushing and irrigation reuse and a deck overlooking the stormwater sand filter treatment area feature.

•    Additional design included demolishing the existing adjacent building and parking area.

•    Deliverables included preliminary site layout options, Construction Drawings, Construction Administration and As-Built record set.

•    The Creative Arts Building is expected to be certified as the first LEED Platinum Higher-Education classroom/lab building in North Carolina.

Cherry Branch Ferry Operations Center and Sitework – Craven Co, NC (2011-2015)

Swan Quarter Ferry Operations Center and Sitework – Hyde County, NC (2011-2015)

•    Roof rainwater capture system
    -    Removes additional impervious area from point source flow into harbor
    -    Provides beneficial reuse of natural resources for toilet flushing and irrigation at new operations center

•    Stormwater infiltration
    -    Retrofit infiltration trenches into existing stormwater swale to allow more infiltration and reduce nitrogen load into harbor
    -    Routing of stormwater through overland grassy swales to allow greater infiltration and to reduce nitrogen load into harbor
    -    Routing of overflow building downspouts through planned landscaping to utilize the natural rainwater in the root systems of the native plantings

•    On-site septic system (Cherry Branch site only)
    -    Utilize LPP septic system to pressure dose the new septic field on site
    -    Designed overexcavation of trenches to provide chimneys for septic effluent to infiltrate better into the existing sandy soils layer approximately 4.5’ below the ground surface 

•    Removal of on-site septic system (Swan Quarter site only)
    -    Designed new force main to remove wastewater from current site septic system and tie to public sanitary district for treatment

•    Net Zero Discharge from Ferry Boat planning
    -    Designed ferry boat removal system whereby waste from the ferry restrooms would be pumped onto shore through a designed system and into the on-site septic system as discussed above
    -    Removing point source discharges into the river shellfish waters

Northern Guilford Middle School – Guilford County, NC (2004-2008)
Northern Guilford High School – Guilford County, NC (2004-2008)

•    Holistic water cycle approach that incorporates bioswales and wetlands and a highly conserving water system (rainwater flushes toilets, goes to a Living Machine to an underground irrigation system for three ballfields on site)
    -    This use of rainwater and recycled wastewater  saved the client a cost of over $4 Million that would have been required to bring municipal water and sewer service to the site

•    Rainwater catchment system 
    -    360,000 gallon cistern  (top is a basketball court)
    -    Rainwater used for toilet flushing
    -    Rainwater used for firefighting system

•    Well onsite for drinking water (only ~10% of the required water use for the site)

•    Toilet waste goes to on-site, bioaquatic Living Machine system that cleans 30,000 gallons of water a day
    -    Water goes into storage tanks to be used for irrigating the athletic fields
    -    Athletic fields utilize an underground trip tubing system whereas no spray is put on the fields (High School Football stadium, High School soccer field and Middle School football field) and the system uses 40% less water than conventional sprinkler systems.

•    Three constructed wetlands (storage capacities of 84,000, 52,900, and 110,410 cubic feet) and four bioswales were created to divert stormwater around the site to the wetlands without the use of curb and gutter and the reduction of stormwater piping costs

•    Design of nine play fields (two football, one soccer, two practice fields, two baseball and two softball fields) along with two additional septic fields as a backup procedure as this sub-surface wastewater irrigation scheme was the first in the nation to be approved.

Project recognized in 2007 Beyond Green Award – Northern Guilford Middle School - Sustainable Building Industry Council

Wilkes County Rest Area – Wilkes County, North Carolina (2004-2006)

•    Preliminary design of rainwater catchment from roof for flushing toilets inside the building
•    Preliminary design of waterfall feature for entrance using recycled water (signifying the mountains to the sea)
•    Preliminary design of bioswale/wetlands for treatment of runoff from truck parking and car parking areas
•    Preliminary design of natural slope filter for runoff of area down into bioswale through bioaquatic plant life (bog slopes)

Project recognized in "On the Road to Green" – Case Study of the NCDOT Wilkes Visitors Center in Solar Today magazine, May 2011

Pamlico Community Health – Bayboro, NC (2012-2013)

•    Site plan for 8,500 square foot health care center, 40 parking spaces and stormwater control on a tight 1.5 acre site adjacent to the 100 year floodplain in Pamlico County.

•   Designed site to reduce costs focusing on removal of stormwater piping, balanced grading and utilizing existing driveway access points to adjacent Highway 55.

•    Stormwater designed as a constructed wetland to meet nitrogen removal requirements with existing seasonal high water table at the ground surface.

•    Deliverables included three (3) preliminary site layout options, Construction Drawings, Construction Administration and As-Built record set.

•    Deliverables included preliminary site layout options, Construction Drawings, Construction Administration and As-Built record set.

•    The Creative Arts Building is expected to be certified as the first LEED Platinum Higher-Education classroom/lab building in North Carolina.
