Environmental Features

The school is set to achieve a minimum LEED (Leadership in Energy and Environmental Design) ‘Silver’ designation, making it an HCPSS “Green School.” A “Green” school is a building designed to conserve energy, water and materials, thus reducing negative impacts on human health and the environment.

Roof mounted solar photovoltaic panels will generate electricity and reduce the amount of power needed from the power company by 18%.

Rainwater will leave the site at the same rate as before the site was developed. Native plant species will be planted around the school so that irrigation is not required. Underground cisterns will gather the rainwater to reduce the rate of run-off and can also be used to irrigate the sports fields. Micro-bioretention areas have been built throughout the site to filter the impurities from the stormwater before it enters the local waterways.

LED lighting fixtures will be provided throughout the school—including the Stadium—and will include cut-off lights to reduce unwanted glare to the neighboring homes.

Dedicated recycling areas have been designed throughout both the exterior and interior of the school grounds to support the school’s recycling program.

All materials used to create this high school have been selected for their sustainability features. The paint and adhesives are low VOC which contributes to better indoor air quality. In addition, many of the building finishes, such as the flooring, paint, insulation, doors, windows, and cabinetry are locally sourced and made of recycled materials.

Athletic Facilities

Main gymnasium capacity: 2,139 people

Bleachers will accommodate 1,180 spectators

Auxiliary gym capacity: 737 people

Stadium capacity: 3,517 seats, making it the largest stadium in the County

Five acres of natural turf sports fields, including Softball, Baseball, Field Hockey, and multi-purpose fields. The Stadium includes track facilities and an artificial turf field. Additionally, the campus has six asphalt tennis courts and two and a half asphalt basketball courts.

Sports facilities include two gyms, a wrestling room and a fitness room with associated team and locker rooms.
