Sustainable Sites (SS)

The Sustainable Sites (SS) category is about making decisions based on having less impact to the environment.It covers decisions from the time before ground disturbance activities begins and ends with native landscaping and light pollution.

An example of this category is Marshall University capturing the stormwater runoff from the new Arthur Weisberg Family Applied Engineering Complex (AEC) building underground and allowing the first one inch of rain to percolate into the soil and for ground water recharging. A total of 26 points are possible from this category. Marshall University attempted to earn a total of 21 points, with one point being questionable and four points that were not attempted/eligible.

3     d Credit 4.3 Alternative Transportation—Low-Emitting and Fuel-Efficient Vehicles
        A 20% discount is required to meet credit requirements
        Provide preferred parking for fev for 5% of total vehicle parking.
        One low emitting or fev must be provided per 3% of FTE occupant
2     d Credit 4.4 Alternative Transportation—Parking Capacity
        No new parking
    1 C Credit 5.1 Site Development—Protect or Restore Habitat
      Limit site disturbance to :40′ beyond building perimeter, 10″ beyond walkways and parking, 15′ beyond primary roadway curbs, and 25′ beyond constructed areas
      Restore or protect a minimum of 50% of site (excluding building footprint) or 20% of the total site area (including building footprint), whichever is greater with native plants
    1 C Credit 5.2 Site Development — Maximize Open Space
      Local zoning requirements define open space
      Site w/ zoning ord. but NO OPEN SPACE reqs require 20% open space
