"Provide dedicated bike lanes that extend at least to the end of the school property in 2 or more directions with no barriers (e.g., fences) on school property." This requirement seems vague in the actual purpose but very explicit in the requirement. The credit purpose is to encourage bike use. The bike lane part is I assume for safety, but school campuses have many possible configurations and this requirement needs to be less rigid to allow for solutions that work with campus plan, layout and logistics.
