PATH 2. CONNECTED SITE
When selecting a project location, it is important to consider whether the parcels directly adjacent or on the other side of the road are previously developed sites. The more previously developed land that exists along the border of the project parcel means that existing infrastructure is reused, and the need for new construction materials is reduced, decreasing greenhouse emissions and reducing the environmental impacts from new construction.
The project team must identify parcels adjacent to the project’s perimeter on a map and determine whether the project meets the criteria for an adjacent site or infill site. Teams must measure the project’s entire perimeter, the length of perimeter segments adjacent to the waterfront (if any) and the longest continuous perimeter segments adjacent to qualifying parcels.
Use Equation 1 to determine the percentage of the project boundary that is continuously adjacent to previously developed parcels. The site qualifies as an adjacent site if the total meets or exceeds 25%, excluding any waterfront adjacency.
Equation 1. Percentage of adjacent boundary for adjacent sites
% 𝑎𝑑𝑗𝑎𝑐𝑒𝑛𝑡 𝑏𝑜𝑢𝑛𝑑𝑎𝑟𝑦
= [𝐶𝑜𝑛𝑡𝑖𝑛𝑢𝑜𝑢𝑠 𝑝𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 𝑎𝑑𝑗𝑎𝑐𝑒𝑛𝑡 𝑡𝑜 𝑝𝑟𝑒𝑣𝑖𝑜𝑢𝑠𝑙𝑦 𝑑𝑒𝑣𝑒𝑙𝑜𝑝𝑒𝑑 𝑝𝑎𝑟𝑐𝑒𝑙𝑠] × 100
(𝑇𝑜𝑡𝑎𝑙 𝑝𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟−𝐴𝑛𝑦 𝑤𝑎𝑡𝑒𝑟𝑓𝑟𝑜𝑛𝑡 𝑝𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟)
Equation 2 can be used to determine if the site qualifies as an infill site. If at least 75% of the project’s boundary is adjacent to previously developed parcels, excluding any waterfront perimeter, the site qualifies as an infill site.
Equation 2. Percentage of adjacent boundary for infill sites
% 𝑎𝑑𝑗𝑎𝑐𝑒𝑛𝑡 𝑏𝑜𝑢𝑛𝑑𝑎𝑟𝑦
= [𝐴𝑛𝑦 𝑝𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 𝑙𝑒𝑛𝑔𝑡ℎ 𝑎𝑑𝑗𝑎𝑐𝑒𝑛𝑡 𝑡𝑜 𝑝𝑟𝑒𝑣𝑖𝑜𝑢𝑠𝑙𝑦 𝑑𝑒𝑣𝑒𝑙𝑜𝑝𝑒𝑑 𝑝𝑎𝑟𝑐𝑒𝑙𝑠] × 100

Option 5. Access to Transit or Pedestrian Access
PATH 1. ACCESS TO TRANSIT
Same as Option 2, Access to Transit above. Transit access to schools ensures that workers, students, and families can access the school facility.
