One commuter train station within a half-mile walking distance is sufficient to meet the credit requirement. This can be a local metro, subway, light rail or long-distance commuter line. Alternatively, two bus lines within ¼ mile walking distance can satisfy the credit requirement. These can be private, public, or campus bus lines. For Schools, the school bus line can count as one of two bus lines.

For residential spaces, base the number of occupants on the number and size of units. Assume two residents for a one-bedroom apartment, three residents for a two-bedroom apartment, etc.

To document the credit create a vicinity site map, to scale, illustrating the building in relation to the bus lines or rail stations that will be used for compliance. A delineated walking route from the project to the transit stop is also recommended.

Typically, the tenant or LEED consultant is responsible for documenting access to public transportation and should identify local stations and bus routes closest to the project, reaching out to local transit authorities if necessary.

In the case of a retail project, calculate full-time, shift-equivalent numbers for both employees and customers. This can be determined by using actual or historical data, projections, or estimations based on square footages and building type. In all three cases, assume 50% male and 50% female occupants. See the USGBC website for more information on LEED for CI Retail projects.

A transit-oriented project may need less parking area, contributing to SSc3.1—Alternative Transportation: Parking Capacity. You can also reduce your costs for parking construction, maintenance, and stormwater infrastructure and fees.

In multi-tenant buildings this credit can be extremely difficult to achieve, as purchases throughout the building must be documented for all tenants. There are two common difficulties—getting tenants to participate, and then, if they do participate, aggregating purchasing information from a variety of individual tracking systems.

A transit-oriented project may need less parking area, contributing to SSc4.4: Alternative Transportation—Parking Capacity. You can also reduce your costs for parking construction, maintenance, and stormwater infrastructure and fees.
