When can planned stops and stations contribute towards "access to quality transit"?

The correct choice clearly aligns with the LEED criteria for accessing quality transit. For stops and stations to contribute toward this credit, they must not only be sited and funded but also under construction at the time the certificate of occupancy is issued. This ensures that the transit infrastructure is not just a future possibility but is actively being developed to serve the building occupants.

Additionally, the completion timeline is crucial; allowing for completion within 24 months after the certificate of occupancy ensures that the transit improvements will be realized in a reasonable timeframe relative to the building's occupancy. This approach supports the intent of promoting sustainable transportation options and creating walkable communities.

Considering the other options, operational status by the project's completion date does not necessarily guarantee that the transit will be functional and usable for building occupants right away. While being funded and under construction is important, the timeframe for completion is equally critical to ensure accessibility to transit concurrently with occupancy. Therefore, the most comprehensive and effective answer emphasizes the comprehensive development of the transit infrastructure related to the LEED certification process.
