3.4 Access to Quality Transit
Key Takeaways
- LT Credit: Access to Quality Transit (1-5 pts) requires transit stops within 1/4 mile walking distance for bus, streetcar, or informal transit, and 1/2 mile for rail, ferry, or bus rapid transit (BRT).
- Service must meet minimum daily and weekend trip thresholds — typically 72 weekday and 40 weekend trips for 1 point, scaling up to 360 weekday / 216 weekend trips for the full 5 points (BD+C NC).
- Trips from multiple transit lines are aggregated, but each line must independently provide service in both directions to count.
- The walking distance is measured along actual pedestrian routes from a functional building entrance, not as a straight-line radius.
- Planned transit service must be funded and scheduled to open within 24 months of certification to count toward the credit.
Purpose and structure
LT Credit: Access to Quality Transit encourages building placement near frequent, high-quality public transportation to reduce single-occupancy vehicle trips and the parking infrastructure that supports them. Points (1-5 for BD+C: NC) scale with the number of weekday and weekend transit trips reachable from the project.
Two numbers control eligibility: walking distance to the stop, and number of daily trips served by all qualifying stops combined.
Walking distance by transit mode
The credit uses mode-dependent walking-distance thresholds, measured along the actual pedestrian route from any functional building entrance.
| Transit Mode | Maximum Walking Distance to Stop |
|---|---|
| Bus, streetcar, informal transit (e.g., jitney, paratransit) | 1/4 mile (≈ 1,320 ft) |
| Bus rapid transit (BRT), light rail, heavy rail, commuter rail, ferry | 1/2 mile (≈ 2,640 ft) |
A common exam trick is to assign the 1/2-mile walk to bus stops or the 1/4-mile walk to rail. The mnemonic: higher-capacity, higher-investment modes (rail/BRT/ferry) get the longer walk, because riders will walk farther for higher-quality service.
Daily trip thresholds
For BD+C: New Construction, the typical thresholds are:
| Weekday Trips (sum) | Weekend Trips (sum) | Points |
|---|---|---|
| ≥ 72 | ≥ 40 | 1 |
| ≥ 144 | ≥ 108 | 3 |
| ≥ 360 | ≥ 216 | 5 |
Both the weekday AND weekend thresholds must be met at each step. A project with abundant weekday commuter rail but no Saturday/Sunday service will fall short.
Multimodal counting
Multiple lines can be added together if each line:
- Has at least one qualifying stop within the mode-appropriate walking distance.
- Operates in both directions along the route.
- Provides scheduled service (commuter shuttles serving only the project do not count unless they are publicly available).
Trips at the same stop from the same line in the same direction count once per scheduled arrival. Express buses and local buses that serve the same line but with different stops can both contribute.
Planned transit
Planned future service may be claimed if:
- The transit project is funded.
- A published implementation schedule indicates service begins within 24 months of the project's expected certification date.
- The team supplies the funding source and operator contact.
If the planned line slips, the credit can be revoked at recertification or audit.
Walking distance details (often missed)
- Measured along publicly accessible pedestrian routes (sidewalks, plazas, marked crosswalks). It cannot cut through private parking lots that the public cannot legally traverse.
- Begins at a functional entrance of the building (employee, public, or service entrance), not the project boundary edge.
- A pedestrian bridge, tunnel, or signalized crossing counts as a continuous route segment.
Strategic implication
Urban projects often satisfy the 1-point threshold trivially because a single subway station provides 200+ weekday trips by itself. Reaching the 5-point tier usually requires being near a multimodal hub — a rail station plus several bus lines plus weekend service. Suburban office parks served only by peak-hour express buses typically fail the weekend threshold even when weekday trips are abundant; this is the most common reason teams forecast 3 points and earn 1.
During schematic design, the team should obtain the local transit authority's published schedule, draw the mode-specific walk shed, count trips at each qualifying stop on a representative weekday and weekend day, and confirm both totals exceed the target tier.
A LEED BD+C: NC project's main entrance is 1,800 feet (≈ 0.34 mile) along sidewalks from a light rail station and 1,500 feet (≈ 0.28 mile) from a bus stop on a local route. Which stops qualify under LT Credit: Access to Quality Transit?
A project documents 380 qualifying weekday transit trips but only 32 qualifying weekend trips. Under the typical BD+C: NC scale for LT Credit: Access to Quality Transit, what is the highest point tier the project can claim?
