A Suburban Medical Office: Parking, Transit, and a Private Shuttle
A 45,000 ft² medical office building is planned on a suburban campus. The site already has a 120-space surface lot serving an existing 25,000 ft² clinic; the new building will share that lot and add no spaces. Local code requires 1 space per 250 ft² of gross floor area, which for the combined 70,000 ft² would be 280 spaces. A public bus stop sits 0.4 miles from the entrance with three weekday peak trips and two weekend trips. The hospital operates a private shuttle every 30 minutes to a rail station three miles away; riders must show a hospital ID. The nearest public bicycle path is 0.3 miles away, but the building has no showers or secured bike storage. The owner wants to know which location and transportation credits are realistically achievable and what would need to change.
1. Assess the parking situation: does the project qualify for a reduced parking footprint, and what is the risk?

The arithmetic is favorable but it needs a legal check before it becomes a credit strategy.
- Supply versus code: 120 spaces for 70,000 ft² is well below the 280-space code minimum. A reduced-parking credit generally rewards supply at or below the jurisdiction's minimum, so the project is in a strong position on that test.
- Shared parking: the lot serves both the clinic and the new building. Document the shared-use arrangement and the peak-hour assumptions; a shared lot can support the credit narrative, but only if the sharing is real and enforceable, not informal.
- The real risk is entitlement, not LEED: a project 160 spaces below code minimum will likely need a variance or a shared-parking agreement to be approved. If the jurisdiction refuses and the owner must build more parking, the credit position changes overnight.
- Credit also needs strategies, not just arithmetic: preferred parking for carpools and vanpools, secured bicycle storage, and shower/changing facilities are the kind of measures that complete the picture.
Recommend confirming the zoning approval path in writing before promising the credit to the owner.
2. Evaluate the transit and shuttle service against access-to-transit criteria.

Separate the two services, because they fail for different reasons.
- Public bus: the stop is within walking distance, which is good, but three weekday trips and two weekend trips is very thin. Access-to-transit credits require a minimum number of qualifying trips, and the threshold varies with the surrounding density; at three weekday trips the project is unlikely to clear it in most contexts. Verify the exact threshold for the applicable rating system and density before ruling it out.
- Private shuttle: frequency and destination are attractive, but a shuttle restricted to hospital-ID holders is not public transit. A qualifying transit service is generally one open to the public. The ID requirement is the weak point, not the 30-minute headway.
- Walking distance: confirm the actual pedestrian route to the bus stop, not a straight-line measurement across a parking lot or a highway ramp. A hostile crossing can invalidate an otherwise qualifying distance.
Realistic conclusion: the project probably does not earn the transit credit as currently configured, and the shuttle cannot be counted simply because it exists.
3. Recommend a prioritized set of actions to capture the most location and transportation points with limited budget.

Prioritize by cost per point and by how much control the project has.
- Bicycle facilities first: the path is 0.3 miles away, and secured bicycle storage plus showers and changing rooms are comparatively cheap in a new building. This is the most controllable credit on the list.
- Preferred parking for carpools and vanpools: restripe a small number of the existing 120 spaces. Low cost, immediate, and complements the reduced-parking narrative.
- Make the shuttle count, or don't claim it: options are to open it to the public, or to work with the transit agency on a publicly available circulator. If neither happens, exclude it from the credit analysis rather than arguing for an exception.
- Negotiate bus service: approach the transit agency with a written request for additional trips, or explore a transit-agency partnership. A commitment letter is worth more than a schedule that may change.
- Surrounding density and diverse uses: document what exists within walking distance-the clinic, retail, and services on campus may already support a credit without any capital cost.
Sequence the free documentation items first, then the low-cost site measures, and treat the transit negotiation as a long-lead item with a fallback.
