Operations · Capacity
Full is a protocol, not a feeling.
The worst time to decide where the next vehicle goes is when it is stopped in the lane with another behind it. Capacity is not simply the painted-space count. It is the number of vehicles you can lawfully store, identify, access, and return under the conditions that exist right now.
Before the surge
Write the overflow ladder with the property, insurer, and local requirements in view.
Stacking and off-site relay may create insurance, access, staffing, and municipal-permit obligations. Treat them as approved operating modes only after the appropriate property, insurance, and local reviews, not as advice improvised from this article.
The overflow ladder
Escalate one controlled step at a time
Know which kind of full you are in
Physical
No legal storage remains
Every approved space is occupied or unavailable. The painted count no longer matters.
Access
Cars exist but cannot move
A blocked lane, unplanned stack, or inaccessible key can remove several spaces at once.
Curb
Intake outruns processing
The lot may have space while the entrance has none. Slow intake before the queue blocks shared access.
Retrieval
Departures cannot release capacity
Requests are arriving faster than cars can return, so the operation cannot create the spaces it expected.
→The response depends on the constraint. Sending another runner does not fix a legal-space shortage.
Run the approved sequence
Each step needs an owner, trigger, and stop condition before it can be used under pressure.
→A controlled refusal protects the guest more than accepting a car the operation cannot responsibly hold.
Guest communication should arrive before the decision feels personal. Give the property a simple status language such as normal, constrained, overflow active, and intake paused. Then connect each state to the entrance message: likely delay, alternate parking direction, or temporary unavailability. Do not promise a reopening time unless the release path is visible.
After the shift, reconstruct the capacity curve: when did usable capacity fall, which spaces became inaccessible, how many expected departures were late, and when did the curb first constrain intake? That review turns “we need a bigger lot” into a specific choice about layout, release timing, overflow authorization, or demand control.
