Lot Coverage / Impervious Surface

The maximum percentage of a lot that can be covered by impervious surfaces (buildings, parking, driveways). Controls stormwater runoff.

Lot Coverage = (Building Footprint + All Hard Surfaces) ÷ Lot Area × 100
Full Definition
Lot coverage (often stated as maximum impervious surface ratio) limits the percentage of a lot that can be covered by hard surfaces — building footprints, parking areas, driveways, and sidewalks. The remaining area must be pervious: landscaping, green space, or pervious paving systems.

?
- ? Footprint of all structures ÷ lot area. Controls building bulk.
- ? All hard surfaces ÷ lot area. Drives stormwater retention requirements.

? C-2 has a maximum impervious surface ratio of 60%. Any impervious area above 60% requires on-site stormwater retention — typically wet detention ponds or underground exfiltration systems — designed per SJRWMD standards.

? On a 1-acre (43,560 sf) lot with 60% max coverage, you have 26,136 sf of impervious surface budget for your building footprint + parking. A 5,000 sf QSR building + 80 parking spaces (~26,400 sf) barely fits. Structured parking increases the FAR without consuming impervious budget.
📐 Practical Example

43,560 sf lot × 60% max coverage = 26,136 sf max impervious area for building + parking combined.
