Commercial Parking Lot Planning Guide

A well-planned parking lot does more than provide spaces — it manages traffic flow, meets code requirements, protects pedestrians, and controls vehicle speed. Here is what goes into planning parking lot improvements.

Striping Layout — Parking lot striping starts with the lot dimensions and the required number of spaces. Standard parking spaces are 9 feet wide and 18 feet long, but dimensions vary by local code and lot type. Compact spaces, ADA spaces, fire lanes, no-parking zones, and directional arrows all need to be planned before any paint goes down.

ADA parking requirements specify the number of accessible spaces based on total lot capacity, plus access aisle widths, signage height, and proximity to building entrances. Getting these wrong is one of the most common code violations in commercial parking lots.

Bollard Placement — Bollards protect building fronts, utility equipment, pedestrian areas, and loading zones from vehicle impact. Placement depends on what you are protecting and the likely angle of vehicle approach. Standard bollards are concrete-filled steel pipe set in concrete footings. Removable bollards allow access when needed. Decorative bollard covers improve appearance in retail settings.

Speed Bump Specifications — Speed bumps are typically 3-6 inches high and 1-3 feet wide. Speed humps are wider and lower, creating a gentler deceleration. The right choice depends on the speed you need to control, the type of vehicles using the lot, and whether emergency vehicle access is a factor.

Planning Considerations — Before starting parking lot improvements, consider: current lot condition (does the concrete need repair or replacement first?), drainage patterns (will striping or bump placement affect water flow?), traffic volume and patterns, local code requirements, and timeline for completion.
