Smart Parking Lot Design and ADA Compliance: How Davidson A+E Delivers Accessible, Efficient Sites

By: Hilary Zerr, P.E., LEED AP, Partner

When planning a commercial development, the parking lot is often the first impression visitors have and it’s more than just asphalt and stripes. A well-designed parking lot ensures safety, accessibility, and compliance with ADA standards, while supporting traffic flow and stormwater management. At Davidson Architecture + Engineering (DA+E), we bring civil engineering expertise to create parking solutions that meet regulatory requirements and enhance user experience.

Why ADA Compliance Matters

The Americans with Disabilities Act (ADA) requires accessible parking spaces, routes, and features for individuals with disabilities. Non-compliance can lead to:

• Legal penalties and fines

• Costly retrofits

• Negative customer experiences

Key ADA requirements include:

• Accessible parking spaces with proper dimensions and signage

• Van-accessible spaces with extra width and access aisles

• Smooth, slip-resistant surfaces

• Accessible routes from parking to building entrances without steep slopes or obstructions

• 
  

Engineering Beyond Compliance

At DA+E, we go beyond minimum standards to design parking lots that are:

• Efficient: Optimized traffic flow and clear wayfinding

• Durable: Proper grading and drainage to prevent ponding and pavement failure

• Sustainable: Integration of stormwater BMPs like biofilters and permeable pavements

• Safe: Well-lit, clearly marked pedestrian paths and ADA-compliant ramps

• 
  

Our Role in Site Design

Parking lot design is just one piece of a successful site plan. DA+E provides:

• Site grading and drainage solutions

• Utility coordination

• Stormwater management and water quality features

• Permitting and code compliance support

By combining technical precision with creative problem-solving, we help property owners and developers deliver projects that meet today’s accessibility standards and tomorrow’s sustainability goals.
