Municipal and ADA-Compliant Drainage Systems for Public Spaces
From parks and pools to splash pads and sidewalks, effective drainage systems are essential to keeping public spaces safe and accessible throughout the summer. Today, municipalities require drainage solution systems that are not only efficient and reliable — but also ADA-compliant to protect those with disabilities.
Drainage design is a key component of compliance, as improperly placed or uneven grates can create obstacles or trip hazards. Drainage Solutions Inc. (DSI) provides municipalities, contractors, installers, engineers and landscape architects with high-quality, ADA-compliant products that help prevent hazards, reduce liability and ensure infrastructure performs reliably.

What ADA Compliance Means for Drainage
Under ADA standards, drainage systems must maintain smooth transitions between surfaces, avoid large openings that could trap wheels or canes and ensure slopes meet accessibility requirements. Compliance not only fulfills legal obligations but also demonstrates a community’s commitment to inclusivity and safety.
ADA Compliant vs. Heel Proof — What is the Difference?
A grate designated as “heel proof” is also ADA compliant, the only difference being that heel proof grates have even smaller max openings of only 1/4″.
Key Features of ADA-Compliant Drainage Systems
Designing an ADA-compliant drainage system involves more than functionality; it requires careful attention to surface details, materials and installation, including:
- Surface Smoothness: Transitions between grates and adjacent surfaces must be flush, minimizing bumps or gaps. A smooth finish allows wheelchairs, strollers and mobility devices to move seamlessly across.
- Slot Width and Orientation: According to ADA guidelines, openings in gratings should not exceed ½" in width. Additionally, the slots should run perpendicular to the direction of travel to prevent wheels or canes from catching.
- Proper Slope and Alignment: Walkways should not exceed specific slope ratios. For instance, cross slopes greater than 2% can create balance challenges. Proper alignment ensures water flows naturally without creating dips or uneven patches.
- Non-Slip Surfaces: ADA-compliant drainage solutions often feature slip-resistant coatings or textures. This minimizes the risk of slipping, particularly during rainy conditions.
- Placement Considerations: Drainage structures must be strategically located to avoid high-traffic paths. Positioning them at natural low points away from main walking routes helps maintain accessibility while effectively managing runoff.
ADA-Compliant Products That Make a Difference
Iron Age Designs Decorative Grates
All Iron Age grates are ADA compliant, which means they have openings no larger than 1/2″ in the dominant direction of travel. ADA guidelines also call for accessible floor and ground surfaces that are stable, firm and slip-resistant. Our inventory of Iron Age Designs raw cast metal grates exceed these criteria, in both wet and dry conditions.

NDS Dura Slope: A “System Backbone” Product
NDS Dura Slope is a pre-sloped trench drain system designed to collect and move surface water efficiently across flat or low-slope areas like sidewalks, parking lots, public spaces and infrastructure projects
NDS Dura Slope trench drains are designed to meet ADA requirements when paired with specific, compliant grates. Many Dura Slope grate options — including plastic, stainless steel and galvanized slot tops — are designed as ADA-compliant and heel-proof, featuring 1/2". slots or specialized perforation.
Keson Measuring Tools
From sturdy and reliable measuring wheels to long and short tape measures designed for high visibility and durability, Keson offers a wide assortment of measuring tools designed to meet the high accuracy and durability standards required for professional, industrial and ADA-related compliance work. While Keson does not directly offer a "certified ADA compliant" tool, their products allow inspectors to verify that features like ramps, sidewalks and parking lots meet ADA guidelines.
