The accessible route is the core of ADA compliance. For McKinney commercial properties, the route from accessible parking spaces to the building entrance must be continuous, unobstructed, and compliant. We install and repair curb ramps that connect the parking lot to the walkway, ensuring the ramp has the proper slope, width, and detectable warning surface.
For historic downtown properties, the building entrances are a particular challenge. Many downtown buildings were built with steps or raised entrances that do not meet current accessibility standards. We install ramps that provide accessible access to these entrances, using designs that are both compliant and appropriate for the historic context. The ramp materials and design are selected to complement the historic character of the building. The sidewalks around the square may have heaved due to soil movement or tree roots, creating non-compliant slopes or trip hazards. We repair or replace sidewalk sections.
For US-75 corridor properties, the curb ramps and routes see highway traffic. The striping and route surfaces need to be durable enough to handle the traffic. For new construction along SH-121 and Eldorado Parkway, the curb ramps and routes are typically built to current standards, but we verify the as-built conditions.
The building entrance is a critical point. For McKinney properties with older entrances, the door hardware may not meet current opening force requirements, the thresholds may be too high, and the door clearance may be insufficient. We install or modify door hardware, adjust thresholds, and ensure the entrance meets current standards.
The expansive clay soil in Collin County is particularly active. The soil movement can affect ramp slopes over time. We re-measure ramp slopes during every audit and recommend corrections. For historic downtown properties, the soil movement can affect the historic foundations, and the ramp installations need to account for the ongoing movement.
For properties with multiple levels or changes in elevation, we install or repair ramps that connect the levels. The ramps must have the proper slope, width, landings, and handrails. For historic downtown properties, the ramps need to meet current standards while respecting the historic character.
The path of travel must be free of obstacles. For downtown properties, outdoor seating, displays, and event signage can obstruct the route. For new construction, the wide sidewalks and plazas need to be kept clear. We identify any obstacles and recommend relocation.
