About this file
This file is a technical specification document prepared by the City of Wichita Public Works & Utilities Engineering Division that details standard wheelchair ramp construction specifications with detectable warning pavers. The document provides four distinct construction detail types for wheelchair ramps across different street configurations: Type A for streets with combined curb and gutter, Type B for streets with monolithic curb and full sidewalk, Type C for curved radius installations with six feet or more from back of curb to property corner, and Type D for combined curb and gutter with full sidewalk applications. All ramp specifications include standard widths of four feet for typical applications and five feet for school crosswalk locations, with maximum slopes of one inch per foot and removal/replacement of curb and gutter sections extending 12 inches minimum to 18 inches maximum. The construction details include expansion joints, construction joints with keyways, and precise measurements for pavement thickness variations and concrete base specifications.
The specifications mandate the use of Hanover handiCAP detectable warning pavers (or approved alternates) in all wheelchair ramp applications, with three-quarter inch red pavers required for all installations. The detectable warning pavers are to be installed on a one-half inch grout bed with concrete base and adjacent sidewalk constructed monolithic. The document was prepared by City Engineer Gary Janzen, P.E., and issued in August 2013 by the City of Wichita Engineering Division located at City Hall, 455 North Main Street, Wichita, Kansas 67202-1620. These specifications serve as standardized construction details for the City's 2026 Outsourced Pavement Preservation Program and street repair initiatives.
