Like many cities, Pekin has struggled keeping up with their sidewalk infrastructure needs. However, unlike others, Pekin entered into a Consent Decree requiring them to address pedestrian accommodations. TWM served as a technical advisor during the finalization of the Decree, providing an ADA Transition Plan based on mobile LiDAR data. This data was used to create a GIS database that cataloged every data point, making the information accessible to both City staff and residents. TWM also ranked and prioritized locations based on factors like the City’s budgetary capabilities, proximity to schools, degree of non-compliance, and pedestrian traffic. The ADA Transition Plan outlines a phased approach, addressing high-priority issues immediately and setting a long-term path toward comprehensive ADA compliance.
Using mobile LiDAR technology to survey the City’s sidewalks, curbs, and pedestrian facilities provided precise and efficient data collection, surpassing traditional methods. This 3D mapping technology allowed for faster, more accurate surveys across large areas, significantly reducing time
and labor.
TWM then made the LiDAR data available through a GIS database, ensuring transparency and public access. This initiative fosters collaborative city planning, empowering the community to engage with infrastructure projects in real-time. By combining LiDAR and GIS, TWM provided a way for the City to visualize noncompliant pedestrian facilities, prioritize upgrades in high-traffic areas, and focus on locations that would benefit residents most, including those near essential buildings and the residences of the seven representative plaintiffs in the Consent Decree.
