Philadelphia’s City Council is considering installing rubber sidewalks, KYW1060 reports. City Councilman at large Jim Kenney recently toured Chicago to see its environmentally-friendly city projects.

According to the Philadelphia Daily News, Kenney and fellow Councilman Frank DiCicco introduced a resolution calling for hearings on the long-term benefits of replacing cement sidewalks with rubber sidewalks.

Last year, Chicago launched a 12-month pilot program to determine whether rubber sidewalks could hold up to foot traffic and Chicago’s weather. Chicago is testing a product from California-based Rubbersidewalks.

Rubber sidewalks have also been installed in Washington, according to Kenney.
