Until 1991, the City of Peoria Township grew as the city of Peoria did, and today, most of what was originally Richwoods Township lies within the 1991 city limits of Peoria, and therefore in the Township of the City of Peoria; however, small parts of Richwoods Township's northern sections remained when the boundaries of the Township of the City of Peoria were fixed in place by law in the 1990s, and these, along with the entire village of Peoria Heights, remain as Richwoods Township.
