On February 17, 1892 the limits of Capital Township were made co-extensive
with the limits of the City of Springfield. Capital Township is unique among
Townships in Illinois for several reasons. First, Capital Township's boundaries
are coterminous with the City of Springfield. Second, due to the coterminous
relationship with the City of Springfield, all the roads in the Township are
maintained by the Springfield Department of Public Works. Consequently, Capital
Township does not have a road commissioner or levee for road maintenance.
Finally, the Sangamon County Clerk and the Sangamon County Treasurer are ex
officio township officers. The Clerk and the Treasurer function as the Township
Clerk/Assessor and Township Supervisor/Collector respectively.
