The canals are roughly bounded by Eastern Court on the east, Court A on the south, Strongs Drive on the west, and Court E on the north. There are four east-west canals (Carroll Canal, Linnie Canal, Howland Canal, and Sherman Canal) and two north-south canals (Eastern Canal and Grand Canal). The beautifully lit canals with gondoliers and arched bridges drew widespread publicity and helped sell lots in the development.
However, as the automobile gained in popularity, the canals were viewed by many as outdated, and the bulk of the canals were filled in 1929 to create roads. By 1940, the remaining canals had fallen into disrepair, and the sidewalks were condemned by the city. The canal district remained in poor condition for more than 40 years, as numerous proposals to renovate the canals failed due to lack of funding, environmental concerns, and disputes as to who should bear the financial responsibility. The canals were finally renovated in 1992, with the canals being drained and new sidewalks and walls being built. The canals re-opened in 1993 and have become a desirable and expensive residential section of the city.
The residential district surrounding the remaining canals was listed on the National Register of Historic Places in 1982. However, in recent years, there has been extensive renovation work on many of the old houses, and many large, modern houses have been built.
