This series consists of aperture cards dating from about 1980 containing plats of additions to the City of La Crosse drawn by the City of La Crosse’s Engineering Department. The cards were filmed from the city engineering department’s plat books and are therefore arranged by volume and page. An alphabetical index by name of the addition has been provided in the container listing.

In addition to the plats there is another set of aperture cards showing house numbers for most of the City of La Crosse. The street boundaries of the specific area covered is indicated on each card.
