Crossed by L'Orbiquet and La Touques, the floods of the city of Lisieux have always been a plague returning regularly in its history. Between 1875 and 1887, important work on La Touques will be done to protect the city from floods. This will lead to various enlargements with the purchase of strips of land from several residents, the reduction of the garden of the former sub-prefecture on Saint-Dominique Island (current location of the Mosaïc equipment), widening and raising of the bridges. and, what remains most visible, the construction of several sluices.
Many mills have been built along the rivers. In many cases, a dam with valves existed nearby to divert a portion of the stream flow to the mill wheel or plant turbine. In the basin of Touques, factories and mills having ceased their activity, most of the dams have no more function, except the approval. However, this requires vigilance because a lack of maintenance of the watercourse and the reinforcement of the sluices can increase the floods. In addition, fish migration is disrupted, the stream sinks and the environment degrades. When the stakes are high, the construction of the structure or its removal, in consultation with its owner, is then necessary.
The Fleuriot Textile Factory was established in 1864 by Mery Samson, Beau Samson and Fleuriot, replacing their factory on St. Anne Street, which was burned that same year. The factory then included wool degreasing workshop, finishing room, spinning, carding, crushing workshop, dyeing, weaving and shops. The spinning mill was rebuilt in 1866, after a fire. A soap factory, a scrapping workshop, shops and housing were built around 1875. The establishment was acquired in 1910 by Jean and Chrétien Mommers, tenants and operators of another factory, rue d'Orival. Workshops are rebuilt. The Mommers factory, partially burned down in 1923, ceases to operate around 1964. The buildings have since been divided into independent workshops. They produced printed sheets, sheets and plain clothes and woven felt. It employed up to 500 workers in 1927. This factory was operated until 1921 by the SNC and then by SA Jean and Chrétien Mommers.
