Shoreline renaturation involves the use of mixed shoreline development techniques that promote vegetation and are of aesthetic, ecological and landscape interest. HAROPA-Port of Rouen thus tested this technique in two sectors in 2010: Jonquay and La Martellerie, which have been ecologically monitored by the Conservatory for Natural Spaces.
The Jonquay's banks
Ecological restoration actions of natural environments and/or hydraulic annexes to the river are being carried out at six sites along the Seine: The small willows in Sahurs, Grande Vase-Petite Vase in Quevillon, the Douillère in La Mailleraye-sur-Seine, L'Angle in Vatteville-la-Rue, La Darse in Lillebonne and Les Ecores in Petiville. The preliminary studies began in 2012. Work on the Sahurs and Lillebonne sites began in 2017.
Ecological restoration of the Lillebonne site
The enhancement of the landscape heritage consists of operations to remove obsolete structures, such as wharves, dolphins, piles, mooring structures and other remains, in order to improve the image of the river and the living environment. Works have thus been removed in the municipalities of Tancarville, Lillebonne and Petiville.
Since 2012, HAROPA - Port of Rouen has been carrying out technical studies to diagnose and propose technical solutions for actions to combat erosion and protect property and people in the Old Port and Barneville-sur-Seine-Le Landin sectors. In 2018, work will begin on the latter sector.
