An active port to be developed

The Legrand port is part of the HAROPA - Ports de Paris network of ports, which includes a total of 70 public ports in the Île-de-France region. At the municipality of Boulogne-Billancourt scale, the Legrand port is one of the four ports managed by HAROPA - Ports de Paris. It is located on the right bank of the Seine, at Quai Alphonse Le Gallo (RD1), and faces the Saint-Cloud park.

The Legrand port is part of a territory that is undergoing profound changes, with many urban projects using the river to supply or evacuate their construction sites.

Covering an area of 1.3 hectares, the Legrand port is divided into two distinct sectors: a Shared Use Quay (SUQ)* with an area of approximately 4,000 m², and the lower quays with an area of approximately 9,000 m².
* Shared-use quays (SUQs) are waterfront spaces made available to all companies that wish to use the river for the occasional transport of goods and equipment, thus helping reduce the number of trucks on the roads.

The economic relevance of using the river to the detriment of the road lies in the proximity of the transhipment site. It is customary to say that the river has an economic advantage when the shared-use quay is located no more than 3 kilometres from the place of departure of the load. However, other criteria are also taken into account: the quality of road access, traffic congestion, the size of the quay…

 The SUQ of Legrand port is used for the supply or export by inland waterway of construction materials, the disposal of recyclable materials and the transport of large items requiring an infrastructure adapted to exceptional transport. It has been used for major projects in the sector: the development of Île Seguin, the Trapèze joint development zone, the structure of the Cité Musicale and, today, the future Pont de Sèvres station on line 15 of the Grand Paris Express.

The low quays are home to a commercial real estate complex dedicated to boating activities, whose occupancy agreements (public equivalent of lease contracts) expire in autumn 2019 and which will be the subject of a call for tenders open to all project developers who wish to promote the river mode within their activity.

In addition, HAROPA-Ports de Paris wishes to create a passenger port of call at Legrand port, thus creating the first Boulogne-Billancourt port of call to connect the municipality to the Ile-de-France network.
A century of wharf development

Since the beginning of the 20th century, Legrand port has undergone numerous developments:
•    The central part of the port, built at the very beginning of the 20th century, consists of a low quay made of limestone masonry resting on a set of wooden piles
•    The upstream part of the port that hosts the Shared Use Quay is a sheet pile quay built at the end of the Second World War with German steel from "war damage"
 •    The downstream part of the port consists of various shoreline consolidation structures used successively by a shipyard and then by the nautical village of Saint Anne

Today, Legrand port is home to heterogeneous and ageing facilities. Its very irregular topography helps to segment it into several isolated areas. Access to the port for vehicles and pedestrians is not easy, which limits its opening onto the city.
 As the occupancy agreement for the commercial real estate complex expires in autumn 2019, HAROPA - Ports de Paris wishes to use this transitional period to launch a major redevelopment operation for the entire port, in line with its ambition to strengthen the capital region's waterway service and develop ports open to the city.

The redevelopment project

The redevelopment of Legrand port is intended to completely rehabilitate the quays, buildings and water body.
The project aims to:
•    reorganize spaces, routes and pedestrian paths for a better mix of uses;
•    improve pedestrian and vehicle access to the port for greater fluidity and safety of movement;
•    create a new short-term stopover for river passenger services;
•    rehabilitate port facilities for the development of new activities on the water;
•    restructure the existing real estate complex to accommodate renewed economic activities.

This optimization of the general organization of the port and its services will be carried out with a view to urban and landscape integration. It will integrate quality facilities (soils, plantations, furniture) that will encourage the cohabitation of port activities and the promenade along the banks.

Creation of a passenger stopover and a plot (opposite Rue Galiéni) - Development intentions

Creation of a pedestrian side path between the Shared Use Quay and Quai Le Gallo (opposite Avenue du Maréchal Juin) - Development intentions

Planned developments sector by sector

•    The levelling of the wharves will be radically redesigned to restore spatial and visual continuity.
•    The entrance at Rue Gallieni will be modified with the installation of a single, longer and more gentle ramp (1). A plot will be set up below, allowing access to the new passenger stopover (2).
•    (3) A passenger port of call will be created, allowing boats of less than 40 metres to be accommodated for short-term stops.
•    (4) The property complex will be restructured into small lots. Partial demolition will open the view of the Seine from Quai Alphonse Le Gallo. The future occupants will rehabilitate the lots according to their operating constraints, in accordance with a set of specifications imposed by HAROPA - Ports de Paris.

The plot and passenger stopover

•    The quay will be modified to improve its use (6) (modified traffic, new pavements, security).
•    Pedestrian access will evolve: creation of a planted side path (5) permanently accessible to pedestrians and allowing them to reach the other parts of the port from Avenue du Maréchal Juin.
•    The reception of the public will be improved: installation of signage, floor modifications, installation of furniture, quality lighting and planting.
•    The quay may be open to pedestrians outside hours of use by the companies.
