SEMAPA

What SEMAPA does

SEMAPA (Société d'Économie Mixte d'Aménagement de la Ville de Paris) is a public urban development agency founded in 1985 and headquartered in Paris. It operates under a formal concession from the City of Paris to manage urban development across approximately 130 hectares in the southeastern districts of Paris, executing seven major projects: Paris Rive Gauche, Paul Bourget, Python Duvernois, Bédier Oudiné, Porte de Montreuil, Bercy Charenton, and Porte de Vincennes. Its core capabilities include project management for public buildings, sustainable development expertise, and circular economy construction practices, with the agency holding three consecutive BBCA Territoire Bas Carbone certifications (2021-2023) and being a signatory of the Charter for Circular Economy Construction.

SEMAPA's business model is structured around long-term concession agreements with the City of Paris, where the agency acts as the principal development operator coordinating public, private, and specialized partners. It engages developers such as Linkcity for real estate and contractors such as Bouygues Bâtiment for construction, while partnering with Vraiment Vraiment and Yes We Camp for temporary urbanism initiatives at the Bédier Oudiné site. The agency also pursues strategic partnerships with infrastructure and climate actors, including GRDF for innovative heating systems in Paul Bourget and Adaptaville (Agence Parisienne du Climat) for climate-adaptation expertise formalized in October 2025. Financing is supported by EMTN bond issuance with Fitch credit ratings.

The agency is constrained by a single-customer dependency on the City of Paris and operates within a fixed geographic mandate. Its strategic positioning emphasizes sustainability credentials, climate adaptation, and circular economy practices as differentiating factors within the public development mandate. Workforce size is reported in the 101-250 band.
