Agence Thierry Maytraud (ATM)

What Agence Thierry Maytraud (ATM) does

ATM (Agence Thierry Maytraud) is a French multidisciplinary urban planning and water management consultancy founded in 2011 by urbanist-hydrologist Thierry Maytraud. The firm combines urban hydrology, landscape architecture, and geographic urban studies within a single practice, serving French public-sector clients — municipal governments (collectivités), intercommunal structures (EPCI), metropolitan authorities, and public development agencies (aménageurs). Following Thierry Maytraud's death in June 2022, the firm continues to operate under the direction of Camille Auvray (Directrice d'agence) and the presidency of Flora Maytraud, with a team of approximately 15 professionals spanning urban hydrology, hydromorphology, urban engineering, landscape architecture, geography, architecture, and urban planning.

The firm's service portfolio is structured around three integrated offerings: maîtrise d'œuvre d'espaces publics (public space master planning), assistance à maîtrise d'ouvrage (AMO, project owner advisory), and prospective/strategic territorial studies. Core technical competencies include urban stormwater management, soil de-sealing, open-sky alternative drainage techniques, aquatic environment restoration, and Loi sur l'Eau regulatory submissions. Technical infrastructure is conventional for a French design consultancy — AutoCAD, Géomensura, QGIS, SketchUp, Adobe CS6, and Microsoft Office 365 — with no proprietary technology platform, AI components, or software products evident in the stack. Operations run from a Paris headquarters (115 boulevard Richard Lenoir, 11th arrondissement) and a secondary office in Arles.

The business model is sales-led professional services targeting the B2G market. Revenue is generated exclusively through project-based mandates won via public tenders (appels d'offres) and negotiated commissions with long-standing clients; fees are not publicly disclosed and vary by project scope. The firm has no external funding, maintains €15,000 share capital as a SASU (Société par Actions Simplifiée Unipersonnelle), and serves clients across at least seven French regions including Île-de-France, Provence-Alpes-Côte d'Azur, Occitanie, Nouvelle-Aquitaine, Grand Est, Hauts-de-France, and Auvergne-Rhône-Alpes. Business development relies on conference participation (Novatech, EauMega, Forum Eaux Pluviales), academic teaching at French grandes écoles (ENSP, ENSA, EIVP, ENPC), and publications in journals such as Le Moniteur, Revue Urbanisme, and TSM.

Core offering

ATM is a multidisciplinary urban planning and water management consultancy that delivers integrated stormwater management, public space design, landscape architecture, urban hydrology studies, and aquatic environment restoration services. It combines urban hydrologists, hydraulic engineers, landscape architects, geographers, and urban planners within a single firm to position rainwater as a design and ecological resource for French public-sector clients (collectivités, metropolitan authorities, and public planning agencies).

Product overview

ATM (Agence Thierry Maytraud) is a multidisciplinary urban planning and water management firm offering integrated services combining urban hydrology, landscape architecture, and geographic city research. The agency operates as a unified practice rather than a platform architecture, providing complementary services including public space master contracting (maîtrise d'œuvre d'espaces publics), contracting authority assistance (AMO), prospective studies and territorial strategies, urban hydrology studies, aquatic environment restoration, and landscape architecture. All services are delivered by a unified team of urban hydrology engineers, hydromorphologists, urban engineers, landscape architects, geographers, architects, and urban planners working within a single structure to ensure cross-disciplinary approaches to water management in urban environments.
