The municipality of Steenokkerzeel, Belgium, has filed a formal complaint with the Flemish Environment Inspectorate after Brussels Airport carried out infrastructure works without the required permit. The works involve an expansion of the so-called “run-up zone” near runway 25L, used by aircraft to manoeuvre before take-off.
According to the local authorities, additional hard surfaces were added near the runway, altering water infiltration and increasing flood risks in the area. Mayor Kurt Ryon stated that residents are required to apply for permits even for minor construction works, while the airport allegedly proceeded without authorisation.
Brussels Airport argues that the changes were necessary for operational safety and were carried out under existing regulations. However, the municipality disputes this interpretation and insists that new rules introduced in 2023 require permits for such interventions.
The Flemish Environment Inspectorate is now reviewing the case. The regularisation procedure is ongoing, and possible mitigation measures, including solutions for water infiltration, are being examined.
