Noord-Holland introduces noise limits for provincial roads

The province of Noord-Holland has introduced noise production ceilings (GPPs) to regulate and limit the growth of traffic noise on provincial roads. These ceilings are designed to prevent noise levels from increasing indefinitely in the future. The province will use 2024 traffic data as a baseline, adding a margin of 1.5 decibels, which the province notes could allow for approximately 40 percent more traffic before the limit is reached.

In addition to these future-facing ceilings, the province is addressing existing noise issues through its 'Actieplan Geluid' (Noise Action Plan). This plan targets buildings, primarily residences, where noise levels from provincial roads exceed 50 decibels. For these areas, the province evaluates potential interventions such as installing quieter asphalt, reducing speed limits, or erecting noise barriers.

Furthermore, the province has designated noise attention areas. For any new construction projects within these zones, developers must investigate if noise levels on facades exceed 50 decibels and, if so, consult with the province to implement mitigation measures. Residents, municipalities, and other stakeholders can submit their feedback on these plans from August 19 until September 30, with final limits expected to be established in December.
