Blue Mountains – Still Not Another Suburb of Sydney
142–150 Narrow Neck Road, Katoomba

Campaign against HDA fast-track development at Narrow Neck Road, Katoomba

An unprecedented planning shortcut threatens to override critical environmental protections and permanently change the Blue Mountains as we know it.

The NSW Government’s new Housing Delivery Authority (HDA) is being used to fast-track housing developments. For the first time in the Blue Mountains, a developer is seeking approval under this pathway for a large-scale, high-density project at 142–150 Narrow Neck Road, Katoomba - a proposal that far exceeds the limits set in the Local Environmental Plan (LEP) and Development Control Plan (DCP).

The proposal is to rezone land to allow:

This was approved as a State Significant Development and the Department of Planning, Housing and Infrastructure issued its Secretary’s Environmental Assessment Requirements (SEARs) in June 2025. The Environmental Impact Statement (EIS) is currently being prepared but will only be on exhibition for 14 days.

Why this matters:
The Society supports appropriate housing that aligns with local planning rules and the Blue Mountains LEP. This proposal, however, sets a dangerous precedent for our community and our future.

Key concerns include:

This is not just about one development. If the HDA pathway is allowed to proceed in the Blue Mountains, it opens the door for similar high-density projects across our towns - potentially changing the region forever.
