A proposal has been lodged to subdivide land at 120 Mona Vale Road and 8 Forest Road in Warriewood into 63 residential lots, prompting strong community objections.
Background and Context
A development application (DA2025/1087) was lodged with NBC for a multi-stage residential subdivision at 120 Mona Vale Road and 8 Forest Road, Warriewood. The project, estimated at $25.6 million, seeks to divide three existing lots into 63 residential lots, one community lot and one residue lot.
Stage 1 involves subdivision works, construction of a public road and bridge via Boundary Street, installation of utilities, stormwater systems, and landscaping. If approved, Stage 2 would require separate applications to build the 63 dwellings.
A similar application was refused by the NSW Land and Environment Court in 2016 due to inadequate vehicular access. The earlier proposal relied on a right of carriageway through Jubilee Avenue, which was deemed insufficient for the traffic generated.
Proposal Details
The current plan aims to overcome previous access issues by constructing new road connections through Boundary Street, linking to the local network. The development forms part of a broader residential project first proposed in 2012 at 8 Forest Road for apartments and townhouses.
Community Concerns
Submissions to Council in late August 2025 raised strong opposition. Residents cited traffic congestion on Mona Vale Road, with claims of long delays during wet weather. Concerns were expressed that local streets, including Jubilee Avenue, are not designed to handle the additional car movements.
Environmental impacts were also highlighted, particularly risks to Narrabeen Creek from sedimentation, runoff, and reduced water quality. Objections noted the potential loss of ecological integrity if a bridge is built through the creek and questioned the project’s compatibility with sustainable development principles.
Other submissions raised issues about overcrowded schools in the catchment, limited public transport capacity, and ongoing disruption from Mona Vale Road upgrade works. Safety concerns were also noted, with residents warning of evacuation risks in emergencies if alternative access routes are not secured.
Next Steps
The proposal is currently awaiting its exhibition period. Once documentation is finalised, the public will be able to make formal submissions through the NBC portal. The development remains subject to further assessment before any approval is granted.
