Roseville’s growing apartment pipeline is raising questions about local road capacity as a proposed nine-to-ten-storey development near the railway station progresses through the NSW planning system.

The mixed-use proposal at 1–3 Clanville Road, 75 Hill Street and 2–4 Oliver Road would replace existing houses with apartments, including affordable housing. Now at the Response to Submissions stage, the project has attracted 78 public submissions covering building height, traffic, pedestrian safety, tree removal and construction impacts.
Several residents have questioned whether traffic assessments adequately account for other apartment developments nearby. Their concerns focus on Hill Street, Clanville Road, Shirley Road and connections to the Pacific Highway, where existing commuter and residential traffic already compete for road space.
The concerns extend beyond one proposal. A residential development at 16–24 Lord Street and 21–27 Roseville Avenue received state approval in May 2026, while another at Larkin Street and Pockley Avenue was approved in February.
Both approvals add to Roseville’s housing pipeline, although construction start dates have not been established. Their locations and access arrangements differ, making the assumptions used in individual traffic assessments an important part of the broader planning picture.
Clanville submissions raise wider traffic concerns
Published submissions on the Clanville proposal question how additional vehicles and construction trucks would affect nearby streets, particularly where residential roads meet the Pacific Highway.
One submission identifies the approved Lord Street development, a possible project at 5–7 Clanville Road and other nearby proposals when raising concerns about overlapping construction activity.
Residents have also challenged the proposed building scale, landscaping and heritage impacts. The applicant has lodged its Response to Submissions, although the publicly accessible project summary does not establish whether the design or traffic arrangements have changed.
The Clanville development remains under assessment as of press time.
Council studies identify possible road improvements
Ku-ring-gai Council had already begun examining Roseville’s wider transport network before the latest Clanville application reached public exhibition.
Its December 2024 performance report recorded work on a transport network model for the Roseville station precinct. Potential improvements included additional northbound capacity on the Pacific Highway, a dedicated right-turn lane into Maclaurin Parade, cycling facilities and upgrades to local streets.
By June 2025, council had also identified possible treatments along Hill Street to improve pedestrian safety and amenity. The reports do not establish that those works have been funded or constructed.
Earlier modelling did not cover council’s preferred housing scenario
In a parliamentary response received on 1 May 2025, Transport for NSW confirmed it had not specifically modelled the traffic effects of Ku-ring-gai Council’s preferred high-density development scenario 3b.
At the time, council consultants were preparing transport impact assessments for Roseville, Lindfield, Killara and Gordon, examining existing conditions and alternative housing scenarios.
The response predates the NSW Government’s adoption of Ku-ring-gai’s revised station-area planning controls in November 2025. The final status of the council assessments, including whether they incorporate Roseville’s latest development approvals, has not been independently established.
Planning rules also vary between projects. Applications lodged before 13 June 2025 may remain subject to earlier development controls under transitional arrangements, rather than the framework adopted later that year.

Combined impacts remain under examination
The Clanville application is awaiting further assessment, while the Lord Street and Larkin Street developments already hold consent.
Council’s earlier studies show that broader transport planning was underway, but the available records examined for this article do not establish how the latest combination of approved and proposed apartments has been accounted for.
