Statement of Effect:
Development plans:
The proposal seeks approval to demolish the existing 11 dwellings on the site and replace them with a new three-storey apartment development containing 14 two-bedroom apartments and 28 on-site car parking spaces.
The proposal includes:
• two ground floor apartments
• six first floor apartments
• six second floor apartments
• lift access
• undercroft and surface parking
• communal open space at the rear of the site
• multiple setback and landscaping variations
The site is affected by the storm surge overlay under Clause 3.7 of the NT Planning Scheme. The application is therefore impact assessable.
The Statement of Effect itself acknowledges that residential uses “should be avoided” within both the Primary and Secondary Storm Surge Areas. However, the report appears to place most weight on finished floor levels, modelled inundation levels and engineering advice, rather than giving detailed discussion to the broader planning warning in Clause 3.7 that residential uses should be avoided in both the PSSA and SSSA.
The report is also internally inconsistent about the actual overlay status of the site.
In Section 1.0 Introduction, the report states the property is:
“partially located within a Primary Storm Surge Area”.
Later, in Section 5.3 Part 3 – Overlays, the report states the site is:
“wholly located within a secondary storm surge area”.
However, later in the same section it states:
“the western portion of the property is impacted by primary storm surge”.
The report does not clearly explain which parts of the site fall within which overlay area.
The report also gives limited discussion to broader planning issues such as:
• evacuation during cyclone events
• emergency access during major storm events
• cumulative residential intensification within coastal hazard areas
• long-term climate and sea level rise implications
• whether further residential intensification within storm surge areas is consistent with the broader intent of Clause 3.7
The Statement of Effect repeatedly frames the proposal as only a modest increase from 11 dwellings to 14 dwellings. However, the proposal represents a much larger intensification of the site in practice through:
• a continuous three-storey apartment form
• extensive undercroft and surface parking
• large hardstand and circulation areas
• multiple setback reductions
• reduced landscaping depth in several areas
• intensified use of a constrained coastal site
The development plans reinforce this.
DA02 Site Plan shows:
• 775.29m² devoted to “Carparking and Driveway”
• only 148.76m² counted as actual landscaped area
• extensive paving and circulation areas across much of the site
The plans also show that the communal open space is located at the rear of the site behind the building and parking areas. Although technically compliant, this may raise questions about whether the communal open space functions as generous landscaped communal space or as space left after the building footprint and parking layout have been resolved.
The proposal also includes several setback and landscaping variations.
The Statement of Effect repeatedly describes these as “minor”. However, the cumulative effect includes:
• reduced front parking setbacks
• reduced landscaping depth
• encroachments into setback areas
• extensive paving and circulation areas
• anti-climb fencing and gates
• roller shutter parking entry doors
• a 2200mm high masonry wall along part of the frontage
The planning report also relies heavily on the argument that nearby properties already contain exposed parking areas and poor landscaping outcomes.
In Section 5.5.3 Clause 5.2.4.4 – Parking Layout, the report states the streetscape already contains:
“reduced setbacks to parking areas with a lack of landscaping.”
This effectively uses existing poor streetscape outcomes as justification for further concessions rather than demonstrating how redevelopment could improve the streetscape character of Progress Drive.
The plans also indicate a strongly car-oriented layout, with 28 parking spaces and 775.29m² devoted to carparking and driveway areas.
The frontage treatment shown on the plans includes:
• roller shutter carpark entry doors
• anti-climb fencing
• gated vehicle access
• a 2200mm high masonry wall
Together these elements give parts of the frontage a harder and more infrastructure-dominated character than the report’s language about improved streetscape interaction may suggest.
The elevations and sections also suggest a larger and more visually substantial built form than the simplified “three-storey apartment building” description initially suggests.
The north and south elevations show a long continuous built form extending across much of the site frontage and side boundaries.
The sections reveal the building elevated over substantial undercroft parking areas, contributing to a bulkier overall appearance and a more infrastructure-dominated ground level.
The plans also suggest limited deep soil landscaping opportunities because much of the site footprint is occupied by paving, parking and building platform areas.
Although the proposal may technically comply with various quantitative requirements, the application raises broader planning questions about:
• continued residential intensification within storm surge affected coastal areas
• increasing dominance of parking and hardstand infrastructure within infill development
• cumulative impacts of multiple “minor” variations
• reduced tropical landscaping character
• and whether technical compliance necessarily results in an appropriate long-term planning outcome for Nightcliff.
• The current Darwin-region storm surge framework largely derives from the SEA 2006 and SEA 2010 storm tide studies together with later mapping refinements and GHD mapping work.

• Those studies relied on sea-level-rise assumptions of approximately:
• 0.3 metres by 2050
• 0.8 metres by 2100
• More recent information suggests sea-level rise in the Darwin region may already be progressing beyond some earlier assumptions underpinning the existing storm surge framework.
• A 2017 CoastAdapt article written by Pam Robinson, former Environment and Climate Change Strategic Planner at the City of Palmerston, stated that sea levels in the Darwin region had already risen by approximately 18 centimetres over the previous 20 years and described this as “one of the highest rates anywhere”.

• The same article referred to projections of a further rise of approximately 24 centimetres by 2050.
• Taken together, those figures suggest sea-level rise in the Darwin region could potentially be tracking closer to approximately 42 centimetres by 2050, compared with the earlier NT planning assumption of approximately 30 centimetres by 2050 embedded within the earlier storm surge framework.
• A 2021 Darwin Harbour study by Arnaud et al. used modelling calibrated against Cyclone Tracy conditions and assessed future storm surge scenarios using projected sea-level-rise allowances of approximately 0.6 metres by 2075 relative to 2020 conditions.

• These issues may be relevant because the Statement of Effect largely treats storm surge as an engineering and floor-height compliance issue, with limited discussion of:
• long-term sea-level rise
• cumulative coastal intensification
• increasing long-term coastal risk exposure
• whether further residential intensification within storm surge affected areas remains appropriate over time
• The Commonwealth Government’s Northern Australia Insurance Premiums Taskforce Final Report (2015) linked cyclone exposure, flooding, storm surge vulnerability and future land-use planning across northern Australia, including Darwin.
https://treasury.gov.au/sites/default/files/2019-03/R2015-002_NAIP_final_report.pdf
• The report recognised that future cyclone losses in northern Australia may increase because of increasing development exposure and highlighted the importance of careful future development planning in hazard-prone coastal areas.
Although the report repeatedly frames the proposal as only an increase from 11 dwellings to 14 dwellings, the actual plans show a much more intensive redevelopment outcome involving a large three-storey apartment form, 28 parking spaces, extensive hardstand and driveway areas, multiple setback and landscaping variations, and reduced deep landscaping opportunities.
The plans suggest a highly vehicle-dominated site layout relative to the scale of the residential development proposed. DA02 identifies approximately 775.29m² devoted to carparking and driveway areas compared with only 148.76m² identified as landscaped area.
The communal open space is located behind the building and parking areas in a relatively narrow rear triangular section of the site, appearing secondary to the parking and circulation functions.
The frontage treatment also appears substantially harder and more defensive than the Statement of Effect suggests, with the plans showing roller shutter doors, fencing systems, anti-climb fencing and a 2200mm high blockwork screen wall extending across much of the frontage.
The proposal also seeks multiple reductions to landscaping and setback requirements. Although these are repeatedly described as “minor” variations within the Statement of Effect, cumulatively they contribute to a more built-form-dominated outcome with reduced deep landscaping around the site perimeter.
The Darwin Mid Suburbs Area Plan supports increased housing diversity and urban infill, but it also states that new development should “respect the character of existing residential areas”.
The cumulative effect of the building bulk, hardstand dominance, parking layout, reduced setbacks, fencing and storm surge context raises legitimate questions about whether the proposal appropriately responds to the existing residential character and long-term coastal planning constraints affecting the site.
For these reasons, PLan requests that the Development Consent Authority refuse the application in its current form due to the unresolved storm surge concerns, increasing long-term coastal risk associated with rising sea levels in the Darwin region, intensity of development on the site, dominance of hardstand and parking areas, reduced landscaping and setbacks, visual bulk, streetscape impacts, and concerns about further residential intensification within a storm surge affected coastal area.
