The rise in collective sales, and subsequent proposals to increase the number of dwelling units (DU) at the sites, have spurred URA and LTA to mandate a new traffic feasibility study. The new Pre-Application Feasibility Study (PAFS) is to be submitted to LTA for approval before submitting an Outline Application or Development Application to URA.

The study, done by an experienced traffic consultant, incorporates an assessment of the traffic impact to immediate and critical junctions arising from the redevelopment, identify car-lite initiatives, traffic demand management plans by the developers, and estimated adjustments to the site boundary for road widening where required.

Currently, sites under the 2014 Master Plan zoned as Residential, Residential with Commercial at 1st Storey, and Commercial & Residential are affected by PAFS. But the PAFS may extend to other types of developments in the future, says URA and LTA.

The PAFS will not be required for en-bloc redevelopment proposals that have already been granted before Nov 13. The agencies called for redevelopments to be more sustainable and aligned with the vision of a car-lite city.
