In March 2011, the Ashfield Council jointly commissioned a traffic study into the Summer Hill Flour Mills redevelopment and the Lewisham Towers development. The independent consultants found that:
- Traffic generation: 1,000 more cars per hour in peak hour
- Density: 680-1,000+ residential units
- Retail: 8,500m2+ including supermarket
- Commercial: 3,800m2+
With the combined generation of 1,000 cars per hour in two directions, the independent report concludes that “this is a significant volume of additional traffic in an area where there are already a number of traffic constraints.” The intersection of Railway Terrace and Old Canterbury Road is noted at being at “full capacity now” with no mitigation measures being suggested.
The independent report concludes that there are a “number of traffic issues” associated with the proposed developments of the Summer Hill Flour Hills and Lewisham Towers.
