Independent consultants prepared reports on hydrology (water management & flooding issues), urban design, transport and economic feasibility. These formed the basis for the report presented to the Council on 19 March 2012. Please note that the consultants’ reports should be read in conjunction with the Draft Strategic Review Report.
Here’s a summary of the key findings:
Hydrology Study – details the extent of flooding over Warriewood Valley, discusses flood evacuation options and acceptance of the findings by the SES. This report recommends earthworks across various sites to create building platforms and help ensure flood-free development.
Note: Some sites may not be developed until the state government resolves issues concerning flood evacuation criteria.
Urban Design Study – proposed different densities and housing types for undeveloped land. The report identifies possible site amalgamations at specific locations. This report also proposed development options for the Southern Buffer.
Transport Study – based on various development scenarios identified by the urban design report, this report found that most key roads would continue to operate at acceptable levels during peak periods. Some intersections may require work to improve traffic flow for some development scenarios.
Economic Feasibility Study – the recommendation of this report is that for small-lot housing and townhouses, the density should be a minimum of 30 dwellings per hectare to ensure economic viability. The report also found that a single-level shopping centre would be the most viable option for the Southern Buffer.
The Draft Strategic Review Report, taking into account all the consultants’ reports, has recommended a range of housing densities for individual sites. The Report generally recommends densities up to 32 dwellings per hectare, with the exception of one site where the density is 36 dwellings per hectare, if the site is amalgamated. However the rezoning of some sectors is dependent on the resolution of flood evacuation issues.
The Draft Report also puts forward a concept plan for the Southern Buffer area which envisages a range of land uses, including residential, commercial and civic uses.
