Bunnings construction works set to alter creek path

WORK is set to start today on the realignment of Bundamba Creek at the Bunnings construction site at Bundamba.

The works will straighten a section of the 120m stretch that runs on the Bunnings site boundary, shifting the creek further into Rotary Park and away from the Bunnings boundary and include revegetation of the creek banks and retaining walls and new plantings on the Bunnings side.

On the Bunnings side, the plans include a series of pools and shallow areas to reflect natural conditions, and the placement of rocks and wood debris for stabilisation of the creek bank and creation of habitat.

Under the conditions for construction, builders Woollam Constructions must check and monitor for the entry of wildlife and marine creatures daily and appoint a wildlife spotter.

Under the plan, they must halt works if species are in any danger and relocate the wildlife. They must also relocate any trapped aquatic life as the existing channel is dewatered during the construction process.

There have been reported sightings of platypus in Bundamba Creek, along with turtles, native birds and native fish species.

Work started on the $46 million 14,000sq m Bunnings Warehouse in November.

Woollam Constructions applied for design of the creek realignment works on December 18 and Ipswich City Council approved the works on February 12. A Riverine Protection Permit to carry out 1287 cubic metres of excavation and 303 cubic metres of fill along 94m of Bundamba Creek was issued by the Department of Natural Resources in September.

A council spokesman said a pre-start meeting had been held as a condition of the Operational Works permit issued by council.

He said Bunnings was liaising with community-based groups, including Bundamba Secondary College, St Edmund's College, Healthy Waterways and Ipswich Rivers Improvement Trust to ensure long-term revegetation outcomes were achieved.

In their application for the works, Woollam Constructions said the flood modelling design "demonstrated a no worsening of flood levels".

The straightening of the creek bend is designed to improve the stability of the creek banks in the area.

Woollam said the design sought a "balance between ecological function and erosion resistance".

Under the plans, the proposed vegetated corridor width within Rotary Park would be extended beyond the existing community planting area to the top of the bank, increasing the overall extent of the riparian vegetation. The works follow the widening of Bundamba Creek, undertaken in two stages between 2002 and 2006 to improve flood mitigation.

The Ipswich Rivers Improvement Trust project was funded by the Australian Government's then Regional Flood Mitigation Program.
