The western foreshore of the Firth of Thames consists of a low lying mudflat and mangrove covered coastline. Spring tides encroach to close proximity of a formal stopbank that forms the physical boundary between farmed pasture and coastal environment. The existing stopbanks have been formed by dredging the mudflat area within reach of the stopbank, in conjunction with drain spoil from the landward side of the stopbank. The stopbank structure and foundation of soft marine clays consolidate over time, and require bulking and restoring. This will restore protection under conditions of high seas.
As part of the ongoing management of the Miranda-Waitakaruru Foreshore Stopbank system, the following contract works are required.
