Everyone in Piha is aware of the convergence of the two streams, the Wekatahi and the Marawhara, in the north beach and the dune erosion that was accelerated by the storms and high tides in December. Also there seems to be two opposing stances by various people in the community.
Piha Coastcare and their local supporters have been lobbying Auckland Council to have the streams separated by mechanical means and the dunes restored and/or reshaped. Similarly, the Waitakere Ranges Protection Society and many other locals support leaving the streams and dunes for nature to take it’s course, unless erosion threatens the road infrastructure.
In December the Piha R&R, and the two organisations mentioned above, met with Auckland Council and Auckland Transport representatives, including environmental and coastal engineering specialists. The specialists presented survey reports detailing the dune cross section profiles from the sea to the road at a number of points beginning south of the streams and ending close to the Les Waygood Park. At that meeting it was agreed that a “trigger point”, agreed by all parties, should be established to determine a point at which the Council would begin the process of bringing machinery on to the beach to move sand as necessary to protect the road infrastructure. It was agreed by all parties that the trigger point could not be established without more information and that a decision should be made in May 2012. By that time three more surveys would have been completed, (January, February and March,) for a total of four, when a consensus decision should be more easily reached. The trigger point noted on the Auckland Council information below is not an agreed position, but an interim position proposed by Council specialists at the December meeting.
In the meantime Auckland Council has applied for consent to enter and work on the beach with heavy machinery during summer months, (existing consents forbids work on the beach between approximately Labour Weekend and Easter,) and since the late December dune erosion, has been lobbied by some for work to be undertaken immediately.
We have received communication and reports, see below, from Auckland Council regarding this situation, in which they propose another meeting in late February. Your opinion and input is important.
