TCDC mitigating beach erosion at Flaxmill Bay
Work is progressing on options to mitigate beach erosion at Flaxmill Bay as part of a wider programme of work to protect the Coromandel coastline.
A combination of king tides and an extreme weather event last July last caused significant erosion at Flaxmill Bay and Cooks Beach, and Thames Coromandel District Council has been discussing appropriate options to address this through a series of community meetings and workshops.
They have a current resource consent application with Waikato Regional Council for a staged rock revetment at Cooks Beach that will transition to a backstop wall and, ultimately, to a soft option (dune plantings) to protect this beach. They are currently finalising the preliminary design drawings for the application, with updates to the beach access and landscaping enhancements.
Once TCDC has these design drawings together they will come back to the community for an update on the project, process and cost to complete this within this financial year (June 2019).
At the same time, TCDC is working on a second resource consent application to build a trial groyne at Flaxmill Bay. The exact location and material for this groyne, which is a low wall extending out from the beach into the sea, is still to be finalised.
All going to plan, construction of the erosion protection works will start before the middle of this year, and construction of the groyne is expected to start before July.
Thames Coromandel District Council’s coastal engineer Jan van der Vliet says environmental changes have raised the community’s awareness of the need for careful management of the coastline and in particular the foreshore.
“We are pleased to be making progress on these two projects to address coastal erosion in Flaxmill Bay and Cooks Beach and we will continue to keep the community updated as we work through the process," Jan says.
