<strong>Anchor</strong> <strong>Environmental</strong><br />

Prestedge Retief Dresner Wijnberg (PRDW) have been monitoring <strong>the</strong> state <strong>of</strong> <strong>the</strong> groynes<br />

and beach since dredging was completed in November 2008. Some structural damage became<br />

evident on <strong>the</strong> Nor<strong>the</strong>rn Groyne (<strong>the</strong> second one constructed), with some <strong>of</strong> <strong>the</strong> bags suffering from<br />

wave damage (Anton Vonk, PRDW <strong>2010</strong> pers. comm.). These need to be repaired to ensure no<br />

fur<strong>the</strong>r deterioration, and await budget from <strong>the</strong> municipality (Andrew McCarthy, PRDW 2011 pers.<br />

comm.). The sou<strong>the</strong>rn end Groyne is reported to be working well and is retaining material. A<br />

bathymetric survey was conducted at <strong>the</strong> end <strong>of</strong> <strong>the</strong> project and a second bathymetric survey is<br />

pending. Once <strong>the</strong> necessary budget has been approved for <strong>the</strong> pending repair work and survey, a<br />

final report will be compiled which will mark <strong>the</strong> end <strong>of</strong> <strong>the</strong> monitoring period for this project<br />
