National Environment Management: Integrated Coastal Management Act, 2008 (Act No. 24 of 2008)NoticesCoastal Management Line for Garden Route National Park in terms of Section 25(1) read with Section 25(5)(a) of the Act5. Methods Applied |
| 5.1 | The following hierarchy of methods were considered when deciding the appropriate location of declaring the GRNP CML: |
| (a) | use of the best scientific information available such as modelled risk scenarios to inform the position of the line, taking into account dynamic coastal processes and flooding; |
| (b) | use of nationally recognised data and information as proxies such as the 5m contour line where accurate flood information for an estuary is not known; |
| (c) | where reliable data is available to e.g. allow for differentiating between the risks associated with floodplains versus gorges along estuaries, modifying the line accordingly; and |
| (d) | use of historic records for the GRNP, including data and local knowledge on areas known to be highly vulnerable and at risk of, or protected from, dynamic coastal processes to inform and modify the position of the CML if required. |
| 5.2 | The following proxies were used when developing the GRNP CML: |
| (a) | the 10m contour line was used by SANParks to show areas at potential risk along the rocky Tsitsikamma coastline as modelled risk scenarios were unavailable; |
| (b) | the 10m contour line was modified at the Storm River Rest Camp based on local knowledge of where areas that are at - or protected from - risk are located due to the nature or orientation of coastline; and |
| (c) | where differing approaches were used for adjacent sections of coast, such as at estuary mouths where a 10m contour proxy was used along the coast and a 5m contour proxy was used along the estuary, a joining line was applied. |
