Coastal Dune Stabilisation for The Waves, Keurboomstrand

HilLand Environmental, independent Environmental Assessment Practitioners (EAP) have been appointed by The Waves Complex (Home Owners Association (HOA)), to ensure compliance with the regulations contained in the National Environmental Management Act (NEMA, No. 107 of 1998) and the Environmental Impact Assessment Regulations, 2014, as amended, for the proposed dune and erosion protection works for The Waves Complex, Keurboomstrand, Plettenberg Bay. The proposed dune protection works are to be implemented in Erf 412, located in-front (south) of the Waves Complex.

The proposed activity entails the construction of ‘sleeping’ rock revetments and re-establishing the primary dune that has eroded in front of the Waves Complex within as Erf 412 (public open space). The most immediate risk of damage to private property and infrastructure is that of Erf 409 and Erf 411 (forming part of The Waves Complex) and DR 394 and public parking area (east) and, therefore, require immediate protective measures along this section of coastline. The eroded dune has a height of approximately 5 m, which will undermines the building foundations of the immediate erven (north, The Waves Complex), more specifically Erf 409, if the dune height recedes back to a height approximately 4 m.

The proposed sleeping revetment option considered as the preferred alternative within this report, are specifically aimed at the minimisation of the interference with the natural dune system by burying structures (PRDW, 2019 & Hellström & Avierinos, 2011, edited 2018). Extensive rehabilitation will follow the construction and / or installation of the revetment which includes the placement of excavated dune sand back on-top of the revetment, re-vegetation of the dune with indigenous rescued vegetation and the installation of sand fences on top and west of the footprint to assist with stabilisation. The sand fence will additionally allow the natural trapping of sand in the dune zone – enhancing the formation of hummock and fore dunes (Hellström & Avierinos, 2011, edited 2018).

The  Draft Basic Assessment Report (BAR) and associated appendices for the proposed activity are available for 30-day commenting period. In terms of Regulation 4 and 40 of NEMA: EIA Regulations (2014, as amended), you are hereby advised that you have 30 days, from 30 of January 2020, to submit any comments. Please provide us with your comments/concerns relating to the proposed activity during the time frame (30 January 2020 – 02 March 2019) in written format via post, email or fax. Please note that you need to declare your interest in the above matter. Should you have no comments, please send us an email indicating as such.
