The KAUST perimeter security fence systems pass on the Northern side of 400m wide lagoon between Kaust and Naval lands. As there is no Kaust land available north of the lagoon, the security systems will have to pass through the lagoon which is currently full of mangroves. In accordance with royal decree, these mangroves require to be conserved and thus SAPMT suggests that one of the following be implemented.

1.	Only the crash rated wall be constructed at the northern edge of the lagoon and CCTV cameras be hung on the southern face of the wall, without creating an IDAS zone.
2.	Acquire more land from Navy on the north of the lagoon, and adjust the security corridor within available land providing 2 IDAS zones and 2 Security walls, and eliminating the National Guard patrol road on the outside.

In case none of the above options is considered, and if the security corridor is developed according to the existing Kaust deed,  it is feared that approximately 20,000 square meters of mangroves shall be destroyed. These mangroves have grown abundantly at the shorelines and can not be re-planted or moved further deep into the ocean.
