serves the parking area in the eastern section while existing houses are served from a discontinuous road along the top of the beach dunes. A feeder road serves lots along the last dune on the western side. Wenela House is also linked into this layout. A backset road is shown at the boundary of the developable area, from where future layout can be served.

Cell T2: Praia Xai-Xai

The existing development provides a framework for the layout of other cells. The basic road layout is not changed, but if the local roads are upgraded, some of the access points on the circle route must be investigated for possible closure as some are not necessary and some join in positions where there may be insufficient sight distance.

Cell T3: Above the existing camp site

This valley will be served by the backset road in future, but access can be provided from the coastal road passing Halley’s Hotel initially. The basic layout is taken from the existing Xai-Xai circle. The collector roads run along the sides of the valley to serve developable areas. The depression in the centre of the valley must be protected for a storm water retention pond. A golf course is proposed to the rear of the cell and can be designed around the backset distributor road and the collector road. The eastern leg of the collector road will not connect on the coastal distributor road due to steep gradients and to discourage traffic along the beach.

Cell T4: Concessions 50/500

Concessions have been allocated over most of this area. Initial access can be provided from the coastal road along the alignment of the collector road until the backset distributor road is constructed. As in Cell T3, only the western leg of the collector road can link to the beach, as the eastern leg ends on a high dune. The collector roads serve the perimeter of the cell to maximise coverage, while local roads will provide access to lots. The area has a number of depressions, which must be protected from storm water retention.

Cell T5: Praia do Alho

The coastal road turns inland through this cell and links with the backset distributor road. This opens the area up and allows collector roads to link up along the road. The area is also already divided into concessions along the beach and further areas for tourism and residential development is made accessible. Some steep gradient will occur on local roads and high dunes must be protected from denudation.

Cell T6: Praia do Chongoene

The topography of the dunes east of the Hotel Chonguene is more broken towards the beach and allows a collector road along the back of the coastal dunes. The beach area must be protected from roads. The area between the road and the beach is made accessible for tourism but is too narrow and sensitive for residential development. Residential development can be located inland of the collector road and local roads can give access to lots.

        Design Standards

Local design standards for district road were used as guidelines. The restrictive topography and sensitive dune environment were taken into account in restricting design standards to the minimum for road safety and functionality.


The district road cross section containing a 6m roadway was used for all the distributors and collector roads. The road reserve width will vary in relation to earthworks (toe-lines of cuts and fills), but should not be less than 25m. The local road cross section was also based on a 6m roadway, but in a 12m-road reserve, with side slopes allowed to enter into the concession where deep cuts and high fills occur. Services, such as water and electricity were assumed to
