Coastal Views just received this email from City of Onkaparinga, outlining progress on the stormwater detention basins in John Nicholl Reverse, Aldinga Beach.


Work on the detention basins is complete and now we’re waiting for the grass to grow.

The temporary fencing protecting the new grass will remain in place until approximately mid-July. The fencing does not impede access to the playground.

We will also revisit the site during Spring to complete extra plantings.

Check out some photos of the completed basins in the photo gallery at


The project is jointly funded by the City of Onkaparinga and the Adelaide and Mount Lofty Ranges Natural Resources Management Board.

The detention basins will resolve current and future flooding issues by directing stormwater from the surrounding area into the grassed basins and discharged to the sea via an underground pipe system. The basins will remain dry for the majority of the year and will only hold water for a short time during large rainfall events.

The project has been designed to maximise usable public open space and increase the amenity of the reserve.

Some of the design elements include:

Retain existing Scout facilities, BMX track, footpaths, playground and vegetation (there will be some minor play equipment removals in the reserve however).

Additional planting of gum trees and grasses in the basin.

The layout of the basins and other elements can be viewed on the Landscape Concept Design, located in the document library.
