New plan for upgraded seawall to protect Seven Mile Beach
UPGRADING the buried seawall north of Byron St at Lennox Head will be the primary method of protection for Seven Mile Beach under the amended Coastal Zone Management Plan.
Previously the plan had focused on "artificial nourishment of the beach" (adding sand) as the main line of defence for the coastal village.
But the Office of Environment and Heritage says this option presents problems.
The primary issue is that there is no identified, readily accessible source of sand, and no way to fund this option.
Nourishment will be considered and further investigated in the event of projected sea level rise, OEH said.
In the short to medium term, sand from dredging the Richmond River could be used for amenity enhancement.
Future options could include offshore dredging.
Ballina Shire Council's John Truman said it was the first time OEH had suggested using sand from the Richmond River for nourishment.
"But the likelihood of approvals is another matter; at least this is putting it out on the table," Mr Truman said.
The key priority for Seven Mile Beach is now to "investigate and upgrade existing protection works along the length of the beachfront to a consistent and appropriate engineering standard".
