As a result of recent flooding the Council has reviewed its levee system and the Council has determined that its levee, through the Tocumwal Foreshore area, requires both strengthening, removal of trees within the levee and an increase in overall height.
If these issues are not addressed the Tocumwal township is at increased risk of flooding if the levee is either overtopped by floodwater or fails due to lack of structural integrity. The inundation map on the next page indicates the level of township flooding that could be expected in the event of levee failure.
To address these shortcomings the Council will concrete core this 550m section of the levee and then raise its height by up to 400mm. The estimated cost of the works is approx. $200,000 and the Council has received a grant through the Club Grants – Emergency Relief program of $123,000 to assist with the works.
These works are required to be completed by the end of April 2017.
The increase in levee height also requires the levee based to be widened and the Council will focus as much as possible of this on the river side of the levee however some widening will also be required on the town side of the levee which will reduce the amenity of the foreshore area until lawn cover can be restored.
Regrettably, the works will also require some tree removal which is of concern to the Council and undoubtedly the community, however, the Council considers that protection of the community is the highest priority and unfortunately up to 50 trees will require removal.
Completion of the works in the short term will also ensure that works in the foreshore area as proposed by the Tocumwal Foreshore Masterplan (http://www.berriganshire.nsw.gov.au/Portals/0/Docs%20for%20public%20view/2016_09_25_TFM_Final%20Report_1592_%20-%20Compressed.pdf) can also proceed.
