Roches Beach Access Options Community Consultation

Feedback on the Roches Beach Access Options has now closed. 

Thank you for the feedback provided on the Roches Beach Options. C ouncil staff are reviewing the feedback and options. It is expected the results of the community feedback and options wil lbe considered by aldermen in January 2018 for a decision at a February 2018 Council Meeting.

  

Due to concerns expressed from some members of the community about access to Roches Beach, Council identified options to re-install beach access near the eastern end of the canal.

Following a public information session on Wednesday 6 December, Council invited members of the community to provide feedback on these options.

Council has identified three beach access options near the canal (previous access) for kayaks, canoes and dinghies (up to 5m). See more information below on these options.

 

Background/why the decision to raise the dunes at Roches Beach

Roches Beach has been identified as the most vulnerable site in Tasmania to coastal erosion and inundation due to low level dunes and limited sand volume. This area is identified as being at risk of immediate coastal erosion for a present day 1 in 100 year storm event. Erosion of the dune on Roches Beach will result in inundation of the land behind the dune.

Following the storm event in July 2011, Council engaged Water Research Laboratory (University of NSW) to inspect Roches Beach and Cremorne Beach to identify a priority list of works to help remediate the site and protect resident’s properties and infrastructure (Council facilities, NBN, water main, sewer). The site was identified as requiring additional volume and height of dunes.

WRL recommended dune reconstruction as a first priority to avoid immediate erosion and overtopping. The dune reconstruction was to be designed to meet the target dune crest height of 3 metres (Australian Height Datum).

In 2012 Council took action to build the low points in the dunes. Two significant projects were completed to remove low points in the dunes along Roches Beach using large amounts of sand. This work has improved protection of the properties behind the dunes.

In March 2014, Council approved the construction of the proposed sand dune and Disability Discrimination Act (DDA) compliant access at Lauderdale Canal on to Roches Beach.

After concerns from some members of the public regarding the loss of access for kayaks, canoes and dinghies, Council has investigated options to provide beach access for these watercraft near the previous access.

 

Beach Access Options

James Burbury, engineer, was engaged to assess three beach access options near the previous access, as adopted by Council’s Notice of Motion at its meeting of 16 October 2017.  In his assessment of the options he has noted:

 

View a picture of the ‘flexmat’, which is intended to be used for the surface of the beach access.

 

The following options are based on the ramp being at a crest level of RL 3 to be similar to the adjacent dunes.

 

Option 1 – North of Previous Access

The below plan shows a beach access near the existing toilet block.  This toilet block will be demolished for a new toilet block to the South.

The proposed beach access will be surfaced with ‘flexmat’ (concrete block matting) from near the crest of the dune ramping down to the beach.

Pros –   Provides ramp access to the beach at a location where a partial ramp already exists on the car park side.  This option will have least impact on the car park.

             Allows the existing timber ramp to be used by those who prefer this surface.

Cons –   Construction of a hard surface into a mobile dune will require sand nourishment in the future due to erosion on both sides of the beach access.

             Heavy storms may lift the flexmat.

             The location of this ramp is likely to impact on the existing toilet block soakage trenches.

Option 1 - North of Previous Access(282 kb)

 

Option 2 – At the Previous Access

The attached plan shows the removal of the existing timber ramp to install a new ‘flexmat’ surfaced ramp to the beach.

The existing car park needs to be built up in level to ramp up to the dune crest.

Pros –   Provides a central ramp access to the beach.

             This does not depend on the toilet block demolition/construction.

Cons –   Construction of a hard surface into a mobile dune will require sand nourishment in the future due to erosion on both sides of the beach access.

             Heavy storms may lift the flexmat.

             Requires the existing timber ramp to be removed.

             Possible loss of some car parking.

             Is more costly than the North access option as the car park needs to be raised in level.

Option 2 - At the Previous Access(211 kb) 

 

Option 3 – South of Previous Access

The attached plan shows a beach access near the proposed new toilet block, South of the previous access.

The proposed ramp will be surfaced with ‘flexmat’ (concrete block matting) and the existing car park will need to be raised in order to ramp up to near the crest of the dune.

Pros –   Allows the existing timber ramp to be used by those who prefer this surface.

Cons –   Construction of a hard surface into a mobile dune will require sand nourishment in the future due to erosion on both sides of the beach access.

             Heavy storms may lift the flexmat.

             Possible loss of some car parking.

             Is more costly than the North access option as the car park needs to be raised in level.

             Brings vehicle movements closer to pedestrian movements near the toilet.

Option 3 - South of Previous Access(676 kb)
