residents express concerns over water turbidity during Construction of narrabeen lagoon Aquatic Boardwalk and Disturbance of Aquatic birds during Black Swan Breeding Season
In March 2018 a community consultation commenced on the proposal to install a boardwalk into the Narrabeen Lagoon. The consultation followed on from a March 2017 Aquatic Boardwalk Design.
'since completion of stage 2b of the Narrabeen Lagoon Trail (NLT) in 2015 the recreational trail has enjoyed high popularity with the community and the Trail is considered a success in promoting a healthy lifestyle while also providing sustainable access to the natural environment.
Council has developed a safe solution for the northern side of the lagoon where the trail is adjacent to the Wakehurst Parkway. This narrow section of trail is a potential hazard for bike riders and pedestrians.
This existing path is in an environmentally sensitive area. The embankment is too unstable to construct a cantilevered structure and would require removal of all vegetation along this part of the riparian zone.'
- Preserves the Aboriginal heritage items on the shore
- Provides a consistent level of service with rest of the NLT
- Resolves safety hazards
- Enables the remediation of the riparian zone (included in the scope of the project)
- Provides a much better experience being well removed from major arterial road.
- Turpentine piles to ensure there is no leaching of harmful chemicals from concrete or treated pine piles into the waterway
- 2.5m width of boardwalk to comply with shared path requirements
- Inbuilt pockets in the boardwalk abutments to provide habitat opportunity
- The alignment and construction methodology has been determined by the current bed of dead seagrass to ensure that living beds of seagrass are protected.
- best practice safety for pedestrians and cyclists
- minimal environmental impact
- diversity of recreation experience on the trail
- aesthetically pleasing outcome from the waterway
- ability for Council to undertake riparian and foreshore revegetation and restoration of the degraded lagoon edge along the Parkway
