Mahere Urutaunga Tapātai-Iti Wai Manawa / Little Shoal Bay Wai Manawa / Little Shoal Bay Mini-Shoreline Adaptation Plan (SAP)

The Wai Manawa / Little Shoal Bay mini-SAP aims to plan for the future of the area's council-owned land and assets in response to the impacts of coastal processes, climate change, erosion and flooding.

Wai Manawa / Little Shoal Bay is a reserve on the north shore of Waitematā Harbour. The Wai Manawa / Little Shoal Bay Mini-Shoreline Adaptation Plan (SAP) covers the shoreline of Wai Manawa / Little Shoal Bay.

As a ‘mini’ SAP, the Wai Manawa / Little Shoal Bay SAP focuses on a single coastal reserve area within the wider Waitematā Harbour West coastal areas.

Wai Manawa / Little Shoal Bay was chosen for a mini shoreline adaptation plan because of:

• its value to iwi and local communities
• its exposure to coastal hazards.

This mini-SAP provides options for managing this part of the coast and reserve in the years to come.

To help us develop a plan for this area, we used:

• coastal hazard data
• climate change forecasts
• values from manu whenua
• input from infrastructure providers
• input from the local community.

• September 2022:
  The Environment and Climate Change Committee approved the mini-SAP.
• August 2022
  Kaipātiki Local Board endorsed the mini-SAP.
• May – June 2022
  We made final recommendations for the mini-SAP and presented these to the Kaipātiki Local Board.
• March – April 2022
  We received and reviewed community feedback.
• 24 January to 16 March 2022:
  Public consultation opened for feedback.

The high-level strategies for the Wai Manawa / Little Shoal Bay mini-SAP were guided by mana whenua principles and wider community engagement.

Once the Waitematā Harbour West SAP is developed, it will include the high-level strategies recommended by the Wai Manawa / Little Shoal Bay mini-SAP.

These strategies include:

• performing additional studies to understand the effects of both saltwater and freshwater
• raising local bunds Barrier, dam or mound used to contain or deflect substances, particularly sediment. Often used to prevent a spill from entering the stormwater system. and upgrading stormwater pipes to reduce car park flooding
• shifting and raising the cricket pitch to the west to preserve recreational spaces and plantings
• installing non-return valves A one-way valve (device) that allows fluid or gas to flow in one direction only. It blocks the flow of fluid or gas in the opposite direction and helps to prevent contamination. on stormwater pipes to reduce flooding from high tides (does not include larger flooding).
• investigating options to reduce flooding through the beach access ramp
• investigating the benefit of existing shoreline interventions.
