Committee Comment

1.              Shelley Washington and Tami Woods reported an update from the Cashmere Stream and Port Hills Working Group meeting held on 27 January 2020, notes from the meeting were included in the report.  Regular meetings of the group will be held at the South Library, and will include engagement with the Spreydon-Cashmere Community Board.  Dates for these meetings are to be confirmed and consideration given to whether there is potential to increase membership.  The focus is mainly on the Cashmere Catchment, but with the ability to be developed to the other Port Hills.

3.              The following points were noted from the discussion:

b.             Kevin suggested to look at LIDAR and soil erosion mapping information to help with the rainy day inventory.

c.              The Compliance priority recommendation to CCC needed to be more specific than what was included in the agenda papers to clarify what the Zone Committee was seeking.

·         carrying out building inspections;

·         processing consents with Erosion and Sediment Control Plans; and

·         deciding on consents to be prioritised for monitoring.


b.         That the Christchurch City Council supports the range of issues and actions being further investigated by the Zone Committee Working Group around improving erosion control management and training.

c.         That the Three Waters and Environment Committee and Community Boards invite Councillors and Board members to join the Zone Committee Working Group on a ‘rainy day inventory’, where the Committee will ground truth sources of sediment and identify steps within a catchment to address site specific issues.

d.         That Christchurch City Council consider creating a short and engaging video for the community about land drainage work being undertaken in Cashmere Stream and down the Ōpāwaho Heathcote River to alleviate flooding, reduce sediment, increase biodiversity, mahinga kai and recreational activities.

e.         That the Council lead by example when carrying out Council earthworks activities and management of Council properties that have an effect on the Cashmere Stream, and the Port Hill catchments that drain into the Cashmere Stream.
