Activity Summary: Flood Protection and Control Works Activity name Activity description Flood Protection and Control Works The Annual Plan 2014/2015 states that Flood Protection and Control Works covers works related to: Flood control schemes River alignment control Land drainage. The Annual Plan 2014/2015 further specifies that land drainage work is undertaken in 28 drainage districts of various sizes, the largest of which is the Raupo Drainage District, and that Council provides administrative and technical support in respect of this activity. Kaihu River Control is administered by the Northland Regional Council (NRC). Activities undertaken to maintain the current capacity of the land drainage network include: Weed spraying Drain clearance Floodgate and outlet maintenance in all districts Floodgate and stopbank maintenance in the Raupo Drainage District. Other stopbank maintenance for remaining districts is discretionary. Flood protection is carried out through various drainage system stopbanks and floodgates. Rivers are also monitored for tidal levels and stormwater levels during weather events and to provide warning of potential flooding. Council also maintains floodgates and monitors floodbank settlement rates. Level of Service Drains have the capacity to enable flood water to recede within three (3) tidal cycles. Stopbanks are 2.6 metres above Mean High Sea Level leaving 0.5 metre above extreme high tide for Raupo area. Raupo Drainage Committee (a formal committee of Council) is in place to perform delegated functions. Page 1 of 9
Activity name Flood Protection and Control Works All flood protection activities outside of the Raupo district are, in general, administered by informal community committees supported to a greater or lesser extent by Council s Land Drainage Co-ordinator according to each committee s request for assistance. Maintenance on privately owned stopbanks is undertaken by the landowner. The Northland Regional Council (NRC) is responsible for catchment management. Research is underway to establish and document current service levels in other areas. Contribution to Community Outcomes Council wants to work with the people in Kaipara to make it a place where it s easy to live. When it s easy, it will be easy to do business here, easy to join in and easy to enjoy nature. Protecting productive land from flood damage is critical to making it easy to do business. Activity delivery model The Council provides a co-ordination role through the Land Drainage Co-ordinator and sets the targeted rates to cover works within each land drainage location which are understood by landowners in each of the land drainage areas. Service level issues: It is currently unclear as to whether current levels of service meet the minimum standard. Any climate change impacts will need to be reflected in levels of service in the future. There is some overlap and confusion as to the respective roles of Kaipara District Council and the Northland Regional Council for land drainage. Risks Climate change. Objections from targeted ratepayers who feel they are not gaining benefits. Landowners making it difficult to access public drains on private land. Funding source and rationale Funding: Targeted rates. Rationale: The main funding source is targeted rates. Flood Protection and Control Works affect certain landowners and they pay for the services provided through targeted rates. Page 2 of 9
