Coastal erosion management of the Kapiti Coast Beach Environment
The Kapiti Coast lies at around 41°S 175°NAddress:, North to South the Kapiti Coast goes from Peka Peka at Te Hapua Road towards Paekakariki to just at the beginning of the Centennial Highway. And from west to east from the western edge of Kapiti Island to Reikorangi in the Tararua foothills. This is around 50km north of the capital Wellington. Along this coastline wave and aeolian action is causing coastal erosion, prominently from Paekakariki to the Waikanae River mouth. The Kapiti Coast District Council (KCDC) and independent groups have put in measures to stop this erosion. The measures include, Vegetation planting, seawalls, rock revetment, dune restoration and beach re-nourishment. Below is a diagram showing areas on the Kapiti Coast where measures have been taken out. (Fig. #1) Currently the recent dune restoration along Paraparaumu Beach is doing great, however the seawall along Raumati to Raumati South’s coast line is failing and rock revetment that has been out in place to improve the seawall’s performance is failing too.

Support Coastal Erosion Management-
Kapiti Coast District Council:
The Kapiti Coast District Council (KCDC) supports coastal erosion management as it is a “public reserve under the control of the Wellington Regional Council from Mean High Water Spring Tide Mark seaward”(1). The KCDC has put in measures to protect the beach from eroding; these include a seawall in Raumati South which stretches from Marine Gardens to Queen Elizabeth Park. This was installed in 1977(2) after the September 1976 storm which created highly destructive waves in which the Raumati South coastline was severely eroded. This seawall absorbs and deflects the wave’s energy and stops erosion. Residents in this area pay extra rates to pay for the seawall to be maintained. In 2007 dune restoration was carried out along the Paraparaumu Beach coastline where dunes were restored, shaped and vegetation planted on. The KCDC protects the beaches as it is stated in the Resource Management Act ’91 policy (3).
Manly Street Residents:
Manly St Residents support coastal erosion management as they are one of the areas along the Kapiti Coast that is heavily affected by coastal erosion. They want the KCDC to take action on their problems caused by coastal erosion. These people want the KCDC to save the beaches as it affects their properties and houses. Manly St beach front property owners all agree that there should be measures put in place to stop erosion and their properties be safe. Many Manly St residents support coastal erosion management as the KCDC have already done work to protect their houses. In June, 2003 the KCDC carried out dune restoration along five private Manly St properties. Marilyn Glennon said “It looks so green and well shaped. The whole beach should look beautiful like this”(9). However within this group Susan Walker, who owns a beach front property on Manly St, thinks that the KCDC should leave the beach alone and let nature that its course, despite her property and house being at risk of being washed into the sea.(4)
Oppose Coastal Erosion Management-
Some local residents oppose coastal erosion management. This is because they have to pay higher rates to pay for measures to stop erosion. For example people that live in Raumati South have to pay higher rates to maintain the seawall, $65,000 annually (5), despite not even being affected by the seawall. And because of this it means people oppose coast erosion management measures and let nature run its course. Miss Meikle said in a forum in class that “Personally I do not like paying extra rates to protect other people’s properties”. Most...
