12.3.1 Soil Conservation

<< Previous 


 Next >>

The existing schemes are documented in the Asset Management Plans. An asset management strategy also exists for the Whakamaru works. The level of service and associated justification has been agreed with the community and affected landowners.

The requirement for new works has been identified through the estimation process for soil conservation discussed in section 8. The emphasis for soil conservation within this zone is on the riparian areas based on the pattern of erosion present, and the distribution of existing protection. Specific catchments identified for additional work include the Tahunaatara and Waiotapu catchments, and those streams draining from the southern side of Lake Whakamaru.

Field surveys have identified a further 156 km of waterways either actively eroding or with high erosion potential.

It is proposed that 113 km and 222 km of bank lengths respectively for the Whakamaru and Upper Waikato subcommittee areas be treated for riparian erosion to achieve the desired sediment reduction. This riparian length is an estimation of the primary areas at risk which were not included in either of the existing schemes.

The liaison subcommittees have agreed with these planning assumptions.
