RESOURCE MANAGEMENT ACT 1991

Resource Consent applications: CRC203551, CRC203552, CRC203552

The Applicant proposes to construct an earth embankment/flood detention dam across the upper Cashmere Valley, between 79 Shalamar Drive to McVicar Drive - Roundhill Rise intersection, Cashmere, Christchurch, referred to within the application as the Cashmere Valley Dam. The earth embankment/dam is to be constructed for flood detention purposes to reduce flood risk downstream on the Heathcote River corridor back to pre-earthquake levels and improve water quality. The works form part of the Upper Heathcote Storage Scheme.

The legal description of the site which the above applications relate include Lot 501 DP 515978 and Lot 502 DP 515978. Water held by the dam would be on those parcels plus Lot 2 DP 45934 and Lot 1 DP 52720.

 The proposal includes the construction of the earth embankment in and over the bed of Cashmere drain, including the installation of a bypass culvert in the bed of Cashmere drain as part of the dam construction, damming of floodwater, permanent diversion of a section of Cashmere Valley Drain, and associated earthworks for the dam abutment within a high soil erosion risk area.

The following resource consents are being sought to facilitate the proposed activity:

• CRC203551 – A land use consent (s9) for earthworks in an area of High Soil Erosion Risk area for the construction of the dam abutment to tie the dam into an adjacent residential road (Shalamar Drive);
• CRC203552:  A land use consent (s13) for the construction of an earth embankment/dam spanning across the upper Cashmere Valley including the installation of a bypass culvert and associated realignment of Cashmere Valley Drain; and
• CRC203553 – A water permit (s14) for the damming or impounding of flood water within and outside the bed of a river associated with the operation of the Cashmere Valley Dam; and to divert water associated with a permanent re-alignment of the Cashmere Drain via a bypass culvert through the proposed Dam.

A 35 year consent duration is sought for CRC203552 and CRC203553, and a duration of 5 years for CRC203551.
