Countryside Living Development

Fraser Thomas were engaged to provide surveying and engineering services to support a land use consent application for a proposed lifestyle block development comprising 26 large houses on a 92ha site in a rural area of East Auckland.

Geotechnical Investigations were comprehensive, due to the site topography and soils, comprising 36 hand augers, 9 machine bores and 17 test pits. A detailed site investigation was undertaken to check for potential historical contamination. This identified a large area where marine sediments have been placed as fill, some old farm dumps and an old sheep dip.

We undertook earthworks and roading design, including detailed earthworks analysis and plans for 57,000m3 cut and fill over 25ha and preparation of an associated Erosion and Sediment Control Plan. One of the most challenging aspects was the provision of water, wastewater and stormwater services, due to the site being unserviced, its topography and proximity to an estuarine receiving environment.

Each house was provided with multipurpose water tanks for roof rainwater harvesting, providing water for household use, fire fighting water storage and the temporary detention and controlled release of storm flows. A low impact design approach was taken for other stormwater management devices, incorporating stream classification and ecological assessment findings. This included stormwater filter strips and rain gardens for treatment of household runoff and swale treatment/conveyance systems for access roading.

Wastewater management involved detailed soils investigation and soil mapping and preparation of an on-site wastewater disposal constraints plan and supporting report for a TP58 compliant consent proposal. All land use consents have been granted.
