An exciting new housing development creating a broad range of housing options to meet community needs.
Kenepuru Landing is an exciting new suburban housing development located close to Porirua City Centre. The 42-hectare site is being developed by Carrus in partnership with Ngāti Toa.
The developers’ shared goal is to create a broad range of housing typologies at varied densities to suit present market demands, and to allow for the greatest possible appeal to a broad range of buyers. To increase this appeal, the developers required architecturally designed streetscapes to provide a sense of identity for the new neighbourhood.
The developers have also set out to supplement connections to natural landscapes nearby - including Rangituhi/
Colonial Knob Scenic Reserve and Te Awarua-o-Porirua (Porirua Harbour) - with the suburb’s own reserves and play areas. The final piece of the development planning jigsaw was to incorporate multimodal transport links to the local railway line, arterial road routes, recreational facilities and Porirua City Centre.
To help Carrus and Ngāti Toa deliver this ambitious project, Calibre Built Environment provided a masterplan for all six proposed stages of development with roads, park and lot layouts, and a complete earthworks design. The earthworks design was developed in the early stages of the project to ensure a cohesive urban landscape for the development as a whole.
Our team used Light Detection and Ranging (LIDAR) survey technology for the earthworks design. This approach
significantly reduced the up-front survey costs without compromising design accuracy or estimations of earth-working costs.
Perhaps one of the biggest successes that our team delivered for our client was a clear and precise three stage plan for managing stormwater issues. Our stormwater management approach encompassed:
- Stage 1: including a combination of raingardens and stormwater attenuation ponds which together achieve the client’s attenuation, treatment and residential amenity goals.
- Stage 2: including the delivery of in-house hydrological stormwater modelling services, which eliminated the need for an expensive external consultant. This approach has resulted in significant long-run cost savings for the client and allows the ownership and sharing of model data within the project team.
- Stage 3: wetland design which delivers a cost-effective solution to the client’s attenuation and water quality objectives while also maximising amenity for residents.
