karaka
the
site was chosen on the western side of karaka, spanning from urquhart road to the western coastline. an inlet area was included in the chosen site to represent a major theme in the overall design of karaka. This theme was to create a series of large green corridors, which connect the town centre to the coast along the existing ephemeral streams.
there
are four major riparian corridors where the water from this catchment flows into. These are the major determinants of non-buildable area in the site as well as the steep slopes surrounding these corridors and the steep bank which runs parallel to the coastline, about 300m inland
Analysis
the topography plays an important role in determining the suitable location of houses. the low lying areas and gullies should be vegetated whilst the higher areas in between the gullies are suitable for housing.
KEY
hydrology
riparian margin water basin water flow southern aspect steep slope
Most of the land suitable for building is gently sloping and sits reasonably high above sea level. the steep bank parallel to the coast provides an ideal viewing platform for homes in the low density zone, whilst Higher density housing further inland can also benefit from views as it is situated at a higher level. Four different view points are shown in the diagrams to the right. Two are from in the site, two are outside the site. Most of the housing is placed in the red areas there is very little existing vegetation. Most of the land is cultivated open space.

overall zoning of karaka is shown in the diagram to the left, which is to focus the high density housing on the ridgelines of catchments and then make a transition from medium to low density as one moves further out to the coast. This zoning determined the general placement of the housing density within the chosen site (shown in the diagram to the right). MEDIUM DENSITY Existing roads were kept. Additional roads are designed to Legend fit housing within the boundaries created by the contraints Medium Density found in the analysis and to allow good vehical circulation. Transport Links Public Parks
The unsuitable areas for building Green Corridors which include the low lying land close to the coast and the natural gullies, are enclosed in a large revegetated area which includes open space, contructed wetlands, coastal wetland and the riparian corridors. this large greenspace is for recreation and the ecological health of the area. It also creates a connection from the centre of town to the coast.

the Revegetated area consists of four main areas each with their appropriate vegetation types: native bush, open space, coastal wetland and constructed wetlands.

Med density low density
Streets are lined with tree species which differ according to the density zone they are planted in. neighbourhoods are then defined by their associated tree species. There are 8 different neighbourhoods in the site: town main road, 3 High density areas, 2 MEdium Density areas and 2 Low density areas.
