DESIGN DRIVERS

For our design proposal we want to base our development around the concept of the watershed. The Watershed has become our main restraint in order of conveying our density plan. Watersheds act as a drainage divide. We look to structure our development based around these divisions. We have broken our catchment into three main densities of high, medium and low.

NO RU

Within our proposal we look to place areas of high density along the ridgelines of each catchment. With high density areas having higher impermeable surface area there will be greater run off in these areas. As we move down our density catchments from medium to low density the impermeable surface areawill become less. With less runoff down towards the coast we can attempt to mimicthe natural structure of the catchment. With less run off, there is less impact upon the sensitive ecologies that live around our coastline boundaries.

FF

HIGH DENSITY

The Watersheds allow us to structure our design proposal as we can design for each particular catchment. The Watershed creates a mosaic of cells within our site. This allows us to work upon each cell individually and to apply our theory to the constraints of that cell.

CONTEXT- SITE

In this map shows the constraints of our site. Our site sits within the western side of Karaka and backs onto the sites extent. This area became of interest to us largely because of its diversity. The site holds much attraction through it views as well as ecological and topographical advantages. Our site works in the constraints of a singular Watershed along the Western side of Karaka. Our site would also look to hold all three types of densities, zoning from high, medium and low. A riparian corridor runs through the middle of our site and works its way up towards the main road. This was an attraction to choosing our site as we look to implement a coastal boardwalk around riparian corridor. The objective behind our design is to reduce run off affect to the coastline. By having areas of most impermeable surface area located at the top of our site areas (located in high density zones) our areas of lower impermeable surface area would be located down towards the coast. We wanted to structure our design around the natural flow of the catchment to limit the amount of runoff.

DENSITY BREAK DOWN

High density zones along the ridgelines this also gives benefits for our view shafts. Areas based along the ridgelines gain greater views of the water ways however areas closer to the shoreline have are allocated with larger land plots. The High Density zone coincides with the existing roads on the site with roads situated along the ridgelines of our catchments. This will create our main artery of transport. This will allow us to develop our high density primarily and then branching out from these main areas into our areas of lower density. Along our main road there will be commercial and retail shops. Set back from the road will be our residential development. This medium density is distinguished by larger land blocks than seen in the high density zones. Throughout this density will be more Individual housing development in comparison to the housing complexes within the high zone. This mid density has less impermeable surface as the catchment works its way to the coastline. The Mid Density acts as a bridging between the high and low as it shifts from commercial and dense residential into more self-sustained living.

LOW

MEDIUM

HIGH

Within our Low Density zone this will be the area with the greatest sized land plots. This area has greater access to the coast and larger public open spaces. The low density area is a hybrid development with both agriculture and living. Having a low density zone encroaching upon the coastal boundary we want to make this area with the least impacting development. Having lower zone of non-impermeable surface will reduce the run off within the site. Within our Low Density there will be areas of public green pockets located around the coast. These areas will be linked back to the central hub of North and West Karaka. Through a series of green corridors access to these public parks can be filtered through our three zones of density.

SLOPE

This mapping shows the slope of our site greater than 15 degrees. These indicate all the slopes too great to be built upon. All the areas represented in the red will need to be vegetated to avoid surface run off as well as any further degradation to the slope. Through this mapping we understand there are a small amount of steep slopes in the area. Karaka is compiled mostly of gentle undulations which gives testament to its primary use of agricultural land use. Most of these slopes follow areas of hydrology, such as coastline and rivers. In this instance these areas will also be re-vegetated due to riparian corridors as well as coastal buffers. The black linear lines on the map shows my zoning of high medium and low development proposed in project one.

HYDROLOGY

This map shows tributaries within our allocated site within Karaka. The thicker blue lines are our riparian corridors. These areas will be re-vegetated with a 15metre buffer. The purpose of these corridors are for soil conservation of the river banks but can hold extremely diverse ecologies. Throughout our mapping shows both the water sub-catchments and the riparian corridors. This helps towards our understanding of where your water flows are concentrated and where the ridgelines within my site reside. Areas around our coastline will also be buffered. These are sensitive areas due to the ecologies based around this boundary. These areas can be buffered to avoid run off as well as a coastal buffer for possible sea level rise.

ASPECT

This map shows all the southern facing slopes within my site. These areas are less desirable for development due to sunlight being limited in this area. With the site remaining relatively flat and with gentle rolling slopes certain southern facing slope will be little concern for development. However with larger clusters of southern facing slopes these areas should be taken in account to limited development.

FLOW DIRECTION

This map is a diagrammatic take on water flow directions within my site. The arrows indicate the direction of flow of water within sub-catchments. This give an indication to me the areas of pooling within the site as well as where valleys fall in context to the site topography. This will help indicate where I should place my storm water treatment facility as areas with a high concentration of water catchment would be of priority.

VIEWPOINTS OF SITE

This map shows the areas visible from thedark blue dot. The dark blue dot is located along the main road running down Karaka West. Judging by the blue areas the view shaft allows us to see areas of higher land and areas which have plateau. Where the land falls away into valleys the view shaft is then limited within these areas. From further investigation from site visits we noticed that along this main road allows a view shaft out into the harbour. Areas located up by this road run along the ridgelines of our site.

VIEWPOINTS OF SITE

This map shows the areas visible from the red dot. The red dot is located in relatively close context to the coast in Karaka West. Judging by the red areas the view shaft allows us to see areas of higher land looking back up towards the main road network. Where the land falls away into valleys the view shaft is then limited within these areas. Areas closer to the coast can not be visable from this area as the land falls away quite abruptly. This area would still hold good view out to the harbour due to its porximity to the coast.

CELL DEVELOPMENT

After observing my site analysis I began to layer all constraint information on top of one another. Taking into account hydrology patterns, steep slopes, southern facing slopes as well as view shafts I began to isolate separate cells of development. These zones begin to develop the structure of my development and can isolate it into certain areas. The cell allows me to break up the site and challenge each zone as a separate site and how that zone will be structured due to the constraints it has pressured upon it. These cells are also strucutred around my key idea of the water catchment. Each particular cell can be reconfigured to certain restraints which my design driver implements.

PROPOSED ROADS

This map shows the implementing of my roads within the site. The existing road running through West Karaka will act as my main road. Commercial shops will line this street with an element of residential dwelling. I wanted the roads structure to mimic that of the cell. The road network uses a block system which helps reach all parts of the cell. Cul-de-sacs created within some of the cells to help locate housing into the central points of the cell development. The northern cells intersect the main road to create a new intersection. In contrast to the circuit design of the roads an addition straight road runs from this main road intersection down to the coast.

RE-VEGETATED LAND

This map shows the proposed green areas for my site. Through looking at both the hydrology map and steep slope we begin to gain an understanding for the areas which are going to be re-vegetated. These areas will mostly be revegetated with native or indigenous forest which will link with smaller patches of forest located aorund Karaka. With the site having an area of riparian corridor this will be re-vegetated and integrated into my design. Along this green corridor I look to propose a public walkway which intersects the top of my high density and heads back down to the coast. I look to proposed central green zones within each of my density cells. These zones will all link up into the riparian corridor walkway. This will create access for all three zones (high, medium and low) access to the riparian walkway and a link to the coast. Areas of steep slopes and coastal buffers will be implemented with further vegetation. This is to avoid deterioration to the slope and also to aid runoff along the coast.

There will also pedestrian aspect to the roads with footpaths for traffic flow. The coastal boardwalk will act solely for pedestrians. No car access will be allowed through this area. Cyclists will be allowed access to this boardwalk. In turn to allowing cyclists access along the boardwalk the boardwalk will have to be expanded to roughly 4metres.

PARKING DIAGRAM

This shows the allocated parking areas which surround my site. Parking lines the street throughout the site and there will also be house hold parking within each site block. Around areas of my high density zones there will be areas solely allocated to parking zones which back onto the apartment blocks running along the main road. These areas will help accommodate area of high residential parking as well as people looking to use the commercial hub along the main road. I have also allocated an area of parking along the coast. Along the coastline there will be an area of commercial blocks running along the waterfront area. As this will become an area of attraction I have situated extra parking down along this zone to accommodate for a further influx of people.

HYDROLOGY AND STORM WATER

This map shows the storm water and hydrology within my site. The riparian corridors and main arterial storm water follow similar paths. The dotted red lines help connect with the intersection on the roadways. I look to propose a storm water catchment zone between my lower and medium density zones on the northern side of the site. This is an area which a lot of my main zones filter into and an area of pooling

MASTER PLAN This shows the completed master plan for my housing development in Karaka. Throughout the process of Design I wanted to create an approach which structured logic around the workings of a water catchment. I wanted to reduce as much impact onto the coast as possible through runoff imposed by housing developments. Although I wanted to reduce coastal impact I did not want to deter people from the coast. I wanted to create various design interventions to bring people back to the coast. Coastal boardwalks and public gardens which intertwine routes to the coast help achieve this.
