1 Intention and Scope

1.1 Intention From an urban design perspective, to identify those parts of Porirua City Council’s previously identified Growth Areas that might be suitable for intensification as Medium Density Residential Areas. The recommended areas for intensification are described within the attached Data Analysis Drawings.

1.2 Scope

This study is based on overlay mapping and interpretation of that, and this is based on overlay mapping base data supplied by Porirua City Council.

Areas reviewed are those identified by the Porirua City Growth Strategy, being ‘Compact Regeneration’ and ‘Compact around Public Transport’.

Seismic and tsunami risks have been recognised but not covered in making recommendations. While identified seismic risk areas extend through some of the identified growth areas and tsunami risk areas are close to Mana in particular, determining the implications of that relates to specialist engineering, construction and risk analysis. Key intensification controls include an increase in permitted site coverage from 35% to 45% and in the maximum permitted height from 8 metres to 11 metres, which would permit three rather than the current two storeys. Consideration of character insofar as that is relevant, and as informed by the 2005 Boffa Miskell/McIndoe character analysis.


2 Findings and Discussion

2.1 Porirua East General comments

• This is the area to the east of the city centre and including Porirua East, Ranui Heights, Cannons Creek and Waitangirua, and for simplicity it is referred to as ‘Porirua East’.

• The central corridor area directly accessed from Mungavin and Warspite avenues and extending west-east through the area is well served in most respects, and suitable for intensification.

• Well served by schools with virtually the entire area within 1000m of a school, and most of the areas through the centre within 400m.

• The recommended area for rezoning avoids south facing slopes with a gradient greater than 15°. Many dispersed south-facing areas with a slope greater than 15° between Porirua East and Cannon Creek restricts intensification potential in these otherwise well-located areas.

Figure 1 ‘Porirua East’ Recommended Areas for Rezoning Refer to drawing 1.2b in the attached Data Analysis Drawings.


Local facilities Most of ‘Porirua East’ has good access to local facilities

• Most of the area is within 800m of a Draft Local Commercial Zone except for areas on the south boundary of the area south of Ranui Heights and Cannons Creek, and small area north of and between Porirua East and Cannons Creek.

• Most of the area within 1000m of a school and most of the areas along Mungavin and Warspite Avenues are within 400m of a school.

• The central core of the area along Mungavin and Warspite avenues has access to recreation/playground sporting facilities.

• The library and swimming pool at Cannons Creek are centrally located and while some distance from the city end of Mungavin Avenue and the Whitby End of Warspite Avenue, are readily accessible from all of the wider area.

• Porirua East, Cannons Creek and Waitangirua all have a medical centre.

• There is a marae at Waitnagarua and a Community Hall at Porirua East. These and the library at Cannons Creek provide local community facilities.

Movement infrastructure

• Proximity (500m or less) to a high frequency bus stop is achieved along the central parts of this area relating to Mungavin and Warspite Avenues, but large areas along the northern and southern boundaries of the area do not have this degree of public transport accessibility.

• Parts of Porirua East close to Mungavin Avenue are within 1000m of the Porirua Train Station.

• The northern part of Ranui Heights, Porirua East and Cannons Creek and the whole of Waitangirua are less than 1000m to an off-road shared cycleway.

Topography, aspect and natural areas

• Many dispersed south-facing areas with a slope greater than 15° between Porirua East and Cannon Creek restricts intensification potential in these otherwise well-located areas.

• Draft Significant Natural Areas are identified in gullies and other areas of steeply sloping land. Exclusion of medium density residential development on those is unlikely to have little effect on residential yield, as it is unlikely they could be built on.

Noise, earthquake and tsunami risk

• The SH1 noise corridor impacts on the western boundary of the area, being the western edge of Ranui Heights and Porirua East.

• The area is clear of the GNS 2014 Earthquake Fault Avoidance Zone and the tsunami risk areas identified by the ‘Tsunami Porirua Draft 100 year’ map.


2.2 Kenepuru General comments

• Around three quarters of the identified growth area is suitable for residential intensification subject to conditions. The remainder, located at the western, north-western and central boundaries of the area are compromised by a range of inadequacies including complex, steep, south-facing contours; poor access to recreational facilities; distance from public transport.

• There is no Draft Local Commercial Zone, no playing grounds, community or recreational facilities. These should be planned for and required in the development of this site.

• Kenepuru has very good access to the railway station. The north western half of it is more than 1000m from a railway station, but this notwithstanding, it has railway station access which most of the other areas that might be rezoned for MDR does not.

• Most of the area is reasonable flat, excluding a minor portion at the west and north boundaries which also have the constraint of containing many south facing slopes greater than 15°.

Figure 2 Kenepuru Recommended Areas for Rezoning (at centre of drawing) Refer to drawing 1.2b in the attached Data Analysis Drawings.

Local facilities

• This area is suitably served by service retail. Although none of it is within 800 metres of a ‘Draft Local Commercial Zone’, it is close to the mall and supermarket at the south end of the city centre. Half of this area is within 800m of the City Centre Zone.

• The majority of the site is within 1000m of a school, except for a portion towards the western boundary.

• There are no library, community hall, of swimming pool facilities within the area. However, proximity to the city centre with the full range of


facilities there may compensate for this. This notwithstanding, the area is currently undergoing comprehensive redevelopment and it is possible for these facilities to be provided with that development.

• Kenepuru Hospital provides for medical facilities. Movement infrastructure

• Proximity of 500m or less to high frequency bus stops is limited to the central, southern and eastern two-thirds of the area.

• Much of the area is beyond 500m to high frequency public transport bus stop identified by the Council maps. Should a high frequency bus route be established in the loop around Raiha Street then all of the identified Kenepuru area might be suitable for intensification.

• Around three quarters of the identified growth area is within 1000m of an off-road shared cycleway, with the exception being the north-west corner.


• South facing areas with complex topography associated with the western and northern boundaries of these areas compromise intensification potential there.

• Several dispersed south-facing areas with a slope greater than 15° restrict intensification potential in this otherwise well-located area. One of these identified south-facing areas is within the site of the proposed Summerset retirement village, and that has been accommodated in the proposed development plan.

• A Draft Significant Natural Area has been identified at the Mitchell Stream which passes through the site, and retention of this is a strong positive. The stream is characterised by steep slopes, and its retention will not unnecessarily compromise intensification potential.


• The SH1 noise corridor touches on the eastern boundary of the area at the edge of Kenepuru Drive.

• The GNS 2014 Earthquake Fault Avoidance Zone passes diagonally through the north-west portion of the site. This is through an area which is poorly serviced and for other reasons s not recommended for intensification.

• The area is clear of the tsunami risk areas identified by the ‘Tsunami Porirua Draft 100 year’ map.


2.3 Titahi Bay

General comments

• This, also referred to on the graphic analysis as ‘Titahi Bay’ includes Titahi Bay and Takapuwahia.

• Much of the area of central Titahi Bay is well serviced and offers potential for a large area of high amenity intensification. Takapuwahia also offers limited potential, but this might be increased significantly if the high-frequency bus network were to be routed through this area.

• The hills to the west mean that the area between Takapuwhahia and Titahi Bay is topographically unsuitable for intensification.

• The recommended area for rezoning avoids south facing slopes with a gradient greater than 15°.

Figure 3 ‘Titahi Bay’ Recommended Areas for Rezoning

Refer to drawing 2.2b in the attached Data Analysis Drawings.


Local facilities Both Titahi Bay and Takapuwahia are well-serviced with local facilities. and are suitable for intensification.

• The central portion of Titahi Bay and most of Takapuwahia are within 800m of Draft Local Commercial Zone.

• Titahi Bay has a library, Takapuwahia the marae, and the southern part of Takapuwahai is very close to the library ad swimming pool in the city centre.

• All but the eastern perimeter of Titahi Bay and the northern extremity of Takapuwahia are within 1000m of a school.

• All but relatively limited areas at the northern, eastern and southern boundaries of Titahi Bay, and all of Takapuwahia have reasonable access to sports fields, playgrounds and kickabout areas.

• There are medical centres in both Titahi Bay and Takapuwahia. Movement infrastructure

• Most of Titahi Bay, with the exception of at close to its western boundary is within 500m of a high frequency public transport bus stop as identified by Council.

• Much of Tapapuwahia is beyond 500m to high frequency public transport bus stop identified by the Council maps. Should a high frequency bus route be established around the loop created by Awarua Street and Tapapuwhia Drive then much more of this area might be suitable for intensification.

• Most of Takapuwahia is within 1000m of an off-road shared cycleway.

• These areas are reasonably close to Porirua City Centre and the train station, although are well beyond the identified 1000m distance to the station.


• The large central portion of Titahi Bay and the identified, well serviced area at Takapuwahia and a smaller area further south at Awarua Street’s connection with Titahi Bay Road are flat and offer good potential for more intensive development.

• Draft Significant Natural Areas are identified on steep escarpments to the east of Titahi Bay and will have little impact on development potential, while at the same time offering a high degree of landscape amenity.

• A large area on the hillside to the north-west of Takapuwahia and south-west of Titahi Bay is currently undeveloped, but steeply sloping and also identified as a Draft Significant Natural Area. Most of this area is also un-serviced, being distant from the identified facilities.

• Exclusion of medium density residential development on those is unlikely to have little effect on residential yield, as it is unlikely they could be built on.


• The SH1 noise corridor has no effect on this area, and it is also clear of the GNS 2014 Earthquake Fault Avoidance Zone.

• The tsunami risk areas identified by the ‘Tsunami Porirua Draft 100 year’ map approach properties adjoining Titahi Bay beach but otherwise do not impinge on Titahi Bay.

• A small area of land within Takapuwahia area is identified as having a tsunami risk.


2.4 Mana

General comments

• This is the area including Plimmerton in the north, Mana at the centre, and extending southward towards Papakowhai. For simplicity this is referred to as ‘Mana’.

• Mana (along the Esplanade) and Plimmerton offer flat land that is well serviced and offering significant potential for residential intensification, subject to resolution of traffic and noise issues and verification of tsunami risk.

Figure 4 ‘Mana’ Recommended Areas for Rezoning

Refer to drawing 3.2b in the attached Data Analysis Drawings.


General comments, continued...

• Elevated north-facing areas south of SH1 and overlooking Plimmerton and Plimmerton itself offer significant potential, although the challenges of building on the steep slopes of these elevated areas may restrict much development.

• Paremata is not recommended for medium density intensification because of a combination of:

o Steep, broken topography, including some large areas of south facing steep slopes;

o distance from sports fields, recreation and playgrounds; o separation from Draft Local Commercial Zones, with distance of

less than 800m but a convoluted route and significant contour difference between the draft LCZ and the elevated areas served; and

o absence of local community facilities Local facilities

• Virtually the entirety of the area is within 800m of the Draft Local Commercial Zone, except that proximity from elevated areas at Paremata is compromised by contour difference.

• Sites at the central portion of the Mana Esplanade are beyond 1000m from a primary school, however no part of this is more than 1250m and any dwelling at that distance is equidistant from two primary schools.

• Community halls and medical centres at Plimmerton and Mana serve these local communities. Paremata is distanced from these facilities by the constraints of contours, and the need to cross traffic infrastructure.

• Plimmerton and Mana have good access to local sports fields as well as recreational facilities, but Paremata is less well-served.

• There is no swimming pool here, although residents of Plimmerton and Mana have immediate access to the coastline.

Movement infrastructure Access to movement infrastructure is excellent for the entire area:

• The entire area is well-served by convenient railway access to Porirua and Wellington City beyond, and to the Kapiti Coast, with virtually the entire area within 1000m of a train station.

• Most of the area is served by access of less than 1000m to an off-road shared cycleway.

• While the central area of Mana Esplanade is on SH1 this has the negative effects of congestion and noise. The potential for that to change following Transmission Gully opening might be addressed by others.


• ‘Mana’ has a complex topography with areas of reasonably flat land bounded by the coast and steep hillsides and escarpments.

• Steeply sloping north facing areas at the north end of Mana and overlooking Plimmerton and the sea offer excellent amenity potential, but the complexity and steepness of the topography here may limit potential.

• Draft Significant Natural Areas are identified and in addition to the coastal edge, these are located on the steep escarpments. Exclusion of medium density residential development on those escarpments is unlikely to have little effect on residential yield, as it is unlikely they could be built on.



• The noise corridor related to SH1 and the railway line passes directly through the centre of this area. This might be mitigated by location-specific noise mitigation measures where needed.

• The GNS 2014 Earthquake Fault Avoidance Zone crosses diagonally through the area at the Paremata Bridge. The development implications of this are addressed by others.

• The tsunami risk areas identified by the ‘Tsunami Porirua Draft 100 year’ map touch on the coastal margins of the area, only extending over occupied areas of land immediately north of the Paremata Bridge and some parts of Plimmerton.

• The Mana Esplanade area offers intensification potential subject to management of tsunami risk. Verification of this risk analysis and the implications and extent of the risk is addressed by others.


2.5 Pukerua Bay

General comments

• ‘Recommended area for rezoning recognises the combination of proximity to the noise corridor of SH1 and avoids south facing slopes with a gradient greater than 15°.

• The character of this area is determined by buildings set within an area of intensive planting. Intensification will change that character, although some of that effect would be mitigated by protection of draft ‘Significant Natural Areas’.

Figure 4 Pukerua Bay Recommended Areas for Rezoning

Refer to drawing 4.2b in the attached Data Analysis Drawings. Local facilities Pukerua Bay is characterised by good access to local facilities

• Most of the area is within 800m of the Draft Local Commercial Zone

• Most of the area within 1000m of the school.

• There is a library which provides local community facilities, which can perform a community function, but no identified community hall or marae.

• Central core of the area has access to recreation/playground sporting facilities

• There is no medical centre or swimming pool in Pukerua Bay, however residents will have access to the coastline and beach.


Movement infrastructure Access to movement infrastructure is excellent for the entire area:

• The entire area is well-served by convenient railway access to Porirua and Wellington City beyond, and to the Kapiti Coast, with virtually the entire area within 1000m of the train station.

• Fully served by access of less than 1000m to an off-road shared cycleway.

• While this has direct access to SH1 there are positive and negative implications of that proximity to the highway and the flows of through traffic that currently use it. The constraints of connection to the road, and the implications of introducing Transmission Gully must be subject to separate traffic planning analysis, and proximity to this roading infrastructure may or may not prove to be a restriction on possible intensification here.


• Pukerua Bay has a complex topography with areas of reasonably flat land interspersed with steeply sloping gullies, and steep hillsides with slopes in excess of 15° to the west.

• Draft Significant Natural Areas are identified in gullies and other areas of steeply sloping land. Exclusion of medium density residential development on those is unlikely to have little effect on residential yield, as it is unlikely they could be built on.


• The noise corridor related to SH1 passes directly through the centre of Pukerua Bay. This might be mitigated by location-specific noise mitigation measures where needed. It is likely that the topography will shield some areas from road noise. In some instances however topography opens the land to road noise, and many of the western parts of the road corridor also have a south facing slope greater than 15°.

• The GNS 2014 Earthquake Fault Avoidance Zone passes diagonally through Pukerua Bay, to the north-west of the SH1 corridor. The development implications of this are addressed by others.


2.6 Character Assessment of likely effects on character informed by building footprint and 3D views.

Increased site coverage from 35% to 45% will be the major factor in character change, and the character-related effects of intensification with greater site coverage and increased building height from 8m (or two storeys) to 11 metres (or three storeys) will include:

• Significantly increased paving required to serve vehicles access to and parking on site.

• Assuming site coverage is to the maximum, should all buildings be built to the proposed 3 storeys (rather than the currently permitted 2 storeys) then the consequent additional requirement for on-site car parking and vehicle manoeuvring can be expected to further increase the demand for on-site parking and vehicle manoeuvring.

• Loss of existing vegetation and trees due to the combined effects of greater site coverage and increased paving requirements and significant reduction in potential to plant trees due to the above.

• An additional effect of this is the quality of outlook from dwellings, both into their own land which will become increasingly dominated by buildings and across boundaries, and the reduction in substantial planting such as trees that provide excellent visual privacy between dwellings.

• Increased shading on sites below when three storey development is constructed on a south-facing area, and also but to a lesser extent when the taller new development is located at high level on steep east and west facing areas.

• In some areas characterised by predominantly one-storey dwellings, a building scale juxtaposition across boundaries.

Apart from in any areas of comprehensive redevelopment, character change will be incremental and will occur over a large period of time. It is unlikely that it will be complete, and there will be parts of areas and individual lots such as those with difficult topography and less propitious sun and outlook that are less suitable for intensification and where intensification does not occur at all.

It will be important to consider the quality of development as a concentration of poor quality, low amenity housing will compromise the quality of its immediate setting and can also undermine the quality and perceived character of the wider neighbourhood.

2.7 Slope and Shading Effects Any south facing slope of 15° or more is not suitable for medium density residential development. For the purpose of this assessment, a south facing slope is defined as facing between south east and south-west, which encompasses a 90° arc. Our previous investigation found that “recession planes (3.0m + 45°) are ineffective in addressing midwinter sun at noon on south facing slopes with a


gradient exceeding 15° and with development higher than 8m/two storeys to the north.” These south-facing slopes create a condition where medium density development should be excluded. There will be other slopes oriented slightly north of SW and SE that are also problematic, and in this case shading and sunlight in MDR development should be addressed by design controls. A steep north facing slope will provide excellent solar access, and in the context of a north-facing coastline also excellent views, so potentially offers very high residential amenity. While there may be development costs associated with utilising steep north facing sites, that might be up to the developer to balance with the higher amenity, and consequently higher value return that might be expected.

2.8 Confirming final zone boundaries

There are two types of approach to any special characteristics within each zone such as ‘Significant Natural Areas’ and ‘Earthquake Fault Avoidance Zones’. This might be by recommending zone boundaries to exclude such areas or setting broader and more general boundaries within which special overlays apply which might consequently trigger special controls in those overlay areas. An urban design and planning analysis, this report avoids making recommendations on the significance of those special areas and the optimal way to manage them, and therefore recommends broad and more general boundaries. This is with the expectation that specialist inputs from others will either adjust the recommended boundaries or place overlays within identified zones.


3 Methodology

3.1 Process

The following steps have been followed: 1. Areas reviewed are those identified by the Porirua City Growth Strategy,

being ‘Compact Regeneration’ and ‘Compact around Public Transport’

2. Review entire data set. PNCC Overlay Mapping in digital form. Extracts from this are included in section 4 of this report. This PCC mapping identifies the areas that are within identified distances from various destinations, services and/or infrastructure.

3. Focus on primary social and access infrastructure that is typically accessed on a daily basis, being:

a. Draft Local Commercial Zone b. Recreation, Playground and Sports fields 400m

Those drawn are Council owned fields. The fields associated with schools are additional.

c. Public Transport. d. Schools

and on factors which might preclude development being: e. South-facing aspect and slope greater than 15°

Proximity to secondary destinations and infrastructure is valuable however these are not the determining factor in recommending where medium density residential would be appropriate. Such destinations include:

f. Medical Centres 400m g. Shared Pathways (Off-road cycling) 1000m h. Libraries, Marae and Community Halls 400m i. Swimming Pools 400m

Considering distance from facilities: In principle, a greater walking distance from home may acceptable if the time spent at the destination warrants that. While short walking distances are always most convenient, therefore a walk of 1000-12000m to the train to commute to work for the day will be acceptable. Conversely facilities that might warrant only a 15-30 minute visit (such as a local playground) need to be conveniently close if they are to be used such as a

4. Overlay of additional information to assist interpretation, and processing

of slope gradient and orientation data mapping.

5. Overlay mapping to identify the areas which are not well-served by these facilities and which include relatively large areas or concentrations of land with a south facing aspect and slope greater than 15° Additional information such as locations of playgrounds, schools and local centres (and identification of the latter two) has been added

6. Verification of recommendations against full data set (as in section 4)


7. Character effects assessment Review existing building footprints and 3D building form for each area, and review previous character report.

8. Map recommendations and record rationale.

9. Verification with field study and confirmation of recommendations in consultation with Council officers follows this report.

3.2 List of Data Analysis Drawings

The following drawings have been prepared for each of the four identified areas: 1. Potential Areas for Rezoning 2. Recommended Area for Rezoning (This shows the recommended area

only laid over the ‘potential areas for rezoning’ drawing and a second drawing showing only the recommended area for rezoning.)

3. Draft Local Commercial Zone – 800m 4. Recreation, Playground and Sports Fields – 400m 5. Public Transport 6. Schools

4 Mapping Dataset

The following have been extracted as ready reference to individual layers of information which are included in the Porirua City Council interactive digital database for this project. Interpretation relative to each drawing is included. Extracts from this dataset have been used for the graphic analysis described in the Data Analysis Drawings, and have also been used to inform the findings and recommendations of this report. List of drawings:

• Potential Growth Areas

• Public Transport

• Schools

• Medical Centres 400m

• Recreation, Playgrounds and Sports Fields 400m

• Shared Pathways (Off-road cycling) 1000m

• Libraries, Marae and Community Halls 400m

• Swimming Pools 400m

• City Centre and Local Commercial Zones 800m

• Draft Local Commercial and Mixed Use Zones

• Draft Significant Natural Areas

• Noise Corridors and Flood Hazard

• Earthquakes and Tsunami

• Slope greater than 15 degrees

• Slope aspect


Potential Growth Areas

The Porirua City Council Growth Strategy identifies the following areas as being potentially suitable for growth: Growth Strategy – Compact around public transport

• Pukerua Bay and the City Centre eastward and encompassing part of Porirua East

Growth Strategy – Compact Regeneration

• Titahi Bay, Kenepuru and the eastern part of Porirua East, Cannons Creek and Waitangirua.

These boundary lines shown here in purple are included for ease of reference on all drawings that follow.


Public Transport

‘Train station 1000m’ is shown in red. (A further PCC dataset shows ‘Train Station 800-1200m’.) ‘High frequency bus stop 400-500m’ is shown in amber.

Interpretation

• Appropriate access to good public transport is a primary consideration in determining areas that are suitable for residential intensification.

• The mapping demonstrates existing high frequency bus routes and stops. Where significant intensification is planned it is assumed that additional routes and new, relocated or additional bus stops might be added.


Schools

‘Schools 400m’ is shown in light blue ‘Schools 1000m’ is shown in dark blue

Interpretation

• Appropriate access to schools is a further primary consideration in determining areas that are suitable for residential intensification.

• While a 400m walking distance provides excellent access, given that students spend the entire day at school, the 1000m distance is used as being most relevant to determining if access is sufficient. In addition it is unlikely that primary schools would be provided, as a rule at not more than 800m centres.

• This mapping shows that virtually all of the proposed growth areas have good access to schools.


Medical Centres 400m

Interpretation

• Medical centres, while a valuable asset in any neighbourhood, are not a determining factor for intensification as they are not necessarily facilities that people must access on a daily basis. Furthermore, new such facilities can be built in areas of comprehensive redevelopment and intensification.


Recreation, Playgrounds and Sports Fields 400m

‘Playgrounds and Sports Field 400m’ is shown in green. ‘Recreation (Sports, Playground, Kickabout) 400m is shown in pink and also underlies all of the ‘Playground and Sports Field’ areas identified in green.

Interpretation

• Where comprehensive renewal or intensification is proposed, recreational facilities including kickabout areas, playgrounds and sports facilities (other than sports fields) might be readily integrated. That is, some of these facilities can readily be integrated into a site development plan, so their absence does not become a determining factor for the presence or otherwise of intensification

• If that is the case, the subdivision and structure planning controls must ensure that adequate provision is made.


Shared Pathways (Off-road cycling) 1000m

Interpretation

• Existing shared pathways for off-road cycling is not a determining factor as roads can be modified to provide these facilities.

• These should be required in design controls, particularly in areas that may be comprehensively redeveloped.


Libraries, Marae and Community Halls 400m

Libraries are located in Pukerua Bay, Titahi Bay, the City Centre, Cannons Creek and Whitby. Marae and are Takapuwhahia (off Titahi Bay Road), Waiatangarua, and Horouta (on Whitford Brown Avenue) and north of Plimmerton on Hongoeka Bay Road. Community halls are at Porirua East, Mana and Plimmerton. These facilities are all described in yellow.

Interpretation

• These community facilities are not a determining factor for intensification as they are not necessarily facilities that people must access on a daily basis. Furthermore, new such facilities can be built in areas of comprehensive redevelopment and intensification.


Swimming Pool 400m

Proximity to a public swimming pool is shown in yellow

Interpretation

• These community facilities are not a determining factor for intensification as they are not necessarily facilities that most people will access on a daily basis.

• Some areas, such as Titahi Bay, Mana and Plimmerton have access to the beqch which also provide for swimming.


City Centre and Local Commercial Zones 800m

The Draft City Centre Zone is identified with solid blocks, and both City Centre Zone 800m and Draft Local Commercial Zone 800m are identified with lilac The overlap of the former on the latter shows as a more intense shading.

Interpretation

• The centre of most of the areas being consdered for intensification are within 800 metres of a Draft Local Commecial Zone, hwoever many pereipheral areas are not well-served.


Draft Local Commercial and Mixed Use Zones

Draft Local Commercial Zones are identified in purple Draft Mixed Use Zones are identified in magenta


Draft Significant Natural Areas


Noise Corridors and Flood Hazard

Noise corridors are the orange band Flood Hazard – Stream Corridors are shown in blue Flood Hazard – Overland Flow lines are shown in gold


Earthquake and Tsunami

Grey bands are the Earthquake Fault Avoidance Zone (GNS 2014) Orange and red represent different categories of tsunami risk (Tsunami Porirua DRAFT 100 year)

Interpretation

• The implications of siesmic and tsunami risk for intensification will be determined by others.
