COMMENT

On a tight leash

Municipalities face severe delivery challenges. Are we responding appropriately?

The recent spate of municipal protests is a concern to all. There are (again) calls to fire people who are not performing.

In this case, it is perceived to be the councillors. But, as we’ve come to realise, it is not as simple as that. Well-known commentator Steven Friedman is of the opinion that, as long as municipalities are viewed as implementing agents for national plans, we are going to face similar problems. The democratic ideal is that councillors, as representatives of their constituents, choose priorities for a municipality but, according to Friedman, they are expected to do this within the ambit of national policies and programmes that actually limit local government’s choices.

Co-operative governance often results in blurred responsibilities and, at local government level, it has often neutered the democratic process. Councillors are supposed to be the voices of their voters but they often become mere implementing agents and assistants to national government instead.

The abolition of Regional Services Council levies has been a big blow to the metros. The replacement grant has not maintained the growth trajectory of this revenue flow and municipalities are now forced to jump through hoops to satisfy national government objectives to access grants. A case in point is the Neighbourhood Development Partnership Grant, which is administered by the National Treasury. This grant makes about R3,4-billion available to municipalities over the next three years.

All is well but Treasury is keeping tight control over this money.

Should it be the national government department that makes decisions on how to assist “municipalities with technical assistance to develop appropriate project proposals for property development in townships and new residential areas”? Surely this should actually be administered by either Provincial and Local Government or perhaps even Land Affairs?

It is understandable that national government wants to help solve the problems at local level but maybe it is going the wrong way about this. It is time to treat municipalities differently.

And it is time to treat different municipalities differently.

Development ad hoc
Port Louis, capital of the island state Mauritius, faces similar problems to other developing cities. A visit by Urban Green File revealed that a few of the city’s developments are on a fairly ad hoc basis – without a coherent plan to address the city’s major issues. Turn to page 16 for an in-depth look at urban development in this fascinating coastal city.

BOOK REVIEW
Who pays for your holidays?

The impact of tourism has become a headache for local authorities and residents the world over.

With 2010 on its way and the recent buzz about global warming, the impact of tourism is a topical issue. The Final Call by Leo Hickman – a 386-page book “in search of the true cost of our holidays” – addresses this topic. Hickman, a newspaper columnist writing for The Guardian in the UK, has already written several books about ethical consumerism. For his latest, he travelled to a wide range of popular tourist destinations to investigate the largest service industry in the world. He visits the Spanish coastline (nicknamed ‘Costa del Golf’) where in 2005 alone 130 golf-course developments were under way within the Valencia and Murcia regions. He also visits a skiing centre in Dubai where 6 000 t of snow is kept frozen. But, although making snow in the desert sounds ludicrous, Hickman discovers the same in the snowy Alps where, to please visitors, water is pumped from reservoirs, frozen and sprayed onto the slopes to create even more snow. Hickman also investigates ‘sex tourism’ in Thailand, partying in Ibiza and package holidays on the Mexican peninsula, among others. It is an easy book to read as it is actually a pleasant mix of travel writing and informed comment. In addition to addressing the environmental impact of tourism, such as ‘green washing’ in the ecotourism industry and a very informative chapter on the real costs of ‘cheap’ airfares, Hickman also interviews local politicians, urban managers and business people to understand social and economic impacts. Of course, tourism has broader economic and social implications, and issues that can only be addressed at national policy level but, in our professional capacity as urban and environmental practitioners, it is essential to consider valuable lessons to be learned worldwide.

Hickman concludes with some proposals for local authorities, such as the possibility of capping the number of tourists allowed to visit sensitive areas; the importance of very strict development plans; and clustering tourism with other economic activities.

Published by Random House and retailing at R208, The Final Call is certainly interesting although some of the solutions seem a bit ‘pie-in-the-sky’. Perhaps the same criticism was levelled at anti-smoking lobbyists just decades ago.

UPFRONT

River mall
Construction of the much-publicised, R400-million Mooi River Mall in Potchefstroom, North West Province, is well under way. The Mooi River meanders through this 14 ha site.

Ray Shaw, the architect with Stauch Vorster responsible for the project, tells Urban Green File that the main challenge facing the developers and the architects is the river itself. “Environmental issues required that the final development and the construction phase had a minimal impact on the state of the river.”

Environmental impact studies have been conducted and an environmental officer is stationed permanently on site. No work is allowed to proceed until methods and schedules have been, approved by the environmental officer. Each job is approved separately to ensure control on a continuous basis, and all contractors and sub-contractors have to comply with stipulated standards.

The area around the Mooi River in Potchefstroom has been kept in a clean state despite building activities on both sides.

Coastal development
The Blythedale Coastal Resort is being established about 45 minutes north of Durban on the northern boundary of Umhlanga. Comprising forest, ocean and golf estates, the greater ‘coastal resort’ will house around 4 400 units – some sectional title and others freehold ownership. Fringe developments include an equestrian estate, a retirement lifestyle village, a hotel and water theme park, social housing and beach nodes.

Land used for timber and sugar-cane farming, purchased by the eLan property group, will be rehabilitated to standards prescribed by the environmental impact assessment. More than 50% of the land – largely indigenous forest – will remain undeveloped. Protection of the environment is important to the developer.

Shayne Isbister of eLan says “every measure has been taken to contain the impacts associated with development in this delicate ecosystem”.

The 1 100 ha patch of land to be developed between the N2 highway and the seashore in northern KwaZulu-Natal is flanked by the villages of Blythedale and Prince’s Grant.

New CID
The Cape Town City Council has approved the formation of a 15th City Improvement District (CID) within the city. The Athlone CID will include the area bounded by Jan Smuts Drive, Aden Lane, Birdwood Street and Klipfontein Drive.

Collectively, the 15 CIDs in Cape Town have an annual budget of more than R50-million, which is collected by the city and paid to the respective CID management boards. This funds their activities in accordance with their business plans.

Into Africa
After four years, the planning of the Lagoa Azul resort on the island of São Tomé, off the west coast of Africa, has been completed.

Lagoa Azul (Portuguese for ‘blue lagoon’) is a 310 ha residential, golf and leisure estate. According to Jan Greyling of the Falcon Group (developer of the resort), the resort plans to serve a large expat community working for oil companies and the like in the region.

Construction will be a major logistical challenge as it is estimated that about 750 000 t of equipment and material will have to be transported to the site. Southern Mapping Company has been appointed to conduct lidar aerial surveys. These surveys are not restricted by the dense jungle-like vegetation on the island and the design team could make an exact estimate of the ground conditions.

A number of South African consultants were involved with the planning and design. Located on a pristine, unspoilt Greenfield site, Lagoa Azul has a 4 km beachfront.

Plant closure
The loss-making Radnor compost plant in Parow Industria, Cape Town, has been closed to free up council resources for better service delivery.

The Radnor plant and a similar facility in Bellville South were assessed in terms of the city’s core functions.

According to Clive Justus, utilities portfolio chairman for the City of Cape Town, both sites are older than 30 and have outlived their original function.

“They need extensive repairs and replacements to enable them to deliver a quality product.” The last costing exercise indicated that it would cost R482 to produce 1 t of compost at the Radnor plant and the private-sector selling price ranges from R150/t to R200/t”.

The City of Cape Town acknowledges that composting plays an important role in reducing waste but the Radnor plant is not cost-effective as it is too old and in a state of disrepair.

Outstanding reports
A group of environmental NGOs, including the Endangered Wildlife Trust, BirdLife South Africa and the Botanical Society of South Africa, has called on government to release certain strategic national planning reports. In 2004 and 2005, the Department of Environmental Affairs & Tourism (DEAT) began compiling the National Environmental Outlook (formerly the State of Environment Report) and the National Framework for Sustainable Development (formerly National Strategy for Sustainable Development). Nearly three years down the line, the National Environmental

Outlook has been released but the other report is not yet out. Lack of access to this information is often a stumbling block for NGOs and, indeed DEAT officials, attempting to achieve reasonable goals.

ENVIRONMENTAL PLANNING AND DESIGN

A lake for living

Careful environmental design and management have turned the area around an old saline lake into a place for quality living.

Located in the Noordhoek Valley of the Western Cape, contiguous to the Table Mountain National Park, Lake Michelle is a 30 ha saline lake. Previously a sand mine, the idea of a waterside development took root about 20 years ago.

Development rights have been obtained and the eastern banks of the lake, covering about 30 ha, have been developed over the past two decades.

About four years ago, developers Plan Trust Development went into joint venture with the owner of the site to develop the remaining 30 ha of the residential estate. A professional team was appointed, including CNdV Africa as landscape architect, planner and urban designer. According to Tanya de Villiers of CNdV, the developer ‘inherited’ a previously-approved subdivision. It was recognized that a one-of-a-kind, environmentally-sensitive scheme could be achieved by reducing the density and increasing the proportion of open space together with larger erven, particularly along the national park boundary. The adapted layout provided for about 7 ha of reed beds and artificial ponds, cleaning the lake water while offering more waterside properties alongside the new wetlands.

One of the positive aspects of the project was that it was entirely a team effort.

“Architects, landscape architects, engineers – we were all involved in the layout.

Especially for a landscape architect, this is great, because, usually by the time that we get involved, most of the other work has been done and you have to work with what you get. But, in this case, everything was discussed by everybody,” De Villiers says. The experienced multi-disciplinary team included, among others, botanists, aquatic specialists, geo-hydrologists, engineers, surveyors and landscape architects.

The design team was sent to Florida in the United States as the development of ‘inland marina’-type developments is very popular there. According to Colin Bird of Plan Trust Development, a total of 224 plots were eventually developed. Architectural guidelines were drafted but, as part of a conscious decision, these did not reflect a specific identifiable style.

The final development will not only be guided by architectural guidelines but very specific planning guidelines on entrances, building lines, garages, jetties and the like. As De Villiers puts it, it is almost pre-designed at that level.

Detail design
Ecological links
An important part of the design was to maintain ecological links with the adjacent national park and nearby wetlands. Palisade fences had to be permeable to allow movement of, among others, small animals.

Traffic calming
Roads are designed with traffic-calming measures in place to maintain tranquillity in the pedestrian-focused residential estate.

Pedestrian focus
Principles of ‘new urbanism’ were embraced and the design supports community interaction through various aspects, such as pedestrian paths. CNdV was lauded for the design of the wooden walkways with an award.

Quality principles
Finishes throughout, from the entrance buildings, roads, decks and paving to the multi-functional boat house, were chosen specifically for aesthetic quality and to create a tranquil and safe living environment.

Illuminated signage
Signage was carefully designed to ensure not only legibility but also aesthetic quality. Lighting used to illuminate signage by night had to fit in with the overall approach of restricted down lighting.

Bridge detail
The little bridges that cross the various canals were designed in detail with the cladding fitting perfectly into the culverts.

Semi-permeable walkways
Units are clustered to maximise the green spaces. In order to minimise hard surfacing, the numerous walkways have been constructed using semi-permeable materials.

Boat house
Besides numerous jetties and decks provided, a communal multi-functional boat house ensures that the lake can be used for non-motorised boating and canoeing.

Environmental management

From an environmental perspective, this part of the Western Cape is very harsh – issues such as water quality, alien vegetation and conservation of existing animal life posed significant challenges to the design team. Nevertheless Lake Michelle was selected as the country’s top estate in the annual awards for excellence in property development by the South African Property Owners Association. As part of the overall environmental plan, the developer has taken out an insurance policy and established a fund to cover unforeseen environmental costs, as well as the maintenance of the water quality of the lake.

1 ‘Search and rescue’ – saving indigenous vegetation

The site had to be cleared of very dense alien vegetation but some of the lake edges and moist areas contained plants that were identified for rescue prior to earthmoving. The plants were removed from the site and taken to a local nursery where additional numbers were propagated to use on site. The species list included Juncus sp, Chondropetalum sp, Bulboschoenus maritimus, Schoenoplectus scirpoides, Carex clavata and Scirpusnodosus.

Islands in the lake were also cleared of aliens, leaving only a few dead trees for birds to nest, and were then re-vegetated with endemic species. Through the ‘search-and-rescue’ exercise, about 50 000 indigenous plants were rescued, according to De Villiers. In total, 300 000 plants were specifically propagated for the project.

The site has an exposed coastal climate with high winds in summer and winter. In addition, the salt content of the coastal sands meant that portions of the site had elevated sodium contents, placing significant restrictions on the choice of plant material. The use of local indigenous plants was seen as a way to ensure sustainability of the landscape, reduce the environmental impact of the development and link it with surrounding natural areas.

De Villiers believes it is not really a site for trees so the team had to experiment a bit to find the most salt-tolerant and hardy plants.

Also water consumption of the alien vegetation replaced as a result of the development probably exceeds the projected consumption of the entire development upon completion.

2 Careful monitoring – water-quality improvement
Environmental requirements demanded that water quality of the existing lake should be improved during stagnant periods. The water is very high in nitrates.

As mentioned, the new layout provided for about 7 ha of reed beds and artificial ponds that serve to circulate and aerate the lake water. The improved bio-diversity wetland habitat had the valuable effect of helping to reverse deteriorating water quality in the existing water body.

An ongoing water management plan has been drafted. Estate manager Joe Daniel tells Urban Green File that water is monitored continuously and there must be no overflow into nearby wetlands.

All stormwater run-off is led through reed beds before entering the ponds.

The design implied that there was no need for a piped stormwater system.

The development potentially contributes to the improvement of stormwater quality in the entire Noordhoek Valley as stormwater from all of the surrounding areas flows into the lake before going on to the national park.

Although it has improved, the salt content of the water is too high to use for irrigation. “We had plans to get treated effluent from the nearby municipal sewer works but, although the municipality was keen, they are still at least two years away from making it available,” Bird says. “We also looked at desalination as an option but it is quite expensive so we installed two blending plants where we mix the salty water from the lake with municipal potable water to use for irrigation. At the moment it is done at a ratio of about 50:50. Eventually this will go down as the water quality of the lake improves.”

However only small areas of grass were allowed as the development team did not want to use too much water for irrigation purposes.

3 Promoting diversity – urban-wildlife preservation
To enhance residents’ lifestyles and in line with the sound environmental principles followed in the Lake Michelle development, the development team also had a look at the existing ‘wildlife’ in the area in order to find ways to protect it and to promote its diversity. The Cape Bird Society has already had two visits to the site. In addition to the wading birds attracted to the lake, there is a surprising variety of birdlife around the estate. A large number of Egyptian geese reside there and some kingfishers have been spotted too. The plan is for the Cape Bird Society to conduct an annual bird count in the area. Another interesting aspect of the development is the fish population in the saline lake. The predominant species of fish in Lake Michelle is the non-indigenous carp, which is a bottom-feeder and, by habit, increases the turbidity of the water.

The result of this behaviour is that the sun cannot penetrate so natural reeds are unable to grow. The development team plans to cull the alien carp and to replace it with indigenous species of fish. Colin Bird of Plan Trust Development says: “It is, however, not so easy to get rid of them. We had experts in to do a fish census and they found that we actually have a large population of indigenous fish. We had been experimenting with nets to catch the carp but that was not very successful.

So we launched, as part of our public relations, a fishing competition for the local schools. We tagged three fish and the local children were allowed to come in and fish here in the afternoons. One of the tagged fish has been caught and there is growing interest within the community to continuously work towards reducing the carp in this way”.

CITY VISIT

A city is not an island
Port Louis, capital city of Mauritius, is at the heart of the island and its development cannot be approached in isolation.

Port Louis is eccentrically located in the Indian Ocean on the island’s north-west coastline of Mauritius and nestles in an amphitheatre of mountains.

Today it is faced with challenges common to many other city centres the world over, including expansion, traffic congestion, changing land use and the loss of its local identity.

Port Louis was established in 1735 by the French as a halt for their ships traveling around the Cape of Good Hope.

A feeling of uniqueness emanates from the co-existence of traditional Mauritian timber structures alongside more modern concrete and glass edifices. Upon arrival, a visitor’s first impression is the tropical quality of the city’s light and colours, the hustle and bustle of busy vendors, and the serious congestion. This is epitomised by the motorway, which effectively dissects the CBD from the port in a north-south direction.

The city is easily legible – the CBD articulated by gleaming high rises, surrounded by smaller-scale, mixed-use commercial, retail and residential areas, and the pavements jam-packed with informal stalls. The large, predominantly residential, area to the north is separated from the CBD by La Citadelle, a fortification built by the British in 1835.

“Port Louis is the main and only port of the country with the whole area around the sea devoted to port-related activities,” says Pang Kin Lan, the city’s head planner.

The most popular mode of transport is by bus. At one point, a rapid rail transport system was being considered but this is still in the pipeline. Many people also opt for motorcycles – they are better for coping with congestion and can move about more easily. The waterfront was done in phases about a decade ago to embellish the part of city that mainly comprised warehouses at the time – to become more tourist-oriented, Ramooguv Yongvaj, the city’s engineering assistant, points out. “Another project at the waterfront is now in its second phase – mainly commercial and retail activities. We also have an underground parking garage for 400 cars in the pipeline and a hawkers’ trading facility under construction.” These comments on the status of the city’s planning and development begin to hint at three main challenges: traffic congestion, residential decentralisation of the inner city and the ad hoc nature of projects.

These, in conjunction, are eroding the valuable environmental and historic fabric of the old town – the very things that tourists find most attractive.

An opportunity lost?
In 2004, the Union Internationale Architectes (UIA), in conjunction with the Municipality of Port Louis, launched an international ideas competition, approved by UNESCO, for the design of a master plan “to obtain a coherent and harmonious urban development plan” for the city. The first prize was ultimately awarded to ALD Associates, formed by Jean-Francois Adam (Mauritius), and Piet Louw and Dave Dewar (both from Cape Town in South Africa).

Unfortunately the project has not been implemented as national elections and a change in power took place shortly after the winning entry was announced.

In its proposal, ALD first identified some key qualities and attractions of Port Louis.

The proposal then went on to define two major challenges faced by the city:
*            The pressure from ever-increasing vehicular volumes.
*            The lack of respect for a number of potential heritage and natural assets.

Examination of these issues would seem to indicate that addressing the city in isolation is not an effective solution. A broader conceptual approach needs to be taken towards the planning and policies of the island as a whole to reduce development pressure on Port Louis, and to implement a set of guidelines for preserving and maintaining the cultural and environmental assets of the country.

“What applies to Port Louis also applies elsewhere,” notes Adam. “South of the city are the towns of Beau Bassin, Rose Hill and Curepipe. These each had their own public centre like beads on a string along the main road. With the recent economic boom, sprawl has increased, putting pressure on the town centres.

The individual boundaries are no longer there and they are losing their inherent qualities. The major issues are, firstly, the eccentric location of Port Louis and then its structure,” explains Louw. “It’s a through route and main transport route between the north and south of the island, and this route effectively becomes a barrier between the town and the sea because it is so intensely trafficked. So you have to look at the island in its totality to achieve a better balance. Secondly, the CBD has a very special character but there seems to be little awareness of the value of the townscape. So a lot of historical buildings are being demolished – small buildings with a very special Mauritian character that have withstood many cyclones.”

The proposal for the International Ideas Competition looks at addressing the transport knot and congestion in Port Louis at city, regional and island levels. Alternative inland transport routes have been proposed to relieve the burden of congestion on the city and to allow the CBD to connect back to the sea.

Trade port
The city of Port Louis opens out onto the sea in the form of a large port, which has defined the growth of the urban fabric.

Waterfront development
The waterfront was completed about a decade ago to embellish the part of the city that mainly comprised warehouses at the time and to create more tourist amenities.

Industrial area
The manufacturing district on the outskirts contributes to congestion on the routes through the city centre. The competition proposal recommends a decentralization of activities to help address this issue.

Traffic congestion
Many residents opt for motor cycles as they are better at coping with congestion and can move about easier than a car.

Untying the knot
The competition proposal states: “At the island scale, it is necessary to encourage steady, managed decentralization of economic activity in dynamic balance with new residential activity, and to commit to public transportation, taking the pressure off Port Louis.” 

On a larger scale, Adam says: “There is a movement towards the centre of the island, taking lessons from Port Louis, to create more of a balance on the island. I think it will be successful in the long term but decisions need to be taken in Port Louis to complement this move.”

Louw agrees. “At a city level, the balance between pedestrian and vehicular movement is getting increasingly distorted in favour of vehicles. Because of the domination of cars, you have increased specialisation of activities, with all the offices located in one place, and this causes further congestion. At the moment there’s a knot of transport and we believe that this knot can only be untied at the island scale”.

The proposal argues that untying the transport knot should happen through two conceptual switches: committing to prioritising pedestrians and conceiving road hierarchies as an integrated movement system rather than in a conventional sense.

Downgrading the existing section of freeway, which cuts between the CBD and the sea, to a landscaped boulevard would take the pressure off the northern part of town and allow for greater pedestrian permeability between the town and the waterfront.

A boulevard would also take into appropriate consideration the façades of buildings, pavements, landscaping, bicycles and dedicated public transport lanes.

“The last major development that happened in Port Louis was the waterfront,” adds Adam. “This has been a success because it is accessible to everyone and it could be further exploited.”

Place-making in Port Louis
1 Authentic race course

The Champ de Mars race course was inaugurated on June 25 1812. The Mauritius Turf Club is the oldest horseracing club in the southern hemisphere and is a popular destination.

2 Fine grain
The fine grain and scale of the existing historic grid is also being eroded as many streets become larger roads.

3Urban sprawl
While there is little major development in Port Louis, there is nevertheless a slow but steady sprawl outwards from existing residential areas. This will probably continue for as long as the geography allows.

4 Motorway
The existing motorway effectively dissects the CBD from the port. Proposals are in place to redirect traffic flow around the mountain.

5 High-rise skyline
The city’s skyline has completely changed in the past 15 years due to the construction of several high-rise buildings during construction booms in the past decade.

6 Waterfront initiative
The last major development that happened in Port Louis was the waterfront. The Caudan Waterfront revitalised a section of the city previously dedicated to warehouses as a commercial and retail complex for leisure and tourist activities.

7 Port influence
The old city opens out onto the sea in the form of a large port, which has defined the growth of the urban fabric.

An integrated approach
It is apparent that the few developments happening in the city are on a fairly ad hoc basis without a coherent plan in place to address the city’s major issues.

According to Yongvaj, the services and infrastructure are also just being maintained and any large new projects would have to happen with the backing of the Mauritian government.

“The public sector has the administrative power while the private sector owns most of the land,” says Adam. “There is a clear line between these two with very little interaction and exchange of ideas. At the same time it is difficult for a poor country like Mauritius to take courageous decisions.”

Port Louis is such an important issue, believes Adam. “It is the real heart of the island and it can’t only be the responsibility of a municipality – it’s a national issue.”

To implement a project like the competition proposal, according to Adam, it must be structured properly with coordination between the various parties involved. “For this to happen it would need a main partner, a champion, to take the difficult political decisions that are necessary,” he says.

Louw agrees. “To succeed, a project like this needs an integrated, interdisciplinary approach where there’s a common vision and everyone works in line with that vision.”

To retain the distinct character and assets that attract so many tourists every year, and to avoid falling into the trap of becoming just another commercial capital city, a holistic, decisive approach is required for the future development of Port Louis – to conserve the past and carefully structure the way forward.

Structural clarity
Geographically, Port Louis is reminiscent of Cape Town but on a smaller scale and with a much more European colonial flavour.

Narrow roads and lanes laid out on an orthogonal grid define an urban fabric of diverse building languages interspersed with pockets of greenery.

Louw says: “There is a wonderful structural clarity to the old town, which anchors the urban layout and provides a hierarchy of systems that act as a backbone for the city layout.” This structure centres on a major north-south axis and an east-west axis connecting the Champs de Mars race course with the harbour, integrating the major public buildings, and it includes a number of public spaces with distinctive planting.

Growth management
According to Lan, agricultural areas on the outskirts are being converted for residential use and now fall under the jurisdiction of the city. This will probably continue for as long as the geography allows.

“The indigenous flora and fauna around the city is suffering,” explains Adam. “Mauritius’s real attraction lies with its natural amenities,” adds Louw. “All four coastlines differ in nature and character, and the first action should be to establish which areas must be conserved and remain undeveloped.

I believe that the authorities need to be firmer to protect these qualities and pass them on to future generations.”

Urban form
Increasing congestion and the emphasis on commercial activities in the CBD is causing an unfortunate erosion of Port Louis’s sense of place. This is happening on several levels, primarily the demolition of buildings of traditional and historical significance, and the reduction of pedestrian amenities.

The proposal also recommends a revised approach to informal trading. Hawkers and shops display their wares profusely along pavements. This tends to crowd pedestrian movement. New market buildings are recommended with associated open-air squares to allow for additional trading.

One such project, commissioned by the municipality, was completed in 2006 while another is under construction.

A cause for serious concern in Port Louis is the demolition of culturally- and historically-valuable buildings to make way for commercial developments. One of the extraordinary experiences as a visitor to the city is coming across traditional timber homes – hundreds of years old – that have miraculously withstood the devastating cyclones that frequently batter the island. These structures have a very special, awe-inspiring quality.

Cyclone season in Mauritius runs from December through to March and the storms have caused much destruction on the island over the years.

The result was a permanent shift in popular mindset towards concrete construction, which became the most logical, if somewhat costly, choice for most of the country’s inhabitants.

Concrete-framed structures predominate with cement-ash bricks used as infill. Unfortunately this has resulted in not only the loss of valuable historical buildings but also the loss of knowledge about traditional building methods.

Day-time use
“The centre is primarily commercial, accommodating local and multinational businesses, with an industrial component on the outskirts,” says Lan.

“At the moment, maybe because of the high cost of construction, there are just a few new developments.”

The resident population of Port Louis is located mostly on the outskirts of the city as an increasing number of residential buildings in the city center are being converted to offices.

“The inner city is not essentially residential so we have a population in the centre during the day that is almost double the population at night,” Lan points out.

WASTE AND POLLUTION MANAGEMENT  

How green is your landfill?
The Mariannhill landfill in the eThekwini metro has achieved conservancy status. Can this ‘green’ initiative be replicated elsewhere?

The Mariannhill landfill is most certainly the ‘greenest’ landfill site in South Africa. It opened 12 years ago, achieved conservancy status in 2003 and has gone on to be one of the most environment-friendly landfill sites in this country – if not the world. It is also the first landfill gas-to-electricity clean development mechanism (CDM) project in Africa. The innovative approach and management of the landfill was recognised by the Impumelelo Innovations Award Trust as an exceptional model of public service delivery in February 2007.

The Mariannhill Landfill Conservancy has a two-fold investment: it invests in environmental protection by adopting a ‘closed-loop’ concept to safeguard its biodiversity assets, and it manages landfill gas emissions as an asset; simultaneously reducing carbon emissions.

Can all these firsts for a landfill site – conservancy and CDM status, as well as awards for innovative management – be replicated on the 2 000 other landfill sites throughout South Africa?

A point of clarity: a conservancy is a community-based conservation initiative.

The managers and owners of the land can draw from a pool of resources to help manage land in a sustainable manner while maintaining ordinary land use.

The National Association of Conservancies of South Africa was established in 2003 and protects 750 conservancies.

Different aspects
Four main policies have been adopted to prevent environmental contamination and to restore and conserve the spoiled environment at the Mariannhill landfill.

A barrier system, not necessarily new to landfills, prevents landfill liquid waste, leachate and gases from escaping through the ground.

Leachate treatment at Mariannhill is innovative in that it is treated at 50 m³/day and aerated using natural processes so that water can be released into the environment.

Leachate is ordinarily fed into sewage water where its high nitrogen content may be corrosive and dangerous.

Methane gas is also being tapped. Instead of letting it flow into the atmosphere where it could continue to contribute to the greenhouse effect, gas is transformed into electricity through carbon finance.

Indigenous plants and topsoil that have been rescued and then stored in a plant recovery unit (PRUNIT) are introduced back to completed areas of the landfill and its borders.

4 interventions
1 Environmental protection
– barrier system
Natural biodegradation processes within waste bodies give rise to landfill leachate – produced as a result of rainfall passing through the waste body – and landfill gas.

The protection of the receiving environment from these potentially-harmful landfill emissions is addressed in the form of a barrier system (incorporating a number of engineered layers). According to Lindsay Strachan of eThekwini’s solid waste department, two types of barrier systems have been adopted at the Mariannhill landfill site, depending on the grade of the natural ground. On valley slopes, the barrier system consists of a stabilised sand layer with a geomembrane (of flexible polypropylene) liner and geogrid on it. A stabilised sand protection layer is then constructed on the liner/geogrid. Crushed dump rock aggregate is then placed on this protection layer to facilitate the collection as well as the removal of leachate.

In the valley basal areas, an additional component is added to the barrier system.

As the inflow of leachate into the strata below the landfill is critical in the valley base, two low-permeability clay layers, with a layer of 19 mm stone between each layer, are constructed below the system. The ‘sandwiched’ stone layer serves as a leachate leakage detection system and provides further environmental protection.

2 Irrigation use leachate treatment
The leachate was sent to the municipal sewer system prior to the construction of the treatment plant – an approximate distance of 1 km away.

According to John Parkin, manager of Durban Solid Waste (DSW), the disposal of leachate to sewer is not a treatment method but rather one of dilution.

Raw (untreated) leachate does pose a risk of corrosion and elevated methane gas levels to the municipal sewer systems.

DSW, in collaboration with Enviros UK (previously Enviros Aspinwall), began leachate treatability trials in 1998, which enabled the design of a full-scale treatment plant.

The overall treatment philosophy of the treatment plant is the use of natural, lowcost and robust treatment processes, says Parkin. This plant, therefore, adopts biological primary treatment processes (aligned to the activated sludge process) and secondary polishing treatment by reed bed Parkin explains.

The treatment plant comprises one sequencing batch reactor (SBR) unit, constructed of reinforced-concrete 10 m in diameter and 6 m deep. This capacity enables the treatment of up to 50 m³ of leachate daily.

The plant also comprises a 280 m³, lined reed bed that provides ‘polishing treatment’ for the removal of residual BOD, COD and solids.

All treated effluent from the SBR is fed into a balance tank. The level of this tank is controlled to supply a portion of the effluent to a standpoint for the site water tanker (dust suppression) and a portion to the reed bed.

The effluent from the reed bed is used for irrigation of the vegetated areas within the conservancy area.

3 Liability turned asset – methane gas conversion
Mariannhill landfill site is exemplary for the utilisation of its assets – whether in the form of carbon emission reductions (CERs) or biodiversity. It is the first landfill gas-toelectricity CDM project in Africa. Some 450 t of municipal waste is transformed to generate 900 kWh of electricity every day and it is fed into the local grid. John Parkin explains that the landfill gas extraction scheme consists of six gas wells, linked to a 500 Nm³/h flare unit, which has been operational for about 31/2 years. ”The gas collection system for the flaring has proved to be an adequate starting place as a pre-injection treatment system for the engine generators. As is typical of several other projects worldwide, landfill gas is drawn from the wells through pipes by extraction equipment and fed to an electricity generation unit and any surplus gas is flared,” says Parkin. The eThekwini municipality’s CDM project, commissioned in December 2006, will help combat the serious issue of global warming and find a financially viable use for the amazing power potential of landfill gas.

The October 2006 edition of Urban Green File featured South African initiatives for gas-to-electricity generation on landfill sites.

4 True rehabilitation – vegetation recovery
The status of Mariannhill as a conservancy lies in a clear understanding of the true meaning of rehabilitation – a rescue operation in safeguarding natural assets rather than a mere front-entrance face lift.

According to Richard Winn, businesses erroneously ‘face lift’ as rehabilitation and miss the point by interpreting the ‘green’ part of business as garden maintenance.

“To date, this process has produced plants of value in excess of R2,5-million but, more importantly, they are plants that could not have been purchased anywhere else,” says Parkin.

The DSW has created a ‘holding nursery’ for indigenous plants and topsoil rescued from the landfill – to all effects, a plant rescue unit (PRUNIT). The nursery began as a ‘tag on’ but burgeoned so that it now supplies other landfill sites, explains Aiden Bowers, operations manager for DSW.

Landfill plants have to be hardened off to handle the entire cycle of rehabilitation. A mobile irrigation system is used but major investment in irrigation is actually unnecessary.

The difference in this nursery also lies in the way the plants are transplanted.

Rather than a plant per bag as in conventional nurseries, four to five species from ‘upper storey’ plants to shrub ground cover are propagated together – these are tough plants.

No ‘soft luxuries’, such as compost and fertiliser, but local top soils and feed account for the 95% success rate of the rescue operation.

The strength of this environmental investment is zero maintenance and zero waste – now that’s what municipal dreams are made of, believes Richard Winn. For him, the key lies in recycling assets in the area. Instead of closing a landfill through a single ‘monstrous’ tender, an ongoing ‘closed-loop’ concept has significant cost saving implications.

It is less expensive and easier to invest in an ecosystem-restoration project in the initial phases of a landfill – as in the case of the Mariannhill landfill site – than to come back years later with a scientist to write doctorates on the recuperation of a depleted environment or, even worse, to lose entire ecosystems.

Can this be replicated?
With more than 2 000 landfills across the country, Winn believes that there needs to be serious transformation in the monitoring and management of these sites, based on a clear knowledge of the natural assets to recycle in any given local area. Operators often have little cognisance of the biodiversity contained in a particular ecosystem – not only the flora but also the soil habitat, and animal life.

Gas-to-electricity potential
Methane gas is significantly more lethal than carbon dioxide. There are more than 2 000 landfill sites strewn across 250 municipalities emitting these lethal gases.

“For every day that goes by without trapping methane gas, money is escaping into the atmosphere,” despairs Busi Nxumalo, business and market analyst for the CEF. Municipalities are sitting on CER assets, letting carbon finance ‘rot’ in their backyards so to speak.

Where a lack of funding is the hurdle to landfill gas extraction, Nxumalo points out that municipalities can rely on the Central Energy Fund (CEF) for equity financing and technological expertise. During August 2007, it will launch its carbon trading business, making it the first South African institution to provide comprehensive assistance for renewable energy projects. With less than five years to go before the Kyoto protocol ‘expires’, time is of the essence.

As a Schedule 2 company, municipalities can transact with the CEF, a government agency getting its mandate from the Department of Minerals & Energy, and avoid lengthy tender processes, explains Manny Singh, a general manager for the CEF.

The Municipal Finance Management Act is a stumbling block in this process as it is not designed for commercial pursuit.

Although the CEF was mandated to help ‘skirt’ this problem, Singh and Nxumalo believe that the Act should be reviewed.

It is destructive in terms of the value-enhancing asset of CERs for municipalities, they say.

Local connections
Most definitely the diamond in the crown of the DSW, the Mariannhill site is certainly not just sitting pretty. DSW is replicating the Mariannhill closed-loop concept for the new Buffelsdraai landfill. This forms part of its new management strategy – no coincidence then that the monitoring committee and the conservancy committee are one and the same. DSW manages all its landfills similarly even though, according to Winn, older sites such as Bisasar are more difficult to rehabilitate – retrospective rehabilitation is inherently more complex. Created before legislation had been promulgated, Bisasar had no buffer zones. It now has a 4 ha buffer zone close to houses on Clare Road; rehabilitated with plants from PRUNIT. The 50 wells at Bisasar Road will collect methane gas for another 20 years after the site is closed in five years’ time.

Bisasar is becoming a transfer station to Buffelsdraai and carries a far larger tonnage per day than Mariannhill because of its central city position. A gas extraction system is also planned for the Buffelsdraai landfill. At La Mercy, a closed landfill, gas is still being extracted and a Phase 2 extraction system is planned to increase the electricity generated.

The future for KZN
According to Bowers, a strategic planning meeting will be held in December 2008 to discuss how all landfill sites in eThekwini can be run as environmental assets – where vegetation dominates the landfill so that biodiversity around the landfill is enhanced.

In the case of the Mariannhill landfill, the conservancy improved the biodiversity in the surrounding area, Bowers points out. At other landfills, true rehabilitation is possible because of low overhead costs. The sub-tropical heat endemic to the greater eThekwini area makes a gasto-electricity project more feasible as landfill gases are generated more quickly and thereby effect a quicker return on investment through the CDM process. However, even in regions with milder climates, landfill operators are investigating this little used resource.

Gauteng solutions
At the Chloorkop landfill in Gauteng, privately-run by Enviroserv, a gas-extraction system has been installed and the landfill site achieved CDM status in May 2007.

Gas is flared but feasibility studies include the financial viability of a gas-toelectricity project.

Frans Dekker of the City of Tshwane agrees with Winn that rehabilitation while a landfill is operational reduces overall and closing-down costs.

In Gauteng, leachate is less of a problem as the cover material on the landfill has a lower silica content and a higher soil content than eThekwini. This results in less water penetration but more run-off water to administer and this could augment erosion. This is cited as one of the reasons to rehabilitate as the landfill operations progress.

The release of landfill gas can be reduced by creating compost out of garden refuse, Dekker points out. Compost is already sold from some landfill sites in Gauteng. Surveys are being done in Tshwane to determine the feasibility of extracting gas based on the amount of gas emissions on sites.

Western Cape joins in
Saliem Haider, manager of the solid waste department for the City of Cape Town, explains that the city’s mayor, Helen Zille, has bought into the idea of creating a similar landfill site to Mariannhill.

A team from Cape Town visited the landfill and is putting systems in place to replicate certain aspects of the Mariannhill landfill approach to design.

The challenge
Although the Mariannhill Landfill Conservancy may not be a feasible model in all contexts, it has applied innovative and value-adding management. Its resources have been harnessed to fullest potential.

This case study could help South African landfill managers and municipalities stand up to the challenge of ending irreparable and unnecessary damage to the South African and global environment.

PLANNING PERSONALITY

Chris Mulder exudes infectious enthusiasm.
Leading by example
Chris Mulder is certainly an impressive personality. He exudes conviction and efficiency in his vision to help redefine development in South Africa.

Mulder’s brainchild, Chris Mulder Associates Inc (CMAI) is becoming well-known for its work that marries upmarket residential development with economically- and socially-sustainable initiatives and community upliftment. “22 years ago, we sat down and set some goals for CMAI,” says Mulder. “The most important of these goals was to become known for sensitive coastal development in South Africa.”

A collaborative approach
At the time Mulder said: “It is important for us as planners, designers, decisionmakers and developers to blend our creative, technical and management skills with a professional ethic that shapes a sustainable future for people and the environment:

I guess it all boils down to how societies can meet basic human needs and nurture economic growth without undermining the natural resource base and environmental integrity”. Today Mulder still believes in that ideal.

CMAI’s mission statement is commitment to the environmentally-sensitive development of land, property and natural resources, and the company’s aim is to optimise the commercial, socio-economic and environmental value of all projects through multi-agency co-ordination. This involves a holistic approach supported by the diverse skills of a multi-disciplinary team, the unique creative contribution of individuals, and rewarding personal relationships with clients.

“I believe that there is no one skill or profession that can be involved in a project,” Mulder explains. “All role players must be aware right from the start what is involved. I insist on full consultant meetings all the time on every project, including the specialist consultants. I believe in absolute interdisciplinary collaboration and, over a quarter of a century, we have developed a unique process in this area.

Our projects are large – up to 2 000 ha sometimes. The approval systems are complex, and the design, planning and architecture have to respond to the region.

Often the sites are in super-sensitive areas like Thesen Islands. It took us seven years to obtain the approvals and seven years to construct, sell and build the 605 residential units on this site. We built 11 km of canals, the entire infrastructure and 100 multi-million-rand houses a year in five consecutive years. In this time, we also completed Thesen Harbour Town: the project’s own commercial centre. During this time, the full consultant team attended biweekly meetings and everyone was constantly aware of one another’s problems and ready to respond proactively.”

New approaches
CMAI’s work is mostly based on the concepts of ‘new urbanism’ and ‘new ruralism’.

New urbanism advocates liveable neighbourhoods built to reduce dependency on cars, provide easy access to public and commercial amenities, increase community interactivity, increase cost-effectiveness of services, and provide a simplified but higher quality of life. New ruralism works to create bridges between sustainable agriculture and new urbanism.

“I know and acknowledge that there is continuous debate on this topic, as well as people who support it and others who totally disagree with it,” says Mulder. “But we believe it addresses most of the housing and living conditions we face in South Africa. We have demonstrated very successfully that it works – it sells; it creates jobs; it contributes greatly to the local GDP and economy; it is sustainable; and people living in these developments love the lifestyle.”

Mulder is of the opinion that urban edge policies are restrictive, relatively undefined and unimplemented. “We support the principle of densification within the urban areas and an urban edge. However, there is nothing that can stimulate rural development in South Africa. I believe we should identify farmland with high potential as well as potential to accommodate residential development in either a scenic area or a place with natural attributes. The agricultural land should be set aside for agriculture development and the rest of the area should be developed in an economically-viable way. ”If we do not create such a policy or a guideline, how will the people living in the rural areas ever become participants in the economic boom we are experiencing now?” Mulder questions. “The growth we see now is something we have never experienced before in our life times and the rural people are totally excluded.”

Sustainable rural planning
Instead of building a model golf course, Mulder proposes building a model farm with everything required to be an economic and successful enterprise. This involves incorporating enough housing units to discount the cost of developing the farm – as in a golf estate. The fully-operational farm is thus debt free. A well-educated and capable farm management team would be appointed to run the farm while the labour component on the farm, as well as the managing team and the home owners’ association, would be given a substantial equity ownership in the enterprise. In this way, rural areas could be optimised while equity ownership in farmland could be provided to previously-disadvantaged communities.

“We are busy with six of these large-scale projects and, while the authorities still battle to understand how to incorporate this concept in their policies, we simply cannot wait. I think my long-term vision is shaped by my concern for finding solutions to sustainable rural development, and finding a way to allow the poorer rural population a bite at the economic growth that the country is experiencing. We need to find a way to regenerate the agricultural potential of the land and support rural lifestyles. We need to define a rural edge – an edge that forms a buffer between the natural areas that should be protected, the semi-natural areas that can be developed very sensitively, and the agricultural land that should be preserved and developed economically for agricultural purposes.”

Integrating experience and work
Mulder’s story is an unusual one and it is evident that his early working life has strongly influenced his characteristic approach to planning.

He originally studied soil science (chemistry) and horticulture at the University of Pretoria and was awarded a BSc (agriculture) degree. After farming for 12 years, external influences obliged him to reconsider his direction entirely.

“When I started farming, I was a share cropper: a guy who had no land and worked someone else’s land for 25% of everything he produced. I bought my first farm three years later and then bought two subsequent undeveloped farms with huge potential in the following 10 years.

The planning of these farms, the soil types and the vegetation interested me and I developed them according to what the land indicated to me. Soon after that, the previous government expropriated two of my farms for incorporation into the then Leboakgomo homeland. I was left with the original farm and had to make a decision to either buy again or do something else. I decided to go back to university, and obtained a masters degree in landscape architecture.

During this time, I drove the 180 km from the remaining farm to Pretoria and back twice a week. At that time I was chairman of the South African Farmers’ Union and director of the local co-op.

My wife, Pat, and children stayed on at the farm with the farm manager and staff, and Pat managed the farm. I arranged with the professors teaching professional practice and ethics, and history of architecture, to tape certain lectures, hired a student to tape them for me, and bought two tape recorders: one for the student who taped the lectures and one I kept in my bakkie. I would then listen to the lectures in my bakkie driving back and forth from the farm – the same lecture twice a week – coming and going. After three years, I graduated and decided that, as I had made this career change, I might as well go full out. I applied to three universities in the United States and was admitted to all three. I decided to go to Texas A&M

University as it had one of the largest architecture schools in the US, as well as an urban design and land planning/environmental design programme. It was there that I obtained a PhD in urban design and land planning.”

At the same time, Pat Mulder began an interior design course. Together they spent three of the most rewarding years of their lives, studying and working to support their four children. During that time, Mulder also spent time at Harvard University – in the terrain analyses programme and the aerial photo interpretation technology programme.

“The money spent obtaining a degree in the US pales into insignificance if one thinks back to what it meant to us and the kids.”

In May 1980, both Mulders graduated – she summa cum laude and he cum laude.

In spite of some good job offers, they decided to come back to South Africa immediately and start their own firm, which they did in July 1980. Mulder & Mulder set up offices in Pretoria. Three years later, the name was changed to Chris Mulder Associates Inc or CMAI, and additional offices were opened in Durban, Cape Town and Mossel Bay.

Because of the nature of their work and fields of specialisation, the Mulders ‘imported’ 16 American graduates (architects, urban designers and landscape architects) to work for them for more than a decade. Three of Mulder’s professors at the Texas A&M University’s college of architecture – Don Austin and Michael Murphy and John Motloch – later became colleagues and also worked at CMAI on several occasions. “They introduced me to the profession, the challenges and the opportunities,” Mulder acknowledges.

Murphy and Motloch graduated with a PhD from the University of Pretoria’s school of architecture with Mulder as their external examiner. CMAI also sponsored several South African graduates reading for masters degrees at Texas A&M. “All of them completed their degrees there, returned to work at CMAI, and then started their own successful professional practises, contributing meaningfully to the industry and the country.”

A sustainable legacy
True to the goal of creating sustainable developments with liveable neighbourhoods,

CMAI is busy with a number of projects that incorporate and preserve sensitive ecological areas. These include a small marina and agricultural village and estate on the Gourits River Mouth that will hopefully include seawater aquaculture and game farming; a waterfront development on the West Coast, which will also introduce large-scale seawater aquaculture and livestock farming; a project in the Addo Elephant Park; and a very environmentally-challenging new residential and commercial development in Knysna, opposite Thesen Islands, called George Rex Place.

The latter is situated on a severely-impacted wetland where large amounts of sawdust have been dumped. The land has been left to invader species and suffered rampant stormwater problems for more than four decades. With correct planning, design and mitigation measures, Mulder hopes to make this land as successful as Thesen Islands, just smaller in scale, with higher densities and more affordable price ranges.

On the subject of success, Mulder has this to say: “I guess success, like beauty, is in the eye of the beholder. I would call success achieving pre-set goals over a period of time; completing projects as planned and leaving happy clients and users; having people living in your developments telling you they got more than they ever hoped for or expected to receive; seeing young professionals dumped into the deep end, mature and take on responsibilities; and building up a potent team, with low staff turnover, working sometimes under extreme pressure and rising to the occasion, time and again. To maintain success calls for people not to rest on their laurels and the awards they receive but to face up to the challenges and opportunities this country offers us, and find unique solutions, implementing them and evaluating how you could have done better. The challenge is to create even better places for people to live, to find practical solutions to our problems, and to demonstrate to the world how we resolve them. That is why we call CMAI ‘the original thought factory’.”

BATTLE OF THE ’BURBS

Capricorn Park in Cape Town v Wynberg in Johannesburg
Industrial ’burbs: the past and the future?
The clean and neat Capricorn Park in Cape Town is the direct opposite of busy and somewhat grimy Wynberg in Johannesburg but both cater for industrial development. What are the differences?

Without the intention to fulfil this purpose, industrial areas such as Wynberg in northern Johannesburg are really mixed-use developments.

Although these areas are zoned industrial with certain requirements and guidelines, it is pretty much ’anything goes’. Walking through Wynberg, you will see high densities, different setbacks from the street, all kinds of activities: big and small, formal and informal. The lasting impression is that there is not much control.

Another type of industrial development has grown in popularity in recent times.

The 68 ha business-cum-industrial Capricorn Park in the southern suburbs of Cape Town does not resemble the traditional hustle-and-bustle and dirty picture of industrial townships at all. Driving into Capricorn Park, one gets the impression of space, cleanliness and control.

Management style
Surprisingly, the one thing that these two suburbs have in common is an alternative management structure. Capricorn Park is managed by means of a constituted property owners’ association. Speaking to Wendy Hartshorne, the development manager on site, one is impressed with the research that has gone into the development as well as the control that the association and its management seems to have over the activities of the park’s occupants. But, according to Hartshorne, this is the commitment promised to investors and occupants, and incorporated in the township’s conditions of establishment.

Increasingly, consumers require manufacturers to be environmentally-responsible and to ensure the highest quality in their manufacturing practices. At least one of the companies invested in Capricorn Park is exporting to the notoriously fickle food industry of the United States and it has to meet very stringent requirements. Capricorn Park was established in 1999/2000 as a technology and business oriented commercial estate and caters for mixed use: research laboratories, offices, clean manufacturing, limited warehousing and retail.

To manage a whole township is a totally different ball game. The management of the Wynberg industrial area has been, for a few years, the responsibility of the Wynberg Improvement District. It has been a voluntary city improvement district (CID) since 2001 and legislated in 2004. According to Lindie la Grange, business manager for Kagiso Urban Management, the Wynberg Improvement District approached Kagiso Urban Management to take over its management from April 2006. The CID works closely with the municipality in the management of this complex environment.

The main issues, according to La Grange, are safety and security, informal trading and the high pedestrian traffic through the area.

Capricorn Park was specifically planned and designed to cater for industrial and business use while Wynberg grew organically over a number of years, providing a livelihood for a broad variety of business enterprises.

Land use
Wynberg 6/10
*            Mixed land use
*            Motor-related industry

Wynberg is located in northern Johannesburg, wedged between the M1 and the high-density suburb of Alexandra. Crossing the M1 at Grayston Drive secures easy access to the very upmarket Sandton node. With industrial areas often located on the outskirts of the city, the locality of Wynberg has resulted in an interesting mix of businesses. Located so close to major residential areas, the industries are generally not major manufacturing or polluting enterprises. Recent developments in this area take the form of entrepreneurial small, medium and micro enterprises.

According to La Grange, there are 300 properties in Wynberg forming part of the CID and used by 216 individual businesses.

Although motor-related enterprises are probably dominant, a wide variety of land use is evident. This includes a call center for the Gauteng provincial government as well as a number of industries focused on interior decorating.

Being a ‘traditional’ industrial area, Wynberg also caters for land use supporting existing factories, ranging from informal cell-phone stands to formal food kiosks.

Capricon Park 8/10
*            Mixed land use
*            Strict control

The Capricorn site was undeveloped until 1999. Originally zoned for municipal purposes, it now has a zoning of ‘Commercial 2’ in terms of the municipality’s town planning scheme. All of the 82 industrial sites in the park have been sold and most of the existing sites are owned and occupied by the same entities.

The original idea was that Capricorn Park would cater specifically for small, technology and business development-orientated uses so a number of laboratories were established. Print technology-related uses are also found, as well as industry involved with technological research into motor-vehicle parts. At the entrance to Capricorn Park, there is a 5 000 m² retail node with a supermarket and other amenities.

The majority of the 64 office sites have also been sold. However the development uptake on them has not been as overwhelming as for the industrial stands.

Hartshorne is, however, optimistic about this part of the development as well, acknowledging the recent upturn in the commercial sectional title and letting market.

There are also future plans for another 6 000 m² mixed-use development and, further into the future, an upmarket residential and leisure-related land use to turn the estate into a truly mixed-use zone.

Accessibility
Wynberg 7/10
*            Pedestrian traffic
*            Close to highways

Wynberg is characterised by a high through-flow of pedestrians going towards and back from Alexandra but it seems that sidewalks do not always cater for their needs. The area is extremely accessible by motor vehicle with off-ramps from the M1 at the northern (Marlboro Road) and southern (Grayston Drive) ends of the ‘burb.

The Pan Africa Triangle – 12 ha between Alexandra and Wynberg – has been redeveloped as a taxi facility with associated retail and commercial developments.

In future, the nearby Gautrain station at Marlboro might also contribute to the accessibility of the area.

Capricorn Park 7/10
*            Contra-cyclical to peak hour traffic
            Accessible for workers

Capricorn Park is also easily accessible, especially in terms of traffic congestion that troubles the Cape Peninsula. Access is provided via the M5, the M3 and Baden Powell Drive. Traffic flow towards Cape Town is beneficially contra-cyclical.

In terms of the labour sources in the area, Capricorn is easily accessible from Mitchell’s Plain and Khayelitsha. Just north of the site is Vrygrond, an area that is reportedly one of the oldest former black townships in the Western Cape.

Workers from Vrygrond travel by foot. Rail commuting is also accommodated with the nearby Muizenberg and Retreat stations catering for Capricorn’s needs.

Sense of community environment
Wynberg 6/10
*            Buzzing with activity
*            Security concerns

The high densities prevalent in Wynberg, combined with large pedestrian traffic flows, give the area a vibrant and welcoming feeling.

A lot of things are happening simultaneously so a visitor gets a strong sense of community.

According to La Grange, issues pertaining to ‘crime and grime’ in Wynberg have improved tremendously since the CID appointed ’cleaning and safety ambassadors’.

These ambassadors are responsible for, among other tasks, sweeping sidewalks, removing illegal posters, graffiti and signage, as well as basic maintenance.

They also deal with crime – petty crime is predominant in this area.

Capricorn Park 6/10
*            Lack of activity
*            Sparsely populated

Capricorn Park still lacks a sense of community. This might be due to the fact that it is not yet fully-developed but it might also be ascribed to the low coverage of 50% that is required.

It is, however, a unique node that has the potential to grow and establish itself with a sense of community. The developers and managers are very concerned about working conditions and all of the individual property owners have to cater for their workers’ needs in terms of providing canteens and the like. The idea is that the conference centre will also increasingly serve as a community facility for the estate.

Environment
Wynberg 5/10
*            Litter
*            Possible pollution

Wynberg has no real environmental assets left except for a few trees along some of the sidewalks. A major concern is the amount of litter that is still found on sidewalks, open spaces and even on streets.

As with any industrial area, especially one so close to major residential suburbs, there is some concern about industrial pollution. The CID provides an ideal forum for self-control as it approaches the relevant property owners in the event of pollution. If no action is taken by the property owners, the CID alerts the relevant authorities.

Capricorn Park 9/10
*            High environmental standards
*            Harsh environment

Environmental concerns have probably been one of the major reasons for the establishment of Capricorn Park.

Increasingly, end users require compliance at source in the sense that manufacturing has to be environmentally-responsible.

Management of the park is, therefore, very strict about pollution of all kinds.

Located in an environmentally very harsh part of the Western Cape, special environmental care had to be taken during development. Of the 68 ha developed as part of Phase 1, 9 ha was exposed groundwater. The water bodies that form part of the attractive landscaping are continuously monitored. The proposed phases 2 and 3 of Capricorn Park also have plans for the development of a biodiversity corridor.

Development potential
Wynberg 6/10
*            Ideal locality
*            No clear vision

According to the City of Johannesburg’s regional spatial development framework for the Wynberg area (Region E), the area is ideally located to attract new business at various levels but the lack of available land and buildings is problematic.

The City of Johannesburg suggests that “efforts for enhancing the opportunities for industrial expansion should be linked directly to business incubation and small business/entrepreneurial development programming, and take cognizance of the proposed Gautrain station to be located in nearby Marlboro”. It is, however, not clear what the city has in mind for the future of the area.

Hopefully the continuous improvement and development of the nearby Alexandra might have a positive spin-off for Wynberg in future. According to La Grange, there are no vacant sites in the area and nearly no land is up for sale. This bodes well for the future.

Capricorn Park 8/10
*            Extensive future planning
*            Still under construction

Extensive plans are on the table for the future of Capricorn Park. Developers are in the process of obtaining planning permission for the second phase of the development, which will take place towards the south of the site, close to the sea.

Phase 1 is, however, still under construction and the real picture will only become clear as soon as construction has been completed.

A positive aspect for future development is that the estate is self-regulating and can (within limits) decide when to develop and where it would like to position itself.

Conclusion
Wynberg  30/50
Capricorn Park 38/50

Although Wynberg and Capricorn Park differ significantly in purpose, development history and general outlook, there are some points of similarity. Although there is space in the market for the traditional industrial area and the more hi-tech industrial development, these two ‘burbs could actually ‘learn’ some valuable lessons from each other.

INSPIRATION

Bright lights, big city
At night, Jozi’s skyline portrays the image of a world-class city.

The city of Johannesburg has an ambitious vision to become “a world-class city for all” that will “look and feel different from the city of the early 21st century”. No more dark corners and unsafe streets, Jozi’s vision is to be vibrant and home to an energetic night-life society. And we applaud the signs of Jozi’s international status – exemplary urbanisation.

The urban fabric is made up of various visual elements. Lighting is an important aspect of urban design and branding.

Whether natural or artificial, light accentuates genius, masks mistakes, grabs attention and makes a place feel sacred or safe. Or, as in downtown Jozi’s case, it can be inviting and hint at a vibrant night life.

But, of course, lighting is not only aesthetically pleasant. At street level, crime-ridden South Africa could benefit from more efficient lighting, as well as an active and vibrant night life.

On a global scale, NASA created a method of mapping urbanisation by using satellite images of the light generated by cities at night. With maps of city lights, NASA is now able to zero in on the impacts of urban sprawl on the food we eat, the air we breathe and the ecosystem we inhabit.

LED billboards on inner-city buildings and at the Top Star drive-in, south of central Johannesburg, hint at an active, investment-friendly and, above all, truly African and world-class city .Of course, a few light bulbs are not going to change the future character of a city, but lighting is a powerful design element and suggests a step in the right direction.

Imagine the possibilities!

INSULT

Bring down the masts
High-mast lighting is not the solution for sustainable settlements of the 21st century.

A walk around Vosloorus in the early hours of a winter morning is an eye-opening experience. High-mast lights shed an orange glow over the entire township.

Although it discourages night-time criminal activity, this type of lighting is probably more appropriate for industrial areas or major road intersections.

High-mast lighting is a remnant of the apartheid era but, surprisingly, it is still installed in present-day residential developments although government policy, like the ‘Breaking New Ground’ strategy, and other national and local policy documents, encourage environmental quality, human scale and neighbourhood character.

Bog-standard lighting solutions certainly don’t beautify rows of mass-produced houses. Sustainable human settlements require long-term vision. High-mast lighting is a shortsighted choice.

A well-known large banking group actually runs an advert to boast about how it helped a BEE contractor establish his own business installing high-mast lighting in townships. It is sad that the ‘new South Africa’ seems content with inhumane apartheid infrastructure while it strives to build worldclass, ‘integrated’ cities.

TREE OF THE ISSUE

Halleria lucida
A tree for small gardens
Willem de Frey, environmental manager and ecologist, discusses the Halleria lucida.

Halleria lucida, commonly known as ‘notsung’ or ‘tree fuchsia’, is a shrub of up to 3 m in height. It is an evergreen species, which occurs from Ethiopia in the north to the Western Cape. Its natural habitat is close to water, outcrops on grassy mountains slopes, wooded grassland and evergreen forests. It flowers from April to December and bears fruit from June to February, thereby giving colour to pale winter gardens while attracting birds in summer.

From personal experience, it grows well on the southern side of walls in small gardens. It is actually ideal for small areas and close to walls as its roots do not present a threat. With the inclusion of a few other species, it could be used to recreate the atmosphere found in forests – in your backyard!

According to literature, it grows up to 1 m per year and will withstand light frost. It hardly needs any nurturing and is not affected by common garden disease or pests. This species is actually ideal for the ‘low-impact’ gardener. It will not invade your garden as the flesh of the fruit contains a chemical that retards germination.

The species layers naturally and can be removed from the parent plant and transplanted. Cuttings must be made in early spring or summer.

Seedlings and young plants transplant well and are usually fast-growing. As is the case with most plants, it is better to get seedlings or young plants from plants that were grown at local nurseries.

Its fruits are edible. Flowers attract bees as well as sun birds while a variety of fruit-eating birds are attracted by the berries.
