Inthepast14years,low-incomehousingdevelopmentinSAhasbecomedominatedbytheproject-linked subsidy approach. In the case of informal settlements this is thecomprehensiveupgradingapproachthroughprovidingphysicalinfrastructure.Thisapproachis referred to as the conventional formal full upgrading approach and involves a once-offcapitalintensiveintervention,thecompleteredevelopmentofthesettlementinoneprojecttimeframe,demolitionof theexisting settlement, and redesigning the layout according tosetstandards.This,inalmostallcases,involvessignificantrelocationofresidents;forsomethe relocationwillbe temporaryand forothers itwillbepermanent.Suchanapproach isoftencriticisedforthemonotonousgrid-layout,withalowproportionofstandsperhectareandlittleattentionisgiventoaffordabilityandoperationalcosttomunicipalities.

the UISP, but can serve as a guideline. Plot sizes should emerge through a process ofdialoguebetweenlocalauthoritiesandresidents,takingintoaccounttheexistingbuildings,spaces, roads and pathways in the settlement. The provision of services should also beconsistent with the intervention categorisation. Community agreement on stand sizes,densities,levelsofservicesandprojectphasingisimportant.
Theplanningforeachsettlementbeginsatthebroaderstrategicor programmatic level. Each informal settlement should beplanned for at the strategic levelwithin the broader context oftheurbansettlementtheyarelocatedwithin.Eachsettlementshouldbeintegratedintothemunicipal planning and budgeting process in terms of the local municipal integrateddevelopment planning (IDP) and the spatial development framework in regional and localspatial frameworks or precinct plans. Once an informal settlement is assessed andcategorised, the category of intervention will inform what the most appropriate layoutapproachtobeappliedis.
At the settlement level a set of guiding principles should beagreed between the developer and the community before thelayout and infrastructure upgrading design commences.Dependingonthecategorisationofthesettlement,theguidingprinciplesshouldcoverthefollowingissues:
• Relocation,i.e.whoandhowmanypeoplegetrelocated;• Theextenttowhichtherewillbecompensationfortop-structurematerialsoreven
forlossoflivelihoods;• Levels of decision-making and community involvement and what degree of
autonomythecommunitywillhaveoverdevelopmentdecisions;• Political will and agenda, i.e. whether the local political representatives are truly
prepared tomake jointdecisionswith thecommunityorwhether there isahigherpoliticalagendatobemetaroundproposingimprovements.

foundations.• The 1-in-100 year flood line if applicable, within which no development can be
undertaken• Theavailabilityandproximityofbulkinfrastructureconnections.• Thesurroundingmaintransportroutes
All layout designs involve a series of trade-offswith advantagesand disadvantages. It is important to ensure broad communityconsensuson these trade-offs. Someof these trade-offs includeplotsizes/densities;plotorientationvshousedesignandpedestrianvsvehicularaccess.
The layout for an informal settlement upgrading project involves a relatively complextechnicaldesignprocessaimedatachievingthebestuseofspace,reducingrelocationsandmeetingcommunityrequirements.
Examples of approaches to layout include superblock layoutapproach,de facto layouts, re-blocking/blocking-out layoutsandrolloverlayouts.
Infrastructureapproaches
InSouthAfrica,therearethreebroadapproachesthathavebeenusedforserviceprovisioninurbanareas.Theappropriatechoiceofapproachshouldbebasedonananalysisofthecharacteristicsoftheinformalsettlement.Thethreeapproachesare:

• Ademand-drivenapproachwithvariablelevelsofservice.Servicesaredesignedtomeet specific needs and are not related to a structured hierarchy of incrementalimprovement.
A key point regarding service delivery is that according to theConstitution, local authoritiesare responsible for localplanningand service delivery. Thus, the range of services set out in thetable belowwill be provided in accordance with each individual local authority’s existingdelivery regime and mechanisms, procedures and capabilities. In cases where the localmunicipality is not in a position to meet their obligation there is room for negotiationbetweenaffectedcommunityorganisationsandthelocalauthorities.

Anotherkeyaspectofinsituupgradinglayoutsisthattheyshouldbeundertakenwiththeunderstandingthattheserviceswillbeupgradedandtop-structuresimprovedincrementally.This means that the layout should be designed in such a manner that the tenure andinfrastructure services can be improved over time without the layout having to beredesigned. As detailed below this is a fundamental departure from the one-size-fits-allapproachtolayoutplanningandinfrastructureprovisionforinformalsettlements.

• National norms and standards in respect of the

creationofservicedplotsdonotapplytotheUISP,butcanserveasaguideline;• Plotsizes:Thelayoutofinformalsettlementsgenerallyprecludesthedetermination
of uniform plot sizes. Plot sizes should emerge through a process of dialoguebetween local authorities and residents, taking into account the existing buildings,spaces,roadsandpathwaysinthesettlement;
• Service standards: The UISP provides funding for the installation of interim andpermanent municipal engineering services. Where interim services are to beprovided this must always be undertaken on the basis that such interim servicesconstitute the first phase of the provision of permanent services. The provision ofservicesshouldalsobeconsistentwiththeinterventioncategorisation;
• Participation: The nature and level of permanentengineering infrastructure must be the subject ofengagement between the local authority and residents.Communityagreementonstandsizes,densities, levelsofservicesandprojectphasingisimportant.Communityneedsmustbebalancedwithcommunity preferences, affordability indicators and sound engineering practice, aswellastheUISPsubsidyquantumandlevelofservicesprovided.

• Fromthismap,designaproposedmovementnetworkorpublicspacestructureusingtheexistingmovementsystemasabasisfortheproposedsystem;
• This results in a system of large land parcels or blocks defined by themovementpaths,containingmultiplehouseholdtop-structures;
• Formallysurveyandproclaimtheseparcelsorsuperblockstocreateastreet layoutandnewaddressesandstreetnames.Thesesuperblocksthenreceivesomeformofcollective/incremental tenure arrangement, i.e. administrative or legal recognition,forallthehouseholdswithinthem;
• This recognition, in turn, enables funding for some form of collective services e.g.standpipesandcommunaltoiletstobeinstalledperblock;
• Atalaterstagetheseblockscanbefurthersub-dividedandindividualtitleprovidedtoqualifyingbeneficiaries, followedby some formof individual household servicesbeinginstalled,e.g.yardtaps.
Example1:Superblocklayout:MonwabisiPark,CapeTown
Monwabisi Park (MWP) is an informal settlement of some 5 500 households locatedalong the southern boundary of Khayelitsha, Cape Town’s largest township. It wasformedin1997,whenpeoplebegantobuildshacksonanadjacent,unoccupiednaturereserve. Some 20 000 people, themajority from the Eastern Cape, now live inMWP.Although they are only 20 km from the central business district of Cape Town, mostMWP residents have yet to find an economic foothold. Some80%of households earnlessthantheminimummonthlysubsistencelevelofR1900.
The Indlovu Project began in 2005when the Shaster Foundation joined forces with alocal street committee leader and the founderof a small crèche thatbecame the firstIndlovu Centre building. In 2007, Worcester Polytechnic Institute (WPI) an Americantechnicaluniversity,beganworkingwiththeIndlovuprojectonaredevelopmentplanforthesettlement.

Thesuperblocklayoutapproachismoreapplicableinurbanareaswherethedensitiesofthesettlementsaregenerallyhigh,providinglimitedspacebetweentheexistingtop-structures.This approach is also most applicable to incremental upgrading i.e. Category B1-typesettlements for both tenure arrangements and infrastructure provision. As such thefollowingadvantagesanddisadvantages(prosandcons)ofthisapproacharesetout:
Pros Cons
• Superblocksarean in situapproachwhich results in minimaldisplacement as it uses existingpathways and roadways in thesettlement to define blocks andprovideimprovedaccessroutes.
• Layout can be undertaken quitequickly as one is not dealing withindividual household boundaries,rathersuperblocks.
• Rapid legal recognition can befacilitated for the settlement toreceiveinterimservices.
• The approach provides a spatialpattern and spaces for short-term/interim collectiveinfrastructureprovision.
• It is compatible with public financerequirements.
• It is ideal for incremental tenurearrangementsinthatthesuperblockcanprovidecommunallandsecurityin the short-term. Thereafter theycanbefurthersubdividedtoprovideindividual freehold tenure ifrequired.
• Superblocks may require somerelocation of residents for publicfacilities such as parks, schools,publicbuildings.
• Inappropriate layout for immediateindividual services installation andtenure arrangements, becauseindividual plot boundaries are notdemarcated around each top-structure.
Defactolayouts
This approach involves an in situ design based on the principles ofminimal disruption toexistingstructures,andinvolvesthefollowingsteps:
• Undertake a survey of each household to determine the residents’ perceived landboundaries,usingaGPS;
• Convert the GPS points into lines on a map. Some of these lines may overlap(indicatingthatthereisanoverlapinsomeoftheresidents’perceptionsoftheirland
In t roduct ion to In fo rma l Se t t lement Upgrad ing

i.e. dual claims to land) (see figure below). These lines also show the existingmovementsystemofpathwaysandroadsthroughthesettlement;
• Throughnegotiationwiththeresidentsagreeonhowtoadapttheexistinglinesintoindividual stand boundaries around each existing top-structure. At the same time,demarcate (set out space for) a minimum 5 m wide vehicular access strip alongexistingaccess routes through thearea.Wherenecessaryonemayonlybeable todemarcate2mwidepedestrianaccessstrips.Ensurethateachstandhassomeformofaccess.

Sec t ion 8 : Layout and In f ras t ruc ture , © NUSP 2015 19 | Page
This approach is most appropriate when the settlement is not too dense (i.e. mostlyindividual top-structures with a little yard around them). These types of densities arecommonlyfoundontheperipheryofthemetropolitanareas,andintheexpansionareaofsmall towns. This layout approach would be most appropriate for settlements beingupgraded including conventional formal full upgrading (Category A) and incremental fullupgrading (Category B1) as the layout determines the final road and plotsubdivisions/boundaries,facilitatingtownshipestablishmentandfullserviceprovision.
Someofthekeyconsiderationstobenotedwhenapplyingthislayoutapproachinclude:
• Desireddensityofresidentialstructuresperhectaretobeachieved,withagreementfromthebeneficiaries;
• Linked to the above, there should be pre-design agreements on the plot sizevariationspermittedgiventherangeoftop-structuresizes.
Pros Cons
• Minimal displacement of existingtop-structures.
• Duringtheplanningprocessthereisengagementwitheveryhousehold.
• Site by site engagement oftenresults in greater transparency andsupportfortheultimatelayout.
• Finalnegotiated layout canbeusedforfinalfreeholdtenureacquisition.

Re-blocking/blocking-outlayouts
Re-blockingorblockingoutisawayofimprovingtheplanningofinformalsettlements.Putmore simply, it refers to a re-arrangement of shacks in an informal settlement withcommunity consent. This form of layout focuses on the larger concept of spatialreconfiguration versus the simple delineation of sites i.e. the focus is not on individualhouseholdsandspace,butratheronthecommunalspacesusedbythewholecommunity.Thespacescreatedthroughre-blockingareusedforcommunalamenities,ortocreatelanesfor installation of services such as water, sanitation and electricity. It can also increasetenure security in the short-term and demonstrates community capacity with regard toplanning.

Therearevariationsinthere-blockingapproach,fromacomprehensivere-blocking(wherethe entire settlement is re-blocked) to the partial re-blocking approach (i.e. where onlythoseareasrequiringde-densificationforroads,healthreasonsandservicesinstallationarere-blocked).ThisisillustratedintheexamplesbelowofMshiniWamandRuimsig.

Mapping of the settlement for the re-blocking process was undertaken jointly byUniversity of Johannesburg students and communitymembers, through an agreementbetweentheuniversityandthecommunity.
Re-blocking is most appropriate in higher density informalsettlements, where de-densification is needed in order to installservices. It is also appropriate where the community and thedeveloper have decided to use this approach after considering theprosandcons(advantagesanddisadvantages)ofitsimplementation.
Someofthekeyconsiderationstobenotedforthere-blockingapproachinclude:
• What the final desired densities to be achieved will be. This must be done withagreementfromthebeneficiaries;
• Whether there-blocking isan interimmeasure for interimservicesorwhether it ispermanent. In both cases the boundaries around each top-structure need to beconsideredintermsoftheeventualtenurestatus.

• Compatible with public financerequirements.
• New fire-resistant metal structures,coupled with the creation of spacebetween rows of shacks, greatlyreducetheriskoffire.Thesespacesarespecificallydesignedtoallowthepassageoflargeemergencyvehicles.
• Soil compacting techniques appliedafterre-blockingandintroductionofgrading reduces the amount ofstandingwaterafterrainstorms.
• Large scope for local jobopportunities to undertake theprocess.
• Re-blocking facilitates anincremental approach by providingshort-termspaces intowhichaccessand interim services can beprovided, as well as communaltenuresecurity.
• Moving of top-structures couldresult in damage and therefore aneedforareplacementbudget.
• A re-blocking layout may make itdifficult to acquire freehold tenure,because no individual plots aredemarcated, rather largesuperblocks facilitating anincremental tenure securityapproach.

The N2 Gateway Housing Pilot Project is a large house building project underconstructioninCapeTown.ItisajointendeavourbetweentheNationalDepartmentofHuman Settlements, the provincial government of the Western Cape and the City ofCape Town. A private company, Thubelisha, has been outsourced to manage andimplementtheproject.Thubelishaestimatesthatsome25000unitswillbeconstructed,about70%ofwhichwillbeallocatedtoshack-dwellers,and30%tobackyarddwellersonthemunicipal housingwaiting lists.Manyof theseunitshavebeen completed.Due tolandavailability issues theproject is split into twoareas,a siteon theN2some15kmfromCapeTown,andasiteinDelft,some40kmoutsideofCapeTown.Tofacilitatethisdevelopmentsome20000 informaldwellers thathadpreviouslybeen livingontheN2sitehadtobedisplacedtotemporaryresidentialareas(TRAs)inDelft.
Initsearlyyears,theN2GatewaywascriticisedbytheGeneva-basedCentreonHousingRightsandEvictions,bytheSouthAfricanAuditorGeneral,bypopularorganisationssuchas theWestern Cape Anti-Eviction Campaign, by Constitutional Court experts such asPierre De Vos, and by affected residents themselves.

• Often results in the maximumefficient use of space and moreuniform/equi-sizedstands.
• It is often more cost-effective toinstall services due to straightservicelines.
• Fits with public financerequirements.
• Provides space for education andsocialfacilities.
• Growing shortage of well-locatedland (often the cause of blockedprojects).
• Vacant land often needs bulkinfrastructure which is extremelyexpensive.
• In accordance with minimum lotsizes these layouts are often verylow density, thus contributing tourbansprawl.This isexacerbated inareas of steep topography toaccommodate the cut and fillplatforms.
• In adhering to standards theselayouts often result in significantlevels of displacement of existingresidents(anotherfrequentcauseofblockedprojects).
• These layouts often negatecommunity participation becausethey are undertaken in areasremovedfromthecommunity.
• Little attention is paid to top-structureorientation.

2. Infrastructureapproaches
2.1 InfrastructuredeliveryapproachesinSouthAfrica
InSouthAfrica, thereare threebroadapproaches thathavebeen used for service provision in urban areas. Theappropriate choice of approach should be based on ananalysis of the characteristics of the informal settlement.These characteristics include economic and environmental sustainability and politicalimperatives. The first approach tends to be themost commonly usedbymunicipalities inSouthAfricaand ismostoftenapplied incasesof relocationorrollover interventions.Thethreeapproachesare:
• A high level of services. There are financial arguments against this option for lowincome communities.However, if communityparticipation indecision-making is tobemeaningful, demand for high level services can stem fromwithin communitiesand this demandneeds to be addressed effectively. This is particularly truewherethere isastronggrassrootspoliticalorganisation.Decentralisingdecisionsonpolicyneedstobeaddressedifthereistobelong-termsustainability.Thefuturestatusoftheareawithinawidermetropolitancontextmustbeaddressed,ratherthanlimitingthebasisofthedecisiononservicelevelstotheabilitytopay.Theabilitytopaymaybedefinedwithinahistoricalandartificiallydemarcatedgeographicalcontext.
• The progressive improvementmodel. Thismodel is similar to theaboveapproachexceptittakesamoreincrementalapproach,andupgradesservicesinatechnicallyrational and systematic manner. In theory there can be several entry points. Inpracticeitislikelytobeginwithbasicservices.
• Ademand-drivenapproachwithvariablelevelsofservice.Heretheemphasisisondeveloping the community in its widest sense, rather than focusing on capacitybuilding. There is a balance between the political and economic components ofdecision-making,betweenpolicyandimplementation.Thetechnicalaspectprovidesa supportive, rather than a determining role within the wider decision-makingprocess.Thecentral issue is thecommunity’s right tochoose,and that this right isnotgovernedsolelybythecriterionofaffordability.Insteadithastotakecognisanceof wider social and political factors. In this model, services are designed to meetspecific needs and are not related to a structured hierarchy of incrementalimprovement.
