Facility densities and accessibility per nodeThe purpose with the SDF is to optimise access to facilities and minimisecost in sustaining service delivery. The previous sections identifiedsettlement focus areas in terms of population concentrations and generallocations. However, the presence of a large number of households doesnot necessarily define a priority for investment and support. .This sectionassess the major settlement focus areas in terms of access to facility andspecific facility density measured as the average number of householdsper facility..In a well-developed nodal system, one should expect that the highestdensity should be in the area closest to the nodal point. This is in line withnormal land rent theory and models of urban structure. In terms of theassessment, one would then expect the following: The largest number of households should be within the 10 minutesdrive time isochrone. The highest household densities should occur within the 10 minuteisochrone. The demand for facilities is a reflection of the number of potential usersand hence the number of households in its catchment area. In otherwords, the more fictions concentrated in the inner isochrone the higherthe central place function of settlement area. The lower the households per facility ratio in the inner core the higherthe central place functions of the settlement focus area.When these factors are considered Glencoe/Dundee is treated as singleentity. The following should be noted:1. Glencoe/Dundee serves the largest area within a 10-minute drive timefollowed by Nqutu. Tugela Ferry serves the smallest area because ofits topography and general inaccessibility to its immediateenvironment.2. Glencoe/Dundee service the highest number of households within its10 minutes zone followed by Nqutu with Greytown in third place butwith about 50% less households than Nqutu. Tugela Ferry is a closefourth and Pomeroy also serve a substantial number of households.Wasbank and Kranskop is by far the weakest in this part of theranking.3. Glencoe/Dundee has more or less the same number of facilities thanNqutu followed by Greytown and Tugela Ferry. Wasbank, Kranskop,and Pomeroy have very few facilities with Wasbank the weakest of thethree.Should one combine these factors then one get an indication of howstrong these areas are in terms of meeting the accessibility needs forsocial services.

Theassessment was based on drive times and it was earlier indicated that thepopulation is immobile and walk to access activities. The impact of walkingdistances needs to be assessed. The details for selected social facilities inthe table below show the impact of driving versus walking to facilities onthe access thresholds.The dark blue indicate the areas where the threshold density for walkingDraft 2013/14 IDP Review Page 199Prepared by Umzinyathi District Municipality22 March 2013
