The said layout will now be changed and Portion 30 of the Farm Lilyvale 2313 is now included as part of the township establishment. This document reports on the traffic impact of the whole area. The developer is as follows: Lenova Construction and Development Pty Ltd 4 Christo Groenewald Street. Lilyvale ` 5 1.3 Site Location The development is situated to the north of Hillsboro, and will access onto Bloemendal Road (extension of Rayton Road), and with possible future extension of the road network, also with Nicolai Street and De Vletter Street. Figure 1.1 Location Plan ` 6 1.4 Development The planned layout is shown below. Figure 1.1 Amended Layout It was endeavoured to as far as possible retain the approved layout of Extension 8 as shown below: ` 7 Figure 1.1 Approved Layout of Extension 8 Detail of the new layout is as follows: ` 8 From a practical point of view the land uses are as follows: Land Use Size Unit Note Extension 8 Single Residential Units 78 unit Townhouse Units 237 unit Shopping Centre 2000 m² 1 Cemetery 5866 m² Creche 50 pupils 2 Por 30/2313 Single Residential Units 128 unit Townhouse Units 58 unit Flats 358 unit Offices 3500 m² 3 Notes: 1. A shopping centre of 2000m² was assumed for Extension 8 in the approved layout and was thus retained. 2. It was assumed that the crèche will accommodate 50 pupils. This will not have a major implication 3. Offices will be restricted to 3500m², which is the practical development size ` 9 1.5 Scope of Analysis 1.5.1 Period for Analysis Based on the type of proposed development and the nature of traffic flow in the area, both the morning and afternoon peak periods need to be investigated. 1.5.2 Assessment Years As excessive Latent Rights are assumed and there is little chance of densification in this area other than the Latent Rights, a horizon year growth rate is not really deemed appropriate. To ensure a conservative approach, a growth rate of 1.5% was nonetheless assumed. The base year and five years after the base year have been analysed. The base year was assumed to be 2019. 1.5.3 Warrants for a Traffic Impact Study The change is expected to generate in excess of 150 peak hour trips and according to the “Manual for Traffic Impact Studies”1, a Traffic Impact Study is warranted. ` 10 1.5.4 Extent of Analysis All intersections where the increase in the critical lane volumes is expected to exceed 75, within 1.5 km of the development should be analysed. Given the location of the development, the following intersections were analysed.

All applied for developments, and more accurately rezonings or township establishments for which traffic impact studies have been compiled, are normally assumed to be anticipated developments. In this corridor the following latent rights are applicable. No Description Project Impact in No Study Area 1 Woodland Hills development 6017 No 2 Remainder of, and Subdivision 3 of Musket 2718, 6158 No 3 Shellyvale Extension 2 & 5 6154 Yes 4 Portion 2 and the Remainder of Portion 1 of the farm Mount Sophia 1441 6174 No 5 Plot 13 Lilyvale 6176 Yes 6 Portion 2 of Western Spitskop 6185 No 7 Plot 4, Rayton 6188 Yes 8 Joy 1401 6202 No 9 Portion 4 of the Farm Newmarket 2946 6197 Yes 10 Portion 2 of the farm Newmarket 2946 Yes 11 Remainder of Plot 28, Portion 1 of Plot 28, and Portion 2 of Rayton 341 6194 Yes 12(Rayton Portion 1View) of Plot 3 Raytion 6226 Yes 13 Township establishment on Portion 20 of the farm Lilyvale 2313, 6171 Yes 14 Township Establishment on Portion 2 of Plot 28, Rayton Smallholdings 6319 Yes 15 Township establishment on Plot 9 and the Remainder of Plot 12 Lilyvale 6528 Yes 16 Subdivision 29 of the Farm Lilyvale 2313 , Bloemfontein 6598 Yes 17 Erf 28563 Woodlands 6760 No 18 Rezoning to extend Curro School 6259 No 19 Erven 535 and 536 Shellyvale Extension 7 6154 Yes 20 Portion 45 of Farm No 2844, Groenvlei Function-, Facilities. 6978 No 21 Private University on Plot 27 Rayton 7097 No 22 Farm Rooidam (Emoya) Yes 23 Portion 1 of Plot 3, Lilyvale 6910 Yes 24 Erf 538, Shellyvale Yes In reality, only a portion of applied for developments actually realise as some are not approved, whilst a large portion of applications do not proceed to the final stage. In many instances land is zoned for development or an application was launched, but the main aim was to increase the value of land and not to actually develop the property. The implication is that developers keen to actually develop are “penalised” due to the need to consider all the latent rights. It is not possible to determine the status of each latent right, but to give an indication of the impact, scenarios were also developed to indicate the situation with no latent right trips. These scenarios were not fully analysed but in certain instances reference is made to the specific situation. ` 13 2 BACKGROUND INFORMATION 2.1 Existing Road Network The most important roads in the area are the following: Street / Road Road No Route Description Geometry Classific Functional Jurisdiction No ation Classification Frans Kleynhans Road S850 The road becomes Lucas Stayn Two-lane undivided Collector Collector Free State Province Road to the east of the N1.
