Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 Transport Impact Assessment Proposed Filling Station on Erf 38333, Richmond Park, Milnerton This study summarises an investigation of the transport impacts, expected as part of a filling station development planned on Erf 38333, in the Richmond Business Park, Milnerton. This report forms part of an application to obtain 1 Purpose of Study development rights for this development. The purpose of this investigation is to identify potential constraints within the surrounding road network and to recommend appropriate mitigation measures, to ensure that acceptable future operations would be maintained. This development is planned on Erf 38333 in Milnerton, which is located in the north‐east quadrant of the Plattekloof Road / Upper Southern Precinct Boulevard intersection, within the Richmond Business Park. Existing Use: Vacant Erf 2 Locality and Extent Future Use: A filling station with five (5x) pump islands (10x pump bays) and a 330m2 total Gross Leasable Area (GLA) convenience store is proposed. See Figure 1 for a Locality Plan and Figure 2 for the Site Development Plan (SDP). The major roadways in the site vicinity include: Plattekloof Rd is a Class 2 Major Arterial road, with two lanes per direction separated by a median island. There is a sidewalk and cycle lane on the northern side‐ and a shoulder plus a sidewalk on the southern side. Tygerberg Valley Rd is Class 4 Collector, with two lanes per direction, with cycle lanes and sidewalks on both sides of the road, south of the Carmine 3 Existing Roadways Road / Lionel Solomons Boulevard intersection. Upper Southern Precinct Boulevard is a typical Class 5 road, with one lane per direction from the left‐in, left‐out access along Plattekloof Road, which opens up to two lanes per direction further north. There are sidewalks along both sides of this road. See Figure 1 for the location of these roads, relative to the development. There is currently no formal access to this site. See Section 13 of this report, 4 Existing Access for a discussion on the proposed future access/es. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 1

Weekday AM peak hour (Surveyed peak hour 06:45 to 07:45) 6 Analyses Hours Weekday PM peak hour (Surveyed peak hour 16:30 to 17:30) The peak hours were determined from the peak period traffic counts. Scenario 1: 2021 Existing Traffic conditions. Based on 2021 traffic counts, escalated with a growth rate (13%/2% AM/PM), PLUS an additional two percent growth rate per year over two years, to compensate for the lower than “normal” traffic volumes, due to the impact of Covid19 Lockdown Level 1 on traffic flows. See Section 8 of this report for more details. Scenario 2: 2024 Background Traffic conditions. Based on Scenario 1 traffic volumes, escalated with a two percent growth rate over three years PLUS the 7 Scenarios Analysed trips from other approved / in‐process developments added onto the surrounding road network. See Section 10 in this report for more details. Scenario 3: 2024 Total Traffic conditions. Based on Scenario 2 traffic volumes, PLUS the trips from the proposed filling station. See Section 14 of this report for more details. Intersection analyses were done with Traffix version 8.0 Software, which is based on the Highway Capacity Manual (HCM). INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 2
Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 Peak hour traffic counts were done on Tuesday, 23 February 2021 during the Covid‐19 Level 1 lockdown period. These 2021 counts were compared with Sept. 2019 traffic counts and found to be 13% and 2% lower than the 2019 traffic counts, for the weekday AM‐ and PM peak hours respectively. Hence, the 2021 counted traffic volumes were escalated with these growth rates, PLUS an additional two percent growth rate was added per year over the two‐ year period, to determine the calculated 2021 Existing Traffic volumes. These 2021 traffic counts were done, to identify changes in traffic patterns and turning movements at intersections since 2019, due to changes in the road network, such as the completion of the Giel Basson Drive link (completed mid‐2020). This calculated 2021 peak hour traffic volumes was used for the Existing Traffic capacity analyses. Site visits was also done in March 2021, during the peak traffic periods. The following was observed during these site visits: Plattekloof Roundabout: The southbound right‐turn movement were relatively busy during the AM peak period, although the roundabout operated acceptably. A number of cyclist were observed along Tygerberg Valley Road / De 8 Existing Traffic – Grendel Road, through the Plattekloof roundabout. Scenario 1 The 2021 Existing Traffic conditions are based on the calculated traffic volumes as well as the existing intersection geometries and controls. Based on the Existing Traffic capacity analysis results, the following are concluded: Most study intersections currently operate acceptably. However, the following intersection experiences constraints and require upgrades: Int. 1 Plattekloof Road / N7 Western Terminal: currently operates at unacceptable Levels‐Of‐Service LOS E / F, delays greater than 50 seconds and Volume‐to‐Capacity (v/c) ratios of 86% / 97% during the AM / PM peak hours respectively. Relatively long delays and queues are experienced on the north‐ and eastbound approaches of this intersection. Recommended Upgrades: Based on communication received from the Western Cape Government, the Refinery Interchange upgrade is scheduled to commence in September 2021. These upgrades will include the following, as illustrated schematically on Figure 4C: Eastbound – a separate left‐turn lane plus two through lanes. Westbound ‐ a separate right‐turn lane plus two through lanes. Northbound – two right‐turn lanes plus a left‐turn slip lane. Operations after Upgrade: Acceptable Levels‐Of‐Service A / B. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 3
Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 As part of this Refinery Interchange upgrades, the Plattekloof Road / N7 Eastern Terminal will also be upgraded, to include the following: Eastbound – two through lanes. Westbound – two left‐turn slip lanes plus two through lanes. Southbound – separate left‐ and right turn lanes. Operations after Upgrade: Acceptable LOS A during both peak hours. See Figure 4A/B for the 2021 Existing Traffic volumes and operations summary for the weekday AM and PM peak hours respectively. Also see Figure 4C for the operations after the Refinery Interchange upgrades. The trips from the following Approved / In‐Process developments were included in the Background‐ and Total Traffic conditions scenarios: CTM, Erf 38308 CFC, Erf 38310 RPP, Erf 38313 Panorama Light Industrial Park, Erf 38320 (4 Lease Areas) Hume, Erf 38317 Sales Office / RPMPOA Office, Erf 38239 9 Approved / In‐ Mustek Development, Erf 38311 Process Future Development Rem Erf 38235 Developments Richmond Corner, Erf 38332 ACDC Dynamics, Rem Erf 38234 (Lease Area) Corex, Rem Erf 38234 (Lease Area) Astron Energy, Rem Erf 38236 Aramex, Erf 38345 Get Worth, Erf 38331 Takealot Rem Erf 38394 (Lease Area) These Approved / In‐Process developments are expected to generate an additional 1 356 peak hour trips, on the surrounding road network. The 2024 Background Traffic volumes were calculated by applying a two percent growth rate per year over a three‐year period, to the calculated 2021 Existing Traffic volumes, PLUS the trips from the other approved / in‐process 10 Background developments, as summarised in Section 9 of this report. Traffic Scenario 2 The analysis in this scenario is based on the existing intersection geometries and control, plus the upgrades planned at the Refinery Interchange, as discussed in Section 8 of this report. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 4
Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 Based on the 2024 Background Traffic capacity analyses, all study intersections would continue to operate at acceptable Levels‐Of‐Service, with the existing geometry plus the upgrades planned at the Refinery Interchange. Hence, no additional road upgrades are required or proposed for the 2024 Background Traffic conditions, from an intersection capacity point of view. See Figure 5 for a summary of the expected 2024 Background Traffic volumes and operations. Filling stations mostly intercept / capture pass‐by / diverted trips that are already on the road network surrounding a site. Although some (nett‐) new trips are also expected, this percentage is typically relatively low for filling stations. The pass‐by / diverted‐, nett‐new and total trips for this development was calculated as follows: The South African Trip Generation Rate (SATGR) manual recommends a 4 percent total capture rate of traffic volumes on the surrounding road network, and recommends that 16 percent of this total captured volume are net‐new trips. The above percentages and recommendations are based on old data. Hence, a rethink of these percentages is proposed, as agreed by CoCT officials. The following methodology was used to calculate this filling station development trips: o The Filling Station and Convenience Store trips were calculated separately. 11 Trip Generation o Filling station = apply a 3% total capture rate (Based on the 2001 and Development Paper “Revision of the Guidelines for Access to Filling Stations in Trips the Greater Pretoria Area”). All filling station trips to be evaluated as pass‐by / diverted trips. o Convenience Store = The total GLA of the C‐Store is 330m2. However, the trip generation is based on the retail floor space only (i.e. 200m2 rounded value). The office, storage, ablutions facilities, ATM and refuse areas were included as part of the filling station trips, as agreed with CoCT officials. The relevant pass‐by (13%) and diverted (29%) percentages were also applied. o Shared Trips = since the trips are calculated separately for the different land‐uses and since some shared trips are expected, a 10.4% shared trip reduction factor is recommended. (Based on the 2001 Paper “Revision of the Guidelines for Access to Filling Stations in the Greater Pretoria Area”). Based on the above methodology, this Filling Station and Convenience Store is expected to generate the following peak hour (pass‐by / diverted / nett‐ new and total) vehicle trips: INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 5

The majority of these trips will be intercepted / captured trips, with only a few nett‐new trips being generated by the convenience store. This development is expected to generate 24 total nett‐new trips during the weekday PM peak hour and only 20 nett‐new trips when including the 15% Public Transport reduction, as agreed with CoCT officials. See Figure 6 for the expected intercepted / generated development trips and the distribution of these trips through the surrounding road network. The following trip distribution was used for the C‐Store nett new trips: 20% of trips to / from the south along De Grendel Avenue. 20% of trips to / from the east along Plattekloof Road 30% of trips to / from the west along Plattekloof Road 5% of trips to / from the east along Carmine Drive 12 Trip Distribution 5% of trips to / from the east along Burgundy Drive 5% of trips to / from the east along Sienna Drive 15% of trips to / from the north along Tygerberg Valley Road The pass‐by, diverted and interception trips will occur based on the existing peak hour traffic patterns experienced along the surrounding road network. See Figure 6 for a graphic illustration of this expected trip distribution. Two accesses are proposed as part of this filling station development: A Full Access ‐ from the Mall Access Road, approx. 25 meters east of Upper Southern Precinct Blvd. A dedicated eastbound right‐turn lane is recommended from this access road, into the filling station. 13 Site Access A left‐out only exit to Upper Southern Precinct Blvd, approx. 30 meters north of Plattekloof Road. See Figure 2 for the locations of these accesses and Figure 7 for a schematic illustration of the lane configurations and controls at these accesses. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 7
Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 The 2024 Total Traffic volumes were calculated by adding the expected filling station development trips (including pass‐by, diverted, intercepted and nett‐ new trips) to the 2024 Background Traffic volumes. The geometry used in this scenario is based on the existing intersection geometries (see Figure 3), plus the upgrades planned at the Refinery Interchange (See Figure 4C), plus the access / intersection upgrades recommended as part of this filling station development. (See Figure 7). Based on the capacity analyses results, all the study intersections are 14 Total Traffic – expected to continue to operate at acceptable levels‐of‐service, during the Scenario 3 peak hours analysed. Hence no additional upgrades are required as part of the filling station development. However, a single lane roundabout is proposed at the Upper Southern Precinct Blvd. / Mall Access Road intersection, to ensure acceptable long‐ term operations. This intersection would operate acceptably as part of the filling station development with the existing geometry and control, but this upgrade is proposed, to mitigate disruption of traffic flow in the future. See Figure 8 for the 2024 Total Traffic volumes and operations Existing Facilities: Plattekloof Road is a Class 3 cycle route and Tygerberg Valley Road is a Class 4 cycle route, according to the City of Cape Town’s NMT network plan. See Figure 9 for an extract from this CoCT plan. The following facilities are currently available in the immediate site vicinity: Sidewalks along both sides of Upper Southern Precinct Blvd, along both sides of Plattekloof Road, along both sides of Tygerberg Valley Road, and along the northern side of the Mall Access Road. Cycle lanes along both sides of Tygerberg Valley Road / De Grendel Road as well as along Plattekloof Road from the Refinery Interchange Eastern Terminal to Upper Southern Precinct Boulevard, along the 15 Non‐Motorised northern side of the road. The relative wide shoulders along the Transport remainder of Plattekloof Road are also used as bicycle lanes. Pedestrian crossing at the Upper Southern Precinct Blvd / Southern Precinct Blvd roundabout, at the Plattekloof / Tygerberg Valley roundabout and across Upper Southern Precinct Blvd, north of the Mall (and future filling station) access. There are median islands along most of the study roads in the site vicinity, which enable pedestrians / cyclist to cross one traffic stream at a time. See Figure 10 for the locations of these existing pedestrian / cyclist facilities. During the site visits it was observed that some cyclist and pedestrians use these facilities. The existing hourly pedestrian‐ and cyclist volumes are illustrated on Figure 11. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 8
Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 Proposed Facilities: The following pedestrian facilities will be provided, as illustrated on Figure 2, the Site Development Plan: A sidewalk on the southern side of the Mall Access Road. A walkway between the Mall Access Road and the convenience store pedestrian access. This walkway would accommodate pedestrian movements between the parking areas and the convenience store. A ramp at the disabled parking bay in front of the C‐Store access. These above proposed facilities together with the existing sidewalks and cycle lanes in the site vicinity, should be sufficient to accommodate the expected pedestrian movements to / from this filling station development. Existing Facilities: See Figure 12 for an extract from the City of Cape Town’s Public Transport Network Plan. Based on the figure, the following roads in the site vicinity are currently used as public transport routes: Tygerberg Valley Road / De Grendel Drive – IRT, Taxi and bus routes. Plattekloof Road – West of Tygerberg Valley Road are taxi‐ and bus routes, and East of Tygerberg Valley Road is only a taxi route. The following facilities are currently available in the site vicinity: Taxi embayment on the western side of Upper Southern Precinct Boulevard, just north of the Mall Access Road. Taxi embayments north and east of the Upper Southern Precinct Boulevard / Southern Precinct Blvd roundabout. Taxi embayment east of the Lionel Solomons / Upper Southern Precinct Boulevard roundabout. Bus embayments along Tygerberg Valley Road, on the downstream 16 Public Transport side of the Lionel Solomons Drive / Carmine Drive intersection. A taxi rank (for 10 taxi bays) on‐site at the Mall. See Figure 13 for the locations of these public transport facilities as well as surveyed peak hour public transport volumes. Future Planning: Several additional taxi embayments are going to be implemented at the downstream side of intersections, as part of the larger Richmond Business Park internal road network. An IRT facility and service is also going to be implemented along Tygerberg Valley Road, at the downstream sides of the Carmine Drive‐ and Burgundy Drive intersections. Proposed Facilities: The proposed filling station development is not expected to generate a significant number of public transport trips. The existing and planned future public transport facilities would be sufficient to accommodate the expected public transport demand of this development. Hence, no additional public transport facilities are proposed as part of this filling station development. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 9
Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 On‐site parking should be provided according to the rates recommended in the “Minimum Off‐Street Parking Requirements” from the City of Cape Town. See Table 7 below for a summary of the required on‐site parking bays: Table 7: Parking Required # Bays Land Use Recommended Parking Rate Required 17 Parking Filling Station 1 bay / pump (based on 10 pump bays) 10 bays 2 2 Convenience Store 4 bays / 100m (based on 330m GLA) 13 bays Total 23 bays Based on the above summary, a min. of 23 parking bays should be provided on site. According to Figure 2, the Site Development Plan (SDP), 41 parking bays would be provided. Hence, sufficient on‐site parking would be available. The on‐site circulation was evaluated. The fuel tanker would enter the site from the Mall Access Road and it would exit the site via the left‐out exit along Upper Southern Precinct Boulevard. The offloading to fuel will occur on the 18 Site Circulation left‐hand side of the truck. The truck movement is illustrated schematically on Figure 2 the Site Development Plan (SDP). Based on this investigation, acceptable on‐site circulation would be possible for all vehicles. Several road link, intersection‐ and interchange upgrades are planned in the vicinity of this development, as summarised below and shown on Figure 13. The extension of Giel Basson Drive – (already) completed mid‐2020. Refinery Interchange (Plattekloof Road / N7 Freeway Terminals) – Reconstruction scheduled to commence in September 2021. Extension of Burgundy Drive, between Tygerberg Valley Road and Koeberg Road, across the N7 Freeway – construction of the section across Richmond Park to commence before end‐2021. Dualing of Tygerberg Valley Road, between Carmine Drive and 19 Future Road Burgundy Drive – expected to commence in 2022. Network Extension of Carmine Drive to the future Blaauwberg Road extension‐ Note, approx. 70% of this road link is already constructed. New Blaauwberg interchange, including a link road between Koeberg Road and the re‐aligned Tygerberg Valley Road. – date unknown. These link upgrades are expected to result in changes to the existing traffic patterns and distribution. It is likely that once this full road network is in place, that the traffic volumes along Tygerberg Valley Road could reduce. However, the remaining development potential in this area might again take up the available spare capacity, resulting in similar traffic volumes (than evaluated in this report) along the study road sections.

Proposed Filling Station on Erf 38333 April 2021 Revision 1 ITS 4330 This study summarises an investigation of the transport impacts, expected as part of a filling station development planned on Erf 38333, in the Richmond Business Park, Milnerton. This report forms part of an application to obtain development rights for this development. Based on the findings of this investigation, the following can be concluded: Land Use / Extent – A filling station with five Pump Islands (10 pump bays) and a 330m2 Gross Leasable Area (GLA) Convenience Store. Existing Traffic Conditions – The western terminal of the Refinery interchange currently operates at unacceptable Levels‐of Service during the peak hours. Upgrade of this interchange will commence in September 2021. This interchange would operate acceptably, once this upgrade in in place. Background Traffic Conditions – All study intersections are expected to continue to operate acceptably. Hence, no road upgrades are required or proposed in this scenario. Trip Generation – 83‐ / 160 total trips would be captured / generated during weekday AM / PM peak hours respectively. Only 24 nett‐new trips would be generated during the PM peak hour or only 20 nett‐new trips when including a 15% Public Transport reduction, as agreed with the City of Cape Town officials. 20 Conclusion & Vehicular Access – A full access is proposed from the Mall Access Road Recommendations and a left‐out only exit is proposed from Upper Southern Precinct Blvd Total Traffic Conditions – All study intersections are expected to continue to operate acceptably. Hence, no road upgrades are required for this scenario. However, a single lane roundabout is proposed at the Upper Southern Precinct Blvd. / Mall Access Road intersection, to ensure acceptable long‐term operations. Pedestrian and Cyclists – The following facilities will be provided: o A sidewalk on the southern side of the Mall Access Road. o A walkway between the Mall Access Road and the Convenience Store pedestrian access. o A ramp at the disabled parking bay in front of the C‐Store access. Public Transport – No additional public transport facilities are proposed as part of the filling station development. Parking – Sufficient parking would be provided on site. Site Circulation – Acceptable on‐site circulation would be possible. Based on this investigation, it is evident that the expected transport impacts from the proposed filling station development on Erf 38333 could be sufficiently mitigated, provided that the upgrades as discussed in this report are in place. Hence, it is recommended that this development be considered for approval, from a transport point of view. INNOVATIVE TRANSPORT SOLUTIONS (PTY) LTD Page 11
