1 Traffic Impact Assessment for Farm CA1020-RE - November 2016

1. INTRODUCTION

1.1 Introduction

Knight Piésold Consulting Engineers (Pty) Ltd. have been appointed by a private developer (Mr. Kieron Peter Taylor) to investigate and compile a Traffic Impact Statement for the proposed development of Farm CA1020-RE.

1.2 Location and extent

The land is located in the City of Cape Town area. Farm CA1020-RE, portion 0, remainder of farm Rocklands has an extent of 28,5 hectares. The site of the proposed development is situated on the Main Road (M4), 0,8km North of Miller’s Point and 4,2km South of Simon’s Town, Western Cape.

See Annexure A Locality Plan.

1.3 Property Information

Property Type: Farm

Farm Name: Rocklands

Portion Number: 0 (Remaining extent)

Local Authority: City of Cape Town

Registration Division Cape Rd

Province: Western Cape

Extent: 28,4456ha


2. CONCEPTUAL DEVELOPMENT FRAMEWORK

A Development Proposal for Farm CA1020-RE, City of Cape Town area, Administrative District of the Cape has been prepared by Michael Dall Architects. The proposed development comprises of the following:

Eight (8) Residential units - Residential

Two (2) Restaurants - Commercial

One (1) Cookery school - Commercial

One (1) Storage structure “Barn” - Commercial

One (1) Spa - Commercial

The development will be divided into the following land use areas:

Description No. of Floor area (m2)

Residential unit Three (3) 294.00 (98.0 each)

Residential unit Three (3) 248.46 (82.82 each)

Residential unit Two (2) 144.00 (72 each)

Spa One (1) 72.00

Barn One (1) 72.00

Restaurant/Lounge/Wine bar One (1) 507.54

Restaurant One (1) 72.00

Bar entrance One (1) 54.00

Cookery school One (1) 72.00

Kitchen One (1) 36.00

Total: 1 572.00

Table 2.1: Land Use Areas

2.1 Date of implementation

At present, no envisaged date of implementation can be established until such a time as all the approvals are in place.

2.2 Phasing of construction

The development of Farm CA1020-RE including all civil and building works will be undertaken in a single phase of construction.


3. PRIMARY STUDY AREA

3.1 Site access

The site is accessible via the Main Road (M4) which passes through Farm CA1020-RE with no adjoining roads, intersections or property accesses in excess of five hundred meters either side of the proposed access road for the development. No existing access road exists on the property.

3.2 External Roads

The proposed development of Farm CA1020-RE will not impact on any external roads in the vicinity of the property.

3.3 Sensitive Areas

No sensitive areas beyond those outlined in the environmental impact assessment have been identified. The property is in excess of one kilometre from the nearest residential address. The proposed development will be constructed in accordance with the City of Cape Town’s scenic drive network management plan.


4. EXISTING TRANSPORTATION FACILITIES

The only existing transportation facility serving the site of the development is the Main Road (M4) which is depicted in the photographs below

Image 1:

Main Road (M4). Provincial Road. Two hundred and fifty meters of the proposed access road on the northern approach. Single carriageway Speed limit: 60kph

Image 2:

Main Road (M4). Provincial Road. Facing northward from position of the proposed access road. Single carriageway Width of existing roadway: 7.8m Speed limit: 60kph

Image 3: Main Road (M4). Provincial Road. Facing southward from position of the proposed access road. Single carriageway Width of existing roadway: 7.8m Speed limit: 60kph


Image 4: General photograph.

Image 5: Main Road (M4). Provincial Road. Two hundred meters of the proposed access road on the southern approach. Single carriageway Width of existing roadway: 7.8m Speed limit: 60kph


5. CONFIGURATION AND OPERATION OF NEW ACCESS ROAD INTERSECTION WITH MAIN ROAD The new access road will intersect with Main Road at a right angled T-intersection in the location shown in the photographs contained in Section 4. The shoulder sight distance at the proposed location of the new intersection exceeds 250m in both the northern and southern directions. This means that there will be at least 15,0 seconds of sight time for a stationary vehicle entering Main Road from the new intersection for an operating speed of 60 km/h on Main Road and 11,7 seconds for an operating speed of 80 km/h. Both of these values are well in excess of the stipulated requirements and the intersection will thus operate without any safety concerns. The traffic volumes on Main Road are low enough that the intersection could operate satisfactorily without a southbound right turning lane and a northbound acceleration lane on Main Road. There is however sufficient space to provide extra lanes in the intersection and the final configuration will be determined at the detail design stage.


6. TRIP GENERATION

6.1 Daily Trip Generation Rates

6.1.1 Annual Average Daily Trip generation rates AADTD

Eight Residential Units = 4 per dwelling unit Restaurant, Cookery School and Spa = 90 per 100m2 GLA

(4*8) + (90*7.59) =715 trips per day generated

The trip generation of the Restaurant, cookery school and Spa is very likely to be considerably lower than 90 per 100m2 GLA due to their nature but this value is used in order to be conservative

6.1.2 Traffic factor FQD

Insufficient traffic volume data is available at the time of compiling the report to calculate this in accordance with TMH15.

6.1.3 Hourly Trip Rate (FQD x AADTD)

Insufficient traffic volume data is available at the time of compiling the report to calculate this in accordance with TMH15.

6.1.4 Percentage heavy vehicles PHD (of AADTD)

The available traffic data indicates that approximately 10% of all vehicular traffic using this route are heavy vehicles.


7. CURRENT TRAFFIC FLOW ON MAIN ROAD

7.1 Traffic Count

A 5 hour traffic count was carried out on 26 October 2016. The traffic flows measured represent approximately Level of Service A and thus there is a large amount of spare capacity on this road.

Based on the traffic count carried out on 26 October 2016, it appears that Main Road carries an Annual Daily Traffic (ADT) volume of approximately 100 vehicles per hour with approximately 10% heavy vehicles in each direction. The nature of the location being outside of the developed urban area is such that no peak hour can be defined

7.2 After Development Traffic

i) The total trip generation for the development has been calculated as a maximum

of 715 trips per day.


8. PROJECTED TRAFFIC FLOWS AFTER DEVELOPMENT

The Development is projected to produce a traffic flow of approximately 715 trips per day spread across a period of approximately 12 hours from 07h00 to 19h00. This results in an average of approximately 60 trips per hour or one trip per minute, which is however very likely to be considerably less in practice as stated in point 5.1.1


9. CONCLUSION

In view of the low volume of traffic generated by the proposed development and the spare capacity on the existing Main Road, which currently operates as Level of Service A, it has more than sufficient capacity to carry the total forecast future traffic including the additional trips generated by the development of farm CA 1020-RE
