Methodology
The methodology in the report included:
A site visit to observe current travel patterns, road geometry and to gain an
understanding of the study area,
For the purpose streamlining the contents of this report, the analysis shall of the
site shall be separated into 4 developmental portions linked to the wards, being:
→ North-east portion on Ward 2 to be Sub-Development A
→ South-east portion on Ward 4 to be Sub-Development B
→ South-west portion on Ward 6 to be Sub-Development C
→ North-west portion on Ward 1 to be Sub-Development D

Accessibility to site and Road Classification
Road network master-planning
The road network adjacent to site are N14 and R30. R30 was previously owned by the provincial road authority but now is taken over by SANRAL. There is no master plan for the area.
Road classification, design speed and design vehicle
5.2.1. Road Classification
For this report, road classification is very important for analysis of the traffic parterns within the vicinity of the site. The roads classification is accorrding to COTO - RCAM a) N14 Highway currently is operating as – Class R2 (Rural major arterial) which will
in future become Class R1 (Principal Arterial). b) R30 is in general classified as Class R2 (Rural minor arterial). R30 to the north of
N14 links Ventersdorp and Rustenburg at approximately 95km, to the south of N14 links Ventersdorp and Klerksdorp at approximately 70km
- It should be noted that R30 to the north from N14 goes into Ventersdorp Town and this 4.5km section of the road shall not have functions of a class 2 road, it shall operate Urban Class 3 and 4a.
- R30 to the south shall be R2 however the first 2km section from the N14 shall be operating as Class U2
5.2.2. Design Speed
N14 = 120 km/h R30 to the south = 80 km/hr first 5km section from N14 R30 to the south = 120 km/hr over 5km section from N14 R30 to the north = 70km/hr

Road Access, Intersection Provision and Spacing
- Full intersection shall be provided for all sub-developments with R30 being a priority road.
- There is an access position approved at approximately 600m to the north of N14 along R30 which is meant to provide an access to Tshing Village and proposed sub-development D. A symmetrical intersection is therefore proposed to provided an access to the proposed sub-development A. Also a second linkage on the northern part of the sub-development A is proposed. This second linkage shall link with the intersection to Tshing Village.
- A symmetrical intersection to sub-developments B and C is proposed to the south of N14 along R30. Since this intersection is new, it will require a spacing of 800±15% along R30 from N14 intersection.
- Internal Class 4a, 4b and 5b intersections to be spaced at a minimum of 100m, 75m and 50m respectively.

- Sub-development A: 2 intersections are proposed off R30 to provide access. The
intersections are denoted as Y and Z on figure 2 below.
- Sub-development B and C: intersection is proposed off R30 to provided access to
these two sub-developments. The intersection is denoted as X on figure 2 below.
- Sub-development D: This development shall obtain access of an existing
Letsibaba Street.
9.1.2. Impact of site access on adjacent properties
- All the sites access does not affect the neighbourhood accesses.
Recommended access layout and control from the road
From above summary of intersection analysis results, it is recommended that all-way stop
control be provided to better the operating conditions for the site access.

Road Widening, PWV Network and Servitudes
Road widening & PWV Network
a. Municipal Roads: No widening required. b. Provincial Roads: Site is not affected. c. SANRAL Roads: Site is not affected. See Annexure F for PWV Road Network.
Servitudes
- Internal road servitudes in accordance of the road classes shall be registered to the
satisfaction of the municipality. - External and internal splays to be registered to the satisfaction of SANRAL and
Municipality respectively. - Servitudes for road connection network to the neighboughing properties shall be
registered to the satisfaction of the Municipality.
Public transport assessment
In terms of the National Land Transport Act (NLTA) (Act No 5 of 2009) Section 35,
assessment of public transport should be included in the traffic impact assessments.
The following comments are relevant in respect to the public transport availability at
the proposed development.
a. Public transport
- R30 Road is a transit road comprising of mini-buses (taxis) and buses.
- It is proposed that the one stand zoned Municipal in Sub-development C shall be
allocated to taxis as a small taxi holding and rank. This taxi rank shall have
dedicated route within Sub-developments B and C.
- The site shall therefore be well serviced by Public Transport.
b. Non-motorized transport
- A 1,5m paved side-walk is therefore proposed to be constructed on the internal roads in accordance with the Municipal standards at the properties frontage to cater for NMT.
Vtdp N14 Dev– TIA (V1) 23
Parking requirements
- There is a conceptual Site Development Plan prepared which is not yet finalized, however, the parking shall be provided internally as per the town-planning scheme.
Summary and Recommendations
In summary:
- This TIA report is prepared to support a Township establishment in Ventersdorp
area, situated at the intersection of N14/R30. - The methodology of approaching this development TIA was sub-dividing
development into four sub-developments i.e A, B, C and D situated at NE, SE, SW and SE of N14/R30 intersection respectively.
- Land use township application is in cicrulation seeking an approval of the following rigths on sub-developments:

4. PROPOSED IMPLEMENTATION PROGRAMME
In order for the project to be implemented within reasonable time frames, the following
Implementation Programme is proposed for adoption by the Client.
It needs to be noted though while we will take every reasonable effort to ensure that the
Project is delivered within the stipulated timeframe, a greater
proportion of the implementation time will be taken by the respective approving authorities
which too often do not consider these kinds of applications within
the statutory time frames. Our role in this regard will be a continuous persuasion of these
approving authorities for speedy approvals.

5. DATA SO FAR COLLECTED
5.1. TOWN PLANNING INFORMATION
The Township Establishment process will start with data collection. The following information
has so far been collected:
Cadastral information on the subject property
Obtained title deeds and will later assess any restrictive conditions (if any) for the
subject property;
Obtain strategic planning and related documents. These documents have so far been obtained
from the Municipality:
The Ventersdorp Municipal Integrated Development Plan (IDP) 2016-2017
Spatial Development Framework (SDF) 2010
Draft Local Economic Development (LED) Strategy 2015
Draft Housing Sector Plan (HSP) 2014
Dr Kenneth Kaunda District Municipality IDP and sector plans
National Spatial Development Plan (NSDP)
Provincial Growth and Development Strategy (PGDS)
These documents are currently being reviewed and analyzed in order to establish the
development vision and planning principles for the Study Area.
The review and analysis of the documents will also assist with both vertical and horizontal
alignment.
5.1.1. INFORMATION GAPS
It is important to indicate that, Ventersdorp Local Municipality was disestablished and merged
with Tlokwe City Council Local Municipality to establish
JB Marks Local Municipality on 3 August 2016. Most of the information available is historical
in nature and relates to the municipality before being disestablished.
As a result of the disestablishment, a number of key strategic documents are in a draft form
and have not yet been approved by council as official documents.
Other documents are outdated and need to be reviewed as per the applicable legislation.
The following information gaps were identified during this initial data collection stage:
13 | P a g e
1. Socio Economic study/ Market assessment will be required as it will inform the housing
product type, affordability and percentage allocations.
2. The municipality has the waiting list which is not used as it is considered unsatisfactory
as a result, the extend of housing demand/ backlog cannot be established.
3. The alternative to establishing demand is use the Provincial Demand Data Base which
must be informed by the municipal waiting lists
4. The Informal Settlements Upgrading Programme (ISUP) report was compiled in 2008,
this report provides an overview of informal settlements identified within Ventersdorp.
Informal settlements have direct bearing on the provision of housing
5. SDF was last approved in 2010, and should have been reviewed after five years as
required by the Municipal Systems Act (No. 32 of 2000) as it forms a significant part of
key strategic documents for the municipality
6. Housing Sector Plan 2014 is still in a draft format, therefore, there appears to be no
approved Housing Sector Plan in place;
7. The LED Strategy is also still in a draft form.
5.2. SITE VISIT WITH MUNICIPAL OFFICIALS
A preliminary meeting with both Municipal and HDA officials took place in Potchefstroom on
the 10th October 2017 in order to introduce our Team to the municipality. After the meeting a
site visit and walk about with the entire project team and municipal officials followed on
Monday, the 16th October 2017 in Ventersdorp.
5.3. ENVIRONMENTAL INFORMATION
The focus of attention for this part of the project will be on the following, namely:
undertake the flora & fauna assessments,
undertake the Wetland/ riparian delineation & functional assessment merged with the
Soils & Agricultural Potential, so as to provide high level input into the Wetland
Sensitivity and Extent w.r.t the project site, with the aim to determine no-go areas and
sensitive landscape elements, and
undertake a heritage impact assessment,
14 | P a g e
lastly, expedite the socio-economic survey, in order to develop the following: Socio-
Economic Profile & the Socio-economic Needs Assessment
5.3.1. SITE VISIT OBSERVATIONS(ENVIRONMENTAL)
The following observations were made during our site visit as at week of 16 to 22 October
2017
It can be noted that we are aware that Venterdorp has been plagued with service delivery
protests, included in there is a cry for housing provision by the community. In order to address
the matter, note Council earmarked land parcels under its auspices for housing development.
It is unfortunate, that council did not provide us with alternative farmland parcels that had
lain as not ploughed for consideration. Nonetheless, from an ecological point of view, it can
be noted that there are site sensitivities flagged hereunder with regards to the earmarked
project sites and the Client is given a heads up that buffering will endeavour to bring resolve,
that goes for heritage as well.
Key environmental features discerned on site:
a watercourse that meanders gently through the middle wherein the two farms meet (see
outline figures on the google image). Another gently winding channel can be seen east of
the Remainder of the farm Elandskuil 206-IP. All sensitive sites will be rehabilitated and
be zoned Public Open Space.
there are graves close to the north-western boundary of the Remainder of the farm
Elandskuil 205-IP. In terms of town planning they will not be disturbed as it has been
planned that they be demarcated & zoned public open space for usage by family members
of those buried (NB: - usage will be limited to allow visits to graves, paying homage &
cleaning thereof). Whereas, to the north of the Remainder of the farm Elandskuil 206-IP,
there is JB Marks Memorial site (consisting of his inscribed granite plate, grave & statue),
after whom the new Vendersdorp municipality name has been officially changed. Thus as
a further consideration from a Heritage point of view they will be buffered accordingly.
Tshing township lies immediately to the north of the development site.
Arterial routes depicted is the N14 to & from Krugersdorp & Lichtenburg bearing in
an east west direction, whereas going from north to south (i.e. from small town Derby
through Ventersdorp town to Klerksdorp is the Provincial road the R30).

CONTOUR INTERVAL :0,50m
SCALE 1:1000
5.5. ENGINEERING SERVICES
ASSUMPTIONS
This report is prepared with the understanding that the information provided by the JB Marks
Local Municipality’s technical division is correct.
5.5.1. SCOPE
The scope of work for the bulk engineering services investigations conducted can be
summarised as follows:
Provide a topographical and geological overview of the study area;
Investigate the study area(s) storm water drainage;
Investigate the presence and current operational capacity of bulk engineering
services infrastructure in terms of potable water supply, sanitation, electrical supply;
Investigate road access to the study area;
Investigate the presence of solid waste disposal facilities to service the proposed
development;
16 | P a g e
Conduct a study area slope analysis to determine which portion(s) of the study area
are may be undevelopable;
5.5.2. TOPOGRAPHY AND DRAINAGE
The study area has an average height of 1465 meters above sea level and is dominated by
gentle to fair slopes with average gradients of 1.3% on portion 205 IP and 5% on portion 206
IP draining south towards the Skoonspruit River. Due to the study area being dominated by
gentle to fair gradients, storm water drainage problems and or any developmental constraints
associated topographical gradients are not foreseen. However, storm water management
measures should be incorporated into the study areas development to reduce and or eliminate
any potential risks to life and property that may be posed by storm water runoff.
Storm water management objectives and mitigation measures highlighted below may be used
as a guideline in the planning and design stages of proposed development(s) on the study
area.
5.5.3. STORM WATER MANAGEMENT OBJECTIVES
Any proposed developments in the study area may have an impact on the natural storm water
drainage patterns of the study area. Impacts of developments may include an increase in
hardened areas, reduced infiltration areas, loss of vegetation and reduced evapo-transpiration
potential. There may also be an overall increase in the speed of runoff and peak flow rates in
the receiving streams and rivers in and around the study area.
It is thus important that storm water management system(s) form part of the study area’s
development planning process in order to reduce and manage impacts on the water cycle
during and after development. Storm water management system(s) should be planned and
designed in line with municipal storm water management policies and or engineering best
practices. The study area’s storm water management objectives should seek to address the
following objectives:
Control the quality and quantity of storm water runoff;
To protect local and downstream water courses;
Encourage natural ground water recharge;
17 | P a g e
To prevent soil erosion;
To protect all property and life from damage caused by storm water and flooding.
5.5.4. STORM WATER MANAGEMENT CONTROL MEASURES
The following design and construction measures should be adopted as control and mitigation
strategies to address the above-mentioned objectives:
Storm water runoff patterns should be assessed to determine peak flow rates and 1:100 flood
line boundaries of water courses within close proximity of the study area. Outputs from such
assessments will be used as input data required in the detailed design of culverts, channels
and other storm water infrastructure;
Storm water reticulation design and construction of storm water infrastructure should ensure
that overall development of the study area does not increase the rate of storm water flow
above that which the natural ground can safely accommodate at any point in the sub-
catchments;
Sub-surface disposal of storm water should be avoided;
All natural and unlined channels should be inspected for adequate binding of soil to reduce
erosion;
Steeper watercourses (especially in portion 206 IP) should be protected from erosion through
the use of appropriate channel linings or controlled drops to dissipate flow energy. Stone
pitching should also be used to reinforce channel inverts on such slopes;
Landscaping and or re-vegetation of areas not occupied by buildings or paving should be
constructed immediately after building works have been completed, or have reached a stage
where newly established ground cover to all sub-structures is not at risk from the construction
works.
The above-mentioned control measures will go a long way in ensuring the environmental
sustainability of the development whilst also protecting life and property from storm water
damage.

5.5.5. GEOLOGICAL OVERVIEW
According to 1:25 000 geological maps supplied by the Council for Geoscience, the study area
is dominantly underlain by amygdaloidal andesite igneous rock types of the Ventersdorp Super
Group.
A near surface geotechnical investigation is currently being conducted on the study area by
ZwaMavu Consultants to evaluate engineering characteristics of soils underlying the study
area. A detailed geotechnical investigation report will be available after the investigation has
been concluded.
5.6. BULK ENGINEERING SERVICES
5.6.1. Water Supply
The Ventersdorp town receives its potable water supply through river extraction of the
Skoonspruit River via a network of canals. The water is then purified at the Ventersdorp Water
Treatment plant and stored in reservoirs.
Potable water supply to the Ventersdorp town, the Tshing Township which is located north
west of the study area and the Moosa Park suburb is via the town’s bulk water reticulation
network while the surrounding farms are supplied by the towns canal network and bore holes.
Even though the study area currently does not have any water supply infrastructure
constructed in it, bulk service connections to service the study area can be made in the
adjacent Tshing Township.
Challenges associated with water supply within the JB Marks Local Municipality are aging
infrastructure, water losses and lack of maintenance. The Department of Water and Sanitation
in partnership with the then Ventersdorp Local Municipality have however recently completed
an upgrade of the Ventersdorp bulk water supply system which included a new 5.7 Mega liter
reservoir, an upgrade of the water treatment plant from 7 Mega liters a day to 14 Mega liters
a day along with a 2.4-kilometer-long raising main from the water treatment plant to the
reservoir. The upgrade has thus increased the town’s reservoir storage capacity to 10.3 Mega
liters and the water treatment plant’s capacity to 14 Mega liters a day.
19 | P a g e
5.6.2. Sanitation
Sewerage disposal in the Ventersdorp town, Tshing Township and Moosa Park suburb is
provided through a water borne sewerage reticulation network with the sewerage treated at
the Ventersdorp Waste Water Treatment Works (WWTW). Sewerage disposal in the
surrounding arms and informal settlements is provided through a combination of septic tanks
and pit toilets.
The current sewerage volume in the system peaks at 2.7 Mega liters a day. The capacity of
WWTW is 3 Mega liters a day. Even though the study area currently does not have any
sewerage infrastructure constructed in it, bulk service connections to service the study area
can be made in the adjacent Tshing Township.
Risks posed to the waterborne sewerage reticulation system in Ventersdorp are the aging
infrastructure along with the lack of funding to adequately maintain and or upgrade the
system.
5.6.3. Electrical Supply
Eskom is the sole bulk electricity supplier to the JB Marks Local Municipality. Residents in the
Ventersdorp town receive power from the municipality while residents in the surrounding
farms and villages are supplied by Eskom.
The current electrical supply to the municipality from Eskom is a total of 20MVA via a network
of high voltage lines. The current municipal load on the grid is 9MVA leaving 11MVA available
to service future developments and to connect villages not currently connected.
There are multiple overhead electrical power lines running through portion 205 IP and along
the R30 thus electrical connections to any new developments in the study area may be made
with relative ease.
Challenges facing the efficiency of the system include illegal connections, vandalism and aging
infrastructure to list a few.

5.6.4. Road Infrastructure
The study area is easily accessible via the N14 which is the main route linking Ventersdorp
with Colingy to the west and Krugersdorp to the east; and via R30 which is the main north-
south route linking Ventersdorp and Klerksdorp. Both access roads are paved and seem to
be well maintained.
Typical traffic on both access roads includes small vehicles for personal use, busses and trucks
transporting agricultural products between towns.
A traffic impact study is currently being conducted by MDP to assess traffic impact the
proposed development will have on the existing infrastructure and propose suitable access
points from the N14 and R30 respectively. A detailed traffic impact study report will be
available once the study has been concluded.

5.6.5. Waste Disposal
The JB Marks Local Municipality provides waste collection services to the Ventersdorp town,
Tshing Township and Moosa Suburb serviced currently by one landfill site. Waste collection
services do not extend to residents the surrounding farms, villages and informal settlements.
Some residents in these un-serviced areas currently dispose of their waste in unoccupied
parcels of land which may pose health hazards.
The close proximity of the study area to the Tshing Township will thus enable waste collection
services to easily be extended to service the proposed development.
5.6.6. OVERALL STATUS QUO ASSESSMENT
The availability of key bulk service infrastructure (bulk water, sanitation, electricity and waste
disposal) within the vicinity of the study area and the lack of any visible geological features
that may negatively affect the overall development render the study area feasible for
development.
