recommendations, statements, or conclusions drawn from or based on this report must specifically refer to this report.

If such comments form part of a main report for this investigation, the report must be included in its entirety as an

appendix or separate section to the main report.

1.3. SITE SENSITIVITY VERIFICATION METHODS USED The EAP made use of the following verification methods to compile the site sensitivity report:

• a desk top analysis using (amongst others) Google Earth, Cape Farm Mapper and BGIS,

• taking into account all information as provided by the proposed developer, appointed engineers / specialists,

municipal representatives (planners / engineers / technical members).

2. SITE SENSITVITY FINDINGS OF THE ENVIRONMENTAL SITE SENSITIVITY SCREENING REPORT The table below indicates the relevant environmental sensitivities that have been identified by the Environmental

Screening Tool and associated level of each environmental sensitivity allocated to each theme. The Screening Report

was generated in 2020 as well as in 2021 the results which depict a difference only in the ratings allocated to the

Heritage and related themes have changed from medium sensitivity to low sensitivity. The change does not impact

the outcome of the SSVR as the sensitivity of heritage theme impacts have been thoroughly investigated and reported

on by the appointed Heritage consultant and by the ROD received by HWC.

SERVICES AND ASSOCIATED INFRASTRUCTURE *Refer to services map Appendix M2

ROAD NETWORK

Sturgeon Consulting was appointed to determine the expected transport related impacts of the proposed

Development. A Transport Impact Assessment (TIA) Report has been compiled and included as Appendix G3.

ACCESS

The main access to the development is proposed from Voortrekker Road (MR227). The MR277 is a proclaimed

road according to the Western Cape Government being the controlling road authority. The access will be

located approximately 300m south of the Voortrekker Road/Waterkant Street intersection. The existing farm

access located to the east of MR227 will be relocated to be positioned opposite the proposed access at

km4.62. The existing access to the Pleasant Pheasant Restaurant and Allesverloren Farm will be permanently

closed and the new proposed access point will be the only access point of the MR227. The proposed site access

(main access) will have a three-lane cross section i.e. one lane in and two lanes out. Separate right and left

turning lanes along MR227 are also proposed. The access intersection on the development access side will be

stop controlled for right turners and yield controlled for left turners.

A secondary service access will be taken off Malan Street. This access will be reserved for service and

emergency vehicles only.

No major future road network changes are foreseen in the vicinity of the proposed development. The TIA

indicates that the study intersection is all operating at acceptable levels of service with no upgrades proposed.

Figure 4: Proposed Access

INTERNAL ROAD NETWORK

The internal streets will be paved roads, 4.5m to 6.4m wide. The road cross section will consist of 80mm thick

interlocking pavers on a 25mm sand layer on a 200mm cemented subbase (C4) on a G7 subgrade layer with

a minimum CBR of 15. The in-situ subgrade material under the roads is expected to have a G9 to G7

classification. Provision will be made to import an additional G7 subgrade layer where applicable. The road will

have mountable kerbs on both sides. The vertical alignment of the roads will be designed to enable the natural

flow of stormwater from the development.

STORMWATER NETWORK

The site has a ridge down the middle from west to east and the northern boundary has a formalised channel

just outside of the site boundary. The southern boundary has a channel “sloot” running down from the mountain

that discharges into a farm irrigation dam. The overflow of this dam ends up in the Berg River located

approximately 7km downstream.

The internal stormwater network will consist of side inlet catch pits, manholes and concrete pipes with sizes

varying from 375mm diameter to 600mm diameter. Where possible, the stormwater will be discharged directly

into swales situated along the side of the road from where it will flow into the channel on the southern boundary

of the site. The stormwater will, where possible, charge into the channels via a polishing facility. The polishing



7

dams will be landscaped elements in the development. Drawings for municipal approval will be prepared in

conjunction with the landscape architect.

The landscaped areas proposed for the new residential development including the swale is 140636.45m2. The

area that will be used for the sizing of the retention pond comprises of 97544.03m2. The introduction of swale is

to provide stormwater retention before the entrance to the existing river.

The stormwater system will be designed to accommodate the post development 1:2-year recurrence interval

run-off from the properties. The retention pond will be designed to retain the stormwater for the 1:2-year period.

This objective is applicable to all hardened surfaces within the development: roof areas, road, and parking

areas.

The following attenuation measures are proposed:

Stormwater Retention Pond and swale:

A dry stormwater retention pond as well as drained swale will be designed to handle the quantity of additional

runoff generated by the development. The water depth of the pond will be 1000mm, with a 200mm layer of

38mm crushed stone base and drainage system. The pond will have 1600 agricultural drainage pipes to drain

the rock fill layer. The pond will have inlet and outlet structures to manage the critical storm event runoff. Public

safety signage and 1.8m high fencing around the retention pond for optimal safety of the residence will be

implemented.

Detention of the 1:2-year flood:

a) Duration (Tc) = 15 min

b) Point rainfall (Table 1) 1:2 year, 15min = 9.9 min

c) Run-off factor post development: 0.7

d) Run-off factor pre-development: 0.3

e) Area: 97544.03m2

f) Post development Volume (Tc=15min): Q = CIA

= 0.7 x 0.0099m x 97544.03m2

= 675.98m3

g) Pre-development Volume (Tc=15min): Q = CIA

= 0.3 x 0.0099m x 97544.03m2

= 289.70 m3

h) Retention required = 579.42 m3

A retention pond of 27m x 26m x 1m deep will be adequate to accommodate the stormwater retention

required.

WATER NETWORK, DEMAND AND CAPACITY

Potable water will be supplied from the existing municipal water network that feeds from the Voëlvlei Purification

Works via Kasteelberg Reservoirs. Riebeek West has two pressure zones. The 1.5 megalitre reservoir feeding the

low-pressure zone gets its water from the Kasteelberg reservoirs. Water is pumped from the reservoir to the two

high level reservoirs (0.75 mega litres) which feed the high-pressure zone. Phase 1 of the Allesverloren

development will connect to the low-pressure network in Church Street and the rest of the development will

connect to the high-pressure network in Malan Street. A bulk water meter will be installed at

both connection points. The internal water network will not be taken over by the Swartland Municipality but

administered by the body corporate.

The total development will have a water demand of 147.7kℓ/day (see calculation below). The water demand

for Phase 1 is calculated at 109.9kℓ/day (see calculation below). The peak demand is calculated at 11.45ℓ/s.

No external upgrades are required for this connection point. The rest of the development will connect to the

high-pressure zone in Malan Street with a water demand calculated at 37.8 ℓ/day. The peak demand is

estimated at 5.83 ℓ/s. The supply line in Malan Street will be upgraded from a 75mm Ø to a 160mm Ø pipe.

Total Development

General Residential Zone 1 (30units/ ha) = 88 units @ 600= 52.8 kℓ/day

General Residential Zone 2 (50 units/ha) = 100 units @500= 50.0 kℓ/day

General Residential Zone 3 (Flats - 50 units/ha) = 48 units @450= 21.6 kℓ/day

Business Zone 2 = 2 500m2 @ 500ℓ/100m2 = 12.5 kℓ/day

Business Zone 2 (Residential) = 12 units @ 450= 5.4 kℓ/day

Community Zone 3 (Institutional) = 36 beds @150= 5.4 kℓ/day

Total 147.79 kℓ/day

Phase 1

General Residential Zone 1 (30units/ ha) = 88 units @ 600= 15.0 kℓ/day

General Residential Zone 2 (50 units/ha) = 100 units @500= 50.0 kℓ/day

General Residential Zone 3 (Flats - 50 units/ha) = 48 units @450= 21.6 kℓ/day

Business Zone 2 = 2 500m2 @ 500ℓ/100m2 = 12.5 kℓ/day

Business Zone 2 (Residential) = 12 units @ 450= 5.4 kℓ/day

Community Zone 3 (Institutional) = 36 beds @150= 5.4 kℓ/day

Total 109.9 kℓ/day

Internal Network

Phase 1 of the development will connect to the low-pressure network in Church Street. From the above table,

the water demand for Phase 1 is calculated 109.9 kℓ/day. The peak demand is: 109,9 kℓ/day x 9 (peak factor)

= 11,45 ℓ/s. No external network upgrades are required for this connection (GLS report – excerpt included

below).

The rest of the development will connect to the high-pressure zone in Malan Street. From the above table, the

water demand is calculated at 37.8 kℓ/day. The peak demand is: 37.8kℓ/day x 13 (peak factor) = 5.83 ℓ/s. The

supply line in Malan Street will be upgraded from a 75mm Ø to a 160mm Ø HDPE PE 100 PN12.5 pipe.

The internal network will consist of 110mm diameter to 160mm diameter HDPE 100PN12.5 pipes. Each individual

erf will have a 20mm metered water connection. Fire hydrants will be placed at a maximum of 90m intervals.

The network will conform to the standards of Swartland Municipality.

Storage Capacity

The accepted guideline is that a minimum capacity equal to 48 hours of water demand be supplied. Additional

storage capacity for Phase 1 of the development is 220kℓ. According to a recent GLS report, there is sufficient

storage capacity for Phase 1. The additional storage capacity required for the rest of the development in the

high-level reservoirs is 75kℓ with no spare capacity. The high-level reservoirs will therefore be able to provide 44

hours of storage capacity instead of 48 hours. It is proposed that the bulk capital contribution for water be set

aside for creating future storage capacity for this network.

GLS REPORT – EXCERPT

Resvoirstoorkapasiteit

Die bestaande hoerliggende reservoirs het tans 48h x daaglikse waterverbruik

(GDV) stoorkapasiteit. Die vereiste volgens die meesterbeplanning is 48h x GDV en

addisionele stoorkapasiteit word dus benodig om die hoerliggende dele van die

ontwikkeling akkommodeer (ek sien dit is nag nie op die meesterplan aangedui nie,

ons sal dit nag aanpas).

Die laerliggende reservoir het wel genoegsame kapasiteit om die laerliggende deel

van die ontwikkeling te akkommodeer.

Netwerk

Daar is (‘n paar 75 mm diameter pyplyne in die hoerliggende netwerk wat ons sal

voorstel vervang moet word met ten minste 110 mm diameter pype (dit word tans

nie in die meesterplan aangetoon nie, le fyn detail).

Vir die laerliggende deel van die ontwikkeling kan net opgekoppel word op die

netwerk.

Bulk toevoer

Die bestaande bulk toevoer vanaf die Kasteelberg reservoirs na Riebeek Wes het

voldoende kapasiteit om die ontwikkeling te akkommodeer. (Die 200 mm diameter

pyp tussen die Kasteelberg reservoirs en Riebeek-Wes moet wel in die toekoms

opgradeer word).

SEWER NETWORK

A flush sewer network will be installed. The network will consist of a 160mm diameter uPVC Class 34 sewerage

pipes. The network will gravitate via the existing network to the sewer main gravitating to the recently upgraded

Riebeek Kasteel Sewerage Treatment Works. The connection point to the sewer network will be ay he

Voortrekker/Waterkant Street intersection.

Sewer Network Demand

The average daily flow: 80% x water demand

80% x 147.7 = 118.16 kℓ/day

Peak Flow using a peak factor of 2.25 and an infiltration rate of 15%

118.16 kℓ/day x 2.25 x 1.15 = 3.5 ℓ/s

GLS REPORT: Capacity Analysis: Sewer

Daar is voldoende spaarkapasiteit in die bestaande netwerk om die ontwikkeling te

akkommodeer. ‘n Nuwe rioolyn word net vanaf die ontwilkkeling tot by die

bestaande netwerk.

SOLID WASTE DISPOSAL

Swartland Municipality collects household waste on a weekly basis for the disposal at the Highlands Solid Waste

Disposal site, which is situated 10km south of Malmesbury. The waste will be collected by the Body Corporate

and taken to the refuse rooms provided adjacent the service entrance from Malan Street from where it will be

collected by the Municipality.

Restaurant and Medical waste will be disposed of by an appropriate contractor appointed by the Body

Corporate.

ELECTRICAL SUPPLY

The supply Authority for the area is ESKOM, who confirmed the availability of 500kVA on the existing network for

this development. Any additional load will require upgrading of their backbone-supply for approximately 2km.

The ring network proposed for the Allesverloren Village will cut into the existing overhead line crossing the

development and will feed in a ring the complete development. The existing overhead line will be

accommodated in the new development and re-routed underground. Cabling within the site will be 11kV

cable. In order to provide electricity to the whole development, a miniature substation needs to be installed as

a total of 972kVA is needed for the entire development. With limited capacity available (500kVA), the Electrical

Engineer proposes that the development be phased.

Each phase will be supplied with a low-voltage cable network and kiosks, housing metering and distributing

consumer cables to each dwelling and building. The business node and institutional node will be supplied with

a dedicated minisub, allowing for bulk metering.

Manholes and sleeves will be installed along all roads, to cater for fibre/Telkom communication services to each

stand, including the business facilities.

BULK EARTHWORKS AND SITE PREPARATION

The site has an average slope of 1:14 from west to east (Malan Street to the R311 (Road 227)).

Bulk earthworks will be required to create platforms for the residential units. The cut to fill operation will be done

to the engineer’s specifications. The slopes will be stabilized with a combination of low retaining walls and

vegetated earth slopes. All earthworks and site preparations to be undertaken in accordance with engineers’

specifications. Refer to technical reports in Appendix L of the BAR.

Recommended Geotechnical Specifications:

• The general soil profile comprises a thin sandy topsoil/colluvial layer over coarse transported soils over the

residual soils and completely to highly weathered bedrock of the Malmesbury Group. Alluvial wash soils

occur in and near the lower end of the drainage course on the eastern side of the site. Fill material covers

the entire width of the southern periphery of the site where a drainage trench was excavated.

• Site clearance and preparation will include but not necessarily be limited to remediating the trial pits,

removal of a 50mm organic rich topsoil and vine roots and bushes and small trees in the southern part of

the site, removal of the overhead power line and fences and the irrigation piping, and demolition of the

restaurant and its associated septic tank/soakaway and remediation of the associated septic

tank/soakaway.

• Substantial earthworks will be required to create platforms for the various structures and for roads and

parking areas.

• The surficial sandy soils, which will form the subgrade where fill is to be placed, are currently loose to medium

dense and deep ploughing in the vineyard will have loosened the soil. It is essential that these loose soils

are densified during the initial part of the earthworks contract.

• All the materials on the site are excavatable with a digger/loader or an excavator and it is recommended

that all excavation is incorporated into one excavation class for measurement and payment. However,

excavation in restricted excavation would, in places, require excavation by jackhammering or pecking

with a monteberre attachment and this could be paid as a separate item.



10

• Although the coarse soils could be used for engineered fill, over-size cobbles and boulders will be

encountered, and these must be scalped. Crushing of the coarse soils for use as G5 or G6 material for

layerworks could be considered.

• The residual soils will not provide suitable soil for engineered fill and provision should be made to use them

in non-settlement sensitive filled areas. Use of a mixture of cohesive residual soils and sandy or coarse soils

for engineered fill will not be acceptable.

• The engineering properties of the soil profile will significantly affect founding conditions and therefore

foundation layout include the loose condition of the surficial soils, the dense and very dense condition of

the coarse soils, the occurrence of the potentially loose, deep ploughed soils in the vineyard, the

consistency and activity of the residual soils, the possible occurrence of groundwater, the settlement

characteristics of the in-situ ground and the engineered fill, loose backfill in service trenches excavated too

close to the buildings and poor compaction along the edges of embankments.

• Different foundation layouts are considered appropriate for the different ground conditions that will be

encountered or created after the earthworks have been completed. These layouts comprise reinforced

strip footings where in-situ ground is exposed or is generally at shallow depth below platforms and raft

foundations where structures are founded entirely on engineered fill or partly on engineered fill and partly

on in-situ ground.

• Various issues must be addressed, and measures adopted to supplement the general foundation layouts

and these issues and measures are described in the report.

• Engineered fill derived from the soils will generally provide poor subgrade for surface beds.

EAP MOTIVATION EAP EVIDENCE

Agriculture High The agricultural sensitivity, as identified by the screening tool, is not disputed due to the past

and current land use of the property. As such an Agricultural Specialist has been appointed

to verify the site sensitivity and provide specialist input in accordance with the Protocols

applicable for the theme.

The Specialist Input will be provided with the Draft BAR.

20% Vineyard


As such the vegetation constituting the development footprint within the development site

is not expected to be an area that would generally support an important breeding site or

habitat for any fauna or avifauna species of conservation concern.

However due to the development located adjacent to an Ephemeral stream network and

Seep Wetland as well as the proposed upgrades and infrastructure proposed within the

watercourse and the regulated area of the watercourse a Freshwater Specialist was

appointed to undertake a Freshwater Impact Assessment and Risk Matrix to inform the

impact on the sensitive Aquatic features. The Specialist Input will be provided in the BAR.

HWC Comment on HWC NID, dated 19 June 2019

You are hereby notified that, since there is reason to believe that the proposed rezoning,

subdivision and consolidation to re-develop the site will impact on heritage resources, HWC

requires that a Heritage Impact Assessment (HIA) that satisfies the provisions of section 38(3)

of the NHRA be submitted.

This HIA must have specific reference to the following:

• Visual study on a cultural landscape and town scope.

• The required HIA must have an integrated set of recommendations.

HWC FINAL COMMENT, date 11 June 2020

The Committee resolved to endorse and approve the updated landscape plans (drawing

number: 497-OvP-ANV-001 rev 05, dated June 2020) in conjunction of updated SDP via

round robin email.

Refer to HWC RoD in Appendix

F of the Application.

The HIA is included in the BAR.

Should you have any further queries, please contact the official above and quote the case

number. However, should any heritage resources, including evidence of graves and human

burials, archaeological material and paleontological material be discovered during the

execution of the activities above, all works must be stopped immediately, and Heritage

Western Cape must be notified without delay. This letter does not exonerate the applicant

from obtaining any necessary approval from any other applicable statutory authority.

REVISED FINAL COMMENT, date 22 July 2020

The Committee endorsed the SDP and Landscape plan as presented as meeting the

requirements.

Civil Aviation Low The civil aviation sensitivity, as identified by the screening tool, is disputed. The development

proposal entails the development of a mixed-use lifestyle village. The development site

does not occur on any property used for civil aviation or related activities. The proposed

land uses, and applicable internal zoning must comply with the applicable building heights

and restrictions as per the Municipal Integrated Zoning Scheme. Based on the proposed

activities and land uses, it is determined that the development components as proposed

will not pose any threat to civil aviation (specifically in terms of infringement of air space)

within the area.

The site has been transformed due to historical and current agricultural land uses and

related activities. As such the vegetation constituting the development footprint within the

development site is not expected to be an area that would generally support an important

breeding site or habitat for any fauna or avifauna species of conservation concern.

Plant species located in the adjacent ephemeral stream and seep wetland which may be

impacted as a result of the proposed development is not expected to be significant - the

impacts of which have been assessed by the Freshwater Specialist as part of the FIA.

Biodiversity

Low The Sensitivity level of the environmental theme is disputed.

Refer to the site sensitivity overlay map above. The areas of the property on which the

WCBSP (2017) mapping shows intercepting with sensitive biodiversity features have been

assessed as part of the FIA and Risk Assessment Matrix undertaken by the appointed

specialist. The recommendations and mitigation measures provided in the reports as well

as recommendations and method statements form the Project Engineers (see Technical

Reports Included as Appendix L of BAR) has been included in the BAR, EMPr, and MMP to

mitigate potential negative impacts which cannot be avoided on sensitive biodiversity

areas and features.
