Description of compliance with the relevant legislation, policy or guideline:

Legislation, policy of guideline Description of compliance

National Environmental

Management Act No. 107 of

1998 (NEMA)

The National Environmental Management Act (Act No. 107 of 1998)

(NEMA) is the overarching framework for environmental legislation as

well as the Regulations for Environmental Impact Assessment. It sets out

the principles that serve as a general framework for environmental

planning, as guidelines by reference to which organs of state must

exercise their functions and guide other laws concerned with the

protection or management of the environment. The application takes

into account the environmental and socio-economic conditions in

compliance with the NEMA principles.

The National Environmental

Management: Biodiversity Act

(Act 10 of 2004)

The Act provides for the management and conservation of South

Af i a s iodi e sit ithi the f a e o k of the NEMA. A eas of high biodiversity need to be protected. Should any protected plants be found

on site, these will be managed in consultation with GDARD

The National Environmental

Management: Waste Act, 2008

(Act No. 59 of 2008

No waste management license would be required for the construction

of the proposed activity. Only a limited amount of solid construction

waste will be stored and handled on the site, before being hauled away

and dumped at the nearest registered landfill site.

The National Water Act, 1998

(Act No. 36 of 1998)

The A t p o ides fo the a age e t of “outh Af i a s ate esou es. It ai s to e su e that the ‘epu li s ate esou es a e p ote ted, used, developed, conserved and controlled. According to the Act, any

proposed water uses must be specified and registered and/or licensed.

Similarly, any modifications to drainage lines on site must be

investigated in terms of water use requirements.

The proposed development will require a water use licences, of which

an application thereof has been sent to the relevant authority.

National Environmental

Management: Air Quality Act,

2004 (Act 39 of 2004) (NEM:

AQA)

During the construction phase, dust and the generation of noise can

become a significant factor, especially to the surrounding landowners.

However, if the development is well planned and the mitigating

measures proposed in the EMPr are successfully implemented the

p oposed de elop e t s o t i utio to ai pollutio a d the generation of air pollution can become less significant

Occupational Health and Safety

Act (No 85 of 1993)

The Act provides for the health and safety of persons at work and for

the health and safety of persons in connection with the use of

machinery; the protection of persons other than persons at work,

against hazards to health and safety arising out of or in connection with

the activities of persons at work. The EMPr provides for measures to

ensure that objectives of the Act are met on this site

EIA Regulations GN 983 & 985

(Listing Notice 1 & 3)

The proposed development constitutes an activity listed under GN R.

983 and GN R. 985, therefore a Basic Assessment Report process is

being followed to obtain authorization from the GDARD.

Gauteng Provincial

Environmental Management

Framework

The aim of the EMF is to guide the protection and enhancement of

environmental assets and natural resources along with development

patterns to ensure sustainable environmental management and

development patterns within and around the Gauteng Province. The


7

Legislation, policy of guideline Description of compliance

development site is located in Zone 1 of the EMF which aims to promote

development infill, densification and concentration of urban

development within the urban development zones as defined in the

Gauteng Spatial Development Framework (GSDF). In order to establish a

more effective and efficient city region that will minimise urban sprawl

into rural areas; the proposed road expansion along with the upgrade of

the culverts is necessary. Therefore, the proposed activity will support

urban development which is fully supportive of the objectives of the

EMF.

Red List Plant Species

Guidelines

The purpose of the guidelines is to promote the conservation of Red List

Plant Species in Gauteng, which are species that face risk of extinction in

the wild. By protecting Red List Plant Species, conservation of diverse

landscapes is promoted which forms part of the overall environmental

preservation of diverse ecosystems, habitats, communities, populations,

species and genes in Gauteng.

The development will not impact on any Red listed plant species.

Gauteng Noise Control

Regulations, 1999

During the construction phase the impact of noise could be problematic,

but such impacts are generally short term. One should note that

practical mitigation measures for noise pollution are low, but certain

measures can be implemented to mitigate the severity. These measures

have been provided for in the EMPr

Regional Spatial Development

Framework (RSDF) 2010/2011-

Administrative Region A

The site falls within Sub Area 6 of Region A which consists of the Kyalami

Specialty Node, several neighbourhood nodes, high density residential

developments, agricultural holdings and farm portions. Despite some

parts of the sub area comprising low residential densities, the majority

of the sub area is developed at medium to high densities. The sub area

is connected to the rest of the region via several mobility roads and

spines, which experience severe traffic congestion. The vast majority of

the sub area falls within the Urban Development Boundary. The sub

area also has an environmentally sensitive area. The sub area further

experiences some infrastructure difficulties, especially in the

Crowthorne AH area.

The upgrade of the Allandale Road will support existing and planned

development as it will provide for the alleviation of traffic congestion in

the area.

Johannesburg Open Space

Management Framework

The JMOSS seeks to ensure inter-connected and managed network of

open spaces supporting interactions between social, economic and

ecological activities, sustaining and enhancing both ecological processes

and human settlements within the city. The open space linked to the

watercourse traversing the site will be maintained.

3. ALTERNATIVES Describe the proposal and alternatives that are considered in this application. Alternatives should include a consideration of all possible means by

which the purpose and need of the proposed activity could be accomplished. The determination of whether the site or activity (including different

processes etc.) or both is appropriate needs to be informed by the specific circumstances of the activity and its environment.

The no-go option must in all cases be included in the assessment phase as the baseline against which the impacts of the other alternatives are

assessed. Do not include the no go option into the alternative table below.


8

Note: After receipt of this report the competent authority may also request the applicant to assess additional alternatives that could possibly

accomplish the purpose and need of the proposed activity if it is clear that realistic alternatives have not been considered to a reasonable extent.

Please describe the process followed to reach (decide on) the list of alternatives below

The proposal is for the extension of existing culverts which from part of the already existing Allandale

Road, leaving no room for a locational alternatives. The design alternatives are also restricted by the fact

that the existing culverts will be lengthened to accommodate additional lanes for existing road.

Provide a description of the alternatives considered

No. Alternative type, Description

1 Proposal The proposal entails the upgrading and extension of the existing 3 culvert

bridges on Allandale Road as part of the associated infrastructure upgrade

for the Kyalami Gardens Ext 27 development on the Remainder of Portion

2 and the Remaining Extent of Portion 88 of the Farm Bothasfontein 408

JR, City of Johannesburg Metropolitan Municipality. The upgrades include

road widening of sections of the road which will necessitate the extension

of existing culverts to accommodate the expanded road.

The portion of Allandale Road (M39) to be upgraded stretches from the

intersection of Allandale Road and Pitts Avenue (north western end) to

approximately 28m before the interchange of Allendale Road and Harry

Galaun Drive (eastern end). The extension of the culverts will take place

across the freshwater resources being crossed.

In the event that no alternative(s) has/have been provided, a motivation must be included in the table

below.

This application pertains to the upgrading of the Allandale road especially where it crosses the streams.

Given that the proposal is for the extension of existing three culverts which from part of the already

existing Allandale Road, there are no locational alternatives considered.

The upgrades include road widening in sections of the road including where it crosses the existing culverts.

The culverts will be upgraded through laying of pipe and box culverts to extend them. The designs for the

culverts have been influenced by the existing infrastructure, configuration of the crossings and the extent

of road upgrade required. However, the culverts designs will:

- Limit the excavations within the stream;

- Limit obstruction of water flow within the stream;

- Accommodate the required width of the road for the envisaged traffic.

9. SOCIO-ECONOMIC CONTEXT Describe the existing social and economic characteristics of the area and the community condition as baseline information to assess the potential

social, economic and community impacts.

The proposal entails the upgrading of the existing 3 culverts on Allandale Road as part of the associated

infrastructure upgrade for the Kyalami Gardens Ext 27. The upgrades include widening of sections of

Allandale Road and associated culverts.

The study area falls within Sub Area 6 of Region A which consists of the Kyalami Speciality Node, several

neighbourhood nodes, high-density residential developments, agricultural holdings and farm portions.

Despite some parts of the sub area comprising low residential densities, the majority of the sub area is

developed at medium to high densities. The sub area is connected to the rest of the region via several

mobility roads and spines, which experience severe traffic congestion. The vast majority of the area falls

within the Urban Development Boundary.

The Allandale Road is historically known for traffic congestion as it links the N1 to the developed areas to

the west and east of the N1. With the recent development of the Mall Africa, office space in the vicinity and

residential area together with the Kyalami Node, investments in infrastructure include the road itself are

essential for efficient functioning of the urban space.

2. IMPACTS THAT MAY RESULT FROM THE CONSTRUCTION AND OPERATIONAL PHASE

Briefly describe the methodology utilised in the rating of significance of impacts

In order to establish a coherent framework within which all impacts could be objectively assessed, it was

deemed appropriate to establish a rating system, to be applied consistently to all the criteria. For such

purposes each aspect was assigned a value ranging from one (1) to four (4) depending on its definition. The

tables below provide a summary of the criteria and the rating scales used in the assessment of potential

impacts.

The beneficial and adverse impacts of the proposed development have been discussed below.

Nature: classification of whether the impact is positive or negative, direct or indirect.

Extent: spatial scale of impact and classified as:

o Site: the impacted area is the whole or significant portion of the site (1).

o Local: Within a radius of 2 km of the construction site (2).

o Regional: the impacted area extends to the immediate, surrounding and neighbouring

properties.

o National: the impact can be considered to be of national significance.

Duration: Indicates what the lifetime of the impact will be and is classified as:

o Short term: The impact will either disappear with mitigation or will be mitigated through

natural process in a span shorter than the construction phase.

o Medium term: The impact will last for the period of the construction phase, where after it will be

entirely negated.

o Long term: The impact will continue or last for the entire operational life of the development,

o but will be mitigated by direct human action or by natural processes thereafter. The only class of

impact which will be non-transitory.

o Permanent: Mitigation either by man or natural process will not occur in such a way or in such a

time span that the impact can be considered transient.

Intensity: Describes whether an impact is destructive or benign;

o Low: Impact affects the environment in such a way that natural, cultural and social functions

and processes are not affected.

o Moderate: Affected environment is altered, but natural, cultural and social functions and


21

processes continue albeit in a modified way.

o High: Natural, cultural and social functions and processes are altered to the extent that they

temporarily cease.

o Very High: Natural, cultural and social functions and processes are altered to extent that they

permanently cease.

o Probability: Describes the likelihood of an impact actually occurring:

o Improbable: Likelihood of the impact materialising is very low

o Possible: The impact may occur

o Highly Probable: Most likely that the impact will occur

o Definite: Impact will certainly occur.

Significance: Based on the above criteria the significance of issues the total number of points scored for

each impact indicates the level of significance of the impact, and is rated as:

o Low: the impacts are less important.

o Medium: the impacts are important and require attention; mitigation is required to reduce the

negative impacts.

o High: the impacts are of great importance. Mitigation is therefore crucial.

Cumulative: In relation to an activity, means the impact of an activity that in itself may not be significant

but may become significant when added to the existing and potential impacts eventuating from similar or

diverse activities or undertakings in the area.

Mitigation: Where negative impacts are identified, mitigation measures (ways of reducing impacts) have

been identified. An indication of the degree of success of the potential mitigation measures is given per

impact.

Significance Rating of classified impacts

Impact Points Description

Low 4-6 An acceptable impact for which mitigation is desirable but not essential. The impact by itself

is insufficient even in combination with other low impacts to prevent the development

being approved.

These impacts will result in either positive or negative medium to short term effects on the

social and/or natural environment.

Medium 7-9 An important impact which requires mitigation. The impact is insufficient by itself to

prevent the implementation of the project but which in conjunction with other impacts may

prevent its implementation.

These impacts will usually result in either a positive or negative medium to long-term effect

on the social and/or natural environment.

High

10 12 A serious impact, if not mitigated, may prevent the implementation of the project (if it is a

negative impact). These impacts would be considered by society as constituting a major and

usually a long-term change to the (natural &/or social) environment and result in severe

effects or beneficial effects.

Very high 13-16 A very serious impact which, if negative, may be sufficient by itself to prevent

implementation of the project. The impact may result in permanent change. Very often

these impacts are unmitigatable and usually result in very severe effects, or very beneficial

effects

- Erosion berms should be installed to prevent

gully formation and further siltation of the

freshwater resource, and all soil stockpiles

should be placed outside of the resource itself

and its associated 32m buffer zone, and

protected with a suitable geotextile.

- All excavated soil must be stripped and

vicinity of the construction site, outside of the

freshwater resources and a 30m buffer zone, for

subsequent use at a later stage (when removing

the coffer dam the contractor must backfill the

excavation with material which was originally

removed from the river bed. Further care must

be taken to minimise the amount of material

used for backfill which have abrasive surfaces).

- Stockpiles must be protected from the wind and

rain with the use of tarpaulins, where necessary;

- It must be ensured that weeds are eradicated

from topsoil prior to spoiling;

- Litter and general waste must be removed from

the soil prior to stockpiling;

- All/any erosion and silt control mechanisms

need to be regularly maintained for the duration

of the construction phase;

- All areas disturbed within the freshwater

resources should be monitored for erosion and

incision;

- Any areas compacted as a result of construction

activities, where applicable, shall be ripped to a

period should be kept as short as possible, and if

at all feasible, construction activities should be

scheduled for the drier months/low flow season

to decrease the risk of erosion during heavy

thunderstorms;

- The following mitigation measures are

applicable to the creation of any temporary

stream diversions:

o Prior to creating any required diversions,

erosion and sediment controls such as

sandbags and protection of exposed soils

with suitable geotextiles, must be

implemented around the site, in order to

minimise the risk of sedimentation of the

downstream areas;

o The inlet and outlet of temporary stream

diversions must be stabilized using

appropriate erosion control techniques,

and the outlet of the diversion must be

monitored for erosion; and

o Following completion of the extension of

the culverts, the stream diversion must be

removed and the affected area

rehabilitated.

o Ensure that the functionality of the

permanent, seasonal and temporary zones

of the freshwater resources is maintained

through provision of measures to ensure

that soil wetting conditions are maintained

and the freshwater resource functions are

reinstated;

- Erosion control measures around the culvert

construction sites are considered crucial. Such

measures may include sandbags to stabilize

banks and side slopes, and protection of

exposed soils with suitable geotextiles such as

hessian sheeting;

- Adequate stormwater management must be

incorporated into the rehabilitation plan in

order to prevent erosion and the associated

sedimentation of the freshwater resources. In

this regard special mention is made of:

- Any area where active erosion is observed must

be immediately rehabilitated in such a way as to

ensure that the hydrology of the area is re-

instated to conditions which are as natural as

possible.

- Drift fences constructed from hessian sheets

should be installed at erodible areas to minimise

erosion. Silt traps should also be provided to

4. CUMULATIVE IMPACTS

Describe potential impacts that, on their own may not be significant, but is significant when added to the impact of other activities or existing impacts

in the environment. Substantiate response:

Cumulative impacts refer to the incremental impacts resulting from the implementation of an activity on a

common resource which are added to the impacts of other past, present or reasonably foreseeable future

activities. The potential cumulative impacts of the township both during construction and occupation by

considering the effects of the development have been considered relative to the;

- The biophysical environment; and

- Socio-economic conditions

Specific impacts will include:

- Increase in noise pollution during construction- construction only during daytime, to reduce noise

pollution and not upset residents of the area.

- Increase in water pollution as a result of construction of the culverts and general construction

activities in the area:- measures to be put in place to limit water pollution, siltation and soil

compression. Excavated materials to be stockpiled in designated areas to prevent interference with

the natural drainage or cause siltation or water pollution.

- Alteration of surface water flows during construction and operational phases and general

disturbances to the water resources as a result of alien vegetation and siltation. Storm water

management plan to be implemented and alien vegetation cleared.

- Dusty conditions may increase: -access roads to be checked and dust prevention measures

implemented.

- During the construction phase some safety and security problems (especially for the surrounding

residents) are likely to occur.

- Improvement in vehicular flow and traffic movement in the area due to additional high order road

being opened up.

The impacts can be mitigated if activities are correctly planned and measures implemented to manage

activities which could cause any negative cumulative impacts.

5. ENVIRONMENTAL IMPACT STATEMENT Taking the assessment of potential impacts into account, please provide an environmental impact statement that sums up the impact that the

proposal and its alternatives may have on the environment after the management and mitigation of impacts have been taken into account with

specific reference to types of impact, duration of impacts, likelihood of potential impacts actually occurring and the significance of impacts.

Proposal

The application is for the upgrading and extension of the existing 3 culverts bridge on Allandale Road as part

of the associated infrastructure upgrade for the Kyalami Gardens Ext 27 development on the Remainder of

Portion 2 and the Remaining Extent of Portion 88 of the Farm Bothasfontein 408 JR, City of Johannesburg

Metropolitan Municipality. The upgrades in Allandale Road include road widening in sections of road with

three existing culverts. These culverts will be extended to suit the wider new road. The development is

necessary to improve traffic circulation in the area and to allow for the development of the remaining

phases of the abovementioned township.

Since the proposed development will traverse a freshwater resource, the probability that some short term

egati e i pa ts ill o u is o side ed defi ite . Ho e e due to the development only spanning across

the channeled valley bottom wetland and a small tributary if the Jukskei which is not too wide, impact

significance prior to the implementation of mitigation measures during construction is deemed to be of


33

medium to low levels, whilst without mitigation, impact significance during the operational phase will be of

low levels. However, efficient and effective implementation of well-designed mitigation measures can

reduce impact significance during both phases to low and very levels.

The primary modifier of the watercourse in terms of geomorphology is due to the insufficient amount of

existing culverts underneath Allandale Road, creating higher velocity and concentrated flows which has

significantly eroded the downgradient system, causing stream bank, stream bed incision and sedimentation

of the downstream system. Increased sediment loads entering the system are also due to reduced

vegetation cover, and this additional sediment contributes to scouring of the wetland channel and is

exacerbated at the culvert invert. Sediment deposits north of Allandale Road have also created additional

substrate for vegetation to establish within the wetland, increasing the surface roughness of this resource.

Due to increased velocity of stormwater inputs because of the increased impermeable surfaces and loss of

vegetation in the catchment, modifiers to the geomorphology of the tributary can mainly be attributed to

stream bank and stream bed incision and erosion. Increased sediment into the system are also anticipated

due to reduced vegetation cover and impermeable surfaces, which contributes to stream bed scouring

(especially at long drops of the culverts).

The vegetation component om this wetland is dominated by reed species (Phragmites australis and Typha

capensis). The sediment substrate allowed for the invasion of a monoculture of Phragmites australis,

dominating the entire northern section of this wetland, reducing the available substrate for other

indigenous species to establish. Due to this monoculture, floral biodiversity is low, but this wetland still has

the potential to provide habitat for other faunal species. Some proliferation of alien and invasive floral

species was also evidenced at the outer edges of the wetland, and where infrastructure (road, culverts) has

been constructed. Despite alterations to the surrounding environment, Hypoxis hemerocallidea was

observed within the wetland zone. This species is considered to be declining according to the SANBI Red List

and GDARD (orange listed species), and as such is considered as a Species of Conservation Concern (SCC).

Since the applicable section of the tributary is deemed to have been significantly modified, it is deemed

unlikely that further negative impacts would have a significant impact on the ecology of this section,

although cognisance must be taken of downstream, cumulative effects of such impacts. Therefore, it is

recommended that measures be implemented to preserve and improve the ecological functioning of this

section.

It is therefore concluded that whilst the freshwater resource is deemed to be in a heavily modified

condition, primarily as a result of various historic and recent anthropogenic activities which have caused

modifications to the geomorphology, vegetation and hydrological functioning of the system, further

degradation of the resource should not be permitted. Whilst it is not feasible to completely avoid potential

impacts as a consequence of constructing the proposed linear development, the need to prevent further

degradation should not be seen as a fatal flaw, but rather as an opportunity to improve the present state of

the river system, whilst simultaneously providing key infrastructure for development associated with this

road. Moreover, the road will help manage traffic issues related to the burgeoning development of

residential and commercial estates around the area.

Throughout the report it has been demonstrated that the proposal is sound and impacts are very minimal

and can be mitigated to acceptable le els, the e s o st o g justifia le easo to ot autho ise the development.

No-go (compulsory)

The o-go alte ati e is the optio of ot upg adu g the oad. This alte ati e ould esult potentially result in opportunities for provision of services on the site not realised. Access to good


34

infrastructure services is vital in an ever expanding urban landscape in Johannesburg. The

extension of the existing culverts bridge on Allandale Road as part of the associated infrastructure

upgrade for the Kyalami Gardens Ext 27 development on the Remainder of Portion 2 and the

Remaining Extent of Portion 88 of the Farm Bothasfontein 408 JR, City of Johannesburg

Metropolitan Municipality is viable in making the development viable.

For proposal:

After mitigation, the significance of all impacts in the short-term, are rated as low. Positive impacts of

medium significance would be realised in employment opportunities as well as compliance with the spatial

plans.

No-go alternative:

The no-go option will have low impacts on the environment; it will also have pronounced negative

impacts on the social and economic environment and therefore is not preferred.

Having assessed the significance of impacts of the proposal and alternative(s), please provide an overall summary and reasons for selecting the

proposal or preferred alternative.

The summary opinion of the proposed development is provided below as follows:

Bio-Physical Environment

- The portion of the channeled valley bottom wetland to be traversed by the road is not considered to

be particularly ecologically sensitive as a result of historical and ongoing impacts (associated

primarily with rapid urban development in the catchment). Although the activity will affect a water

course, adherence to cogent, well-conceived and ecologically sensitive site development plans, and


35

the mitigation measures provided as well as general good practice mitigation will greatly reduce the

significance of perceived impacts.

- No red listed species or sensitive fauna and flora are present on site or adjoining areas.

- The significance of most of the negative construction related impacts can be mitigated to between

low and very low significance

The information contained in this DBAR and specialist studies, provides a detailed and comprehensive

description of the proposed project, baseline environment and potential environmental impacts associated

with the proposed activity. As no significant impacts that cannot be mitigated were identified, we are of the

opinion that the project should proceed, provided the necessary mitigation and management measures are

implemented.

Social-economic Environment

- The road infrastructure and the related bridge are necessary to allow for the development of the

approved Kyalami extension 27 developments to proceed.

- The road will improve the north-south linkages and traffic flow in the area.

- Some employment opportunities will be created during the construction phase.

Alignment with spatial plans

The development proposal is compatible with the RSDF and the Provincial EMF and will support integrated

development.

7. SPATIAL DEVELOPMENT TOOLS Indicate the application of any spatial development tool protocols on the proposed development and the outcome thereof.

The Present Ecological State (PES) of the watercourse and its associated riparian zone was determined

according to the WET-IHI method described by DWAF (2007) The function and service provision of the A

channelled valley bottom wetland was assessed utilising the WET-Ecoservices as described by Kotze et al.

(2009). Further, the activity is compatible with:

- City of Johannesburg Metropolitan Regional Spatial Development Framework;

- Gauteng Environmental Management Framework.

RECOMMENDATIONS

- The recommendations of the Surface Water Rehabilitation and Management Plan must be strictly


36

implemented to manage impacts.

- Monitoring and removal of alien vegetation must be undertaken continuously for three months after the

construction of the bridge has been completed and during the first growing season.

- Effective and strict erosion control throughout the construction phase is imperative. Erosion berms

should be installed to prevent gully formation and further siltation of the channeled valley bottom

wetland. Erosion controls must be regularly maintained, at minimum on a fortnightly basis, particularly if

rain is forecast or immediately following a rainfall event. Soil stockpiles should be placed outside of the

32m buffer zone, and protected with a suitable geotextile.;

- All areas where soils are exposed or destabilised need to be stabilised taking into account the following:

o As far as possible soft engineering techniques and earthworks should be used, with special mention

of resloping of banks, revegetation of banks and stabilisation using products such as hessian sheets

and socks;

o Hard engineering techniques should only be implemented in areas where engineering and hydraulic

constraints require such interventions. In particular mention is made of gabions, reno mattresses

and reinforced walls.

o Following completion of construction, reprofiling of the banks of disturbed riparian areas must take

place, and must be revegetated with indigenous gramminoid species such as Arundinella

nepalensis, Imperata cylindrica, Setaria sphacelata and Eragrostis gummiflua;

- Adequate stormwater management must be incorporated into the design in order to prevent erosion,

bank incision and streambed scouring and the associated sedimentation of the watercourse. Use of

g ee o soft e gi ee i g te h i ues su h as “ustai a le D ai age “ ste s [“uD“] is highl recommended;

9. THE NEEDS AND DESIREBILITY OF THE PROPOSED DEVELOPMENT (as per notice 792 of 2012, or the

updated version of this guideline)

In terms of securing ecologically sustainable development and proper use of natural resources, the

proposed activity is essential for efficient traffic movement and will allow for the development of the

approved Kyalami Extension 27. Although the activity affects the channeled valley bottom wetland, the

portion of the river to be traversed by the proposed linear development is not considered to be particularly

ecologically sensitive as a result of historical and ongoing impacts (associated primarily with rapid urban

development in the catchment. However, as part of the development, mitigation measures, including

implementation of a Rehabilitation Plan will be implemented.

The demand for efficient traffic movement in and around Midrand means that the roads and associated

infrastructure need to be upgraded to support this demand, therefore the proposed upgrading of culvert on

Allandale Road is crucial to fulfilling the objectives of the Regional Spatial Development Framework.
