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.
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.
Provide a description of the alternatives considered
No. Alternative Description type, either alternative: site on property, properties, activity, design, technology, operational or other(provide details of “other”) 1 Proposal – After thorough research of the prevailing market conditions in the Capital Park area and considering Medium density the comments received to date from interested and affected parties, the developers and property Residential owners identified the need for a lower density, more upmarket, but still affordable residential development scheme. including related uses The township will be phased in to township extensions. Each township will consist of three erven, to be zoned as “Residential 3”, “private open space” and “public open space”
The applicant wishes to development a medium density residential development a maximum of 600 dwelling units to be zoned as “Residential 3” the township layout plan makes provision for two erven zoned “Public Open Space” and two erven zoned “Private Open Space” in order to ensure that each phased township/residential scheme will have direct access to the required open space areas.
The proposed land uses are thus as follows:

Total 7 +/-8.0998 600 units 38 504m² - - ha GFA
The site is approximately 8,0998ha hectares in extent.
The application site is strategically situated north of the Pretoria CBD and is easily accessible and connected to prominent public amenities, business nodes, main routes and public transport facilities.
2 Alternative 1 – The purpose of the application is to establish a High-density residential township zoned “Residential High density 3” with a maximum of 1200 units, one erf zoned “Private Open Space”, one erf zoned “Municipal” Residential and for the widening of Behrens Street in terms of the Tshwane Town-planning Scheme, 2008 development (Revised 2014). including related infrastructure The land uses in terms of Alternative 1 are as follows:
Table 2: Proposed land uses in terms of alternative 1: Proposed No of Area (ha) Density: FSR: Height: Coverage: Zoning Erven: Residential 1 +/- A 0.65 5 Storeys 40% 3 6.0496ha maximum (18m) of 1200 units Private 1 +/- - - - - open 1.8959ha space Municipal 1 +/- - - - - 0.0671ha Street - +/-0.0872 - - - - (widening ha of Behrens Street) Total 3 +/- 1200 39 322m² - - 8.0998ha units
The site is approximately 8,0998ha hectares in extent.
However the development with 1200 residential units were determined unsuitable during the public participation process that the surrounding residents and Interested and Affected Parties were not in agreement with a density of 1200 units on the site and requested that the density be reduced.
The I&AP’s issues with a density of 1200 units included: The increase in traffic caused by 1200 units Additional pressure on existing services infrastructure and provision
3. Alternative 2 – The introduction of a light industrial development, which will include warehouses, storage facilities, Light industrial workshops, etc. only, although suited to the general functioning and land uses of the surrounding development urban environment and other light industrial areas situated to the west of the site, light industrial uses are considered unsuitable due to the following reasons: Over-saturation of a single-use activity Increase of heavy vehicles on the surrounding road network, causing further damage to existing roads in the area. The housing shortage in the City of Tshwane, especially for students will not be addressed as no additional housing facilities will be provided. Inappropriateness to the adjacent residential activities situated to the north and east of the proposed site and therefore does not respond to the immediate context and surrounding land- uses Lack of diversity and vibrancy associated with a residential development and related uses Higher risk of pollution to the surrounding drainage lines and the wetland system. 4. Alternative 3 – No go No go This implies that the site be left as is and that no development or alteration be done. If this Alternative alternative is pursued the sites existing habitat will be retained. This option has the following drawbacks: The potential to provide much needed additional housing, will be lost; A very viable opportunity to create jobs and income for the local market during the construction and operational phase will be negated; The area will fall further in disrepair and the protection and appropriate management of the ecological significant areas will be negated; or Illegal squatters or vagrants may inhabit the site, having a negative impact on security and ecological resources in the area, due to washing of cloths in the watercourse situated to the west of the site and adding to the amount of waste that is currently illegally being dumped on the site. . Given the fact that the site will eventually degenerate if left unmanaged, and the fact that it is most likely unsuitable to be utilised for grazing or agricultural purposes due to its location within an urban 7 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
area, it is reasonable to state that the no-go option is less favourable than some of the other options presented. Furthermore, should this property not be developed it would be left as an isolated and disconnected land due to all the surrounding areas. The proposed project entails the construction of medium to high density residential development including related uses. See the description of the proposal above.
The development will consist of the following components:
Road Access & Traffic – Note the traffic Impact Assessment attached hereto under Annexure I4 was carried out in respect of 1200 units, however the proposal is for 300 units, therefore also refer to the addendum to the Traffic Impact Assessment attached hereto under Annexure I5. The proposed development will be served by the following accesses Behrens Street and Van Heerden Street and Behrens Street and Trouw Street
The traffic report that was completed by WSP SA Civil and Structural Engineers Division, in January 2015, in respect of the proposed development of 1200 units, (which has subsequently been reduced to 600 units) concluded as follows: The proposed development is expected to generate a total of 780 vehicles per hour during the weekday morning and afternoon peak hours (at 1200 units). During capacity analysis it was found that the road upgrades stated indicated in figure 2 and 3 below, as well as the drawings attached as part of Annexure I5 are sufficient. According to the TTPS 2008 a total of 1 600 parking spaces are required for the proposed development at 1200 units. However the amount of units have decreased to 600 units. The site development plan has made provision for 1214 parking spaces for 600 units It is proposed that the surfaced sidewalks be provided along the site frontage to facilitate pedestrian movement to the proposed development. It is therefore concluded and recommended that the proposed residential development can be accommodated on the Remainder of Portion 33 and Remainder of Portion 49 (A Portion of Portion 33) of the Farm Eloff Estate 320-JR to be known as Capital Park Extension 5 from a traffic engineering point of view.

8 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
Figure 3: proposed road upgrades
An agreement was reached with the City of Tshwane on the external road infrastructure upgrades required by the City of Tshwane (CoT) for the Capital Park Ext 5 development. These upgrades are shown in Figure 2 above dated 2 March 2015 (part of attached letter as initially included in the Traffic Impact Assessment.
Subsequent to the above agreement, a public participation meeting was held on 3 March 2015 in order to address concerns from the surrounding community with regards to the proposed new development. At this meeting concerns were raised about increased traffic volumes along 1st and 2nd Avenues between Trouw and Flowers Streets and its associated increased safety risks. The developer indicated that he would be prepared to implement traffic calming measures along these roads if such measures were required and approved by the City of Tshwane. During a telephonic discussion with Mr Frank Lambert of the City of Tshwane, possible traffic calming measures along these roads were discussed in principle and he indicated that the City of Tshwane may be willing to entertain such initiatives to address public concern.
However, since the public participation meeting of 3 March 2015, the developer decided to reduce the extent of the proposed development from 1200 to 600 units. Additionally, only 300 units will be built in the first phase of the development. This reduction in the extent of the proposed development would greatly reduce the possible impact on the surrounding community.
For this reason coupled with the fact that road upgrading requirements from the City of Tshwane never envisaged such traffic calming measures as a requirement for the proposed development, It has been determined that additional measures are not required or justified and should not be required from the developer.
Storm water Storm water run-off from the proposed development will as far as possible be restricted to surface drainage. The storm water from the proposed development will be discharged into the Apies River.
The following hydrological data will be used in the design of the storm water drainage system:
Table 3: Hydrological data in respect of the proposed development: Hydrological data a) Flood return period 1:5 years for storm water pipe systems 1:20 years for the combined storm water pipe and roadsystems b) Average yearly rainfall 700mm Minimum time of concentration and run-off co-efficient according to Tshwane Council requirements and design Manual c) Design method Rational method for small catchment areas.

General – Need and Desirability: The need and desirability for the proposed residential development is supported by its central locality, zoning and land-use surveys as well as the approved planning policies for the area.
The proposed township erven will be zoned “Residential 3”, in-line with the RSDF, 2013 development guidelines. The Tshwane Compaction and Densification Strategy 2005’s principles aim to guide residential development within Region 3 of the City of Tshwane (Central Western Region). The strategy proposes four key zones for densification, namely, High Density Zones, Linear Zones (i.e. Corridors and Spines), Suburban Densification Zones and Low Density Zones. The application site forms part of a Linear Zone.
The compaction and functional integration of the city are normative instructions from national level, and implies: Higher density urban development; Greater mixing of compatible land uses; and Focused concentration of high-density residential land-uses and intensification of non-residential land uses in nodes and along activity corridors.
The proposed development will strengthen the urban core of the area and discourage the phenomenon of urban sprawl. The application site is situated within a developing area where infill development and densification are taking place. The need for the development of the property at a higher residential density culminates from the fact that it is extremely difficult and costly to effectively secure large erven, which have become characteristic of South-African suburban neighbourhoods.
Higher residential densities can to a certain extent be regarded as a remedy for crime (especially house-breaks) due to the smaller areas that need private security surveillance and the presence of more residents in the area at different periods of the day.
The Municipality also identified this market trend and need for increased densities and the Tshwane Compaction and Densification Strategy was commissioned.
Valuable land and existing engineering services are therefore utilised more effectively as different residential opportunities (i.e. typologies and densities) are located in close proximity to educational facilities (Tshwane University of Technology), employment opportunities, Pretoria CBD and public transport facilities (E'skia Mphahlele Drive (DF Malan Drive and train stations).
Therefore the proposed development is a viable and sustainable proposal and inline with the existing development trends in this area.
With regard to the desirability of the proposed residential development, the inclusion of a Site Development Plan and Landscape Development Plan, as prerequisites for the approval of building plans, will enable the Municipality to ensure that a proper development will take place with due consideration of the surrounding approved land uses.
The development of an economic development by the private sector, which will generate substantial opportunities for the Municipality to generate revenue for residents to have access to a wide range of amenities and for jobs to be created both in the construction and operational phases and increase the City’s tax base.

15 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
The entire site consists of existing residential houses and transformed secondary succession grassland with a few scattered Acacia karrooo trees that no longer comprise the natural Marikana Thornveld vegetation, and have little or no conservation or biodiversity value. No threatened floral, faunal or invertebrate species or any sensitive habitats for such species were observed on the site. These areas are ideally suitable for development with little to no negative impact on the natural environment (low sensitivity). The canalised section of the Apies River (medium sensitivity) should be conserved as a private open space and appropriately rehabilitated with an alien vegetation removal implemented.

Please note: The Department may request specialist input/studies depending on the nature of the land use character of the area and potential impact(s) of the proposed activity/ies. Specialist reports that look at health & air quality and noise impacts may be required for any feature above and in particular those features marked with an “A“ and with an “N” respectively.
Have specialist reports been attached YES NO If yes indicate the type of reports below Annexure G1: Geotechnical Assessment Annexure G2: Ecological Assessment Annexure G3: Wetland Assessment Annexure G4: Heritage Impact Assessment 1. Geotechnical Assessment Available geological maps indicate that the area of investigation is underlying by transported alluvial soils deposited in the Quaternary Era (Quaternary alluvium). This was confirmed during the present investigation.
Based on the fieldwork the site comprises two geological / geotechnical zones, as summarized below:
Zone C1 - Localised thin fill overlying hillwash overlying nodular ferricrete / hardpan ferricrete overlying ferruginised quaternary alluvium. Zone P - Thick fill generally containing abundant builder’s rubble, ash and solid waste.
These soil zones are based on the classification system given by the NHBRC and the GFSH-2 document (2002), refer to Figure 4 below:.
Water Table No perched water table or zones of seepage were encountered in any of the test pits excavated on the site.
Zone C1 The near surface fill materials/transported hillwash are considered to be potentially highly compressible / collapsible. These soil layers are thus unsuitable for use as founding layers, even for proposed lightly loaded structures.
An allowable bearing capacity of 250kPa could be utilised for the underlying medium dense to dense or better quaternary alluvium and/or localised hardpan ferricrete. These founding horizons are encountered at depths of between 0,7m and 2,3m (average depth 1,35m) below existing ground surface. Conventional and/or deeper than normal strip or spread 5 foundations could be utilised as suitable foundation types. Under the above load conditions total settlements of the order of 5mm to 10mm are envisaged. Differential settlements should be taken as 50% of the total settlements.
Zone P The fill across Zone P is considered to be potentially highly compressible / collapsible. This soil layer is thus unsuitable for use as a founding layer, even for proposed lightly loaded structures. Based on the above comments it is apparent that special foundation procedures would have to be adopted for the structures located within Zone P or that span the contact between Zone C1 and Zone P. in this instance suitably designed piled foundations with suspended surface beds would prove to be the optimal foundation solution. Further work such auger hole drilling would have to be undertaken to establish suitable pile types and pile founding depths.

2. Ecological (Biodiversity) Assessment
2.1 Vegetation
The vegetation of the study is a classified as belonging to the Marikana Thornveld (SVcb 6) vegetation type (Mucina & Rutherford 2006). Marikana Thornveld (SVcb 6) is regarded as an endangered vegetation type with less than 1% statutorily conserved. The vegetation is characterised by the dominance of various species including the trees Vachellia karroo, Senegalia caffra, Combretum molle, Serasia lancea, Celtis Africana, Diospyros lycioides, the grasses Themeda triandra, Setaria sphacelata, Heteropogon contortus, Melinis nerviglumis, and the forbs Hermannia depressa, Barleria macrostegia, Ipomoea oblongata and Sanseveria aethiopica.
The study area is however, degraded and transformed with no vegetation reminiscent of the original vegetation remaining. The area has a low ecosystem functioning and value.
The study area comprises four vegetation units namely the 1) Grassland; 2) Open woodland; 3) Developed area and 4) Canals.
2.1.1 Grassland vegetation Unit This vegetation unit comprises the largest section of the study site. The area is mostly level with a slight western slope. The soil is loamy to clayey with a few rocks covering approximately 1% of the area present. The grasses cover approximately 75% and the forbs 8% with the single woody individuals covering less than 1% of the area.
The vegetation is dominated by the grass Cynodon dactylon and the forb Conyza bonariensis. The grasses Urochloa mosambicensis, Hyparrhenia hirta and Aristida congesta subsp. barbicollis are prominent throughout this unit. The highly invasive category 1 weed Campuloclinium macrocephalum occurs in large numbers throughout the area. Other species include the grasses Bothriochloa insculpta, Melinis repens, Chloris pycnothrix and the forbs Senecio coronatus, Verbena bonariensis and Bidens pilosa.
The Grassland Vegetation Unit is maintained as open parkland and therefore regularly mowed at approximately 3-4 cm above ground level. The grasses are normally left cut and will slowly decay. Apart from the nutrients then being returned to the soil, it also smothers large sections of the vegetation creating open spaces for pioneer and weedy species. As a result the area is representative of pioneer and secondary successional grass species not representative of the natural vegetation of these grasslands. From a plant species point of view this area has a low conservation value. Of concern is the presence of the highly invasive alien weed Campuloclinium macrocephalum that occurs scattered throughout this unit.
2.1.2 Open woodland vegetation unit This occurs in the north-eastern section of the study area on loamy to clayey soil with a low rock cover estimated at less than 1%. The trees cover approximately 15%, the shrubs 1%, the grasses 60% and the forbs 15% of the area. The vegetation is characterised by the presence of large to medium-sized Vachellia karroo (Acacia karroo) trees that occur in clumps scattered throughout the area. The grassland vegetation in-between the clumps are similar to that of vegetation unit 1 with the grass Cyndodn dactylon being the dominant grass with the grassesUrochloa mosambicensis, Aristida congesta subsp. congesta and the forbs Conyza bonariensis and Schkuhria pinnata prominent.
The bush clumps are dominated by the tree Vachellia karroo, while a large number of small individuals of the category 2 invader tree Melia azedarach are also present. The herbaceous layer is mostly degraded and comprises pioneer weedy species mostly. These include the forbs tagetes minuta, Bidens pilosa, Conyza bonariensis and the grasses Urochloa mosambicensis, Cynodon dactylon and Aristida congesta subsp. barbicollis. The grass Panicum maximum is also present underneath the canopies of the trees.
The Open woodland Vegetation unit is similar to that of the grassland vegetation unit with respect to the open grassland sections. The bush clumps show evidence of human use (dumping, clearing of vegetation etc.) with the herbaceous layer degraded comprising pioneer and weedy species mostly. In some parts rubble and garden refuse have been dumped. From a plant species point of view this area has a low conservation value.
2.1.3 The developed area vegetation unit The developed area consists of two areas where humans live and are located in the central part of the study site. These areas comprise houses/buildings and small agricultural fields where various crops are planted. A few ornamental plants and mainly pioneer and weedy species are present in these areas. A rotational planting scheme is followed with some areas left fallow and only planted after two or three years again.
The Developed area vegetation unit is degraded and transformed due to human actions (building of houses, planting of crops, etc.). These areas have various footpaths transecting them. The old fields left fallow are dominated by pioneer and weedy species. This vegetation unit has from a plant ecological point of view a low conservation value.
2.1.4 The Canal vegetation unit The Apies River forms the northern boundary of the study site and is channelled. A storm water channel that occurs all along the eastern boundary of the study site also channels storm water from the adjacent neighbourhood into the river channel.
The vegetation along the channels is a mixture of pioneer weedy and more moist-loving species. These include the woody species Combretum erythrophyllum, Gymnosporia buxifolia, Celtis Africana, Vachellia karroo, together with the alien invader trees Morus alba and Melia azedarach. Other species include the grasses Panicum maximum, Cynodon dactylon, Phragmites australis, the alien invasive grass Pennisetum clandestinum, and the forbs Datura stramonium, Zinnia peruviana, Tagetes minuta, Mariscus congestus and Ipomoea purpurea.
19 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
The vegetation of the Canal area vegetation unit is found along streams in the province and is highly degraded due to human influences. A large number of alien invasive species occur along these more moist areas from where their seeds are distributed to other places along the water course. These areas have from a plant ecological point of view a low conservation value. However, the concrete channels direct water into the river system and are therefore not suitable for development. The area is thus regarded as having a medium conservation value.
2.1.5 Medicinal Plants Only two medicinal plants were found to be present in the study site. The tree Vachellia karroo is abundant throughout the grassland and savannah biomes of South Africa, while the forb Datura stramonium is a declared category 1 weed.
2.1.6 Red data plant species No red data plant species or suitable habitat was found on the study site during the surveys. Due to the degraded habitat is doubted whether such species will occur on the site.
2.1.7 Alien plant species A number of alien invasive plant species are present on the site. These species pose a risk to the natural environment not only locally but due to the presence of the Apies River, also to other pristine ecosystems further along the river system. It is therefore important that these species are removed and eradicated.
2.2 Fauna 2.2.1 Mammals No small mammal trapping was conducted. Fieldwork was augmented with previous surveys in similar habitats as well as published data. The area was initially traversed on foot to ascertain the presence of available refuges which comprised of soil, rubble and waste stockpiles. The only mammal species observed were a few scattered African Molerat burrows in the sandier sections of the site as well as a House Rat. Mammal diversity is expected to be low and mainly urban exploiters such as the introduced House Rat and House Mouse.
Several red listed mammal species have been recorded from the 2528CA QDGC including Rough Haired Golden Mole and several bat species. No bat surveys were conducted on the site. The majority of larger mammal species are likely to have been eradicated or have moved away from the area, as a result of hunting and poaching as well as habitat alteration and degradation. Common or Bush Duiker, Black-backed Jackal have however been recorded from surrounding Waterberg situated to the south. Smaller mammal species are extremely vulnerable to snares and poaching activities as well as feral cats and dogs. According to the “South African Red Data Book of Terrestrial Mammals” (Smithers 1986) and Skinner and Smithers (1990), the study area falls within the distribution ranges of 12 species which are placed into one of known threatened species (Endangered, Vulnerable and Near-Threatened). The study site comprising transformed Marikana Thornveld does not provide suitable habitat for any threatened mammal species.
2.2.2 Avifauna Due to time constraints no comprehensive bird lists could be compiled. During brief site visitations (total of 8 hrs), 26 bird species were recorded. Two hundred and forty five (245) bird species have been recorded during the SABAP2 within the 2555-2800 pentad in which the study site is situated. The majority of species recorded during field surveys are common, widespread and typical highveld species. Numbers of bird species in the area have declined mainly due to increased levels of human disturbances (quad and off-road bikes); extensive habitat transformation due to increased urban sprawl and agricultural activities; as well as severe habitat degradation of the wetlands as well as rivers (especially the Apies River). Human activity has transformed grasslands in South Africa to a point where few pristine examples exist (Low & Rebelo 1996; Barnes 1998). Factors such as agricultural intensification, increased pasture management (overgrazing), decrease in grassland management due to frequent fires and land-use alteration (urbanisation). Continuing pressure on sensitive wetland and transformation of the surrounding open Marikana Thornveld vegetation are largely responsible for the decline of the threatened avifaunal species in the area.
At a local (Capital Park) scale the transformed grasslands on the site provide limited habitat for birds in general. Destruction of the habitat provided by the study area will have an impact of negligible significance on the conservation status of threatened species within a local (Capital Park) scale and no significance within Gauteng.
2.2.3 Reptiles Comprehensive reptile species lists are impossible to determine with extensive fieldwork over a number of months or even years. Reptile lists provided are of species most likely to occur on the site for reptile fauna present on the site is presented in the ecological assessment attached hereto under Annexure G2. As a result of human presence in the area (pathways, houses) coupled with habitat destruction and disturbances (frequent fires at incorrect time of year), alterations to the original reptilian fauna are expected to have already occurred. No scattered rupicolous or rocky outcrops and indigenous Marikana Thronevld vegetation remains on the transformed site. Destruction of rocky outcrops and removal of rock will result in the destruction of vital habitat for remaining rupicolous (living on or amongst rocks) reptile species including snakes, skinks and geckos. No termite mounds were observed within the regularly maintained grasslands within the site. Four reptile species were recorded namely a Striped or Speckled Skink (Trachylepis punctatissima), Cape Skink (Trachylepis capensis), Yellow-throated Plated Lizard (Gerrhosaurus flavigularis) and a Cape Dwarf Gecko (Lygodactylus capensis). These species are widespread and urban exploiters and were observed within the residential garden. Low reptile diversity is expected from the transformed secondary succession grasslands on the site due to extensive habitat transformation and high levels of anthropogenic activities on and surrounding the site.
No snake species were recorded during the brief field survey. Indiscriminate killing of snake species is likely to have resulted in the disappearance of the larger and the more sluggish snake species within the study area. No evidence of illegal reptile collecting was observed throughout the site although it may have occurred in the past. No threatened
20 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
reptile species were recorded during this survey, but the Coppery Grass Lizard (Chaemaesaura aenea) and Striped Harlequin Snake (Homoroselaps dorsalis), which is categorised as Near-Threatened in the latest Red Data List (SARCA 2014) has been recorded from the grid square (2528 CA) within which the study area is situated. No suitable habitat remains on the site. Coppery Grass Lizard (Chaemaesaura aenea) are unusual lizards have extremely reduced limbs (often little more than spikes) and a very long tail (3-4 times longer than the SVL length). No suitable habitat occurs within the proposed site due to the transformation (established gardens) and degradation of the majority of grasslands (ploughing activities, regularly mowed, frequent fires, alien vegetation invasion).
2.2.4 Amphibians The survey was undertaken for a single day/evening during the summer months (February), only a few species of frogs were recorded. Ideally, a herpetological survey should be undertaken throughout the duration of the wet season (September-January). It is only during this period accurate frog lists can be compiled. During this survey; fieldwork was augmented with species lists compiled from personal records; data from the South African Frog Atlas Project (SAFAP) and published data, and the list provided in the ecological assessment attached hereto under Annexure G2 is therefore regarded as likely to be fairly comprehensive.
The Giant Bullfrog (Pyxicephalus adspersus) is a protected frog species whose conservation status has been revised and was included as a Red Data Species under the category ‘Lower Risk near threatened’ (Minter et al. 2004). Limited foraging potential occurs on the site due to the transformation of the entire site into an existing residential erven and regularly maintained secondary succession grasslands with a few scattered Acacia karroo. Due to frequent cutting of the remaining patches of grasslands, the natural species composition and prey availability become transformed. No large termite mounds occur on these transformed sites. The annual emergence of several thousand winged alates provides an important food source to several animal species, especially herpetofauna.
No breeding habitat occurs on the site or in the immediate surrounding area. The artificially canalised Apies River on the north-western boundary provides limited suitable breeding habitat for frogs. The steep embankments along the artificial concrete channel on the northern boundary as well as canalised section of the Apies River on the western boundary could potentially result in a pit-fall trap from remaining frog species. Extremely limited migratory habitat remains as the site has extensive barriers/walls as well as situated adjacent to the M1 and the M 8 and a railway track to the north of the site. The M1 and M8 with their high vehicular traffic can be considered a migration barrier for the majority of frog species. Several high security walls and wire (razor) fences limit the migration of several species around the entire Capital Park area.
It is therefore considered the study site contains limited suitable foraging and migratory habitat of low conservation importance, and no suitable breeding habitat for Bullfrogs.
Destruction of the habitat provided by the study area will have an impact of low significance on the conservation status of these species within a local (Capital Park) scale and a negligible significance within Gauteng.
2.3 Summary No sensitive habitat or plant and animal species were found to be present on the site. The area has a very low biodiversity and comprises mostly pioneer, weedy, and secondary successional plant species. The various declared alien invasive species present on the study site is alarming. Not only do these species affect the study area negatively, but also serves as a central point from where their seeds are dispersed into surrounding natural areas especially with the canal present from where the seeds of these species could easily be transported to other natural ecosystems further downstream.
From a plant and animal ecological point of view the area has a low conservation and biodiversity value. All alien plant species must be removed from the property. It is recommended that the indigenous trees are conserved and development planned around them as far as possible.
At a local (Capital Park) scale the study area comprises limited suitable habitat for remaining animal species. The entire site consists of existing residential houses and transformed secondary succession grassland with a few scattered Acacia Karoo trees that no longer comprise the natural Marikana Thornveld vegetation, and have little or no conservation or biodiversity value.
No threatened floral, faunal or invertebrate species or any sensitive habitats for such species were observed on the site. These areas are ideally suitable for development with little to no negative impact on the natural environment (low sensitivity).
The canalised section of the Apies River (medium sensitivity) should be conserved as a private open space and appropriately rehabilitated with an alien vegetation removal implemented. Indigenous riparian tree species should be planted in disturbed or cleared areas.
Refer to Figure 4 above.
21 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
3. Wetland / Riparian assessment The character of the surrounding area is predominantly high density urban residential and commercial in nature with industrial developments to the west. The site is maintained as an open area and mowed on a regular basis. As a result the vegetation is degraded and not representative of natural vegetation of these areas. Some areas have been ploughed for subsistence farming purposes and various alien and pioneer species were growing in the area. A concrete channel is present along the northern boundary of the study site. Storm water from the adjacent residential buildings in the east has been channelled into this concrete channel that directs the water into the Apies River in the west. The Apies River has also been channelled and flows along the western boundary of the site. Soil and building rubble was used to fill up the areas around the channels.
The study site comprises two sections that were investigated namely the storm water channel and the Apies River Channel.
3.1 Storm water channel The storm water canal occurs along the northern boundary of the study site. The canal is overgrown with vegetation in some places and is also broken in areas. It is clear that there is 17 some overflow of storm water during heavy rainfall events with moist-loving species growing adjacent to the canal. The vegetation forms dense stands of the category 1 alien invader forb Arundo donax and Phragmites australis. Woody species present alog the canal include Gymnosporia buxifolia, Vachellia karroo, Celtis africana, Melia azedarach and Pyracantha angustifolia.
No signs of soil wetness could be found adjacent to the canal. The soil is shallow and rocky in some areas with building rubble observed 20-30 cm below the soil surface. Only dark brown soil with no clay was observed. The alien invasive grass Pennisetum clandestinum has overgrown large areas along this canal.
3.1 Apies River (Channelled) The Apies River forms the western boundary of the study site. The entire river system along the boundary of the study site has been channelled into a wide open canal many years ago. The canal was designed to control flash floods and prevent any water flowing onto the adjacent land on the canal banks.
The steep concrete sides of the canal consist of pioneer and alien invasive grasses and forbs. The alien invasive grass Pennisetum setaceum grows in the cracks and crevices of the concrete canal.
The banks of the canal comprise a mixture of different plant species. In some areas the woody layer dominates and in others the forb layer. Prominent woody species include Schinus molle, Combretum erythrophyllum, Eucalyptus camaldulensis, Melia azedarach and Morus alba. The forb layer is characterised by the prominence (and sometimes dominance) of the alien invasive forbs Mirabilis jalapa, Ipomoea purpurea and the forbs Zinnia peruviana, Bidens pilosa. The grass Panicum maximum is also present in some areas underneath the tree canopies.
Due to the previous infilling of soil and building rubble along the edges of the concrete canal auger samples could only be taken up to 20cm maximum. Only red brown soil with no clay was observed. Bricks and building rubble was encountered after 20 cm. Only brown loamy to sandy soil was found to be present.
3.1 Present Ecological State The results from the PES analysis indicate both canals to be in PES class E indicating that it is seriously modified with extensive losses of the natural habitat and ecosystem functions. This can be ascribed to the canals with their concrete walls preventing any natural flow of surface and subsurface water of the adjacent system. The roads around the park also directs all water towards the canal in the north thereby preventing any natural water to flow onto the park areas. The filling of the areas around the canals with rubble and sand also permanently changed the soil structure.
3.2 Ecological Importance and Sensitivity The EIS and functions for each of the two sections of the wetland were calculated using the new draft DWA guidelines and model. Information was used form the SIBIS and VEGMAP products. A mean score between 0 and 4 is obtained, with 0 as the lowest and 4 as the highest score (0-1 = Low to very low; >1-2 = Medium to low; >2-3 = Medium-high: >3-4 = High to very high).
The study site areas have a low Ecological Importance and Sensitivity (EIS) score of 0.31. This is a value between 0 and 4, with 0 being very low and 4 very high. This was expected since the entire water system has been canalised with no ecosystem functioning (except for the channelling of water) or natural species composition left. The vegetation consists mostly of alien invasive species and the area plays no role in water retention, flood attenuation or the provision and maintenance of sensitive ecosystems.
3.1 Vegetation alteration The effect of land use activities on the vegetation was assessed using the Wetland Index of Habitat Integrity tool to provide an indication of the effect of the previous and current activities on and around the site on the natural vegetation. Although the complete tool was developed for floodplain and channeled valley bottom areas, the vegetation alteration section was used to give a broad indication of the condition of the vegetation of the whole study area investigated. The Present Ecological State (PES) score for the vegetation alteration is 32% meaning that the vegetation is seriously modified and that the loss of natural habitat, biota and basic ecosystem functions is extensive.
The large number of alien invasive species is alarming and they pose a huge risk to the surrounding environment as well as other natural ecosystems further downstream.
22 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
3.2 Discussion The study area is completely surrounded by buildings and streets and is totally cut off from any other natural system. The construction of the concrete canals that channel the Apies River and storm water from adjacent residential areas has destroyed the original ecosystem present on the site. A large portion of the western boundary of the study site most probably formed part of a wider river embankment (of the Apies River) with maybe smaller wetland pockets in some areas, as observed elsewhere along the rivers of Gauteng.
There was no wetland found to be present on the site and no sensitive habitats or other ecosystems.
From a plant ecological point of view the area has a low conservation value while it has a low ecosystem sensitivity, importance and a low ecosystem functioning.
All sections investigated for this study are seriously modified with losses of natural habitats and ecosystem functions. All three sections have Present Ecological State (PES) and Ecological Importance and Sensitivity (EIS) scores that are below that of the acceptable norms. Together with the total isolation of the study site and the surrounding development the overall environmental significance and conservation value of the study area is regarded as being low.
In terms of the Water Act (Act no 36 of 1998 – DWAF, 1998) the study site is not defined as a wetland with no sensitive vegetation present.
All alien invasive plant species should be removed and eradicated from the area to prevent any further spread to other natural ecosystems downstream of the study site. 4. Heritage

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 proposed development promotes the use and development of land that optimizes the use of existing infrastructure and resources. The development falls within the City of Tshwane Metropolitan Municipality and the promotion and facilitation of economic development is an important objective. Authorisation will facilitate the aforementioned. The locality of this property within a suburban densification node of the City of Tshwane Metropolitan Municipality, classified as a Linear Zone according to the City of Tshwane Metropolitan Municipality’s Regional Spatial Development (RSDF), located along major routes. The routes usually carry high volumes of traffic. The proposed development therefore will contribute to the re-engineering of the existing urban form, the establishment of a more compact city and also contribute to the optimization of the use of existing infrastructure such as bulk sewer lines, bulk roads and water. The proposed development will strengthen the urban core of the area and discourage the phenomenon of urban sprawl. The application site is situated within a developing area where infill development and densification are taking place. The need for the development of the property at a higher residential density culminates from the fact that it is extremely difficult and costly to effectively secure large erven, which have become characteristic of South-African suburban neighbourhoods. Higher residential densities can to a certain extent be regarded as a remedy for crime (especially house-breaks) due to the smaller areas that need private security surveillance and the presence of more residents in the area at different periods of the day. Valuable land and existing engineering services are therefore utilised more effectively as different residential opportunities (i.e. typologies and densities) are located in close proximity to educational facilities (Tshwane University of Technology), employment opportunities, Pretoria CBD and public transport facilities (E'skia Mphahlele Drive (DF Malan Drive and train stations). The development is an economic development by the private sector, which will generate substantial opportunities for the Municipality to generate revenue for residents to have access to a wide range of amenities and for jobs to be created both in the construction and operational phases and increase the City’s tax base. There is a need for additional housing in the City of Tshwane, especially housing for students. The proposed development of a residential development promotes the availability of residential and employment opportunities in close proximity to or integrated with each other, encourages the optimal use of existing resources, encourages environmental sustainability and contributes to the development of the skills and capacity of historically disadvantaged people involved in land development.
10. CULTURAL/HISTORICAL FEATURES
Please be advised that if section 38 of the National Heritage Resources Act 25 of 1999 is applicable to your proposal or alterantives, then you are requested to furnish this Department with written comment from the South African Heritage Resource Agency (SAHRA) – Attach comment in appropriate annexure
38. (1) Subject to the provisions of subsections (7), (8) and (9), any person who intends to undertake a development categorised as-
23 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
(a) the construction of a road, wall, powerline, pipeline, canal or other similar form of linear development or barrier exceeding 300m in length; (b) the construction of a bridge or similar structure exceeding 50m in length; (c) any development or other activity which will change the character of a site- (i) exceeding 5 000 m2 in extent; or (ii) involving three or more existing erven or subdivisions thereof; or (iii) involving three or more erven or divisions thereof which have been consolidated within the past five years; or (iv) the costs of which will exceed a sum set in terms of regulations by SAHRA or a provincial heritage resources authority; (d) the re-zoning of a site exceeding 10 000 m2 in extent; or (e) any other category of development provided for in regulations by SAHRA or a provincial heritage resources authority, must at the very earliest stages of initiating such a development, notify the responsible heritage resources authority and furnish it with details regarding the location, nature and extent of the proposed development.
Are there any signs of culturally (aesthetic, social, spiritual, environmental) or historically YES NO significant elements, as defined in section 2 of the National Heritage Resources Act, 1999, (Act No. 25 of 1999), including archaeological or palaeontological sites, on or close (within 20m) to the site? If YES, explain:
If uncertain, the Department may request that specialist input be provided to establish whether there is such a feature(s) present on or close to the site.
Briefly explain the findings of the specialist if one was already appointed: The cultural landscape qualities of the region is made up of a pre-colonial element consisting of limited Stone Age and Iron Age occupation, as well as a much later colonial (farmer) component, which gave rise to an urban component.
From the 1929 Pretoria City Map (Pfaff 1929) as well as the 1939 version of the 1:50 000 topocadastral map it can be seen that very little development existed in the region of the study area. The implication is that no structures older than 60 years exist on the property.
From the aerial photograph and the site visit, it was determined that the whole area has been subjected to agricultural activities. This would have destroyed any sites, or features of cultural heritage significance that might have occurred here in the past.
As no site, features or objects of cultural significance are known to exist in the study area, there would be no impact as a result of the proposed development.
Therefore, from a heritage point of view it is recommended that the proposed development can continue. We recommend that if archaeological sites or graves are exposed during construction work, it should immediately be reported to a heritage consultant so that an investigation and evaluation of the finds can be made.
Will any building or structure older than 60 years be affected in any way? YES NO Is it necessary to apply for a permit in terms of the National Heritage Resources Act, 1999 YES NO (Act 25 of 1999)? If yes, please attached the comments from SAHRA in the appropriate Annexure

2. IMPACTS THAT MAY RESULT FROM THE CONSTRUCTION AND OPERATIONAL PHASE
Briefly describe the methodology utilised in the rating of significance of impacts 2.1 A combination of the following methods was used to identify impacts during the Basic Assessment:
2.1.1 Specialist Study Findings A minimum of legally responsible specialist studies is conducted (as usually required by the relevant authority). These usually include a red data fauna & flora assessment and heritage impact assessment. The findings of such specialist studies will highlight potential impacts on protected or endangered species or environments.
2.1.2 Site Inspection The environmental consultant and specialists conduct a site visit and identify potential sensitive environments such as streams, wetlands, and ridges. These areas are then red-flagged to be investigated further and excluded from development.
2.1.3 Public Participation Conducting public participation will produce an issues list. Such a list needs to be screened for relevant impacts, which then need to be addressed, by specialist studies or further investigation.
2.1.4 GDARD Review / Terms of Reference GDARD reviews the application and the different sub-directorates within the department give comments to the relevant environmental officer. The issues identified are forwarded to the environmental consultant and these issues are addressed or translated as impacts.
2.1.5 Methodology to determine significance of impacts The significance of the identified impacts will be determined using the approach outlined below. This incorporates two aspects or assessing the potential significance of impacts (terminology from the Department of Environmental Affairs and Tourism Guideline document on EIA Regulations, April 1998), namely occurrence and severity, which are further sub-divided as follows:
31 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
Table 4: Methodology to Assess Impacts Occurrence Severity Probability of occurrence Duration of occurrence Magnitude (severity) of Scale / extent of impact impact
To assess each of these factors for each impact, the following four ranking scales are used: Probability Duration 5 – Definite/don’t know 5 – Permanent 4 – Highly probable 4 – Long-term 3 – Medium probability 3 –Medium-term (8-15 years) 2 – Low probability 2 – Short-term (0-7 years) (impact ceases after the operational life of the activity) 1 – Improbable 1 – Immediate 0 – None Scale Magnitude 5 – International 10 – Very high/don’t know 4 – National 8 – High 3 – Regional 6 – Moderate 2 – Local 4 – Low 1 – Site only 2 – Minor 0 – None
Once these factors are ranked for each impact, the significance of the two aspects, occurrence and severity, is assessed using the following formula: SP (significance points) = (probability + duration + scale) x magnitude The maximum value is 150 significance points (SP). The impact significance will then be rated as follows: SP >75 Indicates high An impact which could influence the decision about whether or not to proceed environmental with the project regardless of any possible mitigation. significance SP 30 – 75 Indicates moderate An impact or benefit which is sufficiently important to require management and environmental which could have an influence on the decision unless it is mitigated. significance
SP <30 Indicates low Impacts with little real effect and which should not have an influence on or environmental require modification of the project design. significance
Briefly describe and compare the potential impacts (as appropriate), significance rating of impacts, proposed mitigation and significance rating of impacts after mitigation that are likely to occur as a result of the construction phase for the various alternatives of the proposed development. This must include an assessment of the significance of all impacts.

The impacts for Alternative are similar to that of the preferred alternative with the following exceptions. Traffic will increase doubly and due to double the amount of people residing in the area there will be increased pressure on existing services. Furthermore only private open space will be provided which is smaller than the proposed private and public open space proposed in the preferred alternative. Due to a larger portion of the site being developed there will be an increased impermeable surface for storm water to be absorbed into the soil.

3. IMPACTS THAT MAY RESULT FROM THE DECOMISSIONING AND CLOSURE PHASE
Briefly describe and compare the potential impacts (as appropriate), significance rating of impacts, proposed mitigation and significance rating of impacts after mitigation that are likely to occur as a result of the decommissioning and closure phase for the various alternatives of the proposed development. This must include an assessment of the significance of all impacts.
Preferred Alternative (Proposal)
Decommissioning and closure phase
The residential development and related infrastructure will probably operate in one form or another for a very long time – it is thus not realistic to evaluate the decommissioning phase at this stage. It is not foreseen that the proposed development would reach a decommissioning and closure phase due to the type of development, but should it take place the impacts area described below:
Direct impacts: The direct impacts associated with the decommissioning of the site are likely to be similar to the construction phase. Dust pollution Noise pollution Visual impact Fires and explosions may occur. Deep excavations.
Indirect impacts: The indirect impacts associated with the decommissioning of the site are likely to be similar to the construction phase. Construction traffic Security Spread of alien vegetation
Socio Economic The decommissioning of the site will result in a loss of revenue for the local economy and the loss of jobs at the site. In the short term the decommissioning phase will create jobs.
Cumulative impacts: The cumulative impacts associated with the decommissioning of the site are likely to be similar to the construction phase. Surface water pollution Increased run off of water Ground water pollution Socio Economic losses
Faunal Displacement The displacement of fauna as a result of an increase in ambient noises, vibrations is likely to remain even with mitigation. However if the site is returned to a state as close to the natural vegetation type of the area there is a possibility that fauna may migrate back over time.
Mitigation The site will only be decommissioned if it is no longer needed. Decommissioning should take place during the dry winter months. Dismantling of equipment must be conducted by an accredited contractor. Deep excavations must be cordoned off prior to being back filled. Certificates must be obtained for all actions performed. Once the site has been filled it must be rehabilitated

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: Preferred Alternative (Proposal - Medium density Residential development including related uses - (Cumulative impacts) Due to the existing disturbed and developed areas and the full regard for the environment, the cumulative impacts of the proposal would be minimal.
The proposed development will occur within the existing developed and degraded areas and no additional cumulative impacts are expected.
The ecological statement regarded the development area as having a low conservation value and ecosystem functioning.
The canalized Apies River, which was determined to have a low sensitivity, will be zoned as private and public open space and will be fenced off during construction to avoid any impact.
No sensitive fauna and flora communities were found on site, however fauna can move to the areas that will be zoned as public and private open space.
Mitigation measures as per the Environmental Management Plan, attached hereto under Annexure H, must be implemented.
Alternative 1 (High density residential development and related infrastructure) - (Cumulative impacts) Due to the existing disturbed areas and the full regard for the environment, the cumulative impacts of alternative 1 would be minimal.
However at 1200 units compared to the 600 units per hectare of the proposed alternative would allow an increased amount of people in the area. This could place slightly more pressure on the surrounding environment and natural resources in the area.
The ecological statement regarded the area as having a low conservation value and ecosystem functioning.
No Sensitive fauna and flora communities were found during the ecological assessment, existing fauna and flora species on site would be protected by implementing mitigation measures stated in the EMP
Alternative 2 (Light Industrial development and related infrastructure) - (Cumulative impacts) Due to the existing disturbed areas and the full regard for the environment, the cumulative impacts of alternative 1 would be minimal.
However light industrial activities could lead to an increased amount of heavy vehicles on the road, causing damage and adding traffic to the existing road network. Furthermore a light industrial development could add to the amount of noxious gasses in the area. This could place slightly more pressure on the surrounding environment and natural resources in the area.
The ecological statement regarded the area as having a low conservation value and ecosystem functioning.
No Sensitive fauna and flora communities were found during the ecological assessment, existing fauna and flora species on
56 BASIC ASSESSMENT REPORT [REGULATION 22(1)] site would be protected by implementing mitigation measures stated in the EMP
Alternative 3 (No go option) - (Cumulative impacts) No additional development activities will occur on site.
However no additional mitigation and rehabilitation measures will be implemented and the site could eventually degenerate, and could be subject to illegal dumping, illegal occupation of the site which could lead to veld fires, increased crime, etc.
Cumulative impacts: Surface Water Pollution Spillages of oil, lubricants and fuel from construction vehicles, plant and machinery has the potential to contaminate surface water bodies.
Increased run off of Water Stormwater run-off has the potential to erode the topsoil and result in sedimentation of water bodies if not controlled.
Ground Water Pollution The construction phase could result in increased infiltration of contaminants into the ground water and soil. The clearing of the site could result in exposed soil surfaces which may be prone to erosion, creation of dust and sedimentation of water bodies. Spillages of oil, lubricants and fuel from construction vehicles, plant and machinery has the potential to contaminate the soil and groundwater. Cement mixing and the storage of fuel must be conducted so as to prevent contamination of the soil and groundwater.
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: Medium density Residential development (600 units) including related uses All measures must be implemented to develop those areas with the least ecological value. The proposed development could also positively impact on the safety and security of the area, the expansion of services capacity (water and sanitation), as well as the upgrade of existing infrastructure.
The development will provide additional work opportunities, during the construction and operational phase, and will contribute to skills development of staff.
It is therefore suggested that the Preferred Alternative be approved.
The duration of the impacts will be during the construction phase and due to the disturbed nature of the proposed development site the Impacts from the proposed the development will be low.
The western section of the site will be allocated as private and public open space, and even though it is not sensitive, will be fenced off during the construction phase and no entry by construction staff will be allowed. Mitigation measures as per the Environmental Management Plan (EMP) attached hereto under Annexure H will be implemented.
Impacts can be successfully mitigated.
Alternative 1 – High density development (1200 units) including related infrastructure All measures will be implemented to develop those areas with the least ecological value. The proposed development could also positively impact on the safety and security of the area, the expansion of services capacity (water and sanitation), as well as the upgrade of existing infrastructure.
The development of the will provide additional work opportunities during the construction phase. A few work opportunities will be created during the operation phase in terms of maintenance jobs, piece jobs, etc. However a smaller amount of vacancies will be created as part of the high density residential development during the operation phase than is anticipated for the preferred alternative. Furthermore the amount of skills development for workers will not be as extensive.
As discussed above in the report, at 1200 units compared to the 600 units per hectare of the proposed alternative would allow an increased amount of people in the area. This could place slightly more pressure on the surrounding environment and natural resources in the area.
The duration of the impacts will only be during the construction phase and due to the disturbed nature of the proposed development site the Impacts from the proposed the development will be low.
The section of the site will be allocated as private and public open space, and even though it is not sensitive, will be fenced off during the construction phase and no entry by construction staff will be allowed. Mitigation measures as per the Environmental Management Plan (EMP) attached hereto under Annexure H will be implemented.
Impacts can be successfully mitigated, however Alternative 1, high density development (1200 units) including related infrastructure is less favourable than the proposed development and will have slightly more environmental impacts than the
57 BASIC ASSESSMENT REPORT [REGULATION 22(1)] preferred alternative. Alternative 2 – Light Industrial development including related infrastructure All measures will be implemented to develop those areas with the least ecological value. The proposed development could also positively impact on the safety and security of the area, the expansion of services capacity (water and sanitation), as well as the upgrade of existing infrastructure.
The development of the will provide additional work opportunities during the construction phase. A few work opportunities will be created during the operation phase in terms of maintenance jobs, piece jobs, etc. However a smaller amount of vacancies will be created as part of the high density residential development during the operation phase than is anticipated for the preferred alternative. Furthermore the amount of skills development for workers will not be as extensive.
As discussed above in the report, light industrial activities could lead to an increased amount of heavy vehicles on the road, causing damage and adding traffic to the existing road network. Furthermore a light industrial development could add to the amount of noxious gasses in the area. This could place slightly more pressure on the surrounding environment and natural resources in the area
The duration of the impacts will only be during the construction phase and due to the disturbed nature of the proposed development site the Impacts from the proposed the development will be low.
The section of the site will be allocated as private and public open space, and even though it is not sensitive, will be fenced off during the construction phase and no entry by construction staff will be allowed. Mitigation measures as per the Environmental Management Plan (EMP) attached hereto under Annexure H will be implemented.
Impacts can be successfully mitigated, however Alternative , light industrial development including related infrastructure is less favourable than the proposed development and will have slightly more environmental impacts than the preferred alternative.
Alternative 3 – No go option (Compulsory) This implies that the site be left as is and that no development or alteration be done. If this alternative is pursued the remainder of the site’s existing habitat will be retained. This option has the following drawbacks: The potential to provide additional retirement facilities and the thinking of the local municipality to the population, will be lost; A very viable opportunity for creating jobs (for example maintenance and construction, retirement centre staff, etc.) and income for the local market will be negated; The remaining undeveloped area will fall further in disrepair and the protection and appropriate management of the ecological significant areas will be negated; Given the fact that the site will eventually degenerate further if left unmanaged, it is reasonable to state that the no-go option is less favourable than the proposal.
The approval will ensure that an EMP be implemented and that the sensitive areas on the site will be managed and that any floral and faunal species which could be hunted illegally be moved to natural habitat and be protected.
6. IMPACT SUMMARY OF THE PROPOSAL OR PREFERRED ALTERNATIVE
For proposal: Minimal negative environmental impacts are expected and mitigation is achieved by a strict Environmental Management Plan controls any unnecessary environmental abuse.
The Apies River and associated flood lines must be protected.
The positive impacts of the proposed development include job creation during the construction and operation phase, skills development for the community, improved tax base for the City of Tshwane, provision of needed retirement facilities in the area.
For alternative: Minimal negative environmental impacts are expected and mitigation is achieved by a strict Environmental Management Plan controls any unnecessary environmental abuse.
The positive impacts of the proposed development include job creation during the construction and operation phase, skills development for the community, improved tax base for the City of Tshwane, provision of housing in the area.
However the construction of a high density residential development may have a negative impact on traffic, which will increase. Whereas the construction of the preferred alternative of a retirement centre will have a negligible impact on traffic as discussed in the report.
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 proposed development area of the site is already disturbed and the area is therefore regarded as having a low conservation value and ecosystem functioning. Therefore the development will not lead to additional impacts on the environment. Ample public and private open space is provided as part of the proposed development. The development of the residential development will optimally utilize the land to promote an accessible development, using an urban design framework which responds to the City’s requirements.
58 BASIC ASSESSMENT REPORT [REGULATION 22(1)]
The positioning of the services has been strategically planned according to the proposed layout to prevent further impacts on the ridge environment Effective storm water management can be implemented Impact on the ecological environment will be mitigated due to the implementation of the EMP during construction. The community will benefit due to various job and skills development opportunities. The city of Tshwane will benefit due to an increased tax base
7. RECOMMENDATION OF PRACTITIONER
Is the information contained in this report and the documentation attached hereto sufficient to YES NO make a decision in respect of the activity applied for (in the view of the Environmental Assessment Practitioner).
If “NO”, indicate the aspects that require further assessment before a decision can be made (list the aspects that require further assessment):
If “YES”, please list any recommended conditions, including mitigation measures that should be considered for inclusion in any authorisation that may be granted by the competent authority in respect of the application: Erosion: In order to prevent erosion towards the canalized drainage and surrounding open space areas during the construction phase, physical protection measures will be required, as well as mechanisms for dissipating water energy. Revegetation of the disturbed areas should occur as soon as possible after construction. Storm water control: The stormwater management plan for this development should include the management of surface runoff during both the construction and operational phases. The stormwater from the development should not be concentrated into the canalized section of the Apies River to the West of the site. Adequate energy dissipaters should be implemented. The stormwater should be dispersed and slowed down outside the canalized section of the Apies River, to limit erosion of the areas adjacent to the Apies River Special care should be taken to prevent sediment rich stormwater from entering the drainage line swamping the riparian vegetation with soil and lowering the water quality. The stormwater management plan is to be approved by the Environmental Division of City of Tshwane Metropolitan Municipality before construction may commence. Permeable Paving could be used to reduce runoff and increase infiltration and ground water recharge As much water as possible should be retained on site to be reused again for irrigation and habitat creation. Invasive species: All invasive species should be removed, as stipulated by CARA, and an on-going monitoring programme is required. Removal of these species should take place in an environmentally friendly way and should limit the disturbance from the removal of the species to as small an area as possible. Rehabilitation: The areas disturbed by the development, but not covered by the development, especially the areas to be zoned as public and private open space, should be rehabilitated as soon as possible and revegetated with indigenous species. The species should be indigenous to the specific area and the composition of the vegetation should reflect the natural vegetation The species used in rehabilitation of the proposed development should be indigenous to lessen the impact of exotic plant species on existing fauna and flora systems EMP Regulations in the EMP should be adhered to, to protect receiving landscape. An Environmental Control Officer (ECO) should be appointed to audit the EMP on a bi-weekly basis during construction phase SPECIALIST RECOMMENDATION All specialist report recommendations must be adhered to. MUNICIPALITY All requirements from the Tshwane Municipality must be adhered to.
