SECTION B: ACTIVITY INFORMATION 1. PROJECT TITLE

Describe the project title as provided on the application form for environmental authorization: KwaPata Pedestrian Bridge 2. PROJECT DESCRIPTION

Provide a detailed description of the project: The Department of Transport (Pietermaritzburg Cost Centre) propose to construct a new pedestrian bridge within the Msunduzi Local Municipality. The pedestrian bridge will comprise a deck suspended across concrete pier bases crossing the stream below. Attached to this bridge will be a low level pedestrian walkway that traverses a wet area. Pedestrians currently use an informal track to traverse the wet area that is prone to flooding and requires regular maintenance. A third structure to be built south east of the pedestrian bridge is a formal railway pedestrian bridge. Local residents currently cross the railway line on foot which is a significant safety hazard especially for young children and the elderly. These structures would therefore be a public amenity and facilitate safer and more efficient pedestrian movement within the area. Please see Appendix A for location details. Structure Details: Pedestrian River Bridge: The proposed structure is a raised concrete bridge structure. The bridge deck is approximately 20m in length and 1.2m in width with a 22m sloped approach ramp on the eastern side of the structure (Refer to General Arrangement River Bridge in Appendix C). The formal engineering description is as follows “The bridge comprises of in-situ concrete T-beam deck supported on reinforced concrete pier and abutment founded on spread footings.” There are no support piers to be placed within the river itself as the deck is supported by the abutments on either side of the river bank. The abutment foundations will be doweled into the bedrock below the structure. The western bank is higher than the eastern back and falls away sharply. It is proposed to construct reno mattresses (wire mesh rock basket) to provide scour protection around this abutment on the western bank and essentially stabilizing this area. There is no approach ramp on the western edge of the structure as the bridge connects directly to the raised pedestrian walkway. Raised Pedestrian Walkway (low-level bridge): This proposed structure connects to the pedestrian river bridge on the western edge of that structure. The proposed structure has a deck approximately 78m in length and 1m in width with a 5.2m sloped approach ramp at the end of structure. The deck will be approximately 2m above the natural ground level (this varies as the ground level is not completely flat) and will be supported by 12 piers approximately 6m apart (Refer to General Arrangement Low-Level Bridge in Appendix C). The formal engineering description is as follows “The bridge comprises a precast beam and block system with an in-situ concrete walkway slab, supported on reinforced concrete and an abutment found on CFA* piles.” This structure will serve to formalize an existing pedestrian pathway through a wetland area. The proposed structure has been chosen in order to allow for the natural hydraulic movements of water within the wetland to continue as well as prevent further degradation of the area due to local residents’ informal initiatives to maintain the path (dumping of building ruble along the path way). The structure will enable pedestrians to traverse the large wet area safely and efficiently with minimal inconvenience. Railway Bridge: On the eastern edge of the site pedestrians currently cross the railway tracks at an informal crossing point attached to the edge of the bridge with dilapidated hand rails and base to walk on. It is proposed that a formal railway bridge for pedestrian use be constructed (see appendix A for the location of the proposed bridge). The bridge deck will be approximately 22m in length and 1.5m in width with tiered stairs on either side of the structure. The bridge




Page 4 of 47

height will be approximately 3m and is designed to accommodate locomotives and carriages that travel along the railway track (Refer to General Arrangement Railway Bridge in Appendix C). The formal engineering description is as follows “The bridge comprises framed structural steel trusses supporting a concrete walkway on permanent steel shuttering supported on reinforced concrete piers and abutments founded on 300mm CFA* Piles”. The railway bridge serves to formalize the existing crossing point and give local pedestrians the opportunity to cross the railway in a safe and efficient manner, crossing the railway at the moment is a significant hazard for both the elderly and the hundreds of young children walking to the schools on the other side of the river and railway line. All structures will have appropriate side railings to ensure that pedestrians can use these facilities without significant risk of injury. The KwaPata Pedestrian Bridge is one project with three separate structures; however the combined goal of these structures is to facilitate safe and efficient pedestrian movement in this area. As such there are a number of potential social, economic and environmental impacts and for the purposes of this report these impacts will be assessed as if referring to the project in its entirety (all three structures). Where an individual structure has a unique impact, this will be explicitly referenced. If no reference is made to an individual structure the impact refers to the cumulative impact of the entire project. *CFA stands for continuous flight auger this is a type of pile commonly used in South Africa. An auger is used to create a cavity and then concrete and reinforcing are placed in this cavity.

3. ACTIVITY DESCRIPTION

Describe each listed activity in Listing Notice 1 (GNR 544, 18 June2010) or Listing Notice 3 (GNR 546, 18June 2010) which is being applied for as per the project description: The proposed location of the bridge structure is across a stream, therefore the following regulations will apply: 11. The construction of: (iii) bridges Where such construction occurs within a water course or within 32 meters of a watercourse, measures from the edge of a watercourse, excluding where such construction will occur behind the development setback line. 18. The infilling or depositing of any material of more than 5 cubic metres into, or the dredging, excavation, removal or moving of soil, sand, shells, shell grit, pebbles or rock from (i) a watercourse

4. FEASIBLE AND REASONABLE ALTERNATIVES

“alternatives”, in relation to a proposed activity, means different means of meeting the general purpose and requirements of the activity, which may include alternatives to— (a) the property on which or location where it is proposed to undertake the activity; (b) the type of activity to be undertaken; (c) the design or layout of the activity; (d) the technology to be used in the activity; (e) the operational aspects of the activity; and (f) the option of not implementing the activity. Describe alternatives that are considered in this report. Alternatives should include a consideration of all possible means by which the purpose and need of the proposed activity could be accomplished in the specific instance taking account of the interest of the applicant in the activity. The no-go alternative must in all cases be included in the assessment phase as the baseline against which the impacts of the other alternatives are assessed. The determination of whether 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. After receipt of this report the




Page 5 of 47

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. Site Alternatives The project entails the construction of a bridge across a stream, a low-level walkway to traverse a wet area and a railway bridge along a well-established pedestrian route. The proposed location of the structures is the preferred site as pupils and residents currently traverse the stream near to this point to access the adjacent schools and homes, therefore there is only one preferred site alternative. Use of the current route has a number of risks and hazards that pedestrians must negotiate. The site has been chosen on the basis that the current route is deemed to be a significant health and safety risk for local residents and therefore needs to be upgraded. Over the past years there have been several deaths due to the current state of the crossing point. Technology Alternatives Alternative 1 (Preferred Alternative) The preferred alternative is to construct three structures as described in the project description. A pedestrian bridge where the deck is approximately 20m in length and 1.2m in width with a 22m sloped approach ramp on the eastern side of the structure. A raised pedestrian walkway** that has a deck approximately 78m in length and 1m in width with a 5.2m sloped approach ramp at the end of structure. The deck will be approximately 2m above the natural ground level (this varies as the ground level is not perfectly flat) and will be supported by 12 piers approximately 6m apart. The third structure is a Railway Bridge with a deck that will be approximately 22m in length and 1.5m in width with tiered stairs on either side of the structure. The railway bridge height will be approximately 3m and is designed to accommodate locomotives and carriages that travel along the railway track. Alternative 2 The second alternative is to construct three structures with the following description. A pedestrian bridge where the deck is approximately 20m in length and 1.2m in width with a 22m sloped approach ramp on the eastern side of the structure and a 5.2m sloped ramp on the western edge of the structure. A concrete pedestrian pathway** approximately 2m wide, 30cm in height and 70m in length (not raised). The third structure is a Railway Bridge with a deck that will be approximately 22m in length and 1.5m in width with tiered stairs on either side of the structure. The railway bridge height will be approximately 3m and is designed to accommodate locomotives and carriages that travel along the railway track. No Go The proposed structures will not be constructed. Community members will continue to make use of the old railway bridge to cross the stream, this bridge is old and unsafe. The narrow deck and awkward handrails make the use of the bridge treacherous for both young students and the elderly alike. A number of individuals have already lost their lives while using the bridge either from the fall itself or drowning in the steady flow of the stream below. No construction means that a safer alternative will not be provided and pedestrians will continue to negotiate the hazards of this route on their daily commute. The wetland area will also continue to degraded. **bold denotes the difference in project description.

Sections B 5 – 15 below should be completed for each alternative.

11.2. Need and desirability of the activity

Motivate and explain the need and desirability of the activity (including demand for the activity): The proposed bridge construction was identified by local residents, working through their ward councilor, as a key project in the area. Community members currently make use of the old railway bridge to cross the stream, this bridge is however old and unsafe and pedestrians require a safer alternative. The narrow deck and awkward handrails make the use of the bridge treacherous for both young students and the elderly alike. A number of individuals have already lost their lives while using the bridge either from the fall itself or drowning in the steady flow of the stream below. Unfortunately this is their only option to access the adjacent schools and health facilities and thus a constant flow of pedestrians were observed using this crossing point during the site visit. The construction the bridge structures are needed to ensure pedestrians can traverse the river, wet area and railway track safely.

Indicate any benefits that the activity will have for society in general: The creation of the formal bridge structures will enable community members to traverse this route safely and efficiently, reducing the risk associated with using the old railway bridge. Ensuing economic benefits would include a reduction in the call outs of emergency services




Page 8 of 47

attending to accidents or incidents associated with the use of the unsafe infrastructure and additional time available especially for parents who will no longer need to escort their children to and from school. Community members will no longer have to take it upon themselves to maintain the access through the wet area and will have additional time for other productive activities. The reduced activity within the wetland area will decrease the amount of disturbance within this area and over time lead to improved functionality within the wetland.

Indicate any benefits that the activity will have for the local communities where the activity will be located: Construction of the new structures would have significant social benefit for the surrounding community and would have high public amenity value. Young pupils and the elderly would be able to access both the adjacent schools and health care facilities safely. They will be able to traverse the stream and railway line without the significant risk of injury. Additionally, the low-level walkway across the wet area will ensure that community members traverse this area without any inconvenience or further impact on water movement within the wetland. Currently, community members traverse the wet area by walking on rubble that has been placed along the path, the raised pedestrian walkway structure will prevent additional rubble being placed in this area and having further negative on the wetland area. There will also be temporary employment of local community members during the construction phase of the project

The shallow water table refers to areas immediately adjacent to the river and within the wetland area. Seasonally wet soils are located within the wetland area to be traversed by the low-level pedestrian walkway. The area sensitive to erosion refers to the steeply incised river banks of the KwaPata River which are approximately 3m in height. It is proposed to construct reno mattresses around the bridge abutment on the steep river banks to stabilise this area and prevent scour in this area. As per the findings of the geotechnical report the regional geology of the area is to comprise of Pietermaritzburg Formation Shale intruded by numerous dolerite dykes/sills overlain by recent alluvium deposits. Figure one within the geotechnical report in appendix C illustrates the inferred geology of the area based on the results of the geotechnical investigation.

If you are unsure about any of the above or if you are concerned that any of the above aspects may be an issue of concern in the application, an appropriate specialist should be appointed to assist in the completion of this section. (Information in respect of the above will often be available as part of the project information or at the planning sections of local authorities.

If any of the boxes marked with an “E “is ticked, please consult an appropriate specialist to assist in the completion of this section if the environmental assessment practitioner doesn’t have the necessary expertise. The vegetation surrounding the site is predominantly disturbed grassland with scattered alien plant species. These plants include Peanut Cassia, Lantana and Bugweed and are most prolific immediately adjacent to the KwaPata River and the Railway Track. They have essentially colonized areas that have been previously disturbed by human activity. This disturbance could be attributed to the high number of pedestrians frequenting the site or previous construction activity. Adjacent to the existing footpath through the wet area are common reed species. It should however be highlighted that the vegetation on the edge of this informal path has been disturbed as a result of frequent pedestrian traffic, the dumping of rubble material in this area as well as the steady input of litter into the area. The buildings and other structures refer to the railway track itself as well as the underground services and pipes that are in the area. The Geotechnical Report highlighted the fact that numerous services are expected to be encountered in the area as they service the schools etc. in the surrounding area. There is an informal sports field on the western edge of the KwaPata River that appears to be used by local residents. The bare soil on site refers to the existing path itself where the vegetation no longer grows due to frequent pedestrian traffic. Other exposed areas include portions of the river bank where vegetation has been removed by the flowing water or areas where residents have cleared to provide easier access through the wet area.

5. LAND USE CHARACTER OF SURROUNDING AREA

Cross the land uses and/or prominent features that currently occur within a 500m radius of the site and give a description of how this influences the application or may be impacted upon by the application: Land use character Description

Spoil heap or slimes dam YES NO

Quarry, sand or borrow pit YES NO

Dam or reservoir YES NO

Hospital/medical centre YES NO Edendale Hospital is located approximately 500m north west of the site. Construction of the bridges will facilitate safer and easier access for residents on the eastern banks of the river. This will significantly reduce the risk and hazards for residents to access health care facilities, which is especially important during emergencies or the treatment of acute medical conditions.

School/ crèche YES NO There is a school located to the west of the site. The low-level pedestrian walkway is the structure nearest to this facility. Care must be taken during construction to ensure safety of school children. Once complete the bridge will be of significant benefit to local scholars who will be able to traverse the wet area, river and railway line in a safe and efficient manner. The existing pedestrian pathway has a number of hazardous obstacles especially for young children.

Tertiary education facility YES NO

Church YES NO

Old age home YES NO

Sewage treatment plant YES NO

Train station or shunting yard YES NO

Railway line YES NO The railway bridge will be built over the existing the railway line providing pedestrians with a safer option to make use of when crossing the track. The construction process will need to be carefully managed to ensure that there is no disruption to rail traffic during the construction phase of the project.

Major road (4 lanes or more) YES NO




Page 14 of 47

Airport YES NO

Harbour YES NO

Sport facilities YES NO There appears to be an informal school sports field adjacent to western end of the proposed structure. Care must be taken during construction to ensure the safety of school children. Any negative impact upon this area must be resolved prior to the contractor leaving site.

Golf course YES NO

Polo fields YES NO

Filling station YES NO

Landfill or waste treatment site YES NO

Plantation YES NO

Agriculture YES NO Small scale subsistence farming occurs within the plots of the local homesteads. No expected impact on these activities.

River, stream or wetland YES NO The proposed bridge structures will be located within the KwaPata River and the adjacent degraded wetland area. Construction of the bridges will be carefully managed through provisions within the Environmental Management Program (EMPr) and monitored by an independent Environmental Control Officer (ECO). The river bridge is to be placed in a location and the design is such that no piers will be constructed within the riverbed itself. The bridge will be supported by abutments on either side of the river. The structure will therefore have very limited impact on the aquifauna within river as well as limited impact on the hydrodynamics of the river. Depending on the quantity of water flowing within the main river channel there may be the requirement for temporary diversions to establish the abutment spread footings. A dry surface is required for the drilling of the steel dowels into the bedrock and for the concrete foundations to set. Even if a diversion is required it is not anticipated that there would be any obstruction of water flow during the construction process. Construction of the low-level pedestrian walkway will require limited clearing of vegetation within the footprint of the proposed structure. Construction activity would create a significant impact in this section of the wetland for a short period of time but would then essentially remove potential future disturbance when residents attempt to re-establish their informal path. This




Page 15 of 47

informal maintenance activity impacts on the hydraulics of the wetland as residents dump rubble material along the path and the frequent pedestrian traffic does not allow the wetland vegetation to re-establish itself. Thus, the potential impacts during both construction and operation will essentially be restricted to the construction footprint and immediate vicinity of the structure.

Nature conservation area YES NO

Mountain, hill or ridge YES NO

Museum YES NO

Historical building YES NO

Protected Area YES NO

Graveyard YES NO

Archaeological site YES NO

Other land uses (describe) YES NO

6. CULTURAL/ HISTORICAL FEATURES

Are there any signs of culturally or historically 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 within 20m of the site?

YES NO X

If YES, contact a specialist recommended by AMAFA to conduct a heritage impact assessment. The heritage impact assessment must be attached as an appendix to this report.

Briefly explain the recommendations of the specialist:

NA

Will any building or structure older than 60 years be affected in any way? YES NO X

Is it necessary to apply for a permit in terms of the National Heritage Resources Act, 1999 (Act 25 of 1999)? The river bridge (20m) and railway bridge (22m) do not require a heritage impact assessment as they are below 50m threshold. The proposed low-level pedestrian walkway is essentially the formalization of an existing path; the area has therefore been previously disturbed by pedestrian traffic as well as limited maintenance activity in the form of the placement of rubble along the path alignment. It should also be noted that there has been the previous construction activity in terms of the installation of services to accommodate the surrounding buildings which would have involved both excavation and trenching activity. Therefore no heritage permit is required.

YES NO X

If YES, please submit the necessary application to AMAFA and attach proof thereof to this report. NA

SECTION D: PUBLIC PARTICIPATION The project is located on the periphery of the urban edge, therefore the public participation method used had to ensure that existing channels of communication were used in order to notify surrounding stakeholders so as to avoid creating any offense. Surrounding




Page 16 of 47

stakeholders rely on direct means of communication through an elected official which in this case was the Ward Councilor and his ward committee. It is important to note that any communication that takes place with community members without working through these elected officials is seen as disrespectful and to a point irrelevant as ward councilor has been elected to facilitate such communications. Meetings were held with these respective community leaders who relayed information to the community. As the structures selected for construction was identified and requested by the community, the primary purpose behind the notification was to ensure that the community was made aware of the commencement of the environmental assessment. The following steps were followed during the public participation process.

· A meeting was held with the ward councilor where the project details for the bridge under discussion were presented.

· The Ward Councillor indicated a willingness to engage with the community, agreeing that this was the best procedure for notification.

· Signboards detailing the upgrade were erected.

· The Ward Councillor was provided with pamphlets for distribution.

· The Ward Councillor and ward committee will be given an opportunity to review complete copies of the Basic Assessment report and relay information back to the community.

· With regards to authority communications, all relevant authorities have been notified of the application and have been provided with copies of this BAR.

2.3. IMPACTS THAT MAY RESULT FROM THE OPERATIONAL PHASE a. Site alternatives b. Process, technology, layout or other alternatives

SITE ALTERNATIVES The project entails the construction of a bridge across a stream, a low-level walkway to traverse a wet area and a railway bridge along a well-established pedestrian route. The proposed location of the structures is the preferred site as pupils and residents currently traverse the stream near to this point to access the adjacent schools and homes, therefore there is only one preferred site alternative. Use of the current route has a number of risks and hazards that pedestrians must negotiate. The site has been chosen on the basis that the current route is deemed to be significant health and safety risk for local residents and therefore needs to be upgraded. CONSTRUCTION PHASE

Impacts The following lists the potential impacts associated

with the construction phase and is applicable to the proposed site. Mitigations The following lists mitigation measures that

may eliminate or reduce the potential impacts listed: Direct impacts:

1. Temporary disturbance of pedestrian traffic. 2. Damage to surrounding infrastructure and

services by irresponsible contractors. 3. Generation of emissions from construction

vehicles. 4. Dusty conditions generated by construction

vehicles travelling over exposed soil. 5. Deposition of eroded material into KwaPata

River and wetland area. 6. Erosion of exposed soil (specifically existing

access paths) prior to the rehabilitation of the construction area.

7. Damage to river, river bank, wetland and riparian zone due to construction vehicles and heavy equipment moving within these

Direct impacts:

1. Pedestrians will need to find alternate routes around the construction areas during construction; however this will only be temporary. Surrounding stakeholders will be notified prior to disruptive activities during construction. The contractor must take into consideration the potential movements of surrounding stakeholders.

2. As standard construction practice the engineer and contractor will identify all existing services that may be affected prior to construction.

3. All construction vehicles will be fitted




Page 20 of 47

areas. 8. Clearing of and damage to surrounding

vegetation. 9. Temporary increase in waste and litter due

to the construction process. 10. Improper disposal of construction rubble i.e.

illegal burying or dumping of rubble around the roads preventing rehabilitation.

11. Contamination of the receiving environment due to inappropriate storage and usage of hazardous materials and substances (cement, fuel etc.)

12. Insufficient number of toilet facilities resulting in unsanitary conditions on site.

13. Inappropriate disposal of toilet waste resulting in the contamination of the environment.

14. Contaminated run off polluting the KwaPata River and Wetland area.

15. Generation of noise. 16. Speeding construction vehicles creating

unsafe working conditions. 17. Encroachment of alien vegetation into areas

disturbed during construction. Indirect impacts:

18. Unsustainable sourcing of raw materials such as gravel, sand, water etc. which could result in the promotion of illegal mining operations which can cause significant damage to the environment.

Cumulative impacts:

19. General increase of waste to landfill

with the appropriate silencers and exhausts. Emissions generated from these vehicles will be negligible and are not expected to significantly affect surrounding communities.

4. A water cart will be used to dampen dusty surfaces and suppress dust.

5. Areas exposed to erosion will be protected through the use of sand bags, berms and efficient construction processes i.e.: limiting the extent (footprint) and duration period that areas are exposed.

6. Exposed areas will be rehabilitated and re-vegetated as soon as possible during construction.

7. No ad hoc roads may be created. The contractor must mark out the minimum required construction area on the river and within the wetland area and vehicle access must be restricted to this area only. A 15m buffer should then be imposed on the rest of the river and wetland area with no traffic or vehicles or storage permitted within this buffer zone. This will reduce the area affected. Where possible, heavy vehicle access to the river and river banks must be restricted. Non-essential equipment and vehicles are to remain at least 15m from the river banks at all times. Materials may not be stored within 15m of the river bank.

8. There will be clearing of vegetation within the footprint of the proposed structures. The majority of the site besides the wetland area is disturbed grassland with scattered alien invasive vegetation. The EMPr will address vegetation and the clearing the required, should not result in loss of irreplaceable species. Clearing of vegetation for the construction of the low-level pedestrian walkway will for the most part take place along the existing informal access path.

9. There is already an existing problem with litter on site. Littering will not be permitted on site. Waste management will be controlled through the implementation of the EMPr.

10. Contractors will be required to dispose of construction rubble at an appropriate landfill site. Delivery notes and safe disposal certificates to prove appropriate disposal will be required during the construction audits conducted by an independent environmental consultant.




Page 21 of 47

11. All hazardous materials and substances will be stored within a secured area in the construction camp. No storage of material is to occur within 15m of the river. The storage area will be a hard surfaced, bunded and covered. Cement mixing must be done on a hard surface that is protected from storm water runoff.

12. Appropriate and sufficient toilet facilities will be provided by the contractor and will be controlled through the implementation of the EMPr.

13. Toilet facilities must be provided by a registered company and all sewage must be disposed of at an appropriate facility. Safe disposal certificates will be kept on record. Any spills must be immediately contained and the spilled material disposed of appropriately. Toilets may not be located within 15m of the river and wetland.

14. The engineer must ensure that only clean storm water runoff enters the surrounding environment. Any contaminated run off must be collected and disposed of.

15. All construction vehicles will be fitted with standard silencers. The noise generated will be a temporary impact during construction.

16. Speed limits must be obeyed and enforced.

17. The construction EMPr will specify that alien vegetation will not be allowed to encroach onto the site and must be continually removed.

Indirect impacts:

18. The implementation of the EMPr will manage these issues. Contractors must provide proof of sustainable sourcing of materials i.e. permits for quarries and sand winning operations from which stone and sand have been obtained.

Cumulative impacts:

19. Waste generated during the upgrade will consist of building rubble and construction materials and general litter and will only be temporarily generated during the construction period.

OPERATIONAL PHASE


with the operational phase and is applicable to the proposed site. Mitigations The following lists mitigation measures that

may eliminate or reduce the potential impacts listed: Direct impacts:

1. Debris such as trees and branches may get Direct impacts:

1. The height of the bridge and width




Page 22 of 47

caught on the river bridge abutments and reno mattresses resulting in increased flow resistance and damage to the structure.

2. Flood events overtopping the river bridge, damaging the structure and making the way impassable for pedestrians.

3. Potential erosion of the surrounding area especially at the ends of the river bridge, destabilizing it and resulting in material loss which will enter the waterway.

4. Impact on the hydraulic functioning of the wetland area.

5. Decreased amount of regular disturbance within the wetland area as a result of frequent pedestrian traffic as well as regular maintenance activity along the existing pathway.

Indirect impacts: 6. Access to the adjacent schools, hospital and

residential homesteads will be improved and maintained, having a direct positive impact on the well-being of pedestrians.

7. Potential alteration of river flow dynamics due to poor placement of the river bridge.

Cumulative impacts: 8. Improved access to the area allowing for

growth and improvement in service delivery for surrounding communities.

9. The upgrading of this existing pedestrian route significantly reduces the risk to local users of the route as the existing hazards can be safely negotiated.

(20m) between the abutments will be of sufficient size to allow water to flow unobstructed. There are no piers within the riverbed; this will allow the passage of sediment and debris to flow without becoming obstructed.

2. The engineer has completed a hydraulic assessment of the catchment area and the bridge design has taken to account the water levels at various rates of precipitation and thus should only be overtopped during extreme flood events. As such any inconvenience related to overtopping would be minimal.

3. Erosion protection features will be installed i.e. reno matresses will be installed at appropriate locations on the structure to ensure the stormwater does not erode the foundations and abutments of the new structures.

4. The proposed raised pedestrian walkway traverses the wetland area. The structure has been designed to limit its footprint and impact on the functioning of the wetland. An elevated structure will allow for a natural hydraulic flow through the wetland.

5. Construction activity would create a significant impact in this section of the wetland for a short period of time but would then essentially remove potential future disturbance when residents attempt to re-establish their informal path. This is considered to be a positive impact.

Indirect impacts:

6. This is a positive impact. 7. The engineer has completed a

hydraulic assessment of the catchment. The structure has been designed and located to ensure that the natural flow of the water course is not interrupted and there is no significant change in hydrology above or below the structure. The bridge abutments have specifically been located outside the river bed to reduce impact on the flow dynamics.

Cumulative impacts:

8. This is a positive impact. 9. This is a positive impact.

TECHNOLOGY ALTERNATIVES

Both alternatives will span the same approximate area along the existing pedestrian pathway. However, due to the differences in design they have potential to cause very different impacts during both the construction and operational phase. Alternative 1 (Preferred Alternative) The preferred alternative is to construct three structures as described in the project description. A pedestrian bridge where the deck is approximately 20m in length and 1.2m in width with a 22m sloped approach ramp on the eastern side of the structure. A raised pedestrian walkway that has a deck approximately 78m in length and 1m in width with a 5.2m sloped approach ramp at the end of structure. The deck will be approximately 2m above the natural ground level (this varies as the ground level is not perfectly flat) and will be supported by 12 piers approximately 6m apart. The third structure is a Railway Bridge with a deck that will be approximately 22m in length and 1.5m in width with tiered stairs on either side of the structure. The railway bridge height will be approximately 3m and is designed to accommodate locomotives and carriages that travel along the railway track. Alternative 2 The second alternative is to construct three structures with the following description. A pedestrian bridge where the deck is approximately 20m in length and 1.2m in width with a 22m sloped approach ramp on the eastern side of the structure and a 5.2m sloped ramp on the western edge of the structure. A concrete pedestrian pathway approximately 2m wide, 30cm in height and 70m in length. The third structure is a Railway Bridge with a deck that will be approximately 22m in length and 1.5m in width with tiered stairs on either side of the structure. The railway bridge height will be approximately 3m and is designed to accommodate locomotives and carriages that travel along the railway track. CONSTRUCTION

with the construction phase and is applicable to the proposed technology alternatives.

Mitigations The following lists mitigation measures that

may eliminate or reduce the potential impacts listed:

1. Construction impacts will be the same as those described and assessed in the site construction impacts in section (a) above.

2. Construction of the raised pedestrian walkway will require deeper excavations but in a smaller area compared to Alternative A2. There would be 12 piers approximately 6m apart supporting the deck of the structure.

3. This river bridge will be founded on spread footings doweled into bedrock. This will require drilling into the bedrock on the edge of the river to attach the iron rebar and pouring of concrete at these locations.

4. Temporary water diversions may be required when constructing the spread footings at the edge of the river depending on the quantity of water flowing within the main river channel.

1. Mitigation measures will be as described above in section (a).

2. Construction will be carefully managed through the implementation of an EMPr, monitored by an ECO. Excavations within the wetland area will be carefully managed to ensure that the soil is only disturbed in the areas where foundations are to be located.

3. Drilling activity will only occur at isolated points at the edge of the river where the abutments will be located. Thus if carefully managed the impact can be kept within the construction footprint.

4. Should temporary flow diversions be required it would only be at the edge of the river where the abutments will be located. There would be no impediment to the river flow; water would merely be diverted around the work area as a dry surface is required for the concrete foundations to set. Any temporary structures or channels are to be removed once construction is complete. It is anticipated that the bulk of construction activity will take place




Page 24 of 47

within the dry winter months and thus it is unlikely that diversions will be required.

with the construction phase and is applicable to the proposed technology alternatives.



1. Construction impacts will be the same as those described and assessed in section (a) above.

2. Construction of the concrete pedestrian pathway will require shallower excavations however these excavations would extend the entire 70m of the proposed pathway and not just where the abutments would be in the case of alternative A1. This would create significant disturbance within the wetland area.

3. This river bridge will be founded on spread footings doweled into bedrock. This will require drilling into the bedrock on the edge of the river to attach the iron rebar and pouring of concrete at these locations.

4. Temporary water diversions may be required when constructing the spread footings at the edge of the river depending on the quantity of water flowing within the main river channel.

2. Construction will be carefully managed through the implementation of an EMPr, monitored by an ECO. Excavations within the wetland area will be carefully managed to ensure that the soil is only disturbed in the areas where the pathway is to be located. The surface disturbed will be approximately 140m

2. Compared to

the excavation for 12 piers approximately 6m apart which would disturb a smaller area during the construction phase.

3. Drilling activity will only occur at isolated points at the edge of the river where the abutments will be located. Thus if carefully managed the impact can be kept within the construction footprint.

4. Should temporary flow diversions be required it would only be at the edge of the river where the abutments will be located. There would be no impediment to the river flow; water would merely be diverted around the work area as a dry surface is required for the concrete foundations to set. Any temporary structures or channels are to be removed once construction is complete. It is anticipated that the bulk of construction activity will take place within the dry winter months and thus it is unlikely that diversions will be required.

3. Potential erosion of the surrounding area especially at the ends of the river bridge, destabilizing it and resulting in material loss which will enter the waterway.

4. Impact on the hydraulic functioning of the wetland area as a result of the pedestrian pathway will be more significant than the raised pedestrian walkway of Alternative A1.


6. When compared to the raised pedestrian walkway this structure is likely to require more regularly maintenance. The concrete slab will be prone to subsidence when compared to the raised walkway which is founded on piles. This structure will also have no railings as it is not of significant height, this also means that other modes of transport may use this access route which could further damage the pathway. Given that it will be located within a permanently wet area over time it will more than likely crack and land up as large pieces of broken concrete slab within the wetland.

4. The proposed pedestrian pathway traverses the entire wetland area. The structures footprint within the wetland is significantly larger than the raised pedestrian walkway. The pathway will run for approximately 70m within the wetland area. This location of the structure does have potential to affect the hydraulics of the wetland more than the raised pedestrian walkway.

5. Construction activity would create a significant impact in this section of the wetland for a short period of time but would then essentially remove potential future disturbance when residents attempt to re-establish their informal path.

6. More regularly maintenance has a cost implication and as such this structure is less feasible when compared to the raised pedestrian walkway of Alternative A1.

Page 27 of 47

Direct impacts:

1. Community members continue to make use of the old railway bridge to cross the stream, this bridge is however old and unsafe and pedestrians require a safer alternative. The narrow deck and awkward handrails make the use of the bridge treacherous for both young students and the elderly alike. The informal path within the wetland area will require ongoing maintenance and continue to degrade this natural area. Residents will continue to cross the railway track at an informal crossing point.

Indirect impacts:

2. Impacts on the local community and surrounding residents who are vulnerable to the hazards of using this route.

Cumulative impacts:

3. A number of individuals have already lost their lives while using the bridge either from the fall itself or drowning in the steady flow of the stream below. Without the construction of a safer alternative there could potentially be additional lives lost.

1. Damage to river banks and wetland area by construction vehicles. 2. Potential contamination of the surrounding environment with construction rubble and waste. 3. Potential generation of noise and dust.

Indirect impacts:

4. Residents will have to revert back to crossing the river, wetland and railway line without any structures.

Cumulative impacts:

5. Increase in the amount of waste sent to the landfill site. 6. Loss of social connectivity for community.


No-go alternative (compulsory) The impacts associated with operation of the Alternative A1 or Alternative A2 have been discussed in the above section. Indicate mitigation measures that may eliminate or reduce the potential impacts listed above: Alternative S1

Direct impacts:

1. Existing accesses must be used. Where no roads exist, tracks must be designated and marked out and vehicles must only use these designated and marked paths. No ad hoc roads may be created. The contractor must mark out the work area and minimum required construction area on the river/ wetland and vehicle access must be restricted to this area only. Vehicles may not access the river/ wetland at any other point than where construction is to occur. Where possible, heavy vehicle access to the river and wetland area must be restricted. Non-essential equipment and vehicles are to remain at least 15m from the river banks at all times. Materials may not be stored within 15m of the river bank and within the wetland. Vehicles are not permitted to operate along the river banks and within the wetland (except within designated construction area).

2. All construction rubble and waste would need to be disposed of appropriately at an appropriate land fill site.

3. The noise and dust generated would be a temporary impact during decommissioning only and would be negligible. Significant dust would be controlled through the use of a water cart.

Indirect impacts:

4. Ongoing risk for residents using the existing pedestrian pathway. Cumulative impacts:

5. Waste generated during the decommissioning will consist of building rubble and construction materials and general litter and will only be temporarily generated during the demolition period.

6. Residents remain disconnected from the surrounding facilities.

3. ENVIRONMENTAL IMPACT STATEMENT

Taking the assessment of potential impacts into account, please provide an environmental impact statement that summarises the impact that the proposed activity 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. Alternative S1 (preferred alternative)

It is the opinion of the EAP that all potential impacts that could potentially occur during the construction and operational phase of the river bridge, raised pedestrian walkway and railway bridge have been identified and key impacts and their mitigation measures are provided below. Key Construction Impacts: Damage to River and Wetland Area: Specific concerns would be heavy vehicle traffic operating in close proximity to the river causing banks to erode and collapse, resulting in sedimentation of the river. Storage of materials and soil within or near the river could also result in the deposition of these materials into the river leading to contamination of the river system. Construction activity within the wetland area also has potential to significantly impact the system through the compaction of the soil as well as damage to the vegetation leading to erosion and the undercutting and scouring of the proposed strucutures. Heavy vehicles should be kept at least 15m away from the river except where needed for the construction of the bridge. Vehicles operating within the wetland area must be restricted to within the area immediately adjacent to the construction footprint. As per the EMPr, no materials may be stored within 15m of the river or within the wetland and care must be taken to protect the river banks from erosion. No dumping is to be permitted within these areas. The above impacts are temporary in nature and can be mitigated but will require absolute compliance with the construction EMPr. These impacts are rated as medium. Key Operational Impacts: Overtopping and flooding of the river bridge resulting in damage to the bridge: The engineer has completed a hydraulic assessment of the catchment area and the bridge design has taken into account the water levels at various rates of precipitation and thus the




Page 29 of 47

river bridge should only be overtopped during extreme flood events. As such any inconvenience related to overtopping would be minimal. The proposed upgrade is aimed at resolving access issues in the area this impact is therefore rated as low. Impact on the hydraulic functioning of the wetland area: The proposed raised pedestrian walkway traverses the wetland area. The structure has been designed to limit its footprint and impact on the functioning of the wetland. Having a permanent structure that pedestrians are able to use will decrease the amount of regular disturbance within the wetland area as a result of frequent pedestrian traffic as well as regular maintenance activity along the existing pathway. Construction activity would create a significant impact in this section of the wetland for a short period of time but would then essentially remove potential future disturbance when residents would have attempt to re-establish their informal path. This impact is therefore rated as medium. Further to the above mitigation methods, an EMPr (Appendix F) has been developed to manage and control potential impacts. The EMPr should be implemented through monthly construction audits during which time recommendations within the EMPr should be enforced. If the EMPr is implemented correctly and the mitigation measures listed in this report are adhered to then the potential impacts associated with the construction of the river bridge, raised pedestrian walkway and railway bridge can be mitigated against. It is thus the opinion of the EAP that there are no significant environmental impacts associated with the proposal that cannot be mitigated against.

Alternative A1 (preferred alternative) - RIVER BRIDGE, RAISED PEDESTRIAN WALKWAY AND RAILWAY BRIDGE

Technology alternative A1 which involves the construction of a raised pedestrian walkway instead of a concrete pedestrian pathway will have a similar construction footprint compared to alternative A2. However, deeper excavation activity will occur at more isolated points (12 piers approximately 6m apart) within the degraded wetland area where the piers will be located. Alternative A2 will require shallower but more extensive excavations along the entire length of the concrete path (70m). The excavation activity required for the raised pedestrian walkway will disturb a smaller area of wetland soils as well as require less vegetation clearing. The structure has been designed to limit its footprint and impact on the functioning of the wetland. There are 12 piers supporting the deck approximately 6m apart. Once completed this would have far less impact on the wetland functionality when compared to the pedestrian pathway of Alternative A2. Temporary flow diversions may be required for the river bridge, however it would only be at the edge of the river where the spread footings will be constructed. There would be no impediment to the river flow as water would merely be diverted around the work area as a dry surface is required for the concrete foundations to set. It is the opinion of the EAP that Alternative A1 with the raised pedestrian walkway will prove to be more sustainable in the long term as this structure will cope better within the wetland area and have less impact on the functionality of the area in the long term. It will also mean lower maintenance costs and less need for ongoing repairs and construction in a sensitive area. From a social perspective it will also ensure that pedestrians can cross the wetland area without getting wet throughout the rainy season. Therefore it is believed that this alternative will ultimately have a smaller operational footprint and beneficial to the receiving environment.

Alternative A2 – RIVER BRIDGE, CONCRETE PEDESTRIAN PATHWAY AND RAILWAY BRIDGE

Technology Alternative A2 which involves the construction of a concrete pedestrian pathway instead of a raised pedestrian pathway would have a similar construction footprint compared to alternative A1.

Excavations within the wetland area will be carefully managed to ensure that the soil is only disturbed in the areas where the pathway is to be located. However, the surface area disturbed will be approximately 140m

2. Compared to the excavation for 12 piers

approximately 6m apart which would disturb a smaller area during the construction phase. The concrete pedestrian pathway’s footprint within the wetland is significantly larger than the raised pedestrian walkway. The pathway will run for approximately 70m within the wetland area. This location of the structure does have potential to affect the hydraulics and functionality of the wetland more than the raised pedestrian walkway. When compared to the raised pedestrian walkway this structure is likely to require more regularly maintenance. The concrete slab will be prone to subsidence when compared to the raised walkway which is founded on piles. This structure will also have no railings as it is not of significant height this however does mean other modes of transport (vehicles) may use this access route which could further damage the pathway. More regularly maintenance has a cost implication and as such this structure is less feasible when compared to the raised pedestrian walkway of Alternative A1. Temporary flow diversions may be required for the river bridge, however it would only be at the edge of the river where the spread footings will be constructed. There would be no impediment to the river flow; water would merely be diverted around the work area as a dry surface is required for the concrete foundations to set. It is the opinion of the EAP that Alternative A2 with the concrete pedestrian walkway will prove to be less sustainable in the long term as this structure will not cope as well as Alternative A1 within the wetland area and will have a greater impact on the functionality of the wetland in the long term. The potential subsidence of the concrete path resulting in the structure cracking and breaking would mean higher maintenance costs and increased need for ongoing repairs and construction in an area classified to be environmental sensitive. Therefore it is believed that this alternative will have a larger operational footprint.


Community members continue to make use of the old railway bridge to cross the stream, this bridge is however old and unsafe and pedestrians require a safer alternative. The narrow deck and awkward handrails make the use of the bridge treacherous for both young students and the elderly alike. The informal path within the wetland area will require ongoing maintenance and continue to degrade this natural area. Residents will continue to cross the railway track at an informal crossing point.

Stakeholders, Properties & Services 1. The contractor should liaise with local residents and pedestrians regarding restriction of

access during construction. 2. As standard construction practice the engineer and contractor should identify all existing

services that may be affected prior to construction.

Traffic & Construction Vehicles 3. Appropriate signage and barriers must be used to cordon off construction areas. 4. Speed limits must be obeyed. 5. All construction vehicles should be fitted with the appropriate silencers and exhausts.

Housekeeping, waste management, storage and materials handling 6. All hazardous materials and substances should be stored within a secured area in the

construction camp. The storage area should be a hard surfaced, bunded and covered area.

7. Littering must not be permitted on site. 8. Cement mixing must be done on a hard surface that is protected from storm water

runoff. 9. Contractors should be required to dispose of construction rubble at an appropriate

landfill site. Delivery notes and safe disposal certificates to prove appropriate disposal should available.

10. Appropriate and sufficient toilet facilities must be provided by the contractor. 11. Toilet facilities must be provided by a registered company and all sewage must be

disposed of at an appropriate facility. Safe disposal certificates must be kept on record.

Dust and erosion control 12. Exposed areas should be rehabilitated and re-vegetated as soon as possible during

construction. 13. A water cart should be used to dampen dusty surfaces and suppress dust. 14. Areas exposed to erosion must be protected through the use of sand bags, berms and

efficient construction processes i.e.: limiting the extent (footprint) and duration period that areas are exposed. The contractor must ensure that any blockages created during construction are resolved.

Stormwater management and protection of river 15. The engineer/contractor must ensure that only clean storm water runoff enters the

environment. Any contaminated run off must be collected and disposed of. 16. Only the area directly in the path of construction may be cleared and excavated. The

remainder of the river and wetland area must be demarcated as a no-go area. 17. No excavated material or fill material may be stored within the river/ wetland or within

15m of the river. 18. Any temporary diversions made in the river should not result in the impediment of water

flow, all temporary structures or channels to be removed once construction is complete. 19. Heavy vehicles should avoid working near the river or in the wetland as much as

possible. Bridge construction 20. Erosion protection features must be installed to protect the bridge structure i.e. reno

mattresses at appropriate locations on the river bridge ensuring that storm water does not erode the foundations and abutments of the new structure.

Specific conditions

· No person may utilise any water course for washing of any vehicles or equipment associated with the project.

· Should there be any negative impact on the recreation area (sports field) on the western bank of the KwaPata River adjacent to the proposed structure, these facilities must be re-instated prior to the contractor leaving site.

Geotechnical Specialist General Recommendations

· The construction should be performed in the drier winter months to minimise the effects of seepage. A sump and pump will be required to deal with the excessive seepage expected.

· Temporary excavations to reach founding levels may be cut to 35° maximum side slope or shored if steeper slope angles are required. It is recommended that a geotechnical professional inspect temporary cut slopes and founding levels.

· Backfill compaction should be performed in 200mm maximum loose layer thickness and compacted to a minimum 93% Mod. AASHTO (98% beneath bases). Vegetable matter (i.e. roots/grasses) must not be used as backfill nor must any boulders >2/3 of the compacted layer thickness be used in the backfill. The more granular material (i.e. TP7 0-2.6m / TP8>1.5m) is the most suitable for use as backfill with the more clayey/ silty alluvial residual material likely to prove difficult to compact. All foundation bases must be thoroughly compacted prior to casting concrete.

· Unless scour protection is employed, exposed soils must be grassed as soon as possible to prevent erosion. Consideration should be given to scour protection for KwaPata Bridge pier structures.
