ACTIVITY DESCRIPTION Describe the activity, which is being applied for, in detail 1. Introduction Tsolwana Local Municipality is proposing to construct a bridge over the Black Kei River at Becclesfarm, in the Tsolwana Local Municipality, in the Eastern Cape Province (Figure 1.1). Element Consulting Engineers, as the project engineers, has appointed EOH Coastal & Environmental Services (CES) to conduct the Environmental Impact Assessment. Figure 1.1: Location of the proposed Becclesfarm Bridge. Two alternative sites are proposed, site 1 and 2 as indicated in the map above. 1.1. Project location and description The proposed bridge construction is over the Black Kei River at Becclesfarm, a rural township located east of Tarkastad. Becclesfarm is accessed via a gravel road (approximately 15km) that branches off west of the R61. 1.2. Project components The proposed construction includes a bridge over the Black Kei River, which is intended to provide access to Becclesfarm. The main existing river crossing that provides access to Becclesfarm has suffered significant flood damage. A preliminary design for the proposed bridge is shown in Appendix C. 2. Biophysical Environment 2.1. Climate Becclesfarm receives approximately 335mm of rain per year, with the majority occurring during summer. The lowest (6mm) rainfall falls in July and the highest (60mm) in March. The average midday temperatures range from 15.1oC in June to 27.5oC in January. The region is the coldest during July when the temperatures drop to 0.6oC on average during the night. Figure 2.1: Average rainfall and temperature variation over a 12 month period in Tarkastad (Becclesfarm). 2.2. Topography Becclesfarm is characterised by flat bottomlands of intramountain basins with adjacent slopes. The study area is relatively flat. Elevation ranges from 1237 m.a.s.l (meters above sea level) to 1240 m.a.s.l. (Figure 2.2). Figure 2.2: Elevation profile of the study site, in Becclesfarm, Tarkastad. (Source: Google Earth). 2.3. Geology and Soils The geological strata of Becclesfarm consists of sedimentary rocks of the Tarkastad Subgroup (Beaufort Group, Karoo Supergroup) overlain with clay-loam soils typical of Da and Fc land types. 2.4. Vegetation and Floristics The vegetation of the Becclesfarm area is described by the SANBI National Vegetation Map (Mucina and Rutherford, 2006) as predominantly grassland, namely Queenstown Thornveld (Gs16), as shown in Figure 2.3 below. Queenstown Thornveld is found on flat bottomlands of intramountain basins with adjacent slopes supporting a complex of Acacia natalitia thornveld and grassland dominated by Aristida congesta, Cymbopogon pospischilii, Eragrostis curvula and Tragus koelerioides, with scattered shrubs and low Acacia in places. This vegetation is considered “least threatened” by Mucina and Rutherford (2006). Nearly 1% is statutorily conserved in the Tsolwana Nature Reserve. Some 10% is transformed, primarily by cultivation and urbanisation. Overgrazing is a serious concern, especially by goats close to urban areas. Figure 2.3: SANBI Vegetation map (Mucina and Rutherford, 2006) showing the vegetation type as Queenstown Thornveld (Gs16). 2.5. Eastern Cape Biodiversity Conservation Plan (ECBCP) The main outputs of the ECBCP are “critical biodiversity areas” or CBAs. Land use management of these areas is classified according to terrestrial Biodiversity Land Management Classes (BLMCs). No CBAs were noted in the area. The bridge sites are located in areas classified as BLMC 3 (Functional landscapes), with the following recommended land use management objectives: BLMC 3 (Functional landscapes): These areas should be maintained for sustainable development, keeping natural habitat intact in wetlands and riparian zones. Figure 2.4: ECBCP map of the surrounding area with the two alternative sites proposed for the bridge indicated as Site 1 and Site 2. 2.6. SANBI Working for Wetlands The following wetland type is found in great proximity to the study area: Channelled valley-bottom wetland which is a flat wetland dissected by and typically elevated above a channel, with most of its water inputs coming from the channel either as a surface flow, interflow, or from adjacent valley-side slopes. Water generally moves through the wetland as diffuse surface flow, although occasional, short-lived concentrated flows are possible during flooding events. Small depressional areas within such a wetland can result in temporary containment and storage of water within the wetland. Water generally exits in the form of diffuse surface flow and interflow, with the infiltration and evaporation of water from these wetlands also being potentially significant. Figure 2.5: SANBI map indicating the wetlands associated with the two alternative sites proposed for the bridge. 3. Socio-economic profile The proposed project is located in the Tsolwana Local Municipality of the Chris Hani District Municipality, in the Eastern Cape Province of South Africa. 3.1. Population The total population living in Tsolwana LM is 33 281 and 9494 households (Stats SA, 2011). The average household size is approximately 3.5 persons per household. 91% of the population is Black African, 5.8% are coloured, and 2.8% are white and the other population groups making up the remaining 0.4%. The population is made of 53% females and 47% males. 3.2. Income and poverty levels Approximately 23% of households earn a gross income of no more than R1 500 per month, another 16% earn between R1 500 and R2 500 per month.
