TERMS OF REFERENCE In terms of our appointment by JN Venter Beleggings Trust, dated 3 September 2019, we prepared the civil engineering report regarding the preliminary investigation of the bulk services and preliminary investigation and design of the road/parking, storm water, sewerage and water systems that will serve the whole mixed development consisting of the existing Africanos Country Estate including the expansion of the resort. 2. SCOPE The scope of this report deals with the collection of data on and adjacent to Portion 228 and Portion A of Remainder Portion 74 of the Farm Commando Kraal Estate No. 113, Addo, Sundays River Valley Municipality, Eastern Cape and analysis of this data concerning an engineering opinion regarding the availability of bulk services, identification of constraints, further approvals and studies as well as the preliminary investigation and design of road/ parking, storm water, sewer and water systems to serve the above-mentioned development. The above information is required for the water and sewerage systems and storm water systems management plan that have to form part of the environmental report. 3. LEVEL OF SERVICES The level of services will be in accordance with the Guidelines for Human Settlement Planning and Design compiled under the patronage of the Department of Housing by CSIR Building and Construction Technology: (2000: Revision August 2003) and other acceptable design specifications. 4. DATA COLLECTION 4.1 Survey details The coordinated topographical survey of the site including existing structures, roads and services which was done by Surplan has been obtained electronically from JN Venter Beleggings Trust. The cadastral boundaries of the existing site and adjacent property were also indicated on the afore-mentioned survey by Surplan. The adjacent property (Portion A of Remainder Portion 74 of Farm 113), onto which the proposed expansion will take place, is in the process of being transferred to the JN Venter Beleggings Trust. 114 4.2 Proposed Expansion The conceptual schematic plan which indicated the total extension to the Africanos Country Estate was done by Ellis Architecture and Design Studio: Contact Person: Bobby Ellis. We obtained the layout electronically from the afore-mentioned architectural consulting firm on 9 September 2019. The current development located on 1.6ha consists inter alia of the following: • Africanos Inn • Restaurant • Function rooms • 12 x Chalets • Staff housing (6 Persons) • Associated infrastructure The proposed future expansion which will mainly be located on the adjacent 5ha property (Portion A), will consist inter alia of the following: • Double storey hotel (36 rooms) • 12 x Caravan sites & ablution building • Multi-function hall (200 seats) • Kids play area • Convenience store • 12 x Chalets • Staff housing (20 Persons) • New tool shed • New laundry • Demolish some existing buildings as indicated on the architectural layout In addition, and in order to ensure that the associated services (access, water, storm water and domestic effluent including laundry wash water) are effectively provided and managed, the expansion is proposed to include the following components: • Semi-dry storm water pond (3539m2 / 760m3) • 600mm diameter storm water pipe (subject to SANRAL approval) in R336 road reserve • New road/ parking area • New access to caravan park • Extension to existing syphon consisting of maximum 825mm diameter concrete pressure pipe • Foulsewer treatment plant (160m2), buffer tank (36m²) and irrigation pond (225m²/600m³) • Upgrade of existing foulsewer conservancy tank to septic tank • 110mm diameter sewer pumping mains and 160mm diameter gravity sewers • Sewer pump stations • 110mm diameter water reticulation • 450mm water pipeline from canal offtake to existing raw water tank 2 x new water tanks (12.3m diameter, 119m² each, 283m³ each) The total expanded development footprint is therefore anticipated to be approximately 4.8ha). 115 4.3 Field records and observations The main access to the site will be obtained via the proposed relocated access off the R336 road. The proposed access to the caravan park will off the Zuurberg Road. The proposed extension to the Africanos Estate will mainly be located on the south-eastern side of the existing resort. Refer to enclosed Drawing No. NV/2020-03/AS/01/A. The levels on the site vary from 53.0m above Mean Sea Level (MSL) near the top north- western corner, 51.07 near the north-eastern corner, 49.86 near the south-eastern corner and 49.65 near the south-western corner. The terrain slopes in general with very flat gradients from north-east to south-west and eventually in general from south-east to north-west along the R336 road. The surface areas where the proposed extension to the resort has been indicated consists mainly of citrus orchards, grass patches, open land and existing buildings which are proposed to be demolished. 4.4 Engineering geological report A detailed geo-technical investigation of the site area is not available at present. However, it is recommended to do an engineering geological investigation prior to the detailed design stage of the development. Based on visual observations of excavations in the vicinity of the site under discussion, the soil profile can in general be described as follows: • The topsoil mainly consists of clayey sand and/or gravel with vegetation and roots. • Over the biggest part of the site, the topsoil is underlain by loose to medium stiff sandy silty material from shallow to moderate depths. • In isolated cases the sandy silty layer may be underlain by a stiff to very stiff fractured calcrete layer. • Based on the current information at our disposal, the probability that a high groundwater table could be present in the area of the development is considered to be low. 5. ANALYSIS 5.1 Methodology The methodology adopted in analyzing an effective design for the wet services systems and main roads for the extension to the estate under discussion, consists of the following: 116 • Establishing acceptable objectives for the proposed road/ parking and wet services systems. • Determine appropriate design standards for the purpose of analysis and report. • Applying these criteria to the expected post-development conditions to confirm findings and details regarding the proposed design and constructed works. 5.2 Acceptable objectives • To provide flood control measures that prevent loss of life and significant damage to property from the run-off from major storms and keep excess run-off away from buildings and/or habitable units as far as practically possible. • To provide reasonable access to buildings and/or habitable units, effective water supply, effective domestic sewer, wash water and storm water drainage systems for the health, safety and convenience of the community and to protect property from damage by frequent storms. • To provide economical facilities and find solutions to accommodate water demand, domestic sewer effluent, wash water and storm water run-off problems compatible with the physical and ecological environment and protect the natural environment. • To implement procedures and practices which are consistent with the operating and maintenance standards of the accountable governing bodies and/or local authorities. 5.3 Appropriate design standards A balance must be achieved between the objectives, optimal land use and economic viability of the development. A compromise between the Guidelines for the provision of Engineering Services as published by the Department of Community Development 1983 (Blue Book), Guidelines for the Provision of Engineering Services and Amenities In Industrial Townships Development issued by The South African Housing Advisory Council 1994 (“old” Red Book) and Guidelines for Human Settlement Planning and Design compiled under the patronage of the Department of Housing by CSIR Building and Construction Technology: (2000: Revision August 2003) (“new” Red Book). The Guidelines for the Geometric design of Urban arterial roads (UTG1, 1986), TRH4 Specifications: Structural Design of Inter-urban and Rural road pavements and other accepted specifications as indicated, have generally been adopted as a basis for the design of the roads, water supply, sewer and storm water control systems.
