The need for rehabilitation of the road has been determined by the deteriorating condition of said road. As such, the proponent identified the need to investigate the feasibility of rehabilitating the road to fulfil its mission of achieving a safe and efficient national road network in Namibia. The feasibility study further aims to determine possible sources for material (borrow pits) which will be needed for the road rehabilitation activities. The subject road is approximately 173 km long and extends from Grootfontein to Rundu. The road starts 3 km south of the Taranaki Farm entrance gate and ends at the Rundu Town main junction (Aurecon, 2019). The first portion of the road, TR0802, is in the Otjozondjupa Region. TR0803 is situated mostly in the Kavango West region with a small section at Rundu in the Kavango East region. This report documents the assessment of potential impacts from the proposed activity. The preliminary findings within this Scoping Report indicate that potential impacts will be of a low significance. These potential impacts can be further mitigated by implementation of an effective Environmental Management Plan. Based on the information provided in this report, GCS is confident the identified risks associated with the proposed development can be reduced to acceptable levels, should the measures recommended in the EMP be implemented and monitored effectively. It is therefore recommended that the project receive Environmental Clearance, provided that the EMP be implemented. 19-0640 16 January 2020 Page 3 Roads Authority TR8/2 AND 8/3 ROAD REHABILITATION
