Abstract

The Lotus River originates from a stormwater retention pond in the Cape Town Airport Industria area alongside the N2. The river flows south through Gugulethu, Ottery and Grassy Park where it discharges into False Bay via the Zeekoevlei Wetland (an approximate 19 km stretch of river). The canal is an excavated channel which was constructed in the 1950s to accommodate the increased runoff due to post-war development in the Cape Flats, and has for the most part been formalised. Further urbanisation, combined with the reduced availability of land, has resulted in more communities finding they are living in the flood plain. Bergstan has been involved in the upgrades immediately downstream of the N2 to the Edith Stevens Wetland and detention pond, which restricts flow downstream. The primary intention of the recent upgrades was to accommodate a 1:50 year storm event, and to ensure that residents no longer reside within this flood line.
