Drainage to Prevent Erosion

Various drainage pipes and systems have been installed in the Sausal Cerek watershed to minimize erosion from seasonal rains (usually in Winter). Different soil types and plants make sections of the area more or less prone to erosion. In particular, strategic planting of shrubs and trees plays an important role in holding dirt in place on the hillside. Stormwater is a relatively new problem for this area — natural landscapes shift hydrologically over time, and erosion is a part of this process. However, urbanization and nonpermeable pavement limits where stormwater can join the groundwater system. As stormwater traverses urban areas, it can become polluted or, in severe cases, result in flooding. Specific studies and plans can be found on the Friends of Sausal Creek website.
