The swale area is intended to be utilized for draining surface waters from adjacent roadways and private property by percolation of the water through the soil. The swales lying within the city’s boundaries, when properly constructed and maintained, effectively control the drainage of surface waters where there is an absence of other methods of drainage. The interference with the prescribed contours, the planting of trees or plants, and the use of materials which hinder the percolation of water through the swales seriously affect the drainage function of the swale areas, are a traffic hazard and health hazard, and cause damage to the road adjacent to the swales.
