$135$ : the urbanization process impact the design and construction of sustainable drainage systems in residential areas? Discuss the challenges posed by increased impervious surfaces, such as roads and buildings, on natural water flow and drainage. Explain how civil engineers develop and implement sustainable solutions, such as green roofs, permeable pavements, and rain gardens, to manage stormwater runoff effectively. Provide real$-$world examples of these solutions in use and their benefits to both the environment and urban infrastructure.
