What is the consequence of not addressing local drainage issues when filling an area?

When filling an area, addressing local drainage issues is crucial to prevent the alteration of natural water flow patterns. If these issues are ignored, the filled area can impede proper drainage, leading to an overflow of water onto neighboring properties, resulting in potential flooding. This flooding can cause significant damage to adjacent land and structures, aggravating the situation further.

Proper drainage management is essential to maintaining the integrity of the surrounding environment and preventing water accumulation in areas where it can create hazards. Thus, the answer highlights the important relationship between development activities and their impacts on local drainage, underlining the necessity for careful planning and consideration of potential consequences to neighboring areas.
