Frequently Asked Questions

Have you ever wondered what a drainage map is? A drainage map is a map that shows the raparian zones and flood plains in an area. The raparian zones are the areas next to the water, and the flood plains are the areas that can be flooded. In simple terms, a drainage map is a graphical representation of how water flows through a select area

Drainage maps are used to help design bridges, roads, pipelines, and other similar infrastructure projects that need to account for how water flows in the region. They are also important in managing water resources and preventing flooding.

Most people who live in a city or a suburb think about drainage maps only when they hear their street is going to be dug up for repairs. However, these maps are also used by planners and engineers when they’re designing a new neighborhood, updating an infrastructure plan, or studying how climate change will impact the area. Real estate professionals may also use them to determine the value of a property.
