Flooding Mapping Tour


Step 1: Flooding Infrastructure

Begin by explaining what constitutes Flooding infrastructure:

  • Flooding infrastructure is essential to managing the impact of sudden and heavy rainfall or the gradual melting of snow and ice come springtime. This infrastructure can be designed and built – like sewers and drains, or natural like streams, ponds, trees and plants.

Step 2: Choose Your Study Area For Your Flooding Mapping Tour

In groups, discuss what should be the boundaries of your Study Area for the Flooding mapping tour.

Consider the following:

  • What are the areas in your school or home or neighbourhood where ponding or flooding typically happens?
  • What are the areas where water flow flushes pollution down the sewers?
  • What areas will capture most examples of Flooding infrastructure and Flooding issues?
  • How big is your school building and/or property?
  • What are the problems areas where it rains heavily?
  • Can you easily travel into the surrounding neighbourhood?
  • Are there naturas areas near you or is it mostly paved?

After discussing the questions above, the area that you choose for your tour and map will be your Study Area.

Step 3: Plan Your Tour

  • Create a map of your Study Area using Google Maps. - https://www.google.com/maps
    a. Click on the link and enter your school or home address in the search box.
  • Print off a copy of the map or draw a sketch of the map by hand while using the Google Map as a reference. If your Study Area Map is large, you may split the map into smaller areas and assign to groups.
  • Carefully study the boundaries of your Study Area. It is important that you know the boundaries of your Study Area and to stay within the boundaries!
  • Look over the Checklist (attached below) that you will use for your tour of the Study Area to note down the items that you are looking for. You can reference the Photo Gallery to identify things you don’t know or recognize on your tour.
  • Plan for your mapping tour during rain or right after rainfall to identify the areas where flooding generally occurs in your Study Area. Therefore, plan for wet weather!

Step 4: Explore and Map Your Study Area

  • Go out to your Study Area to locate and count all the different types of Flooding infrastructure you can find.
  • Note what is found on your checklist.
  • If you are able to do this tour during or right after rainfall, you will be able to observe water collecting, flowing, draining and pooling.
  • You may also find what pollution is going near or down the drains such as wrappers, cigarette buts and other garbage.
  • Mark what you find on your map.
  • Take photographs of everything you find. You can add them later to your Study Area Map!

Step 5: Talk About Your Tour

When you return back to your class or homeschool, compare your Checklists and Study Area Maps with other students.

As a class, dicuss the following questions:

  • What did you see and where did you see it?

  • Downspouts:

  • How many downspouts did you see?
  • How many went into the ground and directly into the sewer system or to a french drain, etc?
  • How many were disconnected and flowed onto the ground?
  • Were they discharging to the sewers directly?

  • Storm Sewer Drains:

  • Were any overwhelmed or backed up?
  • Could you see oil or chemical residues flowing from roads and parking lots?
  • Were there plastics, garbage or cigarette butts flowing into drain?

  • Flooding or Pooling:

  • Is water pooling?
  • Where is water pooling?
  • Is rainwater flowing away from buildings or towards them?
  • Where is water flowing close to the buildings and basements?

  • Is rainwater collecting where it shouldn’t?

  • Is water pouring off the school roof?
  • Can you find water with nowhere to go?
  • Is water pooling on the school’s roof?

Step 6: Complete Your Map

The whole class can work together to put all your work on to one big version that becomes your school’s Flooding Infrastructure Map. There are various ways you may decide to do this:

  • Project a map onto a screen or whiteboard, put everything on and save the image.
  • Create a wall display and add your Maps and Checklists.
  • Post a version of your Study Area Map and have threads projecting out to describe places on the map.
  • Take different images of student work to show that different students found different items.
  • Have your teacher help make a digital map with the infrastructure noted using a legend.
