Abstract
Team^2's goal was to design and install a permeable foot path at Catherine Zane Middle School.
Background
The team’s goal is to redesign or recreate a past done project that did not meet the schools criteria. It is a section of the peace garden at Zane Middle School, it should meet all the criteria for a permeable path.

Testing Results
We ran three tests of permeability on each prototype ratio. To test our prototype slabs we built a box of wood around the slab and siliconed the inside corners. After this we filled the wooden box holding our prototype slabs with two water balloons filled with approximately 2 gallons of water. We then popped both of the balloons at the same time and timed how long it took for the water to permeate through the path. The table below contains the results of our tests.
| Trials | 2:1 ratio | 3:1 ratio | 4:1 ratio |
|---|---|---|---|
| Trial 1 | 7.08 sec. | 5.14 sec. | 3.59 sec. |
| Trial 2 | 6.72 sec. | 5.13 sec. | 3.42 sec. |
| Trial 3 | 7.03 sec. | 5.13 sec. | 3.49 sec. |
Maintenance
This type of permeable walkway only needs to be maintained about twice a year. The most effective way to maintain this path is to power wash it two times a year. This ensures that small objects will not clog the holes in the path way.
Instructions
This is how to maintain. The step by step how to template {{How to}} is most likely best for this part.
Troubleshooting
This is only how to troubleshoot basic operation. For complex issues, the solution might just say contact ________. It should be a table in this format:
| Problem | Suggestion |
|---|---|
| Example issue | Example solution or suggestion |
| Does not turn on | Make sure it is plugged in |
| Another issue | Et cetera |
Discussion and next steps
Suggestions for future changes
This is where to lay out suggestions for how to make the project function better in the future.
