Topography Analysis
How It Works
Our topography analysis tool looks at the contours and slope of your property to determine what percentage of the property is buildable, and creates a histogram to categorize the entire property's slope profile into 5 discrete ranges.
​
​
What is Considered Buildable?
Any slope that is 10% or less is considered buildable. We use this number based on a general consensus around cost and difficulty building when the gradient is over 10%.
​
​
How is a Property Filtered?
Any property with a buildable percentage less than the specified target will be filtered out. The default minimum buildable percentage is 50%, but we allow you to input any value you'd like as the minimum. If a property's slope is unable to be determined, it will still be included in your list.
​
​
What are the Histogram Categories?
Slope will fall into one of the five categories below, and we will include each of these categories as a column header with the percentage of the property that falls into that category for every property.
​
Flat (0 - 0.25%)
Easiest to build on
​
Gentle Slope (0.25 - 5%)
Still considered easy to build on. No significant increase in cost or difficulty building
​
Slight Slope (5 - 10%)
While still easy to build on, may require additional cost and incur some risk in building
​
Moderate Slope (10-15%)
Cost, difficulty and risks of building are increased
​
Steep Slope (15%+)​
​Cost, difficulty and risks of building are substantially increased. Not recommended for building
