A slope that is classified as 'steep' generally refers to what percentage?

A slope classified as 'steep' typically refers to angles or percentages that are noticeably inclined, which is why the range of 15% and above is commonly used as the threshold for steep slopes. This classification is important in various fields such as civil engineering, landscape architecture, and geotechnical engineering, as steep slopes can significantly impact drainage, erosion potential, and construction practices.

Slopes within the lower percentage ranges, such as 0-5%, 5-10%, and even 10-15%, are generally considered gentle and manageable for most land use practices, limiting the risks associated with erosion or landslides. In contrast, slopes exceeding 15% often require special consideration for design, maintenance, and safe usage, making this range the standard for what is seen as steep in most contexts.
