Which evaluation is used to determine necessary drainage slope and landscape requirements?

The evaluation that is utilized to determine necessary drainage slope and landscape requirements is the surface evaluation. This method involves assessing the characteristics of the land’s surface, including its contour, texture, and existing water flow patterns. By evaluating these factors, one can determine the best drainage solutions that will prevent water accumulation and erosion, as well as inform the landscape design to enhance both functionality and aesthetic appeal.

Surface evaluation provides critical insight into how water interacts with the land, helping to guide decisions about grading, landscaping, and the installation of any necessary drainage systems. The emphasis on surface characteristics makes it clear that this evaluation is key for ensuring that the landscape is not only visually appealing but also effectively manages water runoff, which is essential for maintaining the health of the site and preventing potential flooding or water damage.
