===Fit the design to the terrain===

Using the terrain and natural drainage as a design element is an integral part to creating a hydrologically functional landscape.<ref>Prince George’s County. 1999. Low Impact Development Design Strategies: An Integrated Design Approach. Prince George’s County, MD.</ref> Fitting development to the terrain will reduce the amount of clearing and grading required and the extent of necessary underground drainage infrastructure. This helps to preserve pre-development drainage boundaries which helps to maintain distribution of flows. Generally, siting development in upland areas will take advantage of lowland areas for conveyance, storage, and treatment.
