(A) After analyzing the data and determining the site limitations, the drainage engineer can then develop a drainage system. He or she should work with the site planner and attempt to locate the buildings, roads, and parking lots to exploit the strengths of the site and overcome the drainage limitations of the site.
(B) The following are some points to consider in making these decisions:
(1) Fit drainage systems to terrain. The drainage engineer should attempt to tailor the drainage system to the existing site conditions. This will avoid unnecessary land disturbance and therefore help reduce the increase in runoff.
(2) Confine construction to areas not in drainageways. Any land disturbance in drainageways will necessitate the installation of more costly control measures.
(3) Cluster building sites together. Clustering building sites together outside of natural drainageways minimizes the amount of disturbed cover and helps reduce the increase in runoff.
(4) Minimize impervious areas. Keep paved areas such as parking lots and roads to a minimum. The more land that is kept in vegetative cover, the more water will have a chance to infiltrate, thus minimizing runoff.
