When a property is developed, it is important to understand that changes to watershed characteristics (i.e., land use, slope, soil type, vegetative cover) will change the amount of stormwater runoff from the site. When a property is developed, it is important to understand that changes to watershed characteristics (i.e., land use, slope, soil type, vegetative cover) will change the amount of storm water runoff from the site. Ciaq = peak runoff rate in cubic feet per second i =rainfall intensityin inches per houra = drainage area in acresc = runoff coefficient (see table in pltw engineering formula sheet) c.
