In my previously submitted calculations I used the average value from the range listed for "multi units, attached." Note this is the most stringent category, more stringent than the range listed for apartments. I also show calculation of an area weighted average runoff coefficient from various types of cover at the site. Using appropriate average values I arrived at virtually the same coefficient. I hope this information is helpful to the city.
