#EDU = Number of equivalent dwelling units
|
(# employees) x (20 gpd/employee) ÷ (225 gpd/DU) = #EDU
|
(# employees) x (25 gpd/employee) ÷ (225 gpd/DU) = #EDU
|
(# alleys) x (75 gpd/alley) ÷ (225 gpd/DU) = #EDU
|
(# car stalls) x (5 gpd/car stall) ÷ (225 gpd/DU) = #EDU
|
(# seats) x (2 1/2 gpd/seat) ÷ (225 gpd/EDU) = #EDU
|
(# beds) x (100 gpd/bed) ÷ (225 gpd/DU) = #EDU
|
(# bedrooms) x (100 gpd/bedroom) ÷ (225 gpd/DU) = #EDU
|
(# pupils and employees) x (75 gpd/person) ÷ (225 gpd/DU) = #EDU
