X The storm drainage plan shall adequately address the number of catch basins
required to handle the parking lot and hard surface runoff. The Uniform
Plumbing Specialty Code [UPSC, Section 1108] allows a maximum 6" outlet on
each catch basin, and Table 11 -2 limits the maximum surface area one catch
basin can serve to 7,133 square feet at 1% slope of the horizontal line from the
catch basin. Additional catch basins are required to adequately serve the area.
Sizing of all storm drain piping is determined by OPSC, Table 11 -2. If an
engineered system is to be used in lieu of a table 11 -2, two sets of plans
stamped by an engineer licensed in Oregon and the hydrodynamic calculations
must be submitted for review and approval.
