Comments and responses[edit]

Is it possible to get the the planting list updated to include native species?
Is there a reliable set of estimated design infiltration rates for sites where only soil type is currently known? Additional tests will be conducted, but for now we are looking for numbers to begin an estimate, and a reasonable basis for those numbers.
The curators of Minnesota's stormwater wiki have conducted a very thorough literature review to establish their suggested values for design infiltration rates[1]. The lowest value on their table for clayey soils is 15 mm/hr, we believe that this is a reasonable estimate for clay soils. Designers may wish to add a safety correction to this number before undertaking their design calculations.
