Take a look a this address : https://stormwater.extension.oregonstate.edu/standard-details There's plenty interesting plans with notes to see how to make important changes to the plans following the field reality!

Do the units check out for calculating the total depth of the stone reservoir? (i.e. should f' be in units of m/hr instead of m/day?)
- The notation used in the equations on Permeable paving: Sizing is being brought into line with the other sections of the site. At this time time units have also been brought into line to millimeters and hours as used for the other BMPs.

A general feedback from a french user - I do not know the meaning of the acronym LID, used profusely in this article, making it hard to understand. I think it would be very helpful to have a definition for all the acronyms by hovering the mouse cursor over them, just like you did in the sixth paragraph of "Targeting hard surfaces" with the definition of "Rainwater harvesting". This type of definition should be available for all the acronyms used in every other pages of this wiki, at least once per acronym per page.
- 'LID' has been added to the terms using the same definition for 'Low Impact Development'. We will continue to look for missing information of this type.

Do you have any specs for designing berms around a bioretention pond?
- Please see Berms

Is it possible to get the the planting list updated to include native species?
- Certainly! This information will be added as we review the plant tables in summer 2018.

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.
