A general feedback from a french user - I do not know the meaning of the acronym LIDA stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting., 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 harvestingThe practice of intercepting, conveying and storing rainwater for future use. Captured rainwater is typically used for outdoor non-potable water uses such as irrigation, or in the building to flush toilets.". 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.

  • 'LIDA stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.' has been added to the terms using the same definition for 'Low Impact DevelopmentLow impact development is a stormwater management and land development strategy applied at the parcel and subdivision scale that emphasizes conservation and use of on-site natural features integrated with engineered, small scale hydrologic controls to more closely mimic pre-development hydrologic functions.A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.'. We will continue to look for missing information of this type.

Do you have any specs for designing berms around a bioretentionA shallow excavated surface depression containing prepared filter media, mulch, and planted with selected vegetation. pondA body of water smaller than a lake, often artificially formed.?

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.
