Or other tests or criteria MnDOT Specification 3601 Part A2a provides guidance for random riprap by referring the user to Table 3601-1 which outlines gradation requirements for random riprap. There are no additional requirements for this. Warnings are provided for rates that may cause drying shrinkage cracking.

To help municipalities property owners planners developers and others better manage stormwater runoff and reduce contaminants from entering our waterways we have developed a new guidance manual that provides information and guidance on innovative stormwater management practices including green infrastructure also known as low impact. Calculates concrete design mixture and materials based on WCS-4 319 criteria. Confirm local design criteria and applicability.
Specific treatment volumes may vary but 0-1impervious acre is typical. Include 012 ac-ft as a forebay within this volume.
