If you want to learn more about the streambank protocols supported in FieldDoc, we recommend checking out this resource webpage for the most in-depth coverage.
Questions that we often get about inputting protocols as practice types in FieldDoc include the following:
Q - If a project design is at less than 90% complete, you must choose 1 stream restoration practice, as opposed to multiple, even if multiple practices apply. Which protocol should I choose?
A - The reductions derived from the default methodology are the same calculation regardless of the protocol selected. This default calculation is simply a pound reduction value multiplied by the linear feet of stream restoration.
Default pollutant reductions for existing/non-confirming projects are 0.075 lbs/ft/yr for TN, 0.068 lbs/ft/yr for TP, and248 lbs/ft/yr for TSS.(Quick Reference Guide for Best management Practices, page 114 Table N-1-1, 2018).
Q - Why can we not apply more than one protocol to the same stream reach to calculate estimated reductions if our proposed approach will result in multiple protocols being achieved?
Per the expert panel protocol, projects that are planned and thus not constructed are required to use the default calculation to represent the entire project, regardless of the protocol(s) that is planned to be implementation. MDNR for its Trust Fund application allows users to use the defaults for projects less than 90% designed, applicants do not need 100% designs to utilize the protocol calculations.
It is up to the applicant to select the protocol that most represents their planned design, meaning the protocol that encompasses the majority of linear feet to be restored, and create a FieldDoc entry for this protocol. Per the expert panel, protocols are not additive when using the default calculation so only one default calculation is accepted per project that is less than 90% designed.
