Appendix H comments
-Incorrect references: It seems that hydrologic information was not intended to be reproduced in the handbook after all. If so, these reference to Appendix H in Appendix A should also be corrected or removed:
A-16 "C = dimensionless runoff coefficient, dependent upon land use (refer to Design Coefficients and
Nomograph Appendix H for reference to acceptable runoff coefficients). "
A-19 "TR-55 provides a graphical solution for the runoff equation, provided in Appendix H. Also, the National
Engineering Handbook provides the runoff depths for selected CNs in tabular form, also provided in
Appendix H."
-Suggest to make font color consistent for table headings where checklists are. If the heading background will be dark as shown, white has better contrast.
-Can the checklists be reproduced as tables that can be copied, instead of images?
-What is the purpose of the checklist on pages Appendix H-2 though H-5? It has more than is needed for a maintenance inspection and seems to include design evaluation or re-design (e.g. drainage area determination) elements that are unnecessary for just ensuring a BMP is functioning as intended. This purpose does not seem to be addressed in the handbook. It may cause unnecessary cost to BMP owners if professionals are directed to complete this expansive checklist that addresses more than just maintenance concerns for the BMPs, like the later BMP specific checklists do.
