While I strongly support keeping our cabins authentic, I believe fire safety should take precedence in horizontal decking which is very likely to spread a fire should an ember land on it. I'd note that the FS doesn't require that our roofs be covered in wood shingles, so I don't understand their reasoning.

Does the NFH have any stand on this issue, and would it support any kind of lobbying to change the FS policy on this matter?

Thanks.

Missing elements should be replaced in-kind where possible; if not possible they should be replaced with similar appearing materials. Natural or organic materials are recommended as replacement; concrete, steel, glass, and other may be allowed if appropriately used.

The R5 handbook is attached below for reference.

If the cabin tract has been determined have historical significance, there is a greater emphasis on the use of natural materials, however, exceptions can still be made. The following are references taken from the USFS Guide to Maintaining the Historical Characteristics of your Recreation Residence (page 22):

If the original porch, deck, railing, or any of its distinctive elements has deteriorated
beyond repair, replace the unserviceable pieces with new materials that match the original appearance, pattern, size, scale, proportions, textures, colors, and details.

Do not use substitute materials that change the appearance of the porch, deck, or railing, such as stainless steel cables. Substitute material that simulates the appearance of the original material may be approved on a case-by-case basis.

The District Ranger can approve a substitute material in our opinion. You make a valid argument that a composite decking material is a safer alternative with a similar appearance to the original wood material. We recommend you resubmit your request to the District Ranger, and/or if denied again, escalate to the Forest Supervisor (file an Administrative Appeal if necessary).
