consistant with a HUD document in 1999. The 1999 document gives tables and
examples of dry stack CMU, but provides for angled tie downs and height
limits for the dry stack CMU. The 1996 document does not have that much on
the tie downs.
BTW there is also FEMA 85 which gives guidance for foundations for
manufactured homes in flood plains.
