Robert,
It's in the ASTM standard, C 1063, Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster
(Note, while we are not referencing "foundation" weep screed, we are referencing "weep screed", which, like "foundation" "weep screed" must be allowed to have room to ... well, "weep".) (underlining is mine)
- 7.11.5 Foundation Weep Screed — Foundation weep screed shall be installed at the bottom of all steel or wood framed exterior walls to receive lath and plaster. Place the bottom edge of the foundation weep screed not less than 1 in. (25 mm) below the joint formed by the foundation and framing. The nose of the screed shall be placed not less than 4 in. (102 mm) above raw earth or 2 in. (51 mm) above paved surfaces. The weather resistive barrier and lath shall entirely cover the vertical attachment flange and terminate at the top edge of the nose or ground flange.
Treat that weep screed (which is missing) as "foundation weep screed" (it serves that same purpose), and treat the roof as "paved surfaces" (the roof serves that same purpose).
