engineer at least quarterly throughout construction and during the following
critical construction periods: removal of organic material and topsoil;
placement of under- drain and protective filter systems; installation of
surface drainage systems; placement and compaction of fill materials; and
revegetation. The professional engineer or other qualified professional
specialist shall be experienced in the construction of earth and rock fill
embankments. The registered engineer or other qualified professional specialist

photographs and to specifically and clearly identify the site.
