While the charter provisions in Donohue expressly excluded zoning measures from the initiative process, we find Donohue to stand for the principle that where the charter establishes a procedure for the adoption of certain types of ordinances, that procedure may not be circumvented by use of an initiative petition. See also, Rice v. Stoff, 844 S.W.2d 529 (Mo.App. 1992), cert. denied sub nom. Carter v. City of St. Louis, ___ U.S. ___, 113 S.Ct. 3040, 125 L.Ed.2d 726 (1993) (Initiative not proper to propose ordinance providing for transformation of hospital to homeless shelter where initiative procedure would circumvent statute requiring public hearing on redevelopment projects.)
