A resolution is a formal expression of the opinion, will, or intent of a municipal council. A resolution deals with matters of a special or temporary character, generally stating a position or policy of a city.
Whereas an ordinance is a legislative act and prescribes some permanent rule of conduct or government to continue in force until the ordinance is amended or repealed; a resolution is an expression of opinion or mind or policy concerning some particular item of business coming before the City Council.
