Upon receipt of the Planning Commission's resolution and report, the City Council shall hold a public hearing; provided, however, that if the matter under consideration is an amendment to change property from one district classification to another, and the Planning Commission has recommended against the adoption of such amendment, the City Council need not take any further action thereon unless an interested party requests such a hearing by filing a written request with the City Clerk within five working days after the Planning Commission files its recommendation with the City Council.
