SECTION 607. CONTRACTS.
   (a)    Council Action. No contract, for any purpose, shall obligate the City, in any manner, unless and until such contract has been approved or ratified, in written form, by the affirmative votes of not less than three (3) members of the City Council, except:
      (1)   Where a contractual expenditure by the City budget adopted by ordinance, City Council approval thereof shall be conclusively presumed; and
      (2)   Where the City Manager reasonably determines that an emergency immediately required the obtaining of goods or services, he/she shall be empowered to contract for the same without prior City Council approval, and such contract shall be a binding obligation of the City. The authority of the City Manager hereunder as to a particular emergency shall terminate at the next meeting of the City Council unless specifically extended.
   (b)    Leases. No agreement for the lease of City-owned real property to any person, for a non-municipal purpose, shall be valid unless the City Council finds that the property proposed for such lease is not required, and will not be so required during the term of the agreement, for municipal purposes.
   (c)    Supplies and Equipment. Notwithstanding the provisions of this Section relating to contracts, the City Council shall, by ordinance, provide for the acquisition of equipment, materials or supplies, other than for public works contracts, if same are included within a budget approved by the City Council.
   (d)    Public Works Contracts. Except as otherwise provided by ordinance, the City shall contract for the construction or reconstruction of any public building, works, streets, drain, sewer, utility, park or playground (hereinafter "Public Project") in the time and manner and in accordance with general law.
      (i)   In determining the lowest responsible bidder, the City Council may give reasonable preferences to local contractors.
      (ii)   The Council may, by ordinance, determine which contracts will require competitive bids, bonds, insurance and other such requirements, and which will not.
