The City Council already did much of the heavy lifting by voting last year to approve a new tax on city water and sewer service that will top 30 percent by 2020. At that point, the new tax is expected to raise $239 million for the municipal fund. In 2014, aldermen raised the fee for emergency services on all landline and cellphones billed to city addresses by $16.80 a year to raise about $40 million that will be pumped into the laborers fund.
