Under the Municipal Improvement Act of 1913 and Improvement Bond Act of 1915, 1915 Act bonds can be issued by an assessment district to raise money needed to build improvements, such as streets, curbs, gutters and underground sewer and water infrastructure that generally enhance land value and give land utility. The properties that directly benefit from the improvements are then assessed an annual amount on the property tax bill. The direct charge you pay is used to make the payments of principal and interest on the bonds. If a 1915 Act Bond direct charge on the annual property tax bill is not paid in full by June 30th, the property may be subject to foreclosure by the levying taxing entity.
