The Central Stockton Lighting and Maintenance Assessment District was originally formed under the Street Lighting Act of 1931 when no cost variances were predefined and assessments were based on analysis of prior year lighting costs; this allowed for fluctuations in energy and maintenance costs. However, two laws in the 1990's altered the way in which government dealt with assessments. In 1992 changes were made to the Brown Act that necessitated longer notification deadlines before holding public meetings. In 1996, Proposition 218 mandated a ballot process to raise an existing assessment. Since then, in order to maintain this lighting district with no increases to landowners, all funds previously collected have been spent on energy costs. To continue to balance, these accounts required an increase in the amount landowners paid. In order to increase the amount of the assessment on parcels, the City of Stockton conducted a ballot election under Proposition 218 proceedings for approval by District landowners of the assessments against District properties. Siegfried prepared an Engineer's Report that describes the location of each of the five areas of benefit within the proposed Assessment District and the criteria used to determine the proposed assessments for each of the Zones for the 2011 Proposition 218 assessment ballot procedure. In addition, Siegfried compiles and submitted to the County the final tax roll for those districts that passed.
