Creates the Decennial Committees on Local Government Consolidation and Efficiency Act. Provides that within one year after the effective date of the Act and at least once every 10 years thereafter, each unit of local government (except municipalities and counties) must form a committee to: study local efficiencies, including an analysis of whether to consolidate with another governmental unit, municipality, or county; and create a report with recommendations regarding efficiencies, increased accountability, and consolidation. Provides that the duties of the committee include, but are not limited to, the study of the unit of local government's governing statutes, ordinances, rules, procedures, powers, jurisdiction, shared services, intergovernmental agreements, and interrelationships with other units of local government and the State. Provides that the committee shall collect data, research, analysis, and public input. Dissolves the committee after completion of its report and oral presentation of the report. Contains provisions about committee membership, meetings, and report requirements. Amends the State Mandates Act to require implementation without reimbursement. Effective immediately. House Floor Amendment No. 1 Provides that the 2 residents appointed to the commission shall be appointed by the board of the governmental unit (rather than appointed by the county board chairperson or the president of the board of county commissioners in the county in which the governmental unit lies). Removes a government studies representative from a community college or State university from the committee and, instead, provides that the committee may seek assistance from community colleges or universities with research and the development and review of reports of the committee. Provides that, at the conclusion of each meeting, the committee shall conduct a survey of residents who attended asking for input on what was discussed at the meeting (rather than allowing public input though at least one public survey sent to at least 10% of residents within the governmental unit). Allows the committee meetings to take place at the same time as the governmental unit's regularly scheduled meetings under specified circumstances. Removes a requirement of an oral presentation of the committee's report. Requires that the committee submit its report no later than 18 months (rather than 6 months) after the formation of the committee.
