Improvement district invalid due to inaccurately weighted votes

Facts: A local agency established an improvement district for improvements to benefit all properties located within the district. The engineering firm hired for the project prepared a report allocating portions of the cost of the improvements to each property based on the benefits each would receive. The report allocated an improper dollar amount of benefits to the agency-owned property. The property owners and agency voted on the creation of the district, with each vote weighted according to the allocation of the costs to be levied against the property, based on the engineer’s report. Under the weighted voting, the improvement district was approved.
