Once the planning is done and the city can give a good estimate of the cost of the effort, the service district and additional tax has to be approved by 75% of the property owners who will pay it. The city also requires owners of at least 50% of the property value of a district to approve it, to prevent several small property owners from overriding one larger one or vice versa. The plan right now is to have voting done by mail after a series of public meetings.
