Nothing in BC 3.08.005 through 3.08.030 shall be construed to require the City to provide water or sewer service to property outside the City. In addition to payment of the proportionate share of costs of an extension, the City may require a property owner to consent to annexation and may impose any other conditions the council considers necessary for the best interests of the City prior to authorizing a connection to the City’s water or sewer systems.
