The city of McMinnville should develop a priority list of sewer system extensions and improvements that covers several years. Such a list, which would be nonbinding, would be a guideline for City expenditures for public sewer projects over a designated time period. The list would be useful in determining the appropriateness of annexation requests and other land use proposals. Priorities could be amended as circumstances change and allowances could be made for projects in which developers would pay for a substantial portion of the costs.
