38. The Logan Public Library in Iowa serves long-term residents, “bedroom community” residents who work in Omaha, and all of Harrison County. A renovation is planned, especially to include access to more electronic volumes, modernized computer facilities, and quicker check-in and checkout. In addition, two small meeting rooms with modernized e-access are needed. The cost of the renovation, including cabling, will be $33,000, the new equipment will cost $21,000, and e-volume access initiation will be $17,500. Maintenance is expected to run an additional $3,500 per year, plus $4,000 for renewed e-volume access. The interest rate is 8 percent, the planning horizon is 10 years, and the building renovation is expected to have a salvage value of 30 percent, with no salvage value for equipment or e-volume access. It is estimated that an additional 2,500 visits to the library will occur in the fi rst year, increasing by 500 per year thereafter. It is estimated that the average benefi ts due to the new facilities, equipment, and access will be $2.00 per person per visit.
