Geothermal Campus-wide Master Plan Parks and Recreation Director Lonnie Brokke introduced Consulting Engineer Randy P. Christenson, P. E. with Karges-Faulconbridge, Inc. (KFI), who provided an executive summary of the City of Roseville's Geothermal Campus-wide Mas- ter Plan. Mr. Christenson provided a presentation of the Master Plan, dated May 19, 2008, detailing the benefits of an integrated campus system. The presentation and ensuing discussion with Councilmembers and staff included: phasing of the plan by replacing geothermal system at the end of their life expec- tancies; removal of the Fire Station from the phasing at this time; estimated pay- back over 15 - 20 years; potential and preferred locations for geothermal well fields; additional cost of geothermal over conventional systems, conservative na- ture of the estimates, based on 2008 energy costs, and depending on future energy costs; heating and cooling loads of city-owned buildings; and energy and cost sav- ings in transferring waste heat to the Public Works facility, with estimated pay- back for that building to be 16 years, and a 19 year payback for the Police facility and City Hall. Further discussion included detail of the schematic representation of the heat re- covery system; comparisons run times for 2006/2007 and 2007/2008 of the OVAL; gas consumption for City Hall and the Police Station, as well as Areas A and B of the Public Works facility; an environmental impact analysis; anticipated replacement phasing between 2013 and 2023 based on expected life spans on spe- cific equipment over the next 15 years; and recommendation for the geothermal field in the south parking lot versus the north, based on a campus-wide approach, and in consideration of the cost for well fields and bore holes, and cost impacts for adding additional wells now, or at a later date to avoid additional mobilization costs and potential cost increases. c.
