Relevant project experience
Financial Performance Management System, King County SWD, DNRP, WA: 2010 -2012
Developed a set of financial metrics for solid waste division operations, based on hard data regularly produced by the organization, and which has not been used by senior management since it was implemented in 2012. A summary of the system was published in the leading trade journal for solid waste administrators: Measuring Up. MSW Management, April 2010. A practical approach to performance measurement in an Enterprise Fund, adjusting for costs that senior management cannot control.
Solid Waste Transfer and Waste Export Plan, King County SWD, DNRP, WA, WA: 2007- 2011
This plan provided the blueprint for the future of the County’s solid waste management system and provided recommendations that will guide the County as it prepared for the solid waste system for waste export. After many internal studies and interaction with external advisory committees, won approval for a major rebuilding of its four largest transfer stations. This was to be financed entirely by bond funding, and for this purpose, Dr. Karston developed a 9-year debt structuring program, which optimized the funds required with the construction timing, and which was very well received by the Division’s outside advisory committees. This approach included the use of “short-term bond anticipation notes”, which ended up saving the Division about 4 million dollars in the first two years of the construction program. The system developed for this purpose was also published in the leading trade journal for solid waste administrators: How to Save Substantial Interest Expense. MSW Management, Nov/Dec 2011. Explains the merits and mechanics of using short-term Bond Anticipation Notes in a steep yield curve environment.
