The County Council requested a report from Road Services Division staff describing the location and condition of the County’s drainage trunk system within major road rights-of-way in unincorporated areas, the estimated accuracy of the resultant database, an analysis of the data to assess risks and impacts, and a prioritized program for maintenance. As Project Manager, RKI oversaw the condition and risk assessment of several thousand regional drainage assets and authored a strategic business plan to direct near- and long-term maintenance, repair, and renewal priorities.
