SSTS Records and Risk Assessment Project

In 2017, the county received a Clean Water Fund grant to conduct a records catalog and risk assessment. The CWF grant is for $100,000, with a 25% match, and it ends December 2019. The grant workplan includes: 1) collection and digitation of remaining paper records, including those from cities, 2) conducting a risk assessment countywide, using available data. The risk assessment will be a tool for county and local partners for prioritizing resources and assisting county and local officials with future planning. 2017 CWF Report
