Summary
Watershed coordinator Sarah Carmichael reviewed the county's watershed assessment implementation matrix, highlighted priorities including riparian buffers, nutrient and bacteria reduction, water-quality monitoring and coordination with watershed management authorities, and said she is leaving the county position to work with a nonprofit.
Sarah Carmichael, Story County's watershed coordinator, presented an update on the countywide watershed assessment implementation matrix on Jan. 6 and outlined next steps for regulatory, programmatic and capital priorities.
Carmichael said the 2018 assessment established the county's water-quality baseline and that an internal working group has identified actions in three buckets: regulatory (ordinances and erosion control), programmatic (riparian buffers, Edge of Field work, source-tracking and outreach) and capital improvements (drainage-district projects and mitigation).
"We are halfway through the plan," Carmichael said, and she emphasized priorities that include mapping wetlands, identifying stream-erosion sites, expanding nutrient-reduction and bacteria-tracking work and updating GIS maps to reflect implemented conservation practices. She also described partnerships with Prairie Rivers of Iowa, watershed management authorities (WMAs) and statewide programs that could bring cost-share opportunities.
Board members thanked Carmichael for her work and noted that this was her last report to the board in her county role; she said she will continue conservation work with a nonprofit in Polk County and expects to remain available for collaboration. Supervisors praised the program she helped build and asked staff to continue coordinating on monitoring and PFAS and bacteria source-tracking efforts.
No formal board action was required; the presentation served as an informational update and farewell acknowledgment.
