Summary

City will proceed with targeted alum and herbicide treatments this year and staff are arranging training with Terry McNabb for board members on sample collection and in-field testing; consultant recommended annual low-dose alum and post-treatment monitoring.

Board members confirmed that the city’s initial alum treatment work is underway this year and discussed adding alum to future operating budgets for annual treatments. Staff (S2) said Terry McNabb will lead on-site postings and treatment and will provide training next week on how to use the newly arrived monitoring equipment so board volunteers can collect samples. "Terry's gonna teach you guys on Tuesday next week," a staff member said regarding field sampling training.

Consultant Katie Rodriguez recommended annual low-dose alum applications rather than a single large dose because Ocean Shores has continual groundwater phosphorus inputs; she also urged routine monitoring to evaluate effectiveness and adapt doses after a year or two. The board discussed testing logistics and the cost trade-offs of contractor-run tests (about $2,000 per event locally) versus in-house volunteer sampling and shipment to Ecology.
