Operations staff presented two proposed additions to the district's low‑impact IPM product list to help recover athletic fields and treat infestations in stormwater swales. Staff described the first product, Pinergetic BZV, as an EPA‑exempt energetic deterrent intended to create a non‑harmful barrier to deter voles, moles, and gophers; staff said several California districts have used the technology with positive results. "It's essentially inert matter that is energized... It's not an actual chemical," the Staff member explained during the presentation.
Staff also proposed an aquatic glyphosate product for use in intermittent swales that cannot be treated with non‑aquatic herbicides; the presenter noted the product carries an EPA number and Oregon Department of Agriculture approval for aquatic use. Board members asked about application timing, re‑entry, respirable dust concerns for the powdered deterrent, and whether certified applicators would perform treatments; staff confirmed they would use district‑licensed certified applicators and standard posting procedures. After a motion and second, the board voted to add the two products to the district's low‑impact list.
