Board directs lower cultivation tax rate, staff to publish draft EIR in May; public raises health, setback and ‘crop‑swap’ concerns

The Board of Supervisors voted to adopt a revised cannabis cultivation tax structure and received an update on the county’s planned environmental impact review and ordinance rewrite for cannabis land use.

Tax decision: Staff presented four options for cultivation taxation after an HDL analysis of verified canopy and market prices. After board discussion, the motion to adopt the option that equates a 2.5% gross‑receipts equivalent to per‑square‑foot rates passed on a 3–2 vote (yes: Hermosillo, Gore, Hopkins; no: Rabbit, Corsi). The board directed staff to read the new rates into the record so the ordinance can be brought back for adoption on the May consent calendar. The rates read into the record were: $0.36 per square foot (outdoor); $1.15 per square foot (mixed light); and $3.00 per square foot (indoor). The motion to adopt Option 2 was moved by Supervisor Hermosillo and seconded by Supervisor Gore.

Staff had recommended a 25% reduction as a moderate approach, but the board favored the conversion method (option 2) that ties square‑foot rates to a 2.5% gross‑receipts crosswalk. Staff cautioned that the cannabis program is supported by a limited fund balance and that the program is projected to be deficit‑funded in future years if revenues do not recover; the county will cover program costs while a revised ordinance and environmental review are completed.

EIR and land‑use proposal: Permit Sonoma presented the draft ordinance framework and a schedule. Staff said they plan to publish the draft EIR in May and return to the board with certificatory and ordinance actions in the fall. Proposed land‑use changes under study include: defining cannabis as a form of “controlled agriculture”; allowing a ministerial “crop‑swap” pathway (replacement of row/perennial crops by cannabis under performance standards); eliminating countywide caps and permit renewals (term limits); permitting certain supply‑chain uses as by‑right in commercial/industrial zones; and allowing limited visitor‑serving events in rural areas subject to use permits.

Setbacks and parcel rules under study include a proposed 100‑foot property line setback, a 600‑foot setback from residentially zoned parcels and a 1,000‑foot setback from sensitive uses (schools, daycare, public parks). Staff also proposed changing per‑parcel caps from 1 acre to 10% of parcel area and lowering the minimum parcel size for cultivation consideration from 10 acres to 5 acres in some zoning categories. Staff emphasized all of these are proposals under analysis; the EIR will evaluate environmental effects before any ordinance changes are adopted.

Public comment at length: More than 30 speakers addressed the item. Concerns ranged from health‑risk questions about terpenes (beta‑myrcene) and air dispersion, to compatibility with rural residential neighborhoods, to the risks of expanding cultivation in scenic corridors and near waterways (Marin County and Estero watershed concerns were cited). Farmers and industry representatives urged lower taxes or elimination of the cultivation tax, saying margins are already thin and vertical integration and retail competition are squeezing outdoor cultivation. Several speakers asked staff to treat ethanol extraction as non‑volatile so it can be allowed in industrial zones; staff indicated ethanol is being treated as non‑volatile for the purposes of zone permissions.

What happens next: Staff will publish the draft EIR for public review in May, continue technical analysis (including additional work on beta‑myrcene dispersion), and return to the planning commission and the board later in the year for hearings and ordinance action. The tax ordinance reflecting the board’s direction will be placed on the May consent calendar for adoption.

Why it matters: The board’s choice of tax approach and the eventual land‑use ordinance will shape whether, where and how cannabis production occurs in Sonoma County, with implications for public health, local agriculture, economic development and county revenues.
