Planning commission approves Hippo Harvest greenhouse and processing project with phased road and mitigation conditions

The San Benito County Planning Commission voted unanimously on May 12 to approve a multi‑phase conditional‑use permit and the associated mitigated negative declaration for Hippo Harvest’s proposed indoor/outdoor leafy‑green operation at 2370 Shore Road, northwest of Hollister.

Staff and EMC planners described the project as a phased development that would ultimately include a 45,000‑square‑foot processing building, roughly 25–30 acres of hoop‑house greenhouses, three 1‑megawatt combined heat‑and‑power microturbine units, and on‑site solar between greenhouse rows. Phase one is described as four acres of greenhouses with 10 employees per shift (two shifts) and limited infrastructure; full buildout was presented as supporting approximately 60 employees per day across shifts. Staff said the project uses private groundwater wells initially and would require a public water system permit when staff exceeds 25 employees; wastewater would be handled by an on‑site septic/leach field and stormwater managed through detention and permeable drainage features.

Commissioners focused on transportation, drainage, and neighborhood impacts. Public works recommended a phased list of frontage and access improvements and right‑of‑way dedications for Shore Road and Frasier Lake Road tied to specific project phases. Commissioners also pressed for clearer language on landscaping, periodic review of expansions, percolation testing for septic systems, and stormwater retention sizing.

To address those concerns, the commission approved the project with amended conditions. Key conditions added or clarified in the motion adopted by the commission include:

• Periodic review and expansion language changed so that any expansion beyond the approved project requires Planning Commission review; minor changes remain within the planning director’s authority under county code.

• The landscaping plan and any neighborhood‑protecting mitigation measures must be reviewed and approved by the Planning Commission.

• Right‑of‑way dedications: applicant must confirm whether existing Shore Road right‑of‑way meets the ultimate standard; otherwise the applicant must dedicate half of the 110‑foot Shore Road right‑of‑way along the property frontage. For Frasier Lake Road the applicant must confirm or dedicate half of the 60‑foot right‑of‑way. Dedications for Shore and Frasier Lake roads are required at specified phases; dedication for the roundabout area at Shore/Frasier Lake is required when the county designs the roundabout or during phase four, whichever is sooner.

• Phased improvements and contributions: prior to occupancy/operation for phase one the project driveway must be constructed to county standards; prior to phase two occupancy the applicant must contribute $180,000 toward Shore Road turn lanes (the figure reflects a county estimate for construction); prior to phase three occupancy the applicant must widen and improve half‑width of Frasier Lake Road to county standards; and prior to phase four occupancy the applicant must contribute $100,000 toward design/construction of a future roundabout at Shore and Frasier Lake.

• Traffic monitoring: applicant must retain a traffic engineer to biannual monitoring of actual traffic impacts across all phases and recommend mitigation when warranted; additional improvements triggered by monitoring will be required as appropriate.

Commissioners and the applicant acknowledged a time pressure: the applicant said the property purchase contract contains a near‑term deadline and asked for clear, enforceable conditions rather than an open continuance. The motion endorsed by the commission authorized the commission chair to finalize language and to ensure public‑works and geotechnical conditions are properly integrated into the resolution.

Vote and next steps: the motion carried on a 4–0 roll‑call vote. Staff will prepare a final resolution incorporating the approved condition language; the applicant and public works will coordinate phasing and schedule submittals for engineering and improvement plans.
