Budget estimate

$250,000 – $500,000

The contract ceiling is listed as “$TBD,” but based on the quantified line items (306 shelters, 306 guards, 306 markers, 10 mowings, 10 weed treatments) and typical California prevailing‑wage labor rates, a realistic total contract value is likely between $250,000 and $500,000. Lower‑end assumptions use modest unit costs (e.g., $500 per shelter, $100 per guard), while higher‑end assumptions incorporate full labor, equipment, insurance, and prevailing‑wage premiums, pushing the total toward half‑a‑million dollars.
