Budget estimate

$500,000 – $2,000,000

The RFP does not disclose a contract value. Based on comparable county complete‑streets design contracts in California, a full‑service engineering and environmental package for a mid‑size rural arterial typically ranges from $500,000 to $2,000,000, depending on scope depth, staffing, and duration. Factors influencing the final amount include the length of Redwood Drive, required environmental mitigation, and any supplemental construction‑phase services.
