Description

The City of Orange is seeking a qualified consultant (or consortium) to develop 90 % complete plans, specifications, and engineering (PS&E) documents for the OC River Walk Upland Habitat Restoration Project, secure NEPA clearance, and optionally deliver the remaining 10 % PS&E and permitting after state review. The work encompasses geotechnical investigations, habitat restoration and landscaping design, river‑bank civil engineering, detailed surveying, and environmental compliance. Four hard‑copy technical proposals and four hard‑copy cost proposals must be submitted by the October 8, 2026 deadline, with a mandatory pre‑submission conference on September 17, 2026. • Scope includes 90 % PS&E for a 7.3‑acre upland‑habitat restoration, river‑bank improvements, and trail restoration, with optional 10 % PS&E later. • Required deliverables: geotechnical reports, habitat restoration plans, grading and trail design, NEPA documentation, and final design packages for State Coastal Conservancy review. • Consultant must be registered with California DIR, provide extensive insurance/bonding, and meet strict California state‑grant compliance (including State Coastal Conservancy acknowledgment).

Budget estimate

$1,000,000 – $2,000,000

No contract value is disclosed, but comparable full‑service engineering design contracts for similar habitat‑restoration projects in Southern California typically range from $1 million to $2 million for the 90 % design phase, with additional optional work potentially adding another $500 k‑$1 million. Therefore a reasonable estimate is $1‑2 million total. Factors influencing the range include the complexity of geotechnical investigations, NEPA documentation requirements, and the optional 10 % PS&E phase.
