Corte Madera Creek Flood Risk Management Project

The Marin County Flood Control and Water Conservation District is seeking a qualified consulting firm to conduct an alternatives study and produce a 30 % preliminary design update for the Corte Madera Creek Flood Risk Management Project. The work focuses on replacing an aging fish ladder with a hydraulically‑neutral transition structure that does not increase Base Flood Elevations on any non‑District property. The consultant must attend a mandatory site‑visit, prepare technical studies (hydrologic/hydraulic modeling, fish‑ladder condition assessment), develop at least two viable design alternatives, and deliver a preliminary design package with cost estimates and an implementation plan. The scope also includes project management, monthly progress reporting, and coordination with the District. • Alternatives Study: data review, H&H modeling, feasibility of ≥ 2 alternatives, public workshops. • Preliminary Design Update: draft/final design drawings, cost estimate, permitting pathway, implementation plan. • Project Management: monthly updates, invoicing, meetings, compliance with District insurance and GIS data standards.
