Flood Management Plan
UPDATE: Zone 7 FMP Public Meetings
In January 2026, the Zone 7 team held three in-person public meetings in Livermore, Dublin, and Pleasanton to provide an update and seek community input on the Flood Management Plan (FMP) and the potential projects under consideration.

Zone 7 continues to seek community feedback/input on the potential projects under consideration for the Dublin, Livermore/Eastern Alameda County, and Pleasanton/Happy Valley/Sunol areas.

Flood Management Plan Background
Recent, relatively minor flood events have caused widespread damage to Zone 7’s 37-mile flood protection system. Channel bank erosion and sedimentation have led to costly repairs. Moreover, the confluence of factors such as urbanization, population growth, climate change, aging flood infrastructure, and changing environmental regulations has exerted additional stress on the flood protection system.
Zone 7 is proactively addressing these challenges by developing a comprehensive Flood Management Plan (FMP) that will optimize flood management across the Livermore-Amador Valley region, encompassing the entirety of the Zone 7 flood protection system. This initiative is aligned with District Act 205, as modified by Assembly Bill 1125, and is harmonized with Zone 7’s overarching Strategic Plan. FMP formulation is further informed by prior planning studies.
The FMP is a high-level flood management strategy. The FMP Phase 1 document, published in September 2022, outlines the goals and objectives of Zone 7, describing “what” needs to be accomplished to reduce flood risk. The FMP Phase 2 document--currently under development--will describe “how” to achieve these goals and objectives with means/methods that are both practical and comprehensive.
The FMP will be updated every five years, or as conditions dictate.
Zone 7 completed a comprehensive evaluation of its flood protection system and shared results in May 2025. This evaluation was a key step toward the future FMP, a comprehensive plan to address current and future flood risks in the Tri-Valley area.

FMP Guiding Principles
Seven guiding principles direct Zone 7’s conduct of flood management and form the basis for the FMP.
Align with Zone 7 Strategic Plan
Foster public engagement
Do what is needed and practical to manage flood risk
Account for climate change
Be risk informed
Advance stakeholder collaboration
Provide multi-benefit solutions
FMP Phases
Phase 1
The Phase 1 document looked at what will reduce flood risk by:
- Describing the existing Zone 7 flood protection system and protected areas
- Describing the existing and future flood risks posed to the system and protected areas
- Establishing goals and objectives to reduce flood risk
Phase 2
The Phase 2 document will describe how to implement what was identified in Phase 1.
The Phase 2 document is currently being developed.
The Phase 2 FMP will:
- Specify existing and future risks
- Develop, evaluate, and prioritize proposed solutions
- Provide guidance for risk-based, proactive maintenance of the flood protection system
- Engage stakeholders and the public
