Flood Project Plan

The Flood Project Plan represents many years of planning and stakeholder coordination.

The Flood Project Plan is designed to provide a variety of public safety, economic, recreational and environmental benefits to the Truckee Meadows region.

Its primary goal is to create a more resilient community by reducing flood damages and deaths resulting from a 1997-type flood event (117-year event). Additionally, the Plan incorporates certain recreational and ecosystem restoration features within the footprint of the flood protection infrastructure.


The Flood Project Plan is based on the "Living River Plan," originally conceived by the Flood Project Community Coalition. Over a period of six years, our agency organized hundreds of meetings with community stakeholders in order to develop and build consensus for a regional flood management plan.

The Living River Plan emphasized the community's vision of incorporating environmentally-friendly elements into the flood protection infrastructure ("green" infrastructure) in order to reconnect the river to its floodplain, restore habitat for native species, and enhance recreational opportunities along the river.

The Living River Plan was eventually presented to the U.S. Army Corps of Engineers (Corps) as the Locally Preferred Plan (LPP) alternative for flood risk management. 


TRFMA is committed to building a cost-effective flood project to benefit our community. In response to local concerns regarding the overall cost and scope of the Living River Plan (which was estimated to cost $1.6 billion), TRFMA worked with its consultants and numerous stakeholders to revise the plan, significantly reducing the cost while still providing a 100-year level of flood protection for the Truckee Meadows (thereby maintaining compliance with the National Flood Insurance Program).

Through a series of meetings—including an in-depth Value Engineering exercise, the overall cost was reduced to just $446 million. This represents roughly 72% in cost savings to the communities of Reno, Sparks and Washoe County.

The current Flood Project Plan retains some of the elements from the original Living River Plan and incorporates results from our updated hydraulic models.  


Over the years, TRFMA has worked diligently with the U.S. Army Corps of Engineers (Corps) to implement the Flood Project. Unfortunately, due to recent federal budgetary constraints, the Living River Plan was not recommended by the Corps for Congressional authorization.

However, as part of the Water Resources Reform and Development Act of 2014 (WRRDA 2014), Congress authorized and pledged almost $200 million in federal funds to construct the Corps National Economic Development (NED) Plan, which is designed to provide 50-year flood protection for the Truckee Meadows.

With the help of its lobbyists and delegates, TRFMA was able to draft a special piece of legislation to benefit the Truckee Meadows. Section 1036 of WRRDA 2014 directs the Corps to build a Locally Preferred Plan that provides a higher level of flood protection than the authorized NED Plan as long as the LPP meets certain Corps requirements.

Per Section 1036, the Flood Project Plan—which provides cost-effective 100-year flood protection for the Truckee Meadows—can be constructed with federal support, including funds authorized for the NED Plan (almost $200 million).
