San Francisquito Creek
About the projectSan Francisquito Creek has a history of flooding homes and businesses in Palo Alto, East Palo Alto and Menlo Park. Flooding occurred in 2012, as recently as 2017, and the largest recorded flood event, since measurements began in 1930, occurred in February 1998, affecting more than 1,700 homes and businesses with more than $28 million in damages. The 1998 event was measured at 7,200 cubic feet per second (cfs) at the United States Geological Survey stream gauge upstream of the floodplain; this flow is now estimated by the U.S. Army Corps of Engineers to represent a 70-year flood event.
The cost of the Bay to Highway 101 portion is estimated to be $44 million.

Current:
The goal of the project is to provide flood protection to more than 5,700 homes and businesses in Palo Alto, Menlo Park and East Palo Alto. This multi-jurisdiction and multi-benefit project consists of three complementary projects where the floodplains intersect: along the creek from the San Francisco Bay to Highway 101, upstream of Highway 101, and along the Bay shoreline.
The SFCJPA ultimately intends to provide 100-year* creek and tidal flood protection** to all homes and businesses in these cities and remove parcels from the Federal Emergency Management Agency (FEMA) flood zone and from the requirement to purchase flood insurance.
* A 1% (or 100-year) flood has a one percent chance of occurring in anygiven year.
** Creek flood protection applies to flooding from a creek, as opposed to tidal flooding.

San Francisquito Creek upstream of Highway 101
San Francisquito Creek downstream of Highway 101
Upstream of Highway 101The project to address creek flooding along San Francisquito Creek upstream of Highway 101 is in the planning and environmental review phase, and includes a robust stakeholder process throughout.
Community input for the upstream of Highway 101 project has helped guide planning toward a project that will be both meaningful and achievable: meaningful, in that it can protect against a creek flow similar to the 1998 flood of record; and achievable, in that it is feasible in the near future, within regulatory and funding constraints.
The SFCJPA published a Revised Notice of Preparation (NOP) for a draft Environmental Impact Report (EIR) in December 2016. Four scoping meetings were held in January and February 2017 and two workshops and a site tour are planned for October 2017. Based on public input, several additional and optimized combinations of alternatives are being evaluated. The alternatives will be weighed against the project objectives and potential environmental impacts to determine a preferred alternative that, when implemented, would maximize flood protection and minimize adverse impacts to adjacent communities and the environment, seek to minimize requirements for new land easements, and, where possible, incorporate green infrastructure. The Draft EIR is planned to be released by early 2019 and will include a public comment period.
Simultaneously, the U.S. Army Corps of Engineers is preparing a similar federal document, an Environmental Impact Statement (EIS), to potentially aid in the implementation of a project.
Schedule• The SFCJPA Draft EIR is expected to become publicly
available by February 2019.
• The City of Palo Alto is managing a separateenvironmental review for replacement of the NewellRoad Bridge, and a Draft EIR is expected to be alsoreleased in early 2019.
• In 2018, Caltrans replaced the Highway 101 bridgeover San Francisquito Creek, which is a majorconstriction to creek flow.
• The SFCJPA is incorporating these evaluations toconsider cumulative environmental effects and optimumproject synchronization to minimize temporaryconstruction impacts.
Bay to Highway 101Flood protection improvements from Highway 101 to San Francisco Bay is complete. They will protect against a 1% (or 100-year) creek flow event during an extreme high tide, with more than several feet of sea level rise.
Features include a widened creek channel into the Palo Alto golf course, enhanced connectivity between the creek and adjacent marsh and improved access to trails and existing marsh habitat, including on a horizontal levee adaptable to sea level rise. New native vegetation will include tidal marsh, with pickleweed as the primary species as it is critical to salt marsh harvest mouse as habitat and food. Gumplant will be the predominate species in the transitional areas, providing important cover for the mouse and rail during high-tides. Other native species will be planted to increase diversity.
Funding SourceSanta Clara Valley Water District Through its November 2000 Clean, Safe Creeks and Natural Flood Protection Plan, the district secured $10.6 million for the planning and design of flood protection in the San Francisquito Creek watershed.
In November 2012, Santa Clara County voters approved the district’s Safe, Clean Water and Natural Flood Protection Program which included $35.5 million for the construction of the improvements designed for the Bay to Highway101 reach and remediation of channel constrictions upstream of Highway 101.
San Francisquito Creek Joint Powers Authority The SFCJPA received grant funds from the Department of Water Resources, which includes approximately $8 million from Proposition 1E funds and approximately $4 million from Proposition 84 funds for construction of the Bay to Highway 101 reach. It is actively pursuing additional funding from state and federal sources for construction of improvements upstream of Highway 101.
CaltransCaltrans is funding the construction of the Highway 101 Bridge replacement, as well as about 90 percent of the costs to replace the Newell Road Bridge.
San Mateo County jurisdictionsFor the Bay to Highway 101 segment, San Mateo County is contributing $2.06 million, the City of East Palo Alto is contributing $1.26 million, the City of Menlo Park is contributing $800,000, and the City of Palo Alto is contributing $400,000.
The SFCJPA and its partners are currently considering additional funding mechanisms to implement the SFCJPA’s long-term objective of removing all parcels in the San Francisquito Creek floodplain from FEMA flood insurance requirements.

Historical flood photos
The watershed and floodplain of San Francisquito Creek encompasses approximately 50 square miles from the Santa Cruz Mountains to San Francisco Bay, with the creek serving as the boundary between Santa Clara and San Mateo counties.
After the historic flood of 1998, the cities of Palo Alto, Menlo Park and East Palo Alto, the San Mateo County Flood Control District and the Santa Clara Valley Water District joined together to create the San Francisquito Creek Joint Powers Authority. In addition to addressing issues of flooding, the SFCJPA projects also provide ecosystem restoration and enhance recreational opportunities.
The SFCJPA is governed by a board of directors with elected officials representing each of the five member agencies. With the goal of transforming San Francisquito Creek from a divisive liability into a unifying asset, the SFCJPA plans, designs and implements projects from the upper watershed to coastal wetlands that are of mutual interest to these jurisdictions.
