Officials created the San Francisquito Creek Joint Powers Authority — a five-member coalition including representatives from the cities of Menlo Park, East Palo Alto and Palo Alto, the San Mateo County Flood Control District and the Santa Clara Valley Water District — to devise flood-prevention strategies after storms in February 1998 caused the creek to overflow. The floods affected 1,700 homes and businesses in the three cities and caused more than $28 million in damage. The JPA's ultimate goal is to protect more than 5,700 homes and businesses in East Palo Alto, Menlo Park and Palo Alto.
The completion of the first phase enables work to move forward on the second phase, which will provide stronger flood protection to the territory near the creek between U.S. 101 and the Pope-Chaucer Bridge. That area includes land in Menlo Park, East Palo Alto and Palo Alto, JPA Executive Director Len Materman told The Almanac.
This second phase will be broken down into two parts. The first will provide protection from a 70-year flood — an inundation that would be on par with the infamous flood of 1998. The second part will provide protection from a 100-year flood, and will require work with Stanford University to develop a plan to retain water farther upstream on university land. The creek is dammed at the Searsville Reservoir at Jasper Ridge, a Stanford-owned biological research preserve, Materman explained.
Work is underway to complete an environmental impact analysis identifying a "preferred alternative," or preferred method for completing the second phase of the project. The JPA plans to release a report by the end of February for public comment, he said.
The Army Corps of Engineers is also doing a federal environmental impact analysis and has identified the same preferred alternative, he added. He declined to describe what that alternative is, but said it will be released in the report.
The JPA is working on a funding package and will also apply for permits. If all goes well, project construction could begin in 2020, he said.
While officials had problems obtaining permits for the project's first phase, Materman said, he is hopeful that the one and a half years spent working with regulatory agencies will bear fruit and allow the upstream project to go through more quickly.
The end of the first phase caps more than 60 years of debate to finally address dangerous flooding along the creek, which has been exacerbated by upstream development that eliminated permeable ground that absorbed rainwater and the construction of homes and businesses in the flood plain.
Phase 1 of the project covered the creek and surrounding flood plain from San Francisco Bay to U.S. Highway 101. The improvements include a widened creek channel in East Palo Alto and at the Palo Alto Municipal Golf Course, which will help move water faster to the Bay and prevent backups; a horizontal levee that is adaptable to sea-level rise; and enhanced habitat and environmental improvements for wildlife and endangered species.
The project has also improved connections for pedestrians and bicyclists between the creek and adjacent marsh by adding a boardwalk at the Friendship Bridge between East Palo Alto and Palo Alto as well as improving trail access. The project will add thousands of new plants for wildlife.
The first phase restored a total of 22 acres of marsh. The Palo Alto golf course had the biggest gain in native habitat. Twelve acres of golf course land were used for widening the creek flood plain, Materman said.
The massive undertaking involved Pacific Gas & Electric's relocating a gas pipeline and cooperation with state and federal agencies to receive permits and protect the habitat for the federally protected salt marsh harvest mouse and Ridgway's rail. The California Department of Transportation also added another culvert and improvements to alleviate a constriction under US 101 during the highway bridge replacement on both East and West Bayshore roads.
On Dec. 14, as the storm clouds gathered, flocks of mud hens pecked in the shallows and the widened flood plain looking for insects while geese and ducks trawled the waters of the Faber Marsh. The rooflines of dozens of homes, which back up to the marshlands, still sit below the levee, a reminder of the times when the creek overflowed in major storms and the neighborhood flooded, putting lives at risk.
In December 2012, the creek again overflowed and damaged the protective mud levees, prompting then-East Palo Alto mayor Ruben Abrica to seek and receive an emergency declaration and funding from Gov. Jerry Brown for temporary repairs.
But now the homes, including that of current East Palo Alto Mayor Lisa Gauthier, are safe, said Gary Kremen, JPA chair and a Santa Clara Valley Water District board member.
Gauthier noted that, during one of the flood events that affected her street, she had put on her rain boots before venturing out. As she waded through the rising water, she wondered if she was going to need higher boots, she said. The dangers for East Palo Alto were particularly great because there are so many seniors living in the community, she said.
Abrica recalled that in 1998, when he was on the Ravenswood City School District Board of Education, he called out district school buses to help transport residents from the evacuated area.
Dennis Parker and his wife, East Palo Alto flood victims, lost everything in two floods from the creek, in 1955 and 1998. "We feel safe for the first time since 1998," he said.
Materman said the project will protect more than homes and property. The creek flooding also endangers and damages open spaces, local parks and the golf course. "You can be assured this creek will not threaten the spaces that you love," he said.
Concerns about the volatile and unpredictable creek and the effort to repair it have spanned more than six decades. After the 1955 flood, the Palo Alto City Council discussed working collaboratively with other jurisdictions, Kremen noted. But there was little forward movement until after 1998.
Receiving proper permitting from federal agencies concerned with wetland and endangered-species protections proved to be one of the most challenging aspects of the project, officials said.
U.S. Rep. Jackie Speier, who attended the Dec. 14 event, said she fought hard to get the permits so the project could move forward.
The U.S. Army Corps of Engineers was to receive $7 million for a feasibility study, but then-president George W. Bush's administration did not include the money in the federal budget, necessitating a local effort to fund the project.
"You notice that no federal money went into this project. If that was the case, we'd still be debating this," Speier said, lauding the power of local and regional collaboration.
During the ceremony Dec. 14, at about 11:30 a.m., the skies opened up and the rain began to pour as a squall blew across the new levees. State Sen. Jerry Hill, D-San Mateo, said it was fitting that the weather would turn rainy on the day of the project's unveiling.
"Let it rain. Let it rain. Let it rain," he said.
