The federal authorities approved a flood management venture to repair it in 1954, when Dwight Eisenhower was president. Now lastly, building to deliver the world as much as trendy flood requirements is nearing the ultimate phases.
Officers on the Santa Clara Valley Water District, a authorities company based mostly in San Jose, are embarking on the third and remaining part this month of a $241 million venture to enhance flood safety alongside 13 miles of Llagas Creek. The venture not too long ago obtained $80 million in federal funding, sufficient to complete the work.
“Downtown Morgan Hill was always flooding,” stated John Varela, former mayor of Morgan Hill, and now a member of the water district board. “The merchants were just devastated by the flooding. This project has a personal impact on all of us who reside in Morgan Hill.”
When the venture is completed in 2027, water district officers stated Monday, will probably be the biggest flood management venture the company has accomplished in 20 years, since work on the Guadalupe River in downtown San Jose, which led to the creation of Guadalupe River Park in 2005.
The Llagas Creek venture started in 2019. Development crews widened and deepened about 4 miles of the creek and its tributaries on Morgan Hill’s southern edges and Gilroy’s western edges. They completed that work in 2022.
For the second part, they dug a 2,000-foot lengthy tunnel underneath Morgan Hill, 12 toes excessive and 14 toes huge, close to West Principal and Hale avenues to take extra flood waters and transfer them away from downtown. That work completed final month.
For the ultimate part, GraniteRock Development, based mostly in Watsonville, will construct enhancements alongside 8 miles of Higher Llagas Creek and its tributaries, East and West Little Llagas creeks, from Freeway 101 to Llagas Highway.
Development will start subsequent Might. When completed in 2027, the venture will defend roughly 1,100 houses, 500 companies and greater than 1,300 acres of agricultural land.
Downtown Morgan Hill may have 100-year flood safety. Beneath that customary, the world is protected against floods so massive they solely have a 1-in-100 likelihood of occurring in any given yr.

The necessity for the venture was first recognized by federal officers 70 years in the past. However a sequence of delays, together with not discovering federal businesses to supervise it, different precedence tasks across the county, and most vital, lack of federal funding, moved it at a glacial tempo.
“There were other projects, little pieces done over the years,” stated Bhavani Yerrapotu, a deputy working officer on the water district who oversaw the latest work. “But we needed the federal funding to make the big pieces happen.”
The ultimate part will value $129 million, water district officers stated Monday.

Funding was permitted by the USDA’s “Small Watershed Program,” which protects agricultural areas from flooding. Many of the relaxation got here from Measure B, the Secure, Clear Water and Pure Flood Safety Program, a $67-per-home parcel tax permitted by Santa Clara County voters in 2012 and reauthorized by voters in 2020.
“We just never gave up,” stated U.S. Rep. Zoe Lofgren, D-San Jose, talking at a ceremony for the venture on Friday. “The people who are flood victims deserve that we keep going at it until we get the job done. We finally did piece together the funds.”
Already roughly 50,000 native crops and timber, together with willows, oaks, and sycamores, have been planted as a part of the primary two phases of the venture. When the third part is completed, one other 50,000 will likely be planted. The creek additionally has been enhanced to enhance handed for steelhead trout.
“This shows a great example of how when we all pull in the same direction and we never give up we can get the job done,” added Lofgren, who started looking for federal funding in 1996 for the venture.
