An implementation schedule for Safe, Clean Water projects is available in Appendix C.
Delays in federal funding for many of the U.S. Army Corps of Engineers (USACE) projects have extended project schedules beyond the dates committed by Valley Water. Therefore, Valley Water is evaluating the option of proceeding with the local funding option on several of these projects.
2021–2025 Five-Year Capital Improvement Program :: III-3 Flood Protection Capital Improvements
Flooding on Coyote Creek caused by severe storm in February 2017 led Valley Water to reevaluate the schedule, level of flood protection, and funding sources for the Coyote Creek Project. A public hearing was held on June 13, 2017 to extend the Coyote Creek project to Tully Road and evaluate a project that would provide protection from a 20- to 25-year flood event. A preliminary cost range of $40-85 million was identified through a planning study and presented to the Board in December 2019. Based upon the project’s remaining secured funding of approximately $28 million, the project was deemed to have a shortfall between $12-57 million.
Staff worked with the Board CIP Committee to identify possible funding for construction of this project. In re- sponse to a recommendation from the Board CIP Com- mittee, on December 17, 2019, the Board directed staff to reallocate $21 million (uninflated dollars) from the Upper Penitencia Creek from Coyote Creek to Dorel Drive Proj- ect (Safe, Clean Water) to the Coyote Creek, Montague Expy. to Tully Road Project. The reallocation of funds would go towards addressing the Coyote Creek Project’s shortfall, while still leaving sufficient funds in the Upper Penitencia Creek Project to construct the local-funding- only project.
Additionally, in response to a Board CIP Committee rec- ommendation, the Board held a public hearing on January 14, 2020 to modify the Upper Llagas Creek Flood Protection Project local-funding-only key performance indicator (KPI) to increase the length of the project to be built by the available local funds from approximately 2.9 miles to approximately 4.9 miles. This modified KPI entails constructing Reaches 4 and 5 (portion), 7a and 8 (portion) as well as the onsite compensatory mitigation at Lake Silveira. The remaining Project elements, namely Reaches 5 (portion), 6, 7b, 8 (portion) and 14, will be built later once external or other funding sources become available.

Sunnyvale West Channel looking upstream from Java Drive PROJECT DESCRIPTION In the early stages of the project design process, Valley Water project team decided to join both improvement projects into a single flood protection project with a single Environmental Impact Report to reduce construction costs and minimize construction coordination issues between the two channels.
The West Channel extends approximately three miles and upgrades existing channel capacity to provide 1% (or 100- year) riverine flood protection for 47 acres of highly valuable industrial lands. The East Channel extends approximately 6.4 miles and upgrades existing channel capacity to provide 1% riverine flood protection for 1,618 parcels. Both projects decrease channel turbidity and sediment by repairing erosion sites, thereby improving water quality. e Provides 1% flood capacity for approximately 6.5 miles of channel along Sunnyvale East and approximately three miles of channel along Sunnyvale West within the City of Sunnyvale, protecting 1,618 properties (Sunnyvale East) and 47 acres (11 properties) of industrial land (Sunnyvale West). e Improves stream water quality by providing erosion control measures to decrease sediment and turbidity. e Identifies opportunities to integrate recreation improvements with the City of Sunnyvale and others as appropriate.
The Sunnyvale East and Sunnyvale West Channels were originally identified as separate projects. In order to improve efficiency by combining efforts, the planning, design and construction phases for both projects will be performed as a single effort. This project meets the commitments of the voter approved Safe, Clean Water Program (SCW). For a full description of the SCW benefits and KPIs, please visit www.valleywater.org. PROJECT LOCATION

Llagas Creek floods at Watsonville Road and the surrounding area
PROJECT DESCRIPTION This project continues a Clean, Safe Creeks project in partnership with the U.S. Army Corps of Engineers (USACE) and the state to plan, design, and construct improvements along 13.9 miles of channel. The project extends from Buena Vista Avenue to Llagas Road, including West Little Llagas Creek in downtown Morgan Hill. The federally authorized preferred project protects the urban area of Morgan Hill from a 1% (or 100-year) flood, and reduces the frequency of flooding in surrounding areas. Construction includes channel modifications and replacement of road crossings. Valley Water continues to work with Congress to aggressively pursue federal funds to bring this project to full fruition. In 2012, project limits were extended 2,700 feet upstream to Llagas Road to address public concerns.
This project is accounted for in the following: e 26174051 - Reaches 4-8 & 14 - Reimbursable - Lands, Easements, Rights of Way, Relocation, & Disposal e 26174052 - Reaches 4-8 & 14 - Construction/Coordination with USACE e 26174053 - Technical Studies (completed) e 26174054 - Design e 50C40335 - Construction, Reach 5, 6, & 7b
This project meets the commitments of the voter approved Safe, Clean Water Program (SCW), Project E6. For a full description of the SCW benefits and KPIs, please visit www.valleywater.org.

Typical natural tidal marshland in San Francisco Bay near the Shoreline project area PROJECT DESCRIPTION This project partners with the California Coastal Conservancy, U.S. Army Corps of Engineers (USACE) and key stakeholders to conduct an integrated, multi-objective project along the San Francisco Bay Shoreline. Project number 00044026 funded the USACE Feasibility Study effort for the North San Jose area, known as Economic Impact Area 11 (EIA 11) which was completed in FY17; this project number will continue to fund other Shoreline efforts outside of the Safe, Clean Water (SCW) project numbers. Valley Water's share of EIA 11 design and construction is $46.8M. Valley Water has been awarded a total of $61 million from a Measure AA grant to partially fund the design and construction of EIA 11. SCW funds will provide $15 million toward Valley Water's cost share of the design and partial construction efforts for EIA 11 and $5 million toward the Valley Water's cost share of the planning and design efforts for the remaining EIAs to accomplish the following objectives:
e Provide integrated fluvial and 1% coastal flood protection. e Provide protection for future sea level rise. e Restore and/or enhance tidal marsh and related habitats. e Provide recreational and public access opportunities. e Pursue continued federal funding. e Obtain a letter of map revision from the Federal Emergency Management Agency at completion of the Construction e Coordinate closely with the South Bay Salt Pond Restoration Project, City of San Jose, U.S. Fish and Wildlife Services, the community and key stakeholders. This project meets the commitments of the voter approved Safe, Clean Water Program (SCW), Project E7. For a full description of the SCW benefits and KPIs, please visit www.valleywater.org.

Flood Protection - Multiple Program Watersheds Project No. 62084001 Contact Ngoc Nguyen [email protected]
View of damage caused by burrowing animals along West Branch of Llagas Creek in the Uvas/Llagas Watershed
PROJECT DESCRIPTION This project plans, designs, and constructs repairs to levee and stream bank sites that have erosion damage. Each site requires a different type of repair based on location, severity, and velocities in the creek. The objective of this project is to restore the stream bank or levee to a stable condition so as to reduce the risk of flooding and/or damage to adjacent properties and facilities. For facilities with animal conflict damage, the objective is to repair the damage caused by animals and where applicable, install deterrents for future animal activities. The repair work consists of, but is not limited to: e Excavation and rebuilding of eroded soil material. e Installation of rodent barriers such as mesh or fabric. e Repairing the banks with methods commensurate with the extents of damage and environmental constraints. e Geomorphic channel restoration with bed and bank repair. e Outfall restoration and repair. e Sediment removal and blockage repair. e Fish ladder modifications and repairs.
