Project Description
This project addresses storm water conveyance infrastructure that drains into the Upper Llagas Creek Flood
Protection Project (ULCFPP) and the West Little Llagas watershed. The ULCFPP is a $120M project to build
channels, underground conduits, tunnels, and bridges to capture the flood waters from a 100-year storm in
Morgan Hill and eliminate the recurring flooding in the downtown and other parts of the City lying in the West
Little Llagas Creek watershed. The design is now 90% complete. The southerly Morgan Hill section (Reaches 7
and 7A) will begin construction in the summer of 2017. The northerly segment (Reach 8), including downtown
Morgan Hill, is scheduled to be completed in the 2020 timeframe, assuming sufficient construction funds are
acquired. Staff will coordinate with the Santa Clara Valley Water District to construct City-owned drainage
infrastructure in a manner that provides flood protection when the ULCFPP is completed.
Project Justification
The ULCFPP is critical to alleviating the persistent flooding in Morgan Hill. In addition, the project will allow for a
re-mapping of the FEMA flood plain in the City with the likely result that many properties will be removed from
the 100-year floodplain and the mandatory flood insurance that goes with lying in the floodplain. The ULCFPP
continues to be on the list of Council goals and priorities.
