PROJECTS
Line B Upgrades
Line B runs between Mowry Avenue (near the former salt evaporation ponds) and Cherry Street in Newark. Line B has been of concern to the District for a number of years. To better control stormwater flow, the District increased the Line B channel capacity at the Mowry Avenue crossing (completed in fall 2004), the Union Pacific Railroad crossing (completed in fall 2005) and the Cherry Street crossing (completed in fall 2006). This section of Line B now has enough capacity to handle a 100-year storm – so that the surrounding areas are less likely to flood during a 100-year storm.
After the improvements were complete, the District worked with FEMA to update the floodplain maps in this area. With the 100-year floodplain designation removed along Line B, nearby property owners are no longer required to purchase expensive flood insurance. While property owners are still encouraged to maintain flood insurance to protect their property, much lower rates will now be available.
Future Line B upgrade projects include capacity improvements at Glenview Drive, Farwell Drive and at the I-880 freeway crossing.
Line F-1 Improvements
In FY2008 and 2009, along Line F-1 in Newark near the Centerville District of Fremont, the Flood Control District focused on a number of preventative measures to improve flood control at Cherry Street, Sycamore Street, and Filbert Street. Construction for all three projects was completed in November 2008.
At Cherry Street near the Union Pacific Railroad (UPRR), a new 7-foot by 5-foot concrete box culvert was added parallel to the existing box culvert to convey a greater volume of stormwater runoff.
A similar project was built at Sycamore Street near the UPRR. Here a 7-foot by 6-foot concrete box culvert was added on to the existing box culvert to increase flood control conveyance capacity.
An unused box culvert along an abandoned portion of Filbert Street near Central Avenue had required District maintenance for many years. To reduce expenses while improving flood control, the District removed the box culvert and converted Line F-1 to an earthen channel.
The improvements to Line F-1 at these three locations comply with the newly updated FEMA floodplain criteria.
