Masonic Homes of California Flatland Development
The Facts:
The Masonic Homes of California is planning to develop the flat lands along Mission Blvd, from
Whipple Road to O'Connell Lane. The plan is a mix of rental and for-sale housing, retail space and
community facilities. They are currently seeking support from the Union City City Council and local
residents.
In November, 1989, Measure B was passed by the voters, which required the preparation of an Area
Plan for Union City. One of the goals of Measure B is "Encourage the continuation of agricultural
uses." In November, 1996, Measure II was passed that approved the Area Plan and provided that any
changes to the Area Plan would require voter approval.
The Area Plan for the Hillside Area, has the following policies:
Policy 9: Land use in flat lands along Mission Boulevard
Undeveloped flat lands in the Hillside Area along Mission Boulevard shall be retained in agricultural or open space use, or shall be used for recreation.
Policy 40: Preservation of the Masonic Home's surroundings
No development may occur on the flat lands immediately in front of he Masonic Home, or on the hill slopes behind the home where this development would have an impact on the visual setting of the home itself.
The land in question is within feet of the Hayward Fault line. The USGS estimates that the Hayward
Fault ruptures, on the average, about every 140 years. The 140th Anniversary of the last rupture, in
1868, was last year.
There are two key reasons to not allow the Masonic Home of California to continue with their
development plans:
1. Voters decided in 1996 to not develop the flatlands to the east of Mission Blvd. There is no reason to ask them again, just 12 years later.
2. It is ill advised to develop new homes within feet of the Hayward Fault.
