Project Alternatives

Floodwalls height would slowly decrease from the max heights shown. Floodwall lengths include an estimated 100 feet of downstream floodwall added to the upstream floodwall distances presented by the SCVWD. Click to table enlarge. Use browser back to return.
Six Pope-Chaucer Bridge replacement alternatives have been presented or discussed in public meetings. The San Francisquito creek channel at the Pope-Chaucer site, without any bridge, has about a 40-year flood capacity. Alternative 3 and 4 have the same capacity as removing the bridge, alternative 5.

The largest flood on the San Francisquito Creek in recorded history was on February 3, 1998. The flood flow was about a 40-year event, so alternatives 3, 4 and 5 would effectively protect from a occurrence of a similar flood. With the No Project alternative 6, a 1998-type flood would produce a similar flood to 1998.

All six alternatives can achieve 100-year flood protection in the future, but the No Project alternative, keeping the current 15-year bridge, would require very extensive and expensive upstream diversion and/or detention.

Santa Clara County Water History

Image
Santa Clara County does love it's water and bridges - just look at the seal. Timeline from the SCVWD 10 Million B.C. Movement along the San Andreas Fault begins to create California's current coastal configuration. 500,000 B.C. A dropped valley (or graben) forms between the Hayward and San Andreas faults, approximately 500,000 years ago. The Santa Clara Valley is formed as well as the depression that eventually will become the San Francisco Bay. The Santa Clara Valley is an intermediate valley in the Coast Range between the Santa Cruz Mountains and the Gavilan Range on the west and the Diablo Range on the east. The valley extends in a south-easterly direction from the San Francisco Bay to an area near Hollister. 20,000 B.C. The last ice age ends. The resulting rise in water creates one of the world's largest estuaries, the San Francisco Bay. 3200 B.C. There is more water in the bowl-shaped Santa Clara Valley than its inhabitants can use. During the winter and ...

Stanford Favors a Flood-Control Fish-Passage for Searsville Dam

Stanford announced that it has preliminarily chosen to cut a culvert at the bottom of Searsville dam as its preferred option for allowing steelhead to travel past the dam.  If the flows exceed the capacity of the culvert, the dam will begin to back up water and reduce flood levels downstream. Searsville water contributes almost half of San Francisquito Creek's flow. "The key question is whether – and how – the sediment can be moved downstream," McCown said. "The possibility of releasing the sediment downstream presents a unique challenge that we must continue studying to ensure that we do the right thing, especially for the communities located downstream of the dam. "Our preferred approach does not preclude the possibility of someday removing the dam. But we have to be confident we don't ...

A Beautiful Concrete Arch Bridge

Image
Elliptical  arch concrete bridge with stone veneer Assuming that the Pope/Chaucer Bridge must be replaced, what kind of bridge would both function good and look good? One alternative to be considered is an elipitical arch bridge. The SCVWD's initially proposed design is functional for moving cars, but concerns have been raised about trees catching on the supports in the creek bed. Nobody says the SCVWD's initially proposed design looks good.  Typical SCVWD bridge design SCVWD's initially proposed Pope/Chaucer bridge design Existing Pope/Chaucer bridge Original Pope/Chaucer bridge Existing Pope/Chaucer culvert bridge design vs. original elliptical arch bridge design Oct 6, 2014 Construction has been completed on the innovative "Bridge in a Backpack" in Fairfield, VT. This bridge is one of only a few in the world to utilize Advanced Infrastructure Technology .
