RECOMMENDATION(S):

APPROVE and AUTHORIZE the Chief Engineer, Flood Control and Water Conservation District, or designee, to execute the continuation of the Joint Funding Agreements with the United States Geological Survey (USGS) in an amount not to exceed $17,000 annually, for stream gauging, for the period from November 1, 2015 through October 31, 2020, and AUTHORIZE the Auditor-Controller to make payment for the Flood Control and Water Conservation District’s share of the cost.

FISCAL IMPACT:

The total cost of the stream gauging program for the period from November 1, 2015 to October 31, 2016, is $21,450. The FC District’s cost share is $14,250 and USGS’s cost share is $7,200. The FC District’s future years' cost will vary depending on the USGS budget resources and will most likely increase. The FC District share of the stream gauge maintenance cost will not exceed $17,000 annually without authorization from the Board. The FC District’s share will be funded entirely by Flood Control Zone 3B, fund 252000.

BACKGROUND:

Since 1962, the USGS and the FC District have been sharing the operation and maintenance cost of the stream gauge on San Ramon Creek at San Ramon under the USGS’s Cooperative Water Resources Investigation Program.

Long-term, continuous records of stream flow are essential to the calibration and verification of watershed runoff data used by the FC District for the design of all drainage improvements in Contra Costa County.

This gauge was installed in 1953 and has the longest continuous record of stream flows of any gauge in Contra Costa County. The continuous record collected at this site is also recognized for its unchanged upstream land use over the past 54 years. As a result of this consistency, other agencies also use this stream flow record to calibrate rainfall-runoff models. The current JFA language is the same as the previously approved JFAs.

Past FC District cost share was originally fifty percent (50%). In FY 2007-2008 the share increased to 60% and has been increasing slightly on a regular basis. The current cost share is sixty-six percent (66%).

CONSEQUENCE OF NEGATIVE ACTION:

Non-approval of the agreement would result in the loss of opportunity to obtain shared data used to predict storm runoff and to design flood control improvements.
