In my article last month, I briefly touched upon our December rainstorms. I want to address the topic again this month in more detail.
Visalia experienced 6.27 inches of rain in December 2010. We received 1.55 inches of rain on December 18-19 alone! Another big storm passed through the following week. It was the wettest December in Visalia’s history!
And yet, not a single home or business flooded. Lessons were learned from prior severe storm experiences. This time, City staff became aware of the pending storms based upon a National Weather Service forecast on December 12. Staff met on December 16 to discuss how to respond. On the order of Fire Chief Mark Nelson, an emergency operation center (EOC) opened at 4:15 a.m. on the morning of December 19, in the basement of the downtown police station. The EOC remained open for five days to deal with the impact of the storms on the community. At approximately 10:00 a.m. on December 19, City Manager Steve Salomon made a declaration of local emergency. The Visalia City Council affirmed that declaration at its meeting on December 20.
Our city has over 40 ponding basins. Currently, we own three portable, trailer-mounted pumps, and in this particular emergency we needed to locate and rent 10 additional ones. These can pump 3,000-4,000 gallons of water per minute. They were used to pump water from the ponding basins into adjacent creeks and ditches.
One of the major priorities occurred at the Mineral King and Linwood basin, located at Bruce McDermott Park. This basin quickly filled to overflowing, largely due to Caltrans pumping rainwater from adjacent Highway 198 into that basin. In order to stop the water from overflowing the basin, city staff got Caltrans to agree to stop pumping water into it from 198. Once the Caltrans pumps were turned off, rainwater filled the section of Highway 198 between Akers and Demaree, which resulted in the closure of Highway 198 for approximately eight hours. This reprieve from Caltrans pumping allowed city staff to operate an excavator and break the north bank of the ponding basin, which allowed water to flow from the basin into the adjacent Persian ditch, and from there west out of the city. After the water level lowered in the basin, the highway pumps were turned back on, the water in the Highway 198 depression was pumped into the McDermott basin again and ultimately out through the Persian ditch.
This is but one example of the swift city responses to emergency situations throughout the community. Several small basins overflowed or reached capacity but did not cause significant damage to private property. In most cases, these basins overflowed because lift station pumps were not able to move the water from the basins to canals. All functioned, but some were moving water very slowly because pumps became plugged with leaves. Kaweah Delta Water Conservation District and Tulare Irrigation District worked with the city to provide capacity in the channels for city storm water run-off. If this storm had occurred in the spring when there was simultaneous snow run-off, there would have been substantially more flooding problems to handle.
At the January 17 city council meeting, the council appropriated $968,000.00 from its general fund reserves to temporarily fund needed repairs, with the majority of that, $650,000.00, allocated to repair the sink hole at Ferguson and Shirk near Fire Station 55. We believe a large portion of these monies will be reimbursed from state and federal emergency funds. Staff will continue to assess our emergency response and will bring a report back to the city council at a future council meeting for further direction. Included in these considerations is the recommendation to purchase seven additional portable pumps with hose to be used in future such emergencies.
Again, I applaud the efforts of the city’s emergency response personnel in dealing with these storms and in minimizing the potential damage that could have been caused thereby. Perhaps FEMA could take some lessons from Visalia as to how to respond to such natural disasters!
