RIVERDALE -- According to a recent report, the 2011 spring flooding in Riverdale could be classified as the worst in almost 50 years.
For 27 days in 2011, Weber River flows were definitely above the 10-year "recurrence interval." Usually runoff flows peak in mid-May but in 2011, flows were still raging through mid-June.
"While communities throughout Utah experienced significant flooding, Riverdale City was hit particularly hard," according to a report issued by RiverRestoration.org.
Although Riverdale minimized the extent of the flooding through city emergency response as well as citizen volunteers, significant damage to property and infrastructure was sustained. Channel instabilities in several areas may continue to threaten future damage to infrastructure and recreation areas, according to the report.
The report identifies between $760,000 and $1.239 million in flood damage repairs in Riverdale boundaries.
The flooding was so bad that the city declared a state of emergency on June 20.
The report identifies several areas affected by flooding in Riverdale, including the Weber River Parkway, Frisbee golf course, Riverdale Play Park, and Creekside trailhead.
In July, RiverRestoration.org suggested a fee of $15,141 to assess the flooding damage in Riverdale. The assessments may help the city qualify for FEMA funding of needed repairs.
Of 12 identified flood-damaged sites, FEMA approved two large projects for funding, meaning each will require around $350,000 in estimated costs to repair.
To use FEMA funds, Riverdale must come up with 25 percent of the costs. Donated land, materials, and volunteer time can be considered Riverdale's portion of the cost share.
