This letter will demonstrate the impacts of the recent rain event upon the residents in the vicinity of the Darlington-Cedar Ravine intersection. Additionally, this letter will offer possible short and long term solutions. (It should be noted that because the worsening climate is an ongoing phenomenon, these solutions may be inadequate.)
On New Year’s Eve, 2022, an extreme amount of rain run-off flowed down Hidden Way and Darlington and veered off the street’s north edge into the backyard of the corner resident (3178 Cedar Ravine). The drain on Darlington’s north edge was incapable of handling the volume of water. (See video.) The residences negatively impacted by this run-off are 957 Darlington and 3160-3178 Cedar Ravine.
Ultimately, a significant amount dropped into the lower level of Kim Johnson’s home (3160); the rest into Cedar Ravine Creek.
A similar event occurred five years ago when a broken drain pipe released a geyser that flooded the above yards, garages, and under some homes. The City repaired the drain pipe and advised the residents that the problem was solved. However, as the current rain event unfolded, it became apparent that the problem was not solved.
A further complication is climate change itself. Politics aside, climate change is no longer a debate. It is a reality which municipalities must consider in their short and long range planning and budgeting. As we have seen, failure to do so will result in further erosion, property damage and – in extreme cases – possible threat to life.
A possible short term solution to the Darlington drainage issue is the placement of wattle along the north side of the road, from above the existing drain to the Cedar Ravine Creek bridge. This will prevent the flow of water from dropping over the road’s north bank at 3178 Cedar Ravine. Later, a pavement berm can be installed along the road’s north side, from the top of the hill down to the bridge. The berm will act as a kind of speed bump as it crosses the driveway at the bottom residence. A more long term solution would be to repave the road so that the cross slope is to the inside only. An adequate drainage ditch would have to be constructed on the inside to carry rain run-off all the way to the creek.
The signers below request that the City of Placerville ameliorate the flooding issue as soon as possible.
Thank you.
