Stone Harbor Updates: February 8 to 14

 

February 13

The work is moving well so far today, the western winds are keeping the tide well out so we have clear sailing on moving sand.  Its cold ( wind chill below 0) and ice covers the intertidal zone but it's caused no problems thus far.
The wind was at least 25 knots, gusting higher this morning and it was stronger last night. We are particularly worried about Today we won't spread the sand to avoid losing sand in the nascent and not well packed habitat areas.  We will place the un-spread piles on the windward side so as to minimize the loss. This is especially important as the National Weather Service predicts winds in excess of 40 knots from the NW this weekend.
We hope to complete one of the habitat areas next week and will act quickly to apply shell, which might help to reduce sand loss until the areas settle. Long slopes on all four sides of the habitat area should also help to resist the wind.
In any case we will know the outcome, thanks to Steve Hafner's team. He will be doing  elevations at various intervals over the next year to evaluate their resiliency. Losses can be expected.  Our project accounts for this by harvesting sand at the point where it is accreting. This allows for a long term maintenance with minimal cost.

Today was a world of difference from yesterday. The tides came higher than expected, still above the expected neap tide but lower than yesterday.  

The lower tides allowed the machines to operate at full capacity. They harvested sand from most of the lower section of the point before the tide rose to the mean high tide line, our lowermost limit. With three all terrain trucks we were able to move much more sand than we originally anticipated. We thought we could move 1500 cubic yards, but we are more likely to hit 2500 cy today.   

The borrow area from yesterday was engulfed by the tide yesterday and last night  leaving hardly a trace this morning. The two foot deep borrow was less than 6 inches this morning, recovering much faster than we expected. The two habitat areas have been fully marked by Steve Hafner's team and there is a substantial start on the fill.

The work started this morning at about 730 am. It took the two machine almost 15 min to just walk out. The tide flooded the point even though it ​shouldn't have. Last nights high should have been a neapy 3.8 ft but instead was a spring of nearly 4.8 ft. The machine made it ok though.
