More on North Main Avenue Construction

The photo above was taken last Thursday.  The reflection of the arched dome has created an illusion that the culvert is a complete circle.  Because the worksite was flooded all week,the contractors were unable to work.  Later on Thursday, a larger pump was brought in and it began pumping down the area on Friday.  By Saturday morning, the level of water had dropped about 3 feet or more.  Another large pump was brought in Saturday morning.  Sunday was a day of heavy rain and by tonight my rain gauge had 1.18 inches of rain.  The watershed for Gee Creek is 8.7 square miles.  A one inch rain on the watershed dumps 150 million gallons or more.  Some of this water is soaked into the ground  or stored in ponds and wetlands or storm water facilities.  The water that makes it to the creek can only go through the North Main Avenue crossing.  With the extra pumping today, the water level stayed about the same.  The National Weather Service is predicting another round of heavy rain early Tuesday.  This could be a real problem:  The high flows on the creek today will not have much time to drain the watershed before the next storm and the ground is beginning to be soaked increasing the amount of runoff.   September is a month of transition from summer into fall.  Occasionally, early autumn storms can arrive.  This year has been unusually stormy so far and is making things difficult for the project.  It is a little ironic that this project should prevent any future flooding on North  Main Avenue but is being delayed by a flooded worksite.
