9/3/2011 7:00 AM 0.00 0.0 M M M power restored 8:02PM - 142 hours (almost 6 days) The Rockaway River and Denbrook have receded but the low lying areas are devistated. A good number of downtown shops had severe flooding and the dammage is incredable. Some families lost their homes, foundations buckled and homes collapsed into the river. We got free dinners at town hall, a $5 water voucher from the state and 12 leters of free water packed for 5 year storage just appeared on our doorstep (on the 6th day). Our street lost power early in the storm probably due to a downed tree. There were at least 6 mature oak trees that had fallen over the road in a one mile spread. Neighbors went up and down the street with chain saws cutting logs and putting them on the side of the road.Some of the people also used leaf blowers to clean the smaller debris. Cable and telephone wires were down in places including to our house.We had 2 big treelimbs break off at the back end of the storm and some smaller trees were broken toward the back of our property. I back olgged data to the storm.
