Attachments: message.wav; master storm 1977_20150814_0007.pdf; Hi Ken, I received a phone message today with concerns the added impervious surface, including the added drainage, would increase flooding issues at the apartment properties to the north of Heintz St. The storm line he is referencing can be seen on sheet PP02 and runs north through their property to Toliver. It appears the line is a 24” concrete pipe. Dan Zinder just recently found maps of the system that was originally installed in 1977, I attach a copy of the sheet that applies here. In the design we increased the size of the storm line to 30” to accommodate for additional storm during a storm surge followed by a 12” storm line for flow control. I also see in the Stormwater report the Summary states, “the post construction flows are equal or less than the pre-construction flows”. I will return the call and pass on the information. I just wanted to keep you in the loop.
