Thank you very much for coming by to review the changes in the subdrain for.the Leona Quarry project that I had questions about.
Yesterday after the large rainstorm we had a torrential flood the like of. which neighbors had never seen before, even after a multi-day storm.
This flash flood broke the hanging sewer line once again spilling raw sewage into creek, caused the manhole at the bottom of Chimes Creek to overflow again spilling raw sewage into creek, and caused a significant amount of erosion on my property as well as the property of other neighbors.
I understand that this large increase in runoff was due to the City recently allowing DeSilva to redirect much of the drainage from the Ridgemont development as well as the sub drains for the entire western half of Leona Quarry FROM THE DETENTION POND DIRECTLY INTO CITY STORM DRAINS and subsequently into Chimes Creek.
This decision of the City to allow DeSilva to bypass the detention pond with a significant amount of the site's run off has had disasterous results to the Chimes Creek community as documented in Photographs that I gave to you.
I understand that the reason for this temporary measure was because the detention pond/ baker tank system was repeatedly being overwhelmed during rainstorms and could not adequately handle the amount of water coming off the site.
As I’m sure you are aware there are significant fines associated with the City allowing sewer lines to spill into Creeks and waterways and the number of sewer spills is adding up.
I am really quite shocked and disappointed to learn that the City has knowingly greatly increased the rate of run off coming into Chimes Creek after all we have been through so far.
Thank you for taking the time to explain the situation to me. The increased run off now, unfortunately, makes perfect sense to me.
