Correction: the extremely turbid water released into Chimes Creek was 480 NTU, not 700-800 NTU as previously stated below.

Chimes Creek is opaque with silt again after this last storm. According to City inspector the detention pond is overflowing this morning and overflowed this past Sunday releasing extremely turbid water (in the 700-800 NTU range) into Chimes Creek.

Is this now acceptable?

The sanitary sewer manhole on Oakdale ave that we keep telling the City about is spewing raw sewage into the Creek. This is the same line that will take on the additional 470 households being built in the development.

Over a cubic yard of my property collapsed into the creek from this latest flash flood from the quarry. I have never seen erosion like this here even in much worse storms.  The contractors seem to be pumping water from the Quarry night and day and still the pond overflows whenever it rains.

Nobody in the community as far as I know has heard anything from DeSilva Gates regarding damage from the last release. (From David Lau's email: "We have directed DSG to make contacts with the private property owners.")

And we still have yet to hear the rationale that the City used when issuing a Category II Creek Permit for work that included a large amount of earthwork within 100 feet of Chimes Creek.

Please respond to these issues as the community is very upset and concerned about future storms.
Thank you,
