DISCUSSION
The Slack Water Tank uses an array of instrumentation to control when and how much water is
allowed to flow into the tank. Occasionally, this instrumentation fails and water is allowed to
flow into the tank when it is already full. The overflow line exists to allow an emergency exit for
this water to escape before it can damage the tank. Currently the Slack Water Tank Overflow
line spills its flow onto an unimproved access road. The water then flows down this access road
collecting native soils and aggregate. Eventually this flow reaches Paso Robles Street were the
water drops the native soils and aggregate creating a. nuisance for surrounding property owners
and a maintenance problem for City staff. .
This project will install a new 310mm overflow line from the water tank, approximately 138
meters to the paved portion of Paso Robles Street.

A Notice of Exemption has been filed with the City's Community Development Department.

Dear Council Members:
Please support item C-8 (Slack Street Water Tank Overflow).
Prior to the recent diversion of overflow from this tank to the access road it would come straight down the
hill onto Slack Street. From there it would travel down the first two driveways through the backyards,
turning everything into a mucky mess and then
finally exit on Hays Street. This has happened countless times in the 30 years I have lived on Hays Street.
Since it probably will overflow again it seems most prudent to extend the overflow line to a point where the
water can reach the storm drain in a direct.manner.
Cheers,
Cydney Holcomb
2076 Hays Street
