Subject: CT PIPELINE'
Date: November 6, 1997
Hello Paula,
During our Code Meeting on October 30th, we reviewed your memo dated October 17th, 1997.
We noted that the first paragraph states that no impervious surfaces would be created. It is my
understanding that a gravel maintenance road is proposed over the pipeline. This surface would
be considered impermeable. The concern here is that impervious surfaces within a draining
corridor /frequently flooded area could diminish the overall flood storage capacity. It may be
possible to design the CT pipeline with ditch along the side ofthe road to compensate for any
flood storage volume lost. Please provide a memo from a qualified engineer which recommends
design methods which would provide for no net loss in flood storage capacity. Thus approach
would meet the intent of the City's ESA Ordinance. If design modifications are not available, a
floodplain report may be required and alternative mitigation provided per the ESA Ordinance.
Thank you.
