In the past, the open air bioswale along the easterly side of Newport Boulevard
southerly of 15th Street was routinely covered by debris from heavy storm flows. The
extent of litter would at times also clog the storm drain outlet pipe causing localized
flooding on northbound Newport Boulevard. These events caused extra work for City
field crews and traffic interruptions for the traveling public.
As such, staff applied for and secured Measure -M grant funding from the Orange
County Transportation Authority (OCTA) to offset the cost of installing two Continuous
Deflection Separator (CDS) trash and debris interceptors to proactively trap and remove
drainage flow debris. One CDS was installed in the ground next to the Municipal
Operations Corporation Yard transfer station. The other unit was installed in the
easterly slope of Newport Boulevard just south of 15`h Street. These units will not only
capture the street litter before reaching the Newport Boulevard bioswale, but will also
improve water quality in the Bay and minimize Newport Boulevard traffic flow
interruptions during heavy storms.
The contract has now been completed to the satisfaction of the Public Works
Department.

The final contract cost was 11.3 percent above the original contract amount. This extra
contract cost was due to the substantial unforeseen field conditions encountered during
construction including soil stability issues, buried debris and unknown underground
water flows that required additional foundation and site work to install the unit.
A summary of the project schedule is as follows
Estimated Completion Date per July 2012 Baseline Schedule: November 21, 2012
Project Awarded for Construction: June 12, 2012
Number of Additional Approved Work Days: 29
Completion Date from Award with Approved Extensions: January 29, 2013
Actual Substantial Construction Completion Date: January 8, 2013

Regulations, Title 14, Chapter 3, because it has no potential to have a significant effect
on the environment.
