Newport Beach's Harbor Litter Removal Project

Project Location:

Bayside Drive/Carnation Ave and Bayside Drive/Heliotrope Ave in Newport Beach, California

Project Description:

The City of Newport Beach has an aggressive program to prevent tons of trash and debris from entering Newport Bay through the its storm drain system.  Public Works installed two hydrodynamic separation units (a Contech Continuous Deflective Separation (CDS) unit and a Bio Clean Nutrient Separating Baffle Box (NSBB) unit). These units will remove tons of trash and debris from Newport Bay each year.  Trash in Newport Bay causes significant water quality problems. Small and large floatables can inhibit the growth of aquatic vegetation, decreasing spawning areas and habitats for fish and other living organisms. Wildlife can be harmed by ingesting or becoming entangled in floating trash. Floating debris that is not trapped and removed will eventually end up on the beach or in the open ocean, repelling visitors away from our beaches and degrading coastal waters. Settleables include glass, cigarette butts, rubber, construction debris and more. Settleables can be a problem for bottom feeders and can contribute to sediment contamination. Some debris (e.g. diapers, medical and household waste, and chemicals) is a source of bacteria and toxic substances. Trash continues to impact beneficial uses.
CDS is a swirl concentrator and screening system that captures 100% of the floatable trash and debris.  CDS retains all captured pollutants, even at high flow rates, and provides easy access for maintenance.  The precast concrete cylinder structure has a10 feet diameter and stands 18 feet high.  The CDS unit has sediment storage volume of 234 cubic feet.
The Bio Clean Environmental NSBB is a unique hydrodynamic separator that is effective at capturing trash and debris, organics, and gross solids in a raised screening basket which allows these pollutants to be stored in a dry state.  Storing these pollutants in a dry state eliminates nutrient leaching, bad odors, higher BOD, bacteria growth, and septic conditions. The precast concrete structure is 25 feet long 12 feet wide and 13 feet high.  The sediment storage holds up to 1169 cubic feet and the screen capacity of 270 cubic feet.

Project Justification:

This project stands out because it utilizes Orange County Transportation Authority (OCTA) funding and a successful partnership with OCTA and the community to remove pollution from a large drainage area and storm drain system that flows into Lower Newport Bay.

Special Circumstances:

The City of Newport Beach enhanced their relationship with OCTA and the community by successfully applying for grant funding and delivering the project on schedule.
