The City selected the Track 1 compliance method as the preferred means to comply with the Board’s Trash Amendment Resolution. As such, the City will install, operate and maintain State-Certified Full Capture Systems (FCS) for capturing trash from storm drain pipes and drains from Priority Land Uses such as commercial, industrial and high density residential uses. A trash FCS is defined as a single device (or a series of devices) that traps all particles that are 5 mm or greater, and has a treatment capacity that is either not less than the peak flow rate resulting from a one-year, one-hour storm in the subdrainage area, or appropriately sized to carry at least the same flow as the corresponding storm drain.
The design of the FCS will be based on the use of Continuous Deflective Separator (CDS) units at storm drain outfalls and drain inlet filters for catch basins and grate inlets. CDS units capture a very wide range of organic and in-organic solids and pollutants such as total suspended solids (TSS) and other sedimentitious materials, oils and greases, trash, and other debris, including floatables, neutrally buoyant, and negatively buoyant debris. The CDS unit is a non-mechanical self-operating system that functions any time that there is flow in the storm drainage system.
LEE + RO’s scope of services includes project management, performing site investigations with the City, attending design review meetings, preparing a preliminary technical memorandum complete with assessments and recommendations that will serve as the basis of design for preparing 60% design documents followed by final bid documents (plans, specs and estimates).
