About this file

Written by GovTribe AI ·

This attachment document provides structural best management practices (BMPs) examples for the John Wayne Airport Maintenance Building located at 3160 Airway Avenue in Costa Mesa, California, prepared by Orange County. The document contains photographic examples and technical specifications for stormwater treatment and filtration systems installed at the facility, including driveway trench drains with Kristar LoPro filters, permeable pavers in five parking areas, a modular wetland system with plantings, flat-grated storm drain inlets with FloGard filter inserts, five curb inlet catch basins with FloGard Plus filter inserts, and a loading dock sump and pump system. The attachment serves as a reference guide for the inspection and maintenance contract opportunity, demonstrating the specific equipment and infrastructure that will require ongoing maintenance services.

The document includes comprehensive technical specifications and capacity data for FloGard stormwater inlet filtration products in multiple configurations, including catch basin inserts, flat-grated inlets, circular grated inlets, and trench drain filters. Specifications detail solids storage capacity, filtered flow rates, total bypass capacity, and dimensional information for various model sizes ranging from compact 12-inch units to large 48-inch configurations. The trench drain filter section specifies both pipe and panel alternatives with varying widths from 3.0 to 24.0 inches and includes maintenance guidance indicating that loading dock sumps may accumulate sediment and trash requiring semi-annual cleaning. This technical reference material establishes the baseline equipment and performance standards that the Stormwater Treatment Units Inspection and Maintenance contractor will be responsible for monitoring and servicing.

Trench Drain Filter

The FloGard Trench Drain Filter is a modular filter designed to collect sediment, debris and petroleum hydrocarbons from stormwater runoff into trench drain systems. It includes a UV-resistant woven geo-textile wrapped around a perforated core encapsulating a sorbent material which is easily replaced, providing for flexibility, ease of maintenance and economy.

For narrow and constricted areas often found in trench drains, the FloGard Trench Drain Filter provides an effective solution to comply with stormwater runoff issues. The units perform as an effective filtering device at low (“first flush”) flows, and because of the built-in high-flow bypass, they will not impede the drainage system’s maximum design flow.

FloGard Trench Drain Filters are available in sizes to fit most common trench drains. Contact Oldcastle Infrastructure for additional sizes and project specific details.
