02540_EROSION_CONTROL.pdf

This document is a technical specification section (02540) for Erosion Control for the Bridgeport WPCA (Water Pollution Control Authority) project, detailing comprehensive requirements for managing soil erosion and sediment control during construction activities. The specification covers three primary parts: General (project conditions), Products (materials), and Execution (installation methods), with specific instructions for implementing erosion control measures including hay bale barriers, filter fabric fences, construction entrances, and temporary mulching techniques.

The specification provides detailed technical requirements for materials such as hay bales (40-120 lbs weight, bound with wire/nylon twine), filter fabric (with minimum 75% filtering efficiency), and temporary mulch (2.5 tons per acre application rate). Key implementation requirements include installing erosion control measures prior to site disturbance, maintaining barriers throughout construction, using specific placement techniques for hay bales and filter fences, and ensuring sediment is retained within contract limits. The document emphasizes periodic inspection, maintenance, and replacement of erosion control elements, with specific guidelines for slope protection, sediment removal, and restoration of disturbed areas.
