Site work for a water / sewer project in Portsmouth, Virginia. Conceptual plans call for site work for a water / sewer project.

The Stormwater Outfall Upgrade Project aims to rehabilitate and modernize deteriorating stormwater outfall infrastructure at critical discharge points within the municipal stormwater system. The project focuses on improving the points where drainage facilities discharge into receiving channels or bodies of water. Several key outfall structures currently exhibit significant deterioration, erosion damage, and inadequate capacity to handle increasing storm intensities. The scope of work includes: 1. Structural Rehabilitation: Replace compromised pipes, headwalls, wing walls, and aprons at each outfall location. Install reinforced concrete structures designed to current engineering standards. 2. Upsizing Infrastructure: Increase pipe dimensions at outfalls to accommodate higher flow volumes from more intense storm events, considering future climate change impacts. 3. Erosion Control Measures: Implement energy dissipation structures including stilling basins, stone aprons, and engineered step pools to reduce discharge velocities and prevent downstream channel erosion. 4. Sediment Management: Create sediment forebays to capture and facilitate the removal of suspended solids and associated pollutants before discharge into receiving waters. 5. Channel Improvements: Conduct strategic channel excavation and stabilization to improve flow conveyance and prevent undercutting of outfall structures. 6. Environmental Enhancements: Install trash capture devices and implement naturalized design elements where appropriate to improve discharge water quality. 7. Monitoring Systems: Implement flow monitoring instrumentation at critical outfalls to provide data for the municipal stormwater management system. 8. Site Restoration: Restore disturbed areas with native vegetation and stabilization measures, improving both function and aesthetics at outfall locations.
