About this file

Written by GovTribe AI · Apr 9, 2026

This document is a solicitation for design plans and specifications for flood control channel repairs in Alameda County, California under the Public Law 84-99 (PL 84-99) program. Phase 3 consists of 20 repair sites across three locations: 16 sites on South San Ramon Creek (Line J), 3 sites on Alamo Canal (Line F), and 1 site on Alamo Creek (Site F04). The project is an operations and maintenance initiative to restore damaged flood control channel slopes to their original grades following storm damage from atmospheric rivers occurring between December 2022 and March 2023. Repairs involve excavation of failed slopes, installation of engineered fill with geogrid reinforcement, rock slope protection (RSP) in 1/2-ton and 1/4-ton soil-filled configurations, gravel filters, topsoil cover, hydroseed, and erosion control measures. The typical channel slopes are designed at 2:1 (horizontal:vertical) ratios, with channel heights ranging from 15 to 30 feet.

The contract requires compliance with extensive environmental and regulatory requirements, including biological monitoring by qualified fisheries biologists, California red-legged frog surveys, turbidity monitoring for in-water work, erosion and sediment control best management practices (BMPs), and protection of sensitive habitats. Construction activities below the top of creek banks are restricted to June 15 through October 15 unless otherwise approved. Work cannot be performed on days when the National Weather Service forecasts 0.1 inch or more rainfall in 24 hours. The contractor must establish water quality baselines, manage diversions, maintain public access to trails (requiring detours at specified sites), protect utilities, manage haul routes and staging areas, and restore all disturbed areas to pre-project conditions. The solicitation references standard specifications from Caltrans (2024) and includes detailed typical repair details, site-specific cross-sections, and construction limits of work maps showing ingress/egress routes, staging areas, and access points throughout Alameda County.
