About this file

Written by GovTribe AI ·

This is a location map document prepared by the San Bernardino County Flood Control District for the Birch Creek Cutoff Walls project located in the Oak Glen Area, Zone 3, east of Oak Glen Road in California. The map illustrates the proposed cutoff wall construction extending approximately 0.53 miles from Oak Glen Road along Birch Creek. The project involves replacing an existing earthen trapezoidal channel with a proposed 14-ton concreted rock slope cutoff wall, with a typical section showing dimensions of 36 feet wide at the top, 12 feet wide at the base, 8 feet in height, with 4-foot and 6-foot side slopes. The map identifies four curved sections within the project alignment, with stationing and geometric data including curve radii ranging from 571.21 to 1,400 feet, tangent lengths, and arc lengths for each curve segment. The project area encompasses right-of-way along Yucaipa Ridge Truck Trail, Potato Canyon Road, Briarcrest Drive, and Birch Creek Lane, with elevation contours ranging from 4,200 to 4,490 feet.

The drawing documentation, dated April 21, 2025, was prepared under File No. F02941 by the San Bernardino County Flood Control District, with engineering personnel identified as Lawrence G. White (Project Engineer), Eloy Ruvalcaba (Recommended By), and Mervat Mikhail (Flood Control Engineer). The associated RFP for Environmental Permitting of this Water Infrastructure Project has a deadline for questions set at 3:00 p.m. on September 23, 2026. This location map serves as a key reference document for bidders responding to the environmental permitting contract opportunity and provides the spatial context necessary for understanding the project scope and construction parameters.
