About this file
This is a Request for Survey Data document issued by the San Bernardino County Flood Control District for the Hawker Crawford Channel Project (System #1-806-1B, Work Order F02646). The project involves surveying approximately 4,000 lineal feet of existing trapezoidal channel that will be diverted and reconstructed as a single 20-foot wide by 10-foot high reinforced concrete rectangular open channel, extending from south of Beech Avenue in a southwest direction along the west side of Interstate 15 Freeway, crossing under Cherry Avenue, and connecting to the existing San Sevaine Basin #5. The survey scope includes collecting topographic data on existing roadway centerlines, curbs, gutters, pavement conditions, utilities, drainage structures, and channel features within specified survey limits shown on three attached location maps. Specific survey tasks include collecting invert elevations of the existing Hawker Crawford Channel and storm drain inlets/outlets, surveying existing street manholes and catch basins with depth measurements, collecting data 10 feet behind existing sidewalks, and providing quarter delta elevations at existing ramps and curb returns. The deliverable must be provided in Civil 3D CAD format, with survey data tied to at least two recorded or filed monuments on the same line to establish a basis of bearing.
No specific contract response date, due date, award date, contract term, pricing terms, or other commercial details are indicated in this survey request document. The document was prepared in November 2025 and was requested by Eloy Ruvalcaba from the Flood Control Engineering Design Team B. The related contract opportunity indicates that proposals must be submitted electronically through the County Electronic Procurement Network (ePro) or via hard copy with original signature to a specified address, with the Fee Proposal Sheet submitted separately and clearly labeled.

Specifications and Details:
The Project is to divert the existing trapezoidal channel (mix of earthen and concrete) from its original alignment and turn the channel into a single 20’ W x 10’ H reinforced concrete rectangular open channel from south of Beech Avenue, traveling in a southwest direction along the west side of I-15 Freeway, crossing under Cherry Avenue and outlets to the existing San Sevaine Basin #5. This will include a 10’ W x 10’ H double cell reinforced concrete box culvert to convey the flows beneath Cherry Avenue.
The Project in general consists of constructing approximately 4,000 lineal feet of single reinforced concrete rectangular open channel 20’ W x 10’ H, and related junction structures, transition structures, inlets and outlets, cutoff walls, channel fencing, access ramps, roadway reconstruction and utility relocation. The Project will be designed to accommodate 100-year storm flow events.
General Scope of Work:
• Pick up all topo features as shown on the attached maps but not limited to: existing roadway centerline profile (crown), curb and gutter, ramp, driveways, sidewalks, curb and gutter, cross gutter, edge of pavement, traffic stripes, pavement markings, fences, fence lines, traffic signal poles and signal loops, signal cabinets, guardrails, utilities (electrical, water vault, water meter, power poles to include pole number, fire hydrants, etc.), AC dike, dead man, fire hydrants, road signs, private signs, trees, tree stumps, drainage structure, inlets/outlets, grouted and ungrouted rock, sewer manholes, headwall, top & bottom of slope, flow line, grade breaks, mailbox, paddle, bridge walkway structures, object marker, utility risers and cabinets, and any other objects found not mentioned within the project survey limits. In addition, please perform the following tasks:
1. Collect survey data for the existing invert elevation of the Hawker Crawford Channel and storm drain inlets/outlets. This includes existing channel centerline profile, block walls or retaining walls, wing walls, rails, inlets, top and bottom of slope, chain-link fence and gate, and any other objects found within 200’ as shown on the project survey-limits maps (Sheets 1 and 2 below).
2. Collect survey data for any existing street manholes and catch basins. Dip the manhole and catch basins for depth at the invert.
3. Collect survey data 10’ behind existing sidewalk. No collection is needed beyond existing property walls or fences, if any.
4. Collect quarter delta elevations at existing ramps or returns (curb face and flowlines) and elevations along BCR and ECR.
5. Provide CAD (Civil 3D) format.
NOTES:
1) See attached location maps (1 and 2) for survey limits.
2) Tie into at least two monuments on the same line and shown on a recorded or filed map for a basis of bearing.
Should you have any questions, please call me at the above number. Thank you.
