These fixes ensure compliance and keep projects on schedule.
Mistake 1: Incomplete Site Details and Traffic Data
Trigger: Missing lane widths, speed limits, or AADT counts. Fix: Include scaled site plan with dimensions, traffic volumes (from local DOT), and peak-hour data. Safety Network Plans pulls Caltrans TASAS data, adding crash history for high-risk zones.
A Stockton project was rejected twice for vague taper lengths—we added 12:1 ratios per MUTCD Table 6C-3, approved in 5 days. Use LiDAR scans for accuracy; our plans include 1/8-inch precision. Submit 30 days early—Caltrans needs 10–14 business days.
Mistake 2: Non-Compliant Signage and Phasing
Trigger: Undersized signs or missing advance warnings. Fix: Follow MUTCD 6F: 48×48-inch diamonds on highways, 36×36 on local roads. Phase diagrams must show setup, operation, removal. Safety Network Plans sequences signs every 500 feet on freeways.
A Riverside plan failed for omitted “Road Work Ahead” 1,000 feet prior—we inserted G20-1 signs, approved instantly. Include legend with MUTCD codes; our templates auto-populate. Night work requires reflective Type XI sheeting.
Mistake 3: Inadequate Taper and Buffer Calculations
Trigger: Short tapers or no longitudinal buffers. Fix: Use MUTCD Formula: Taper = (W × S) / 60 for merging; minimum 100-foot shifting tapers. Add 50-foot buffers before work areas. Safety Network Plans calculates via spreadsheet, stamping results.
A Fresno ramp closure used 600-foot merging taper (for 60 mph, 12-foot lane)—approved same week. Document formulas in notes; Caltrans loves transparency. Shoulder tapers: L = (W × S²) / 60.
Mistake 4: Missing Pedestrian and Bike Detours
Trigger: No ADA-compliant walkways or bike lane shifts. Fix: Provide 5-foot minimum pedestrian paths with detectable edging. Reroute bikes with signage and barriers. Safety Network Plans adds C30-14 “Bike Detour” signs and channelizers.
An urban Sacramento plan was denied for sidewalk blockage—we inserted covered walkways with handrails, passing in 3 days. Include crosswalk closures with P1-1 alternate routing. Caltrans prioritizes accessibility—non-compliance auto-rejects.
Mistake 5: No Contingency or Emergency Plans
Trigger: Lacking weather, incident, or volume contingency. Fix: Include rain plan (reduce speeds 10 mph, add flaggers), incident response (tow contacts), and high-volume adjustments. Safety Network Plans embeds QR codes linking to live weather feeds.
A Monterey fog-prone site added visibility-based PCMS messages—approved first round. List emergency contacts: CHP, tow, medical. Caltrans requires 24/7 on-call personnel.
Mistake 6: Poor Readability and Formatting
Trigger: Hand-drawn plans, tiny fonts, or cluttered layouts. Fix: Use 11×17 sheets, 12-point Arial, north arrow, scale bar. Safety Network Plans delivers PDF + AutoCAD with layered, color-coded phases.
A hand-sketched plan was returned unread—we redrew in CAD with grid, approved in 7 days. Include title block: project ID, ENC number, revision date. Digital stamps speed e-signatures.
Mistake 7: Ignoring Encroachment Permit Requirements
Trigger: Missing insurance, bonds, or traffic impact studies. Fix: Attach Caltrans Form ENC-1, $1M liability proof, performance bond. Include TIAs for >500 vph impact. Safety Network Plans packages full submissions.
A San Diego contractor forgot bond—30-day delay. We bundle all docs, achieving 95% same-week issuance. Use Caltrans LAPM checklists—our plans pass every item.
