📢 Boulder Sign & Foundation Wind Certification

✅ Structural Letter for Wall-Mounted or Freestanding Signs (City & County Approved)

This engineer-stamped wind load certification ensures your proposed sign meets Boulder’s high wind zone requirements — especially critical for projecting signs, monument signage, or wall-mounted signs with structural attachments.

The City of Boulder requires structural engineering for signs that project into public ROW, exceed certain heights, or include foundation systems. Boulder County similarly enforces wind load and anchorage compliance.

🧾 What’s Included:

✔️ PE-Sealed Structural Letter (Colorado Licensed)

✔️ Wind Pressure Calc for Sign Area & Height

✔️ Wall-Mounted Attachment Verification (bracket anchorage)

✔️ Freestanding Sign Foundation Design (monument or pylon style)

✔️ Exposure & Topographic Factors Considered

✔️ Permit-Ready PDF Format

🌿 Use Cases:

Retail Business Signs (Shopping Centers, Multi-Tenant)

Freestanding Monument or Pylon Signs

Projecting Blade Signs on Urban Facades

Commercial Real Estate or Office Park Signage

Wall-Mounted Channel Letter Signs

💬 FAQs:

Is engineering always required for signs in Boulder?

Not always — but if the sign is tall, projecting, mounted high, or freestanding, most building departments will request engineering.

Do you include a stamped foundation drawing?

Yes — for freestanding or monument signs, we include a sealed footing layout to resist uplift and overturning.

What if my sign projects over the sidewalk?

The City may require a revocable ROW permit. We’ll provide the wind calc and attachment letter to support your application.

Can you calculate multiple sign types in one order?

Yes — just let us know how many signs and which types. We’ll confirm scope and combine where feasible.
