I will prepare a no rise study using hecras for floodway permit

Are you Working in a regulatory floodway and need to show your project won't raise flood elevations? I build HEC-RAS models to support No-Rise Certifications, so you can move forward with your floodway permit without triggering a FEMA CLOMR.

What you get:

• Existing (pre-project) HEC-RAS model, built from effective FEMA flood study data (FIS, FIRM, HEC-RAS/HEC-2 model where available)
• Proposed (post-project) model reflecting your grading, fill, structures, or floodway encroachment
• Water surface elevation comparison at each cross-section for the base flood (1%-annual-chance) event
• Confirmation of no-rise compliance (typically 0.00 ft, per 44 CFR 60.3(d)(3); I'll confirm your local tolerance)
• Cross-section and profile exhibits, existing vs. proposed
• Summary table of WSE differences by cross-section
• Draft No-Rise Certification letter for your floodplain administrator or PE to review and seal
• Supporting GIS mapping of the floodway relative to your site

Note: I build and run the model and prepare the documentation. Certification must be sealed by a licensed PE. I'll flag any jurisdiction-specific requirements before submission.
