Canyon Lake USACE Permit & Analysis

I must file a complete US Army Corps of Engineers (USACE) permit application to confirm—or, if required, modify—existing improvements that sit inside the flowage easement on my Canyon Lake, Texas property. The items that need review include retaining walls, patios, stairs, landscaping, as well as buildings, fences, utilities, and any other structures currently on-site.

To support the submittal, I will share a recent property survey/site plan. Your task is to overlay that information with historical and current satellite imagery and topographic data, then pinpoint where today’s conditions differ from the past. The end goal is clear: show which improvements must be removed or changed so the Corps can approve what remains.

Core deliverables
• Annotated aerial/topographic exhibits comparing past vs. present conditions
• A concise findings memo identifying every improvement that triggers USACE action, with recommended changes or removals
• All drawings, shapefiles, or CAD files created during the analysis
• A ready-to-file USACE permit package, including the above exhibits and any required application forms

Acceptance criteria: exhibits must reference imagery dates, tie directly to survey coordinates, and clearly label each improvement’s status (retain, modify, or remove). The package should follow current USACE Fort Worth District guidelines and be PDF-ready for digital submission.

GIS, Google Earth Pro, AutoCAD, or similar tools are expected for accuracy. Please indicate your experience with USACE permitting or comparable regulatory filings when you respond.
