Stationing discrepancies are listed in the following table and are depicted on the following page. Please note, Construction Plan and As -built stationing are consistent. The discrepancy between the Detailed Restoration Plan and Construction Plans are not certain, but likely result from easement boundary changes between Detailed Plan figure development and Construction Plan preparation, GIS conversion errors, and/or typographical error. These problems are being resolve for future submissions. The final Asbuilt stationing matches the Construction Plans and depict what was constructed/enhanced at the Site. The original SMU total calculated for the Detailed Restoration Plan was 3006 SMUs. The Asbuilt SMU total calculated for the Asbuilt Construction Plans and Baseline document is 3058 SMUs.
