Final Environmental Assessment
I-66-ITB-Widening-EA_Cover_ALL.pdf 1 11/4/16 10:33 AM ERRATA NOTICE Following the November 18, 2016 publication of the Environmental Assessment (EA) for the Transform Interstate 66: Inside the Capital Beltway, Eastbound Widening project, an additional new noise barrier was identified to be preliminarily feasible and reasonable for Common Noise Environment (CNE) P, which is just east of North Sycamore Street. This additional new noise barrier was not previously identified in the Preliminary Noise Analysis (VDOT, 2016g). As a result, the project limits of disturbance (LOD) have been revised to include this additional new noise barrier area and the following technical corrections to the EA, tabulated below, are necessitated. The location of the expanded LOD area associated with the additional new noise barrier is shown in the figure that accompanies this errata notice. These changes, and any others that may be required in response to comments received during the public comment period, will be reflected in a revised EA that the Virginia Department of Transportation will furnish to the Federal Highway Administration prior to requesting a decision to be made under the National Environmental Policy Act of 1969 (NEPA). Summary of Technical Corrections Page Location Correction The reported total length of noise barrier preliminarily identified as needing to be Table 3-1, Row replaced, and feasible and reasonable to attenuate for noise impacts is 19,490 3-32 9 linear feet. A total of 512 receptor units are anticipated to be benefited and the barrier cost is assumed to be approximately $7.2 million. Table 3-2, Row The total area for the Build Alternative noise barriers is 11.5 acres and the total 3-34 1 LOD is 54 acres.
