The primary purpose of this meeting is to achieve Merger Project Team Concurrence on Points 2A (Bridging and Alignment Review) and 4A (Avoidance and Minimization) for the proposed I-40/I-77 Interchange Improvements. Background The Initial Merger 01 Screening Meeting for the proposed project was held on March 17, 2004, and it was determined that the project would follow a modified process. After a Jurisdictional Determination field meeting on March 29, 2005, the USACE suggested that, due to the amount of jurisdictional features potentially impacted by the project and the higher quality characteristics associated with several systems present, the project would be returned to the Merger 01 Process at CP 1. After an agency coordination meeting on April 14, 2005, NCDOT received a letter from USACE addressing their change in position that the project enter the Merger 01 process at CP 1. An agency coordination meeting was held between NCDOT, FHWA and USACE on September 27, 2006 to present the project alternatives carried forward, explain the alternatives that did meet the purpose and need, and quantify the impacts to the natural and human environments. Based on this presentation, USACE agreed that it would be acceptable to proceed with the project as originally agreed upon as long as NCDOT held a coordination meeting with the other Merger Team members to solicit comments before the circulation of the Environmental Assessment (EA). An agency coordination meeting was held on October 17, 2006 to present the project to the Merger Team members and solicit input. The EA was approved on November 29, 2006. Project Description The proposed action is designated in the latest approved NCDOT's Transportation Improvement Program (TIP) as TIP project number I-3819 and is described as "Statesville, modification of I-40/I-77 interchange area." The primary needs for the proposed action include the following: • Traffic capacity deficiencies; Existing safety concerns; • Diminished ability to function as a North Carolina Strategic Highway Corridor; and, • Diminished ability to function as a part of the United States Interstate System. The primary purposes for the proposed action include the following: • Improve traffic flow along the I-40 and I-77 corridors within the study area; and, • Improve regional connectivity between Iredell County and points, east, west, north and south within North Carolina and across the Interstate System. A range of alternatives for the proposed action were evaluated including the No-Build Alternative, Transportation System Management (TSM) Alternative, Mass Transit Alternative, wetland avoidance alternatives, and several build alternatives. Based on an evaluation of the alternatives and the purpose and need for the project all but two build alternatives were eliminated from further study. The two build alternatives that were carried forward were designated as detailed construction alternatives and referred to as the Four-level Offset Interchange Alternative and the Four-level Turbine Interchange Alternative. Based on data gathered and presented in the EA, on April 26, 2006 the NCDOT selected the Four-level Offset Interchange Alternative as their Recommended Alternative. The overall effects for both detailed construction alternatives are very similar. The primary reasons for the selection of the Four-level Offset Interchange Alternative were lower wetland impacts and a more desirable geometry with flatter curve radii for the directional ramp movements. Design Revisions Final design has begun and has been completed to the 25% design phase. Concerns related to flooding on I-40 resulted in detailed analysis of floodplain impacts. As a result, the elevation of I-40 was raised to provide for passage of the 100-year storm. Summary of Agency Comments See "Agency Comments" tab for summary of agency comments. Summary of Public Involvement Comments See "Public Involvement" tab for post-hearing meeting minutes. Avoidance and Minimization Due to the extent of wetlands and streams within the project study area, and the location of the existing roadways and interchanges, avoidance is not possible. Minimization for wetlands includes the examination of appropriate and practicable steps to reduce adverse impacts to wetlands. In order to minimize the impacts to wetland W15, which has the highest NCDWQ wetland rating (92) in the natural resources study area, the bridge proposed to span Fourth Creek for each alternative is being lengthened beyond what is needed hydraulically and will span an additional length of this wetland area that would have been impacted by roadway fill. Minimization of streams includes the examination of appropriate and practicable steps to reduce adverse impacts to streams. A retaining wall is proposed to run adjacent to the east side of I-77 for 1,730 feet to keep the fill slope from impacting stream S3. Other steps that will be implemented to minimize impacts to wetlands and streams include: • Minimizing "in-stream" activities, • Strictly enforcing the sedimentation and erosion control best management practices (BMPs) for the protection of wetlands and streams, • Decreasing the impacts of the project through the use of Type III clearing and grubbing which does not clear the entire right of way width, • Decreasing the footprint of the project through the steepening of fill slope where possible, and Utilizing natural stream channel design principles when relocating streams. Summary of Impacts The summary of impacts is included in Table 1. The impacts in the Environmental Assessment were based on 10 feet beyond the slope stake limits. Current NCDOT guidance calls for the impacts for preliminary design to be based on a 25-foot buffer from the slope stake limits. Because of this some of the impacts have changed.
