The project involves the construction and operation of a new 14.5-mile light rail transit line. Based on agency and public input received during the environmental review process, changes to the project were considered and carried forward as part of the project design. For example, a new design option to close 186^th Street instead of closing 187^th Street was identified during stakeholder coordination after circulation of the Draft EIS/EIR in order to both minimize the number of at-grade crossings along the alignment and take into consideration community input into where permanent road closures were most appropriate. The design option was evaluated in the Final EIS/EIR, and was incorporated into the Locally Preferred Alternative, which has resulted in a safety benefit for the surrounding community. Additionally, in response to comments from property owners and a freight rail operator, the project design was refined to avoid a full acquisition of a property, which avoided impacts to businesses. Furthermore, the location of a traction power substation was changed to avoid a planned bike trail extension, which avoided conflicts with the planned recreational amenity for the community. The project design was also refined as a result of agency comments to change the Artesia Station parking structure access points and signalize the intersection, which will facilitate vehicle circulation and safety.  Another modification was the inclusion of vertical screening elements where aerial structures would be situated adjacent to the rear of residential properties, which was a measure identified to address privacy concerns raised in public comments.
