Figure ES-5 shows all o the possible LRT routes and stations identifed orstudy in the Drat EIS/EIR. The eatures and impacts o each o the buildalternatives are described in the ollowing section.
At-Grade Emphasis LRT Alternative
The At-Grade Emphasis LRT Alternative would provide a direct connectionrom the existing underground 7
Street/Metro Center Station to the MetroGold Line at Temple and Alameda Streets with three new station locations.This alignment includes a combination o underground and at-gradesegments, with 46 percent o the route underground. New stations wouldserve the Civic Center, Grand Avenue, and the Financial District. 2
Streetwould be converted to a pedestrian-riendly transit mall between Hill and LosAngeles Streets. To implement this alternative, the number o trafc lanes andon-street parking spaces would be reduced on 2
Street. As a result, trafcis likely to divert to adjacent parallel streets such as 1
Streets, butthe roadway capacity along these streets would remain unchanged. Roadwaycongestion would likely increase along these streets. Figure ES-6 provides anillustration o a typical at-grade alignment.

Underground Emphasis LRT Alternative
The Underground Emphasis LRT Alternative would provide a direct connectionrom 7
Street/Metro Center Station to the Metro Gold Line tracks at the LittleTokyo/Arts District Station with three new station locations. The alignmentwould extend underground rom the 7
Street/Metro Center Station underFlower Street to 2
Street. The tracks would then proceed east underneaththe 2
Street Tunnel and 2
Street to a new portal on the parcel bounded by1
Street, Alameda Street, 2
Street, and Central Avenue. It is anticipated thatsome o this parcel would need to be acquired to construct the portal andstage construction o the tunnels beneath 2
Street. The new tracks wouldthen connect to the tracks o the Metro Gold Line at-grade. The UndergroundEmphasis LRT Alternative would be located entirely underground except or asingle at-grade crossing at the intersection o 1
and Alameda Streets. FigureES-7 is an illustration o a typical underground alignment.
Fully Underground LRT Alternative
As a result o a unique and intense community engagement process thatevolved rom the scoping process, the Fully Underground LRT Alternativewas developed to best address community concerns simultaneous withcost, operational, and design considerations. Based on this extensive publicoutreach eort, Metro sta recommended that the Fully Underground LRTAlternative be designated the sta-recommended LPA in the Drat EIS/EIR.This recommendation was made by Metro sta because this alternativeuniquely addresses community concerns, and the Regional Connector’stransportation purpose and need.The Fully Underground LRT Alternative in the Drat EIS/EIR is essentially thesame confguration as the Underground Emphasis LRT Alternative, except thatit provides or our new underground stations instead o three, and it traversesunder the intersection o 1
and Alameda Streets connecting to the MetroGold Line within 1
Street and north o Temple Street.The alignment would extend underground rom the 7
Street/Metro CenterStation under Flower Street and 2
Street to Central Avenue in the samemanner as the Underground Emphasis LRT Alternative. At 2
Street andCentral Avenue, the tracks would continue underground heading northeastunder 1
and Alameda Streets.An underground junction would be constructed beneath the intersection o 1
Street and Alameda Street. To the north and east o the junction, trains wouldrise to the surace through two new portals to connect to the Metro Gold Lineheading north to Montclair and east towards I-605.
Figure ES-8 is an illustration o a typical underground station, and Figure ES-9is a typical underground station entrance as seen rom street level.Figure ES-10 shows the existing Metro Rail system without the RegionalConnector. Figure ES-11 shows how the system would operate with the LPAillustrating the enhanced connectivity, new stations, and reduction in transersassociated with this alternative.
