<br />7.A <br />Page 39 <br /> <br />. Deep tunnel but with Caltrain in covered trench or at grade with grade <br />separations as needed (road under preferred) <br />. HSR in tube/trench with Caltrain in trench, stacked <br /> <br />Group 4 - other combinations to study <br />. Everything in tunnel except at Redwood Junction <br />. Aerial tracks with sound reflector and close privacy shield <br /> <br />Group 5 - other combinations to study <br />. Stacked track, cut and cover <br />. Buildings to span across right of way <br />. For option 3 as shoV\7l1 on matrix (open trench), cut and cover so only a <br />portion is open <br />. Park and bike boulevard over the top if covered <br />. Use some land for mixed use near station and housing between stations <br /> <br />Group 6 - other combinations to study <br />. Aerial for HSR, at-grade for Caltrain <br />. Aerial with a bubble/ baffle to reduce noise <br />. New route <br />o Along the Bay <br />. Why do we have to stick with present Caltrain route? <br />. Is it possible to have a one-track shoo-fly? <br />. What about 280 highway route? <br />. 2 tracks above, 2 tracks below (2 tracks aerial, 2 tracks at-grade) <br />. Right of way not wi.th Caltrain right of way <br />. Covered aerial with translucent glass to keep sound/noise from reverberating <br />through neighborhoods <br />. Hat Trench concept. Tunnel with hat-trench above. <br /> <br />4. Based on the options presented what would be your preferences? <br />. Green sticky dot: your preferred option <br />. Yellow sticky dot: your 2"d choice <br />. Red sticky dot: least favorite option <br /> <br />See 8th" x 14" sheets from each group <br /> <br />Additional Input <br /> <br />A workshop attendee sent a follow-up em.ail requesting that the HSR Authority take another <br />look at the 101/Altamont option, as it will be less expensive and much less invasive to residents <br />and businesses. <br />
