How much open/ how much closed <br />. Concern that this does not change or interfere with Redwood City <br />o We want what is best for our city <br /> <br />3. What other combinations would you like to be studied? <br /> <br />Group 1 - other combinations to study <br />. Stacking in covered trench <br />. Hybrid low berm <br /> <br />Group 2 - other combinations to study <br />. Double track cut/cover box <br />o Double track in tunnel (deep tunnel is best option) <br />o Sheet #11 of 24 on combination draft typical sections HSRA document <br />of 3/24/10 ' <br />. 67' right of way <br />
