Next briefing: We’re at Seattle Center’s Center House, where the next sheaf of data in the search for the Alaskan Way Viaduct Central Waterfront solution is being released. One quick topline: The costliest in terms of time and money would be Scenario F, the “bored tunnel” — up to 9 and a half years of construction time, $3.5 billion cost. The numbers here are all described as “capital costs” — so that’s just the basic building costs for the “Highway 99 corridor” itself, not including additional components in the complete study area (which includes downtown) such as changes to I-5, changes to traffic, etc. Other “capital” dollar figures: Scenario A, “demand management/low capital,” $800 million; B, “surface boulevard,” $800 million; C, “surface couplet,” $900 million; D, “independent elevated,” $1.6 billion (shown in WSDOT rendering above); H, “lidded trench,” $1.9 billion; E, “integrated elevated,” $2.2 billion; G, “cut and cover tunnel,” $2.7 billion. The handouts here also break out the major components in terms of cost — relevant because the government leaders working on this have said that the three “finalist” options to be determined within a few weeks likely will be composites with elements of the current “scenarios,” rather than including any existing scenarios exactly as they have been considered up till now. WSDOT’s Ron Paananen stresses, these are “rough estimates.” ADDED 12:57 PM: Our previous links to briefing materials have vanished into the wireless ozone, so here they are again: For starters, all eight “scenarios” — pieces of which will be cobbled into the eventual “finalists” — have a new set of graphics that you can see by going to this Flickr collection set up by WSDOT. The handout with the full range of cost possibilities can be seen here; the handout with the full range of construction-time possibilities can be seen here. Later today, the Stakeholders’ Advisory Committee will be briefed on this information, 4 pm, Plymouth Congregational Church (downtown). The city and state officials who have been leading these briefings stressed again today, they are still on schedule for state/city/county leaders to arrive at a final recommended solution by year’s end. One interesting note from the briefing: SDOT’s Bob Powers said they’re realizing as they evaluate data that, regarding transit, “if we build it, the riders will come” – so there is a suggestion that before major construction starts, transit additions be made, including a second West Seattle RapidRide Metro bus route along Delridge (that previously was suggested as something that could be considered in the long run). ADDED THURSDAY EVENING: A downtown public forum is set for people to speak out on whatever the final options are revealed to be: 5-7:30 pm December 15, Town Hall (1119 8th, downtown). Also – all materials presented at today’s briefing, plus additional information unveiled at the Stakeholders Advisory Committee meeting later in the day, is now posted on the Viaduct website – look here, under November 20 meeting materials.
