The Bend City Council convened for a work session to review informational updates on major infrastructure projects and to initiate a strategic discussion regarding a Public-Private Partnership (P3) for a future City Hall. Key topics included conceptual designs for the Hawthorne Overcrossing and Reed Market Bridge, a legal briefing on federal grant conditions, and a deep dive into financial feasibility and land use strategies for potential mixed-use city hall development.
Hawthorne Overcrossing Bridge
Reed Market Bridge
City Hall P3 Analysis & Future Development
Good afternoon, everybody. We will go ahead and start our Bend City Council work session for today. Um let's start with roll call. You're in uh councillor Plack. Steve Platter, he here. Megan Morris, she here. Megan Perkins, she her. Helene Kibo, she her. Mike Riley, he him. Ariel Mendez, he him. Tina Franz is that she here. All right, we're gonna start off with um update informational about our bridges. So we'll kick it over to you guys. All right, thank you. So in about a half an hour here, we're gonna quickly go through an update for the Hawthorne Overcrossing Bridge, and then right after that, Alex is gonna join me up here, and we're gonna talk about the read market bridge. So, quick introduction, Ryan Oster, uh director of our engineering department. John Bresciers, architectural applications, we are the bridge architects. And Craig talking, KPF structural engineers. And as the mayor said, this is really truly just more informational. We're not asking for any specific decisions tonight. At the end of this presentation, I have a schedule slide where we'll give you a sneak peek of some of the things that we will be bringing back to council after a future open house meeting. So to kick us off, I'll hand it over to John. Yeah, thank you very much. Just very briefly, I wanted to try and take you through what's what we're aspiring to and what is inspiring us to develop this project. Every place has its own unique sense of identity. Uh I think we all know that and we all feel it, whether we're aware of it or not. This place has a particularly strong one, and so much of that is governed by the cascade peaks. Uh they're just really prominent. And I think all of us, I'm talking about as an entire species, are very much drawn to mountains. They make us think of permanence, they make us think about time in ways we don't normally think about it on a geologic scale. And they're very, very powerful. Uh they also tend to change all the time. These kind of ephemeral atmospheric effects, the light, the mist, the clouds is continually changing, and they they present these sort of layered vistas that have some perspective and some depth and draw us in. So we're trying to embrace all of that and come up together with you with a bridge that is really anchored in the identity of this place and grounds it without slavishly trying to imitate the mountains or the history of bend, but give something that is really endemic to this place. Uh so with that, I'm gonna let Craig talk about where we are with that effort. So this is as an idea of the mountain peak idea. Um if you think about like a gable and an attic gable. It's a it lends itself a truss system with the if you kind of invoke that mountain thought. It's a it's a trust is a very efficient structural system. That's why you see an older structures especially. Uh but that triangular shape is a stiff and efficient structural way to make a span. So what we did is we take we took that mountain theme with that triangular uh concept with a truss that we created two different layers of trusses trusses. If you see there on one side, there's the typical, as you would think, a gable trust that you would see in an attic, uh so to speak. On the other side, we've uh what we've done is we've taken that that concept and extended it out over the supports. So structurally, the the depth of the the truss is is where the all of its stiffness comes from on with that continuous span, the two mountain theme there we have on one side over the support, is where the depth is to again give us that efficiency. So it really provides a very efficient structural system to make a span, and that's why you see them through the ages in terms of trusses and how they've been developed. What we're using are typical uh say off the shelf, but the very common structural steel shapes that are available. They can maybe may do a mill roll here, or they may be available just because these are fairly common shapes. And joining them in a way that um uh minimizes field erection and field fabrication time. These will be bolted together to again from an efficiency point of view to keep most of the work in the fabrication shop on the field work to a minimum.
