A Coffee With… Colorado Transportation, Structures, and Water Resources

With many disciplines working together on a variety of projects, perhaps the best way to get a feel for a firm’s impact is simply, a coffee with… the people doing the work.

This video series features experts sharing insights gained during their time in the AEC industry, with an emphasis on the importance of collaboration to meet a common goal of creating improved communities.

In this edition, we sit down with leaders in transportation, structures, and water resource engineering from the Colorado region. Hear how their work overlaps to enhance both mobility and sustainability for communities.

Hear the full conversation in the video above and check out the transcript below:

Kevin: All these things, there’s so many details that go into the process, and before you know it, you look up and it’s built, and you’re like, “Wow, this went pretty well.”

Introductions

0:14 [Skip to this chapter]

Kevin: Hi, my name is Kevin Dooley. I am the Business Unit Leader of Transportation and Infrastructure here in Colorado in the Rocky Mountain West region for Otak.

I have about 20 years of experience in the industry, depending on when you start counting.

Tracy: I’m Tracy Emmanuel. I’m the Business Unit Lead for Water and Natural Resources for the Colorado region. Started my professional career as a fluvial geomorphologist working in the Pacific Northwest, and then most of my career has been back here in Colorado.

David: I’m David Graff. I’m the Structural Engineering Business Unit Lead in Colorado. I’ve been in the industry for about 15 years, and at Otak for about nine.

How does your infrastructure work help communities thrive?

0:59 [Skip to this chapter]

Kevin: These are often major safety upgrades for a lot of people. They’re much needed projects. And I think making sure that we’re addressing the needs of the community in the project goals. That’s one thing that always stands out to me after these projects are built.

Whether we’re getting cyclists off of a three-foot paved shoulder that was built in the ’60s and putting them on an eight-foot paved path behind the curb, to sight lines associated with retaining walls, replacing old infrastructure associated with bridges; and then also the work that goes into analysis of the floodplain. Obviously, that has this huge scope that we need to take into account on these projects, and it’s great when it works together and comes out.

Tracy: Being able to support our communities, I think that’s a big driver for our whole office, which is fun for that environment for us to be all having that goal in mind, or that driving passion for our communities.

And, for us, having rivers and streams that are in reasonable condition for generations to come. And then for folks to be able to get to them via bike or hike or what have you, I think is a fun overlap with all of our teams.

David: I really enjoy the fact that many of our projects are very local to us. That we get the opportunity to go out and use the projects that we’ve designed once they’re finished and once they’re constructed.

I think it really makes you think about the design in just a little bit more detail, knowing that you and your family and your friends are going to be the ones going out to use these projects.

Tracy: Mm-hmm. Yeah, agreed. Just a couple of weeks ago, we did the happy hour where we rode to the happy hour location via all of the trails and bridges and crossings and underpasses that you guys have designed.

It was pretty darn special for Scott [Belonger, active transportation lead] to be giving us a tour of all the different sites, and it was right here. We rode right from our office, which I agree, I think that’s pretty special.

What does multidisciplinary collaboration really look like?

3:20 [Skip to this chapter]

Kevin: Our structures and roadway and trails and transportation groups have historically collaborated very frequently. I mean, almost on every project, right?

And I think the benefit of that is us, our staff, have learned a lot about each other over the years. And so you get to wear many hats, you know what I mean? You start to think like a structural engineer, or a structural engineer may think a little bit more like a roadway or transportation engineer.

I think that that’s the great opportunity and the beauty of working together in a multidisciplinary group such as ourselves.

Tracy: It’s not always perfect. I think as we’re working through bigger and bigger projects, I feel like we’re learning from maybe mistakes or where things could have gone smoother. And I think that’s huge in terms of the next big projects.

I think the biggest lessons learned are communication early and often. I feel like you say that, and it’s like so what? But it’s very true.

David: And I think we’re also learning how to all speak each other’s languages, at least on a conversational level.

Learning what are the constraints of a 1D versus a 2D hydraulic model, and when you use one, when you use the other. Even just having a low-level understanding of that can help me understand what are the limitations of what’s being done and how that impacts the design of our portion of the project.

Tracy: Yeah. It’s a learning process, right?

Kevin: It is. And now that we’ve grown in that we’re starting to work on larger projects together. What’s really important to collaboration is not working in silos but understanding how each group affects the other.

Navigating complexity on a unique mountain trail

05:22 [Skip to this chapter]

Kevin: One project that stands out recently is the Maroon Creek Trail project. That was a trail project up in Aspen that was needed and on planners’ minds for a long time.

And the reason it hadn’t been done is because it was challenging. There was challenging right of way, there was challenging drainage and existing structures, dealing with a lot of the local schools.

We approached it with all of those needs in mind and came out with a project that just was great. It’s hard sometimes to fit a public trail and that type of a transportation, mobility trail within a really tight corridor like that and have it fit so well into a landscape.

David: That project, the solution, and I think where Otak works really well is after it’s been built, it feels as though the solution was obvious, but the solution was not obvious.

That had to be worked through. The problems were challenging because it had been so many years on the docket is because there wasn’t an obvious solution.

And then once we came in and we solved the problem in a way that does feel obvious, we almost become a little invisible to that. But that’s the kind of space that we like to work in where we do have to work together with the trail, the river, the structures all have to work together in tandem to provide a good solution.

Small changes become big eureka moments in Breckenridge

7:08 [Skip to this chapter]

David: I think Blue River Pathways is maybe a good way to say it. It was a path rehabilitation, [pedestrian bridge design] replacement, and river restoration project. Because it did go right through the middle of downtown Breckenridge, it was a very constrained project that really required a lot of coordination.

If one team said, “Hey, we need to make the structure a little longer,” well, that impacted the trail, or it impacted the river. So, at every point, if one team needed something, it was taking away from someone else.

Kevin: Those eureka moments don’t always have to be these huge things. They can be something really small.

Like placing a curb and gutter on our approach to the underpass on the high side of the trail. Those little design details solve a lot of problems down the road.

David: Absolutely, yeah. We skewed the box by seven degrees, the underpass, and that helped with so much more of the river capacity that then downstream we didn’t have to do as much work because we were able to just rotate the structure.

And that was something we didn’t consider because we always, at least as a starting point, put a box perpendicular to a roadway because that’s the most efficient from our standpoint. But then once that was recognized, it’s like, oh, it doesn’t really change much for us, but it’s huge for the river.

Tracy: Yeah. That’s a good one.

There’s probably a lot of understanding, to your point, the terminology and saying, “okay, why does this change impact the floodplain?”

So, I think there was probably a lot of that, just information sharing. So that it’s clear if someone makes a minor change in the structure, that it’s going to impact whatever we’re doing for the floodplain permitting.

Defining & finding success on projects

9:02 [Skip to this chapter]

David: So many of these projects are for our local municipalities to where they’re intended to be used.

And so going out and seeing people using it, enjoying it, and noticing some of the details that we put in, something that probably could’ve had lots of conversation, lots of work to get it in there, and seeing people notice it or talk about it… is, and yeah, appreciate it, is very satisfying.

Tracy: Just thinking about projects that have been rewarding and that there’s a moment that you’re like, “Oh my gosh, this was so great,” right?

I’ve told this story before because I feel like it’s so iconic for, well, me and how I look at projects and how I look at the success of the projects; but we did a diversion replacement on South Platte years ago, and it was for fish passage and for resiliency, for operations, all the things, and we worked with David’s team on this as well.

During construction, they constructed the diversion, they constructed this fish passage channel, right? So the channel where the fish are going to be able to move up and down. And after the sections were constructed, the water was released into that area. And I went out there the next day and was walking it just to see how it was functioning, and there was a fish in part of the little section of the channel.

And it just, for me, I was like, “Oh my gosh, this fish may have never been in this part of the river,” right? I think it was just meaningful because I think it was immediate that there was a success point of, yes, it’s a fish, but that’s kind of our client in a way, too, in some of these projects. So it was kind of a fun aha, like, “Yay, we’re doing good stuff.”

Kevin: Yeah, similarly, I can think of a project example of Kaufman Street in Longmont that we did. And there was a lot of effort into reconstructing and redesigning seven blocks in an urban corridor, taking a historic older roadway that had on-street angled and parallel parking, and very small sidewalks, and fronting everything from businesses to public entity buildings and private property, single family.

There’s just everything in seven blocks that you could imagine. So all that effort that we put into it and the plans and the details, I think it makes it worth it, going that extra mile during the design to make sure things are really going to work themselves out in the field, and then have it come to life on the ground, and seeing people use it, and I think it’s great.

Tracy: I had ice cream sitting on the side of the street there, at Sweet Cow. Just this weekend. We sat there and I was like, “Wait, I think this is our project.”

Kevin: Yeah. This is our project.

Tracy: And it looks very nice. It looks very nice. Yeah.

A recent open house and ribbon cutting at the North Kitsap Service Center offered the public a first-hand look at the enhanced and expanded facilities found across 16 acres in this area of Washington between Olympic National Park and the Puget Sound.

The event welcomed the public to take self-guided tours of the site which includes a new 17,842-square-foot Road Operations Facility as well as a second building for the safe disposal of household hazardous waste. Members of the Otak team – Jeff Massie and Bob Doherty – we’re in attendance to commemorate the moment for the community after leading the architectural design and engineering of these facilities to completion.

More information about the design features and expanded capabilities of these new facilities can be found below.

About North Kitsap Service Center

Updating and adding to facilities dating back to the first half of the 20th century that had grown obsolete, the North Kitsap Service Center was designed to maximize the county’s services for the surrounding communities. This includes the now more than 900 miles of roadway it preserves and maintains, as well as capacity for household hazardous waste collection, a service that previously required community members to travel more than 20 miles.

A focus on sustainability is found in features throughout the facilities. From a photovoltaic system for generating electrical power to heavy duty electrical vehicle charging, the design adds efficiency to its operations that also maintain the county’s fleet of service vehicles. Internal and external stakeholder engagement was an essential piece to the final design and delivering these new assets to the community.

About 1st and Strand

With an eye on economic growth and enhanced public use, work at 1st and Strand creates multimodal access to new public spaces while adding infrastructure for future development. The transportation design includes a multiuse path and roundabout that accentuate the waterfront of downtown St. Helens, Oregon. For an area that includes city hall and other public buildings, the ability to close off a portion of the street for festivals also contributes toward the city’s goals to enhance its usage for the community.

Complete Streets: How Policy and Design Shape Urban Mobility

Communities thrive with greater connectivity. When this includes a multimodal approach that’s designed to accommodate users of all ages and abilities, it can be referred to as complete streets. The concept redefines the design of roadways to support a more holistic view of mobility, shifting from vehicle dominated corridors to spaces that serve everyone.

Complete streets are uniquely positioned to meet multiple goals at once. Increased public accessibility unlocks opportunities for economic growth, enhanced infrastructure, and improved public health. It not only promotes sustainability with active transportation and green infrastructure but also improvements for motorists with safety and traffic calming features.

Graphic introducing the topic of complete streets.

Comprehensive in nature, a complete streets policy can also be complex in its implementation. Each community has its own needs, constraints, and priorities, meaning complete streets must be thoughtfully tailored to their context.

In this blog, we’ll explore what complete streets are, the common elements that make them effective, and the process of creating policies leading to projects that bring them to life.

What Are Complete Streets?

Complete streets are an approach to planning, designing, building, operating, and maintaining streets that enable safe access for people of all ages and abilities. Rather than focusing primarily on vehicular traffic, this approach considers how all users interact within the transportation network to increase efficiency throughout.

At its core, complete streets emphasize multimodal transportation. This means integrating infrastructure for pedestrians, cyclists, transit users, and motorists while also adding improvements to infrastructure like stormwater management. The goal is to create streets that are not only functional but also inviting and efficient, improving both mobility and overall environment within a corridor.

Examples of Complete Streets Design Features

Complete streets incorporate a variety of design features that work together to improve access to businesses, essential services, and public spaces. This often leads to comprehensive improvements along a corridor impacting multiple aspects of public infrastructure.

Tualatin School Pedestrian Improvements

Removal of barriers to students biking and walking to Tualatin Elementary also reduces roadway congestion in the area to improve safe routes to school.

To account for added impervious surfaces across the Tualatin Moving Forward Bond Program, a vegetated swale is designed to treat stormwater in the area with green infrastructure.

Roadways

Roadways can often be barriers to broader accessibility. While complete streets place less priority on a community’s vehicular traffic, improving roadways for their use is no less important. Taking a wider perspective, the design often seeks to reduce overreliance on cars, improving safety and traffic for everyone in the area.

Features such as wider shoulders, curb extensions, and roundabouts are commonly used to calm traffic and reduce speeds. These elements enhance safety for both drivers and pedestrians while maintaining efficient road diets. The result is a roadway that’s safer and more integrated with other modes of transportation, removing barriers for all.

Sidewalks, Bike Lanes, and Multiuse Paths

Active transportation infrastructure is a defining feature of complete streets. Sidewalks, bike lanes, and multiuse paths are designed to create safe and convenient options for people who walk, bike, or use growing forms of micromobility.

Municipal policies often guide these features, such as requiring sidewalks of a certain width along new developments. Increasingly, designers must also account for emerging transportation modes like e-bikes and e-scooters, as well as designated spaces for rideshare services that do not disrupt traffic flow. These improvements benefit local businesses by increasing accessibility and walkability. When people can reach shops and services without a car, it expands the customer base and enhances the overall experience of an area.

Accessibility is essential to this goal. Features like pedestrian bridges, median islands, and well-marked crosswalks with updated signals help ensure that streets are safe and usable for individuals of all abilities.

Transit Stops and Bus Lanes

Public transit plays a vital role in complete streets. Integrating transit options such as bus rapid transit or light rail helps reduce congestion and provides reliable alternatives to driving.

Dedicated bus lanes can improve efficiency by allowing transit vehicles to bypass traffic, making service faster and more predictable. Equally important are the transit stops themselves. Comfortable, accessible, and well-designed waiting areas can significantly improve user experience and encourage more people to use mass transit. Providing adequate space for waiting passengers, along with amenities like seating and shelter, contributes to a more welcoming and functional system.

Stormwater Infrastructure

While it may not be the first thing that comes to mind with transportation, stormwater infrastructure can be one of the most important features. As with any roadway, complete streets must effectively manage water runoff, especially as these new developments can increase impervious surfaces, or change existing conditions.

These requirements can lead to opportunities to integrate green stormwater infrastructure solutions. A nature-based design approach may use features such as vegetated swales and rain gardens to not only manage water efficiently and with low impact, but also to enhance the environment of a corridor.

Parks and Green Space

Complete streets often connect to parks, trails, and other recreational areas, expanding their reach and usefulness. By linking neighborhoods to regional trail systems, these projects can improve mobility across larger areas.

Green spaces add recreational value while also supporting environmental functions like stormwater management. Amenities such as bike racks, benches, and open spaces create new opportunities for alternative transportation and outdoor community activity.

Creating a Complete Streets Policy

Implementation of a complete streets design begins with a complete streets policy. This process, which can often take shape through comprehensive planning, establishes a framework for how streets will be planned and designed, ensuring consistency and alignment with community goals.

Because every community is different, policies must be flexible and context-sensitive, reflecting local priorities and conditions. There are several essential elements to that effort.

Build a Team of Stakeholders

A successful complete streets initiative begins with assembling a diverse group of stakeholders. This often includes neighborhood organizations, government agencies, elected officials, public safety advocates, business groups, and design professionals.

Property owners are especially important to be involved, as they may be directly impacted by changes. Early collaboration helps identify concerns, build consensus, and create a shared vision for the project.

Align Regulation and Requirements

Regulations can play a significant role in shaping complete streets policies. Municipalities might require a minimum sidewalk width around redevelopment or have a Vision Zero policy directed at eliminating transportation related injury and deaths.

These requirements can not only guide design decisions but also be used to advance complete streets initiatives that enhance safety. Shifting responsibility toward system designers, such as engineers and policymakers, the focus moves to safe speeds, forgiving infrastructure, and equitable, data-driven actions, rather than relying solely on individual behavior.

Identify Deficiencies and Opportunities

From an engineering perspective, the design process begins with evaluating existing conditions. Identifying gaps, from missing sidewalks and inadequate transit stops to a lack of bike infrastructure, helps define priorities and opportunities for improvement.

Designers must also account for constraints like existing utilities, walls, and right-of-way limitations. Traffic data and modeling can inform decisions about lane configurations, including opportunities for road diets or additional capacity where needed.

Community Engagement

Engaging the community is essential to creating successful complete streets. Public input helps identify desired features, anticipate how spaces will be used, and build support for the project.

Engagement can range from working with key stakeholders to broader public outreach efforts. Ultimately, incorporating community feedback ensures that the final design reflects the needs and values of the people it serves.

A Multidisciplinary Approach to Complete Streets and Vibrant Communities

Complete streets represent a shift toward safer, more connected, and sustainable transportation systems. They’re designed to safely accommodate pedestrians, cyclists, transit users, and motorists by integrating multimodal infrastructure, accessibility features, green spaces, and stormwater management. With thoughtful policies formed through a diverse set of stakeholders, these solutions are tailored to each meet the local needs of a community.

The approach ultimately helps foster neighborhoods where people of all abilities benefit from more vibrant, functional, and inviting environments for generations into the future.

A collaborative effort between multiple municipalities and a multidisciplinary Otak team reached a significant milestone last week with a ribbon cutting ceremony at Miller Creek. Stakeholders from Port of Seattle, the Cities of Burien, and SeaTac, gathered alongside project leads to celebrate the completion of 1.4-acres of restored floodplain designed to enhance habitat for endangered salmon and reduce flooding for the surrounding community.

The project is just one piece of the Northeast Redevelopment Area (NERA) where master planning set a vision for economic development near the growing regional airport. In addition to the green stormwater infrastructure and environmental enhancements, the design also opened the area to greater public recreation with access to the regional trail system.

About the Miller Creek Restoration

To support redevelopment of a 162-acre subarea near the expanding SeaTac International Airport, the restoration of Miller Creek improved stormwater capacity, natural habitat, and public use. By daylighting 900 linear feet of a stream that previously flowed through a failing pipe system, the project also adds protection for private property and downstream wetlands from runoff. The restored stream will now also provide important natural habitat for endangered salmon and other aquatic species by bringing it to the surface and removing other barriers to fish passage. These efforts contribute to broader efforts to restore the Puget Sound Watershed.

For more than 65 years, the annual ACEC CO Engineering Excellence Awards (EEA) have been highlighting projects that demonstrate an exceptional degree of innovation, complexity, achievement, and value. Learn more about how the Maroon Creek trail met these criteria to enhance mobility, safety, and environmental stewardship in this iconic Rocky Mountain setting.

About the Maroon Creek Multiuse Trail

The Maroon Creek Multiuse Trail provides a safe, non-motorized, and clearly-defined connection throughout the City of Aspen. Integrating with the city’s 22 miles of existing trails, it provides year-round access between the city’s neighborhoods, schools, and downtown core. This includes priority locations such the Aspen Recreation Center transit hub, Aspen Highlands Ski Area, and Maroon Bells Scenic Area. By encouraging walking and biking over vehicle use, this asset supports local climate goals while also reducing traffic congestion.

The trail has become a visible symbol of engineering’s role in promoting active transportation and environmental stewardship. As part of an extensive public engagement, the final design gave careful consideration of adjacent properties while giving priority to community input and ensuring fiscal responsibility. With steep slopes, limited right-of-way, sensitive wetlands, and proximity to a major waterway, the Maroon Creek Trail design addressed a variety of complex challenges. A combination of technical ingenuity and stakeholder collaboration successfully navigated these constraints, including extensive hydrologic modeling and specialized materials to accommodate seasonal freeze-thaw cycles and avalanche-prone areas. A careful balance of roadway separation and physical barriers were part of a creative approach to setting trail alignment in narrow settings.
