Central Texas’ population is growing rapidly with several of Austin’s suburbs ranking among the fastest growing cities in the country. Smaller and traditionally more rural communities and counties are seeing residents flock to their towns, driven by a variety of factors. Furthermore, businesses such as Samsung, Apple, and TESLA are heavily investing in the region, and large cities like Austin are continuing to grow.
As communities experience rapid growth, how can they update and adapt their transportation plans to minimize growing pains? How can planners continue to attract and maintain business investment and residents while ensuring that growth doesn’t outpace infrastructure capacity?
WSB’s Texas team is at the forefront of helping counties and communities create and execute comprehensive transportation plans that are flexible, nimble and take a long-term view of community growth and resident needs. Here are some lessons learned in Texas that apply to communities across the country experiencing rapid growth.
What happens when a transportation plan doesn’t meet the needs of a community?
When cities and counties fail to adequately plan for and invest in transportation infrastructure, residents and businesses often experience negative repercussions. Insufficient transportation planning can lead to congestion, decreased mobility and accessibility, safety concerns, and can ultimately hamper further growth and investment in the community.
Community leaders must understand the relationship between transportation infrastructure and economic development and investment. Is there enough housing for workers? Are workers able to easily get to and from work without overly burdensome commutes? Are there public transportation options that meet the needs of residents and businesses? Plans must provide answers to these questions and factor in a variety of needs.
Transportation infrastructure is a major consideration for businesses who are looking to expand or relocate. Investors consider access to markets and local/regional transportation connectivity when deciding on the location of new ventures. When transportation plans fail to meet the needs of a community, they are less likely to attract and retain businesses, investment projects and industrial development. Transportation planning that supports growth means ensuring residents and visitors can travel the community freely, efficiently and safely.
How to craft a transportation plan that has a long-term vision.
Proactive transportation planning is essential to ensure that the community can support growth. Community leaders need to advance comprehensive transportation plans that have a broad, long-term vision for their community over the next several decades, while regularly reevaluating to see where changes need to be made and priorities may have shifted. As population growth and economic development accelerate, it is vital to evaluate the existing transportation infrastructure’s capacity to handle the growing demand. Identifying potential bottlenecks, road networks operating beyond their capacity, and inadequate public transit systems can prompt the need for changes in long-term transportation plans.
Long range transportation plans can also help reduce potential future conflicts. Identifying the location of future roadway corridors and incorporating them into development plans can minimize the need for residential and/or commercial displacements. A prime example of preparing transportation projects for the future is the work done in Williamson County— one of the fastest growing counties in the country. In preparation for population and economic growth, new location routes that are identified in the county’s Long Range Transportation Plan in undeveloped portions of the county are studied and designed. In doing so, the plan accommodates population expansion, allowing for continued growth and minimizing potential future conflicts.
At the end of the day, a plan should build a solid foundation for the future, and be flexible and nimble to accommodate emerging trends.
Understand the value of public engagement.
Not in my backyard! Communities are all too familiar with pushback from residents and local businesses when people feel community plans will negatively impact their home, neighborhood, business, or city. Lack of local connection and public input can worsen these issues when things like new roadways, zoning changes or other transportation investments are advanced. Proactive transportation planning allows for greater public engagement earlier in the process, helping reduce resident push-back in the long-term.
Furthermore, comprehensive planning can also foster better coordination between stakeholders and different areas of local government (like cities and counties), helping make processes run smoother and ensuring transportation visions are aligned and meet the needs of the region.
Plan for emerging technologies.
Booming populations aren’t the only thing that transportation planners are looking at – they are also exploring how emerging technologies will impact their plans. The electrification of vehicles requires planning for a robust and accessible charging infrastructure with strategically located charging stations along major corridors and at key destinations. Furthermore, autonomous vehicles are also an emerging technology that may dominate our roadways in future decades. Planning for emerging technologies and putting the proper infrastructure in place now will put communities ahead of the curve and reduce conflicts in the long-term.

Investing in the vitality of the city of Lino Lakes, Minnesota.
At WSB, we use the term infrastructure broadly to define the places, spaces and systems that support our lives. As important as infrastructure is to our way of life, we don’t often think about it until something goes wrong. We’ve been privileged to support communities across the U.S. with their infrastructure needs. The scale of the projects may vary, but the impact is always significant.
For the last several decades, the city of Lino Lakes, just north of the Minneapolis-St. Paul metro, has been investing in their infrastructure across the community. In the end, it’s not one single project that has helped to build a vibrant community, but rather the collective investment in varying infrastructure. These investments have played a vital role in spurring development and progress within the city.
1. Biological Water Treatment Plant
The city is currently planning to construct a water treatment plant due to some of the city wells having manganese levels above the recommended guidelines. A biological treatment approach is unique because it relies on natural microbial activity to remove contaminants rather than chemicals, an environmentally sustainable strategy.
2. West Shadow Lake Drive
West Shadow Lake Drive is a residential street that was plagued by potholes, had no sewer or water, and faced challenges from high groundwater levels due to its proximity to Reshanau Lake. As part of the city’s pavement management program, the road was removed and replaced to support the city’s roadway infrastructure and sanitary sewer, watermain and storm sewer infrastructure was also installed. In addition, environmental work and wetland enhancements occurred throughout the area.
3. 12th Avenue Trail Project
The 12th Avenue Trail connection was identified as a priority in the city’s Comprehensive Parks and Trails System Capital Improvement Plan due to the lack of trail connection along 12th Avenue. Prior to project completion, the busy rural road was narrow with unsafe conditions for pedestrians and cyclists. The project resulted in increased safety and a more bikeable, accessible community.
4. Master Plan and Comprehensive Stormwater Management Plan
Located in the northeast corner of Lino Lakes is a 1300-acre greenfield area that is prime for development opportunities. WSB was contracted to develop a master plan, comprehensive stormwater management plan and update the Alternative Urban Areawide Review (AUAR) for the area. Development opportunities will include residential, industrial and commercial that will spur economic activity in the area.
5. The Rookery Activity Center
When the local YMCA closed in 2020 it left a hole in the community. The city of Lino Lakes took action to reinvigorate the space. To establish itself as a new asset within the community, the building needed an overhaul, not just in amenities and programming, but also the brand. WSB worked with the city to develop a story, identity and brand assets.
6. Tower Park
Tower Park is located on a 60-acre piece of land that was purchased by the city over 20 years ago. The city council felt strongly about developing the space into a destination recreation area for the community. WSB provided the park master plan and phase 1 design support. Tower Park is now home to some of the city’s most popular pickleball and tennis courts. The project was completed last year.
7. Birch Street Roundabouts
Birch Street is a heavily traveled roadway through the city with frequent accidents occurring due to the number of entrances to the high-speed roadway. There were safety concerns from residents and a nearby school. To help alleviate the number of accidents and increase safety, several roundabouts, medians, crosswalks and safety signage were added.
8. Gateways to the City – Placemaking
Lino Lakes is a proud community and wants to enhance their welcoming presence by creating placemaking monuments at city entrances. The project is still under development, but once complete, the entrances will offer a ‘front door’ to the city and will invite visitors and residents to step inside and explore the community.
9. Feasibility Study – Lake Amelia Subwatershed
A 255-acre subwatershed of Lake Amelia is currently undergoing a feasibility study to address existing stormwater management concerns and anticipated future land use changes to the area. The short-term phase includes solutions to address flooding concerns. The long-term phase proposes more holistic improvements to the corridor that that would occur alongside its eventual development. The study will help guide future planning in the area and will ensure that the area is prime for development.
10. Shenandoah Park Improvements
In partnership with the Rice Creek Watershed District, the city is exploring multiple improvements to the Shenandoah Park area to improve water quality, ensure its habitat is supported, and create a destination for park users. WSB is currently exploring water quality improvement options, wetland restoration, flood retention and greenway spaces to support the goals of the watershed district and the city.

Relieving the gridlock.
Located in Montgomery County, the 7th fastest growing county in the U.S., is the city of Magnolia, Texas. Well-known for its access to the Texas Piney Woods and sprawling magnolia trees, the city is nestled in the southwest part of the county and is situated along the heavily traveled FM 1488.
For years, the community has been managing severe congestion, safety issues and significant delays at the intersection of FM 1488 and FM 1774. As the city of Magnolia and the surrounding areas continue to experience record growth, the congestion has only worsened. Not only is traffic a concern, but vehicles heading east-west along the corridor need to travel over a railroad, creating another complication.
Solutions to the bottleneck.
Many ideas have been vetted to alleviate the traffic – most of them resulting in substantial impacts to the historic downtown Magnolia. To ensure the community keeps its economic footing, a bypass around the town was proposed. The $114 million Magnolia Relief Route will include five miles of new four-lane roadways that will extend west from FM 1488, cross over a Union Pacific Railroad track, and connect with the Texas 249 tollway.
Accelerating the timeline.
The project has been on the Texas Department of Transportation’s (TxDOT) list for nearly a decade. To accelerate the timeline, WSB is delivering the project through 3D digital delivery. Digital delivery results in efficiencies, and speed that would not be possible through traditional design delivery methods. The timeline from schematic design to final will take less than eight months which will then allow the county and city to have plans finalized when funds become available.
Toll revenue and project funding.
The project will partly be funded through toll revenue from Texas 249, a state-operated toll road. FM 1488 will connect to Texas 249. In Texas, any new facility that brings traffic to the toll road is eligible to be funded out of the toll revenue. Additionally, $10 million was earmarked by Montgomery County as part of the required match in the 2015 road bond. The project is anticipated to be bid in 2024.
Union Pacific Railroad Permitting & Coordination
By the Numbers
5 miles of new roadway
$114 million project
8 month accelerated timeline
Eliminates 15,000 vehicles each day from crossing the Union Pacific Railroad at-grade crossing.
As Vice President, David will be responsible for driving business and working across many markets in the region including the department of transportation, toll road authorities, county government agencies, transit authorities, port authorities and local municipalities. In addition, David will support projects in the private sector, working closely with land developers, commercial interests, oil and gas and pipeline transport.

Disrupting the traditional process
Machine control modeling has been part of the construction industry for over twenty years, but as the industry faces supply chain challenges and a lack of available labor, the need to streamline and create efficiencies is only increasing. As designers, contractors and teams strive to complete projects efficiently and accurately, new innovations and approaches are changing the way the industry is approaching machine control modeling.
In a traditional approach to machine control modeling, a contractor will receive 2D design information that has to be recreated in 3D. Although there are many benefits that result from this process, there is still too much room for human error, a lack of conflict identification and unbalanced earthwork quantities.
From 2D to 3D
As digital delivery methods continue to drive our industry, our goal is to migrate away from having 2D plans for construction. In many cases, working off a 2D plan and a 3D model can be controversial, causes confusion and is contradictory. A deep understanding of the needs of contractors, owners and designers allows us to develop one true source of design information in a 3D model that streamlines the process. Through cutting-edge tools combined with our expertise, we develop a 3D model that is useable in the field for grading model systems. This is just one of the many construction benefits of developing a single source of truth in a 3D model. The 3D model serves as the foundation for all information needed to deliver a project because of its accuracy and end user capabilities.
The top ways design firms are changing the way contractors approach machine control.
Custom Machine Control Files
Contractors have unique needs. They rely on accurate models because it replicates exactly what needs to be built. To support this, we develop custom machine control files that eliminate contractor conversions and modifications. These custom files are usable in Trimble, TopCon and LEICA contractor systems.
Validation of the 3D design on both sides
The use of a 3D model allows for the validation of information within the design platform and the contractor platform (TBC, Magnet) eliminating the need to rerun earthwork. A high-quality 3D model improves project outcomes. Oftentimes, owners will use a 3D design model instead of a standard design model because of the significant benefits. In any construction project, expectations of a contractor are high. A 3D model ensures accuracy and eliminates construction failure or a perception of cut corners from the owner.
Identify errors immediately
When contractors work directly with a team that has a deep understanding of design and field needs, the process is significantly streamlined and more accurate. Once a 3D model is created, errors are identified even after the bid process, providing a more accurate building process before construction even begins.
Relying on models to guide the project
Layout models match grading models. With one mode, there are less surprises in the field. A model also reduces the manhours and survey supplies needed. In the past, a surveyor would layout ‘whiskers’ every 50-feet. A model eliminates this need, resulting in smoother roads and less cording. In addition, communicating with an owner becomes easier. Owners want to see the completed surface model look exactly like the design. A 3D model aids in communication and collaboration.
Reduce costs and staff
With greater confidence in grading model accuracy, the changing landscape of operator ability won’t have an impact on projects. There is less skill required when working with one true source of information. Additionally, with a high-quality 3D model, there is a less likely chance that work progress will not match up. Using this advanced design technology prevents accusations of poor construction, also eliminating the possibility of additional costs to fix issues forced onto the contractor.
Exact quantities and information results in the reduction of materials. Contractors are reliant on a 3D model because they are paid based on the volume of materials calculated by the model. With the model, quantities are precise, eliminating the small extra quantities in the corners that add up quickly. An accurate 3D model prevents an excess or shortage of materials.

In just a quarter century, the number of roundabouts has increased 3,000 percent across the country. Roundabouts are growing in prevalence because of how they can effectively, efficiently, and safely move traffic. Numerous designs and geometric shapes allow roundabouts to seamlessly integrate into our transportation infrastructure.
Below are five facts about roundabouts – an infrastructure trend that’s here to stay.
1. Roundabouts improve safety.
A major reason that roundabouts have grown in popularity is because of their safety record. The designs help prevent serious crashes and fatalities. Slower speeds and the angle at which cars enter roundabouts significantly reduce the probability of head on and T-bone accidents. Multi-lane roundabouts may have property damage only crashes when they are first introduced, but the chances for fatal or injury crashes drop significantly. In most cases, crashes at roundabouts are fender benders.
Pedestrian safety is also improved at roundabouts, although this can be a difficult concept for some to understand. Most feel that because there is not the presence of a signal telling the motorist when to stop and the pedestrian when to go, that it cannot be safe. However, there are several reasons the pedestrian crossing experience is improved:
Shorter crossing distance
Fewer conflict points
Navigating traffic from one direction and refuge islands
The pedestrian crosswalk is pulled back from the yield line allowing drivers to make a decision at the crosswalk before entering the roundabout
What’s more, because of their safety track record, they score well with many federal programs and are often eligible for grant funding.
2. Roundabouts handle high and low volumes efficiently.
Have you ever sat at a light for what feels like forever, even when there is no other traffic around? Roundabouts solve that problem, providing self-optimizing control. Roundabouts keep traffic moving. Roundabouts handle both high and low volume traffic well. The effect of a rolling queue creates a situation where delay seems more acceptable to the driving public. In the early 2000’s, many roundabouts were overbuilt based on the modeling results. Many multi-lane roundabouts have since been retrofit to simpler geometry, and still perform operationally well.
3. Roundabouts significantly improve access management in busy corridors.
In areas where there are many driveways and businesses along a corridor, it can be difficult for exiting traffic to turn left onto busy streets. The implementation of a roundabout corridor allows left turns to be eliminated while access is maintained and for drivers to make a U-turn. This creates a safer and efficient corridor.
4. Roundabouts have growing buy-in from the public.
When communities begin building roundabouts, there can be a fair amount of skepticism and concern from the public. As more communities adopt roundabouts and more drivers have successfully used them, that skepticism is significantly reduced.
In communities that are new to roundabouts, a robust public engagement strategy is executed to educate the public. Public engagement tactics often include modeling, educational materials, visualizations and myth busting presentations that dispel the myths and provide education about the roundabouts, .
5. There are times when roundabouts are the wrong design choice.
While roundabouts are a growing trend, they aren’t right for every situation. Areas with high traffic volumes in one direction, with limited left turns on or to the side street, may not be ideal for a roundabout, as appropriate gaps may not be created. If roadways are already designed for traffic signals with multiple lanes, it may be more efficient to install traffic lights as opposed to redesigning a street for a roundabout.
Roundabouts are growing in popularity for a reason and are here to stay. Efficient traffic flow, improved safety, and operational efficiency make them a smart infrastructure choice for many communities.
Roundabouts move people and communities forward.
Andrew is a transportation project manager and lead design engineer with over 20 years of experience who has designed more than 80 roundabouts. He is involved in all aspects of roundabout design, including geometrics, traffic operations, staging, and adhering to ADA standards. He has educated communities on the benefits of roundabouts and their safety for managing traffic. Andrew has also shared his professional knowledge nationally at international roundabout conferences.
