This project was the second phase of parks implementation outlined in the District's Parks Master Plan, which was completed by EHRA in 2007. Utilizing the site of a recently demolished former wastewater treatment plant provided an opportunity to create a passive park space for District residents.
In 2006, Caldwell Companies sought to create Towne Lake as a community where residents and services could be connected by water. Their vision included boat docks and marinas augmenting traditional walking trails to navigate a vibrant residential community. EHRA was the perfect partner to take Caldwell Companies’ vision and create this livable suburban oasis.
Engineering design and construction phase services of water, sewer, drainage and paving for four subdivision sections and off-site channel (123 acres out of a 400 acre subdivision). There was 60-feet of elevation difference on this site and wooded lots were left in their natural state which required the installation of retaining walls.
EHRA planners, hydrologists and landscape architects worked together to propose an alternative use for the space, re-developing the basin into an amenity pond. EHRA carefully selected native plant materials for both their ability to survive in the harsh conditions of the basin as well as providing filtration for improved storm water quality.
EHRA completed preliminary engineering, phase one environmental site assessment and schematic development for the widening of Northpark Dr. between US 59 and Woodland Hills Dr. EHRA also provided program management, drainage analysis and design, traffic engineering, environmental documentation and schematic design for the roadway, as well as grade separation at the Loop 494/UPRR railroad crossing.
EHRA conducted traffic operations and access management studies for the Northpark Dr. corridor. This corridor is approximately 2.2 miles long and has major signalized and unsignalized intersections and driveways that access various subdivisions and industrial developments. These studies laid the groundwork for the widening of Northpark Dr. from a four-lane boulevard cross-section to a six-lane boulevard complete street. The new street design includes low impact development drainage, conventional drainage, a grade separation at the UPRR crossing with mechanically stabilized earth retaining walls, two at-grade crossings for bi-directional frontage access, reconstruction of two concrete bridges over a diversion channel, intersection improvements, a roadway-adjacent multiuse path and traffic signal improvements.
Drainage analysis and design included hydrologic and hydraulic studies of both existing and proposed conditions to demonstrate that proposed project components would not adversely affect the 100-year floodplain in the area. The roadway and traffic designs contained horizontal and vertical alignments, cross-sections, plan and profile, sidewalk and bicycle accommodations, intersection layouts, traffic control plans and signing and pavement markings.
As the program management firm, EHRA coordinated with TxDOT, UPRR, the City of Houston Council District E, COH Planning and Development Department, COH Public Works and Engineering Department, Montgomery County, Harris County, HCFCD and area residents throughout the project.
A lighthearted guide to understanding your colleagues from another planet.
As a planner working among engineers, I sometimes feel like I’m speaking an entirely different language, and not just because I struggle with runoff coefficients or load-bearing calculations. As the title of this reflection suggests, engineers and planners tend to approach problem solving from far away starting places. How far, you might be wondering? Well, I’m not talking about a galaxy far, far away—maybe just a planetary system or two at most. But a small difference in perspective can lead to big differences in how we prioritize tasks, communicate with clients and ultimately how we define success.
Most readers will be familiar with the popular 1990s book, Men Are from Mars, Women Are from Venus. Even if you haven’t read it, the theme is obvious: Men and women have fundamental differences in the way they communicate, what motivates them, how they deal with stress and so forth. While the central idea of the book is generally true as a pattern and not universally true for every individual (my disclaimer), understanding how men and women tend to think, react and behave is undoubtedly helpful knowledge, especially for the men.
So too it is important to understand the tendencies of planners and engineers. Many of the differences are obvious when we stop to think about them, but we lead busy professional lives and there’s not always time between back-to-back meetings and end-of-day deadlines to analyze what we just heard in the previous weekly meeting. What follows are not universals, but helpful reminders for navigating your next encounter with an extraterrestrial—or an Earthling (for our Martian readers out there). And before you ask, “Hey! What about the landscape architects, surveyors and construction guys?” I think it is safe to group the landscape architects with the planners, and the construction guys with the engineers, generally. But the surveyors are a totally different breed that we are all still trying to figure out.
Planners tend to be visionaries. We begin with the end in mind. And even though many of us have been trained in code writing and precise technical drafting, the vision is what motivates what we do, especially when it comes to neighborhoods. We imagine vibrant communities, walkable streets and public spaces that bring people together. We see our plans more as works of art rather than blueprints. That centerline radius of 547.8’ might be the perfect curve to align the entry drive with the rec center and we don’t want the surveyors to change it (on second thought, I might know what planet the surveyors are from). Knowing that aesthetic change may cost a little extra, no one is more determined than a planner to make it work within the budget. Doing what it takes to create the best place to live is what we, as one team, are focused on. Admittedly, a planner’s passion can have unintended consequences or additional challenges, but it’s important that engineers understand where we are coming from and why we value so greatly the things we do.
While planners start off thinking pie-in-the-sky, engineers meanwhile keep us grounded, literally. As realists, they tend to think in terms of cubic feet of dirt, cut and fill and side slope percentages—all crucial components to creating livable and functional places to live. The first time they review a bubble plan, their minds are filled with calculations, code requirements and the cost implications of every single line drawn. It’s not uncommon for a planner to get the first markup back from the engineering team and die a little inside when the Water Plant and Wastewater Treatment Facilities have basically become the entry features for Phase 1 (from the planner’s perspective). But as someone reminded me once, the toilets have to flush. However, planners will continue to ask if we can run water uphill. Just once.
You might think that the engineer’s respect for and strict adherence to the laws of gravity would earn them the honor of being considered the earthling in my analogy, but ultimately, I think that title belongs to the planners, who stubbornly ask themselves the question “what will a person experience” each time they design a new place.
In the end, planners may be from Earth and engineers from Mars, but the real magic happens when those worlds collide. We may speak different languages, but together, we build something far greater than the sum of our parts. As a true multidisciplinary firm, the EHRA team brings the full galaxy of ideas to the table: grounded creativity, structured imagination and a shared mission to deliver the best solutions to the communities we serve. Solutions that are as visionary as they are viable. Because when Earth and Mars team up? That’s when real innovation launches.
