Elementary Sensory Pathway

Priorities: – Sensory Engagement – Child Safety – Nature Connection – Educational Experience
Challenges: – Maximizing Learning Potential – Utilizing Limited Space
Solutions: – Sensory Pathway Design – Natural Material Selection – Careful Element Placement – Native Plant Integration

Maas Verde partnered with Austin ISD to bring the district’s vision to life: creating the premier model for nature play in the United States. Our collaboration resulted in an innovative sensory pathway that redefines outdoor learning spaces for children. More than just a surface to run across, this pathway is designed to inspire observation and exploration through sight, touch, hearing, and smell. It transforms a simple walkway into an immersive educational environment that fosters a deep connection with nature.

Our approach goes beyond constructing a path. Each 3’x3′ section of the pathway offers a mini sensory adventure, incorporating materials like textured tree cookies, diverse rock and gravel arrangements, and native plants. Crunchy gravel, smooth and shiny stones, fragrant herbs, straight lines, and spirals combine to create a dynamic and interactive experience. These elements spark curiosity and invite hands-on exploration, making the sensory pathway a standout feature of the courtyard.

Safety was our top priority throughout the design process. Materials were carefully embedded to prevent shifting, non-irritating plants were selected, and the layout was designed to minimize tripping hazards. Every detail ensures children can explore freely and safely.

Sustainability was also key. By repurposing materials from the school and choosing native, low-water plants, we reduced waste and supported the local ecosystem. Surrounding garden beds further enhance the sensory experience, featuring fragrant and tactile plantings. Textural interest and “brush-by” fragrances extend the sensory engagement beyond the path itself. By favoring native species, we have taken the first step in ensuring that the plants are water wise and very tough – essential in a children’s play area!

This project is more than a landscape upgrade; it’s a model for interactive outdoor learning. By blending thoughtful design, educational intent, and ecological mindfulness, we’ve created a space where children can play, learn, and build lasting connections with nature. Maas Verde and Austin ISD are proud to offer a blueprint for schools looking to enrich outdoor education through sensory engagement.

 

 

Expedited Cafe Hardscape Fixes Slip Hazard

Priorities: Walkway Safety Hazard – Reduce Pressure on Heritage OakChallenges: Tight Scheduling – Balance Elements of Hardscape and SoftscapeSolutions: Task Orientation – Detailed Grading

Live in Austin long enough, and you’re bound to lounge on the shady patio at Better Half Coffee & Cocktails.

The spread itself is broad and welcoming, and the live oak that shades it has been there far longer than any of us have been alive. As the holidays approached in 2022, both the hardscaping and the heritage tree needed some care.

Better Half turned to Maas Verde to fix a sloping stone walkway that had become a safety hazard. The path was too narrow to allow two-way foot traffic, and the granite gravel it was bedded in had started to exfoliate onto the stones.

A stone walkway with exfoliating gravelMessy gravel created slip-and-fall hazards.

Slip-and-fall incidents became too common as customers and staff jockeyed around each other on the tricky slope.

However, the fix wouldn’t be as simple as mortaring in a walkway. Specifications from a City of Austin arborist dictated no impervious surfaces could cover the tree’s root mass. Recently decompacted via air spading, the area must now remain open to water absorption, and resilient to foot traffic.

Finally, Maas Verde faced a scheduling challenge. Cooler temperatures and holiday crowds meant busy days were getting busier, and the restaurant would soon place its permanent winter tents on the patio.

“In every aspect, the project not only addressed aesthetic problems, but functional ones,” Maas Verde founder and president Ted Maas explained. “This eroding slope ended in an asphalt cake, and the granite gravel created a slip hazard. We needed to put in a patio that would secure all that, handle heavy traffic, and float on top of the tree roots with no excavation.”

Maas Verde met the parameters by resetting the existing stone on a decomposed granite bed, then adding a second row.

Grading the decomposed granite below the stone surfaces, and then coating it with a non-toxic stabilizer, limits its tendency to dislodge.

At the bottom, Maas Verde placed a cut limestone step to provide retention and maintain the overall grade.

Maas Verde worked efficiently to get out of the way of the tent install crew. Project manager John Harris visited the site for a final walkthrough days later, after the tent crew had started work.

“It wouldn’t have been impossible to do this job with those guys there at the same time,” he said, pausing. “But it would have been close to it. They were working right on top of our job site — which was also an early test of concept.”

Better Half said the walkway has made the courtyard safer, and reported no further slip and fall incidents as of this writing.

Land Clearing for Future Work Retreat

Priorities: Remove Dense Brush – Treat for Prevention
Challenges: Tight Corridors – Trip Hazards – Pollution
Solutions: Safety Focus – Teamwork Between Operators and Ground Crew

Supervisory staff at a Central Texas farm supply company had big plans for a 4-acre swath of undeveloped land at its corporate headquarters. But the parcel would need a lot of work first.

The land was choked with invasives like ligustrum (L. lucidum), Chinaberry (Melia azedarach), and Chinese tallow (Triadica sebifera). Vines climbed into taller trees in thick curtains. And the site’s close proximity to a major highway, a set of railroad tracks, and a retention lake had led to persistent unsanctioned camping and trash problems.

Plans existed for the site to become a “retreat,” where the company’s corporate staff could take relaxing work breaks in the form of meditation, yoga, and outdoor lunches.

The scope of work included removing and herbiciding invasives, then mowing the remaining brush and limbing trees up to eight feet high to clear the understory.

Safe Implementation

Maas Verde first assessed objective hazards. Trash, both visible and hidden among the thick brush, was an injury and/or disease risk. Narrow corridors meant operators couldn’t drive machines through some areas — and that in others, they would have to work closely alongside the ground crew. Chainsaw operators needed to remain cognizant of trip hazards in between cuts. And a barbed wire fence cut through the middle of the work area.

Key equipment included two skid steers, one mounted with a grapple bucket and one with a forestry mower. The ground crew used chainsaws and backpack sprayers.

The crew cleared the land to spec safely and methodically. Once the ground crew swept an area, the machine with the grapple bucket removed piles of downed brush. The forestry mower then removed remaining vegetation and mulched the area.

Andy Maas, who managed the project for Maas Verde, explained the team’s approach.

“Cutting the unwanted brush and treating those cuts was the main priority. We also thinned a lot of the vines,” Maas said. “This site was so overgrown, and some of the work areas were very challenging. To finish the job without any safety issues was our goal, and we accomplished that.”

Maas Verde hauled off remaining material that couldn’t be mulched, concluding all scopes of work.

Natural Playground Design/Build

Priorities: Safe Landscaping For All Ages – Engaging Natural Play StructuresChallenges: Poor Drainage – Tight Safety ConstraintsSolutions: Deep Excavation – Expert Auditing – Creative Design Choices

St. George’s Episcopal School needed a long-planned playground rebuild. The existing grounds covered over two acres, but did little to add learning or play opportunities for the school’s young students. Outdated play fixtures and degraded surfaces were the general rule.

The school’s lead administrator, Jerri Thompson, has a career-long early childhood development background with a specialty focus on natural play. A natural playground focuses around play structures built with elements and textures from the earth, instead of plastic or steel.

In concept, natural playground designers create safety-compliant equipment and play areas with components like logs and stumps, boulders, plants, and mixed, natural surface materials. That’s exactly what Thompson and St. George’s wanted.

Design/Build

Maas Verde tasked its in-house playground designer, Marc Opperman, on the project. Opperman brought over a decade of natural playground design experience to the job. He had also developed some familiarity with the site itself by creating previous partial designs for the space.

Maas Verde began deep excavation work in early April, and worked on site daily for the next eight weeks. The final install includes log-and-lumber pergolas, log climbing structures, lawns and drainage swales, multiple new trees, shrubs, and planting areas, and even fountains — all of which meet playground safety regulations.

The space breaks down into four main areas: three playgrounds designed for students in different age brackets, and an entryway area with a fountain and some sculpture installations.

Maas Verde measured out prescribed fall zones for play structures including climbing equipment and swingsets. Opperman chose natural materials instead of synthetic options in all applications. Borders between walkways and play pits are Juniper logs instead of segmented plastic edging. And vertical structures like the logs for climbing (fitted with real, commercial-grade resin climbing holds) are edge-chamfered for safety. Ground surfaces like mulches and pea gravel can break a fall but still create a consequence.

Two cambered “race tracks” function the same way. Toddlers and infants race toy vehicles down the slopes, honing their spatial reasoning. Runout zones are grass and mulch berms.

Artificial surfaces and exhausted fixtures came out, improving safety and updating appearance. Maas Verde removed astroturf and rubber bumpers surrounding a playscape, then replaced it with a mulch bed and the site’s signature log borders.

An existing shade sail had failed, so Maas Verde tore it out and installed a pergola. And bright white play sand replaced gritty aggregates in play pits.

Challenges and Outcomes

Hidden obstacles included hundreds of square feet of unexpected concrete and asphalt buried deep below the existing turf. Deeper excavation was the only option.

A drainage flaw surfaced during one heavy rain. Water pooled on the playground surface and backflowed toward the main school complex. Maas Verde redrew plans to build in a grassy swale that would redirect the water back toward absorbent areas of the playground.

A previously installed, 25-foot-long creek runs on a solar-powered pump. The feature is a design centerpiece, but requires maintenance: heavy weeding and marginal drainage are concerns. Per Thompson’s priorities, Maas Verde will adopt the creek along with its ongoing maintenance plan.

Carefully-chosen plantings complete the design. Plants should be visually stimulating but tough enough to survive inquisitive toddlers.

“For me, this is the vision of my entire career,” Thompson said. “Schools are clamoring to install things like these, and you can see why.”

Opperman summed up the transformation: “Before we started, it had the feel of something made in the ‘70s — it was kind of neglected. Now, it’s not only updated but it’s got natural materials and passes safety compliance.”

Preschool Playground Refresh and Reconfigure

Project Description:

This North Austin Preschool wanted to redesign and refresh the landscape around their playground. The old playground had rotting timber log borders and uneven loose gravel. Maas Verde was called in to redesign the layout of the landscape using new cedar logs and refreshing most of the area with kid-friendly mulch for safety.

The work consisted on removing a spiral feature on the existing play set, removing, and disposing of existing wood border, replacing wood border with cedar logs and bringing the borders inward by a couple feet, creating two gravel islands; one for the swing set and one for the play set area and mulching the areas around the cedar log border and in the play area adjacent to the swing set.

San Gabriel Unitarian Universalist Fellowship

Project Description:

Founded in 2007 San Gabriel UU Fellowship is comprised of people of many beliefs and backgrounds. Located near the heart of historic Old Town across the street from Southwestern University in Georgetown, Texas, their building is both traditional and contemporary, and it reflects their commitment to the inclusion of people of all ages, abilities, and mobility.

Maas Verde Landscape Restoration was engaged to construct a concrete sidewalk, French drain system, and a large deck. The deck and sidewalk had to meet perfectly, so the Maas Verde team ensured that the grading and elevation were perfect. The construction area was prone to flooding during heavy rain, requiring a creative approach to ensure the project’s success.

The amount of water coming down from two different off-site parking lots from other churches was a significant issue. In order to accommodate rainfall during construction, the team manufactured a custom concrete drain box that was capable of taking on a significant amount of water. The French drain was designed and installed with a high capacity for stormwater, and the Maas Verde team constructed two rain gardens downstream of the deck to slow the water down at various points.This innovative addition allows for water to seep into the ground and lessens the load on the drainage system. By mitigating impervious cover and creating natural catchment areas for the rainfall, the team able to design with nature in mind and provide an effective sidewalk and landscape solution. The sidewalk met ADA compliance and a ramp was constructed to provide ease of access for everyone. This custom French drain box (24″^3) was fabricated off-site.
