Principal + CEO

Laura Hansplant RLA, ASLA, LEED AP

Laura integrates social spaces, rainwater systems and plant communities to create meaningful places where each element mutually supports the whole site. Born in Canada, Laura studied at the University of Toronto and the Pennsylvania State University, where she received a Master’s in Landscape Architecture with a minor in ecology. She volunteers on the US Green Building Council’s Sustainable Sites Technical Advisory Board, where she participates in discussions advancing sustainable design. Through speaking engagements Laura has found a passion for inspiring professionals and students on innovative design. Outside the office, she spends her afternoons exploring the natural patterns of meadows and woodlands, searching for inspiration for her designs. In her test garden, Laura grows native plants, taking note of their character and durability to inform resilient landscape designs. When she can get away, Laura enjoys wilderness canoeing, camping, and hiking with her family.

Charlie Miller Founded Roofmeadow in 1997

Founder + Emeritus

Charlie Miller PE

Charlie formed Roofscapes, known as Roofmeadow and Studio Sustena, in 1997 to introduce green roof technology for urban stormwater management to the United States. A technical expert in the field, his influence continues inspires our constant exploration of new and better green roofing designs and strategies. Charlie has authored four of the six published ASTM green roof standard methods. Charlie’s interest and experience in water resources and environmental engineering began in the 1980’s when he focused his attention on best management practices (BMPs) for water resource management, including biofiltration systems, integrated landscape measures and constructed wetlands. Charlie earned his Master of Science in Civil Engineering and his Master of Science in Geology and Geophysics from the University of Utah; he also earned his Bachelor of Science in Chemistry from the College of William & Mary. He lives in Philadelphia with his wife Lyndall.

Join our team

Full – or Part-Time Civil Engineer

Context and fit 

Studio Sustena, an integrated site-design studio, seeks an entrepreneurial-minded, civil engineer with a passion for design-led problem solving to join our growing team. The ideal candidate will have a working knowledge of regional permitting processes and cross training in green infrastructure design, including green roofs and/or on-ground stormwater management systems.

Focused largely on campuses, urban-infill sites, and landscapes on structure, Studio Sustena champions an integrated approach to landscape architecture and civil engineering that boosts opportunities for distinctive placemaking and high-performance landscapes. We believe that blending these traditionally separate disciplines reduces scope overlap and gaps; fuels the creative process; fosters enthusiasm around collaborative problem-solving; and frees up budget for the inclusion of high-value landscape design.

We often encounter environments and conditions that are very different than in most conventional engineering projects.  We believe it is essential that our engineering approaches continue to adapt in order to solve specific problems and that we develop our approaches from engineering principles and hands-on experience.


Position Responsibilities 

Performance of the site-civil engineering scope in Philadelphia and surrounding municipalities, including conceptual site plans, grading, drainage, stormwater management, erosion & sediment control, and utility design.

  • Interpretation of zoning, municipal, and state codes to determine opportunities, limitations, and development strategies for the property.
  • Support the preparation of project proposals and manage project budgets.
  • Proficiency with AutoCAD LT or Civil 3D required. Experience with GIS and/or 3-D Visualization software is a plus.
  • Engineering analyses in support of landscape and green infrastructure design, including but not limited to:
    • Existing site analysis, including vegetation and soil assessment.
    • Spatial design, such as amenity space and pedestrian/vehicular movement. Experience with AutoTURN or similar program.
    • Stormwater calculations, including hydrologic modeling, with a focus on Green Stormwater Infrastructure (GSI).
    • GSI system design and details, including weir, manifold, and stormwater conveyance system design.
    • Irrigation design is a plus.
    • Media review/mix assessment. An understanding of soil science is a plus.
    • Simple structural assessments for retaining walls, ballasted edges, and similar site features (static stability problems and structure deformation under load).
    • Wind analysis for green roof designs (based on ANSI standards and application of first principles).
    • Tree stabilization using existing and new principles.
  • Collaboration on all phases of site design to maximize the experiential and spatial value of required site infrastructure, to optimize the permitting process, and to enhance stormwater management.
  • Review and technical assessment of in-progress site construction; facilitation of communications among design consultants and contractors, and preparation or supervision of construction-phase documents.

Openness to consider creative solutions and desire/curiosity to innovate.




  • Bachelor’s and/or master’s degree in civil engineering.
  • Engineer-in-Training (EIT) Required.
  • Professional Engineer (PE) registration preferred.
  • Construction and/or lab experience preferred.

This position is an exempt (salaried) full or part-time position with a competitive benefits package. Salary will be commensurate with experience. Studio Sustena is an equal opportunity employer; a diverse pool of applicants is sought. We are committed to growing and preserving an inclusive and engaged culture that welcomes and celebrates our differences.
