A rendering can make anything look good. The real question is how it actually performs. We don’t just design and talk about the outdoors; we get out there, experience it, and validate our decisions in the field.

If a designer is speaking about sustainability and site design but never leaves the desk, then the work stays theoretical.

Our team recently spent time at a nursery inventorying trees that are being contract-grown in advance of bidding for one of our projects. For large-scale work, this is standard practice. It also significantly increases the likelihood of high-quality, consistent plant stock making it into the ground, while preserving the original design intent.

When projects struggle with excessive plant substitutions, out-of-season installation, or premature planting that compromises long-term health, that’s often a sign the work is being driven more by theory than field experience.

Projects, especially those heavily focused on site design and delivery, benefit from leadership that understands how decisions hold up in real-world conditions. That’s where the landscape architect plays a critical role as the architect of the site.

That’s where the work gets tested.

Even when ideas are abundant, brownfield work often stalls when pathways are not clear.

That was a recurring thread at this year’s Virginia Brownfields Conference.

SGA’s contributions focused on how projects actually move forward:
• Using GIS to organize complex site conditions into decision-ready insight
• Aligning land strategy with realistic redevelopment potential
• Identifying funding routes early enough to shape outcomes

Tim and Alison explored how spatial data becomes a working tool, not just a map. Across sessions, a consistent theme emerged: progress comes from connecting information, funding, and design early, before a site is boxed into limitations.

Thank you to Virginia DEQ for creating a forum where implementation-focused conversations can happen.

Professional licensure is what connects design decisions to public responsibility.

June 10th is ASLA Advocacy Day, led by the American Society of Landscape Architects, recognizing the role landscape architects play in shaping policy, standards, and the built environment.

Landscape architecture sits at the intersection of planning, ecology, engineering, and urban design: where decisions directly affect how communities function, perform, and adapt over time.

Licensure ensures professionals are trained and tested in protecting public health, safety, and welfare as it relates to land use, environmental systems, and the public realm.

For us, that responsibility is foundational. Our work is led by licensed professionals across multiple states, applying consistent standards that guide environmental performance, accessibility, and long-term stewardship of land and infrastructure.

Members of our team have participated in ASLA Virginia advocacy efforts over time in support of licensure and professional standards that protect the public interest, while founding partner Tim Stromberg serves on Virginia’s APELSCIDLA board through DPOR, advancing oversight that strengthens trust in the design professions.

Proud to support Advocacy Day and the continued role of licensed professionals in advancing resilient, well-functioning communities.

This week, our team is attending the Virginia Brownfields Conference hosted by the Virginia Department of Environmental Quality (VADEQ) in the historic City of Staunton, VA. This annual conference brings together government officials, city planners, developers, real estate professionals, and environmental consultants from across the state for a 3-day program focused on brownfield redevelopment.

At the conference, we’re sharing how communities can leverage brownfields planning tools to unlock funding opportunities and navigate remediation programs, turning underutilized properties into viable assets. We also demonstrated digital inventory tools that help prioritize sites and support strategic redevelopment decisions.

We are excited to be collaborating with this wide range of professionals and to continue advancing practical, implementation-focused approaches to brownfield revitalization across Virginia.

As part of Norfolk Academy’s Maymester program, students spent time at the Ryan Resilience Lab exploring how design, science, and community leadership come together to address coastal resilience in real time.

Walking the site together, the conversation moved beyond theory into how living shorelines function, how access shapes understanding, and how design can make complex environmental systems legible and engaging.

At SGA, that translation is central to our work: creating landscapes that don’t just perform, but communicate.

Grateful to share the experience alongside collaborators at WPA and Wetlands Watch, and to the Elizabeth River Project for the vision that made this place possible.

Trails, cities, stories, and a strong case for 80s movies: Lev Najarian brings a little bit of all of the above to SGA.

Lev joins SGA as a Project Planning Intern. He is currently a graduate student in urban and environmental planning at the University of Virginia, with a background that spans trail construction and documentary filmmaking.

That mix gives Lev a grounded, human-centered perspective on urban planning and design. He is especially interested in advancing trail development and nature-based infrastructure as tools for urban connectivity and more accessible green space.

Outside of planning work, Lev enjoys running, playing tennis, playing the drums, and watching 80s movies.

We’re excited to welcome Lev to the SGA team!

A good plan looks ahead. Eric Willersdorf also knows the value of looking back.

Eric joins SGA as a Project Planner, bringing a background in preservation and environmental planning to his work. With an “eye to the past,” he approaches projects with a thoughtful understanding of history, place, and the communities shaped by both.

Eric attended the University of Virginia, earning a Bachelor of Urban and Environmental Planning with a second major in History and a minor in Architectural History in 2025. He returned to Charlottesville this past August to pursue his Master of Urban and Environmental Planning.

His passion for public service grew through his planning education and his time with the National Park Service. Eric continues to guide his focus on community engagement, environmental stewardship, and the integration of public history into planning work.

Outside the office, Eric enjoys visiting Virginia’s state parks, collecting antiquarian maps of Virginia, and playing bass guitar.

Welcome to SGA, Eric! We’re excited to have your perspective on the team.

Julia joins SGA as a Landscape Designer Intern this summer from the University of Georgia, where she is pursuing a Bachelor of Landscape Architecture with a certificate in sustainability and entrepreneurship.

Her studies have sparked a passion for designing thoughtful, resilient landscapes that strengthen the connection between people and place, a perspective we’re excited to see in action.

Outside the studio, Julia enjoys tennis, running, creating art, and hosting dinner nights that are equal parts cooking and chaos. She also draws inspiration from travel.

Welcome to SGA, Julia!
