Stromberg/Garrigan & Associates

What Stromberg/Garrigan & Associates does

Stromberg/Garrigan & Associates, Inc. (SGA) is a privately held, multi-discipline landscape architecture and urban design firm founded in 2007 and headquartered in Pennsylvania with offices in the Philadelphia Metro area (Wyncote, PA), Pittsburgh / Western Pennsylvania, Norfolk, VA, and Virginia Beach, VA. The firm employs 15-20 professionals and operates as a professional services consultancy rather than a software or product company. SGA delivers six interconnected practice areas: Landscape Architecture Services (site civil design, permitting), Urban Design, Brownfields Reuse Planning, Parks, Recreation & Green Space, Resiliency / Green Infrastructure / Landscape Utilities (stormwater, MS4/TMDL compliance, climate adaptation), and Project Implementation Management (funding strategy, federal/state appropriation matchmaking). Its technology foundation rests on GIS-based spatial analysis, collaborative design methodologies, and proprietary approaches such as the first privately held rolling conservation easement in the U.S. (Ryan Resilience Lab) and floodable landscape design (Chrysler Museum Glass Studio).

SGA's revenue model is fee-for-service professional services delivered through direct government contracts, qualifications-based selection, RFP responses, and direct engagement. Pricing is not publicly disclosed and is scoped per project. The customer base is overwhelmingly public sector: local governments (City of Norfolk, Somerset Borough, City of Ranson WV, Carlisle Borough PA, City of Hopewell VA), regional planning entities (Westmoreland County Redevelopment Authority, Downriver Community Conference, Hampton Roads Planning District Commission), state and federal agencies (EPA Region 3 brownfields programs), with a smaller mix of enterprise clients (Chrysler Museum, Somerset Trust Company) and nonprofits (Elizabeth River Project). The firm reports more EPA-funded brownfields contracts in EPA Region 3 than any other firm and positions itself as a national leader in EPA Brownfields Area-Wide Plans.

The firm differentiates through deep regulatory and funding expertise: a formal partnership with Sustainable Strategies DC has helped clients secure more than $100 million in public funding for parks, brownfields redevelopment, and infrastructure projects. Notable project outcomes include the Carlisle Urban Redevelopment ($20M+ federal/state funding, $100M+ private investment, part of a $126M effort), Fairfax Boulevard in Ranson WV ($12M investment spurring $50M+ downtown redevelopment), the Norfolk Thrive waterfront area (100+ acres), and the Ryan Resilience Lab. Distribution is direct-to-client with no intermediaries; marketing relies on industry conference participation (ASLA, APA, National Brownfields Conference), the Field Notes blog, and public engagement charrettes. Awards include the 2023 Phoenix Award, 2024 Fast Company Innovation by Design finalist, 2020 VA ASLA Honor Award, 2017 AIA Honor Award, and 2013 Phoenix Award / People's Choice Award.
