What Houseal Lavigne Associates does

Houseal Lavigne Associates is a privately held urban planning and geospatial design firm founded in 2004 and headquartered in Chicago, Illinois, with additional regional offices in Los Angeles and Seattle. The firm serves U.S. municipal governments (cities, villages, towns, and counties) across four integrated service lines: Community Planning & Urban Design (comprehensive plans, corridor studies, downtown and subarea plans), GIS & Geospatial Services (Esri ArcGIS implementation, data management, web mapping, geospatial analysis), Zoning & Development Regulations (ordinance rewrites, form-based codes, subdivision regulations), and Digital Twin & Visualization (Esri CityEngine procedural modeling and game-engine-based 3D environments). Its technology stack is built on the Esri ArcGIS platform — including ArcGIS Pro, ArcGIS Urban, ArcGIS Enterprise, ArcGIS Online, CityEngine, Hub, Business Analyst, ArcGIS Insights, and Survey 1-2-3 — over which it layers a branded AI product, EuclidHL, launched in March 2025 as an AI+GIS powered planning and zoning assistant that returns text, map, and graphic answers to natural-language municipal queries and claims to deflect roughly 95% of incoming planning inquiries.

The firm operates as an Esri Gold Partner holding ArcGIS Online Specialty, ArcGIS Urban Specialty, and Release Ready Certifications, making it one of a small number of U.S. urban planning consultancies with the ArcGIS Urban designation. Revenue is generated through project-based professional services engagements with custom, quote-based pricing; engagements are initiated via direct outreach, the firm's website, and a recurring webinar series that functions as both thought leadership and demand generation. Its go-to-market is business-to-government field sales supplemented by American Planning Association conference participation and YouTube-distributed webinars, with no reseller or marketplace channel. The leadership team is composed of FAICP-credentialed co-founders John Houseal and Devin Lavigne, plus AICP-credentialed practice leads across Planning, Zoning, and GIS, and a dedicated business development lead, signaling a credentialed, partner-led delivery model targeting public-sector procurement.

The firm's most significant strategic pivot is the 2025 launch of EuclidHL, which sits atop its consulting services and signals an intent to productize a portion of the business into a reusable, multi-municipality AI asset. The combination of named credentials, top-tier Esri partner status, an AI-augmented product layer, and a three-office geographic footprint represents the firm's principal competitive position; the principal risks are dependency on the Esri platform, the absence of disclosed revenue or funding, and the lumpiness inherent to project-based municipal procurement.

Core offering

Houseal Lavigne Associates delivers project-based professional consulting services in community planning, urban design, GIS/geospatial analysis, zoning and development regulations, and digital twin visualization to municipal and public-sector clients across the United States. Layered on top of these consulting services is EuclidHL, an AI+GIS powered planning and zoning assistant the firm offers to help municipalities answer resident and staff queries about zoning and planning data 24/7.

Product overview

Houseal Lavigne Associates is a single, unified urban planning and geospatial design firm organized around four core service lines—Community Planning & Urban Design, GIS & Geospatial Services, Zoning & Development Regulations, and Digital Twin & Visualization—that together feed a flagship AI product, EuclidHL, described as an "AI+GIS Powered Planning and Zoning Assistant." The firm operates as an Esri Gold Partner and layers these services into a platform-plus-modules architecture in which the GIS service line and the Digital Twin service line provide the geospatial and visualization backbone, the Zoning service line provides the regulatory data, and EuclidHL sits on top as the AI-driven customer-facing interface that turns those planning and zoning datasets into conversational, text-plus-map-plus-graphic answers for residents, businesses, developers, and city staff.
