Insights

Small but specialized RSA+ operates with 11-50 employees and focuses on civil engineering and surveying for niche sectors such as wineries, resorts, hotels, residential, and permitting. This presents opportunities for targeted outreach to boutique developers, boutique hospitality projects, and wine country developments that require specialized surveying and code compliance expertise.

Regional focus Serving Northern California since 1980 positions RSA+ as a seasoned local partner with deep regulatory and permitting knowledge. Sales teams can leverage this for introductions to regional developers, municipalities, and project owners seeking trusted local consultants for complex permitting and wastewater projects.

Tech-forward RSA+ highlights a flexible approach with involvement in modern technologies and a tech stack including WordPress, Google Maps, and standard web tools.

Revenue signal With annual revenue in the 1–10 million range, RSA+ is a mid-market player capable of handling mid-to-large scale projects while maintaining personalized service. Growth conversations could focus on expanding multi-site resort, winery, or residential development projects and entering longer-term retainer relationships for ongoing permitting and compliance work.

Strategic partnerships As part of the RSA+ family of companies and a proven track record in planning, permitting, and code compliance, there is an opportunity to cross-sell or partner with larger engineering firms seeking regional complementors for Northern California projects, or to position RSA+ as a preferred subcontractor for integrated civil engineering and surveying scopes.
