What Sive, Paget & Riesel does

Sive, Paget & Riesel P.C. (SPR) is a New York-based boutique law firm founded in 1960 by David Sive, an environmental law pioneer. The firm provides specialized legal services across ten practice areas: environmental impact review and permitting, hazardous substances remediation, environmental issues in transactions and real estate management, zoning and land use, offshore wind, litigation, construction, project finance, climate change and resiliency, and renewable energy. Its core technology is human expertise in complex environmental regulatory frameworks including SEQRA, CEQR, CERCLA, NEPA, and the Clean Water Act, supported by former federal and state prosecutors, former law clerks, and trained mediators and arbitrators. The firm also produces thought leadership through the SPRingBoard Environmental Law Podcast, blog, and publications.

SPR serves government agencies and municipalities (Port Authority of NY & NJ, MTA, NYSERDA, NYC EDC), real estate developers and property owners (Two Trees, Prologis, Thor Equities, Domino Sugar redevelopment), renewable energy developers and lenders (Equinor Wind, Generate Capital, Carlyle Power Partners), and institutional clients (American Museum of Natural History, Northwell Health, New York Yankees). Notable engagements include representation of Equinor on the 2+ GW Empire Wind 1 and 2 offshore wind projects, defense of MTA's congestion pricing program across nine federal actions, and counsel on Battery Park City and Financial District Seaport climate resiliency master plans. The firm operates as a private professional corporation, single-office (560 Lexington Avenue, Manhattan), with approximately 20-30 attorneys.

The business model is a traditional partner-led law firm charging on an hourly basis for legal services, with some fixed-fee and contingency arrangements for specific matters. Go-to-market is reputation, referral, and thought leadership driven rather than sales-led outbound; the firm does not disclose revenue, has no external investors or parent company, and has not pursued funding rounds. Pricing is quote-based on matter complexity and attorney seniority, and engagements are typically multi-year, reflecting the long-cycle nature of environmental permitting, litigation, and infrastructure work.

Direct peers

• Beveridge & Diamond: Beveridge & Diamond is one of the largest U.S. environmental law boutiques, with a national practice spanning environmental litigation, regulatory compliance, and transactional matters.

It is a direct peer in terms of boutique specialization, with comparable work in clean energy, environmental review, and natural resource regulation.
