Welcome to Atzl, Nasher, and Zigler, PC (ANZ), a leader in surveying, site planning, and civil engineering since 1968.

For over five decades, we’ve combined pioneering expertise with an ever-evolving team of top-tier engineers. Our specialties span stormwater and wastewater engineering, land development planning, and in-depth knowledge of New York City’s rigorous stormwater regulations.

Beyond our core services, we serve as a critical resource for architects, offering expert guidance in specialized areas like stormwater construction management—bridging the gap where licensing limitations apply. Our deep proficiency in industry standards such as SWMP (Storm Water Management Program), SMP (Storm Water Pollution Prevention Plan), and SWPPP (Storm Water Pollution Prevention Plan) ensures seamless project execution.

Unlike the majority of engineers who focus on structural (80%) or transportation (18%) engineering, ANZ stands out in the highly specialized field of water resource engineering—an area where only 2% of engineers operate.

At ANZ, we are committed to delivering superior quality, innovative solutions, and unmatched client service. Explore the expertise that sets us apart and discover how we continue to push boundaries, set industry benchmarks, and redefine excellence in surveying, site planning, and civil engineering.
