Environmental Planning

GZA’s planning team draws upon decades of experience to develop effective strategies for clients to proactively address potential liabilities that may arise during the environmental review process. Our wide-ranging experience includes preparing environmental documents for all types of projects for public and private sector clients throughout the country. 

We assist clients in preparing legally defensible environmental impact assessments related to federal, state, and municipal environmental regulations including NEPA, CEQR, SEQR, MEPA, and CEPA.  We recognize that projects are typically time sensitive and GZA can quickly draw upon our in-house resources to seamlessly guide clients through the review process including project planning; hazardous materials remediation; site/civil and geotechnical engineering; wetlands delineation and permitting; and noise and air quality studies to get your project completed as quickly and efficiently as possible. 

Our environmental planning projects include commercial and residential developments, infrastructure, and transportation projects throughout the country.

Through decades of experience, our zoning professionals regularly recognize, anticipate, and resolve issues early on by coordinating with stakeholders. 


We regularly work with our clients’ legal counsel and architects to develop solutions and get projects approved. Our expertise in land use matters enables us to suggest and evaluate project alternatives and manage applications for municipal zoning and planning boards as well as state, county, and regional authorities for site plan approvals, permits, zoning variances, rezoning requests and special permits.  We also assist clients with state liquor authority and state cannabis license applications.

Acoustics, Noise, Vibration and Air Quality

GZA is a recognized industry leader in acoustic, noise, and vibration consulting services. Our experienced professionals—Institute of Noise Control Engineering (INCE) members and certified by multiple states and cities—support a wide range of projects and deploy a full suite of state-of-the-art noise monitoring equipment and modeling software.

Noise-related issues are an ever-growing concern as industrial, commercial, and transportation sources are located near residential and other noise sensitive
areas. Our experts conduct noise monitoring programs to establish ambient background levels at sensitive receptor locations. For example, we determine noise levels from equipment located at industrial and commercial facilities and from transportation systems (roads, highways, rail lines, airports). We also conduct noise modeling impact analyses. Based on the monitoring programs, modeling, and impact assessments, GZA can make recommendations for mitigation alternatives such as barriers, sound insulation or other design modifications to keep impacts to noise sensitive areas below federal, state, and local criteria levels. 

GZA’s background in both technical and planning/land/zoning aspects of these projects gives us a unique perspective to develop effective solutions.

GZA has the experience necessary to plan effective air compliance and permitting strategies all while successfully negotiating with regulatory agencies. Many of the nation’s most significant environmental regulations have been catalyzed by growing concerns about air quality. GZA completes both Title V and New Source Review permit applications, performs air quality impact analyses, and conducts air pollution control technology evaluations to address these concerns. 

We closely monitor state and federal regulatory changes, and use this knowledge, combined with our strong regulatory background, to advise clients on how these changes will impact their business.

GZA utilizes Esri’s industry-leading ArcGIS Platform and ArcGIS Enterprise to provide full integration with desktop, web, and mobile applications for data collection with real-time access and viewing. We employ geospatial data management in concert with our other services. We also assist our clients with using these applications and tools to seamlessly integrate information management into their operations and businesses.
