Environmental Specialties

Environmental compliance is interdisciplinary by nature.

Environmental services are inherently multidisciplinary. A diversity of professional perspectives in environmental analysis is valuable. Most often, driven by project location, context, characteristics, resource sensitivities, and level of controversy, the focus needs to encompass multiple study elements. In such instances, professionals with a range of technical expertise conduct research, collect and analyze data, and prepare special studies, respond to controversy, and/or support consideration of project approval. The Ascent team offers the broad spectrum of technical fields needed to support the environmental decision-making and permitting process. We work collaboratively with our clients and stakeholders to understand their goals, challenges, and opportunities and to deliver innovative and sustainable outcomes.

ENVIRONMENTAL KNOWLEDGE
Task Force Shares Information on Governor’s Emergency Proclamation to Expedite Fire Fuel Treatments

On March 1, 2025, Governor Newsom proclaimed a State of Emergency to expedite implementation of fire fuel treatment projects. Among other provisions, the Proclamation directs the suspension of certain “statutes, rules, regulations, and requirements” for projects subject to approval by departments of the California Natural Resources Agency and the California Environmental Protection Agency for “critical fuel reduction projects” that are “initiated this calendar year.” It also called for the immediate update of the California Vegetation Treatment Program EIR to increase its usefulness and efficiency for “promoting rapid environmental review for large wildfire risk reduction treatments.” At its Regional Meeting in Marin County on March 27, 2025, the California Wildfire and Forest Resilience Task Force released more information to explain how CNRA and CalEPA will execute this directive.

CEQA Considerations for Community Wildfire Protection Plans

Community Wildfire Protection Plans (CWPPs) focus on reducing wildfire risk to people, homes, businesses, watersheds, cultural resources, infrastructure, natural ecosystems, and other values or resources within the community. CWPPs are collaboratively developed by local, state, federal and tribal partners, such as emergency responders, FireSafe Councils, local planning staff, and state or federal resource agencies. The California CWPP Toolkit, a great new resource, has been launched by the state. It is a free online resource containing a comprehensive guide, customizable template, best practices, and additional resources to help communities develop and implement effective CWPPs.
