Natural resource solutions.

Managing natural resources in a changing world requires foresight, technical depth, and a partner who understands the full picture. Trihydro’s engineers, scientists, and planners collaborate directly with clients to tackle challenges like water scarcity, post-fire recovery, and habitat degradation. From watershed planning and stream restoration to groundwater modeling and comprehensive ecological assessments, we provide integrated, science-based strategies tailored to each project’s goals. Our work blends regulatory insight with practical field experience to deliver sustainable, measurable outcomes—always guided by a commitment to environmental stewardship and long-term resource resilience.

Environmental Planning

Development projects often overlap with sensitive natural resources like land, water, and wildlife, requiring a clear understanding of ecological systems, regulatory frameworks, and on-the-ground conditions to comply with environmental regulations. Trihydro combines the expertise of biologists, ecologists, environmental planners, and environmental permitting specialists to help our clients navigate environmental review, regulatory compliance and permitting, and natural resource management. Our integrated approach supports our clients’ interests in identifying constraints, reducing risks, meeting obligations, and balancing development with ecological stewardship.

Permitting and Compliance

With decades of expertise, Trihydro helps clients secure environmental permits across federal, state, and local frameworks while supporting environmental compliance. Our team understands the permitting processes under key laws such as the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the National Environmental Policy Act, enabling us to anticipate challenges, streamline applications, and effectively engage with regulatory agencies. Beyond environmental permitting, Trihydro develops and implements tailored environmental compliance management programs to meet environmental regulatory obligations. This includes monitoring, reporting, auditing, and training supported by our multidisciplinary team of scientists, engineers, and regulatory experts. Whether addressing air emissions, water discharges, waste protocols, or site remediation, our proactive, integrated approach helps clients minimize risk, maintain operational continuity, and align with environmental goals.

Stormwater Management

Stormwater can carry harmful pollutants from roads, parking lots, and other surfaces into natural waterways, posing risks to public health and the environment. To address this, the Clean Water Act (CWA) and related state and federal regulations require many facilities, municipalities, and regulated sites to implement stormwater management strategies. These may include Stormwater Pollution Prevention Plans (SWPPPs), Stormwater Management Programs (SWMPs), Best Management Practices (BMPs), and routine inspections or audits. Trihydro offers comprehensive stormwater management services designed to reduce pollutants, control runoff volume, and facilitate regulatory compliance. With specialized knowledge in runoff treatment, monitoring, and documentation, our team supports diverse projects spanning energy infrastructure, industrial operations, commercial properties, and residential developments.

Water Resources

Effective planning and management of water resources are vital for optimizing systems and maximizing the use of available supplies to meet diverse and often competing needs ranging from ecosystems and agriculture to municipal and industrial demands. Understanding how to efficiently use, reuse, and protect this finite resource is fundamental to sustaining life and supporting economic prosperity. Trihydro offers comprehensive expertise across the primary hydrologic cycle processes, promoting the coordinated development and management of water, land, and related resources. Our team of engineers, geologists, and scientists have a thorough understanding of surface water and groundwater systems. We apply practical methods in planning and management, hydrology, hydraulics, and permitting and compliance to meet the societal and environmental needs of our clients.
