About Us

Horizon Water and Environment, LLC (Horizon) is a multidisciplinary environmental consulting firm that specializes in watershed science, environmental permitting, CEQA compliance, and water resources management.  We have technical expertise in hydrology, geomorphology, water quality, water rights, wetlands, habitat conservation and restoration.  We are experts in CEQA/NEPA, environmental laws, and regulatory requirements.   We take pride in producing clearly written and legally defensible environmental compliance documents.  We specialize in using our technical experience, regulatory expertise, and exceptional communication and project management skills to successfully obtain federal, state, and local permits for our client’s projects.  We are recognized leaders in developing environmentally sensitive ways to implement and maintain flood management and water supply projects, including the operation and maintenance of streams, channels, canals, reservoirs, basins, and other infrastructure.

Though our firm is relatively young, our professional experience is long-standing.  Principals Ken Schwarz, Ph.D. and Michael Stevenson, M.S., bring over 30 years of professional experience in environmental consulting with federal, state and local agencies as well as the private and nonprofit sectors.  We specialize in working with public organizations including water agencies, flood control districts, cities, and counties.  As a small but growing firm (currently 10 employees), we bring focused attention and dedication to all of our projects. We have enough staffing capacity to accomplish large projects with accelerated schedules.  Our work is guided by the following fundamental principles:

  • Principal level commitment to all projects
  • Careful listening and attention to client needs
  • Project solutions through innovation and creativity
  • Rigorous scientific and professional quality standards
  • Complete project organization and management
  • Honest and clear communications with clients and stakeholders

Our approach to developing environmental solutions is based on first understanding the natural, managed, or impacted system. This includes recognizing fundamental hydrologic and geomorphic processes while integrating key water quality, biology/habitat, soil, geology, and climatic considerations. From this basis, sustainable water, land management, or infrastructure approaches are sought that achieve client needs while also protecting natural resources. Our proven success with environmental compliance and permitting is built on this deep resource understanding and expertise with regulatory statutes and guidance. Behind all of our work lies a profound respect for the wisdom and beauty of the natural world and a shared responsibility for its protection.
