Tijuana River Valley Needs and
Opportunities Assessment (NOA) Report
The Tijuana River Valley Needs and Opportunities Assessment (NOA) Report provides a comprehensive review and assessment of potential management strategies to address transboundary flows of sewage, trash, and sediment into the Tijuana River Valley located within the United States (U.S.). The NOA Report is intended to provide information and guide decisions on the future implementation of projects to reduce impacts on the Tijuana River Valley from the transboundary flows. The NOA Report includes an analysis of existing transboundary flow water quality conditions and management practices, a needs assessment and data gap analysis, potential proposed projects, evaluation of proposed project alternatives benefits and costs, and project recommendations.
