Catalyst, as a subcontractor to Brown and Caldwell, is providing regulatory assistance and CEQA compliance for this important multi-modal transportation project. Catalyst is leading the environmental review of this important community project. As the greenway network is currently under design development, Catalyst developed a regulatory constraints analysis for proposed segments, as a GIS layer, to assist the team in identifying the most optimal routes. Key considerations include proposed trails along flood channels, and within the jurisdictional boundaries of waterways, which could trigger Clean Water Act Section 401, 404 and/or 408 permits. Once the final design alternatives are completed, Catalyst will prepare an Environmental Impact Report (EIR) for the proposed project.
