The careful management of water resources is an important responsibility for local, state, and federal agencies. Rincon staff assists clients through the environmental regulatory process, from project initiation to construction. We strategically carryout projects with a focus on timely completion, cost effectiveness, strong project communication, and stakeholder management. Projects for which Rincon has provided environmental consulting support include distribution and storage facilities, flood control, watershed management, and waterway restoration.

Water Quality

Our team of water resources specialists consists of certified Qualified SWPPP Developers, Qualified SWPPP Practitioners, and Certified Inspectors of Sediment and Erosion Control. The water resources team at Rincon has expertise in monitoring water quality on project sites; writing Stormwater Pollution Prevention Plan (SWPPPs) for construction sites to receive NPDES permit coverage; consulting with government agencies to obtain permits; applying cost-effective, proven technologies to remediate waterborne contamination; and creating, restoring, or mitigating wetlands and riparian habitats.  For projects involving structural changes to address water quality, such storm drain improvements, we also conduct CEQA environmental review.

Water Supply

Rincon analyzes the CEQA-related environmental impacts of projects that would affect local water supplies, such as water treatments systems to remove contaminants from groundwater, replacements of mains and pipelines that convey drinking water, and water appropriations and diversions.  Where construction may affect biological resources, we can assess project sites for sensitive species and habitats.  Rincon’s expertise allows us to help our clients meet their current and future water needs by proving effective and workable solutions that meet the technical, regulatory, economic, and environmental challenges facing water managers.
