Keeping with the Flow

McFarland-Johnson has established a strong track record during its years of providing water resources services to its clientele. Our team of diversely trained engineers and environmental scientists is able to provide a comprehensive range of services through our extensive project experience and available resources. Our staff takes pride in keeping abreast of state-of-the-art methods and innovative software available in the industry, and is committed to maintaining a high level of service in this competitive marketplace.

Our extensive experience includes hundreds of FEMA studies, bridge backwater studies, NPDES permitting projects, Phase I/II dam studies, and stormwater management and design projects. Our skilled staff can identify, analyze, and design effective and appropriate options on any water resources-related assignment.

We provide a full range of services related to the EPA’s NPDES permit including stormwater quantity and quality control, erosion and sediment control plan development, and permit assistance. Because our large client base is spread throughout the Northeast and New England area, our staff is well informed of the specific requirements of each area.

Our extensive experience working with FEMA flood studies on bridge replacement projects, in addition to filing Letters of Map Revision on behalf of our clients, has enabled our team to successfully and proficiently navigate through the FEMA process.

Our staff includes Rosgen-trained environmental scientists competent in applying the principles of fluvial geomorphology, sedimentation, and stream bank erosion to real life situations. Working together with our skilled hydraulic engineers, our diverse team is able to apply problem-solving techniques for watershed management, natural channel design, riparian assessment, and stream restoration to any river morphology project.
