Our staff members’ diverse expertise in water quality, construction management, civil engineering, and stormwater monitoring enables us to tackle any issue related to erosion and sediment control on construction sites. We have assisted clients in developing technical guidance for the preparation of erosion and sediment control plans, developing guidance for the selection of erosion and sediment control measures tailored to particular site conditions, and compiling information on the full array of erosion and sediment control products and services that are available to them. Herrera’s experience in monitoring the effectiveness of erosion and sediment control measures at construction sites and monitoring water quality at construction sites provides invaluable insight into the techniques that are most successful under various site conditions. This insight strengthens our ability to anticipate erosion and sediment control problems and to develop effective design solutions for clients. Several of our staff members are certified erosion and sediment control specialists in the state of Washington.
