The project is limited to one encroachment. The project goal is to maintain approximately 3,500 feet of drainage channel between July 1 and September 1, 2020. Approximately 2,000 feet of the channel is perennial, while 1,500 feet is ephemeral. Channel flow capacity reduction is the result of increased aquatic vegetation density and decreased sediment routing. Reduce channel capacity has increased adjacent pasture flooding depth and rate. Maintenance activities includes removal of vegetative material and sediment deposits from the drainage ditch channel and channel reshaping. Where water is present on site, a coffer dam will be installed utilizing hay bales and plastic with water being pumped downstream of the site. Excavation and channel maintenance will not be allowed in flowing water. Due to the length of the project area, installation of more than one coffer dam will be required. Upon completion of work in any channel reach (not to exceed 1,000') such coffer dams shall be removed and any flow present reestablished. During this maintenance activity the excavated material will be placed on stable areas adjacent to the channel and shaped, or placed in stock piles and allowed to dry sufficiently to be handled. Stockpiles will be trucked to an appropriate disposal site off property. Any bare mineral soil developed during the excavation, outside the ditch channel, will be seeded to grass at the rate of 30lbs. per acre.
