The documentation <br /> consisted of a photographic record of the construction, including excavation, installation of the <br /> flow control piping, rock-bed, amended soils, and pond formation. The contractor also measured <br /> the bottom areas for Mr.Ash, noting that the average floor area for all cells is likely to exceed 400 <br /> square feet minimum bottom area for rock the beds. <br /> The amended soil blend was the Ferti-mulch product prepared by the Thomas Family Farm, <br /> (Topsoil's Northwest Inc.) on Marsh Rd in Snohomish, Washington, which is made of a high <br /> quality compost produced from manures and bedding materials and is cured for at least one year. <br /> Land Technologies has experience with this product and facility and consider it one of the better <br /> products for use in bio-cell construction. It is a consistent product the meets the DOE permeability <br /> and organic content requirements. <br /> A photo of the completed cell with landscaping and hydro-seed is provided for the record. <br /> Although the photo is of poor quality, it appears to show the correct formation and level bottom <br /> area along with perimeter landscaping and hydro-seed. <br /> 18820 3rd Ave NE - Arlington.
