Y -- HOLDER AND KIRKENDOLL REVETMENT PROJECTS SOL DACW57-96-B-0034 DUE 091996 POC Contract Specialist MARTINA HARWOOD (503) 326-5816 (Site Code DACW57) Holder and Kirkendoll are federal riprap revetment projects that were damaged by the spring floods. Kirkendoll and Holder locations are situated on Cowlitz River, approximately 3 miles upstream of Toledo, Lewis County, Washington. Contractor work is required to restore the projects to pre-flood condition, which includes excavation and the placement of embankment (11,000 cubic yards at Kirkendoll), gravel (Kirkendoll-6,000 CY, Holder-2,800 CY), gravel bedding (630 tons-Holder), riprap (Kirkendoll-10,200 tons, Holder-2,600 tons; 200-800 pounds to the piece), soil (Kirkendoll-1,700 CY, Holder-200 CY), and seeding (Kirkendoll- 5,100 Square Yards, Holder-600 SY) fertilizing and mulching soil blanket and areas disturbed by construction. Holder location will require the bankline to be filled out to match the alignment of the intact revetment, a 12 inch thick layer of gravel needs to be placed between the embankment and the Class III riprap (if embankment is sand or fine soil) which is to be placed directly on the slope. Kirkendoll has a temporary berm constructed over 1200 feet of the revetment (downstream). The riverward portion will require layering of Class III riprap. Below water surface and near water surface and near water surface excavation of gravel is required to establish the toe of the riprap below the elevation of the river channel bottom. The landward slope of the berm will be reinforced by placing gravel and cobble embankment material taken from the site. The reinforced slope will be covered by a one foot thick layer of soil blanket and seeded to grass. There are several areas upstream of the revetment that were destroyed that require placement of riprap directly on the slope. The in water work period will require this work to be completed as soon as possible. Technical questions may be addressed to Dick Gamble at 503/326- 5510.
