The U.S. Army Garrison, Fort Greely, Alaska, proposes to establish and operate one or more sources of borrow materials (aggregate and fill materials) on the installation for installation construction projects beginning as early as March 2004. Alternative 1 would establish a new 49-hectare (120-acre) borrow pit northwest of Allen Army Airfield to provide borrow materials for the Allen Army Airfield reconstruction project. Alternative 2 would establish a new 40-hectare (100-acre) Directorate of Public Works Borrow Pit southeast of the main cantonment area on Fort Greely between East Post Road and Landfill Road to be used for current and future public works projects on Fort Greely. Under the No-action Alternative, the U.S. Army Garrison Fort Greely would not establish new sources of borrow materials. Borrow materials for any existing or future projects at Fort Greely would be obtained from an existing borrow pit located adjacent to the Ground-Based Midcourse Defense Validation of Operational Concept test site or purchased from a source outside of the installation., The original document contains color images.

This report presents a decision framework for road management and planning at Eglin AFB, FL. The need for a road plan was denied in the Natural Resource Management Plan. The extent of the problem is enormous because Eglin has an extensive network consisting of approximately 1,500 miles of roads. Two interrelated problems exist: (1) costs of maintaining the roads, and (2) environmental impacts. The report focuses on the second issue. The sandy nature of the installation causes chronic maintenance as well as erosion problems. In addition, road material derived from borrow pits has economic and environmental costs. The unpaved roads and clay pits act as sources of sediment which may be transported into nearby streams. Sedimentation has potential adverse impact to wetlands and stream ecology. To address these problems, a road management workshop was held to offer solutions by reaching a consensus among the various road users. Synthesis of the workshop resulted in the following conclusions: (1) establish a road task force, (2) inventory the road system in terms of mission needs, traffic volume, maintenance conditions, and environmental concerns, (3) enter data into a geographical information system for automated decision making, (4) use weighted criteria to open or close roads, (5) adopt standards for open road construction and maintenance, (6) close roads either temporarily or permanently, and (7) annually review progress. Following these recommendations will result in reducing maintenance costs and minimizing environmental consequences of roads.

THE PURPOSE OF THIS WORK PLAN IS TO OUTLINE THE PROCEDURES AND LOGIC USED TO CONDUCT MATERIAL AND AREA FEASIBILITY SUBTASKS FOR THE FEASIBILITY STUDY (FS) SOILS SUPPORT PROGRAM.

The purpose of this Work Plan is to outline the procedures and logic used to conduct the Material and Area Feasibility Subtasks for the FS Soils Support Program. The purpose of these additional subtasks is to (1) evaluate whether onsite materials are suitable for constructing landfill liners and caps, (2) identify a potential landfill site at RMA, and (3) evaluate the suitability of the proposed site for hazardous waste disposal. The scope of this Work Plan includes a description of the Material and Area Feasibility field subtasks. The Material Feasibility subtask includes borrow area selection, test fill construction, and infiltration testing (sealed double-ring infiltrometer (SDRI) testing and two-stage borehole (TSB) permeability testing). The Area Feasibility subtask consists of 3 deep boreholes (continuously cored for geologic data) and up to 30 boreholes (continuously sampled for geotechnical and geological data). (MM)

There are plans to construct a levee around Renville County Park (a. k.a. Mouse River Park), as part of the Souris River flood control project. A borrow area was selected to provide any additional material needed for levee construction and also serve as a disposal site for unusable material from the cutoff excavation. The proposed borrow area is on private land. The area was surveyed for any cultural resources material. An historic rock concentration located in the borrow area has no potential historical significance nor is it eligible for listing on the National Register of Historic Places. (mm)

Selection of borrow material for use in beach restoration and periodic nourishment requires analysis of the textural differences between the potential borrow and native beach materials. Three quantitative techniques proposed for such analysis are reviewed and compared, and guidelines are suggested for use in planning and designing projects requiring beach nourishment. The techniques are of two types. One is based on the assumption that sorting processes will selectively remove borrow material from the various size classes until a 'stable grain-size distribution' (gsd) is obtained and the placed fill stabilized. The gsd of the native material is used to predict the character of the stable gsd. Methods of this type lead to calculation of a 'fill factor,' an estimate of volume of borrow material required to produce a unit volume of stable beach material. Examination of the conceptual basis for each method suggests that the SPM method may overestimate fill factors whereas Dean's method may underestimate them. A modification in the assumptions underlying the SPM method results in an approach which appears to represent a satisfactory compromise between these alternatives. Another type of technique was proposed by James (1974). It is based on the assumption that no material is absolutely stable, but that erosion rates depend in part on the gsd of the material exposed to existing coastal processes. Prediction of erosion rates associated with a given borrow material is based on observation of erosion rates and textural properties associated with native materials.
