The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. The Project Corridor is located on highway 110 at milepost 11.6 as shown on the Vicinity Map, Figure 1. The project lies within Township 6 N, Range 5 W, Section 13 near Mist, Columbia County. As shown on the Site Map, Figure 2, this is primarily a rural and forested area and adjacent properties are rural residential single-family residences and a grade school. Beyond is mostly forested land with some limited agricultural use. The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. The work to which the Specifications, provisions, and Special Provisions contained herein apply, the time and place at which Bids for the Work are to be received, and other information pertinent to the Specifications and provisions, including any statements required to accompany the Bid, and their application are described and stated on the sheet or sheets inserted between printed pages [2] and [3] hereof. This Work consists of constructing waterway enhancements such as fish Rocks, large woody Material (LWM), engineered streambed Material, and other types of waterway items as shown or directed. a) The recommendation is to install a new culvert at this creek crossing. The proposed culvert shall be an 8-foot diameter round pipe with sloped ends. The new pipe will be countersunk 2 feet below the creek channel bottom. b) Implement temporary water management components to perform the work under dry conditions c) Remove the existing pipes d) Re-construct the impacted and damaged roadway section e) Culvert Inlet - Utilize Class 200 riprap to armor embankment f) Utilize jetty rock and riprap to armor the eroded river bank to prevent additional bank erosion. Utilize jetty rock to establish the revetment toe. Utilize Class 2000 riprap to armor the bank slope and around the culvert outlet. The jetty rock should be placed along the base of the slope utilizing an excavator bucket. The Class 2000 riprap should be placed utilizing an excavator bucket. Compact the rock material throughout installation by tamping it with the excavator bucket. Assumptions: o The highway is closed to traffic and it is assumed that repair work will be performed under total road closure conditions o No streambed material will be placed within the barrel A list of materials, estimated quantities, and approximate costs is noted in Figure 1. The OR202 replacement costs does not include mobilization. Notes: Excavation below OHW: +- 85 cu. yards, Riprap installed below OHW: +- 120 cu. yards a) The recommendation is to install 3 pipes (culverts) placed side by side at this creek crossing. The proposed culverts shall be 6 foot diameter round pipes with sloped ends. The new pipes shall be placed at the same alignment as the failed culvert. The center 6 foot diameter pipe invert shall be installed 6-inches below the channel thalweg as directed by the engineer. b) Culvert Inlet - Implement a temporary install of Class 700 riprap to armor the embankment and around the culverts (Standard Drawing RD317). Permanent install is concrete sloped pave ends and cutoff wall to be coordinated during the in-water work period. Install Class 700 riprap to armor embankment (Standard Drawing RD317) c) Culvert Outlet - Install Class 700 riprap to armor the embankment (Standard Drawing RD317). Install a cutoff wall made from riprap (Standard Drawing RD317) d) Implement temporary water management components to perform work in dry conditions. The use of pump(s) will require a trained contractor employee to monitor and operate the pump 24 hours a day. e) Remove the existing pipes f) Re-construct the impacted and damaged roadway section. Implement a temporary driving surface utilizing compacted aggregate base in the interest of getting the highway open as soon as possible.
