WA FWS LPO MULTI(1) Little Pend Oreille NWR Culvert Improvements

The WA FWS LPO MULTI(1) Little Pend Oreille NWR Culvert Improvements project is a federal initiative to replace six Aquatic Organism Passage (AOP) culverts within the Little Pend Oreille National Wildlife Refuge in Washington. Located approximately 75 miles north of Spokane, the project spans 0.23 miles with an estimated cost between $2,000,000 and $5,000,000. It is structured as a Sealed Bid, Firm-Fixed-Price contract, with a tentative solicitation date in Spring/Summer 2026. The project has multiple completion schedules: Fall 2027 for Schedule A, and Fall 2028 for Schedules B and C. The scope of work includes construction surveys, quality control, erosion control, clearing, excavation, riprap placement, roadway aggregate, and the installation of concrete box culverts and structural plate structures. Mitigation efforts include rock weirs, log barriers, root wads, fish passage boulders, and streambed material/channel realignment. The project also covers temporary and permanent traffic control, and environmental restoration such as seeding and fertilizer application.

This federal government document is a physical data report detailing the clearing limits for a proposed federal project, "WA FWS LPO MULTI(1), Little Pend Oreille National Wildlife Refuge (NWR) Culvert Improvements." Prepared by the U.S. Department of Transportation, Federal Highway Administration, Western Federal Lands Highway Division in Vancouver, Washington, the report was generated on Tuesday, April 7, 2026. The primary purpose of this document is to establish precise geographic coordinates and alignment boundaries for land clearing activities across six distinct construction sites (Sites 1, 2, 3, 4, 7, and 8). The report provides technical survey data generated from a 2D design file (using the active 3D/2D CAD alignment reference "waw-lpo-multi1_clearing.dgn"). For each designated site, the document presents structured tabular data categorized by: * **Baseline Alignments:** Referencing primary control lines MAIN01, MAIN02, MAIN03, MAIN04, MAIN07, and MAIN08. * **Station and Offset Metrics:** Listing specific interval stations and their corresponding positive or negative offsets in feet. * **Geospatial Coordinates:** Providing exact Northing and Easting coordinates for each designated offset point along the alignment. This highly technical data serves as a critical reference for contractors bidding on or executing the culvert improvement project, ensuring that clearing activities remain strictly within authorized environmental and construction boundaries at the Little Pend Oreille NWR.

This physical data report outlines the clearing limits for the proposed Little Pend Oreille National Wildlife Refuge (NWR) Culvert Improvements project [WA FWS LPO MULTI(1)] in Washington. Prepared on April 7, 2026, by the U.S. Department of Transportation Federal Highway Administration's Western Federal Lands Highway Division, the document serves as a technical reference for federal contracting and construction planning.

This geotechnical memorandum, prepared by the Western Federal Lands Highway Division (WFLHD), details the final subsurface investigation results and engineering recommendations for the Little Pend Oreille National Wildlife Refuge Culvert Replacement project in Stevens County, Washington. The project aims to replace six aging and hydraulically undersized culverts along Bear Creek Road and Blacktail Mountain Road with modern, precast concrete box culverts and wing walls to meet Washington State standards for aquatic organism passage (AOP). To evaluate subsurface and groundwater conditions, WFLHD advanced 12 test pits (one upstream and one downstream at each site) in October 2021. Soil index and laboratory testing classified the native materials primarily as nonplastic granular soils, ranging from silty sands to poorly graded sands with gravel. Depth to groundwater was typically observed near the bottom of the test pits, fluctuating in close proximity to the stream levels. The native soils at all sites are deemed sufficient for founding the proposed AOP structures. The memorandum provides recommended foundation design parameters, including a nominal bearing resistance of 4,500 psf and lateral earth pressure coefficients for the wing walls. From a construction standpoint, the presence of boulders up to 4 feet in diameter is expected across multiple sites, and shallow bedrock was encountered at Culvert Site 8, requiring specialized excavation methods. Lastly, the report assesses the suitability of onsite excavated materials for reuse as backfill or structural backfill under standard highway specifications.

This geotechnical memorandum presents the results and recommendations of a supplemental subsurface investigation conducted on June 15, 2022, at Culvert Site 8 within the Little Pend Oreille National Wildlife Refuge in Stevens County, Washington. Prepared by the Western Federal Lands Highway Division, the report details the findings from four additional test pits advanced to confirm bedrock elevations. This investigation aims to limit excess rock excavation for a proposed precast concrete arch culvert with spread footings along Blacktail Mountain Road. Subsurface conditions at Site 8 consist of variable thicknesses of topsoil, road fill, and glacial till containing cobbles and large boulders up to 5 feet in diameter, overlying schist and competent granodiorite bedrock. Groundwater was encountered at depths between 4 and 8 feet. Based on these findings, the memorandum provides specific engineering recommendations that supersede previous guidance. Key design parameters include a recommended nominal bearing capacity of 8,000 psf on competent granodiorite and lateral earth pressure values for foundation and wing wall design. For construction, contractors must prepare for challenging excavation through glacial drift containing nested boulders and expect to encounter shallow groundwater requiring dewatering and shoring. Crucially, the report notes that rock excavation will be required to fund the culvert, and blasting techniques may be necessary, superseding previous "no blasting" restrictions.

This document is the Stormwater Pollution Prevention Plan (SWPPP) narrative for the Little Pend Oreille National Wildlife Refuge (NWR) Culvert Improvements project in Stevens County, Washington. Prepared by the Federal Highway Administration’s Western Federal Lands Highway Division, the project involves replacing six aging, hydraulically undersized culverts along Bear Creek and a tributary to the North Fork Bear Creek. The goal is to meet Washington State fish passage standards, restore aquatic habitat connectivity for resident native trout, and modernize local road infrastructure. The project's estimated construction timeframe runs from July 1, 2026, through October 29, 2027, with a total disturbed area of 1.6 acres. To comply with the U.S. Environmental Protection Agency’s (EPA) Modified 2022 Construction General Permit (CGP), the SWPPP details erosion, sediment, and pollution controls, alongside a construction sequencing schedule spanning multiple phases. Because the project involves extensive, direct in-water work, maintaining a standard 50-foot undisturbed natural buffer is infeasible. Consequently, the contractor will implement equivalent sediment reduction practices and in-water isolation protocols to minimize turbidity. In compliance with other federal mandates, the project has successfully concluded Endangered Species Act (ESA) Section 7 coordination with the U.S. Fish and Wildlife Service (USFWS), receiving a "Not Likely to Adversely Affect" determination for the Yellow-billed Cuckoo, and has documented Section 106 National Historic Preservation Act compliance showing no adverse effects on historic properties.

This federal government document contains engineering cross-section drawings for the Little Pend Oreille National Wildlife Refuge (NWR) Culvert Improvements project in Washington State (Project Number: WA FWS LPO MULTI(1)).

This document details the Federal Highway Administration’s (FHWA) compliance with FAR 36.211, which mandates the disclosure of procedures and historical data regarding the definitization of equitable adjustments for construction contract change orders. Currently, the FHWA has no agency-specific additional policies or procedures beyond standard Federal Acquisition Regulations. The document provides a performance data table tracking the time required to definitize change order proposals after receiving an adequate proposal across fiscal years (FY) 2021, 2022, and 2023. Over this three-year period, the agency definitized a total of 21 change order proposals. The majority of these proposals were settled within 91 to 180 days (10 total), followed by six settled within 31 to 90 days, two within 30 days, three within 181 to 365 days, and two taking 366 days or more.
