About this file

Written by GovTribe AI · Jul 25, 2025

These are engineering and design drawings for the Glasgow Stream Crossing Improvements project by the Bureau of Land Management (BLM) in Valley County, Montana. The comprehensive set of 19 detailed sheets includes site surveys, culvert installation plans, and technical specifications for improvements at three locations: Cactus Flats Road, Triple Crossing Road, and Gutshot Dam.

The project involves multiple critical infrastructure enhancements, including: installing a 24-foot box culvert on Cactus Flats Road, replacing three culverts on Triple Crossing Road to improve drainage and road stability, decommissioning outlet works at Gutshot Dam, and constructing a low-water crossing. Technical details cover excavation, culvert installation, riprap armoring, erosion control, and roadway reconstruction, with specific requirements for material types, installation methods, and environmental considerations. The drawings provide precise engineering specifications, site layouts, cross-sections, and installation details for each project component, indicating a comprehensive approach to stream crossing and road infrastructure improvements.

CONSTRUCTION NOTES

[1] More than the minimum of one fastener per square yard may be required due to conditions such as blanket composition, soil type, surface uniformity, and slope steepness.

[2] See Standard Specification 629.

Use manufacturer's requirements. When manufacturer's requirements are not provided, use installation requirements shown on Standard Plans.

[3] Additional staples may be required on slopes greater than 3H : 1V.

INSTALLATION STEPS

[1] Prepare smooth slope.

[2] Dig anchor trench. Set aside native soil removed from trench.

[3] Secure blanket in anchor trench, staking or stapling blanket as shown.

[4] Replace native soil previously removed from trench.

[5] Roll blanket down the slope in a controlled manner, taking care to remove excess slack, and taking care not to stretch blanket.

[6] Stake or staple blanket as shown so there are no gaps between the blanket and the soil.

Staple while unrolling blanket to minimize walking on blanket.
