BERTHOUD ALLEY IMPROVEMENTS 1-2-Iowa-Colorado.pdf

These civil construction documents detail the Berthoud Alley Improvements project located in Section 24, Township 4 North, Range 69 West in the City of Berthoud, Larimer County, Colorado. The project involves infrastructure improvements across multiple avenues including Michigan Avenue, Colorado Avenue, Iowa Avenue, and Nebraska Avenue. The project scope includes 36 cubic yards of unclassified excavation, 967 square yards of subgrade preparation, 829 square yards of 4-inch hot mix asphalt, 65 square yards of 8-inch concrete drive apron, and 622 linear feet of concrete pan with fibermesh reinforcement.

The project is part of the 2025 Berthoud Road Improvements initiative, which encompasses asphalt mill and overlay, alley reconstruction, and curb-gutter-sidewalk work. The contract documents specify that all work must be completed before August 31, 2025, and require adherence to CDOT standard specifications for ADA ramps, sidewalks, and curbs, with some areas potentially matching existing conditions. The project drawings include detailed plan and profile views, showing precise grading, alignment, and infrastructure placement specifications for the alley improvements.
