About this file

This is a construction set drawing for the AFD Visitor Center Remodel project located at 5765 W Broadway Street in Missoula, Montana. The document is sheet C101, the Overall Site Plan, prepared by Mosaic Architecture dated September 30, 2024.

The project involves site work and utility improvements for the existing visitor center building. Key infrastructure elements include 84.4 linear feet of 6-inch SDR 35 PVC storm drain with a 2.70% slope, 19.5 linear feet of 10-inch SDR 35 PVC with a 1.30% slope, and 53.8 linear feet of 6-inch SDR 35 PVC with a 1.17% slope. Two 30-inch storm drain inlets are specified with detailed invert elevations and grate elevations. The plan shows connections to existing storm drain infrastructure with specific grout sealing requirements for new pipe penetrations. Construction notes require placement of new weed mat with shredded cedar mulch in disturbed landscaping areas, installation of 20 shrubs minimum 2 feet in diameter distributed across the site, and two evergreen trees with minimum 4-inch caliper on the west side of the building. Additional work includes new concrete sidewalks (4-inch), concrete stoop with 1.50% slope away from doors, and grading depressions to direct water to new inlets. Option items include standard curb and gutter installation, additional sidewalk work, and asphalt patching to match existing conditions. The plan indicates existing utilities including water mains, sewer lines, gas lines, and telephone lines requiring coordination during construction, with specific cautions marked for solar cable and buried gas and telephone crossings.
