About this file
This is a construction design document prepared by the City of Orem, Utah, Community Development Engineering Division for the 2000 S Storm Drain Project (Project Number 25-044). The project encompasses the installation of approximately 1,415 lineal feet of 48-inch Class III Reinforced Concrete Pipe (RCP) storm drain infrastructure extending from Geneva Road to approximately 600 West in Orem. The system includes five new storm drain structures (SD #01 through SD #05) with 72-inch diameter precast concrete manholes, connecting to existing Provo storm drain infrastructure at the eastern terminus. The design incorporates varying pipe grades ranging from 0.50 percent to 10.57 percent slope, two standard pre-treatment structures for development runoff, and provisions for future 48-inch pipe connections. The construction drawings are presented at multiple scales with detailed plan and profile views showing invert elevations, rim elevations, pipe sizes, and connections to existing systems, including existing Provo water and gas crossings.
The design specifications require all precast manhole sections to meet AASHTO HS-20 loading standards and incorporate solid manhole covers and frames meeting A-1180 specifications. Pipe bedding shall consist of sand with a minimum 12-inch depth above the pipe, compacted to 90 percent Standard Proctor maximum density. Concrete collars of minimum 4,000 PSI strength with 1.5 pounds per cubic yard of fibers are required for grade adjustments at structure locations. The project includes provisions for protecting and adjusting existing survey monuments to finished grade and installing future-use manhole sections with solid walls for 48-inch pipe connections by others. Design documentation indicates completion as of May 2026, with drawings prepared in March 2026.
