Middleton Wash Trail Construction Project

This is a set of construction plans and specifications for the Middleton Wash Trail project prepared by Alliance Consulting for the City of St. George, located in Washington County, Utah. The project involves the design and construction of a multi-use pedestrian trail system spanning approximately 25.75 stations (roughly 2.5 miles) through Middleton Wash, with two main trail segments: the North Trail and the South Trail. The scope of work includes traffic control, site demolition and removals, grading and earthwork, storm drain installation (12-inch to 24-inch PVC and HDPE pipe systems with multiple inlet structures), asphalt paving (2.5 inches on 6-inch gravel base), concrete flatwork and sidewalks (4-inch concrete on 4-inch base), trail safety railings (approximately 2,270 linear feet), multiple retaining walls and rock walls (varying heights from 0.5 to 10 feet with approximately 15,000+ square feet of wall surface), directional and warning signage, an 80-foot pedestrian span bridge with concrete abutments, and miscellaneous site improvements. The project includes stormwater pollution prevention plans (SWPPP) with silt fencing (approximately 4,625 linear feet), tracking pads, berm bags, and rip-rap stabilization at storm drain outlets.

The plans establish comprehensive construction notes and specifications requiring compliance with City of St. George ordinances, Utah State Administrative Codes, International Building Code, and International Plumbing Code standards. The contractor bears responsibility for utility coordination and location verification, obtaining UPDES/NOI permits and encroachment permits, staging coordination with the city, dust and sediment control, compaction testing, geotechnical report compliance, and protection of existing facilities including overhead power lines and underground utilities. Performance and labor/materials bonds of 100% are required, along with a 5% bid bond. The project requires extensive coordination with multiple utility providers including St. George Energy Services for power work, Dominion Energy for gas lines, and various telecommunications providers (GO Fiber, CenturyLink, TDS). Control points and benchmarks are established for survey purposes, with existing contour intervals at 2-foot increments and finish grading tolerances of 0.1 feet. Shop drawings are required for all retaining wall systems.
