Description

The Las Vegas Valley Water District (LVVWD) is responsible for reliable water delivery to more than 1.5 million people. It manages more than 6,500 miles of underground pipelines within the City of Las Vegas and unincorporated Clark County, including the world-famous Las Vegas Strip. Existing waterlines on Las Vegas Boulevard between I-215 and Sahara Avenue were constructed between 1955 and 1960 and are now in need of replacement. The District’s project, which includes over three miles of 36-inch diameter steel waterline, over 2.5 miles of 24-inch ductile iron pipe (DIP), and several more miles of 16-inch and smaller DIP, is a multi-phase project being constructed in one of the most heavily-trafficked and utilized roadways in Nevada. Simultaneously, Clark County is working to complete an overhaul of the existing roadway, which will include pavement rehabilitation, security improvements, smart data, telecommunications, fiber, storm drain, and sewer improvements, all within the same corridor as the LVVWD project. The presence of so many other utilities within the project alignment, as well as frontage by major businesses which are primary contributors to the Southern Nevada economy, creates unique challenges for designing and constructing a large-diameter waterline. Through an interlocal agreement, the County and LVVWD have combined forces to construct all planned improvements with a single prime contractor. This coordinated approach has been valuable for minimizing impact to resorts, Las Vegas tourism, conventions, professional sports events, airport operations, and other commercial activity near the Strip. Kimley-Horn’s waterline designs for this swiftly changing corridor seek to balance operation and maintenance needs, avoid conflicts with other utilities (existing, planned, and anticipated), and adhere to strict maintenance of traffic requirements. The Kimley-Horn team provided the full suite of design services, including survey, subsurface utility exploration, geotechnical evaluation, waterline design, structural design, plans, specifications, and construction administration.
