Valmonte Drive / Stewart Road Storm Drain Improvement Project

Valmonte Drive / Stewart Road Storm Drain Improvement Project

The project consists of upgrading an existing storm drainage system. The upgrade will provide improved storm water conveyance and alleviate flooding along Valmonte Drive between Surita Street (west) and Azure Ct., at the intersections of Surita Street at Valmonte Drive and Surita Street at Stewart Road, and in the vicinity of Lazo Ct. and Vico Way. Piped storm water flow will drain westerly along Arden Way and Valmonte Drive, northwesterly along Stewart Road, and northerly along Surita Street and Azure Ct. The project has three pipeline components, all within the public right-of-way. The first component replaces 4 manholes and 4 inlets; and upsizes 783 linear feet of existing pipe along Lazo Ct., along Stewart Road between Lazo Ct. and Valmonte Drive, and along a short segment of Valmonte Drive. The second component replaces 4 manholes and 5 inlets, and upsizes 548 linear feet of existing pipe along Vico Way and Surita Street. The third component replaces 4 manholes and 4 inlets; adds 5 new manholes; and replaces or adds new 2,041 linear feet of pipe along Azure Ct., Surita Street and Arden Way. In addition to the three pipeline components, 2 inlets will be replaced on Surita Street near Valmonte Drive (west), 4 on Surita Street near Stewart Road, and 4 on Valmonte. In total, 3,914 linear feet of pipe (542 linear feet is lateral [inlet-to-manhole] pipe), 17 manholes, and 23 inlets will be installed. Improvements to the pipe and inlet system will better convey runoff during minor and major storm events and will reduce the chronic localized yard, street, and structure flooding that residents currently experience. The use of increased pipe sizes, new pipe, and additional drainage inlets will effectively convey flow as well as serve as in-line detention storage. This attenuation is designed to prevent flooding downstream.
