The Quartz Hill Drain And 50th Street West consists of construction of a new underground storm drain system along 50th Street W between Avenue K and Avenue M-8, and road improvement through Quartz Hill downtown. Currently, Quartz Hill community does not have an underground storm drain system which results in severe flooding and significant disruptions when it rains. The new drainage system and road improvement is designed to keep the streets of Quartz Hill dry during future storm events. The project is within the unincorporated community of Quartz Hill and City of Lancaster and will be built at no added tax or assesments to the property owners.

The portion of this project consists of the construction of underground storm drain in the unincorporated County area of Quartz Hill. Starting at Avenue M-4 near Palmdale, the storm drain line runs north under 50th Street West and will connect to the City of Lancaster's existing 96-inch underground storm drain line at Avenue K. Lateral lines on either side of the new underground storm drain line will drain water off the adjacent streets that are subject to flooding.
