In 1986, an Engineer's Report, prepared by County Flood Control District staff, suggested twelve possible alignments including retention basins, subsurface storm drains and open channels. However, the proposed alignments were found to environmentally impact the habitat of the Delhi Sands Flower Loving Fly along the extension of Pepper Avenue, south of Slover Avenue. In 1995, the County of San Bernardino and the City of Colton agreed upon a Memorandum of Understanding (MOU) establishing terms and conditions for the design and construction of various transportation, flood control and infrastructure improvements relative to the construction of the Arrowhead Medical Center.

On June 6, 2006, the City Council authorized the a award of the construction contract for the Comprehensive Storm Drain 3-5 Project- Phase III to Harris Construction Engineering, Inc. The awarded contract totaled $2,019,411. Phase III of the Comprehensive Storm Drain 3-5 Project will install 2,016 lineal feet of 108" reinforced concrete pipe along Valley Boulevard from Meridian Avenue to Cypress Avenue.

ANALYSIS/DISCUSSION: A one hundred (100) feet section of Phase III runs under a Union Pacific Railroad Bridge (east of Hermosa Avenue). It will be necessary to use a jack and bore method of pipe installation rather the
