Bay St. & Ford Road Alley Reconstruction Project


OE provided design, topographic survey and geotechnical investigation services for this CDBG-funded alley reconstruction project. The project spanned roughly 1,000 LF along Bay Street Alley and Ford Road Alley. Plans included plan and profile, cross sections and special details. A cost analysis was conducted to provide the City of Costa Mesa with cost-to-lifespan design alternatives, including, Asphalt Rubber Aggregate Membrane (ARAM), Asphalt Rubber Hot Mix (ARHM), Cold-In-Place Recycling (CIR), Full Depth Reclamation & Sub-grade treatments. Full-depth PCC reconstruction with rebar reinforcement was determined to be the most cost effective solution. Due to the extreme degradation of the alley, our team was required to assess grades and drainage patterns of the alley to ensure all drainage would be adequately directed through the project site. This included analysis and design of the adjoining AC pavement on private property to ensure proper drainage from adjacent properties to the alley. The design team also coordinated with SCE to have conflicting utilities relocated prior to the project going to bid.
