Body
BACKGROUND & HISTORY:
The Dominguez Ranch Slope Improvements Project, No. FC-2023-03 (Project) area is located in the slope areas behind 1559 and 1563 Dominguez Ranch Road residences in the City of Corona’s Landscape Maintenance District 55 (LMD 55) of the Sierra Del Oro community in the City of Corona. The subject slope area is a steep natural slope approximately 200 feet long that descends approximately 80 to 90 feet to the adjacent Fresno Canyon Trail below. The top of the slope has been subject to erosion within close proximity to the existing perimeter wall/fences and backyard improvements of the subject residences.
The project shall repair the eroded areas, mitigating potential future slope failure and erosion. The project includes the placement of soil cement sourced from local soil to restore the eroded slope area. Also, new vegetation will be placed along the soil-cement to further fortify the slope. Finally, a new V-ditch and irrigation line will be installed to service the project site.
ANALYSIS:
The Plans and Specifications for the Project were completed by Hunsaker & Associates and reviewed by City staff. On October 7, 2020, the City Council awarded the professional engineering services for the project to Hunsaker & Associates.
The Project was advertised for bids on June 22, 2023, pursuant to Corona Municipal Code 3.08.090 Public Projects - formal bidding procedure and Public Contract Code requirements. On July 20, 2023, six (6) bids were received through the PlanetBids bidding service.
The following is a summary of the bid results and the Engineer’s Estimate:
