Recommendation:
It is recommended that the City Council of the City of Calexico approve the following:
1. Authorize Public Works Director/City Engineer to Sign Change Order No. 2 with Rove Engineering, Inc. in the amount of $191,308.50 for Scaroni Road Pavement Rehabilitation State Project No. LPPSB1L-5168(034).
Background:
The City of Calexico Public Works Department received a grant from California Department of Transportation (Caltrans) for FY 2023-2024 in the amount of $942.000.00 ($471,000.00 - State Grant and $471,000.00 - Local Match) for the Project No. LPPSB1L-5168(034) - Scaroni Road between Cole Boulevard and Jasper Road. The construction work consists of survey monument preservation, milling existing asphalt concrete pavement to a depth of 2', installation of a stress absorbing membrane interlayer (SAMI) with 3/8" aggregate over the milled surface, placement of 2" asphaltic concrete overlay surfacing over the SAMI, traffic striping and markings, sewer manhole rehabilitation, and traffic control.
On November 6, 2024, the City Council of the City of Calexico approved bid documentation for Scaroni Road Pavement Rehabilitation State Project No. LPPSB1L-5168(034) and authorized the Public Works Department to send the project out to bid.
Docusign Envelope ID: CF0BB8CF-E216-4E91-95D8-8993678A5EEF On May 7, 2025, the City Council of the City of Calexico approved the following:

Base Bid) as Per City Ordinance No. 1218. d) Adopt Budget Amendment Resolution for Fund No. 412 - State Grant.
On September 3, 2025, the City Council authorized the City Manager to sign Change Order No. 1 with Rove Engineering, Inc. in the amount of $88,776.00 for the removal and replacement of four (4) 48" diameter sewer manholes on Scaroni Road.
Discussion and Analysis:
On July 23, 2025, Rove Engineering, Inc. began working on Scaroni Road Pavement Rehabilitation Project. The original specifications included road rehabilitation comprised of a 2- in mill of the existing A.C. paving, installation of a Stress Absorbing Membrane Interlayer (SAMI) and the installation of 2-in Hot Mix Asphalt. This proposed solution to extend the useful life of an asphalt pavement, although cost effective, requires that the structural integrity of the pavement is in adequate conditions, such as: a well compacted subgrade, a base layer that has a thickness appropriate to the vehicle loads that will be traveling on the road and compacted to a 95% relative density, and an Asphalt Concrete layer without major structural deficiencies.
At the beginning of the project, Rove Engineering conducted a pavement coring plan, to gather information on the existing paving structure along Scaroni Road, and to confirm that the proposed rehabilitation solution would be appropriate for the existing conditions of the road. The results of the coring indicated that sections of the road DO NOT HAVE BASE MATERIAL UNDERNEATH, creating weakness in the overall capacity of the pavement to bear the loads it is intended to withstand. Consequentially, the existing potholes are of such depth, that additional void areas will keep forming in the structure, compromising the integrity of the road and the safety of its users.
After discussions between the City of Calexico (Owner), Rove Engineering (Contractor), Dynamic Consulting Engineers (Resident Engineer) and Kimley Horn (Engineer of Record), Rove Engineering recommended the removal of 8-in of the existing asphalt, pulverization and treatment for its use as base, followed by the installation of a 4-in layer of ¾-in HMA Pavement Mix. This change in scope will undoubtedly yield a product without any underlying deficiencies, to the benefit of the City of Calexico.
For this reason, City staff is recommending that the City Council of the City of Calexico authorizes the Public Works Director/City Engineer to sign Change Order No. 2 for Scaroni Road Pavement Rehabilitation Project.
