BACKGROUND
Excessive rains saturated a 160-foot-long portion of Oakville Grade Road near MPM 1.35 causing movement of the road and supporting ground in early 2019. The damage occurred during a declared disaster event and FEMA inspected the site on August 15, 2019. Through a qualifications-based process, the County selected MGE Engineering Inc. (MGE) as the most qualified firm for this investigation and design of the project. On August 18, 2020, the Board of Supervisors (Board) awarded a Professional Services Agreement to MGE for a maximum of $298,735 for the surveying, geotechnical and design services through project completion. The Board also approved a budget transfer of $69,331 to fund the preliminary design and engineering phase. On March 16, 2021, the Board approved a budget transfer of an additional $44,998 to complete the preliminary design and engineering phase.
On January 24, 2023 the Board approved a budget transfer of $268,280 to fund MGE's Phase 2 Engineering Design services as well as additional staff time through the design and bidding phase of the project after FEMA approved the proposed project scope, method of repair and cost to restore the facility back to pre-disaster conditions which consists of a 160-foot-long soldier pile wall as well as asphalt and road base replacement, soil stabilization, culvert replacement, and guardrail installation at the shoulder.
