BACKGROUND/DISCUSSION:
On May 13, 2024, the City of Pacifica approved a Master Consultant Services Agreement and Task Order No. 1 with Cotton Shires and Associates (CSA) to initiate preliminary studies, including topographic surveying and geotechnical and slope stability analyses, for multiple landslide sites within the City. Following recent FEMA and Cal OES obligation of four of these landslide repair projects, staff recommends approval of a budget amendment to the CSA contract in the amount of $71,680.00 to complete the Plans, Specifications, and Estimates (PS&E) necessary to prepare the projects for construction. With this amendment, the total CSA contract amount would increase to $291,460.00.
The proposal from CSA includes preparation of Plans, Specifications, and Estimates (PS&E) for the landslide repair projects located at 1475 Rosita Road and along Sharp Park Road. In addition, CSA will revise the existing designs and complete the PS&E for the Adobe Drive and Higgins Way retaining wall project and the 601 Talbot Avenue sewer pipeline replacement project. During the winter storms in 2023, at 1475 Rosita Ave, a landslide of approximately 50 feet in length and 5 feet in height slid into the Adobe Creek and left the resident’s backyard unstable and CSA’s design calls to replace with a keyway and fill and compact to match what was existing prior to the storm damages. At 601 Talbot, a landslide of approximately 100 feet Pacifica City Council 2

wide, 25 feet high, and 25 feet deep crushed the sewerline that serves several houses on Talbot Ave and CSA’s design calls to trench through the compacted debris and replace the whole line.
On the corner of Adobe & Higgins, the retaining wall in the City’s right of way was damaged by the major storms and caused about 65 feet wide of the wall to collapse and CSA is designing to replace the entire 100 foot wide retaining wall. At Sharp Park Road, the hillside gradually eroded over several years and CSA is working with a structural engineer to design a new retaining wall/v-ditch at the top of the hillside.
The City Manager recommends approval of Amendment No. 1 with Cotton, Shires and Associates, Inc.
ALTERNATIVE ACTION:
The Council may choose not to approve the amendment and agreement. Staff does not recommend this alternative action.
RELATION TO CITY COUNCIL GOALS AND WORK PLAN:
· Improve and steward City infrastructure, streets and facilities: The repair of the storm damage will improve the areas and prevent further damage.
FISCAL IMPACT:
The original contract of $219,780.00 was from the Disaster Accounting Fund 38. The Talbot Avenue and Rosita Road has been approved by Federal Emergency Management Agency (FEMA), and Adobe Drive is in the last approval stage. Staff is requesting reimbursement from the Federal Emergency Management Agency (FEMA) for the geotechnical services.
The funds for Sharp Park Road was approved from Disaster Accounting Fund 38 as part of the FY 25-26 budget for the Sharp Park Road Slope Erosion Repair Project.
