BACKGROUND
The Sailing Lake Access Road Improvement project is part of the City’s Sea Level Rise Capital Improvement Program, which includes various projects in the North Bayshore Area to increase coastal and fluvial flood resiliency and to improve and restore tidal marsh habitats along the shoreline. The Sailing Lake Access Road is located between the Sailing Lake and Coast -Casey Forebay in Shoreline at Mountain View (Figure 1).
The plans and specifications for Sailing Lake Access Road Improvement, Construction, Project 21-53, were approved by the City Council on June 22, 2021, and the project construction was mostly completed in winter 2021. The project strengthened the embankment of the Shoreline Lake d am and address ed seepage issues at the downstream toe of the dam to meet the California Department of Water Resources, Division of Safety of Dam (DSOD) safety standards. In addition, the roadway over the dam was improved to support the anticipated heavy truckloads during construction for the South Bay Salt Pond projects, the future Coast-Casey levee improvement, and other future projects in the area as well as provid e access for ongoing City operations and maintenance and public trail access. As a part of the project construction, some of the existing underground water and gas utility lines were replaced for dam safety compliance and improved maintenance access. The City is currently preparing postconstruction reports to regulatory permitting agencies and DSOD.

ANALYSIS
There were multiple rain events in December 2021 , and unforeseen site conditions , such as additional ground seepage, which delayed the project and extended the construction period to April 2022. Due to the construction delays, the project required additional time and efforts from AECOM for construction support and environmental monitoring to minimize the risk of potential habitat impacts from the project construction and to avoid interruption s with DSOD coordination. As a result of this additional effort, the basic services and additional services budget in the agreement have been fully expended. T o complete the remaining tasks to close out the project, an amendment is required to augment the budget of the AECOM agreement.
The rema ining tasks for AECOM include preparing postconstruction reports and performing postproject environmental monitoring, such as vegetation establishment . A n additional $102,553 is required for this project support, bringing the total agreement not-to-exceed amount to $402,553.
FISCAL IMPACT
Sailing Lake Access Road Improvement, Construction, Project 21 -53, is funded with $2,400,000 from the Shoreline Regional Park Community Fund. There is sufficient funding in Project 21-53 to add $102,553 to the AECOM professional services agreement.
ALTERNATIVES
1. Do not authorize adding compensation to the AECOM agreement , and direct staff to find alternate support to close -out the project and perform postproject environmental monitoring.
2. Provide other direction.
