EXECUTIVE SUMMARY
On March 25, 2026, City Council awarded an agreement to Apena Engineering, Inc., in the amount of $611,622, which included a 10% contingency for the modification and rehabilitation of four (4) existing storm drains to prevent flooding on Shoreline Drive. The improvements made under the subject agreement are complete and acceptable to staff. Staff recommends City Council accept the work and the as-built plans, included as Exhibit 1.
BACKGROUND
Stormwater systems are a vital component of the City of Alameda’s (City) infrastructure, collecting and conveying stormwater away from streets and other public areas to reduce flooding and maintain safe, accessible transportation routes. The areas around the intersections of Shoreline Drive and Willow Street, and of Shell Gate Place, have historically flooded when the storm system cannot discharge stormwater to the Alameda beach area. The Retrofit of Shell Gate Place & Willow Street Outfalls Project rehabilitated and fortified four (4) existing storm drains and installed four (4) new outfall and overflow structures to improve drainage and reduce localized flooding. These improvements will also improve the safety and reliability of roadways, walkways, and bikeways in the area.
DISCUSSION
On March 25, 2026 City Council awarded an agreement in the amount of $611,622, including contingency, to Apena Engineering for the Retrofit of Shell Gate Place & Willow Street Outfalls Project.
The project is complete and acceptable to the City Engineer. Staff recommends that City Council accept the work and the as-built plans, included as Exhibit 1.

CLIMATE IMPACT
A functioning stormwater system is an important component of the City’s ability to adapt to changing climate conditions and build resilience to flooding. This project improves the near-term reliability and capacity of existing stormwater infrastructure at locations that have experienced localized flooding. Maintaining and improving existing drainage infrastructure supports the City’s broader efforts to increase the resilience of critical public assets, consistent with Strategy I1 of the City’s Climate Action and Resiliency Plan (CARP).
The Contractor was also required to recycle 95% of concrete and 65% of all other construction and demolition debris in accordance with Section 10-5 of the Special Provisions, consistent with the City’s waste reduction and recycling goals.
