Thank you, Mr.

Clerk.

Please call item one.

Yes, item number one.

Here's a resolution approving and authorizing the general manager of the Public Utilities Commission to execute a memorandum of agreement with the City of Daily City for the funding construction and operation of the Vista Grande drainage basin improvement project with a duration of five years, starting August 1st, 2025 through August 31st, 2030, pursuant to the charter.

Madam Chair.

Thank you.

So for this item, Mr.

Obe Nzewi, Groundwater Program Manager of the Water Enterprise of the SFPUZ PUC.

I understand will be presenting on this item today.

Mr.

Nzeli, please go ahead.

I'm the groundwater program manager for the PUC in San Francisco and the project manager on our side for this work.

I will be presenting on this item, giving you a brief background of the project, what the project entails, and then what we're asking for at the end of this.

And I'll be available to answer any questions if there are any regarding the project.

So the Vista Grande drainage basin drains stormwater from the northern portion of Daly City.

That stormwater flows into the Vista Grande Canal and Tunnel System.

That system runs from Daly City through San Francisco along John Muir Drive.

It ties into the Vista Grande tunnel that exits at Fort Funstone and transfers their stormwater to the ocean.

The main issue we're dealing with here is that the canal and tunnel system together do not have enough capacity to handle peak flows during large storm events.

So that results in flooding in Daily City in residential areas in Daily City and also in San Francisco within the Lake Merced area.

So basically, this project is going to be doing a couple of things.

We've been working with Daily City on this for a long time.

I've been working on this since 2012.

Daily City operates the entire system, but the project goals of this are going to be a couple.

We want to try and reduce the flooding that occurs in Daily City and within the San Francisco area.

We also are using this opportunity to reconnect Lake Merced to its previous watershed and divert some of that stormwater into the lake.

That gets us a couple of benefits.

We are able to restore lake levels that have been impacted by drought conditions and also the fact that for San Francisco, we have a combined sewer system.

So stormwater does not flow into the lake, it flows to our treatment plants.

The only recharge the lake has right now is basically what falls on it when it rains, so just direct precipitation.

So this will help us manage the lake levels and raise our lake levels.

Lake Merced is an emergency water supply for the city that we would use for firefighting and non-potable supplies during emergencies.

This allows us to increase that supply.

It also provides us a critical recharge to the underlying groundwater basin.
