Recommendation to Amend the Contract with Clean Lakes, Inc. to Increase the Contract Amount by $99,123.90, Including Contingencies, for Vegetation Management, Debris Management, and Water Quality Monitoring for the Southshore Lagoons, for a Total Contract Amount of $499,719.20. (Public Works 351)
Recommendation to amend the contract with clean lakes to increase the contract amount by 99,000, including contingencies for vegetation management. Is just a question. So if you answer it, then I guess we can move on. These are the lagoons that back in the summer there was a lot of unpleasant aromas that came out of these lagoons and we received a lot of complaints. There were signs during the 4th of July parade and so on and so forth. So I wonder if you can just address what, if anything, we can do about that and if this contract is something that will help impact. Shore for that particular by the way, I've Liam Garland with the Public Works Department for that particular question, I'm going to turn to our odor expert, Aaron. Aaron Smith, our public works coordinator. That's not a title I've had for years. I'll take it. So the aroma that we're speaking of is in the park, Otis kind of South Shore area. A little more pronounced this year than I think in past. Couple things at the edge of Park City, at the shoreline. I think a lot of you might have noticed large excavators there. So there's a separate project that's going on that's being administered by the East Bay Regional Park District called the Groin Extension. So the groin is that cement structure that goes out into the water. It's a it's a. Crown Memorial Beach is a human made beach. And so it requires structures to keep the sand in place, so it prevents the migration of sand downward there, extending that growing project, which requires the deep digging and the exposure of decomposing matter, and that causes the aroma that kind of mucky base smell so that this mucky, mucky, yeah. That this year is a little bit different than in prior years. And that commenced in mid-summer in regards to lagoon three. So we have five lagoons that run from. West to East Lagoon three is the one that has the end at the Park Goodison intersection. That one in and of itself has had its own challenges and. The design of it. Each lagoon flows from one to the other and the outtake pipes for lagoon three that has a an area that we call the armpit because it's past the outtake pipes. And so the water normally would flow through and you have moving water that covers up underneath lagoons they don't smell. So there's this area that's called the armpit that the contract that you guys are speaking of has been doing additional cleaning efforts, as well as our maintenance staff to address the accumulation of the debris. Our engineers are also looking at additional dredging of that material. There was some attempt to do that in the past and the Regional Water Board had put a stop to that due to some chemicals that were found in there. But we are pushing forward on trying to re dredge that material out. Typically when the lagoons are high and the material is covered, the smell is not there. It's when the lagoons are lowered. So also adding to it, we had some atypical construction projects this summer that we needed conducive groundwater conditions, so we lowered the lagoons in the summer again, causing the aroma that was noticed by citizens. Okay, so can we tell our constituents that next summer will be better or worse or the same? I hopefully our maintenance efforts will decrease the smell. We don't have intentions to lower the lagoons in the summertime unless some unforeseen conditions allow for it. I don't have a tentative date on the dredging. I think there always will be aroma. We live in a salt marsh bay environment. We're always going to have some level of smell, but I think we're giving it our best efforts from a maintenance perspective to reduce it. But. Thank you. QUESTION Well. Vice Mayor. If if if your intention changes with regards to lowering it next summer, will there be a process for notifying the nearby neighbors because it was a chief concern for many of the people living nearby? Yep. And we heard the citizens concerns. We actually established a website on the Public Works page just dedicated to the South Shore Lagoons, where we post any upcoming lowering dates. We also have an email distribution list that we're able to send out any notification for lowering schedules. Move upriver. A second. Did any of the council members have comments? I wanted to share that. During that time, myself and staff members met with many of the concerned citizens. We held at least one meeting and they I think you were there and we came up with an email list as well as some ideas to work with the community . So there was progress made. So I want to thank staff for participating in that. Thank you. All right. All those in favor. My motion carries unanimously. Thank you to EFF member. I pulled F and G kind of together. So it was just more of a kind of another update about the same area because that's Park and Otis. And if you could give a brief status update on where we are on the sewer replacement because during periods of heavy rain it was last week, we still see a lot
