San Francisco, CA 94102
I. Roll Call
Natalie Bonnewit, Nathan Brennan, Joanne Desmond, Heather Gallagher, Chrysanthe Gussis, Liz Hirschhorn, Karen Knowles-Pearce, Tim Molinare, Atta Pilram, Jesse Tepper. We have a quorum.
II. Approval of Minutes
The minutes were approved with the suggested addition of Dan Fedder as last name of presenter from Wilson Meany, and the clarification in item 4P-Question that the soil which is replaced is clean soil.
III. TIDA Staff Updates
- TIDA Board
Couple of items at BOS right now and a few items coming to Budget & Finance office.
Received Subphase Application comments back from city agencies. Received 47 comments back in total, so this is demonstrative of familiarity of the program and is good progress.
Demolition contractor is starting to work on the Brig. Causeway work is waiting for delivery of light fixtures, to be installed, then will shift traffic.
Contractor was scheduled to start moving soil into Phase 1 area, but holding off this week due to rain.
Estimate 50 days of continuous soil transport to expand the surcharge. Will entail moving the entire soil stock pile. About to submit to the City the area behind the Chapel is complete and then will move that soil to another area.
There have been five power outages on the island, most of an hour or two. On Presidents Day there was a 13-hour outage due to a fault in a line which took time to discover.
There has been a lot of stepped up communication with PUC about that outage. If their fix hadn’t worked, the City was considering opening a warming shelter.
Will be getting information to residents about how to subscribe for alerts for emergency and warning situations.
The Mayor’s Office has hired someone to serve as Housing Coordinator – their charter is to look at the review of major programs and see how the city can better support the review of those projects. Liz has been working with that team to try to expedite these kinds of issues.
On March 26th, there is on island RAB meeting.
On April 6th, the Department of Children & Youth will be hosting an event on the island with information about upcoming programming.
There will be a poster session before the on-island TIDA Board meeting in April.
- Development Schedule
- NAVY Environmental Program
Nathan sent out a report which is included here, there isn’t much change since the last one. A group has sued the Navy because they didn’t think the Navy complied with information they requested via a FOIA process. That will take a while to play out.
TICD working with the Navy to do filings for the dry cleaning (Site 24) location. Might be able to transfer in mid-Summer.
- Cleanup Controversy: On February 19th the Public Employees for Environmental Responsibility, PEER, sued the Navy for records and information about the Treasure Island cleanup. PEER filed a Freedom of Information Act for this information on November 1, 2018 and said they had not received a timely response. Although much of the TI radiation scanning and cleanup has been done by different (from Hunters Point) contractors, evidently some was done by Tetra Tech EC. For Hunters Point, the EPA, CAL DTSC and the Navy are continuing to work on defining the issues and redo the testing, sampling and clean-up. CDPH has tested the newly developed housing area and other in-use areas at Hunters Point. As noted before Treasure Island did not have the shipyard facilities or work history like Hunters Point. The Navy continues having a facilitator, Marsha Maloof, to help get everyone's comments in the RAB Meetings.
- NAVY Staffing: Dave Clarke continues as the Lead Remedial Project Manager. Temporarily the BRAC Environmental Coordinator for Treasure Island is Reginald Paulding, he transferred from a Navy environmental project in San Diego while a new BRAC EC is hired (in progress).
- 2018 REVIEW: Treasure Island Cleanup costs through FY 18 are $285 million. The budget for FY 19 is $4.8 M with an additional $5.1M needed beyond FY 2019 for completion of cleanup. Most CERCLA cleanup work in 2018 was completed in Site 12. In the Petroleum Program two underground storage tank, UST, sites remain in Site 6 with expected closure in 2019. Another UST to be removed and the site closed in 2019 is east of site 20, probably associated with building #224, which was demolished in the late 1950's. A Five-Year Review will be completed for Sites 6, 21, 24, 27, and 30 in 2019. The reviews are completed on sites that the remedy has been selected or cleanup action completed but the site is not closed because of required monitoring and/or land use controls. Five year reviews continue even after the property has been transferred. They ensure cleanup work remains adequate to protect public health and the environment.
- Finding of Suitability to Transfer, the schedule for the remaining transfers of property to TIDA is: FOST 8 - parcel 24 in 2019, FOST 9 - parcels 2, 6, & 32 in 2020 and FOST 10 - parcels 12A, 12B & Navy Retained Sites (mostly used for contractor staging) in late 2021.
- Site 12 the Housing Area: The scattered (forty-one) "small" soil removals project on the northern end of Site 12 is going forward. We are about 25% complete at this time. Each of these digs are expected to be completed in one day. They are mostly 10' X 10' and 1' to 5' deep. Ongoing preparation for the removals included sampling the sites to establish the contamination boundaries. The contractor prepared a soil screening pad on Site 32. All impacted soils are spread out on controlled-contained test bed for roll over radiological detectors. Any radiologically contaminated soils are put into specially designed, closed and sealed bins for disposal at a certified land fill (usually in Utah). All radiological contamination is controlled by the Navy’s Radiological Affairs Support Office (RASO). All trucks go through radiation scanning portals before leaving the Treasure Island site (and when entering landfills) to ensure no radiologically contaminated soil is disposed of improperly. The remaining soil is contaminated with other chemicals (including lead, benzo(a)pyrene, chromium, PCBs, pesticides, or dioxins) and will be disposed of at approved landfills.
- The Navy is still preparing to demolish buildings #1126, #1202, and #1127 to clean up soil below the foundations. Building demolition includes asbestos cleanup, appliance recycling, and proper disposal of wood with lead paint.
- North Point Area: The Navy is preparing for an approximately 4,000 cubic yards removal in the old solid waste disposal area (SWDA) that includes creosoted timbers, all removed soil will also be scanned for radiological contamination. This dig will remove soil under a portion of Northpoint Drive which will be repaved after completion. The ground water monitoring wells are tested on regular basis to ensure cleanup is meeting required goals. All the NAVY contractor's trucks will have a large numbered green sticker, to make them easily identifiable among the extra truck traffic generated by the TIDA redevelopment project.
- Bayside Area: The contractor is mostly done.
- Westside Drive Area: The Navy will process a new contract for the next (and final) phase of Site 12 clean up (solids waste disposal).
- TPH/Arsenic Cleanup Gateview Avenue Area - monitoring: The soil cleanup for this site is complete, monitoring will continue to ensure the removals and treatments meet site cleanup goals.
- Site 6 the old Fire School, Soil Removal Clean Up AND Emerging Contaminants PFOA/PFFOS Perflourooctanoic Acid/ Perflourooctane Sulfonate: The site's nine ground water monitoring wells will be sampled quarterly and tested to confirm site's condition and cleanup to date. This will continue for 2 1/2 years. The Navy recently had the sites well tested for Perflourinated Compounds (PFC) which are a component of firefighting foam and are considered an "emerging" contaminant by the EPA. The EPA has not yet set a standard that can be used for a cleanup goal. The EPA has established a Lifetime Health Advisory level at 70 parts per trillion (ppt) for drinking water. (No ground water on TI is to be used for any purpose, all water is supplied by the City’s Water Department by pipeline from the City over the Bay Bridge.) The Site 6 samples showed PFAS concentrations ranging from 124 ppt to 22,300 ppt. The Navy and CAL DTSC continue waiting on guidance from the EPA.
- Site 23, YF3 under assessment: This site on Yerba Buena Island had a heating plant, fuel tanks (including a 10,000 gallon tank) and fuel lines above Clipper Cove, and onto two piers that ran out into Clipper Cove. Samples on and offshore have been collected and were processed for the BERA (Baseline Ecological Risk Assessment). Currently CAL DTSC and the Water Board are reviewing and commenting on data and analysis in the draft BERA, this document defines the contamination present, the what, the where, and the cleanup actions that might be required to protect human health and the environment.
- Site 24 the old Dry Cleaners, Remediation: After 20 years of bioremediation, the majority of the dry cleaning solvent plume has been degraded to non-carcinogenic compounds. Monitoring and sampling will continue on a regular basis tracking the three remaining small pockets of contamination. These three spots all lie outside TIDA's planned footprints for future buildings. The sampling of ground water and soil gas samples will continue for two to three years to ensure cleanup goals are met.
- Restoration Advisory Board (RAB) Meeting: RAB meetings are quarterly, held on Treasure Island, the most recent (December) meeting was held in Building 1. The first meeting for 2019 is scheduled for March 26th. Please check the Navy website http://www.bracpmo.navy.mil/NSTI for confirmation of the meeting time and location and for more information about Treasure Island.
IV. Election of CAB Secretary
Becky Hogue has been elected (in absence) but we look forward to seeing her next time.
V. Parcel C3.1
Representative from Mercy Housing presents. See presentation for full details.
They have a parcel which is a partnership with Catholic Charities. They will be hosting 135 units in total (including a managers unit). Currently trying to figure out how to allocate different unit sizes. Worked with TIDA to submit grant application under Affordable Housing and Sustainable Communities grant program. It would be roughly $20 million and some would include some funding to go to the bus service. Working with architect Paula Taggart.
Question: Is that money just for those residents? No, there is funding for the building, but also for AC transit buses, bike paths and ferry plaza improvements benefiting all residents.
Comment: This is the first 100% affordable building that we discussed. There will be many more units, but this is a milestone for the CAB to reach this point.
Question: What happens at the ground level? There is a lobby and garage and resident services. Courtyard is second level. Nothing below ground. The lower side along shared public way is at the 40 ft. height limit.
Question: Are these some of the units that will be shared with the eligible candidates who were displaced? Yes, some of them that qualify.
Question: What is the earliest people could move in? March 2022 (if everything goes reasonably well.)
VI. Treasure Island Geotechnical Improvements
See presentation for full details. Presenter from ENGEO, Uri Eliahu.
Island was built on a sand shoal. Showed photos of how the island was filled.
The fill is susceptible to seismic tremors and liquefaction. The mud is the exact opposite. To stabilize we have to address both levels and do it differently. This is the surcharge that Bob Beck spoke of earlier. The water in the mud could take a very long time to squeeze out. In some places (80 years later) that water is only now starting to settle out. They are using wick drains to accelerate the process, using variable spacing depending on the timing needed.
Maximum settlement from the initial construction of the island is around 7 feet in the NW corner. May range from 10 feet to 5 feet depending on which part. It was level when built, but now is lower to the north.
To accommodate for sea level rise, the south of the island is approximately at the desired elevation. The south end won’t end up any higher than it is, but they will need to add fill so that as it settles it will return to approximately the same depth as now.
Question: Are these tried & true methods for this kind of geotechnical work? Yes some of it is using new proprietary Japanese vibro-compaction technology, but is built on processes that are used all over the world.
In 2015, two test sections were compacted utilizing vibrating compaction. It delivers a lot of energy into the ground. When you are standing near it, you can really feel it. The tests were successful. The compression met or exceeded the results we were looking for.
The fill can be improved using this technique but not the shoal. Did a lot of research and different tests, including simulating a 125-year earthquake, to find what might work with the shoal. It has lots of microbiological components which make it resistant to the compression. After analysis, concluded that given a 125-year earthquake, it may settle about 1 foot at 150 feet from the shoreline. Given that information we have now changed the ground improvement strategy. From vibro-compaction, to wicking, to deep soil mixing along the ferry and marina areas. So far about 70% of the wicks have been installed (1000 miles of wick drains) 50% of the first phase area is complete with vibro-compaction, about 40% has had the tamper treatment.
Question: How are we progressing compared to the expected timeline? Started late, but comparatively adjusting for that, we are about 2 weeks ahead of what was anticipated.
Question: How does ground treated influence building foundation design? For the buildings, they can be built on shallow foundations. For the taller buildings the foundations will need to go through fill, shoal, mud, and all the way to the stiff clay. Beyond that threshold, it has to go to bedrock, which is a very long way down. May end up with some foundations that are approaching 300 feet.
Question: Re: vibro-compaction & tamping, are they doing that in one step or two? It looks like it’s all being done with 1 machine. The hoppers that are on the machine are sort of a hybrid that forces sand down while doing the compaction. They will still come back and tamper down the top levels which gets disturbed in this process.
Question: How is this different than the sinking sidewalks in Mission Bay? How will this be better? Mission Bay doesn’t have the hydraulically placed soil. The bay mud it’s built on releases water when load is placed on it, then it doesn’t return. They did surcharge with wicks, but only on the building pads. They could surcharge that area, but couldn’t do that to the streets because they were existing. So generally, the problems there are at the interface between the streets and the buildings. On TI we have the luxury of surcharging everything. Not just to loads for buildings, but for another 1000lbs load on top of that.
Question: Any relationship between Richter scale and 125-year earthquake. The building code is on return rate not on Richter scale. The 125-year is a non-collapse situation. For comparison, it’s a little over 8 on the Hayward or 7.2 on the San Andreas. It’s a 1906 on the San Andreas that is closest to the site. This would be stronger than that actually. Also have to look at probabilistic scenarios. More likely to be a combination of smaller impacts and other factors.
Question: After all this work is done, does another field test need to happen to confirm that it accomplished what was intended? Not necessarily because they developed a tested method spec, but for each building there will be a 3rd level test and subsurface exploration.
VII. Parks & Open Space Plan
See presentation for full details. Presented by Bob Beck.
This is a high-level refresher about what will be happening. 290 acres of open space. More than 150 is agricultural farm, northern park & sports fields.
Question: Will there be any buildings on Pier 1? Could be, but likely something small. Trying to figure out how to get people to go out there and use it besides just that it juts out into the water.
Question: About the recreational fields, are their approximate or definite coordinates of where they will be? Yes. That is available, it’s near Avenue H and the YMCA, but final layout and programming of fields is to be determined.
Farm will be about 25 acres, so that is pretty sizeable. Would be an actual full production urban farm with room set aside for community garden, and would hopefully be tied to grocery or restaurant on the island.
VIII. Future Agenda Items & Role of the CAB
Bob displayed the CAB bylaws which maps out the purpose. See official documents for details. We are continuing in the process as defined. 2011 was a culmination of a big part of the process, from planning and now we are progressing into implementation.
Comment: Now that we are back to a regular schedule. It’s clarifying for us.
Comment: As an island resident, Atta has found that he is in the role as messenger.
Comment: Good to look at the phases we are in and what expertise is needed on the CAB.
Comment: An example of how we might proceed… toll policy is coming up and if we don’t talk about that in enough time, we will have missed it. It seems there have been some topics that we don’t get to in time and then the process has already passed where we could be helpful or provide input. Need to structure meetings to take that into consideration, especially if they want an official recommendation or endorsement from the CAB.
Comment: There was a discrepancy between the toll model projections and now what they are expecting. Was expecting TMMA to come back and show us new models and updates before the CAB can be comfortable approving. Atta invited Jay Wallace to do a presentation on the Marina at the Yacht Club on June 1. Atta would like to invite the CAB to attend if they want to. There are lots of rumors and want to get everyone on the same page and figure out how to support each other and help work through any remaining opposition.
Comment: Since there is some contention, it would be good to have a fact sheet that outlines how we got here to set the historical record and help do a lot of education around the process so far. Yes, that is probably doable, and likely that TMMA is working on a similar.
Comment: Why was the CAB taken out of the plans for the Marina? Why was it taken to be just between Jay and the Sailing Center? The new Marina is the whole reason that Karen joined the CAB. It’s now a bit more complicated because there is parking and access concerns. TIDA can bring back some of the land-side updates.
Bob will talk to Jay Wallace and we will get him on the agenda.
Comment: Can we get another update on where we are with the Art process? Yes, it’s about time for that.
Jim Hancock from the Sailing Science Center. They are having an event on Thursday night. They will be giving a presentation at the Corinthian Yacht Club on March 7th at 7pm in Tiburon.
