Hello Commission,
We wanted to share a letter with you that came to us, also this article that appeared in the Chronicle recently. In my completely unscientific though unbiased survey when asked no one wants artificial turf. How can we move this topic to a commission meeting? PUC has a responsibility to fully understand the issues and make a public decision.

Thank you,

 Dear Commissioners,
My name is Amelia Jones, Senior Engineer in TRC’s San Francisco office and national leader of our Emerging Contaminants of Concern research group. I am writing regarding the February 20thRecreation and Park Commission plan to renovate the baseball and softball fields at Crocker Amazon with artificial turf. I am concerned about the public and environmental health risks associated with this approach.

Artificial turf often uses recycled tire crumb rubber as infill, a known source of 6PPD and its transformation product 6PPD-quinone (6PPD-q). 6PPD-q is an emerging contaminant already regulated in Washington State due to its lethal toxicity to salmonids ( Tian et al. 2021
). USEPA has issued non-regulatory screening levels (USEPA, 2024), and studies have shown 6PPD-q in human urine, serum, and cerebrospinal fluid (Du et al. 2022; Zhang et al. 2024; Fang et al. 2024) as well as evidence of organ damage and fetal transfer in mammalian studies (Zhao et al. 2023; He et al. 2023; Zhang et al. 2024). While more human research is needed, current literature strongly suggests significant health concerns.

TRC recently advised one of our clients, the Presidio Trust, on a similar project and determined that the health risks from artificial turf were unacceptable and worked with them to deliver a safer alternative. I would be glad to support the Commission in evaluating the Crocker Amazon project, formally or informally, to ensure a solution that protects both the community and environment.

As a regular user of Crocker Amazon for the past eight years, I fully support long-overdue improvements. However, I urge the Commission to avoid artificial turf and tire crumb rubber infill, which also contribute to microplastic pollution.

Natural, low-maintenance grass remains the safer option.

Please do not hesitate to reach out to me if you would like to discuss further. I've included some informational resources, linked below, that provide more detail on the risks associated with 6PPD/6PPD-q, and establish the precedent for phasing out materials that could introduce this contaminant into our environment.

Hello Commission,
Thank you for your response. Dan and I are familiar with each other. We still are hopeful to finally understand how the artificial turf is recycled and review audited statements from the recyclers that RPD uses.

Dan is also aware of PUC’s concerns (see below). We feel PUC has a strong interest in understanding what RPD proposes. The recent report from San Francisco Estuary Institute finding globally high levels of microplastic and nanoplastic in our water supply is cause for concern.The fact that PUC won’t begin testing for plastic in our drinking water until 2026 is alarming.
https://www.sfei.org/sites/default/files/biblio_files/MicroplasticsExecutiveSummary.pdf Covering an open field directly above a watershed with 200,000# of plastic is irresponsible and reckless. The PUC has a responsibility to insure a safe water supply for the citizens of San Francisco. We strongly feel the PUC commission should have a public hearing to discuss this very important matter.

Thank you,
Wesley Saunders

Dear Dan,
I am head of the SFPUC Real Estate Services Division. I hope this email finds you well.

As you may know, the SFPUC has jurisdiction over the land used by RPD for the Crocker Amazon playing fields and other recreational uses.

We recently learned about the proposed baseball and softball field renovation on the SFPUC’s Crocker Amazon land. https://sfstandard.com/2025/05/27/sf-giants-crocker-amazon- microplastics/
The SFPUC’s In City Project Review Committee needs to vet the project to determine if it has any material impacts on the SFPUC’s land and or utilities and to see if it complies with SFPUC policies. To that end, please submit an In-City Project Review Application with related attachments to the SFPUC as soon as possible. The Committee is comprised of representatives from several divisions and will review RPD’s application at an internal meeting and offer written comments. You do not need to attend the meeting, although you are welcome to do so.

Here is a link to the SFPUC website where you may find more information about the Project Review process and download an application. www.sfpuc.gov/project-review-SF Please contact Marisol Wauters with any questions. She runs the Committee and is copied on this email.

We look forward to receiving your application at your earliest opportunity.

Finally, we note that RPD also has a playground improvement project. The RPD website does not mention the name of the project manager. Can you please provide us with the project manager’s contact information and forward this email to him, her, or them?

Dear Mr. Ritchie, Mr. Prather and San Francisco PUC Commission; On the SFPUC Commission Meeting Agenda webpage, there is a Notice of Public Hearing for Tue, Sept. 9th, 2025 at 1:30 PM.

The notice was posted Aug. 19th and is available from this web address: https://www.sfpuc.gov/sites/default/files/PH%20Notice_2025%20Public%20Health%20Goal%20Report_9.9.2025_3.pdf .

According to the notice, the agenda items and related files, likely including the 2025 Public Health Goal Report, will be available 72 hours before the public hearing however are not yet available.

At this time, the Public Hearing has an incredibly short notice and 72 hours is not sufficient to assure that the threat to our drinking water, as well as other threats to public health and safety, are adequately covered by your "Public Health Goal Report".

Along with the currently planned Sept. 9th, public hearing, we are requesting the commision provide an additional continuance of the public hearing to the first meeting in Oct. to provide sufficient time to gather information needed to address the critical concerns to our Public Health.

In the 2010 Sewer System Master Plan San Francisco PUC, San Francisco legal and elected officials determined that there is no reason to address sewage discharges from the public sewers into public streets, into private homes and businesses, as well as onto our parks and open spaces. Please see:
“TECHNICAL MEMORANDUM NO. 405 REGULATORY CONSIDERATIONS FOR WET WEATHER COLLECTION SYSTEM BACKUPS”.

As pointed out in the San Francisco Bay Area Regional Water Quality Control Boards public announcement of the Sept. 2021 Cleanup and Abatement order: "Sewer overflows contain pathogens and other pollutants that pose human health risks and threaten groundwater quality."
Friends of Mission Creek is concerned about the public health implications of discharges from San Francisco PUC's combined sewage system including the impact to the groundwater drinking supplies of San Francisco County, San Mateo County, and the surface watersheds of the National Park Service's Lobos Creek. This includes the lands around Lake Merced, Pine Lake, and other areas where the surface waters are likely to easily intermingle with the groundwater aquifer. The western sewersheds of San Francisco are above the Westside Groundwater Basin, a source of drinking water shared between the City and County of San Francisco, and the cities of San Mateo County including Daly City, San Bruno, the Town of Colma and potentially Burlingame and South San Francisco. The Lobos Creek watershed is a drinking source for the Presidio of San Francisco including the National Park's Golden Gate National Recreation Area and Presidio Trust.

San Francisco's sewer system has many locations throughout the western watersheds that are substantially undersized, allowing combined sewage, including the sanitary wastes from the residents of San Francisco, to discharge out of the public sewers. As pointed out below, in many cases the downstream sewers are not sized adequately to convey the sewage carried by the pipes upstream. In these cases, the sewage backs up and exits the public sewers, spreading contaminates across the surface. In the email below, SFPUC's Sarah Minick responded to residents of Ingleside Terrace who were attempting to point out the increased concentration of sanitary wastes discharged from the sewers into in their neighborhood due to the Balboa Reservoir Project which will increase the amount of sanitary wastes upstream from the known undersized sewers on Ocean Ave. Although most of sewage discharged may eventually return to San Francisco's combined sewers as the City Attorney attempts to point out in the Tech Memo discussed above, in the meantime it will also be entering the soil mass and slowly flowing into the groundwater of the western watersheds. Along with the Ingleside/Ocean Ave problem, there are many other instances of San Francisco's sewers discharging onto the surfaces above the aquifer, into the lakes which interact with the groundwater and surface waters of Lobos Creek however. It appears that the problems include sewage geysers in the area around Lobos Creek, as well as broken sewers and blown manhole covers, discharging sewage into the watershed above the Presidio Drinking Water treatment plant. As the Fort Point Brewing Company points out: "It's all about the water ". According to documents from the 2010 SFPUC Sewer System Master Plan, there have also been numerous issues with the sewers flowing down from Lake St. into the Lobos Creek watershed, eventually collecting in the large Richmond Tunnel.

These documents also clearly point out problems around Lake Merced, Pine Lake and San Francisco State University's campus near Lake Merced. Discharges that are likely to seriously impact the Westside Aquifer include blown manholes on the box sewer crossing Lake Merced, sewage discharges around the parking garage at San Francisco State University, discharges from the sewage pump station into Pine Lake among others. The untreated sewage may be bringing contaminants into the surface waters of Lake Merced and Pine Lake as well as into the aquifer which is then served back to San Francisco residents through the westside "blending" program as well as with our neighbors to the south who also rely on that aquifer for a portion of their drinking water.

We also are requesting SFPUC provide additional documentation to help understand the potential risk of contamination and the steps SFPUC has taken to protect the public health of San Francisco residents currently sharing in the "water blending" program, the users of the Predio's drinking supply and our neighboring cities and water supply agencies who share the Westside Aquifer for their drinking supply. The goal will be to help all of us (Including the state and federal agencies and regulators) understand the how the known discharges from the public sewers may be potentially impacting the groundwater and surface water drinking water supplies including:

1. Please provide all documentation of known and potential discharges from the combined sewers into Lobos Creek. The 2010 Master Plan documents specifically list this as an area of concern. Please include all notifications to the Presidio Trust and National Park Service notifying them of potential contamination of their drinking water supplies. IF SFPUC has addressed these issues with capital projects or annual maintenance funded projects, please provide all engineer studies and design recommendations, conceptual engineering reports and alternative analysis reports for the project SFPUC may have undertaken to address these issues.

2. Please provide all reports and studies regarding the sewage backups, discharges,and pumping failures leading to combined sewage spills into Pine Lake. Again, as above, any public notices of potential contamination provided to the public users of the park facilities around Pine Lake, notifications to SF Rec Park, etc. If any projects have been undertaken to address these problems, please provide the engineering reports as above.

3. Please provide any documentation of sewage spills into the area around Lake Merced including onto the grounds of San Francisco State University, the Parklands around Lake Merced, the areas upstream within the immediate vicinity of the Westside Aquifer including Park Merced, Brotherhood Way, Junipero Serra Blvd, especially including at the low point on the frontage road east of intersection with Lyndhurst Drive. As above, also provide any notifications issued to the other water supply users of the Westside Aquifer, engineering studies etc. of attempts to mitigate these discharges.

Others on this email may also find this issue important, and we will also attempt to inform the neighboring groundwater supply users of our concern so that they can also attempt to determine their water supply users potential exposure to contaminants carried by the SFPUC's combined sewers.

Thank for you your attention to this matter

Dear Regulatory Staff and Board Members
Friends of Mission Creek (FOMC) is a group interested in the sewage problems in San Francisco, primarily focused on unnecessarily excessive raw sewage discharges into Mission Creek and other areas of water contact recreation around San Francisco and the impacts to public health of raw sewage discharged into our community. FOMC members have also worked with various other groups around San Francisco concerned with the lack of regard for public health exhibited by SFPUC over the last 15 years. FOMC would like to thank the Ingleside residents with Stop Flooding Ingleside Terrace (StopFloodingIT) and Solutions Not Sandbags for including us in this discussion. A pdf of this letter is attached if inline images or links are not working. Please let us know if you have any problems accessing the linked documents.

FOMC has reviewed Ms. Minick’s response for SFPUC and would like to make the following comments about some of the problems illustrated by Ms. Minick’s response and the City’s confused public policy:

1. Ms. Minick missed the chance to reply to Solutions Not Sandbags follow up email [1] reminding all that the issue to be addressed was the increased sanitary flow which will be discharged onto Ocean Ave., polluting the streets and sidewalks of Ocean Ave then flowing downhill to the residences of Ingleside Terrace.

2. “The SFPUC has worked diligently with other City agencies and the designers and developers of the project over the course of the last 10 years to require that the project limit its flows to the Ocean Avenue sewer during wet weather events so that the stormwater flow conveyed after project completion is the same as is conveyed before the project is built.” It is unfortunate that Ms. Minick implies that SFPUC is concerned about maintaining the same flow as before the project was built.

According to San Francisco’s “OneSF”, Office of Resilience and Capital Planning’s 2024 Capital Plan the Balboa Reservoir Project will add an additional 1,100 housing units[2] immediately upstream of the undersized sewer on Ocean Ave. between Plymouth and Frida Kahlo Way (Phelan) that StopFloodingIT refers to. This will add an approximately 3,000 new residents immediately upstream from the known sewer system deficiency. FOMC would like to emphasize that building new housing in SF and the entire bay area is a much needed (and long delayed) effort and FOMC (and we believe StopFloodingIT) are NOT advocating against the project. Nor does it appear they are asking San Francisco to address “flooding”.

The problem that must be addressed is that the new residents will be using the sanitary facilities in the new apartments during rain storms.

When added to the estimated 6,500 residents already upstream of the undersized sewers, their sanitary flow flushed during rainstorms will increase the concentration of human feces and other waste typically disposed of by San Francisco’s residents such as toilet paper, urine, menstrual products, condoms, grease etc. by over 50%.

As shown by photos[3] following similar sewage backups and discharges (also euphemistically called “excursions” and “sewer overflow from combined system” or SOCS in the NPDES permits[4]) the geysers of sewage coming out of the public sewer manholes carry this sanitary waste onto the public streets and sidewalks, public parks and into the private homes and businesses of San Francisco. If Ms. Minick and those that set such policies in San Francisco chose to have the project developers store the sanitary waste during storms, this would help address the impacts to public health and safety to those downstream that the residents of Ingleside Terrace are trying to bring to the attention of San Francisco officials.

3. The Balboa Reservoir project does not include upgrades to the Ocean Avenue sewer. However, the project does include requirements for the developer to install large stormwater storage pipes and weirs that will temporarily store and convey the increased stormwater flows from the project. These requirements have been crafted specifically with the capacity in the Ocean Avenue sewer in mind. The SFPUC and other City agencies have stewarded these requirements over the course of project development to ensure that they are delivered. These requirements are documented in the Balboa Reservoir Infrastructure Plan , dated June 12, 2020:
“Due to existing capacity limitations in the Ocean Avenue combined sewer system, the proposed Project will not increase peak stormwater discharge from the project site during the 5-year, 3-hour and 100-year, 3-hour storm events, including stormwater flow amounts equal to the estimated project peak sanitary flow, as a requirement of the SFPUC for project implementation. Onsite detention and retention will be provided to limit the peak discharge to existing conditions.” (Balboa Reservoir Infrastructure Plan, 2020, p.82)
It is important to point out some confusion amongst San Francisco officials about the storms which routinely impact San Francisco. It is very rare for a substantial rainstorm to last 3 hours or less. Our typical winter storms are not the fast and furious convective cells or “thunderstorms” seen in the US Midwest or the summer monsoons of the American southwest. Our winter storms are large “atmospheric river” events or strong “extra tropical cyclones” both of which can last 12 to 36 hours. Frequently these storms are followed by unstable air with convection cells bringing short duration, high intensity rainfall immediately after the cold front passes [5]. Within these storms there will be
zones of convergent and overturning air leading to waves of shorter duration, high intensity rainfall during longer periods of nearly continuous rainfall. Using San Francisco’s relatively small “3 hour storm” as a design criteria will lead to very small storage volumes as the total depth of rainfall predicted in the 3-hour 5-year storm is only 1.22” in 3 hours. This is less than what we’d expect to see every 2 years in 6 hours or every year at 12 hours (fig 1 below). Similarly, the policy makers use the 100 year 3-hour storm which is 2.16” in total depth. This is the same depth as the relatively frequent 5 year 12-hour storm or the common 1 year 24 hour storm. Using onsite storage, the storage chambers designed to meet the relatively low bar of the 3 hour storm will frequently fill in the relatively common longer duration storms.

Once the storage is full, because of the “weir” design, it would appear that additional rainfall will bypass the storage chambers and increase the loading downstream, again leading to increased sewage backups onto the streets, now with a higher concentration of sanitary wastes.

Figure 1, from NOAA Atlas 14 Precipitation Frequency tables for the area of San Francisco new Mint

4. Ms. Minick, speaking for the SFPUC, goes on to point out: “the project will not increase the peak stormwater discharge to the Ocean Avenue sewer during storm events that occur statistically every 5 years or every 100 years.” A major problem with San Francisco’s reliance on the “5 year storm” is the confusion about how frequent the “5 year storm” actually is.

One might expect that the “5 year storm” would happen 5-6 times over 30 years, or 20 times in 100 years. Unfortunately, the methodology to create these statistics skews the actual frequency of relatively common or “low return period” storms (in comparison to less frequent, higher intensity events) over extended time[6], especially when using the annual maximum methodology to calculate return periods. The statistical frequency of short duration high intensity is also very difficult to calculate due to the relatively small area covered by higher intensity convective cells or convergence zones within larger storms. Peak intensities may impact an area as small as 200 by 200 yards missing rain gauges used to collect data to estimate return periods and long term historical records represent only hourly data and our information about shorter duration events is relatively recent, leading to problems tracking and calculating short duration, low return period probabilities.

5. “This offsets an additional worst-case scenario condition in which the project’s peak sanitary sewage flow occurs simultaneously with peak stormwater flow
”
Unfortunately this does not reduce the concentrated human waste and in fact this statement illustrates that the peak sanitary flow (ie human waste, toilet flushing, etc), comes regardless of the storms happening at the time. It is interesting to point out however that during different periods of the day sanitary flows are much higher than an average flow as the upstream households use the sanitary facilities more, and so when storms come during these times of peak sanitary flow, the concentration of harmful human wastes coming out of the sewers is even higher.

6. “The large stormwater storage pipes and weirs under Loquat Lane, Wisteria Lane, and Mayor Edwin M. Lee Avenue will be implemented during infrastructure construction which will either be concurrent or before building construction. The project will also be complying with the San Francisco Stormwater Management Ordinance (SMO), which will result in stormwater management strategies such as permeable pavement and rain gardens to manage site-level stormwater runoff. The stormwater management strategies achieving SMO compliance in the public realm will be delivered during streetscape construction. The stormwater management strategies achieving SMO compliance on the parcels will be built at the time of vertical construction for each parcel .”
The reliance on “storm water management strategies” is concerning here. SFPUC has already pointed out, in a 2018 report to the [7]
SFBRWQCB that green infrastructure and other similar approaches were limited in their impact, especially for “larger, more intense storms”.

This was in reference to the relatively small, frequent storms that happen 10-12 times a year leading to the combined sewer overflows, or discharges of raw, untreated sewage into the bay and ocean. If San Francisco is convinced that these types of features are limited in value, as they told the Regional Board, it is amazing that SFPUC would still insist that developers use these approaches in a performative attempt to show it is protecting downstream neighbors.

Figure 2. From BAYSIDE SENSITIVE AREAS REPORT
Ms. Minick points out that the stormwater strategies will be achieved “during streetscape construction”. This is even more alarming when one considers the overall runoff throughout San Francisco, as well as the upstream development is predominately driven by runoff from roof drains. This helps explain why SFPUC found green infrastructure inadequate to address sewage problems. Citywide, approximately ⅓ of the watershed catchments are city streets. This percentage goes up considerably in the more urbanized areas to the north and east. Most greenscape approaches attempt to address runoff from the streets with small areas of planting or (hopefully) more pervious landscaping soils.

Unfortunately, more than ⅓ of the drainage is rooftops. These are hard plumbed to the SFPUC sewer system by city plumbing code. Water at the much higher elevation of the rooftops will be quickly and efficiently passed into the sewers, with nothing to stop the flow from these higher elevations into sewers that, if properly designed, would limit surface runoff once they have reached their peak capacity. More than ½ of the flow in the sewers comes from rooftops but SFPUC has not made any attempt to address this.

7. “As climate change contributes to larger and more intense storms, residents and businesses can partner with SFPUC to take steps to protect their properties. We encourage Ingleside residents who have experienced flooding during heavy rains to reach out to SFPUC to see if they are eligible to apply for funding from our Floodwater Grant Program, which offers up to $100,000 per property to increase flood resilience
. “
Ms. Minick and the SFPUC point to the concern that climate change may be impacting the storm intensities, bringing “larger and more intense storms”. If this is the case, then the sewage being dumped into the streets, homes and businesses from the sewer backups will become more frequent. This should be alarming not only to the regulators, but to all residents of San Francisco who will be increasingly at risk of having their upstream neighbors sanitary sewage in their homes.

SFPUC has mentioned increasing storm intensities numerous times and has sponsored studies to put an academic air to this statement[8].

If SFPUC truly believed this was going to be a problem, they would be focused on addressing known system deficiencies such as the sewer on Ocean Ave which has been a known problem for decades (see figure 3 below, from the 2009 Sewer System Master Plan). Instead, SFPUC has chosen to ignore its own studies, placing its residents at increasingly frequent risk of exposure to raw sewage. Worse yet, SFPUC has chosen to continue to increase the size of upstream sewers such as the 2010 “Miramar-Wildwood” [9] sewer replacement project (figure
4), also called the “Cardinal Riordan Project”[10] which was initiated because of complaints of flow from the streets into the Cardinal Riordan High School track and football field[11]. This project was built to alleviate flooding upstream of Ocean Ave, putting considerably more flow into the Ocean Ave. sewer at Miramar Ave.although it was well known that the Ocean Ave. sewer was considerably undersized and prone to flooding (see figure 3 from 2009 and figure 5 from 2016, showing known sewage backups and apparently increased with the 2010-11 Miramar project.

Based on the Balboa Reservoir Project Infrastructure plan (figure 6), it appears that the Balboa Reserve project is likely to discharge sewage from the development on Ocean Ave, near Plymouth and Lee Aves, right in the area that sewage manhole covers have been observed having been displaced and geysers of sewage observed, figure 6.

Figure 3, “Hydraulic Grade Line along Ocean Avenue Sewer” from Aug, 2009 Sewer System Master Plan “TECHNICAL MEMORANDUM NO. 505, FOCUS AREA ALTERNATIVES ANALYSIS AND RECOMMENDATIONS FOR DETAILED DRAINAGE PLAN”. Areas of sewage backups causing geysers of sewage at golden arrows. Sewage levels are blue lines, surface is green lines, blue lines above green represent flow exiting the sewers.

Figure 5, “Storm Simulation” from SFPUC comments to 2016 email note that the annotation on the image is from SFPUC, attempting to show the Ingleside Terrace residents that the sewer in their area is sufficient and therefore SFPUC would not address the sewage backups upstream from them. Red dots appear to represent surcharging manholes.

Figure 6, Proposed Combined Sewer System, Fig. 12.1 Balboa Reservoir Infrastructure Plan. Page 84.

8. “In addition to the grant program, the City participates in the National Flood Insurance Program, which provides federally backed flood insurance for homeowners, renters, and businesses.”
This statement should raise several red flags for the federal regulators. San Francisco has decided to have the homeowners and businesses impacted by the sewer backups pay for their own protection from the sewage generated by their upstream neighbors but discharged due to sewer backups. To make this much worse however, the National Flood Insurance Program specifically excludes damage caused by “sewer backups”[12]. Congress, in enacting the NFIP appears to have specifically excluded sewer backups to prevent the use of the national program to subsidize poorly designed sewers.

The standard NFIP flood insurance policy states:

V. Exclusions,
D. We Do not insure for direct physical loss caused directly or indirectly by any of the following:

5. Water or Waterborne material that:

Backs up through sewers or drains.

If the upstream flow onto the street is primarily caused by sewage backups, and not generalized flooding, then insurance companies carrying NFIP underwritten insurance would properly deny claims. In the case of flooding in San Francisco, most of the water on the streets appears to have been carried by oversized upstream sewers, and only cause a condition of flooding once this flow hits the undersized sewers downstream. San Francisco officials are trying to avoid the consequences of providing excessively large sewers upstream by having private homeowners and businesses, along with the Federal Government, pay for the damage caused by San Francisco’s refusal to adequately design and operate its sewers. Attempting to have the federal government underwrite the risk of undersized sewers is likely abuse and misuse of the federal flood insurance program and likely to be found to be improper.

San Francisco’s policy approach, as promulgated by the 2009 statement that there is no regulatory reason to prevent sewage discharging into private homes
[13], and the 2012 policy set by Ed Harrington under Mayor Gavin Newsom removing all projects designed to mitigate the sewage backups from the SFPUC capital program[14], seem to tell the public that if the storm is a “6 year storm” and sewage comes out onto the public streets and into private property it is no longer a concern of the City. Over the last 15 years this has become an official policy of “every man for himself”, essentially blaming the victims of the sewage backups. This is best illustrated by the statements of Ed Lee, the much admired former mayor of San Francisco, designated by Gavin Newsom to replace Mayor Newsom[15] in 2011. Mayor Lee, after sewage backups on Alemany Ave. led to sewer geysers inundating Cayuga Ave. twice in Dec 2014 initially promised to take action to reduce flooding but apparently after being convinced the City was not required to do anything, back tracked[16] and subsequently took no action to address the known sewer deficiency even though he and his family lived immediately upstream of the Cayuga neighborhood where his sanitary wastes discharged into his constituents homes.

In an odd twist, under Mayor Lee, San Francisco again decided to upgrade sewers upstream from the known Cayuga/Alemany problem areas (and near Mayor Lee’s home) with the 2015-6 “Foerester Project”[17] in the Sunnyside neighborhood, which added an auxiliary sewer down Foerester St. This project was initiated to deal with sewage backups near the Sunnyside playground, caused by sewer upgrades upstream on Teresita Ave following 2004 storms. This is just one of many examples of San Francisco solving upstream flooding to address relatively minor problems with “sewer capacity” projects where increasing capacity is relatively inexpensive, without adequately addressing the downstream impacts to what San Francisco officials euphemistically call “low laying areas” where handling the flows transported by San Francisco sewers can only be handled by larger projects.

The problem on Alemany Blvd and Cayuga remains today, however is theoretically supposed to be addressed as part of the 2021 Regional Board Cleanup and Abatement order. In 2010 SFPUC appeared to be attempting to address sewage backups but since 2012 San Francisco has attempted to avoid responsibility for the self-created problem until forced to do something by regulatory action. Unfortunately, other areas impacted by similar sewage backups such as Ingleside, as well as the sewage now being discharged onto Marina Blvd and illegally into the San Francisco Bay have yet to be adequately addressed by California State regulatory agencies, under the leadership of Governor Gavin Newsom, whose policies as Mayor of San Francisco had initiated the lack of concern for public health and safety back in 2009 to 2012.

Figure 7, photo by SNS members of 3’ sewage geyser on Cayuga Ave. For more photos from these events see “Addendum to Regional Board” .Also note that this event was not reported as required by SFPUC’s NPDES permits even though a SFPUC vactor truck crew was onsite (left).

The City officials euphemistically claim these are “flood prone” or “low lying areas” and helped convince the press to use similar descriptions to help deflect public attention to the known sewer deficiencies. However the only flooding observed is geysers of sewage coming onto the streets and into homes and businesses, see Fig.7 and links provided. The City Attorney will deny all claims of damage[18] from these sewage spills and the SFPUC will claim that they can’t be held responsible for sewage coming into private homes and businesses, even though the source of the sewage is the system of drainage developed by San Francisco over the last 160 years. The pipes built by San Francisco quickly and efficiently carry the sewage down the hill, allowing the upstream residents to enjoy an incredibly high level of safety, much to the detriment of the downstream residents who must attempt to defend themselves from their upstream neighbors sewage. In these cases, the upstream users receive substantial benefit while harming the downstream residents.

San Francisco officials, instead of addressing the known deficiencies directly, attempt to deflect the concern of regulators and the voters away from their dangerous decisions. For example in discussing the October 24, 2021 storm that caused substantial damage to homes on Marina Blvd. after San Francisco chose to close the largest of 3 outfalls serving that area:
“The storm that struck San Francisco on October 24, 2021, was a 53-year storm, more than 10 times larger than our sewer system is designed to handle...It should be noted that this size storm far exceeds the capacity of any urban stormwater system. No sewer system, including San Francisco's, can reasonably be designed to manage this size of storm.” [19]
This is a rather odd statement since the national standard for flood protection is the “100-year” storm (which by the way is not 20 times greater as the author of that letter mistakenly claimed) and urban drainage systems designed to safely handle these storms are routine in both the United States as well as most of the developed world.

Even odder is the claim in the same document that the system provides the same level of service throughout San Francisco. This is easily proven false by looking at the 80% of San Francisco that has little to no rainfall collecting in the streets, nor sewer backups, during peak downpours. These areas enjoy exceptional protection because many of the City’s sewers are built substantially larger than needed, allowing the upstream sewers to continue conveying additional water beyond the capacity of the downstream system. This flow from the oversized sewers is the proximal cause of most (if not all) of the “flooding” in San Francisco. Throughout the City, where the sewers are properly sized, in a 6-10 year storm the pipes should be full and additional inflow from the streets would not enter the system. This unpolluted rainwater would gather in pools on the streets, typically around the catchbasins at the intersections, not entering the pipes which are running full. This is actually considered good design and is called “the major-minor system” [20].

The problem of San Francisco allowing its combined sewers to be a public health and safety nuisance has been an ongoing problem, dating back centuries. However, in the 2000s, after major sewer flooding in Feb 2004, San Francisco embarked on the Sewer System Master Plan, resulting in plans to address sewer backups. Unfortunately, the issue of sewer backups was found to have no legal consequences:
“Currently no regulatory requirements appear to apply to backups and outflows from combined systems that do not result in a discharge to receiving waters (Bay or Ocean).”
[21] With this finding, San Francisco PUC General Manager Ed Harrington, placed in charge of SFPUC in 2008 by then SF Mayor Gavin Newsom[22], decreed in July 2010[23] that SFPUC would not consider sewer backups in storms greater than the “5-year 3 hour storm”. With the lack of any consequences for sewage backups, Mr. Harrington then dictated in 2012[24] that SFPUC would remove all projects to reduce sewage backups, making the policy decision against concerns by SFPUC Commissioners.

With this 2012 policy decision in place, San Francisco has spent the last 13 years trying to justify allowing its sewage system to overflow into its residents homes. This led to the attempt by the US EPA to require California to address this obvious threat to public health and safety, leading to the Sept. 2019 letter from US EPA Director Wheeler to California Governor Gavin Newsom [25]. This effort led to some action by the
SFBRWQCB leading to the 2021 “Cleanup and Abatement Order” (CAO)[26], requiring San Francisco to address 3 specific areas of known sewage backups. Unfortunately, this did not deter San Francisco from not only allowing its sewer system to put its residents at risk, but to take the even more catastrophic action of closing the largest sewage outfall in the Marina District in 2021, leading to multiple catastrophic sewage inundations into the private residences on Marina Blvd. This same lack of concern for public health and safety has allowed San Francisco to proceed to place its residents in increased risk of exposure to raw, untreated sewage such as illustrated by Ms. Minick and SFPUC’s letter and their failure to address the well documented problem immediately downstream of the Balboa Reservoir development project.

Ms. Minick has a very difficult job here trying to convince residents whose homes are inundated with raw, untreated sewage that although the City refuses to address the known defect in their sewer system there is a silver lining in at least the City will attempt to do performative actions to appear to care, and voice platitudes of well intentioned progressive goals, even if they are easily shown to only marginally reduce the risk of exposure to raw sewage downstream. It should be noted that except for the 3 locations specified by the 2021 Regional Board Cleanup and Abatement Order, San Francisco has continued with the policy of refusing to address sewage backups, and in fact seem to take some scatalogical pleasure in increasing the sewage disgorged from their sewers into the homes and businesses of San Francisco such as the continued failure to maintain the tide gates and the disastrous closure of the Pierce St. outfall [27].

Friends of Mission Creek joins the Ingleside residents, Marina Residents, Solutions Not Sandbags and others to request the US EPA and Regional Board step in again to address this clear threat to public health and safety. As shown by the 2019 Wheeler letter and the subsequent Regional Board Cleanup and Abatement Order, the combined focus of the US EPA and the State regulators is required to overcome the lethargy and organizational confusion inherent in San Francisco’s approach to sewage backups.

Notes on documents referenced:

The various documents referenced in this letter are from a collection of documents saved by Solutions Not Sandbags, StopFloodingIT, TheMarina94123, Friends of Mission Creek from SFPUC websites (such as the 2010 Sewer System Master Plan documents) as well as numerous public records requests from 2014 to 2024. Solutions Not Sandbags started this collection after sewage flooding onto Cayuga Ave. as well as the Mission District in 2014.

Since late 2024 however, San Francisco has refused to release any documents and have ignored numerous public records requests. For example, see Solutions Not Sandbag’s April 25, 2025 email exchange with Mr. Joel Prather . Friends of Mission Creek offers to the state and federal regulators to assist the various victims of San Francisco sewage backups if additional records can be obtained and shared publicly.

The documents have all been placed on a publicly accessible Google drive in the following folders:

Solutions Not Sandbags WikiLeaks folder
Solutions Not Sandbags folder for Public Records Requests (PRR) Marina Wikileaks Folder
Friends of Mission Creek PRR Folder including requests regarding SFPUC’s failure to maintain the tide gates around Mission Creek and Ingleside Terrace Wikileaks folder
If San Francisco officials would like to provide any corrections, they would be welcome and if any of the above is incorrect, a correction will be issued by Friends of Mission Creek, such as FOMC’s Jan 6th, 2025 correction to Ms. Eileen White of the Regional Board, correcting the statement that the regional board had failed to take any action to address the sewage discharged by the closure of the Pierce St. outfall.

Friends of Mission Creek will continue to work to protect public health and safety including practical, cost-effective ways to improve San Francisco’s combined sewer overflow performance.

Dear Ingleside Terrace Residents,

Thank you for your questions about the Balboa Reservoir project and its potential impact on the Ocean Avenue sewer. The SFPUC has worked diligently with other City agencies and the designers and developers of the project over the course of the last 10 years to require that the project limit its flows to the Ocean Avenue sewer during wet weather events so that the stormwater flow conveyed after project completion is the same as is conveyed before the project is built.

We have pasted your specific questions here with answers below.

1. Will the Balboa Park project include comprehensive upgrades to the Ocean Avenue sewer infrastructure to ensure it can handle increased capacity?
The Balboa Reservoir project does not include upgrades to the Ocean Avenue sewer. However, the project does include requirements for the developer to install large stormwater storage pipes and weirs that will temporarily store and convey the increased stormwater flows from the project. These requirements have been crafted specifically with the capacity in the Ocean Avenue sewer in mind. The SFPUC and other City agencies have stewarded these requirements over the course of project development to ensure that they are delivered. These requirements are documented in the Balboa Reservoir Infrastructure Plan
, dated June 12, 2020:
“Due to existing capacity limitations in the Ocean Avenue combined sewer system, the proposed Project will not increase peak stormwater discharge from the project site during the 5-year, 3-hour and 100-year, 3-hour storm events, including stormwater flow amounts equal to the estimated project peak sanitary flow, as a requirement of the SFPUC for project implementation. Onsite detention and retention will be provided to limit the peak discharge to existing conditions.” (Balboa Reservoir Infrastructure Plan, 2020, p.82)

Functionally, these requirements mean that the project will not increase the peak stormwater discharge to the Ocean Avenue sewer during storm events that occur statistically every 5 years or every 100 years. Furthermore, the project will reduce the peak stormwater flow rate by an amount equal to the project’s proposed peak sanitary sewage flow rate. This offsets an additional worst-case scenario condition in which the project’s peak sanitary sewage flow occurs simultaneously with peak stormwater flow.

2. Will these upgrades be fully in place before or concurrent with construction? The large stormwater storage pipes and weirs under Loquat Lane, Wisteria Lane, and Mayor Edwin M. Lee Avenue will be implemented during infrastructure construction which will either be concurrent or before building construction. The project will also be complying with the San Francisco Stormwater Management Ordinance (SMO), which will result in stormwater management strategies such as permeable pavement and rain gardens to manage site- level stormwater runoff. The stormwater management strategies achieving SMO compliance in the public realm will be delivered during streetscape construction. The stormwater management strategies achieving SMO compliance on the parcels will be built at the time of vertical construction for each parcel.

As climate change contributes to larger and more intense storms, residents and businesses can partner with SFPUC to take steps to protect their properties. We encourage Ingleside residents who have experienced flooding during heavy rains to reach out to SFPUC to see if they are eligible to apply for funding from our Floodwater Grant Program, which offers up to $100,000 per property to increase flood resilience. Our staff are available to conduct site visits, offer technical assistance, and help eligible properties through the grant application process. To learn more about the program we hope you will join our staff for a webinar on Thursday, September 4
th, 5:30pm-6:30pm. They can register for the webinar at sfpuc.gov/floodwatergrant.

In addition to the grant program, the City participates in the National Flood Insurance Program, which provides federally backed flood insurance for homeowners, renters, and businesses. We have information about these programs and more on our website.

If you feel that your neighborhood could benefit from any of these programs and would like to arrange for an in-person informational meeting or session, the SFPUC would be happy to partner with you.

Sincerely,
Sarah Minick

Subject: Yesterday"s 2-min comments for public record
Date: Wednesday, September 10, 2025 8:12:41 AM
Welcome new commissioners and thank you all for your time.

My name is Martin Gothberg and I am a consumer of Tuolumne River water.

I agree with prior comments. I’d like to add that the SFPUC water management planning process is a huge concern. SFPUC is using a Design Drought, an imaginary 8 year drought that has never happened in history. Models tell us it is beyond conservative, unlikely to occur within 8 thousand years or greater. Why should SFPUC be different from water agencies that plan for 6 years? Mashing together two different drought year periods is completely arbitrary and unscientific. We will always be in drought planning mode, facing extreme rationing and cost implications.

The design drought needs to be workshopped and should include time to understand the Tuolumne River Voluntary Agreement as a separate issue. Accounting methods under the current iteration of the TRVA have been shown to be riddled with double counting and is the very definition of using ‘smoke and mirrors’ to further restrict unimpaired flow.

SFPUC claims that we “just don’t know how long a drought can be, especially with climate change” is a problem because:

You can review video from workshops with extensive citations from the Long-Term Vulnerability Assessment (climate change study) which concluded that climate change doesn’t pose additional drought risk and with the earlier runoff it can help SFPUC. SFPUC staff seems to be ignoring the study because it doesn’t support their narrative of needing more money for more storage based on unrealistic demand projections.

Ignoring data and evidence because it is contrary to your narrative means you might have a corrupted decision making process. It is at least a Red Flag. Please look into that.

Please make sure staff has clearly addressed the likelihood of occurrence for the Design Drought and assure they respond to better alternatives as presented.

This behavior of stiff-arming the public needs to change. Thank you again for your time.

Subject: Availability of Addendum to EIR - Ocean Beach Climate Change Adaptation Project Date: Monday, September 15, 2025 9:07:24 AM
Attachments: Notice of Availability - Addendum 1 to OB EIR.pdf The San Francisco Planning Department has prepared an addendum to an environmental impact report (EIR) in connection with this project. The report is available for public review on the Planning Department’s environmental review documents web page (http://www.sfplanning.org/sfceqadocs
). The Notice of Availability is attached.

Since certification of the EIR, the City and County of San Francisco, in coordination with the National Park Service and the California Coastal Commission, is proposing to modify the location of the 2-acre restoration area required by Mitigation Measure M-BI- 2f: Blufftop Foraging Habitat Restoration, because the location identified in the EIR near the northern edge of Fort Funston has already been restored. The proposed 2- acre dune and foraging habitat restoration would be located further south, near the native plant nursery in Fort Funston, mostly within the area evaluated in the EIR for a plant propagation site. The addendum evaluates this project change.
