National Park Service Trees Meet Chainsaws in Montara

The National Park Service is cutting down trees in Montara, south of San Francisco. San Francisco Forest Alliance opposes this action. We’re disappointed. In this era of global warming, every tree counts. Instead of destroying trees, they should be planting them. Instead, they appear to have succumbed to the same “native” vs “non-native” xenophobic approach to plants that we’re battling in the Bay Area.

Here we go again. This time it’s the National Park Service destroying trees in the Bay Area. They just cut down perfectly healthy Monterey cypress and pines – some 100 years old — at Rancho Corral de Tierra, which is located at the tip of Half Moon Bay. If you’ve ever hiked or ridden a horse or bike at Rancho you know there are few trees that provide shady resting spots along popular trails.

These trail-side trees are isolated and one in particular, on the Farallone trail, has been an iconic stop, where hikers take a break to enjoy scenery, grab a drink of water, and shoot the breeze. It’s been a favorite among residents of Montara, many of whom walk outdoors just steps from home as part of their daily routine. No more. Park Service chainsaw crews leveled the tree last week.

By the end of next week the Park Service will be on track to kill 40 trees because they categorize them as non-native. It doesn’t seem to matter that their birthplace is only 100 miles down the road in Monterey. Apparently that’s not local enough.


The Park Service gave no warning and did not engage the community for input at Rancho. They are so strident in carrying out a preferred landscape ideology that a handful of favorite trees could not remain.

Rancho is the newest land added to the 80,000-acre Golden Gate National Recreation Area. The Park Service acquired it in 2011. You may remember that just one month after taking over as land manager a Park Service ranger used her taser gun to shoot a 50-year-old man in the back after he gave a false name. The ranger had stopped him for walking one of his two small terriers off-leash. He won a $50,000 judgment against the Park Service for unreasonable use of force.

Now the Park Service is now using unreasonable force against trees under the guise of biodiversity. They claim it will save a rare flower, Hickman’s potentilla, against an invading force  even though the trees have remained far apart for years, showing no sign of taking over the landscape.

The fact that the flower has peacefully co-existed with the trees for decades doesn’t matter to the Park Service. The project is part of a multi-million dollar grasslands restoration and replanting program bankrolled by the Golden Gate National Parks Conservancy.

The Park Service did not conduct an environmental assessment to justify the dramatic changes being made to the landscape and it’s refusing to disclose how much glyphosate is being sprayed.  Glyphosate, better known by the Monsanto trade name Roundup, has been declared a probable human carcinogen. California, which in July declared glyphosate to be a carcinogen, is considering requiring cancer warnings on Roundup brand labels.

The community is shocked and angry. You should be too. California lost 100 million trees due to the recent four-year drought. We can’t afford to be killing trees. Yet that’s exactly what the Park Service is doing at Rancho Corral de Tierra.


Here’s a statement from GGNRA received today:

“NPS is pausing tree removal work at Rancho and is planning to offer an additional public hike in the coming weeks to discuss our planning process and the overall recovery plan for the Rancho grasslands and Hickman’s potentilla. We plan to send out an announcement to our Rancho mailing list once this date is set.”

This is a pause – not a promise to stop the cutting. We will stay in touch with you all as we move through this process to keep our voices heard.

Please enjoy the moment – your voices and help from Congresswoman Jackie Speier’s office were very important to get this temporary pause – thank you!


SF Forest Alliance: Problems in the Sutro Forest DEIR – Part II

On September 22, 2017,  the Aqua Terra Aeris Law Group, on behalf of its client, San Francisco Forest Alliance, submitted the following comments and questions to the University of California, San Francisco (“UCSF”) regarding the Draft Environmental Impact Report (“DEIR”) for the UCSF Mount Sutro Open Space Reserve Vegetation Management Plan (“Plan”).

D. The DEIR Fails to Adequately Assess or Mitigate Erosion Impacts.

The DEIR fails to include meaningful analysis or mitigation measures for erosion controls. Again, to some extent, this deficiency flows from the fact that neither existing conditions nor the exact scope of the project is defined. Nevertheless, numerous members of the public have submitted comments based on scientific review and personal experience highlighting that widespread tree removal in the forest will expose soils and degrade soil integrity in an area with steep slopes and high moisture accumulation. Many of these effects may not be immediately evident—for example, only years after a tree is removed may the root structure left behind totally rot—yet the DEIR describes and attempts to mitigate only impacts short-term impact such as access road construction and landing area. (DEIR 2-22 to 2-24.) Thus, the DEIR fails to completely analyze the project’s significant adverse impacts, and fails to support its conclusions with substantial evidence.

E. The DEIR Fails to Adequately Assess Greenhouse Gas Emissions.

The DEIR fails to disclose fundamental information for an accurate greenhouse gas (“GHG”) emissions analysis. The DEIR acknowledges that tree removal will cause GHG emissions, but fails to meaningfully analyze the numbers and types of trees to be removed and replaced. For example, the summary on page 3-27 does not sum up how many trees will actually be removed. Table 3.5-2, column 6 provides the net reduction or increase in trees, but this does not indicate how many living trees will be removed. That is because the numbers presented are net removals, i.e., living trees removed, plus dead trees removed, minus new trees planted.

The DEIR’s treatment of old trees as equivalent to new saplings is also incorrect. Based on best current scientific information, large, old trees do not act simply as aging carbon reservoirs but rather continuously fix large amounts of carbon compared to smaller trees. (N.L. Stephenson et al., Rate of Tree Carbon Accumulation Increases Continuously with Tree Size (2014) 507 Nature 90.) This study determined that the oldest trees gained the most mass each year and subsequently, accumulating more carbon, capitalizing on their additional leaves. (Id. at 91-92.) The DEIR fails to account for this information when it claims that “[y]oung, healthy forests absorb carbon more rapidly than older, dense forests (Wayburn 2010).” (DEIR at 4.6-18.)

It is also false to assume that carbon sequestration in a forest ceases at a certain point. The DEIR presumes “the Reserve’s mature eucalyptus are well past peak growth, and are no longer sequestering much if any additional carbon.” (DEIR at 4.6-19.) Per the Stephenson paper, supra, and Peter Ehrlich’s updated forest assessment of eucalyptus trees in San Francisco post-drought described below, this is incorrect, insufficient, and inadequate. Additionally, these assumptions result in an inadequate baseline. Given the end of the drought, a significant number of trees deeming “dying” by the DEIR have likely recovered their canopies and are sequestering more carbon than in April 2016. Conversely and without evidence, the DEIR assumes 100% survival rates for new saplings planted, incorrectly ignoring the mortality rate for these new trees, especially given the lack of irrigation. When removing mature trees, the U.S. Forest Service recommends a 3:1 replanting ratio to account for the loss of carbon sequestration and expected sapling death.

The DEIR also lacks calculations regarding the projected biomass and CO2 of the replacement trees in future years. To fully understand the impacts of the Plan, information about carbon sequestration at incremental years, such as 2020, 2030 and 2050, would more fully disclose the Plan’s impacts. Executive Order S-3-05 and Executive Order B-30-15, have targets that need to be reached by 2020, 2030 and 2050, but without presenting GHG impacts at these critical years, the public cannot know whether the Plan will conflict with applicable plans, policies, or regulations as required by CEQA. (Guidelines, § 15064.4, subd. (b)(3) [“A lead agency should consider . . . [t]he extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gas emissions.”].)

The DEIR is lacking information on other critical GHG measurements. The DEIR does not provide estimates for changes in soil carbon, though the changes to the surface throughout the Reserve will disturb the soil. (DEIR at 4.6-15.) This is especially true because the plan for understory removal is to dig out the understory plants by the roots. Additionally, the DEIR fails to provide estimates have for carbon contained in the woody shrubs and understory that will be extensively removed and destroyed. (Id.)

Finally, the DEIR fails to account for the Plan’s cumulative impacts on climate change, stating that “a single project is very unlikely to measurably contribute to a noticeable incremental change in the global average temperature, or to the global, local, or microclimate.” (DEIR at 4.7-16.) When making this determination, however, an EIR may not conclude that a cumulative impact is insignificant solely because the project’s contribution to an unacceptable existing environmental condition is relatively small.  “[T]he impact of greenhouse gas emissions on climate change is precisely the kind of cumulative impacts analysis” that agencies must conduct. (Center for Biological Diversity v. Nat’l Highway Traffic Safety Admin (2008) .) One project may not appear to have a significant effect on climate change, but the combined impacts of many sources can damage California’s climate as a whole.

Therefore, CEQA requires that an agency consider both direct and indirect impacts of a project and fully disclose those impacts to adequately inform the public and decisionmakers. (Guidelines, § 15064.) The DEIR, because “[c]arbon sequestration in the forest would exceed GHG emissions generated from equipment and loss of carbon stock/uptake from tree removal,” concludes the Plan’s impacts will be less than cumulatively considerable. (DEIR at 4.7-17.) This failure to consider the Plan’s impacts in conjunction with other plans and projects flouts CEQA’s mandate.

Ultimately, the DEIR’s Greenhouse Gas analysis is deficient. UCSF’s conclusion that the Plan will not have a significant impact on the environment is unsupported without a full disclosure and analysis of the Plan’s greenhouse gas impacts. CEQA “requires full environmental disclosure.” (Communities for a Better Environment, supra, 184 Cal.App.4th at 88; see also Guidelines, § 15121, subd. (a).) Although “technical perfection” is not required, an EIR must be “adequa[te], complete[], and a good-faith effort at full disclosure.” Because the DEIR fails to include and consider recent scientific information, fully describe the Plan, analyze compliance with relevant regulations and policies, account for significant sources of carbon, and analyze cumulative impacts, it fails as an informational document and does not present an accurate picture of the Plan’s impacts to the public or decisionmakers. UCSF must correct these areas and recirculate the EIR.

F. The DEIR Fails to Adequately Assess and Mitigate Wind and Local Climate Effects.
Commenters have pointed out that Sutro Forest was originally created in part to help calm winds from the Pacific Ocean into the City. The effect has considerable influence on the microclimate of the immediate vicinity, as well as nearby areas, such as Noe Valley, Dolores Heights, Castro, Bernal Heights, or the Mission, allowing more fog and wind to pass through the forest into nearby areas. Commenters have noted that Sutro Forest has the highest moisture content of any location in the City, and massive vegetation removal may logically have the effect of changing this moisture collecting condition and changing weather patterns in the City. San Francisco is well-known for its micro-climates, and this project effect cannot be simply ignored. Without collection and evaluation of micro-climate data in the City, the DEIR fails to assess this project effect.  A revised and recirculated DEIR should include detailed observation about the microclimate and forest conditions.

G. The DEIR Fails to Adequately Assess and Mitigate Impacts to Biological Resources.

First, the DEIR fails to provide a meaningful assessment of impacts to avian species and their habitat. Principally, the removal of thousands of standing dying trees deprives protected bird species of next, perch, and boring spaces. (See: Eucalyptus tree hosts a flicker family)

A loss of understory also impairs habitat and foraging opportunity. (See: Mount Sutro Forest Ecosystem and Wildlife Habitat)  These project effects must be analyzed.

Second, the DEIR fails to adequately mitigate impacts to Monarch Butterflies. BIO-PH-1 is inadequate because it enables UCSF still to cut down the trees on which the monarchs were found after the butterflies have left. This is destroying essential monarch butterfly habitat and the exact trees that the butterflies are likely to try to return to the following year. Aggregation on trees themselves are hard to spot. Monarch butterflies are often seen flying around San Francisco’s eucalyptus forests, but where are their home trees? How will the biologist determine whether the aggregation has dispersed or not, and what is the time frame? This is unclear in the DEIR. A 200-foot buffer is inadequate for species protection given the significant disturbance that the Plan’s deforestation will create around the aggregation trees including heavy equipment, the construction of landing areas, and clear cuts of 1 acre or more.

The DEIR concedes that “Implementation of forest treatments including eucalyptus removal could cause a significant impact on monarch butterfly by removing trees that monarch butterfly may use as roosts during winter months” and “Impacts would remain significant.” (DEIR 4.3-22) Given recent studies’ finding the species to be severely imperiled throughout the West, the lead agency may be unable to justify a statement of overriding considerations to approve this project, and the No Project Alternative should be selected, and/or the project denied.

Commenters have noted that Eucalyptus oils act as natural deterrents to pests such as mosquitos and fleas, while the area is known as a frequent destination for dog walkers. The DEIR should assess project effects to reduce this natural defense. In addition, because the Eucalyptus blooms in winter, it is an off-season food source for bees, which have also suffered alarming population declines. The DEIR should investigate and analyze this effect.
Again, the DEIR fails to completely analyze the project’s significant adverse impacts, and fails to support its conclusions with substantial evidence.

E. Conclusion

For each of the foregoing reasons, we urge that the project be denied, that the No Project Alternative be adopted, or that the DEIR be substantially revised and recirculated for public and agency review and comment.

SF Forest Alliance: Problems in the Sutro Forest DEIR – Part I

On September 22, 2017,  the Aqua Terra Aeris Law Group, on behalf of its client, San Francisco Forest Alliance, submitted the following comments and questions to the University of California, San Francisco (“UCSF”) regarding the Draft Environmental Impact Report (“DEIR”) for the UCSF Mount Sutro Open Space Reserve Vegetation Management Plan (“Plan”).

Members of the public have commented with deep and justified concerns that the possible benefits of this project are unclear or unlikely, while the effects are significant. What is now a peaceful, historical refuge from City life threatens to become a multi-decadal vegetation removal project that would drastically alter the biological landscape of the forest, its quietness, degrade its air quality, increase greenhouse gas emissions, construction traffic and congested city parking . . . the list goes on. Yet the basic purpose and actual scope of the proposed project are not clearly conveyed, and are not compelling at all. The forest has survived countless drought cycles on its own, without this type of intrusive intervention. As a result, the lead agency may be unable to support a statement of overriding considerations to approve the project. The proposed project should be denied, and the No Project Alternative accepted.

Sutro Forest

A. CEQA Overview

An EIR is an “informational document” meant to “provide public agencies and the public in general with detailed information about the effect which a proposed project is likely to have on the environment” and “demonstrate to an apprehensive citizenry that the agency has, in fact, analyzed and considered” the environmental impacts of a project. As an informational document, CEQA “requires full environmental disclosure.”  Although “technical perfection” is not required, an EIR must be “adequa[te], complete[], and a good-faith effort at full disclosure,” with “informed and balanced” decisionmaking. (CEQA Guidelines, § 15003, subds. (i)-(j).) “[A]n agency must use its best effects to find out and disclose all that it reasonably can.”

For each of the reasons discussed, below, the DEIR falls short of CEQA’s informational and substantive requirements, and should be revised and recirculated. In the alternative, the proposed project should be denied, as the No Project Alternative would meet the project goals while reducing or avoiding significant and unavoidable effects of the proposed project.

B. The DEIR Conflates the Proposed Project with its Attempt to Describe Existing Conditions – and so Fails to Provide Either a Legally-Sufficient Project Description or Baseline.

An accurate project description and a baseline are two legally crucial elements of the CEQA process. Furthermore, an agency can accurately describe a project’s impacts only if it accurately describes the existing environmental baseline, measuring the project’s impacts against “real conditions on the ground.”

1. The DEIR’s Stated Project Objectives are Unclear and Inadequate.

A proposed project’s statement of objectives must include the underlying purpose of the project, and be clearly written to guide the selection of mitigation measures and alternatives to be evaluated in the EIR.

Alternatives that cannot achieve the project’s underlying purpose need not be considered; “a lead agency may not give a project’s purpose an artificially narrow definition, a lead agency may structure its EIR alternatives analysis around a reasonable definition of underlying purpose and need not study alternatives that cannot achieve that basic goal.”

The DEIR summarizes the four plan objectives as follows:

1. Protect the safety of Reserve users and adjacent campus and residential properties
2. Improve and enhance the health and stability of the ecosystem
3. Enhance the visual design and aesthetic experience in the Reserve
4. Maintain and ensure public access to the Reserve

(DEIR at 1-2 [pg. 20].) Regarding the first objective, the DEIR explains that aim is to reduce “the risk of tree failure and fire through vegetation management.” (DEIR at 3-13 [pg. 77].)

However, the DEIR fails to provide meaningful information by which to understand these goals. For example, are existing forest conditions unsafe? By what measure? Similarly, are public access limitations currently a problem? The DEIR is not specific, and fails to consider whether years of significant “vegetative management” in the Forest would impede public access more so than not pursuing this project at all. Only through better-articulated project goals can the DEIR and the public meaningfully assess whether alternatives to the project would also meet project goals with fewer significant environmental impacts.

The DEIR also acknowledges that UCSF is already doing work to mitigate these risks – and will continue to do so whether or not the project is approved. The DEIR states that under the proposed project, “UCSF would continue to manage the risk of trees that may fall and injure Reserve users or damage property, and vegetation management would be focused in areas where people and buildings may be affected.” (DEIR at 2-12 [pg. 36], emphasis added.) The DEIR adds that the forest is already “actively managed” for safety. (DEIR at 4.5-1.) And crucially, it explains that:

If the proposed plan is not approved by the Regents, it is reasonable to assume that UCSF would continue to conduct ongoing maintenance in the Reserve to reduce fire hazards and hazards to people and structures from falling trees. Ongoing maintenance would include, but would not necessarily be limited to, pruning trees and bushes, removing hazardous trees, removing debris, and maintaining trails.

(DEIR at 2-14 [pg. 38]; see also DEIR 5-6 [pg 406] (under the No Project alternative, UCSF would “continue to conduct ongoing maintenance in the Reserve”).) So how can the first and foremost objective of the proposed project be to reduce “the risk of tree failure and fire through vegetation management” if the DEIR asserts that such management will happen whether or not the plan is approved? In light of the fact that the proposed project would result in significant and unavoidable impacts, and since the No Project Alternative satisfies the first and foremost objective of the proposed project, the No Project Alternative should be selected.

Unfortunately, the DEIR barely describes this pre-existing / active management program.  At one point, the DEIR describes safety assessment of trees up to 25 feet on either side of trails (DEIR 3-18 [pg. 82]), but does not describe to what extent trees have been removed based on the assessments. In those few places where the pre-existing program is described, it tends to mirror the proposed project precisely. For example, under the proposed plan, vegetation would be trimmed “within 5 to 10 feet of trails” to “allow trail users to see further into the forest.” (DEIR at 4.1-23.) But the DEIR indicates that UCSF already trims “vegetation within 5 to 10 feet on either side of trails to maintain sight lines through the forest.” (DEIR at 4.6-11.) As a result, because the DEIR barely describes the existing program of active forest management, it has failed to establish an adequate baseline.  And because core elements of the proposed project (the vegetation and tree management plan) will continue under this existing program of forest management, whether or not the proposed project approved by the Regents, the DEIR has also failed to establish an accurate project description.

2. The DEIR Fails to Provide an Accurate Stable Description of the Number of Trees Existing or to be Removed.

The DEIR’s description of the baseline conditions that are integral to the proposed project activities are inaccurate and unstable, giving rise to an inaccurate and unstable project description. A description of important environmental resources that will be adversely affected by the project is critical to a legally adequate discussion of the environmental setting. And specific information about particular characteristics of the environmental setting are be required when necessary to determine the significance of an impact.

First, a huge discrepancy exists between estimated tree numbers from previous years and the current estimates. In 2013, UCSF “estimated that there are approximately 45,000 or more trees in the Reserve.” (UCSF Mount Sutro Management DEIR (Jan. 2013) at 3-5.) The DEIR estimates there are approximately 12, 135 trees in the Reserve. (DEIR at 3-9, tbl. 3.4-1.) The DEIR fails to realistically account for this vast difference in its own calculations, whether consultants’ prior calculations were wildly inaccurate, or there were an inordinate number of trees between 1 and 2 DBH at that time. The DEIR gives short shrift to these implausible explanations, and the discrepancy casts significant doubt on the accuracy of the DEIR’s estimations and the public’s ability to rely on its description.

Second, the DEIR proposes to remove “approximately 6,000 trees predominately dead and/or dying trees” during Phase I. (DEIR at 3-24.) Yet the DEIR fails to even estimate how many “dying” trees exist in the Plan area. Unsurprisingly, the DEIR lacks a clear definition of the words “dead” and “dying” when describing trees. It merely characterizes trees with a live crown ratio of 25% or less as “dying” without recognizing that crown die-back is a normal adaptation to drought for eucalypts and many of the trees have a good chance of recovery.

The Live Crown Ratio is the ratio of the crown to the total height of the tree, simply a measure of how high the crown is. For similar reasons, this measure is of questionable value with considering eucalyptus which goes through cycles of extension and dieback. This is especially true when the eucalyptus is growing in a forest environment, where a long trunk and high crown is the natural growth habit of Tasmanian blue gum. A Live Crown Ratio of 33% would be standard, and so 25% seems well within the normal range of variability, especially during a drought. (See, “Forest
Trees of Australia” by Douglas Boland, Maurice William McDonald.)

The DEIR presents two varying estimates of the number of live trees in Forest Type 4. In Table 3.4-1, it estimates there are 50 live trees per acre and 50 dead trees per acre in Forest Type 4, for a total of 100 trees per acre. (Id. at 3-9, tbl. 3.4-1.) But in Table 3.5-2, it estimates there are 128 live trees per acre and a total of 178 trees per acre in Forest Type 4. (Id. at 3-27, tbl. 3.5-2.) The Vegetation Management Plan published in February 2017 provides the 128 live trees per acre figure. (Vegetation Management Plan (Feb. 2017) at 24, tbl. 6.) This is a significant difference. Table 3.4-1 lists 8,665 live trees in total for the entire forest. If applying the 128 live trees per acre number for Forest Type 4, the total number of live trees increases to 10,069. This is an increase of 16% and is significant with respect to the ecosystem value of the forest and impacts from removal. Given that the number of live trees impacts all of the analyses and conclusions, these discrepancies render the DEIR insufficient as an informational document.

Additionally, the “Net Trees Removed or Planted per Acre” thresholds in Table 3.5-3 are significantly higher than needed to achieve the Desired Final Stand Density in Forest Types 1, 3 and 4. If UCSF implements these maximum thresholds, then only 243 original trees would remain by Year 10. Examining Appendix 4.2 shows that at least 12,101 trees (99.8% of the current total) would be removed by Year 11 alone. This near-complete-deforestation is internally contradictory with the Plan’s stated objective to improve the health and stability of the Mt. Sutro open space reserve.

The DEIR proposes to remove over half of the live trees on the Reserve in the first year of the Plan, estimating that there are 8,665 trees in the Reserve (DEIR at 3-9, tbl. 3.4-1), but proposing to cut down a maximum of 4,640 lives trees (DEIR at 3-27, tbls. 3.5-2 & 3.5-3)—a staggering 53.5% of the live trees at the Reserve. This is a significantly high percentage and poses threats to public safety and wildlife, yet the DEIR concludes the impacts will be less than significant with mitigation. The DEIR must be amended to accurately depict the impact of its forest clearing plan.

The DEIR also fails to provide an accurate baseline description of existing tree health, relying on drought year data that ignores the extent to which the wet 2016/2017 winter may have revived trees on Mt. Sutro. According to the U.S. Forest Service, “During times of defoliation, crown dieback may be overestimated. This can be due to the difficulty of distinguishing dead twigs from defoliated ones.” On December 4, 2016, the Chief Forester of the Presidio, Peter Ehrlich, described the eucalyptus forests in San Francisco as follows: “The trees are recovering from a three-year drought. Those trees that were of moderate vigor showed recovering canopies that no longer had evidence of epicormic growth that was produced in a drought-response. This crown retrenchment was a survival strategy for some of the trees in order to cut water loss during drought. The trees are recovering due to the increased rainfall last year and early this year.” Even the DEIR admits that “the drought conditions have ended in 2017” and “future conditions are unknown.” (DEIR 3-11.) Since this is a forest with over 100 years of adaptation through numerous drought cycles, it should be permitted to recover prior to making any new and drastic vegetation management decisions. Eucalyptus in the tropical and arid areas of Northern Australia tend to get killed by termites and fire before they’re 200 years old. In temperate, rainy Southern Australia they live 400-500 years. San Francisco’s Sutro Forest is much closer to Southern Australia in climate, since it lacks wildfires and cyclones and receives rain as well as summer fog drip.

Accordingly, both the existing conditions and the project need and scope are fatally undermined without relying on more accurate data.

Finally, the DEIR wrongly claims that vegetation in the forest is “even-aged.” (DEIR at 4.1-25.) But any visitor to the forest can see—and even the photos in the DEIR show—a wide range of tree sizes and ages. (See, e.g., id. at 4.1-4, 4.1.5, 4.1-12 to 4.1-21.) This occurs in part because eucalyptus globulus can regenerate readily from lignotubers, younger trees will sprout from trees that are cut down or broken off. Over the 125-year life of the forest, it is evident that many of the trees now standing are younger.

These errors, inconsistencies, and failures to disclose important facts result in an inaccurate and confusing Plan description and baseline by which to compare the Plan’s impacts. As a result, the DEIR fails as an informational document the public and decisionmakers can rely on.

C. The No Project Alternative Should be Selected, but the DEIR Skews Decision-making by Failing to Adequately Assess the No Project Alternative.

The CEQA Guidelines require that:

The specific alternative of “no project” shall also be evaluated along with its impact. . . The “no project” analysis shall discuss the existing conditions at the time the notice of preparation is published, as well as what would be reasonably expected to occur in the foreseeable future if the project were not approved, based on current plans and consistent with available infrastructure and community services.

The No Project alternative is distinct from the environmental baseline, from which the impacts of a project are evaluated.  The no-project alternative is a fact-based forecast of the environmental effects of maintaining the status quo.  When a project involves a proposed change to an existing land use plan, regulatory plan, policy, or ongoing operation, a decision to reject the project would leave the existing plan, policy, or operation in place. In such a situation, the no-project alternative should be defined as a continuation of the existing plan, policy, or operation. The EIR’s discussion of the no-project alternative then compares the impacts of the change that would result from approval of the proposed project with the impacts that would occur if the existing plan, policy, or operation remained unchanged.

The Sutro Forest DEIR addresses a No Project alternative in which the proposed plan would not be implemented, but UCSF would “continue to conduct ongoing maintenance in the Reserve.” (DEIR 5-6 [pg 406].) As a result, the DEIR expects that eucalyptus would thin and “either understory vegetation or blackwood acacia [would] colonize areas of eucalyptus dieback.” (DEIR 5-7 [pg 407].)

There are serious problems with the DEIR’s treatment of this alternative. Although it presents a No Project alternative, the DEIR describes that alternative in conclusory and pejorative terms, with little explanation.

1. With Nearly No Explanation, the DEIR Concludes That the No Project Alternative Would Lead to Significant Impacts on Visual Quality.

California courts have struck down EIRs that reject project alternatives on aesthetic grounds without providing sufficient explanation of why one alternative is visually less desirable than another. (See Save Round Valley Alliance v. County of Inyo (Ct. App. 4th 2007) 70 Cal. Rptr. 3d 59 (“If the BLM parcel is indeed an unsuitable site for the project due to whatever the County referred to as ‘aesthetic/view issues,’ much more must be said to adequately inform the public and decision makers.”))

Here, the DEIR describes the No Project alternative’s hypothetical transition from eucalyptus to understory vegetation or blackwood acacia as having significant “impacts on visual quality.” (DEIR 5-6 [pg 406].) But the DEIR does not explain anywhere why it views eucalyptus as of higher visual quality than acacia blackwood. (Neither species represents an indigenous California visual landscape; both species are transplants from Australia.1) Are eucalyptus prettier than acacia? The DEIR does not say.

In contrast, some Bay Area residents extol the visual appeal of blackwood acacia. For example, one local science writer and environmental consultant wrote that:

“I first noticed [Blackwood acacia] for its flamboyant seeds. When the pealike seed pods split open later in the year, they will reveal a shiny black seed surrounded by a wild curlicue of orange ribbon. I hate to love an invasive, but I think they are just beautiful.”

Others describe the tree as “beautiful and dependable,” possessing seeds “wrapped in an unmistakable coral-colored ribbon.” It may be the case that eucalyptus is prettier than the blackwood acacia. But it is certainly not self-evident, and the DEIR provides no justification for this conclusion.

The DEIR is also inconsistent about whether gaps in the forest canopy are appealing or not.
When it is describing the proposed project, the DEIR says that “gaps in the canopy that create patterns of sun and shade and offer views of the ocean and Golden Gate Park” are visually appealing. (DEIR at 2-2 [pg. 26].) But when it is talking about the No Project alternative, the DEIR says that “as the canopy becomes patchier” the “visual quality of the Reserve would decline.” (DEIR at 5-6 [pg 406].) It sounds the DEIR has a heads-I-win-tails-you-lose approach to aesthetics – openings in the canopy represent appealing gaps when the DEIR is describing the proposed project, but unappealing patches when it is describing an alternative.

Finally, and bizarrely, the aesthetic analysis of the DEIR’s describes the forest resulting from a No Project alternative as potentially “less alive.” (DEIR 5-6 [pg 406].) (It does not explain what it means by this.) But elsewhere the DEIR admits that “[a]lthough the dominant species in the forest may change, the Reserve would likely continue to be forest land under the No Project Alternative.” (DEIR 5-7 [pg 407].)

2. With Nearly No Explanation, the DEIR Pejoratively Characterizes a Transition from Eucalyptus to Acacia as “Forest Decline”.

Similarly, in terms of Biological Resources, the DEIR pejoratively characterizes “understory vegetation or blackwood acacia” colonizing potential areas of eucalyptus dieback under a No Project alternative as “forest decline.” (DEIR 5-7 [pg 407].)

The DEIR does not explain why a transition from mostly one species to mostly another species constitutes “decline,” but it may be based on a misreading of another section of the DEIR. In Section 3, the DEIR points out that the “condition of the blue gum eucalyptus trees has declined over the past decade” and that “[w]ithout management, it is likely that the existing eucalyptus will continue to decline and die, and other types of trees and vegetation will take over.” (DEIR 3-6 [pg 70].)

Thus, the DEIR appears to have conflated the decline of one species in the forest – eucalyptus – with the health of the overall forest. (More generally, the DEIR repeatedly employs language like this to create the image of a forest that is aged, ill, dying, and infirm. The aim may be to create the idea that the forest is not worthy of the land itself.)

In fact, California arborists praise the blackwood acacia’s role in a forest, calling it “a good choice where a large, fast-growing tree is desired.”5 Elsewhere it is described as a “durable tree for quick growth, screening and erosion control.”6 The acacia’s seed pod is “rich in protein, which makes the seed package rather appealing to ants, which consume the aril and discard the seed, in a fertile rubbish heap, or in the nest.”7

It is particularly misleading for the DEIR to describe the No Project alternative as “forest decline,” because that term is often understood to refer to the removal of trees. It is the DEIR’s proposed project – not the No Project alternative – that involves cutting down lots of Mount Sutro’s trees. (DEIR at 219, 4.1-26, etc.) As a result, if the DEIR wishes to characterize the transition from eucalyptus to acacia as “decline,” it will have to show its work. (See City of Arcadia v. State Board:  “a public agency must explain the reasons for its actions to afford the public and other agencies a meaningful opportunity to participate in the environmental review process.”) As noted, above, a Eucalyptus forest can be expected to live up to 400-500 years without human disturbances such as the proposed project.

3. Without Meaningful Explanation, the DEIR Concludes that Leaving the Forest Alone Would Have Greater Impacts Than Cutting Down Many of Its Trees.

The DEIR concludes that “the No Project Alternative would result in greater environmental impacts than the proposed plan.” (DEIR 5-10 [pg 410].) While this could be true, it is certainly counterintuitive that cutting down many or most of a forest’s trees would have less of an impact than leaving the forest alone.

The only explanation that the DEIR provides for this conclusion is to point to the seven categories in which it assesses the No Project alternative’s impacts to be higher than the proposed project – “aesthetics, biological resources, cultural resources, landslides and topsoil loss, fire hazards, emergency access, and windthrow.” (DEIR 5-10 [pg 410].)

But the DEIR acknowledges that the impacts from a No Project alternative would be comparable or less than the impacts from the proposed project in eight categories – air quality, forestry resources, greenhouse gas emissions, hazardous materials, hydrology and water quality, noise, recreation, transportation and traffic. (DEIR at 5-6 to 5-10.)

For that reason, CEQA requires more explanation regarding the DEIR’s counterintuitive conclusion that the No Project alternative would have greater environmental impacts than the proposed project. (See Guidelines: “The EIR shall include sufficient information about each alternative to allow meaningful evaluation, analysis, and comparison with the proposed project.”)

Tree at 826 Haight May Be Saved

In a little bit of good news, we recently received this letter from a supporters, telling of a possibly successful attempt to save a street tree on Haight Street, San Francisco CA. It’s published with permission.

Hi Folks,

Another partial win for a critical component of our urban forest — street trees, in this case a lone blackwood acacia at 826 Haight Street facing removal. The other day DPW [Department of Public Works] head Muhammed Nuru reversed a request to remove the tree after a Public Hearing was held for neighbors protesting its imminent removal.  The tree removal order was overturned, delayed for 90 days while BUF reassesses every means of saving this healthy, mature tree including construction of a larger basin and sidewalk repair that slopes to accommodate the tree roots and base.

See below for a copy of the decision #186300.  The decision urges BUF [Bureau of Urban Forestry] to consider all means to keep the tree in place and report back in 90 days.

The Bureau of Urban Forestry is starting to take notice of our objections to the summary removal of mature street trees after being schooled in the multiple benefits of a large urban forest canopy from the perspective of climate change, carbon sequestration, respiratory health, wildlife habitat, drainage, heating/cooling and mental health.   BUF has seen the necessity of taking a deeper dive into their usual standard operating procedure of posting a removal notice without seeing a stewardship role prioritizing street trees, especially after our opposition and intervention with Guy Place Park, 75 Howard Street and this lone acacia tree.

[We wrote something about that HERE: Killing our Street Trees in San Francisco ]

We organized 20 written protests, a petition with 117 signatures and 5 neighbors giving oral testimony.  The organizing tool was Next Door.

Hopefully, this signals a small beginning and recognition by BUF and RPD of the need to preserve and expand each component in our dwindling urban forest canopy volume. And perhaps this can influence the City’s new responsibilities under Prop E and the minimalist approach both City Planning and MTA takes with area plans and streetscape improvement projects occurring throughout the City.

DPW ORDER #186300:

“The Director of Public Works held a Public Hearing on Monday, July 24, 2017 at City Hall to consider Order No. 186127 for the removal with replacement of one (1) street tree adjacent to the property at 826 Haight Street.

Findings: Urban Forestry staff testified that the tree was initially posted for removal due to its age, species, structure, and sidewalk condition. Blackwood acacia, Acacia melanoxylon, does not tolerate root pruning well, once the root’s of a mature blackwood acacia are significantly pruned they tend to rot quickly. The accelerated root rot can often lead to full tree failures. Currently, the sidewalk is in poor condition, and must be repaired. The main branch union has poor structure, and all of the co-dominant scaffolding branches originate from the same location on the trunk, which can lead to large stem failures. Urban Forestry staff stated that if the tree were to remain, the sidewalk repair would have to be carefully completed without cutting any roots. The tree basin would also have to be expanded to at least 6’x12′. The canopy should be thinned & large scaffold branches with the worst structure should be removed or the weight reduced.

“The Bureau of Urban Forestry received approximately 20 removal protests from the public in writing, and five (5) members of the public spoke at the hearing against tree removal. A petition was also created which received 117 supporters against tree removal. After the tree hearing Urban Forestry staff surveyed the underground utilities near the tree. It was found that high voltage electric lines run directly beneath the tree basin, and if removed, the tree will not be able to be replaced.

Recommendation: After consideration of letters and testimonies presented at the hearing the decision is to reverse the Bureau of Urban Forestry’s approval of tree removal with the following conditions: the sidewalk repair will consist of a basin expansion only and no roots shall be cut. Any additional concrete uplift will be shaved/sliced, not replaced. The tree canopy shall be pruned and significantly thinned within three (3) months to reduce the potential for large stem failures. If the Bureau of Urban Forestry concludes that the sidewalk repair cannot be made without pruning the roots, the tree removal will be approved and a courtesy notice and report documenting the efforts to retain the tree, will be provided to those who attended the hearing and/or submitted correspondence. The courtesy notices would also be placed on the trunk of the tree and nearby utility poles.”

So it’s not over yet, but we’re very encouraged that a good faith effort is being made to save this tree. Thanks, Matthew and everyone who worked on this.


Here’s the Sutro Forest DEIR (issued July 2017)

For those readers who would like to get started on reading the Draft Environmental Impact Report for  Mount Sutro Open Space Reserve, we have it here as a PDF:


Sutro Forest DEIR Announced

UCSF has released a humongous 1087-page Draft Environmental Impact Report on the Plan to cut down thousands of trees in Sutro Forest. The deadline for public comment has been extended in response to our request, to Sept 22, 2017. This two-week extension from Sept 8th is a lot less than the 60 days we asked for, but it’s better than nothing.

Here’s an excerpt from UCSF’s letter:

“In response to your request, UCSF is extending the public comment period for the Draft Environmental Impact Report (DEIR) for the proposed UCSF Mount Sutro Open Space Reserve Vegetation Management Plan.  The comment period will be extended by two weeks for total of 60 days: public comments on the DEIR are now due on Friday, September 22.  All comments must be received by 5:00 p.m. on Friday, September 22, 2017.  CEQA guidelines have established that the public review period for a DEIR should not be longer than 60 days (Section 15105).

“Send written comments to the attention of Ms. Diane Wong, UCSF Campus Planning, Box 0286, San Francisco, CA 94143 or email to

It’s interesting that they invoke the 60-day maximum under CEQA guidelines, but ignore the guideline that says the DEIR text should be 150 pages or at a maximum, 300 pages….


UCSF will hold a public meeting on August 24, 2017

“There will be a public hearing to receive oral comments on the DEIR on August 24 at 6:30 p.m. at Millberry Union, 500 Parnassus Avenue, on UCSF’s Parnassus campus.

Killing Our Street Trees in San Francisco

The tree which moves some to tears of joy is in the eyes of others only a green thing that stands in the way.”
William Blake, The Letters, 1799

Most of these Jefferson Street trees were saved due to neighbors’ efforts! Fisherman’s Wharf, San Francisco

San Francisco has a lot of projects going on. SFMTA seems to be flush with wealth, and is “improving” a lot of roads. Developers are planning fancy new buildings.

Unfortunately, every project seems to start with destroying trees – and neighbors never know about it until it’s a done deal and the trees have 30-days-to-death notices on them. Then they object… but the odds are against them. Though they sometimes succeed in saving the trees, more often it’s too late.  Meanwhile, the City seems to be entirely accepting of tree destruction for any and all reasons.

San Francisco has a tree canopy of only 13.7%, the lowest of any major city, and nearly half the appropriate canopy cover of 25%.

(From SF Data: In preparation for the San Francisco Urban Forest Plan (2013), the Planning Department performed an Urban Tree Canopy (UTC) Analysis using aerial imagery and additional data sets to determine a canopy estimate for the City & County of San Francisco. This analysis estimated San Francisco’s tree canopy at 13.7%)

San Francisco Has the Least Canopy Cover of any Major US City

This is an embarrassment for a “green” city, quite aside from the ecological, environmental and health reasons for saving our trees. Unfortunately, between Nativists, developers, and project managers, there seems to be a wave of tree cutting hitting San Francisco. We’re not augmenting our canopy, we’re shrinking it.


  1. Trees fight pollution, especially particulate pollution that is dangerous to human lungs.
  2. Trees improve air quality
  3. Trees are good for physical and psychological health; to get the same benefit as living on a tree-lined street, you would have to be ten years younger.
  4. Trees provide habitat for wildlife, especially birds and butterflies.
  5. Trees help regulate water by absorbing it into their roots and gradually releasing it through their leaves.
  6. Trees reduce crime and improve business.

Two years ago, neighbors fought to save this lovely grove of trees at Geary and Masonic. They were cut down because of plans that merely considered them as “green things that are in the way” and were not designed to preserve them.

These trees are now gone. Here’s what that grove looks like now:


This charming line of street trees, fighting pollution and climate change, and breathing out oxygen in downtown San Francisco, is also gone. In its place there will be a tower block with a footprint out to the sidewalk.

Where once there were trees.


Plum trees the neighbors loved were removed at Fort Mason, leaving the neighbors in shock.

The tree destruction continues, but in some cases at least it may be possible for neighbors to prevail.

The Rincon Point Neighbors are fighting to save ten trees at Howard and Steuart streets. The hearing is May 31 at 5 pm in room 416, City Hall.  Comments should be submitted on the Thursday prior to the Hearing, May 25th, 2017 (Today!) according to Board of Appeals rules. You can email them at:

Neighbors are seeking to save this tree, one of the few large shade and habitat trees remaining on Haight Street. It’s disrupting the sidewalk, but an arborist has determined that the tree can be saved simply by enlarging the tree basin to accommodate its roots, fixing the sidewalk, and pruning some of the branches.

If you want to help save this tree, you can sign the petition here, and also email the Bureau of Urban Forestry  at and tell them you protest the removal of the tree at 826 Haight. — deadline June 21, 2017)
