  • Comments for the Natural Resources Commission review of DiSC 2022

    TrafficThe following comments were shared with the Natural Resources Commission at its meeting last night and are reposted here with permission of the author.

    This is Alan Pryor speaking as a former 12-year NRC Commissioner. I think it's telling to review a comment made by a Planning Commissioner at a hearing on this project last year.

    "You want this to be the most sustainable, innovative tech campus in the United States. But you have come to us with a car-dominated, auto-centric proposal on the edge of town, far from the capitol corridor station, not linked to good transit, with huge parking lots and parking structures. Widening Mace to accommodate more traffic is not the answer. It's going to induce more traffic."

    Nothing has functionally changed with this project since then except its size is been reduced by less than half but the applicant is now proposing transportation features that are even less conducive to non- automotive forms of transportation.

    For instance the applicant is now refusing to construct the previously agreed upon off-grade crossing to allow arriving pedestrians and bicyclists to safely cross six lanes of Mace Boulevard during rush-hour traffic. How is that possibly welcoming to bicyclists and pedestrian employees arriving on the west side of the street or to school kids living at the project trying to get to school and back each day without a parent driving them.

    Also, the original proposal was an environmental nightmare in that it projected over 83,000,000 lbs of CO2 equivalent emitted each year. The new estimate is about  45,000,000 lbs of CO2 equivalent per year – or about 4.5% of the City's current carbon footprint for this one project alone. All of these emissions would have to be later eliminated for the City to reach carbon neutrality by 2040 but the developer has not proposed how they will do this.

  • Use of American Rescue Plan Funds (ARP) to obtain an Urban Tree Canopy Assessment and Report

    Street-treesThe following letter was shared with the Davisite this morning.

    Dear City of Davis ARP Subcommittee:

    The City of Davis' urban forest is comprised of trees, gardens, green spaces and other natural areas. This urban tree canopy provides a myriad of benefits making our communities cleaner, safer and healthier while reducing the costs associated with many services. Managing, monitoring, and enhancing this important resource is critical to sustained economic development and environmental health.

    I am requesting that sufficient ARP funds are dedicated to allow for: (1) A complete analysis of Land Cover and Urban Tree Canopy; (2) Assess an Ecosystem Benefits Analyses, including: air quality, energy, stormwater, and carbon; (3) GIS-based and other tools to model strategic tree canopy development scenarios; and (4) Complete training for Davis Tree Canopy Partners, such as Tree Davis and the Tree Commission, on use of these tools to accomplish management objectives.

    Urban Tree Canopy Assessment and Report (UTCAR) would be a onetime use of ARP Funds and benefits all living animals and humans regardless of gender and group stereotypes, including race, age, ethnicity, ability level, socioeconomic status, or sexual orientation. An UTCAR would bring data from various studies to evaluate and understand the extent and value of the region’s trees and to provide a benchmark of the urban tree population, land cover, and the value of the current and potential future urban forest.

    The data and tools produced will enable planners, managers, and commissioners to develop strategies for community development, air quality enhancement, energy conservation, stormwater management, and community forest management.

    The UTCAR would be conducted in a manner that defines and quantifies various environmental and economic benefits of the region’s tree canopy, known as ecosystem services, focusing on air quality, energy use, stormwater, and carbon sequestration.

    The dynamic modeling tools developed for this project would allow planners and managers to envision and plan their desired future urban forest. With these tools, users identify and prioritize strategic tree planting areas based on management objectives, and create alternative designs and cost/benefit scenarios at a regional-scale or for specific sites.

    Though the City of Davis' urban forest is relatively young, it nonetheless provides substantial benefits that can be quantified, monetized, forecasted and enhanced over time with proper planning and management. To maximize the function and value of the urban forest resource, it is critical to target canopy increases strategically and to educate policymakers and citizens about the benefits of urban tree canopy.

    Thank you for your consideration.

    Sincerely,

    Tracy DeWit

  • Leeward Renewable Energy, Valley Clean Energy Sign 15-year Solar-Plus-Storage Power Purchase Agreement for Willow Springs 3 Solar Facility

    Project to provide 72MW of solar power, 36MW of battery storage for Valley Clean Energy customers

    (From press release) Leeward Renewable Energy (Leeward) and Valley Clean Energy (VCE) announced today that they have entered into a 15-year solar-plus-storage Power Purchase Agreement (PPA) involving Leeward’s 72-megawatt (MW) solar and 36 MW (144 megawatt-hour) battery storage Willow Springs 3 facility in Kern County, California.

  • Letter to the Tree Commission re: DiSC 2022

    Red leaves

    One of Davis's urban trees

    To Davis Tree Commission:

    In regard to the DISC proposal (Item 6B on your agenda this evening),  I support your subcommittee's recommendations and encourage you to recommend them as a "baseline feature".

    Given that the size of the proposal is already known, recommendation of a specific number of trees should be achievable (as it was during the previous iteration of the proposal).

    I understand that the developer is proposing to satisfy shade requirements via the use of solar panels or trees. Unfortunately, this type of "choice" will increasingly be used by developers, as we've already seen in regard to Sutter Hospital's expansion. It may be that developers generally prefer solar panels, to help them meet other requirements (and to claim that a given proposal is "green", while simultaneously eliminating "greenery" in regard to trees).

    At some point, the city itself will need to come up with a clear policy regarding the use of solar panels vs. trees for given situations. While either can be used in parking lots, trees (unlike solar panels) require soil and space to survive. As such, solar panels are suitable for a wider variety of locations (such as rooftops), while trees are not.

    Until/unless the city comes up with a clear policy (supported by the tree commission), I would encourage the tree commission to not be distracted by an "either/or" choice, and simply focus its efforts on recommendations regarding trees and the benefits they provide.

    Sincerely,

    Ron Oertel

  • Comments to the Tree Commission concerning DiSC 2022

    Screen Shot 2021-10-19 at 9.55.57 AMThe following was emailed to members of the Tree Commission this morning.  The Tree Commission is scheduled to discuss the revised MRIC/ARC/DISC project, now dubbed DiSC 2022, at its meeting this Thursday, Oct 21.  If you wish to comment on the project yourself, see instructions on the agenda for the meeting, located here.

    Dear members of the Tree Commission,

    I am writing to you as a former commissioner (10+ years) and Chair of the Open Space and Habitat Commission (OSHC), having completed my term last December. I was involved in analyzing what is now being called the DiSC 2022 project in all of its iterations, so I hope you find my comments helpful in your discussions.

    I think it's great that you appointed a subcommittee to review all the materials, given that the changes are more extensive than the City has stated – this is not just a project that has been cut in half, as your subcommittee's analysis shows. I endorse your subcommittee's recommendations and encourage you to adopt them as a body in the strongest possible language, remembering that the only way to guarantee that a promised feature will be in the actual project is for it to be designated as a "baseline feature." A cautious route would have you even recommend that the relevant ordinances be satisfied (this was something that the OSHC did last time), since there is a history of the City Council bending its ordinances, including ordinances concerning trees (it is my belief that they did this in the recent Sutter parking lot decision).

  • Yocha Dehe Joins The Sierra Club, Yolo County Farm Bureau, And Residents, To Demand Sensible Cannabis Land Use Policy

    Tribe joins suit calling for changes to flawed Cannabis Land Use Ordinance

    (From press release) In an effort to hold Yolo County accountable for developing fair and sound cannabis land use policy, the Yocha Dehe Wintun Nation has partnered with the Sierra Club, Yolo County Farm Bureau, and local residents in a lawsuit to do precisely that.

    The lawsuit does not seek to stop cannabis cultivation and related businesses in Yolo County, or to prevent County residents from profiting from the cannabis industry.  Rather, it would simply require the County to comply with California environmental law by evaluating the full and real impacts of cannabis cultivation, and mitigate those impacts, before adopting an ordinance regulating it.  Adhering to this process is what the California Environmental Quality Act requires, and indeed, these same requirements apply to every other regulated land use.

    “The cannabis industry has a place in Yolo County, just as cannabis has a place in the medicine cabinets of many people in California,” noted the Tribal Council of the Yocha Dehe Wintun Nation. “But sensible cannabis permitting can’t happen until the County is clear-eyed about the problems overconcentration creates, especially in sensitive areas around schools, near cultural heritage sites, and in smaller communities like those in the Capay Valley.”

  • Report from the Open Space & Habitat meeting re: DiSC 2022

    Screen Shot 2021-10-03 at 8.45.43 PM
    The following was originally posted as a comment in response to the Davisite article Comments to the Open Space & Habitat Commission concerning DiSC 2022 and has been reposted here as an article with permission of the author.

    By Ron O

    In regard to the Open Space and Habitat Commission meeting last [Monday] night, here are some highlights:

    The recommendation (from the article linked above) to request that the northern (approximately) 100 acres be established as agricultural mitigation was not discussed or considered by the commission. Two commenters reiterated this request. (The 100 acres was part of prior proposals.)

    The commissioners proceeded to review and edit the recommendations made when the proposal included the northern portion of the site. The developer representative claimed that many of them no longer applied, since the northern site is not part of the current iteration. As a result, the commissioners edited and deleted large sections of the prior recommendations, on-the-spot.

    As the meeting approached 9:00 p.m., the chair suggested that a second meeting be held, given the amount of work left to be done. However, several commission members were not able to attend an additional meeting prior to the October 18th deadline set by the council. The chairperson stated that the council put the commission in a "bad place", and stated that she was "very unhappy" about it. The chair stated that they had received the packet for review on the previous Friday afternoon (for this Monday meeting).

  • Comments to the Open Space & Habitat Commission concerning DiSC 2022

    Screen Shot 2021-10-03 at 8.45.43 PM
    The following was emailed to members of the Open Space and Habitat Commission (OSHC) on Sunday.  The OSHC is scheduled to discuss the revised MRIC/ARC/DISC project, now dubbed DiSC 2022, at its Monday Oct 4 meeting.  If you wish to comment on the project yourself, see instructions on the agenda for the meeting, located here.

    Dear members of the Open Space and Habitat Commission,

    I am writing to you as a former commissioner (10+ years) and Chair of the OSHC, having completed my term last December. I was involved in analyzing what is now being called the DiSC 2022 project in all of iterations, so I hope you find my comments helpful in your discussions.

    To begin, I am pleased to see in the minutes from your last meeting the following: "[Ms. Reynolds] said the Commission also had the option of agendizing the Addendum to the project's Environmental Impact Report ("EIR") later this year if the Commission wanted to provide comments on the Addendum to the EIR. That meeting would have to happen before December when the project is scheduled to go before the Planning Commission, she said." I strongly urge you to do this. The OSHC has a history of productively discussing and giving comments on EIRs, as it did with earlier versions of DISC as well as Nishi and other projects, with the comments thoughtfully crafted from the Commission carrying more weight than comments from individual members. For example, you might wish to ensure that the biological surveys have been properly updated and that greater awareness of approaches to climate change are being taken into account, such as the lost opportunity for regenerative agriculture on the property if the project is built.

    Another important piece of background: in the last iteration of the project, the developer kept insisting that Mace 25 was not part of project, even though it clearly was. This led to mistrust in the community. Because of that mistrust, people are now concerned that this smaller project without Mace 25 is just a foot in the door for the already rejected larger project to come later. I urge you to recommend that the developer state, as a sign of good faith, that this is not their intention — designating the ~100 acres to the north of the project as ag mitigation would be the clearest way to do that.

    The rest of my remarks will focus on the Staff Report and related attachments, located online here.

  • Particle Wars in Davis –  What you can’t see can kill you, Part II…

    Screenshot from 2021-08-19 17-42-32

    The militarization of gardening?

    A conversation about the proposed – and not – restrictions on toxic micro-particle hyper-distribution -  a.k.a. “leafblowing” – by three of your favorite local activists!

    (COVID is Part I)

    This evening the City of Davis Natural Resources Commission (NRC) will hold the first of two hearings on possibilities for leaf blowing restrictions. Here’s the memorandum – a supplement to Council’s approval of temporary leaf blowing restrictions from last October. It includes Commission and Staff proposals and results of the surveys on leaf blowing taken which were taken in June.

    In summary, they are proposing a gas LB ban, time restrictions and user restrictions. Staff and Commission (sub-committee) proposals are broadly similar. 

    What’s very important, however, is that there is a strong likelihood that there will be a complete ban at the state level on gas-powered equipment such as lawn mowers, edgers and so on… including leaf blowers and vacuums, or combined units. This means that any equipment-related ban in Davis that only affects gas blowers will be nothing unique in just a couple of years. 

    The meeting is at 6:30pm

     

    AirNow08062021

    Leaf blowing prohibited on this day?…

    AIR QUALITY and wildfire fallout:

    Todd Edelman: There is no explanation of why the air quality-based restriction due to wildfire fallout  is based only on official AQI according to current City policy. For example, the very popular and relatively inexpensive Purple Air system could be used.  And Purple Air isn’t only used at private residences: The UC Davis environmental engineering dept has one on its roof for experiments. Lake County Air Quality Management District (AQMD) uses them for official monitoring outside of wildfire situations. The New Jersey Transit Authority seems to also use them for official purposes. Sutter Davis Hospital has them on their roof and inside. The elementary school at Beale Air Force Base has one, as does the Yolo Solano AQMD office in south Davis – they say they use it to recognize “trends”.

    But perhaps the most important use of Purple Air is to determine local impacts of leaf blowing…

    Previewonleafblowerstoryno2

    Nope… no new restrictions if the air's bad AFTER 7:30am…

    Darell Dickey: I have trouble with the concept that we can only ruin our air quality when the air is otherwise pretty good. We’re going to avoid dirtying the air when it is already bad? And then there’s my favorite part: Blowing will always create a local situation of AQI over 100, which should result in an immediate ban on blowing. 

    I’m thinking that a good, logical way to present this is that if we’ve all agreed that 100 AQI is “bad enough” for us to ban activities that make it worse, then we should never be allowing the use of devices that make the AQI 100+. And this circles back to local air quality vs. relying entirely on one spot of data that’s outside of town to determine what we’re breathing in our neighborhoods at any given moment. 

    If AQI 100+ is bad anywhere, then stop creating AQI 100+!

    TE: There is nothing about how they determine how much ash is on the ground, though this is a condition of the lift of any AQI-based restriction according to current City policy. I have voiced this concern many times.

    There were several times when the official AQI went over 100 during the day but not before 9AM; this was not mentioned in the memorandum, though I brought it up repeatedly in August in emails to the NRC.

    LEAF-BLOWING, WILDFIRE SMOKE AND COVID-19

    The proclamation from October 2020 that resulted in temporary leaf-blower restrictions mentions “COVID-19” 10 times, yet the current memorandum only mentions it once, and not directly in relation to smoke effects on those with who have COVID. Further, the October 2020 mentions no specific research at that time on wildfire smoke and COVID, but there’s new research not mentioned in the memorandum. 

    AIR QUALITY, general:

    TE: As far as I can tell leaf vacuums distribute lots of dust, and as they pick up inorganic matter as mentioned in the memorandum, I don't see how they will be allowed. But still, do people think that these things work as HEPA interior vacuums?

    DD: True. But “lots of dust” from a vacuum situation is still way better than any blowing. It all needs to be in perspective as we’ll never arrive at “perfect.” Same way that electric cars aren’t perfect, but are better than gas cars, etc.

    TE: Well, I think at least all the most dangerous and invisible stuff comes out the back…

    DD: “Most dangerous” is not easy to defend. If the crap being stirred up produces a violent health reaction (allergies, asthma, etc), then the acute “most dangerous” thing is probably coming out the front. At least for those people who are severely affected.

    The only way to call any of this “better” is if less crap is being put into the air…. As compared to doing it another way. And IMO, a vacuum is better than a blower. And leaving stuff where it is, is better than all of it.  The timing of the device usage is also important. I vacuum up deep leaves to mulch them and put them where they’ll help the yard vs. choke the plants. And I do it when the leaves are not dusty. It is a relatively benign activity.

    LABOR:

    TE: There's no suggestions related to the labor issue except for what may eventually be affected by a ban on gas-powered blowers. What are their wages, by the way? This is a basic question for labor related actions or studies.

    DD: I hate the question where they ask the company how much it will financially destroy them. Of course the answers are all opinion, but it is presented and answered as fact. 

    TE: Yes they should give figures or something. Is there possible funding from AQMD to transition out of all leaf blowing?

    DD: Also, a significant percentage of landscaping businesses do not use any blowers. 

    TE: Why is this? How is this influenced by opinions of consumers and of workers or their managers/companies?

    DD: From what I can tell, the biggest concern from the citizenry is that they may have to pay more to the poor, under-paid folks. You know… the folks that they’re really concerned about harming with…. low wages.

    Asking the yard-care business owners how bad it will be if blower use is restricted is like asking El Macero drivers how bad it will be if Mace loses one of its travel lanes. It is a total guess. It is based on everything else not changing. And they simply have no idea what the result would be. Might be higher health and better hourly wages for everybody. But of course most claim that it will just be devastating to their business. I didn’t hear one response about how it would be better for the workers who might get paid more for doing healthier work.

    TE: I’ve repeatedly brought up this part of the issue, not only with the NRC, but also the Social Services Commission — it needs to agree to provide feedback. Though leaf-blowing is not a job based on sustainable practices, there are many related jobs which are, and they require a higher skill-set. Tree trimming, building on-site composting facilities, triage of soil situations? No one should lose their jobs. 

     

    LABOR AND PHASE-IN:

    TE; There seems to be no scientific reasons for only phasing out gas blowers in City properties except for protecting some companies. Nothing about increasing wages, etc. The proposed start date Jan 1 (2023) is after most of the "leaf season", and over two years since the temporary regulations came into effect. This seems to be about giving enough time to buy new equipment, but this seems like a tiny expense compared to labor.

    Purple Nation

    VIBRATION (Sound):

    Roberta Millstein: You two are rightly focused on the air quality. But for a broader audience, you might also mention that these things are f*cking loud. Really f*cking loud. And that is for some a big part of why they are hated.

    TE: I know that traffic noise is very bad for human health. One thing that’s worse about leaf blowing noise is that it can be unpredictable, especially if one’s neighbor is doing it — but then also who memorizes the leaf blowing schedules of their neighbors or their yard sterilization services?

    While most electric leaf blowers are quieter than gas-powered ones, it’s not guaranteed. And if an electric leaf blower is less powerful than a gas one, people may use it for longer.

     

    OTHER:

    DD: And the main reason that some give for the “need” of leaf blowers? No other practical way of clearing large paved parking lots. 

    TE: Exactly, what are uses of LB's in terms of square footage or acres, etc?

     

    CULTURE: 

    TE: Yard work is good exercise if the air is clean. It connects one to their yards – even in a rental property – that other exercise outside cannot.

    Leaf blowers and vacuums didn't exist in significant numbers until what, the 1980's? What did people do before that? Die, in their yards, under piles of leaves?

     

    EFFECT ON TREE AND SOIL HEALTH:

    TE: In the Memorandum there's nothing from the Commission or Staff in the recommendations about the benefits of leaving leaves where they fall, even though it’s already recommended on sources linked from the City's Tree pages and others.

    The Tree Commission will hopefully offer feedback.

     

    EXAMPLES / Best Practice in Other Places:

    TE: There is mention of the other jurisdictions which have done partial to full bans, but not by name. They clearly have this list. There is no indication how many suffer significant wildfire fallout, though as many are in California certainly some have, and there's an assumption about why most didn't respond. Two have complete bans… who are they?

     

    EFFECT ON OTHER USERS OF ROW (street, greenbelt, or another public space):

    TE: There's nothing about how use of blowers contributes to the always non-permitted piles of yard waste in bike lanes. At the October meeting of BTSSC we need to pressure them into agreeing to providing an opinion on this, especially as a related item on yard waste in bike lanes has been sitting in the long-range calendar for many months as TBD. This issue has been going on for many years.

    Proposed ban during the week is only til 8AM, even though many are commuting to school or work by then, by pedal or foot. So then they will be exposed full-on as they traverse the City.
