What value was selected for the 2019 level of carbon sequestration and how was it selected? The carbon sequestration inventory reported a minimum value of 5347 MTCO2e/yr to a maximum value of 1,295,292 MTCO2e/yr. In other words, what value was used to calculate when carbon neutrality is reached.

Evelyn Aug 29 2025 at 11:11AM on page 144

The table in chapter 3 for GHG reduction strategies and measures was in a different format, and listed individual measures. This table for climate adaptation strategies and measures follows a different format, listing the strategy in detail, with just a mention of the # of measures, but not listing measures by name. Should these two tables follow a more consistent format, that may make the information easier to visualize for the reader? These strategies and measures make up much of the document (60 pg of GHG reduction measures, 39 pages of climate adaptation measures), it would be great to more easily locate and search through both sets of strategies/ measures. Links in each table to take you to the start of each strategy, or each measure would be great.

Include partner USDA Natural Resources Conservation Service

Evelyn Aug 29 2025 at 10:34AM on page 113

Possibility to add USDA NRCS as a partner, NRCS provides financial support to farmers/ranchers to upgraded old equipment to new models with lower emissions, or go electric.

Evelyn Aug 29 2025 at 10:31AM on page 114

USDA Natural Resources Conservation Service (NRCS) provides financial support (through USDA Farm Bill programs) to farmers and ranchers to install carbon farming practices, and could be listed as a partner.

Suggest adding a section noting other public agencies that have played a role in this plan (NapaSan, Firewise, busses, etc)

Under AB 1572, it is not the governing jurisdictions that certify compliance every three years. It is all owners of affected commercial, industrial, institutional, and HOA properties with >5,000 square feet of irrigated area that directly certify compliance with the State Water Board.

Patrick Costello Aug 25 2025 at 4:18PM on page 105

To be precise in this section, AB 1572 does not require the elimination of non-functional turf. It prohibits the use of potable water for its irrigation. Therefore, areas with recycled water available may use that to irrigate. Also, non-functional turf zones containing dependent trees will likely also be allowed to continue irrigating with potable water to maintain tree health.

Connect with SMART and AMTRAK, Solano transit.
ZEV express bus, shuttles, on Hwy. 29.

Robert Aug 21 2025 at 5:05PM on page 83

One problem is that Hwy. 29 has unconnected sidewalks and bikeways.

In a keyword search, for example "ZEV", the context is shown in 3-21 with portions of the text on the left side truncated, and so the full text is not visible. Tried 3 different browsers with the same result.

Where is the key for this map? What amount of sea level rise do the different colors refer to?

EW Aug 18 2025 at 1:29PM on page 117

Please look into Green Schoolyards America as a partner to implement this measure on our public school yards.
link
Their goal is to have 30% of the student zone shaded. Based on the CA schoolyard tree canopy equity study map on their website, all but 3 schools in Napa County currently fall below 25%, and 11 fall below 5% shaded in Napa County. Schoolyards have a large amount of open space (= great opportunity to make a difference), and a population eager to learn (=great opportunity to combine actions with education on climate resilience).

EW Aug 14 2025 at 5:59PM on page 168

Would love to see this strategy emphasized at all locations within watershed, and include the impact it will have on other measures/ strategies. When water is channelized and leaves the watershed quickly, there is less infiltration and reduced groundwater, leading to stressed forests, less CO2 sequestration, and higher likelihood of catastrophic fire. The interconnectedness of this with several other measures in the report is not mentioned. Prioritize low-tech, green infrastructure solutions to capture and absorb rainwater, especially in the upper watershed. Start by setting goal that public buildings and schools capture runoff and send it to raingardens/ retention areas on site. Great teaching opportunity for students and public.

EW Aug 14 2025 at 5:49PM on page 73

Within city of Napa, a significant number of cars are on the road to shuttle children to/from school every day. These vehicle miles could be avoided. Evaluate open-enrollment and bus policies?

EW Aug 14 2025 at 5:46PM on page 89

Based on recent comments on various outlets, restriping roads and creating alternative traffic and bike lane alignments (as on 1st St and Brown's Valley Rd) is not well received by the community. A comprehensive plan to develop bike corridors on protected pathways separated from traffic is needed. Hiding bicyclists behind parked cars creates poor visibility for both bicyclists and drivers. A few E-W bicycle corridors would be beneficial to get residents from neighborhoods into central part of city of Napa, and onto vine trail. Other countries are way ahead of us in bicycle use by people of all ages, and integrate pathways into city planning. Do we also need to consider the different impact of e-bikes vs. conventional cyclists? e-bikes travel fast, and are much heavier in the event of an accident, should they be in the same bike lanes with other cyclists?

EW Aug 14 2025 at 5:37PM on page 57

Why not include strategy to plant trees on SW side of schools and public buildings? Shade on buildings in the afternoon when cooling demand is highest reduces reliance on other energy sources for cooling. Though there is inclusion of topic urban forestry in measure AG-5, this is a simple and impactful method that you can relate to energy efficiency of existing buildings. Schools especially have significant amounts of open space around the buildings (ie. space for trees), hot blacktop, and kids/ teachers/ parents who would appreciate shade.

Miguel García Aug 14 2025 at 2:52PM on page 14

Does the estimate for the agricultural sector only represent emissions associated with farm equipment or does it also include carbon cycling in the soil?

L Aug 13 2025 at 12:39PM on page 22

I love the list and the bolded text here

Celeste Mirassou Aug 12 2025 at 7:41AM on page 16

Looking forward to an explanation of the change in goal to be climate neutral by 2030 to 2045 especially considering climate emergencies declared by each municipality.

Please elaborate on the “extensive” outreach:

What about emissiions from wildfires? Are they accounted for elsewhere?

Can't find the appendices. Would like to download the document as a pdf as well.

Recently, I sent Trump Administration an e-mail about Global Warming/Climate Change coming train wreck/disaster/abyss if we do not alter course off of coal burning, etc, and move to clean, green, renewable energy sources that do not add to or pump more massive amounts of carbon dioxide(a greenhouse gas) into this planet's atmosphere, than what we humans have already done. I laid out all the information for them with links to information, organizations, and people. It is not easy to think at this level of thought. I am trying to save our world/planet here. There is also link website on the internet about sea level rise in a cartoon or kid friendly format. I saw that on the NASA channel (Ch. 32) on AT&T U-verse cable TV. Even in cartoon format, I found the information relevant and easy to understand. -Matt Zax, Napa, CA
