is Everd Buzzy, I'm a researcher and a product marker at the Census and then we go for being here. I'm Mali Anderson and I'm a writer at the Census. So over the last several months, we've been trying to figure out ways to measure and define the decentralization of the Ethereum network. Generally, the most popular comparative metric for the import of the false is throughput. Most of us know that the more decentralized and secure blockchain is, the lower the throughput, at least at this stage in the tech's evolution. So transactions per second are not a very effective measurement. So what do we actually talk about when we talk about decentralization? How can we objectively measure its extent and to monitor its evolution over time? Obviously decentralization isn't a binary, is or isn't a condition, but a very complex and emergent process that will change the network growth. What data can we measure objectively? Originally, we set out to define a quotient or some standard measurement that can replace throughput as a comparative data point. But we quickly realized that we get into Apple's oranges pretty fast when we try to compare most of these metrics across protocols. So we never focus a bit to say, what can we objectively measure Ethereum right now and watch chamber for time? What's actually happening on main net and what does it tell us about the progress that we're making or not making? So here are the questions we set out to answer. Is Ethereum actually getting more decentralized over time? Are there metrics to the network getting more centralized? Does the data reveal areas we need to focus on addressing or changing? Given some of the trends we're observing, can we make any meaningful predictions about the future and which of these metrics can be compared across protocols? So our approach to measuring Ethereum decentralization over time began with determining which elements of Ethereum's architecture, both on and off chain, most significantly impact base decentralization. So to start off with at this age, the research identified 19 key subsystems spread across four different categories to investigate. We attempted to anchor our conclusions in as much on chain and objective data as possible, which can get tricky. And it's also important to note that there are data points that we have not covered that we wish we could. We consider them important, but not necessarily on chain and they can be very difficult to quantify. Those include concepts like the strength and distribution of power grids on which nodes run and illegal jurisdictions and the relative stability of countries on which large numbers of nodes are hosted. So for as many of these data points as possible, we track their evolution quarter over quarter as far back as possible. Essentially from the earliest days of Ethereum, through gradual adoption, rampant speculation, hacks, crypto-kitties, the bubble, and sort of the subsequent course correction that we've seen in the past year or so. So we measured and charted about 20 or so different metrics. Obviously we don't have time to run through all those today. So we chose a few of them spread across these different categories that we're going to talk about for a bit. So looking at account growth, we looked at, started off looking at total account growth over time compared to active account growth over time. So on the x-axis is quarter over quarter across the past four years for beyond most of the charts that we've seen. And then the blue line is total address growth over time and the red line is active addresses, which we define as addresses out of transactive response. And that spike in Q2 is the Shanghai tech during the Debcon 2. So we see a compromise increasing steadily over time, but we see active addresses more or less starting to flatten after the bubble. So as it was achieved to note, but this is the growing delta between the two lines over time, which likely is due to the increase in smart contract activity on the network rather than just simple PDP value transfers. Here's another account growth graph. This one shows account growth over time by total addresses in gray versus addresses with a non-zero ink balance and orange. So what we see is a fairly steady linear increase in non-zero addresses on the network with no major bumps, even during the dramatic price fluctuations. We can't necessarily say this means there's been a steady increase in the number of individuals we need because the addresses are subdominous. But what we should consider again is the growing delta between the new addresses and the new non-zero addresses that is getting steadily wider as more smart contracts emerge since smart contract addresses have no leaf balance. We're seeing a pretty clear increase in both non-zero addresses and smart contract addresses over time. The evolution could indicate that the network is supporting more diverse and thus more decentralized types of business logic executed on Anet. This following graph illustrates e-thownership of the top 10 100 and 1000 addresses compared to total supply over time. So the bottom and red are the top 10 and then yellow are top 11 to 100 and then top 101 to 1000 and then all the way up to 100%. So the story that this tells is fairly obvious. We see the top 10 and 100 addresses on the Ethereum network on any steadily lower percentage of the total heap holding that could just be likely due to the passive result of increasing supply over time. We do see some of these larger accounts possibly being pushed down into lower tiers of ownership while others move up in their place which also could account for the recent uptick we see in the percentage of Ethereum by the top 1000 addresses in the past few quarters. When we're looking at the trend of ownership, general trend of ownership since 2015, we see that e-thownership is becoming more diverse across addresses. We can't assume that more new addresses means more new unique individuals participating in the network. However, we can see that the number of non-zero addresses are increasing and the concentration of the top 10 and 100 are decreasing alongside each other over time. This could possibly suggest that contrary to the popular narrative, the crypto bubble was not overwhelmingly followed by whales and holders buying back crypto at those lows just to make a buck off of what would be the eventual market uptick. Rather, this negative correlation could suggest that more and more new people began accumulating at a steady rate after the bubble which alongside growing each circulation could have been reducing the percentage of concentration of these top 10 and 100 whale holders. So the ecosystem being as young as it is, the unequal concentration of wealth isn't necessarily a major red fire for decentralization in the long term even with the still large concentration of wealth on the fine whales. Ethereum is still pretty far ahead compared to other blockchain protocols at least on this metric. Looking ahead, however, ETH concentration in the hands of a few becomes more of a concern when we shift to group of state and influence on the network becomes more closely correlated with ETH ownership. As the beacon chain gets more functional and as POS replaces proof of work, it'll be important to watch out for the staking power concentrating in the hands of a few. So this graph shows the total circulating volume of ETH compared to the circulating volume of select ERC-20 tokens which are shown as token value in ETH. So this green line shows the total amount of circulating ETH, i.e. ETH moving between addresses quarter to quarter. It's essentially correlated with the price of ETH with the spike in circulating ETH aligning with the price high in late 2017 and early 2018. And then the bar chart shows the value of a select few ERC-20 tokens circulating quarter to quarter. We looked at the top 10 by market cap, plus a few interesting ones we wanted to look at like die, zero x, medic, and loom. The purpose of this graph is to see effective ETH network is getting more diverse from both utility and the speculation perspective. What we think it shows is that despite a relatively stagnant ETH price recently, the ETH value in circulating tokens is increasing dramatically. And not only is the circulating value increasing with the diversity and market share of tokens are increasing too, suggesting that users are using more ERC-20 tokens and doing more with them across the board. These two graphs, one on the top one on the bottom, shows the growing concentration of mining pools over time as measured by a percentage of total block production on the top and then a percentage of the total miners are being paid out on the bottom. And then in each of these graphs, each color corresponds to the same mining pool. So for instance, the green that's on the bottom of each graph is ETH mine and then so on to the rest. So over time, we see that four pools have really started to dominate the mining pool landscape. Those are ETH mine, F2 pool, Spark pool, and Nano pool. Collectively, they've edged out past previous competitors like Mine and Pool Hub and Dwarf pool, which are, you can't even see the percentage isn't there, barely see their importance in the past few quarters. So those four pools, those four major pools now account for over 72% of quarterly block production, again, the top graph, and they pay out to about 83% of the miners across mining pools, again, that's the bottom graph. So in particular, we're seeing a particularly concerning, possibly concerning dominance in block production between ETH mine and Spark pool, which today account for just under 50% of blocks produced per quarter. And together, we're seeing ETH mine and Nano pool pay out to nearly 70% of the miners on chain. So the concentration of the influence among a few mining pools is definitely not ideal, but it's not necessarily a major concern by itself. Miners are pool agnostic, they will migrate to whatever pool offers the best incentives. And if we assume rational behavior by miners, if a single pool were to reach a hatch rate close to 50%, or start physically colluding with other pools to amount to 51% attack, it's not outside of our own possibility to presume that miners would abandon those pools to protect their income and switch to other pools. However, when we look at the number of mining pools and miners over time as shown by this graph with mining pools in the orange and miners in red, we see a distinct decline in both over the past year. In short, what this means is that we have fewer miners that are active on fewer mining pools and fewer mining pools being responsible for network maintenance. As a quick note, it's important to say that the number of miners in red is not entirely accurate. We base the number of miners in mining pools based off of the on chain payout addresses, but some mining pools pay out their miners off chain just through more traditional bank deposits. These numbers will be a bit off, but we can't tell those off chain numbers. So overall mining pools could be an area of increasing centralization on Ethereum. We have lower ETH prices, reduced block rewards, and a fairly stagnant hatch rate that could be the reason for miners not joining the mining pools recently, and then also we just have a loss of efficiency concentrating the power of mining pools in fewer and fewer mining pools. So with NIE towards the future, the eventual switch to proof of stake will redefine this metric of centralization, but until then it's fairly prudent that we keep an eye on how it's concentration of mining pools and miners and the relative power evolve over time. So next one, we'll look at no diversity. So this data is from No Tracker on Etherstand, and it shows a no count by country starting in 2018, which is unfortunately only as far back as the data goes. It's a heat map, so the warm colors are the highest no counts and the cooler colors are the lower no counts. And in general, we definitely see some unfortunately bare areas that stay pretty consistent over time, such as the African continent, but we do see pretty uniform fluctuations rather than random sudden spikes in different geographical areas that are unequal from other countries. And it's also helpful to see that the network is physically quite distributed and decentralized across the globe and across a variety of legal and political systems. So these two graphs look at the node size versus the price of the leaf. There's been a lot of fluctuation in the total countable nodes running the Ethereum network. Right now, for example, I think the number is about half of what it was around this time last year. So on the surface, that looks a lot like centralization. There are fewer nodes overall, and presumably fewer people running nodes. There are a lot of reasons why that could be, but these graphs show two factors we looked at to see if there's a correlation. So on the left, we're comparing the number of active nodes to the average heat price for the recorder. Actually, I think this is week over week. So maybe when the price is high, it's a common belief that more people think it's worth it to run nodes. That doesn't actually seem to be the case, over the course of 2019, which is, again, all the data we were able to get. When we look at the node count in the same graph in blue as the heat price in green, it looks like there's actually a new correlation, that a node count was one of its lowest points in June, one of the prices the highest, and the count was quite high during the price tip at the end of the summer. So even if this correlation might have been true historically, and that's why people think it exists, it doesn't seem to be true right now. So then on the right, we checked the node count against the total size of the default node on death, which is the red line, and in parity, which is the orange line. About 97% of all the nodes on the network are running one of those two clients, and about 95% of the nodes on the network are default nodes, and opposed to archived nodes, which were, of course, a much higher date for them. Obviously, the average node size is more or less the same phase number of times, as a box or mind. It seems reasonable to assume that as the default node size gets bigger, it gets more expensive and takes more energy to keep the node running and keep it synced, so maybe sure people are doing so. And that looks like it's the case when you look at the graph on the right, or at least we see a clearer relationship than there is with the price of these. As we move toward KOS and charting the network, the node size burden will have to be as much of an issue, so maybe this attrition won't continue on the same trend into next year. There are also some interesting experiments happening around the ecosystem to find ways to make running a node easier and cheaper, so we wanna keep tracking this one through the changes that the next year is gonna bring on the network. So we set out to start measuring potentialization. We, of course, envision this fabulous graph or tracker that would compare pretty consistent decentralization metrics across protocols that very quickly, as Madis said in the beginning, sort of devolved into comparing apples and oranges. And we, of course, recognize that based off different consensus algorithms, you can't compare the same metrics across protocols. And so we took that original 19 subsystems that we showed, we said, okay, which ones could be possibly and confidently compare across at least a few protocols? And, you know, for instance, a proof of authority, or sort of, to have a VOA blockchain which is very different than it would for approved work, or for state blockchain. And so the next step would be to sort of take this adjusted series of subsystems and see if we can confidently compare them across, across chains. The difficulty is, of course, act as some data for those chains. So what conclusions can we take away from all this? First, we think the network is most clearly decentralizing when it comes to the reduction in the holding power of the top 10 and 100 addresses. As we head toward Ethereum 2.0 and group of state watching what happens with these ownership percentages will be crucial. Second, we think that the clearest area of centralization is in the mining pools and the concentration of power between handful of pools. We also suspect that no nutrition is a big one, but we just don't have enough historical data to predict what we're going to do later. As a third conclusion, we're not, as a larger point, we're not necessarily trying to make a decision about if the ecosystem is doing a good or bad job of decentralizing Ethereum or even making any value judgment. It's obvious that the activity on Ethereum is getting more diverse. That developer mind-sharing activity is growing. They're making steady progress on security and the introduction of use cases like DeFi have injected a lot of factors into decentralization and activity that we don't necessarily have time to analyze yet. So it's safe to argue that Ethereum is far ahead of most of the protocols in terms of this network and ecosystem of decentralization. Fourth conclusion is that over the next, over the lifetime of the network we've seen much greater complexity and more layers of activity happening off-chain which we can't see here. That will just get more true over time. So in some sense, this stuff might get even harder to track but that also makes the security and decentralization of the base settlement layer that much more important to watch and make that. We also wanted to point out that it's really important to have this historical data about the network so we can all watch these metrics continue to evolve. And I would say Ethereum is much better tracking data than any other protocol but it can still be surprisingly hard to find let alone make sense of this very zoomed out big picture stuff. So Etherscan shared some of their non-public historical data tracker data with us which we really appreciate and we also want to say thanks to our colleagues at the Letio, especially Danny Sweet and Moomoraki for helping us pull all this data and create these regulations. So as you mentioned, we didn't have time to go over a lot of the other graphs that we had pulled and analyzed for the study of decentralization. So we have about a dozen or so more that didn't have time to look but we're going to build a page on Letio which is a data analytics platform where anyone interested can view those graphs and then hopefully in the near future we'll have a lot of tracker of these metrics over time so we don't have to constantly update them and reanalyze them. So it's just a few of the other graphs we don't have time to analyze including function calls on the top left that small one does include transfer and on the bottom right just remove transfer to get a clearer view of the other function calls. Look at ETH training volume over DEXs and then gas fees and then just a different way of looking at the top address concentration. So we really hope this is something of interest to the network that people continue asking questions about it, continue exploring it, and I suggest some additional metrics or ways to quantify those subsystems over time. And if you have any questions, please definitely reach out to us and enjoy the rest of DEV.com.


There is rules and regulations guarding mining activities in Ghana. With Gold Bank, we take those regulations and rules into action so that we don't destroy the environment because of our mining activities. From day one, that was our concern. We were trained the way to do the mining practice. When the MIRRA Commission and the EPA comes for inspections and all these things, they go and tell the neighborhood groups that they go to Gold Bank and see how they are working. You should learn. That is the main good practice to do mining. So that is why Estrago has given us a very big location in their concentration. We have about 2,000 acres, but the small groups, some of them 100 acres, 50, and maybe 25 acres. What I like about the small mines is it makes job creation to the small communities because the small scale mining doesn't need too much of expertise. We pick 70% of our workers from the community. We have them and we train them to know how to do mining. Safety is our priority. We make you understand that anything you do, you think about it, you think about your safety. So the small scale is very good. I would say it is very good because it can be done anywhere, in a small community. And before the mines stays there for two years, three years, they will help the community to get some social amenities, like they can build the schools, give them boreholes to get good water to drink, they can give them a clinic. I love to see activities going on in the mine, like machinery, the movement, vehicular movement, and how people go about the work because it is my initiative. I have trained them, I have taught them how to do it. You just pick them, lay men, non-scale guys, we pick them from the village. Within the first two weeks to three weeks, by four weeks, you will be able to know the do's and do's in the mine. So as the supervisor or the foreman of the project, I go around every hour, one and a half hours, go around to all the sessions and see how they are faring. That makes me very healthy and interesting because I do a lot of walking.


December 15th. If we take up items in the order they are on the agenda, each agenda item we ask the people who are going to speak or participate, organize them and bring them into the meeting and if appropriate they will get sworn at that time. We also ask that when people who want to participate in the hearing that they will give Scott their mailing address. Is that true Scott? The mailing address so you can follow up with some. Next item is the communications, communications in the packet. That was already posted though. Minutes, I think there were minutes in the packet. Is Allie at the meeting tonight? No. She should be. Oh okay because I did sign and send some minutes to Allie a little while ago. I'm hoping that we're up to date at this point. And the next item is the consent agenda. The first item on the consent agenda is 57th South William Street. Vermont Organization for Jewish Education. Shabbat of Vermont is the applicant here for that. Who's the applicant for this Ryan? We got Ed Wolstein. I see his name. Public commenters going to be Lynn Faust. I'm not sure I've seen anybody else. So Ed Wolstein can speak.  Okay so if you want to speak on this item raise your hand I see a couple. Okay raise hand here we go. So as we get started here I'm going to say this is on the consent agenda. This is a previously approved item that I believe expired and now it's the same applications before us. It is recommended for consent. Is the applicant okay with treating this as consent? Is that you Ed? Yes I guess so. Okay are you okay with it being treated as consent? Sure. Okay. Can you define what consent is? It means it's recommended for approval and the staff has several conditions that they've already put into the findings that they should have sent to you. And if you're okay with that then it would just get approved as a matter of you know the board would approve it right now. Okay. But before we go there are there members of public who are wishing to speak on this item. Public are they part of the applicant? There's there is Brad there's Lynn Faust at least sent that email that should have been posted to the site. Looks like she's on so I imagine she wants to comment. Yes thank you very much. I'm Lynn Faust on the Butter at 71 South William Street. Okay at this point before you go too far I just wanted to find out if we're going to treat this as consent or not so if you want to speak on it we will pull it from the consent agenda and treat this as a public hearing item since you want to speak on this right Lynn? Correct. Okay so we'll move right to that so this is now a public hearing and I will ask whoever is going to be speaking on this I understand it's Ed it's Lynn and is somebody else on the phone who is on the phone here? Karen Buscher. Oh Sharon okay and are you going to speak on this also? I was. Okay so we'll ask at least those three people to raise your right hand and do you swear to tell the truth and hold truth on the pain and penalty of perjury? I do. I do. That's you too Lynn. Yes I do. Okay so I would say Ed if you're okay with this that maybe the first step is to hear what Lynn's comments are and then I'll let you respond is that okay with you Ed? Absolutely. Okay so Lynn the floor is yours. Thank you very much I'm on the board of Chelsea Muse Townhouse next door and when this matter was first considered we had looked at the plans and realized that the elevation of the parking area was to be raised considerably compared to the original grade and we had requested some blockage of the headlamps to the cars at that time the plan was created to have some vegetative blockage of the headlamps however the parking lot has been built and it has been in use and what we're realizing now is due to the elevation of the parking area and the fact that there's such a such a sharp slope between the parking area and the our parking area and the residences where we are that it is going to be a very difficult thing to screen only with vegetative growth so we are strongly requesting of the board to consider either guardrails or a fence a solid fence on our side and probably also the the westerly side of the parking area to block those headlamps. Are you you're to the south am I right? We are to the south correct. Okay and the parking lot has been built? The parking lot has been built they've been using the parking lot for some time now and we're getting complaints from the the headlamps going into the bedrooms into the other rooms and given that the plan is that that parking lot is going to be used mostly for the residents who are going to be gumming and going all hours of the day we think that this is going to be a continuing nuisance for the people in in our in our units. Okay um and was was vegetation put in when the parking was constructed? No okay. It's very steep slope it's about a 45 degree slope it's it's the limit of what the slope should be. Slope down to your property. Correct. Okay so maybe give the applicant a chance to respond to that. Okay sure first thing I want to say is we have no problem putting up fencing solid fencing to mitigate any problem from headlights of cars going to going to the south and so that's not a problem we can put it up we can put up temporary fencing right away the vegetation won't go in probably till the spring obviously this project's been delayed that's why we're here today because we were hoping that the whole project would be done by now but seeing that COVID slowed things down during this this past summer very little construction got done unfortunately but we're moving along at a at a snail's pace and we will gladly put up fencing along the south side. What I've noticed is fencing along the the west side if you look at the houses all the way at the back of the property I don't think we'll do much we don't mind putting up some fencing there but I don't think it would really accomplish anything and secondly none of the cars actually face west when they're parked they they would only come into the driveway you know coming heading west and then they would turn around and go into their slots so what what we would think would be a good thing to do would be immediately put up the fencing so that 71 would would be shielded because we're sensitive to to their their needs as well and they would be on the upper part so four feet of fencing guardrails really don't do too much but but opaque solid fencing will will do it so we could do that all along and then when when the actual vegetation gets planted in the spring excuse me it might take a while for that vegetation to actually do its job in in in shielding 71 from the cars that are facing south but we could we could put in permanent fencing at that point nicer you know fencing not temporary construction fencing and we would have a combination of fencing and the vegetation as well whatever would would you know be appropriate at that time so we have no problem with the fencing all along the south side and as I mentioned along the west questionable whether whether it's it's required or even how effective it might be I would suggest that any ways like Lynn just hang on this is one thing at a time here I'd like to just follow up with Ed's things first does the board have any questions for the applicant at this point anybody on the board okay then um I'll ask Ed the to the west the grade slopes down to the retention area is that what it is that's correct okay and it looks like a pretty steep slope yeah yeah right okay that's correct okay if the board doesn't have a question and Lynn did you want to have a comment there yes um my my my concern is that our units are are at the very back of the lot so shielding at least the south portion of the west boundary of that parking lot would help to to mitigate the headlamps that are coming from that are turning around in that space so the south side would be great I'd also like like the board to consider the west side at least the south part of the west part of that parking lot to be shielded also I have a question and I'm just curious I'm trying to understand what makes this is it what makes this so much different than your parking lot and people coming and going in the headlamps in your own parking lot and yeah so I can I can answer that very clearly before this parking lot was built it was at the same grade as our parking deck it was elevated considerably there to so that it's very very steep so that the headlamps are now at the level of our second floor windows which is different from a very different elevation from our parking area understood thank so this is this it's a situation that they created this elevated parking if if it had not been elevated we I don't think we would have had any issue um Ed uh just question for you would it be possible to planting at the I I suspect that you must put snow over that bank is that what happens for plowing you mean the the bank towards the west to the west yeah yes I imagine that would be where they would push the snow I was just trying to think if they could get a little planting at that end um that might help mitigate some other lights to the west that she's talking about I understand fencing at that point does look like it'd be difficult given the slope and everything well we could we could have fencing like all along you know the entire south side um but but as it as as it gets lower you know Lynn is right because the lights would would be able would go across but I do want to point out one thing that that isn't isn't so much the case the residents who live um in some of the apartments of that unit are not in the expanded part they are in the the part that's right on south william street in the old building so the parking spots closest to the street if you're looking at the site plan right now um those would be the first ones to be used by tenants because obviously they don't want to walk all the way you know from from the end of the parking lot all the way up to south williams and have to go into the building that way the expansion part is um is just a um an auditorium on the upper side the sanctuary and there are some multi-purpose rooms and some offices on the lower level um so I wouldn't be so concerned of of people going coming and going at all hours of the night um in fact they've what I'm told is they've even reduced the number of of residents you know who who use the facility um in the as of as apartments all together and it's becoming more and more of of uh of community you know kind of school prayer place um so it's more of a multi-function of that type so um I want to lay some fears to rest that that it's not like people are going to be it's not a it's not primarily a residential apartment building where people are coming and going at all hours I'm just gonna pose on any questions from the board at this point and one more um I'm looking at uh a couple of pages up in the same plan and you can see a better you can see the parking lot better and the fenced in dumpster better you can see it on this one as well um I'm just wondering from Lynn your perspective if that fence sort of came you know continued to cover the south end and then made it to where that dumpster is is does that do you think that that would block that light for you where is the dumpster is it I it's uh my apologies I'm using a small screen yeah um can you go to page eight scott of 17 of the pdf page eight okay yeah um no that's not eight that one right there so you can see right there there's a fenced in dumpster they're saying there's fenced in dumpster I'm wondering if uh yes I I think if you fenced it in up to the dumpster you'd be fine okay uh because the turnaround I'm worried about the turnaround so we're already getting complaints from the guy that's on the end unit closest to the back of this lot that it just it's just you know shining so brightly anyone that's in that parking lot that's reasonable I think there's one other member the public Sharon did you have comments you wanted to make well um can you hear me am I unmuted you're unmuted okay thank you hi this is Sharon busher and at the time the application came forward in 2016 I think or whatever um I was a city counselor representing this section of the city and um you know I spoke on behalf of um uh in support of the development but also about some of the concerns that were raised at the time by a butters and as a person that has represented um people for a while um I am well aware of how disruptive headlights can be so I drove by today and looked at the the height of the existing parking area and realized you know how how those headlights would shine right into the residences and um it really is disruptive whether you're young or old um I know that you know we all live in a city and in close proximity and um if you have children it would wake them or startle um so I'm very happy to hear the applicants say that they are willing to put up a permanent fence because I think a permanent fence and whatever vegetation people want is fine but I really wanted to call in in support of the a butter and hoping that the applicant would be understanding and willing to make those modifications and I think this is turning out well for everybody so thank you thank you Sharon okay uh there's no other questions from the board I think we have a pretty good picture I have an understanding of the willingness of the applicant to address some of these concerns and the concerns of the neighbors we appreciate that um and unless there's anything else that we want to add we will close this public care I appreciate it we the odds are pretty well that we will deliberate on this at the end of our meeting tonight so you uh give us your uh mailing address lickety split uh yes uh 49 Fairmount street in Marlboro massachusetts yes what was the zip code oh 1752 okay great thank you so moving on to the next consent agenda item which is 24 sunset cliff row application by jack and kim kane is the applicant here see jack kane don't think we had any public comment on this one is there anyone else besides you it was both the sands raised scott we see in gen the hands go from then they go down it's like chasing him around all right lucy where'd you go lucy three people is israel part of this application scott or is he for the next one no i let me undo that one okay but the name shift up and down so uh we have three people here jack kane is the applicant and lucy thayer and gen gen desitell are lucy and gen are you part of the applicant or are you a butters we are with the applicant we are both with trudel consulting okay okay so this is on a consent agenda so i'll ask jack the question is this has been recommended for consent by the staff and have you gotten the staff report and seen the recommended conditions yes jack is that are you saying yes who said yes there just so i know i did lucy i lucy okay he doesn't seem to be muted but he's not saying anything uh my understanding is the applicant is okay with the conditions as recommended by staff so this is gen desitell we have all reviewed the staff comments and don't have a problem with okay being on the consent agenda i'm not sure why jack isn't able to respond okay uh does the board have any everybody on the board have any objections to treating this as a consent agenda item it does look like there's someone else with their hand raised now i was just going to mention that brad is somebody with their hand up and who is that carolin carolin beaver she's also with the applicant okay okay so it does not appear to be anybody from the public who is speaking on this application everybody here is part of the applicant can i have a motion from the board for this application somebody make a motion i'll move on 21-0464ca 24 sunset cliff rude i move that we approve the application and adopt staff findings and conditions is there a second second Caitlin okay discussion all in favor i proposed no okay so this is approved thank you thank you thank you we have one other consent agenda item which is 12 22 north street uh application by the brookton school district this was previously approved uh as consent but thinking it was under a previous application that was since it wasn't removed it was uh it was on the agenda november 4th for drb along with two other locations bhs was looking to locate we re eliminated it from review because there was a previous application for educational use but our sharp eyed compliance officer subsequently found a letter associated with two properties that relinquished the permits so we are required to bring it back before the board so is marty spalding are you representing this project yes i am i we also have with us uh jason gingel who is the tech center director but i can probably speak okay so this this is recommended for consent um and did you see staff's report and they recommend conditions of approval yes the bike rocks yep and you're okay with that yep absolutely okay and there's nobody here from the public on this one is that true it's one of the mysteries of zoom who is out there um okay and is anybody on the staff object to treating this as a consent item no staff no well board okay thank you for clarifying that mary if i fully support consent thank you so can i have a uh motion from somebody on the board i'll make a motion on uh zp 21-0377 cu uh 12 to 22 north street i move that we approve the application and adopt staff's findings and conditions for second brooks seconds uh any discussion all in favor hiu okay opposed so it passes you're all set then thank you very much you guys have a good evening thank you okay so the next item is our public hearing item is 132 north champlain street uh which is an appeal of an administrative decision for a home occupation um and is the appellant here so i'm a few months ago is that bella cloe no it's the the list of names shifts around depending on who puts their hand up versus knock and sometimes someone shouldn't get tagged who did all right so we have israel and we have larry pat the owner israel and larry okay is anybody else who's going to speak on this application besides israel and larry uh we have ten miles in the event the questions come up about ted yeah good okay so can i ask everybody who will or might speak on this application to raise your right hand and swear that you will tell the truth and hold truth on the pain and penalty of perjury yes i do okay um and i'm always a little confused on this is this something where the city goes first because it's appealing an administrative position city should give go first to get background on the uh of permit issue okay i think it should go to be a pellant okay so who is it from the city that will speak on this i will take this one okay so um the application was submitted in response to a code violation investigation by ten miles um neighborhood point uh there was a contractor storage yard operation uh operating out of the property um and in response basically to the enforcement the applicant submitted a home occupation that the majority of the complaints centered around employees coming to and from the property to pick up and drop off supplies so that was a nuisance for the neighbor as well as exterior storage in the yard a lot of materials associated with the business but it's important to note that there was also a zoning permit previously issued for the house on the property that some of those materials would have went with the housework so differentiation there a little difficult but it's pretty evident that that might have been associated with the business so anyways um the home occupation permit was uh submitted back and forth between myself and the applicant um to see that he can meet the requirements of the home occupation section in the cdo um the permit was issued on um october 8th of this year uh with very specific conditions that went in line with correcting the violation uh and to achieve a home occupation which means the administrative home occupation requirements of article five um the appellant submitted his appeal in a timely fashion so um uh i mean that basically sums it up i think and isn't is wow this is ready for the appellant but um all the condo is your understanding these conditions were met ryan he's working toward that um i know just he's provided photos today of showing uh the backyard and it's looks to me like it's been picked up considerably but um you know ted miles is here and he's had a uh investigation on the property too so he might be able to shed more light a little bit more light on that is your first uh does anybody on the board have a questions for ryan before we go to uh the neighbor i'm happy to let ted go first if you like well i wouldn't mind israel i wouldn't mind hearing what your issues were okay sure um so the uh the commercial operations that this uh property had been uh increasing steadily over the last couple of years um um the uh i mean it's essentially a contractor's storage yard um it's uh mostly busy during the summer period um the swing seasons uh it's pretty quiet about now as you might expect um so the uh i think ryan sort of summed it up i don't want to go through in you know in the level of detail that i did in in the written appeal i don't think that's necessary but uh suffice to say that um uh there's a lot of traffic uh there there are a lot of vehicles that are parked double parked blocking our driveway oftentimes blocking traffic oftentimes coming and going multiple times throughout the day and multiple employees associated with that as well so you know coming through the backyard um you know basically creating a you know a situation that is commercial activity rather than residential activity there in the backyard um sometimes preparing materials sometimes bringing uh construction debris and hang and you know leaving that there for to be removed later and sent off somewhere else there's all sorts of you know activities that you would associate with a with a construction uh you know a construction storage area um so uh we uh we filed a complaint with zoning about this uh the initial response that we got made some excuses about well you know there's an active building permit to reside the house so it's really hard to tell if this is really a you know something related to that permit or not i i think i think that could have been figured out pretty quick with a little bit of observation um but it took a it took a year plus from that from that initial complaint to get to the point of sending an enforcement letter um and uh so we were pretty frustrated by that um when the uh the applicant filed for the home occupation you know as i noted in my my letter from yesterday you know i wrote after reviewing the staff report um you know we expected him to uh file for conditional use review so that he could have people coming and going and uh you know have employees on site and and do you know some reasonable amount of commercial activity here and then as part of that there'd be you know some give and take about maybe some reasonable conditions like uh like a fence or a parking management plan that doesn't require uh blocking our driveway and things like that um agreeing to a non-smoking work site would be would be nice although i think that might be a requirement regardless um we weren't necessarily ready to stand the way of a conditional use review where there's some uh you know measures taken to mitigate the adverse impact on us the immediate neighbors to the north um i think the the permit that has been granted doesn't really bear any resemblance to the activities that have been going on uh at at the property and i would say you know activities not just that were going on prior to the issuing of the permit but um you know the traffic throughout the fall uh you know it's it was essentially the same level of activity as you would normally expect so even after receiving the permit the applicant was not uh following the conditions of approval um i don't know technically what time there's some grace period where you know he's allowed to to not do that but um you know i think the the period of time that ryan was referring to has more to do with the other violations the physical dimensional violations on the site but anyway we waited until the last moment to file this appeal because we were hoping that the applicant would actually start to reduce the um the level of activity to meet the conditions of approval um so we're not happy to be here this is this is not fun for anybody um we just would like our property interests uh to enjoy our our backyard and our driveway uh like everybody else to be respected any questions for israel smith before i got one um just from israel from from what you were saying about what the primary complaint is it sounds like from your perspective an individual photograph that shows you know the site looks fine is not going to be compelling for you because it's not about as much the materials but it's it's the activity itself comings and goings and that's going to be kind of challenging to uh prove or disprove at any given moment that's correct and and you know to be clear that on paper the permit that's been granted doesn't allow uh employees coming and going doesn't allow them to do anything other than sort of have a office type home occupation um you know which if that's what he wants to do fine i didn't seem to fit what his business actually is it's real uh do you have things to respond to on this yeah i do okay first we raised our hand to tell the truth and that didn't seem to happen okay why don't you say what you want to say here my house has been improved 100 percent since i started working on it it's involved a lot of interior work it's involved exterior work it take it took time and people to do it over extended period of time when you came and looked at the at the property when i had a couple complaints i was still doing the property the siding wasn't on we had five or six people there on occasion after i've told my guys look don't park in this guy's driveway gets really upset about that somehow they parked for brief moments thinking it was just a moment he watches the place like a hawk so my guys during the work on the on the house parked in front of it maybe not blocking the whole thing but maybe edge of the thing we pull i asked them pull out we moved it immediately my property is not used for congregation of employees at all whatsoever my fiance keeps direct control of me on that i probably would have done more had more guys come to my property to conduct business out of it but i live with my fiance respected it's her house she's asking not to have people come over so i have not done that she's the boss i have had people come over and speak to me briefly that need to pick up money to do a trance you know pick up purchases for other projects and leave within a short period of time we don't have massive amounts of numbers of people coming over i think his traffic in his driveway is about like mine on on occasions we have a tenant upstairs which may look like it's added more he has a truck he's not connected with me whatsoever he has ladders on top of it he comes and goes he has some people that he works with that come and pick him up they got the wife upstairs that she has people come and pick her up and take her drop her off but for myself we have anything that happened after the construction we cleaned out my my storage is totally empty it's ready to be raised at any moment everything is totally cleaned out i have three step three extension ladders back in the back and i have leftover supplies that go to my house that i can't put anywhere else that i intend on building putting in a permit to build an additional space upstairs i want to keep it it was a very expensive hardy siding which was approved by mary o'neill and the people in the zoning department which i went through so larry your so what you're saying basically is that the activity and the construction debris and all that stuff was related to the construction on the house primarily primarily it was okay but and that and that you're okay uh adhering to the terms and conditions of a home occupation yeah i'm i'm okay with that yes okay okay um but we don't have traffic here there's i would say if you can say how many people come by to see larry in the day i would say today i had one person twice that was to get my credit card to go pick up a uh to go pay for a bill and another one to drop off my credit card that's twice today a five minute deal nobody else this is jeff hand that sounds inconsistent with the permit condition i understand you made you do that for your business but um we need to abide by the permit conditions part of the concern here is you have not been doing that and it sounds like you're acknowledging you still have employees coming to your home i have an employee come to my house from time to time yes but not two three four five cars at a time not even not even on a regular basis i'm not even home most generally i'm not even home the entire day this has only happened and to yesterday and today i've tried to be home to do my audits and do my paperwork other than that i'm on the i'm on the run in the field all day long from 6 30 in the morning till five six at night i'm not even home so i don't even know what he's talking about i'm not i'm not speaking to what he's talking about i'm just speaking with the statement you just made about the employees that visited your house today today one guy came by the same guy came by twice pick up a credit card went off and i'm admitted it i'm being straight out honest for you that's what happened that and i know i know these are challenging times larry so i understand that but and this is coven times so i'm trying to i'm trying to relinquish my my um i don't want to be in the field all day long i'm getting ready to retire i have hired people to handle my contracts for me all i need to do by the phone do zoom if i have to uh turn paperwork in and talk on the text on my phones my my input my time in the field is now pretty much stopped as of two days ago i've been in the field well i don't get home for dinner till six five thirty six i don't know i'm not even home i don't know what he's talking about i'm in the field talking to my guys okay other questions from the board for the homeowner uh you know i just it seems to me in the pictures that were provided um by the appellant um that it looks pretty clear that there was construction business going on not related to the construction of your house i don't know which time he's which times you have a picture of but i know he watches my house like a hawk uh well i mean you can you can see in his application his appeal application i mean you can see here and it it shows a pretty decent narrative of people doing work loading vehicles leaving with materials coming some of that might have some of that might have been taken stuff out of my backyard that i had like my ladders and removal of the stuff to make it more clean i did go through that i have a warehouse i have a warehouse now in Essex that i store all my stuff in virtually everything except for three ladders i have in the back in my siding equipment everything's in a warehouse eight car michael it's a three thousand nine hundred square foot space so um at this point i think i'd like to have uh ted miles speak um ted you've looked at this property is that accurate that is correct i've looked at this property actually multiple times over the past year starting from the initial complaint last year when israel did file his first complaint about the active yard i did go and found probably six eight people in a very busy construction area working on the house itself and you know he filed another complaint as well at the same time about vinyl windows and that wasn't that turned out to be a non-issue as well um the construction did die down because larry goes to florida for the winter so it was got quiet then so things got closed out because it met the discontinued use over the winter time and then israel started back up with a complaint back in april of this past year about the storage facility uh contractor's yard again and i will say for the record that there was a notice that went to larry on may 6th um about that complaint that was filed and i met with larry on site and there was a lot of debris but it was still very difficult to tell what was associated with the house and what was actually the busy contractor's yard first day as you would call it but larry did do a major cleanup of the property at that time so i'm not sure i haven't seen those pictures that israel submitted but i don't know how old those photos are either it has as of today from your understanding some yard cleaned up in terms of the stuff that yes i actually went by yesterday and took a photo of it and it's it's a lot of it has been cleaned up tremendously um barris amaze and i was there um end of october because as we had filed the complaint with the fire marshal's office uh complaining about um a lot of debris fire hazard materials contractors material and such on site and excess excess of amount um barris amaze and myself met with larry on site and literally crawled through everything on the property and found that complain is uh unwarranted that there was not any evidence to support the idea that there was excess quantities of contractors material on site and there was no nothing barry found that was any kind of flammable tear was a half a gallon of acetone there aren't a pile of ladders on the site at this point no as of as of yesterday in my photo i think there's two ladders on the side that look like they're associated as well with the home i mean i have ladders i have three ladders in my house so and those are on the right hand side of the concrete pad there it's probably in that photo as well that larry submitted so brend please briefly i'm sorry ted i just wanted to point out that we got photos taken i think today submitted by uh by the that is online sorry ted continue yep yep and that's okay and i have been in conversation with larry about those two sheds that one of them was going to be removed and the other one will be put back on the concrete pad where it's been permitted and larry has assured me that's supposed to happen this year so i'm still holding them to that any questions for um ted i guess at this point i i just want to ask israel what your impression is of the effort to clean up the yard at this point um i would say that uh there has been an effort to clean it up and i appreciate it um i i think that's certainly helpful i i would like to believe that uh there's not going to be uh you know materials and equipment run in and out of the the property uh throughout the day as there has been um and you know i i think that uh i think that that the applicant is is painting a very rosy picture of the amount of traffic um i think that uh you know i would it sounds as though he's trying to wind down i'm happy to hear that he has a warehouse in essix now uh you know that's great i i hope that he continues to work out of that warehouse um i what i i guess what i'm concerned about is the it it seemed to take a while for from our perspective for code enforcement to pay attention to this and it really it seemed to require a lot of complaining and you know i don't love to complain but it took it took a lot in order to get enough attention put to this it seems um so i'm glad attention is being paid to it um you know i um i hope that the applicant meets the conditions of approval going forward um yeah but if i if i understand correctly is real that that basically your your goal is is that the conditions of approval for a home occupation are acceptable to you and the issue has been that he is not ready from your point if you've been in compliance with that yes okay and for larry the homeowner you feel you want to and intend to go by abide by those conditions of approval for home occupation yes i do my yard is cleaner than his yard okay okay thank you i sent photos in yes we see those we have those um any other questions for either the appellant or the homeowner from the board i have a question that one question and it's for both is um how what would your response be if the board was to consider a timeline uh condition where this needed to be reviewed to see if the business was being conducted uh as conditioned your response to that i didn't quite catch the question what what would your response be if the board put a timeline of when you needed to come back to the board both you and israel needed to come back to the board um to show that you are following the conditions of the permit i don't have a problem with that uh i just anybody could take a snippet of one moment of one day and make it appear as though it's a gross happening i like the truth i really like the truth i like somebody to look into this i've been annoyed by him he's been annoying me i have no cause to be annoyed i haven't done anything to him and he's constantly if there's trash thrown on my on my yard from people walking by if you can ask ted right now it was trash thrown by a walk a person walking by and he called on me he called on me i wish he'd leave me alone okay israel would would uh uh if we if we considered a time period um would that alleviate some of your concerns around how long it may take to get through um additional um complaints i i think it would yeah i wouldn't you know i would support a condition like that any other comments questions from the board well we'd just like to make a comment before you do please yeah um israel's painting this picture of us that we've ignored his complaints and stuff and that's and it's absolutely not the case larry can tell you how many times have been there to visit him to get action going on this uh israel's complaint first came out on april 29th and we had a letter going on may 6th it doesn't get a whole lot quicker than that uh you know larry can tell you how much of the pain of the butt i've been visiting him and actually pushing him to uh get things into compliance and he's probably tired of seeing me as much as i'm tired of seeing him so right you know larry has been cooperative and is working towards compliance towards that matter the the original complaint was from uh 2019 yes by those active construction going on at the property okay we are dealing with the current complaint where that's our review here so we're going to stick with that okay i appreciate everybody's uh comments and participation and with that we're going to close the public hearing thank you thanks a lot uh and we will probably deliberate on that tonight i think the next item is 75 cherry street and uh there's been a request for deferral is that accurate scott yeah yeah there are ongoing negotiations about my pay grade so the the applicants have requested deferral and it seems to make sense to push it back to the 16th with the other item 16 i'm recused okay 16th of what in february of february okay um we need a more i think we need a motion on that to defer this item to the 16th of february the assembly want to make a motion to that effect keenan um on 21 dash 0354 ap 75 cherry street i move that we defer uh consideration of this item until february 16 2021 second brooks thank you any discussion all in favor opposed and jeff is recused great so that is all we have on our agenda we don't have any other business at this point okay um so we are adjourned um and are people okay with we have


around a corner, come around a corner. Uh-oh. He is trucking it pretty good. He is trucking it pretty good. 21. He's at 21 seconds, folks. He's at 21 seconds. Let's see what he can do. I see the ice bath challenge coming. Hurry up, Joe! You can recover, Joe! Oh, I gotta get to the finish line. 56, 50.5. Uh-oh. I think I'm about to pass out.


My name is Hannah Libby and I am doing one of my last runs for the Boston Marathon. Yes, since February, almost every weekend, I have gone further than I've ever gone. What's the farthest you've gone so far? 21 miles. I'm running for Goodwill's Youth Initiative. Our team's called Running for Great Kids and we are raising money to help some of the kids in some of the Boston-area cities and neighborhoods like Dorchester and Roxbury get better leadership and education opportunities, have some more work experience, things like that. So it's always been like a goal to do the Boston Marathon so unfortunately you have to qualify usually to do it so I think that charity is a great way to do the first marathon. Unfortunately, it's like the time of year where there's a ton of school work so doing my best to get that done as well but right now, the Boston Marathon has an end date coming and the school work doesn't really so right at the moment I'm focusing on the race and hopefully also getting everything else done. When you finish your race, what are you going to do that day? I'm going to Boston Burger Company and I am trying to eat two burgers and I'm going to have a beer.


Myself, Piyusha Shedgar, Assistant Professor, Valchan Institute of Technology, Solapur. In today's session, we will discuss the BABINETS principle. These are the learning outcomes for today's session. At the end of this session, students will be able to illustrate the BABINETS principle. They will be able to discuss the various cases of the BABINETS principle. These are the contents for today's session. So, before going to start the BABINETS principle, you can pause the video here for a second and recall that what is the meaning of polarization of an antenna. Yes, the polarization is the direction in which the electric field of a radio wave oscillates while it propagates through a medium. When an electromagnetic wave passing through any medium, then in which direction how much amount of the signal is radiates is decided by this polarization. So, let us start with the today's topic BABINETS principle. It states that when the field behind a screen with an opening is added to the field of a complementary structure, the sum is equal to the field when there is no screen. In another way, the BABINETS principle states that the sum of the field at a point behind a plane having screen and the field at the same point when a complementary screen is substituted, it becomes equal to the field at the point when no screen is present. In detail, the BABINETS principle we will discuss in the next slide. So, Jacob's BABINET which is French Physicist and the Mathematicians formulated the theorem that similar diffraction patterns are produced by two complementary screens. Whenever the two screens are considered and these two screens are complement to each other, then there will be the similar diffraction pattern will obtain. This is nothing but the BABINETS principle. BABINETS principle relates the radiated fields and the impedance of an aperture or it is also known as a slot antenna to that of the field of a dipole antenna. So, using BABINETS principle how the dipole and the slot antenna relate to each other we will discuss in BABINETS principle. So, the in BABINETS principle the polarization of a slot antenna gives the linear polarization. The fields of the slot antenna almost the same as that of the dipole antenna and the field components are interchanged. Although the fields of the slot antenna almost same as that of the dipole antenna, but the field components are interchanged. That means whenever the antenna having the vertical slot which gives the horizontal electric field whereas, in case of the vertical dipole antenna has got the vertical electrical field component. Now, the different features of the BABINETS principle in BABINETS principle does not consider the polarization of the antennas in establishing the field relations. It dealing with the absorbing screens. It is useful to reduce the slot antenna problems wherever it used the slot antenna problems will be reduced by using the BABINETS principle. So, suppose this is the figure which having the figure one having one of the screen and the figure two having one of the screen. Suppose in figure one this is the metal sheet is considered at the center of this metal sheet the slot is provided. Whereas in second figure the slot is replaced by the complimentary screen that is this slot is having only the metal sheet and around of this metal sheet there is nothing. So, these two screens are complement to each other. This is nothing but the BABINETS principle. BABINETS principle discuss the three cases, three different cases. It depends upon the source placed at one of the point, plane of the screen which is denoted with the S1 and the observation plane which is denoted with the S2. So, the figure A shows the presence of the screen between the observation plane and the source whereas, the second figure complimentary screen is placed between the source and observation plane and the absence of the screen is considered as the third case. So, let us discuss these three cases in detail. So, in above figure you can observe that the S is nothing but the point source, S1 is the plane of the screen, S2 is the observation plane, E1 is nothing but the electric field at any point p, x, y, z behind the screen whereas, E2 is the electric field at point x, y, z behind the screen when S1 is replaced by its complimentary screen and E3 is nothing but the field at the same point when there is no any screen is present. So, according to the Babinette's principle the sum of the field at a point behind the screen and the field at a point behind the screen when the S1 that is the plane of the screen is replaced by its compliment. So, addition of these two screens, addition of these two fields is nothing but the field at the same point when the no screen is present that is E3 becomes equal to E1 plus E2 this is nothing but the Babinette's principle. Now, let us discuss the case one whenever the point source is placed here and the electromagnetic signal is radiates from this point source it radiates the signal to the screen in this manner. So, whenever the plane of the screen is placed between the source and the observation plane you are getting this dashed portion is nothing but the shadow of the signal. This shadow is observed within this signal why because the plane of the screen is placed between the source and the observation plane. So, here the light source and the conducting plane with an aperture before the screen is provided. So, here you can observe that whenever the screen is placed between the source and the observation plane then it passes through this screen and you getting the shadow portion between these two points. Now, consider the second case, second case is nothing but in the previous case S1 is the screen that S1 screen is complemented in the second case that is the complementary screen is provided between the source and the observation plane. Now, consider this is the light source and the conducting plane of the size of the aperture in the previous case being held against the screen. So, here you are getting the shadow in this portion instead of this portion because the complementary screen is placed between the source and the observation plane. So, the light does not pass through the plane but through the remaining portion. So, this is nothing but the complementary screen when placed between source and the observation plane. In the third case when the no screen is there that is the absence of the screen, there is no any screen placed between the source and the observation plane. In that case the resultant combination becomes equal to the addition of the first two cases. So, that means the electric field or the energy generated without screen is becomes equal to the addition of the energy generated due to the screen placed between source and observation plane and this energy generated due to the complementary screen. This is nothing but actually the BABINETS principle. So, by using BABINETS principle the slot antenna difficulties are minimized. But BABINETS principle at radio frequencies is it not possible to have the perfectly absorbing screen which is the requirement of the BABINETS principle. Hence, it cannot be extended to the electromagnetic problems. So, an extension of this BABINETS principle which induces the polarization and more practical conducting screens was introduced by the booker. So, in case of the slot antenna this BABINETS principle is used to get the proper characteristics of the slot antenna. Slot antenna is nothing but one of the type of the aperture antenna. In slot antenna BABINETS principle is used so that you can relate the slot antenna and the dipole antenna to each other. Not exactly the practically it is possible to relate it between the polarization, but the slot antenna and the dipole antenna is relate to each other by using this BABINETS principle. These are the references for today's session, thank you.
