Post #2044: Eleven times as many annual contracts per square foot of pool?

My analysis of the proposed Vienna municipal pool/gym has no particular plan.  I just read through the same documents that were provided to Vienna Town Council a month ago.  And see what I see.

So forgive the somewhat rambling nature of this.

But, now that I’ve finally read through page 10 of the last of the Town’s 9/30/2024 documents — (well, the last that I’m willing to read — the Kimmel et all document, on this Granicus page. )

I find that, in fact, much of what I have posted here, in reading through all these document, in order, was spot-on.


Yes, the financials for the proposed pool/gym were done under the assumption that we’re the only public pool in the market area, clearly contrary to fact.

First, to clear the air, the Contractor’s materials eventually do say that their estimate of likely demand is based on an area with no existing public pool.

So, from the get-go, given the three excellent FxCo REC Centers within 10, 12, and 14 minutes drive of the proposed Vienna facility, the estimates of demand are undoubtedly optimistic, if for the omission of that stiff local competition alone.  Which means the estimates of annual operating deficit are also optimistic.


They expect to sell 4000 annual memberships to a 5,500 square foot pool?

The other finding is that the proposed pool is small.  Real small.  Water area 5500 square feet, or only about 18% of the total building area.

And yet, the projected annual enrollment in the Vienna pool/gym is far more than the enrollment in all the private pools in and around Vienna, combined.  The Town’s contractors plausible annual enrollment, at the high end, is 1.63 times total private pool enrollment in the Vienna area, for a pool that is just 0.14 (14%) of the combined size of those private pools.

And in addition, the estimated 2000 memberships from Vienna proper, above, from the Town’s 9/30/2024 materials, means that, depending on the level of duplication in the current waiting list names, the Town’s contractor kind of expects the Town pool to attract somewhere between 100% and 200% of all (!) the people currently on private-pool waiting lists in the immediate vicinity, to sign up for the new Vienna municipal pool.   And then, on top of that, another couple thousand memberships from outside of Vienna proper, even though Vienna proposes to charge those folks more than the cost of a Fairfax REC Center membership.

That’s 11 times the density of annual contracts, per square foot of water, as our local outdoor private pools will allow themselves.  (And, as a one-time user of one of those pools, those low caps on contract/square foot ratios are for good reason.  Even at that, my pool was crowded during peak periods.)

(And that 11x figure doesn’t even include the daily walk-ins.)

For sure, unlike those local private entities, ain’t no way everybody’s getting in the pool all at once.  More prosaically, whatever this tiny pool turns out to be, if they meet their sales goals, I’m pretty sure the experience is going to be nothing like our local outdoor pools.

Meanwhile, for our proposed government-run 5,500 square-foot pool, surely we should look to the experience of our nearby government-run 5,000 square foot pool, at the Reston Community Center, run by Fairfax County. 

The Smith aquatic center.  If nothing else, we have reasonably clean information on financial performance of that small pool via Fairfax County budget fund 40050.  Among other things, that’s how I know the Reston pool only covers 40% of (what appears to be a narrow definition of) annual direct costs.

And that the Reston pool gets roughly 20,000 person-visits per year.  (Plus some other types of business, which look like maybe pool rentals).  But the core 20,000/year is (/365) about 55 people a day, or (assuming an hour visit each, open 12 hours a day) about 4 people an hour.  While there’s no obvious direct conversion factor, I perceive a big difference between an average pool user flow of 4/hour (Reston), and a projected (as-much-as) 4000 annual contracts (Vienna).  (And I note that Reston charges about half of what Vienna proposes to charge, see prior post.)

That’s a big discrepancy, for publicly-run pools of about the same size, one in actuality (Reston), one a contractor’s scenario for a proposed Vienna facility.  With the two pools being very nearly the same size.


Conclusion:  An old friend, Rosy Scenario

As I stated in an earlier post, for the Town of Vienna, this has all the earmarks of a done deal.  So, in some sense, it doesn’t really matter if the underlying narrative being used to sell this has — to put it nicely — some serious flaws.

And it’s hardly worth pointing it out, because if the contractors “fix” the revenue numbers — downward — I’d bet serious money that they’ll simply adjust the costs downward by the same amount, to leave the same net result.  And if that sounds just a bit too cynical, just watch and see what happens. We saw that before, for Town=hired consultant support for MAC zoning.

And if you look at the whole story of how we got here, you have to start with the basic story being tainted from the outset.  When people responded “pool” on an open-ended survey, my guess is that they didn’t quite envision what’s being proposed here.  Starting from the $1K/year price tag for a family membership.  And now including the small pool size, the astounding proposed density of contract holders/pool square foot (compared to local private pools), and what is shaping up to be a far-larger-than-projected annual operating deficit, due to our old friend, well-known in the DC area, Rosy Scenario.

We aren’t even having a discussion about (e.g.) appropriate role of government.  Nothing so basic.

We the people, apparently, want a pool.  So we have been told.  So, we’re going to get a pool.  This pool. With 4000 annual memberships, and 5,500 square feet of water surface, and a $1K/year annual membership fee, and so on.

And, based on the site plan, 100 parking spots, for 4000 annual memberships, for pool and gym users.  Where my local private membership pool has about 100 parking spots, for 450 annual memberships, pool only.  That discrepancy is in line with the contracts/pool square foot, but I’m just having a hard time getting my mind around the gulf between those two.

Who am I going to believe, the contractor, or my own lying eyes?

Sometimes I feel like I’m the only one in the Town of Vienna that, I don’t know, reads the details and gives it some thought.  Instead of just nodding my head.

I react to much of Town of Vienna decision-making as I do to an embedded splinter.  It’ll just fester if I don’t get it out.

But now, with this post, I’ve gotten it out of my system.  By finally plowing through the last contractor-provided document, I feel as if I’ve removed the splinter.

The decision-making process here still looks just god-awful to me.  But at least, with respect to the most glaring inconsistencies, I’ve gotten this off my chest.

Nobody will ever thank me for pointing these things out.  So I guess blogging is its own reward.

We now return to our regularly scheduled content.

Post #2043: A break for some relaxing pool arithmetic.

 

The bottom line on this post is, are you kidding?

I set out to see how many names, total, were on all the waiting lists of our local membership-only pools.  (Of which, my family is a member of Vienna Aquatic Club).

Answer:  Nearly 2200 names.  There’s no barrier to signing up for multiple waiting lists, so how many unique families that is, I don’t know.  Also unknown is whether they’d have an interest in an indoor Vienna government-run pool.  But there are 2200 or so families, some likely duplicated across lists, on local area membership pool waiting lists.  Families that appear prepared to spend $1K a year or so on a pool membership.

Which seems like good news, if you’re talking about building a new pool.

But the sleeper statistic is in the right-hand column above.  There, I have taken the water surface area of each local club’s main outdoor pool (or in the case of Dunn Loring, pools), and compared it to the total membership.

All of our local membership pools have a limited number of memberships.  All of those pools work out to be around 16 square feet of main pool space, per membership.  (Water surface area, excluding baby pools and such.)

And that’s because of pool capacity constraints.  (And, likely, parking.)  But my main point being that you can’t cram but so many bodies into the pool at once.

I can attest for Vienna Aquatic Club, the main pool gets very crowded at peak times.  Really crowded.  So I think that, in terms of drop-in-any-time, swim-when-you-want pools, all of our local pools have calibrated membership size and pool size just about right, to handle the summertime demand peaks.  Barely.

The lesson I’m taking from this is that the revealed capacity limit of our local outdoor pools is one membership for every 16 square feet of pool water surface area.

Now turn to the proposed Town of Vienna municipal pool:

Source:  Town of Vienna Schematic Design Document, for the 9/30/2024 work session of the Town Council, on this Granicus page.

Do the arithmetic:  5500/16 = ~340.

Turns out, the plan isn’t for Vienna to have a municipal pool.  It’s for Vienna to have a small municipal pool.  Really, almost a tiny municipal pool.  And if I take that 5500 square foot pool, and use 16 square feet per family membership as the capacity limit that appears to be a common denominator for local private pools, then that proposed Town of Vienna pool is big enough to accept … 340 family memberships.

Are you kidding me?  Did I slip a decimal place somewhere?

I’m not even going to get into the financials here, except to say, that’s a train wreck.  Unless people are really keen to spend money on a gym-only (no pool) memberships to this new facility, if pool memberships are limited by pool size for this municipal pool, as they are for all the private pools in the area, the Town can’t sell anywhere near enough memberships to cover the cost of this.  Not even close.

Maybe somebody can say they have some clever way around this.  And that because fill-in-the-blank-here, the Town can sell vastly more memberships per pool square foot than local private pools can.

But, at first blush, this proposed Vienna municipal pool is much too small a) to make much of a dent in pent-up demand for pool memberships, and b) to be anywhere near economically viable.

Alternatively, maybe the Vienna municipal pool will never be the sort of pool where you send the kids to cool off on a hot day.  Because if everybody does that — it’s just like the private-sector pools in the area.

So, at a minimum, if there is a plausible financial plan lurking somewhere in the background here, it’s for a pool whose operation is vastly different from our local private pools.  And one that somehow manages to sell a lot more memberships per square foot than our local private pools do.

In the Town’s materials, I didn’t see any mention of the size of the pool setting any sort of constraint on annual memberships sold.

So I just … have no idea.

Summary

Today’s surprise is that the proposed pool is quite small.  If it were one of the local private pools, it could have no more than 340 family memberships, due to crowding during peak use periods.

How many the Town is hoping to sell, for a 5500 square foot pool, I have no clue.

Anyway, good news is, there’s a lot of unmet demand for membership in private outdoor swimming pools, in the Vienna area.

Bad news is, I have no clue what the Town thinks is going to happen, after it builds a pool this small, with projected operating costs that high.  Other than taxpayers take a beating.  Which, increasingly, appears to be in the cards.

I’m not sure I want to look into this any further.

Addendum:  The money-losing Reston community pool.

Noted in previous posts, Fairfax County financial data show that the Reston Community Center pool covers about 40% of direct operating costs.  (Google reference for .pdf of relevant Fairfax budget document.)  And, that pool was just about 5000 square feet in water area, prior to recent renovations that added a further 1700 square feet.  (Per this reference.)

So the proposed Town of Vienna pool is about the same size as the Reston Community Pool.  (For whatever reason, the overall pool/gym building for Vienna is about twice the square footage of the Reston facility.

The Reston facility received about 20,000 person-visits to their pool in their most recent fiscal year (per Fairfax Budget Fund 40050, reference given above).  Which, if they had received $10 per person-visit, would have yielded about $200K in revenues. The actual revenues for aquatics were listed at around $400K.  Against (what I assume is a narrowly-defined) direct cost of about $1M.

The Town’s projected operating budget for our facility, with a similar-sized pool, is more like $2M.  Everybody seems to think the pool is the big draw, for memberships.  But if our visits and revenues, for a pool this size, match those in Reston … taxpayers are going to take a beating.

I guess when I saw that the Vienna plan was for a 30,000 square foot building, I figured that the pool would be the majority of that.  Being as how “pool” is how Town staff appear to be selling this.  But instead of the pool surface area being about half the square footage of the building — as with the Reston facility — the new Vienna pool/gym is going to about 18% pool.

I didn’t expect that.

So the plan for the Vienna municipal pool/gym is to have a fairly large building, with a small pool. If built to that scale, it can’t handle a lot of pool memberships. And if we get about the same level of business as Reston, with a pool about that size, but our costs are $2M a year …

Yeah, the taxpayers are going to take a beating.

Anyway, I didn’t think that this facility, sold almost entirely on the basis of people mentioning “pool” in an open-ended questionnaire, is going to have a small pool as part of the overall 30,000 square foot building.

I really didn’t expect that.

Post #2041: Think of it as evolution in action.

 

I think it’s time to face facts about this whole “internet” thing.

America, as it exists, was not set up to deal with it.  And now our Democracy is failing, and surely looks like it’s going to be replaced by an oligarchy.  With the most recent muscling of the Washington Post into silence being an excellent example.

To be clear, the internet revolution:

1: Has largely turned journalism into a charity.   What’s left of journalism.  In the case of the Post, it’s a private charity.  But in no sense does the Post make enough money to survive on its own.  Particularly, with the current incompetent management.

2:  Has made it almost unimaginably easier and cheaper to spread lies and rumors.

3:  Has spawned entire professional classes whose job it is create attractive disinformation.  So it’s not just random lies and rumors, it’s stuff carefully crafted to be “sticky”.  It’s material developed with considerable expertise, professionally designed to attract and mislead.

4:  Has allowed the crazy to cluster and self-reinforce.  With the help of Jewish space lasers, and Q, and weather control, and … the list seems almost endless, in hindsight.

5:  Reinforces a winner-take-all economy.  Ebay, Amazon, Facebook, and similar are essentially natural monopolies, like electricity.  Just unregulated  The result is an economic and societal landscape dominated by oligarchs, with a concentration of wealth that would have been unimaginable in (say) the post WWII era when America dominated the globe.

6:  Requires a huge Federal budget deficit to support the extreme concentration of income in few hands.  Because the rich have such a low marginal propensity to consume (that is, they spend only a sliver of their income), somebody has to borrow and spent a ton of money every year, or the large net savings of the rich would tank the economy.  (They put the money in the bank, somebody else has to take it out of the bank, or there’s not enough spending to support current income.)  Thus, we’re on an unavoidable path toward bankruptcy, as a country, because the large annual Federal deficit is needed to offset the annual net savings of our collective super-rich, to whom an increasing share of GDP flows.

Or maybe we just like spending money.

But having such a large share of the money, end up in so few hands, produces in the U.S. a political system driven by the desires of the oligarchs.  The fact that the Supreme Court blessed having the rich buy elections (via Citizen’s United) isn’t really the root cause.  It’s just another manifestation of the power of our domestic oligarchs.


Conclusion

People get it wrong, mostly, when they brand Trump a fascist.  Not that his well-documented admiration for Hitler doesn’t put him in that class.  And sure, attacking the news media, promoting a rabidly racist world-view, antisemitism, blaming all our problems on “the enemy within”, those are all straight out of the Mein Kampf playbook.

Hitlererian strategy, minus the Lebensraum.  That pretty much sums up what’s left of the Republican party, at the national level.

But he, like his idol Putin, is an oligarch.  One of a set of super-rich people who want to run the show.  The trappings of fascism are just there to attract the votes, mostly, I think.  Though the racism seems bred to the bone.

And, one way or the other, he has the cooperation of most all the other oligarchs.  Those that aren’t completely on board, he seems to be able to co-opt, or threaten into submission.  And so, because journalism is a charity these days, and the Post exists at the whim of its oligarch-patron, if that patron bends the knee in order not to have its lucrative government space contract threatened, then so does the now-all-but-irrelevant Washington Post.  Because, at root, oligarchs wouldn’t have become oligarchs if they hadn’t had the same central preoccupation — having as much wealth as they possibly can.  So, effectively, once they’ve divided up the pie, they’re all on the same side.

And so, America is in transition to becoming one of the best countries that highly-concentrated-wealth can buy.

I still wonder about how those West Virginia coal miners feel about all the help that Trump never gave them.  I’d bet they’re still going to vote for him.  And that’s about all you need to know, about what kind of a country we’re about to become.

In a world where Rule #4 applies — Yes, they can be that dumb — we simply lack the resiliency to adapt our Democracy to the internet.  Let alone AI.

Our ultra-rich — with the help of the Supreme Court — have now taken advantage of the inability (or maybe unwillingness) of our populace to sort fact from fiction.

Think of it as evolution in action.  We’ve created a world filled with spam, scams, and carefully-crafted lies.  Our population isn’t up to the task of sorting that out.  Even if it wanted to,

So we get the government we deserve.

Post #2040: Reposting a little perspective on growth in the Town of Vienna budget.

 

As our Town Council works up the nerve to OK the single largest expense in Town of Vienna history, I thought it might be a good time to repost this.

In a nutshell, adjusting for inflation, over the past 60 years:

  • Town population increased 43%
  • Number of town residences doubled.
  • Value of residential real estate increased five-fold.
  • Town of Vienna operating budget increased ten-fold.

Post #1820: Dribs and drabs of Town of Vienna historical data.

And, I guess it’s worth saying, pretty much everything we pay the Town to do for us would already be included in taxes paid to Fairfax County.  The sole exception is, I think, trash service.  The Town may do it nicer, or better, or something.  But if Vienna ceased to exist, Fairfax County would still maintain the roads, pipes, police and fire service, and so on, for the taxes that we all already pay to Fairfax.

From this perspective, to make the single largest capital investment in TOV history, to produce something that’s all-but-indistinguishable from a Fairfax County rec center, right down to the annual fee to use it … I guess that’s not unexpected.

Edit:   Now that I re-read that, I’m not sure it’s the largest in Town history.  I didn’t literally check, memory fades.  And when you get right down to it, you need to CPI-adjust everything. 

But memory fades, and costs are often pieced out across multiple fiscal years.  

But surely, of recent projects (police station, expanded community center, and now this), surely, once I start talking about the expected annual operating loss, then at that point, this building and all it entails surely dwarfs the other two, CPI or no CPI.

If the interest rate is 5%, the value of a perpetuity is 20x the annual payment.  If I take (what I see as the grossly optimistic) assumption of the Town’s consultant, of a mere $500K annual loss, a commitment to pay those losses in perpetuity is worth $10M now.  (And accordingly, if the real annual loss is more like $1M, that’s about like then town shelling out an extra $20M now.)

It’s a big decision.  Let’s leave it at that.

The decision to buy into the government-run gym market appears to me to be, right now, the single largest purchase the Town ever makes.  For a long time, anyways.  

So in theory, it needs that level of due diligence.

If nothing else, I’d like to see the Town Council put together a local panel of experts, meaning, representatives of nearby local governments that already run municipal pool/gyms (a.k.a. rec centers).  Then ask them discuss two topics:  Annual operating cost, and annual operating revenue, from running one (or more) of these pool/gym/rec-center things.

Heck, that could be interesting. 

Post #2039: Pro-pool propaganda is an objectionable use of tax dollars.

 

I should preface this by saying that, for a decade, I held job in the U.S. legislative branch that required me to use strictly neutral language in any official publications I wrote.

In that job, in order to indicate that an outcome was uncertain, I was forbidden from saying “X may result in Y“.  That statement, as written, is not neutral.  It seems to imply that X will result in Y.  Instead, I was, without exception, required to use “X may or may not result in Y“, as the only properly neutral way to convey the uncertainty of that relationship.  Without exception.

So maybe I’m a little sensitive to tax-financed propaganda.

But, in fact, the Town does this all the time.  They certainly did for the now-repealed MAC zoning.  And, if you go back and look at the archives, at some point, the Town newsletter morphed from being a source of information, to being the official house organ of Town government, reflecting its point of view.

Again, paid for by our taxes.

And so it goes.

The deep irony is that the Town routinely runs four or more months behind, on publishing minutes from its official meetings.  So if you actually want to know what’s been said, officially, so far, as a citizen, you’re shit-out-of-luck, unless you feel like spending an hour paying close attention to the video recordings of recent Town Council work sessions.

But the same Town government that can’t get minutes of its official meetings published in less than half a year can somehow manage to get a slickly-produced mass mailing, with every appearance of attempting to drum up support for a municipal pool, done in a perfectly timely fashion.

Anyway, if by magic, today’s mail brought me the following postcard. In addition to a beautiful artist’s conception of the facility on the front, it has this wording on the back, emphasis mine:

There’s no way for me to read this as anything other than advocacy.  “If you  like this, please let Town Council know.” (Separately:  Describing this as Town Council’s proposal is also, I think, objectively incorrect.  Use of citizen “wish list” was annoying in its gratuitous evocation of positive feelings.

Or, in my case, evocation of the Sears Roebuck catalog.

This in no way reflects on the merits or lack of merits of Town staff’s proposal for a municipal pool.  I’ve addressed the revenue projections from that in the just prior posts.  And, for sure, none of the advocates seems to stress that this will be a $1,000-a-year family membership pool/gym, similar to but with less comprehensive facilities than the many Fairfax County rec centers in this area.

In fact, if you read that postcard, it sure reads as if a temporary (not stated:  10-year-long) increase in the meals tax will pay for everything.  But that’s misleading.  Somehow the Town staff did not mention their consultant’s proposed schedule of fees, which, no surprise, looks pretty much like the fees that Fairfax County charges to use its similar (but larger) facilities.

Anyway, if you’re going to set yourself up running a taxpayer-financed business — which is what we’re talking about here — you need to approach it as a business decision.  Not as something for which Town staff advocacy is normalized.

Conclusion.

Again, this is neither here nor there, with regard to the wisdom of the decision.

I’m just pointing out that when I worked for a government entity, if I’d manage to do what Town staff just did — use tax dollars to produce a public-directed bit of advocacy — I’d have been fired, no questions asked.

But in the TOV, this is just business as usual.  We’re so used to it that I’d bet nobody in the Town power structure even gave this use of tax dollars, to sway Town Council opinion, a second thought.

Post #2038: Wading into the Town of Vienna pool, adding on a baby pool

 

The Town of Vienna is considering building a municipal pool/weight room, at an initial cost of around $32M, including the purchase price of the land it sits on.  The projected ongoing annual cost to the taxpayer appears to be in the neighborhood of $500K.  Ish.  But that’s net of a projected annual revenue of about $1.7M.

This new facility would provide people in the area an opportunity to purchase a roughly $1,000/year family membership, or pay (say) $10/head/visit.

And yet, everyone in this locality already has that opportunity.  Except for the location, the smaller size, and the more limited facilities, this proposal from the Town of Vienna appears to be not much different from the existing Fairfax County Rec centers in this area.

But, near as I can tell, the Town’s analysis ignores the existing government-run gyms in the area.  Above, left, is the view of the market area that was delivered to Town Council this past September.  Above right, I’ve added in the three nearest Fairfax County rec centers.

I will again state that these County rec centers are very nice facilities.  The Oakmont rec center is, by far, the nicest gym that my wife and I have ever used.  Our local Fairfax County rec centers offer a broader range of activities than the Town can offer in this location, up to (e.g.) golf courses.

Other than location, the only unique aspect that I saw for the Town’s proposal is that it leans toward having a “fun” indoor pool (= child oriented), as opposed to the more serious (= exercise-centric) indoor pools found at the County rec centers.

Not to put too fine a point on it, but anyone in Vienna who wanted to pay $1K/year for a family membership to a government-run gym and indoor pool has long had the opportunity to do so.  That fee gives your family access to a set of rec centers that is top-notch, and offers a broader array of facilities than than the Town can offer.

This would suggest that any projection of revenues, from the Town’s pool, ought to be done conservatively.

Seems like a good place to start, then, with a realistic project of likely Town of Vienna revenues, is with those Fairfax County rec centers.

I thought I should do a straight-up projection of likely revenue, based on what Fairfax County has experienced with its similar, but better, rec centers.

In effect, these are the revenues to be expected if the Town is able to sell its government-run pool/gym to its own citizens (only!), to the same extent that Fairfax County is able to sell its rec center services, to its citizens.

Here’s how the two compare.

All I’ve done is taken the observed Fairfax County rec center revenues per Fairfax County resident, and boosted them for the higher average incomes in Vienna.

Alternative simple estimate: revenue per square foot.  An alternative way to get at a similar estimate is simply to take rec center revenues per square foot, for the county, and multiply by the proposed square footage of the Vienna municipal pool facility.   Like so:

Again, the result is nowhere near the Town’s projected revenues.  Edit:  In hindsight, I screwed that up, the revenue number should be more like $22M, and the resulting revenue per square foot more like $750K.  Still a long way from the projected $1.7M for the 30,000 square foot proposed Vienna pool/gym.

Finally, there is limited public information available for Herdon, a nearby Virginia Town with a larger, but less affluent population.  Herndon maintains a pool/gym, indoor tennis courts, a golf course, and other amenities.

In total, Herndon’s Parks and Recreation revenues — from a roughly 60% larger citizen population, and a far broader array of offered services — was $1.8M, per their most recent Comprehensive Financial report (2023 report, Exhibit A2).  I get the vague impression that most of that revenue came from the golf course, but I was unable to pin it down any further.  (Edit 10/26/2024:  Upon reading Herndon’s budget, that must be wrong.  They maintain distinct funds for their Golf Course and their cemetary.  So figures pertaining to golf course costs and revenue should not appear on (what I hope was) an analysis of Herndon’s general government fund.)

In any case, this again suggests that the Town’s estimate of revenues, for the proposed municipal pool, is optimistic.  Presumably, all it would take is a phone call, from Town of Vienna to Town of Herndon, to get the actual annual revenues from Herndon’s municipal pool.  (Edit:  If such a figure exists, e.g., if Herndon has a way of tracking specifically revenue for use of the pool/gym facility)

Will our Town Council do that much due diligence before proceeding further?

Maybe they already have, but there’s no easy way to know.  At the current rate, it looks like the Town Council might get around to publishing the minutes from its most recent work sessions sometime this coming spring.  (Thus, staying within the letter of the law, while keeping the citizens in the dark to the greatest extent possible.)  Once the Town gets around to that, Edit: if they haven’t already voted to fund the pool, once they’ve voted to fund the pool, as this looks increasingly like a done deal to me, then maybe I’ll read those to try to find that out whether they bothered to ask Herndon about its revenues, from its municipal pool.  My guess is we’ll never see that, from the Town, unless the answer is favorable to the “yes” decision to build our own government-run pool and weight room.

Post #2037: Wading into the Town of Vienna pool.

 

 

I had a friend ask about the new pool.  Against my better judgment, I decided to try to get the facts straight, about a proposed Town of Vienna municipal pool and weight room.

I didn’t get very far.  But if you read nothing else, pause to consider the two maps below.

Edit 10/24/2024:  What a sheep I am sometimes.  I fell right into this one.  Just copyin’ the slides.

The price tag above  excludes the purchase price for the property (the land), and the cost of demolition of the then-existing structures. The issue at hand is the amount the Town now needs to borrow, but if you’re reckoning the total cost, you need to add in the cost of the land and prep, call it another $6M.

Full disclosure:  My family belongs to one of the private membership pools in Vienna.  We also use the Fairfax County rec centers, which come with pools.  Neither of one influences my thinking, but both give me some perspective, I think.

Winter approaches. 

But no pressure, as I slowly work through the tax angles on this HVAC equipment replacement decision.  And bring somebody in for another quote for new equipment. And maybe, eventually, get everything working again.

If nothing else, this whole episode shows me that it’s good to have multiple heating systems in your home.

Even with one heat pump dead, we have some heat.

Today’s punchline.  My 1959-vintage first-floor HVAC ducts are, objectively, way too small to work with a modern heat pump.  The main duct is roughly one-third the size (cross-sectional area) it needs to be.

We could put the best ground-source heat pump in the world at one end of those ducts, and the kitchen at the other end of the air duct would still freeze in the wintertime.

If feasible, we’re going to replace (one of) our dead ground-source heat pump(s) with a couple of ductless mini-split air-source heat pumps.  Just bypass the grossly undersized ducts entirely.

Sounds like a fundamentally stupid thing to do.  But not so, in this case.  I think.


Never make fun of the size of a mans ducts.

I finally got the bright idea to measure the size of my first floor ducts.  The ones that barely function. Admittedly, guessing about it was more fun.  And even if I knew the dimensions, figuring out the “right” size is an engineering black art.

But I had a hunch that a quick ballpark answer would be good enough.  The main duct measured out at 0.75 square feet in cross-sectional area.  The first floor of the house is about 1500 square feet.  Per two on-line rules of thumb, the original 1959 ducts are about one-third as big as they need to be.

That squares with the rest of it.  Not just their abysmal air delivery, but just by eye, the cross-sectional area of the main duct is about a third that of the plenum to which it is attached.

I can easily believe that the folks who originally installed my ground source heat pump installed a super-duper ground-source heat pump, then blithely hooked it up to grossly undersized duct work. It’s of-a-piece with the rest of the shoddy retrofit they did before selling the house.

But the ducts themselves appear to be much, much older.  They’re behind plaster walls, for one thing, and I’ll swear that plaster has never been disturbed.  They are in an unusual configuration, with both ground-level ducts, and ceiling-level ducts that must be fed by long risers.  The guy who built this house seemed to build pretty good houses.  How’d the original builder manage to put in such goofy undersized ducts in the first place?

I now think that these first-floor air ducts were originally designed and sized for use with a gas-fired hot air furnace.  The air coming out of one of those is very hot, and so quite energy-dense, compared to the lower-temperature air you would typically get with a heat pump.  Not only would you have to move less air to heat an area (thus requiring smaller ducts to move it),  you probably got a considerable “chimney” effect in the vertical risers that serve the many ceiling-level vents.  (Vents that, in the current system, seem to do absolutely nothing.)

In the end, it doesn’t matter.  A few simple checks all tell me that they are, in fact, just way too small for use with a modern HVAC system.   

Twenty years ago, they cut a major corner in the original ground-source installation.  For 20 years, system performance must have been sub-par as a result.  For sure, for 20 years, the kitchen has been freezing cold every winter.

It’s time to fix that as best I can.


Rule number 4:  Yes, they really can be that stupid.

 

A buddy of mine once gave me a little laminated list of rules for life.  Rule number 4 was as stated above.

At root, my biggest problem so far with this two-dead-heat-pumps fiasco is forgetting Rule #4.  Because, when I bothered to check, sure enough, the folks who retrofit this charming home with a super-expensive ground-source heat pump system then proceeded to hook one of those heat pumps up to grossly undersized ductwork. Which made the entire point of installing an efficient heat pump almost completely irrelevant.

And so it has remained for two decades.

And now, completely contrary to the conventional wisdom, it makes sense to  replace a worn-out ground source heat pump with an air-source heat pump.  If for no other reason than to bypass the undersized ducts.

Addendum:  Or duck the ducts.

I finally got it.  The story ends … and you can’t replace the duct, because a properly-sized main duct would stick down too far in the basement.  So not only didn’t they replace the ductwork, they couldn’t replace the ductwork without losing standing headroom right down the middle of the finished basement.

This situation is no-one’s fault.  It is what it is.  Deal with it.
