How much did cutting the middle out of our housing stock cost Olympia in the last forty years?

Or, Olympia's spreading tax-subsidized single-family neighborhoods. 

I've pointed to this chart oftentimes as an illustration of how we changed directions back in the 1980s.

I've recently been rethinking this graph, mostly due to new perspectives on a fairly old policy tool to encourage apartment construction in downtown Olympia. Dan Leahy has been writing in Works in Progress about the multi-family tax exemption and how the rest of us are subsidizing new construction downtown.

While the discussion around the multi-family exemption does not reveal anything new (someone pays taxes if someone else is exempt), it does give a new ax to grind to people who would rather stay the course with how Olympia has been developing in the last forty years. Car-dominated suburban developments get a pass, while any sort of development downtown that is not a parking lot is given a side-eye or actually challenged legally.

But, the discussion did open an opportunity to examine how exactly our spreading suburban development pattern has cost the city's bottom line.

As a background, I used the Thurston County Assessor's parcel data provided by Geodata. This dataset gave me locations and construction dates (important for that chart), but also lot sizes and total values.

Also, I wanted to point out that only in the broadest sense am I talking about "denser" housing. Leahy is mostly discussing downtown Olympia apartment buildings, while I'm discussing anything from a duplex to a quadplex. While we oftentimes conflate these when we discuss housing and zoning, I want to make sure we know I'm talking about different types of housing. 

Now, let's get to the data!

At some point in the early 1980s, the construction of duplex to quadplex sized homes became disconnected from population. I chose 1981 as my splitting point because it seemed to make sense to me.

Between 1960 and 1981 Olympia averaged 6.2 two to four-unit buildings per thousand of population increase.

After 1981, that rate fell to 1.23 units per thousand new residents. Building non-apartment/non-single family home dwellings went through the floor after the early 80s.

What happened in the early 1980s? Go back and see the policy changes we made to favor single-family homes and the hateful political ecosystem that created it.

And because we know how many people have either been born or moved here, we can calculate how many du/tri/quadplexes we lost because we changed the rules. If we built at the same rate we did before 1981, we would have built 723 more du/tri/quadplexes. We currently have 786.

That on its own is shocking. That means we outlawed between 1,500 and 3,000 living spaces since the early 80s. If we continued building duplexes, triplexes, and quadplexes in Olympia, we would have nearly doubled the number of these more affordable units.

But, let us not stop there, this is about the public subsidy, not affordable homes removed from the market by bad laws. Because we know how much single-family home properties are worth and how much du/tri/quadplexes are also worth, we can calculate roughly how much each type pays per acre.

It should surprise no one, but the more dense housing types subsidize single-family homes.

Du/tri/quadplexes cover just over 216 acres of Olympia and they are valued at an average of $1,159,413 per acre.

Single-family homes cover over 4,528 acres of the city and those are valued at an average of $1,035,155 per acre.

This is not taking into consideration the added value du/tri/quadplexes would have brought to single-family homes.

So, when you lay out what we lost (at least 1,446 affordable units) against their higher value, you can get an idea of what our historic single-family home favoring policies has cost our city.

Doing a back of the napkin calculation based on last year's levy rate, the lost taxes (not just to the city, but to everyone who collects property tax in the city) was $3 million per year.

To put this into perspective, in his post that I linked to above, Dan Leahy points out that across of all the multi-family exemption projects, the loss in total government revenue is $3.4 million over eight years.

What we lose per year because we made a decision forty years ago to favor single-family homes is the same amount we lose over eight years for encouraging more dense development. This calculus also ignores the higher tax receipts that an apartment building will produce as opposed to a parking lot once the exemption is over. And, also (obviously) that the tax exemption is temporary, while single-family zoning is a bit harder to budge.

The Indian Shaker Church and the Lewis Family totem pole

Surprisingly terrible people.
And, by way of making this re-telling of these incongruent stories even weirder, they both originally were written about in the same edition of the Daily Olympian on July 5, 1970. 

The Indian Shaker Church on Mud Bay needed to be rebuilt. 

It had burned down in the winter before. And, in the summer of 1969, Indian Shaker adherents had noticed the roof had begun to cave in because of snow anyway. 

The original church structure had been only been built in 1910, the same year the Indian Shaker church was formalized.

So, the community of this particular fairly new faith got together to rebuild. They also reached out to seek help. A Seattle architect sent down plans and Simpson Timber company gave and delivered all the wood they needed. 

On July 4, 1970, Indian Shaker faithful from all across the region came to celebrate the reopening of the church. Because this church wasn't just an Indian Shaker Church, but the Indian Shaker Church. The mother church.

I'm not a tribal member nor a person of this particular faith, so I won't go into the history of the Indian Shaker religion. But, only to say that the religion was only founded in the late 1880s and for years was a robust expression of tribal culture. One white people even feared.

So, let's leave that there for a second and move to a week earlier, on Cooper Point, when something else entirely happened.

While Indians from all over the region were planning their visit to their newly rebuilt mother church, a white family on the other side of the bay was dressing up as Indians and unveiling a brand new totem pole they'd just bought.

And, in only the way that white people being totally unaware of the way they look or how they would be judged almost 50 years later, the Lewis family and their friends not only dressed up as Indians and played recorded "musical Indian chants, alternatively soft and loud..." but they called themselves by terribly derogatory Indian names that I won't recount here.

I should let you read the story yourself, and you really should, but the Lewis family should be judged. And judged harshly. The way they acted is not respectful. If their plan was to honor tribes and tribal history, treating it like a dress-up party is especially tasteless. I don't need to tell you that, though.

Where did they even get the idea to buy a totem pole?

Three years before the party and unveiling (I'm not going to use the term they use, but read the story) one of Dick Lewis' friends needed help moving his own totem pole. Being a nice friend, Dick came through with a truck and was smitten.
"Mrs. Lewis reported that 'totem fever infested the Lewis tribe" and they determined to have one for themselves." 
Dedicated as "unfolding a bit of Pacific Coast history, reminding all of us our precious heritage and need to preserve our God-given rights and freedoms," it provides "a tangible link between past and present" to the Lewises and the many people who are received as guests in their hospitable home.
This talk of freedom and God-given rights is a double serving of irony if you head back across the water to Mud Bay.

I mean, why were Indian Shaker adherents gathering on July 4?

Jeremiah George (Squaxin) wrote a bit in 2010:
When we practiced our culture in secrecy (for our European conquerors were quick to label us as hostile savages, disposing of us as such) tribes came from miles and miles away to a potlatch we called the 4th of July Celebration at Squaxin Island. That celebration must have had an impact, because an elder from Canada in his 70’s-80’s recalled when he was young an “old” elder claimed his favorite place was Squaxin Island. Culture got us through hard times and the assimilation that keeps us distant from culture and the apocalyptic measures of genocide that will continually go unaccounted for. 
They had to celebrate on the fourth of July, because they didn't have the freedom to celebrate otherwise. In the early years of the Indian Shaker church, its members were arrested.

At the same time the Lewis family was appropriating and pounding their chests about heritage and freedom, tribal members were being arrested and prosecuted all over western Washington for fishing. A right not reserved by God, but by treaty.

It would take only a little over three weeks for the fall chinook season to start and for two Puyallup tribal members, Bob Satiucum and Charles Cantrell, to be arrested for fishing. Just as illegal as it had been to be an Indian Shaker, it was still illegal to be an Indian fisherman in 1970. The Lewis family had the freedom to buy a totem pole and dress up like Indians, but actual Indians didn't have the freedom to be Indians.

Ghettos and lost quadplexes at Nut Tree Loop: Our conversations 40 years ago around multifamily housing and how we got here



If you go up Eastside Street from downtown, it will eventually curve to the east and become 22nd Avenue. As 22nd Avenue approaches Boulevard, there is a small neighborhood on the left-hand side of the road called Nut Tree Loop.

This area around 22nd, Cain Road and Boulevard was the neighborhood I grew up in. I was born in 1976, so in my mind's eye, I kind of remember Nut Tree Loop being built in the late 70s. And, I've always thought about it as a much nicer neighborhood surrounded by blocks of split-level ranch homes and older craftsmen. I think if you take a walk through Nut Tree now, that impression by Kid Emmett still holds true. Two homes recently sold in there for over $700,000 (in 2017) and $800,000 (last May).

So then, I was startled to find out when Dan Beuhler first envisioned Nut Tree Loop in 1976, he sketched out a neighborhood of 21 fourplexes "across one section of landscaped grounds." Beuhler had already built a smaller development of apartments around the corner from Nut Tree. At the time called Eidleweiss, they are currently known at the Chateau Townhomes.

 Where 40 or so nicer single-family homes now sit, 84 multi-family units would have been built, if Beuhler got his way. But instead, the Nut Tree fourplexes kicked off several years of debate in Olympia around multi-family housing, the results of which are still felt today.

And the nature of those conversations tells us a lot about why Olympia shut down the development of smaller multi-family housing since the 1980s.

I've written about this period of history in Olympia before. First I tracked the sharp decline in small multifamily housing in Olympia since an explosion in the mid-70s. Second, I took a look at zoning maps since the 1960s to the current day and found a declining area that allowed anything but single-family homes. Lastly, I charted the sprawl of single-family homes that resulted since Olympia downzoned.

In this look, I want to explore how we were talking about the change in the city that at one point allowed duplexes and small apartments and then outlawed them.

Beuhler's proposal set off a series of contentious public meetings where the city planning commission (on which Beuhler inexplicably sat)  decided the fate of the Nut Tree quadplexes. Over 500 individual Olympian's testified to the city planning commission and the city commission itself (Olympia was not yet governed by a city council).

Times were tense when the city commission finally took up the Nut Tree fourplexes. When one city commissioner pointed out that in the late 70s incomes were not increasing at the same rate as the price of a single-family home and therefore it made sense to allow for denser, more affordable options in new construction, an audience member shouted: "Why don't you move to New York?"

New York in the 1970s not necessarily being an example of a humming urban community. This fear of the urban, the denser and poorer community coming into newer single-family neighborhoods underlined the public debate around Nut Tree. While most of the top-line conversation was simply about the power of zoning and the expectations of homeowners that their newer neighbors would have the same zoning, when you dug down, you go the fear of the urban.

Facing that level of fire over one development was not something the city commission had experienced before, and they quickly put the Nut Tree quadplexes on the shelf.

After Nut Tree Loop, the city took a step back and began to examine multifamily housing across the city. The Citizen's Multi-Family Housing Taskforce began meeting in January 1978 and worked throughout the spring and summer to deliver a zoning package to the city council.

But, like Nut Tree along 22nd, this proposal met with fierce opposition across the city.

As the city considered a plan that would expand multifamily housing throughout the city (even further than the citizen's taskforce had intended), an unsigned editorial in the Olympian captured the mood of those opposed to denser housing: It isn't our job to look after anyone but families and experts that disagree with us are bad.
Those who participated in seven months of hearings by the task force evidently want nothing of the philosophy that holds a community responsible for providing the kinds mixed housing needed by today's mixed lifestyles -- the singles, the elderly and the divorced for instance. 
The planners are coming at the problem as theoreticians, as we see it, and they're not handling the grassroots thinking very well at all... The latest effort to insert recommendations into a citizens report had too much of the smell of "we know what's best for you" thinking about it.
The commission approved plans that would, on the one hand, allow multi-family housing, but, on the other, only after it was approved on a case-by-case basis. Even then, the economic class of the folks sitting on the Task Force was brought up.

From the city commission minutes in August 1978:
Paul Sparks said his concern is that we would be isolating the lower income families to certain areas away from services and from the city center. The people who are most affected by (the multi-family plan) were not involved on the Task Force. 
Two unidentified women then entered into a heated discussion about the makeup of the Task Force, one asking how come low income people had not been considered and involved; the other replying the Planning Commission has asked for volunteers to serve on the Task Force and all this was in the papers and the radio.
The city commission passed a version of the Task Force recommendations, but they failed to turn on the spigot of multi-family housing.

By 1980, the planning commission had again passed a package that would expand multi-family housing across the city.  The idea would have been in the early 80s to allow multifamily housing in all areas of Olympia, essentially banning single-family zoning.

And, again the residents of single-family neighborhoods stood up.
Multi-family housing in otherwise single-family neighborhoods will foster "the diverse kind of community that makes this community interesting and makes it rich," (Raven Lidman) said.  
She said when it comes to the good points of living in single-family neighborhoods, "tenants have those same desires." 
But Virginia Baxter, speaking after Lidman, said "The existing inviting neighborhoods will be destroyed, and there will be an exodus of homeowners" if multi-family housing comes to neighborhoods. 
... 
But Susan Hirst, protesting the proposal, said that multi-family renters will not gain much by being located inside single-family neighborhoods. 
They will still be living in apartments, she said, and "you will simply be placing them into a neighborhood where other people have" the style of life the renters want.
But you have to look no further than Bill Grout to find the dark corner of the urbanism discussion in 1980 Olympia. In one article on the 1980 multi-family plan:
"You have increased police activity, increased crime, increased vandalism," with multi-family housing, said Bill Grout.
Later that summer, as the city commission itself considered the plan, Grout crossed swords with a county leader in a discussion that might as well come out of our current conversation about Missing MIddle housing:
Bill Grout, who said he represents Olympia's homeowners, labeled the proposal one which "would turn Olympia into a ghetto."  
... 
(County Commissioner George Barner) said the measure would build up the dwindling rental housing market and would enable low income and young persons to afford a place to live. 
He said such housing should be encouraged in the urban areas because most conveniences are located there. He added it would also prevent urban housing sprawl. 
Grout contradicted Barner, saying out that multi-family housing would drive down property values in single-family residential areas because renters generally do not take care of their property.
And, so the city turned the proposal down. Not actually turned it down, but rather just put it back on the shelf. A year later the city would approve a townhome ordinance that would allow a certain kind of multifamily housing throughout the city, though one that seemingly favored homeowners.

But, the time of multi-family housing tracking with population increase was over. Olympia would go through several incremental downzones to tighten up single-family zoning areas through the 80s and 90s

What does a medical exemption from vaccination mean in the Olympia School District?

Measles can be prevented.

Medical exemptions for vaccinations in the Olympia School District and Washington State might not be what they appear to be.

On their face, these exemptions allow children who cannot be vaccinated (because of weakened immune systems, for example) to waive vaccination requirements and attend school. But, from what I've been able to gather from a public document request from the Olympia School District, the differences between personal-belief and medical exemptions is murky.

So murky that (please read to the bottom), I wonder if doctors or any medical professionals are necessary for the medical exemption process.

Let's work backward first to see how I got here:

About a month ago, while the measles outbreak in Clark County was still new news, I updated what the vaccination rate for schools in Olympia was like. This was similar to other times I'd done this update, there are some scary high exemption rates in Olympia schools. But this time I noticed a new wrinkle: the top schools for personal-belief vaccine exemptions were also the top schools for medical exemptions.

Top Medical (bold if on both):

1. Olympia Community School (12.9 percent)
2. ORLA Montessori (8.5 percent)
3. Olympia Regional Learning Academy (6.3 percent)
4. Lincoln Elementary (4.6 percent)
5. Pioneer Elementary (2.7 percent)

Top Personal (bold if on both):

1. Lincoln Elementary (19.4 percent)
2. Avanti High School (17.6 percent)
3. Olympia Community School (16.1 percent)
4. Olympia Regional Learning Academy  (15.8 percent)
5. ORLA Montessori  (15 percent)

To me, this made little sense. If you were a parent of a child who had a medical reason to avoid immunizations, then I think you'd want to then use the herd immunity at your child's school to help prevent infections. What I could see was that there was a correlation between parents who would seek a personal exemption from vaccines, ones that would seek a medical one, and the school they chose.

That made me assume that parents who are seeking medical exemptions are also not necessarily afraid to send their children into environments where a scarily low percentage of the children are vaccinated. This got me curious about the nature of medical exemptions in the Olympia School district overall.

So, I made a public records request for all medical exemption forms that represent active students in the Olympia School District. These are the documents I received and this is the spreadsheet I put together summarizing what I found (folder with both files here). The district blacked out student names and addresses before they gave me the documents, but they didn't black out the names of doctors that signed medical exemptions.

Here is what I sussed out:

1. Naturopaths are slightly more likely to sign medical exemptions. While 25 percent of the medical exemptions I received from the school district, naturopaths only make up 20 percent of the provider types (family, pediatric and naturopath) that I assume would likely be presented with the form. Some forms were also signed by physician assistants and nurse practitioners.

2. Some doctors sign more than others. Like schools that seem to collect medical exemptions, some doctors seem to sign more than their share. This may be a consequence of who they see (people that are more willing to ask for a medical exemption), but I will probably never find that out. While a vast majority of the doctors who signed the forms only signed one, there were a few that signed several:

Jennifer Ash ND, 7
Lisa Barer MD, 6 
Amy Belko MD, 4
Bridget Sipher MD, 4
Kevy Wijaya MD, 4
Richard Faiola NP, 4

3. What does a medical exemption even mean? Over 75 percent of the forms had both the "medical" box and "personal" exemption marked on the form. This seems to undercut the meaning of the medical exemption form altogether. What may seem like an inexplicable bunching of both medical and personal belief exemptions (why would an immune deficient child attend a school full of unnecessarily unvaccinated children?) isn't. What it really could be is just a larger group of children whose parents declined vaccination for personal beliefs but got their doctor to sign a medical waiver.

Then there was this:


You might have already perused the documents the school district gave me, but if you haven't, this is (as far as I can tell) a full-on medical exemption form with no details, exempt the student's name and a parent's signature. No medical professional's name, no medical professional's signature. This isn't even a double-marked personal/medical exemption. This is a pure medical exemption that is on file at the Olympia School District, that purported to clear a student to have not been vaccinated for medical reasons, with no medical professional's name on it. 

If a parent can sign a medical exemption form and it be accepted by the school district, what is the point of even requiring them at all?

Where Olympia has lost population

When you think about population change in a growing region, you think of it as a constant. And, even though Olympia has been lagging behind Lacey in growth rate for the past few decades, Olympia is still on a gradual population climb.

But, that population growth has not been consistently spread across the city. In fact, there are numerous neighborhoods that have actually lost a significant amount population in recent years.

To explore this phenomenon, I built a map in a tool called Policy Map. The variable I used was the rate of change in the five years between 2013 and 2017, according to the American Community Survey. These are interesting years because it was a time when the incoming population of our area outpaced new housing. So, at least in theory, our available housing became more crowded, not less.

A small caveat about this data. It is based on survey results collected by the Census Bureau. Being survey results it is less accurate than actual decadal census data. That said, all of these neighborhoods have seen measured losses of over 13 percent, which would probably outstrip any margin of error.

The first neighborhood in Olympia that lost a significant amount of population (again, more than 13.46 percent) was this one up in far northeast Olympia.


This Lilly to Southbay Road neighborhood is the outlier in the type of neighborhood that has lost population though. The much more typical neighborhood (in dark brown below) is an older, inner residential neighborhood.


Here's the map key:

I've written about these neighborhoods before and in my mind, these are the neighborhoods that beginning in the late 1970s started seeing the impacts of growth cascading out of downtown. They experienced an influx of what we now call "missing middle" housing, multiplexes and small apartment buildings. But, instead of welcoming the growth and naturally more dense neighborhoods, these neighborhoods downzoned and pushed additional growth towards the edges of town. This new growth, in turn, paved over farms and forests.


But, why now are these neighborhoods that up until a few months ago were protected habitat for single-family homes losing population? Obviously, the neighborhoods weren't becoming denser. I'm having a hard time finding data on the change in household size in the same year, but it stands to reason that stable households would have children age out eventually. If the parents stayed put, then theoretically, the population would decline.

Your semi-regular update on what schools have low vaccination rates around Olympia

Usually, about when there is something in the news about an outbreak around here, I'll go to the state Department of Health and find out what the vaccination rates are at our local schools (and here). This time around, there is a measles outbreak just about an hour south of us, so I thought it would be nice to narrow in specifically on exemptions (personal, religious or health) for the measles, mumps, rubella vaccination.

According to the most recent data, there are a handful of schools in the Olympia area with fairly high exemption rates for the MMR vaccine.

Here is the most recent data from the state and the spreadsheet I used.

What leaves me scratching my head about this data is that when you parse out the medical and personal exemptions, they seem to follow the same general pattern. Schools with high personal/religious exemptions also have high medical exemption rates. 

When I first started looking at this stuff, I assumed medical exemptions would be evenly dispersed across the area. It follows that since all of the schools that have high exemption rates are schools you either generally lottery into or opt into, that the personal/religious exemptions would gather there.  In the same way that opting into certain schools is an expression of a family's choice, so is opting out of vaccination. But the medical reasons for not being vaccinated, I don't think, would be more general and would not necessarily be tied to a family's school choices.

If you're new to this issue or just need some background, here is some information you might find useful:

Here is an explanation on how those exemptions work.

You've heard about herd immunity, or how the vaccination rate in a group of people that protects people who can't receive a vaccine. This is why a 16 percent exemption rate at ORLA or a 12 percent exemption rate at Lincoln are sort of scary.

According to the CDC, an immunization rate of 94 percent is necessary to prevent pertussis from persisting in a community. That is above the 88 percent that the exemption rate at Lincoln would indicate is that school's immunization rate.
