A Public Improvement District Will Not Fix Niwot’s Roads

Why a townwide district unravels, and why a neighborhood one never adds up. A townwide district is affordable only while everyone stays in it — and almost everyone has either a legal reason or an arithmetic reason not to.

The Argument

Niwot has 31 miles of road. Twenty-three of them have no funded repair plan, and the average pavement condition index across those 23 miles is 44 — well below any standard a Colorado municipality holds itself to. A public improvement district is a county-created taxing unit, and it is what people mean when they ask “why not just do a PID?”

It is a fair question and it deserves an arithmetic answer.

A townwide district is affordable only while everyone stays in it, and almost everyone has either a legal reason or an arithmetic reason not to.

That is the whole finding, and it runs in a chain. Four groups have a plain case to be drawn out of any boundary, because a district would tax them for roads it never touches or roads they already pay for — and the largest of them, the business parks, can make its case by forming a district of its own. The neighborhoods left holding the bill are the ones whose roads cost the most, and at that price several of them would do better alone — so they have a reason to vote no, and each one that does gives two more the same reason.

The four sections below are that chain, one link each. Everything that used to sit in front of it — what a district is, how one is formed, the full record of the two attempts, the case for neighborhood districts, and the places our own case is weakest — is in the appendices, unchanged.

This paper starts from 18: the 2025 proposal’s own boundary, downtown out, with everyone inside paying. Other boundaries give other first rungs, depending on whether downtown and the business parks are in; none of them is a price anyone would be charged, and Appendix C keeps the record of the range we used to quote.

1. Four Groups Have a Plain Case to Be Left Out

Every townwide figure assumes that everyone inside the boundary pays. A district does not get to assume that, because its boundary is not given: the petitioners draw it and the county commissioners approve it. The 2025 proposal is the example — it left downtown out from the start, and lost neighborhoods before it was withdrawn.

Four groups have the plainest case to be drawn out, because a district would tax them for roads it never touches, or for roads they already pay for:

• The eight neighborhoods on private roads. A district cannot spend a dollar on private pavement, so it would tax 349 properties and never touch their streets.
• The 83 properties on Niwot Road, Franklin, Monarch Road, Neva, 79th and 83rd. Those are county roads; the county still maintains them, and they are not in the 23 miles a district would cost.
• Burgundy Park, which already pays a district of its own for its own roads.
• The business parks — Boulder Tech Center and Monarch Park, fifteen parcels holding nearly a quarter of the town’s taxable value. Their 1.4 miles of parkway are in the townwide program today. But they need nobody’s permission to put themselves where Burgundy Park is. The same statute lets them form a district for their own parkways: a petition needs 30% or 200 of a district’s electors, whichever is less, and a business owner votes through a designee (CRS 30-20-503(1)(a)(II), 505(1)). If every owner signs — there are about fourteen — the commissioners may waive the hearing and declare the district organized without an election (505(4), 508(4)(c)).

Downtown stays out too, as it did in the 2025 proposal: Second Avenue already pays an improvement-district tax of its own. Take those groups out, and their roads with them where a district would have paid for them, and this is what is left:

That is the least contestable townwide district there is, and it costs half as much again as the same boundary with everyone in. The parks are the largest step on their own: they carry about four times as much taxable value as road, so taking them out moves the levy four mills. A district whose price depends on its largest taxpayer staying in, when that taxpayer has an ordinary route to a district of its own, is a fragile district.

What we are not saying. Nothing has ever proposed leaving out the business parks; all fifteen parcels were inside the 2025 boundary, and none of these four groups has said it would ask to be left out. We are not predicting that any of them does. Nor is this a claim that the law removes them: the statute’s benefit test (CRS 30-20-508(2)) is applied to a district as a whole, and does not carve out individual properties — Appendix B sets it out. Whether the commissioners would approve any particular boundary is theirs to decide. This is careful statutory reading, not legal advice.

2. So the Neighborhoods Left Have a Cheaper Option

It does not stop there. At 27 mills, five neighborhoods — Monte Vista, Johnson Valley, Legend Ridge, Somerset Estates and Autumn Ridge — would pay less for a district of their own than for this one.

They cannot leave. Their own streets are inside the townwide district, so they get a general benefit, and there is no neighborhood opt-out — Appendix B sets out the statute, and the short version is that a subdivision cannot decline to be in a district that includes it. What they have is not an exit. It is a cheaper option, and therefore a reason to vote no.

If they act on it, the levy on everyone left rises to 30 mills, which gives Niwot Estates and Old Town the same reason. After that nobody else would do better alone, and the district settles at about 31 mills: the neighborhoods whose roads cost the most to fix, paying for themselves.

3. How Far That Can Be Pushed

We priced it to favour the district. A neighborhood’s own district is priced here the way the county prices one — full-depth reconstruction at $11 a square foot — which is dearer than the condition-based pricing behind the townwide figure. That makes going it alone look more expensive than it might be, so fewer neighborhoods appear to have a cheaper option. Price each neighborhood’s own roads the way the townwide figure is priced, and at 27 mills eleven of the 24 neighborhoods, 453 homes, would be paying about $1.5 million a year for about $1.1 million of their own roads — roughly $460,000 a year toward everyone else’s. On that basis the district never settles at all.

The stopping point is close, and it does not move the answer. The two neighborhoods nearest the line sit within a mill of it. Make every neighborhood’s own district 2% cheaper and both cross — and the levy then dips slightly, to 31, and holds. Whatever the exact count, it settles around 31.

Generous financing does not rescue it. Financed over 25 years, the full life of the road, rather than the 20 years our bond adviser quoted, the district that survives its objections starts near 25 mills and settles near 28 — still $1,950 a year on the median home, about two and a half times incorporation.

Why the first rung is 18 and not the 2025 proposal’s 12. The 12 was never a project estimate. Boulder County calculated it from the total cost of the roads “spread over a 25-30 year life cycle,” with no borrowing. A district cannot pay for roads that way. It borrows to do the work up front and repays with interest, and state law limits its bonds to twenty years (CRS 30-20-522(1)) — the same terms our own town budget carries its road bond on. Financed like that, the same roads need about 17 mills; priced on roads two years older, 18. A district formed now reaches a ballot in November 2027 at the earliest, and the county says work “would not likely begin until 2029.” Same roads, same condition, same 20-year terms on both sides. Appendix C has the full account.

What we are not saying. We are not predicting that any neighborhood objects, votes against a district, or forms its own, and none of the four groups in section 1 has said it would ask to be left out. We have established who has a plain case to be drawn out, who would have a reason to vote no, and what the bill looks like for everyone left. Whether any particular boundary would be approved is a question for the commissioners and their counsel, not for us.

4. And None of It Is on Offer in Any Case

2013 — defeated at the ballot. Boulder County placed a county-wide subdivision paving district on the November 2013 ballot as Issue 5C, at up to 7.15 mills. It failed.

2025 — withdrawn before the ballot. A citizen committee assembled a townwide proposal at about 12 mills. After pushback over the boundary, the organizers withdrew it. It never reached a vote.

2026 — nothing on the table. There is no proposal today and nobody assembling one. That is not an accident of timing. The 2025 organizers stopped because they concluded the instrument was wrong — a district taxes Niwot property owners to repair roads the county owns, raises the money from property tax alone, is administered from Boulder, and cannot be dissolved by the people who voted it in — and several of them joined the incorporation effort. The registered committee opposing incorporation is not proposing one either; it recommends neighborhood districts, by name and by example. A townwide district has no author on either side. Appendix C is the full record, including why we think that matters more than the two defeats.

5. What This Leaves

No public improvement district on offer fixes Niwot’s roads, and the two kinds fail for different reasons.

A townwide district is legally available — 200 signatures petitions one — and it unravels as its boundary is drawn, from 18 mills to about 27 to about 31, which is $2,160 a year on the median home against $752 for incorporation. Nobody is offering one.

A neighborhood district is the one that demonstrably works, and it does not scale. Two have formed in the county in ten years. They cost the typical household about 33 mills against incorporation’s 4 mills plus a shared sales tax, they cover only the subdivision that organized, and they leave the collector roads between neighborhoods unfunded permanently. Appendix D answers that recommendation in full, including Burgundy Park.

Incorporation is not cheaper because the pavement is cheaper. It is cheaper per household because the base is broader, and it is more durable because the authority is general. A town can levy for roads and also plow them, write a land use code, hold standing in county decisions, and — under CRS 30-20-504(2) — vote territory out of an improvement district that an individual owner could only petition to escape.

Incorporation is not cheapest on every home. A district levies property tax only, so on the lowest-value homes in Niwot the two run within a few dollars a month. Appendix E names the two neighborhoods where that is true and says what changed for them.

Appendices

The material below used to be sections 1 through 7 of this paper. It is unchanged; it is behind the argument rather than in front of it.

Appendix A. What a District Is, and What the Statute Permits

An improvement district under CRS 30-20-503(3) is

a taxing unit that may be created by any county in this state for the purpose of constructing, installing, acquiring, operating, or maintaining any public improvement or for the purpose of providing any service so long as the county that forms the district is authorized to perform such service or provide such improvement.

CRS 30-20-504(1) grants the same authority in the same words.

A district is not a capital-only body. This is worth stating plainly because we have said otherwise. Earlier versions of our own material claimed a district could not lawfully fund snow plowing. That is not supported. Operation, maintenance and service provision appear twice, in the definition and in the grant of authority, and the test is whether the county may perform the service — which, for plowing roads, it plainly may. The only carve-outs in 503(3) are solid-waste disposal facilities under 30-20-101(8)–(9) and the waste-collection services in 30-15-401(4) to (7.7). Neither reaches snow.

What is true, and is a different claim, is that no district proposed for Niwot has ever included snow. Boulder County’s improvement-district practice has been capital work — Burgundy Park was road reconstruction repaid on a county loan. A district’s levy buys what its petition asked for, and none on offer here have asked for plowing.

This paper is careful statutory reading, not legal advice. The statutory text it relies on is quoted from the official Colorado Revised Statutes 2024 printout published by the Office of Legislative Legal Services.

Appendix B. How a District Is Formed, and Why You Cannot Opt Out

The common assumption is that forming a district is difficult. The statute says otherwise, and anyone arguing against a district should know this before an opponent tells them.

The petition threshold is very low. CRS 30-20-505(1):

The petition shall be signed by not less than thirty percent or two hundred of the electors of the proposed district, whichever is less. After the filing of a petition, no signer shall be permitted to withdraw his or her name therefrom.

Niwot has about 3,598 registered voters across its 34 neighborhoods. Thirty percent would be 1,080. Two hundred is less. So 200 signatures — about 5.6% of electors — is the binding threshold, and a signer cannot take it back. Note also that “elector” under 30-20-503(1)(a) includes non-resident property owners, so the eligible pool is wider than the registered-voter roll.

The boundary requirement is minimal. CRS 30-20-505(2)(d) asks a petition for

A general description of the boundaries of the district or the territory to be included therein, with such certainty as to enable a property owner to determine whether or not his or her property is within the district.

That is the whole requirement. There is no parcel-level benefit test anywhere in Part 5.

The only benefit test is district-wide. Under 30-20-508(2) the county commissioners must dismiss a petition if the improvement “will not confer a general benefit on the district” or if its cost “would be excessive as compared with the value of the property in the district.” Both are measured on the district as a whole, and no appeal lies from a dismissal.

We note, and do not rely on, the second ground. Niwot’s road bill runs between 0.54% and 1.68% of roughly $2.10 billion of residential actual value. A commissioner could call that excessive; nothing in the record suggests one would, and we have no precedent on what the word has meant.

Findings are conclusive. Under 30-20-508(3) the commissioners’ findings on signatures and related facts are “final and conclusive on all parties in interest, whether appearing or not.” Once the organizing resolution passes, 30-20-508(5) gives thirty days to attack the organization in court, after which it stands.

So the paperwork is not the obstacle. What a petition triggers is an election, and the election is where both Niwot attempts have ended.

How you get out, and why mostly you do not

There is no neighborhood opt-out. This matters because the campaign — ours included — has said otherwise, and it is not true. Nothing in Part 5 lets a subdivision decline to be in a district that includes it.

What exists is CRS 30-20-520, and it is much narrower:

The boundaries of any district organized under the provisions of this part 5 may be changed… The owners of property proposed to be included or excluded may file with the board a petition… accompanied by a deposit of money sufficient to pay all costs of the inclusion or exclusion proceedings… If the petition is granted, the board shall adopt a resolution…

Four things follow. Exclusion is available only after the district exists. The owner seeking it pays for the proceeding. The board decides. And the statute specifies no standard at all for granting or refusing.

And under 30-20-521, leaving does not clear the debt:

All property included within or excluded from a district shall thereafter be subject to the levy of taxes for the payment of its proportionate share of any indebtedness of the district outstanding at the time of inclusion or exclusion.

A district is easier to enter than to leave. It can be voted in by a majority of those who turn out; there is no corresponding vote to take it out.

One exception, and it points somewhere interesting. CRS 30-20-504(2):

If a municipality annexes or incorporates any territory within an established district, such territory shall remain in the district unless the municipality notifies the district’s board of the municipality’s intent to exclude the territory annexed or incorporated from the district.

So incorporation does not dissolve a district automatically — but a town government may vote territory out of one, effective the following 1 January, where an individual owner may only petition and pay. Under 30-20-504(3), once all of a district’s territory is incorporated and it carries no outstanding debt, the municipality simply takes over the district’s duties.

That asymmetry is the practical point. Inside a district you have a petition and a deposit. Inside a town you have a vote.

A second route, for the business parks only: annexation. The City of Boulder’s limit runs up N 71st Street along the Tech Center’s western frontage, and the city has annexed this kind of land here before — the IBM campus (487 acres) and Gunbarrel’s commercial land (261 acres) in the 1970s, while most of the homes around them stayed in the county. Annexation would take the parks out of any Niwot district. Nothing suggests anyone intends it, and section 1 does not rely on it: a district of their own is the shorter, more ordinary route.

Appendix C. The Townwide Record, in Full

2013 — defeated at the ballot. Boulder County itself placed a county-wide subdivision paving district on the November 2013 ballot as Issue 5C: up to 7.15 mills, up to $3.3 million a year, debt authorization up to $30 million. It failed.

2025 — withdrawn before the ballot. A citizen committee assembled a townwide proposal at about 12 mills. After pushback from neighborhoods over the boundary, the organizers withdrew it. It never reached a vote. Several of those organizers are part of the incorporation effort today.

The 12 mills was never a project estimate. Boulder County Public Works told us the levy “was calculated based on total costs for 22 miles of road spread over a 25-30 year life cycle,” and that no project-specific estimates were made because there were “no discussions of specifically which roads would come first.” The pavement was surveyed in 2024, and the county’s engineer calls it “reasonable to expect deterioration to the next level of improvement project” since then. A 2027 district would start from a 2024 survey and a 2025 levy, on roads three years older.

Why our own range moved from 15–20 to 17–22. This is a correction to the figures we published, not the explanation of the 12, which follows. The treasurer’s workbook behind every townwide figure we published until October 2026 carried a timetable forward from the 2025 proposal: it charges a townwide district 21/25 of its yearly bond payment. On the 2025 proposal’s own calendar that worked. A levy collected from 2026, with construction in 2029, banks four years of payments before any are owed, and the banked money covers the shortfall across the bond’s 21 payments to the dollar. A district started now cannot do that. It reaches a ballot in November 2027 at the earliest, first collects in 2028, and the county says work “would not likely begin until 2029.” One year of collections is not four. From its first repayment year the district has to meet the whole payment, which is how every neighborhood district in this paper is already priced and how our own town budget carries its road bond. Priced that way the townwide range is 17 to 22 mills, not the 15 to 20 we published until October 2026. The roads, their condition and the 20-year financing are the same on both sides of every comparison here.

From 12 to 18, one change at a time. The 21/25 accounts for the 15 to 20 we used to publish. It does not account for the 12, which is lower still. On the county’s own budget-level unit costs (11 miles of reconstruction at $1.75 million a mile, 5.5 of mill-and-overlay at $700,000), spreading the cost evenly over 25 years with no borrowing cost, and adding maintenance and the proposal’s 5% Master Plan share, comes to 12.1 mills on the 2025 boundary; over 30 years, 11.2. That is the 12. A district cannot pay for roads that way. It borrows to do the work up front and repays with interest, and state law limits its bonds to twenty years (CRS 30-20-522(1)). Financed like that, at the same 4.62% over 20 years that prices the town’s road bond, the same roads on the same survey and the same tax base need about 17 mills. Price them on the condition expected by 2027 and it is 18, the first rung of the ladder in section 1. The tax base barely moved: $188.3 million implied by the 2025 levy, $189.1 million on today’s roll. Nothing between 12 and 18 is a change of scope.

It is worth being precise about what happened, because we have described it carelessly before. The 2025 proposal did not “fail” — it never reached a ballot to fail at. And neighborhoods did not ask to be excluded, because there is no such mechanism. What happened is that the people organizing it concluded it would not pass and stopped.

2026 — nothing on the table. There is no proposal today and nobody assembling one. This is the honest gap, and it is a stronger point than the often-repeated claim that “no organization exists to run one.” Running a district is the county’s job. The missing thing is upstream: there is no proposal for a voter to weigh against incorporation at all.

Why nobody is assembling one

The absence of a proposal usually gets read as inattention — as though a townwide district were simply an idea whose turn has not come. That is not what happened, and the real reason is more useful to a voter.

A townwide district does not organize itself. Someone has to draw a boundary, set a levy, carry a petition, survive a commissioners’ hearing and win a campaign. In a community of 4,300 people the number of groups with the appetite and the infrastructure to do that is small, and both of the ones that exist have examined this mechanism at close range and declined it — for opposite reasons.

The people who know the instrument best are the ones who put it down. The 2025 organizers were not casual and did not run out of stamina. They drew a boundary, set a levy at 12 mills, collected 237 signatures against a threshold of 200, and got as far as a public hearing before the county commissioners. What stopped them was a conclusion about the instrument itself: a district taxes Niwot property owners to repair roads the county owns, raises the money from property tax alone, is administered from Boulder rather than Niwot, and cannot be dissolved by the people who voted it in. One by one they concluded that incorporation answered the road problem and several others besides, and they joined that effort — bringing the petition experience and the road data with them. The two efforts began independently — the district group was working on roads, the incorporation group on a broader set of governance questions — and converged through the autumn of 2025 as the organizers reached that conclusion one at a time. The people best placed in this community to run a townwide district are the people who stopped running one, and said publicly why.

Why we do not simply build one instead. The fair challenge to all of this is: if the roads problem is as urgent as we say, why do the people who organised the last district not organise another one? The answer is the chain in sections 1 to 3, and Appendix E. The arithmetic that moved us is still the arithmetic — a townwide district costs the median household more than incorporation and buys pavement only, and its affordability rests on the one taxpayer with a documented cheaper way out. None of that changes because a different set of volunteers picks up the petition.

Which is worth stating plainly, because it is the honest shape of what comes next: if a townwide district comes back to Niwot, an incorporation argument comes back with it. Not necessarily from this committee — that is not a threat and we may not be the ones organising by then. It is a structural observation. The facts that make a district expensive per household belong to the mechanism, not to the people currently arguing about it, and anyone who works through the chain and Appendix E arrives where we arrived. A community that can be persuaded to tax itself 18 mills for pavement can be shown, with the same figures, that four mills and a shared sales tax buys the pavement and a town. That is why the two proposals have not managed to coexist here, and we do not expect the next attempt to go differently. We are not saying a townwide district could never pass. We are saying whoever brought one would be arguing against the arithmetic rather than against us — and the arithmetic does not improve for them with time.

We state that plainly because it cuts at us too. A reader is entitled to observe that the strongest organized force against a townwide district in Niwot is the incorporation effort, and that we are not disinterested. We are not. The answer is that we did not oppose the district from outside it — several of us organized it, and the chain in sections 1 to 3 and Appendix E are the arithmetic we worked through on the way to changing our minds. Those sections are checkable. Disagree with them and the conclusion is fair game.

The organized opposition to incorporation is not assembling one either. Neighbors for Niwot, the registered issue committee opposing incorporation, publishes its alternative on its website, and it is not a townwide district:

Public Improvement Districts (PIDs), such as the one created by Burgundy Park, are a more effective way for neighborhoods to care for their roads to their satisfaction. The PID approach targets the actual problem directly.

That is a neighborhood district, recommended by name and by example. Appendix D takes the recommendation seriously and answers it there, because it deserves an arithmetic answer rather than a rhetorical one. For the purposes of this section the point is narrower: the only organized body in Niwot arguing against incorporation is arguing for the other kind of district, not this one. Nobody at all is proposing a townwide district.

What the record supports, and what it does not. Two attempts in thirteen years, one defeated by voters and one abandoned by its own organizers, is evidence that a townwide district is hard to pass in this community. It is not evidence that it is impossible, and this paper does not claim that. The defensible statement is that nobody has managed it, twice, nobody is trying now, and the people who would have to try have explained why they are not — and that a low petition threshold has never been the binding constraint.

Appendix D. Neighborhood Districts: Formable, Expensive, and Partial

The county’s own guidance points a neighborhood that wants to act alone toward its own district, and Boulder County has set up the mechanism and will help with the process. This is the version of a PID that demonstrably works.

It is also the version almost nobody uses. In ten years, two have formed in the county: Homestead in Gunbarrel, and Burgundy Park here in Niwot. Forming one requires a sustained volunteer effort, a petition, a boundary, a cost estimate and an election, carried by residents who are not being paid to do it.

And it is much more expensive per household. Across 24 costed districts covering 1,115 homes:

The typical figure is weighted by homes rather than by district, because a 21-home district should not count as much as a 140-home one. The range is real and it is wide: what you pay depends almost entirely on how much pavement your neighborhood has per home.

The Burgundy Park recommendation

This is the specific form the argument takes in Niwot, so it deserves a direct answer. Neighbors for Niwot’s website answers the claim “incorporation will fix our roads” under a heading of “Myths vs. Reality,” and its answer recommends a named example:

Public Improvement Districts (PIDs), such as the one created by Burgundy Park, are a more effective way for neighborhoods to care for their roads to their satisfaction.

Burgundy Park is a real district and it did work. It is also the most favourable case in the county, and four of the things that made it work are not available to anyone else.

It was subsidised, and that subsidy cannot be planned on. Burgundy Park was built with a 30% county contribution toward the initial project and interest-free county financing. Boulder County’s own program page now says the financial assistance “has been put on an indefinite hold” because of “uncertainty in both federal and local funding sources.” In May 2026 the commissioners supported a 30% contribution again, capped at $750,000 a year and only for two years, and two districts are already expected to use it in 2027 and 2028. Interest-free financing is not part of that; it would be a separate decision after a district forms. Asked how a new district should plan, the county’s Capital Improvements Principal Engineer told us: “I would recommend proceeding based on a conservative assumption that county funding will not be available.” Burgundy Park’s levy came in at 16.597 mills, reduced to 12.25 by a temporary credit. A neighborhood district formed now, without those two supports, runs 14 to 47 mills and typically 33 — two to three times what the example cost.

It is small, and it does not scale by repetition. Burgundy Park is 43 homes on about six tenths of a mile of road. Niwot has 31 miles across 34 neighborhoods. Reproducing its result community-wide does not mean doing what Burgundy Park did; it means doing it thirty-four times over — thirty-four petitions, boundaries, cost estimates, volunteer committees and elections, carried by residents who are not paid to do it, in neighborhoods that have mostly never had to maintain a street. Eleven of Niwot’s 34 neighborhoods have any private road at all; the other 23 — 975 homes, three fifths of the community — have none. The recommendation is not “do what Burgundy Park did.” It is “do it thirty-four times, without the subsidy, starting from scratch.”

It is the outcome, not the offer. This is the point the two-in-ten-years figure above is actually making. The mechanism was continuously available that whole decade, to every subdivision in the county, with the county willing to help set one up — while 89% of Niwot’s neighborhood road area sat as public road the county owns and does not repair. A good offer, left on the table that long, in front of a problem that large, does not produce two takers.

And its own advocates’ roads experts say so. In June 2026, at a session the Niwot Community Association facilitated, two members of the Neighbors for Niwot steering committee — the people that committee designates as its roads experts — worked through road costs with this committee and agreed there that neighborhood districts are a slow and expensive way to repair a road network. We think they were right. This section is our arithmetic for the same conclusion.

We are not saying Burgundy Park was a mistake. Forty-three households solved their own street and they were correct to take the subsidy while it was on the table. We are saying that pointing at it in 2026 recommends a deal nobody can plan on to neighborhoods that mostly cannot organise to accept it.

The deeper problem is not the price. It is that it never adds up. A neighborhood district fixes the streets inside one subdivision. It does not touch the collector roads that carry everyone, and it does nothing at all for any neighborhood that did not organize. Run the neighborhood path to its conclusion and Niwot has a patchwork: some subdivisions repaired at two to eight times the per-household cost of incorporation, the connecting roads still unfunded, and no mechanism that ever covers the whole town.

That conclusion does not rest on any single figure, which is why we lead with it.

“We’ll fix our own street”

A third idea comes up often: skip the district, take up a collection, and repave the street ourselves. It comes from watching HOAs repair their private roads. Most Niwot streets are not private, and on a public road it does not work the way people expect.

Boulder County Public Works told us an HOA or private group “could independently fund surface reconstruction, but because the work would be done on public roads it would require a construction permit from the county.” The residents pay for the engineering, and “the county would not permit sub-standard work. The work would need to meet the same standards as work by a district.”

It is one project, not a program. “The self-funding option would not provide for future resurfacing needs (e.g. mill & overlays). Those would be unfunded and subject to future decisions by the residents.”

It cannot be the cheap fix. “If a road has deteriorated to a point where a mill and overlay would not be an effective resurfacing technique, then the county would not likely approve a permit for such work.” The county’s planning threshold for full reconstruction is a condition index below 50. The average across Niwot’s 23 unfunded miles is 44.

Nobody has done it. “I have spoken with a number of residents about the self-funding option, but none have chosen that route since I started with Boulder County.”

Appendix E. The Two Neighborhoods That No Longer Come Out Even

Until this revision we published that in two of Niwot’s neighborhoods — Cottonwood Park Condos and Cottonwood Park West — a townwide district and incorporation cost about the same. We published it rather than leave it out. On current figures that is no longer true of one of them, and it is barely true of the other, so we are saying so in the same place.

Priced like for like, at the bottom of the townwide range:

Two things moved, and most of the change is not this revision. The neighborhood incorporation figures moved to the spending basis the rest of the site uses in September, which on its own makes Cottonwood Park West about $130 a year cheaper under incorporation even at the old 15 mills. The rest is the townwide range moving from 15 to 17 mills, explained in Appendix C. Neither change was made to produce this result, and the second one would have been made if it had run the other way.

The condominiums are still a tie. Incorporation now prices about $33 a year lower, on a bill of $336. That is a tenth of the bill, on a comparison whose driving input — how many people a multifamily household holds — carries a 45% margin at 90% confidence. Our own model’s verdict is that the question “cannot be decided with available evidence.” We are not going to describe a gap that size as a win. Incorporation is not the cheapest option for every home: a district levies property tax only, so on the lowest-value homes in Niwot the two run close, and they always will.

Like for like means counting snow. A roads-only district and a town are not buying the same thing. The town’s budget carries snow removal, street sweeping, signs and striping; a district’s levy buys what its petition asked for. Set a district that bought only pavement against a town that also plows and you are comparing different baskets — the smaller one rings up lower, which tells you nothing about value. The statute permits a district to fund those services, as Appendix A sets out, so the honest comparison prices both sides for the same work. That is what the table above does.

And neither neighborhood would be in a district that survives its objections. Cottonwood Park Condos is on a private road. A townwide district would tax it and never touch its pavement, and the association would keep its own road bill either way. That is a stronger point than the price, and it does not depend on the margin.

This is the calculation that prompted the study. Two neighborhoods where the arithmetic ran close is exactly where we should be most careful, and the question was whether we owed those households the news. Checking it is how we came to the rest of this paper. A townwide district is not something either neighborhood can choose: no proposal exists, nobody is assembling one, and the two attempts ended at a ballot box in 2013 and in a withdrawal in 2025.

Appendix F. What Would Change This Conclusion

We would revise this paper if any of the following turned out to be true:

• A townwide proposal is actually assembled and reaches a ballot, which would move the record from two attempts to three.
• The Boulder Tech Center’s owners state publicly that they intend to remain inside a district boundary.
• Boulder County commits district funding beyond 2028 that is not already spoken for.
• The county indicates it would approve a boundary that keeps one of the four groups in section 1 inside — private-road neighborhoods, Burgundy Park, homes on county roads, or the business parks after forming their own district — which would lower the 27 mills toward 18 for that group’s share.
• Boulder County shares its pavement deterioration curve and it runs slower than the two points a year both our models use, or a district’s construction is scheduled before 2029.
• A bond adviser quotes 25-year financing for a county district on comparable terms, which would move the 27 and 31 toward 25 and 28.
• A survey of private-road pavement lands, which would let us price the eight neighborhoods currently excluded from the comparison for want of data.
