Owners pay for the rest, usually through a district they vote in, so on most county-side Gunbarrel parcels the road is already a tax-bill line or a cost no district has been voted to cover. - Author: Daniel Hsieh - Tags: Answer Brief, Gunbarrel, Buying, Colorado Law Boulder County plows the subdivision streets it maintains in its unincorporated areas, patches the potholes and seals the cracks. Apart from a short list of Community Use Roads, it doesn't resurface them. When the pavement on one of those streets wears out, the people it serves pay for the new road, usually through a property-tax district they vote to create. If you're buying on an unincorporated Gunbarrel street, that usually leaves the road in one of two conditions. A district already exists and its levy is a line on the parcel's tax bill, or no district exists yet and the cost of the next repaving is still sitting in the asphalt, unvoted. > **The short answer:** In unincorporated Boulder County, the county plows and patches the subdivision streets it maintains, but full resurfacing is paid for by the owners those streets serve. They usually fund it through a **Public Improvement District** that voters inside it approve, which then adds its own levy to the property tax bills inside its boundary. The county's page says it currently matches **30% of the cost, up to $750,000 a year**, and it repaves a short list of **Community Use Roads** itself. So on most county-side parcels the road is either already a district line on the tax bill or a cost no district has been voted to cover. ## Who pays for subdivision road paving in unincorporated Boulder County? **The owners the street serves, under the county's comprehensive plan.** The plan aims the county's major-repair money at arterial and collector roads and says that funding major repairs of "local access roadways," which it also calls subdivision roads, "shall be the responsibility of those served by the road." Public Works says it is "unable to undertake large roadway repaving projects" inside subdivisions for that reason. Its crews still plow, patch potholes, clear ditches and culverts, repair sidewalks and seal cracks on those streets. The line falls at full resurfacing. The route the county points owners to is a [Public Improvement District](https://bouldercounty.gov/transportation/subdivision-paving/subdivision-paving-pid/?ref=truenorthboulder.com), formed under C.R.S. 30-20-501 and the sections that follow. Once voters inside it approve, a district can take on debt and levy a property tax on the real and personal property inside its boundary. The county's page says the commissioners are "currently offering a 30% match, up to $750,000 per year." In Gunbarrel's Homestead subdivision, which voted its district in on November 5, 2024, the county is funding all of the initial construction, and the district repays 70 percent of that cost through its tax over what the county estimates at about eight years. The match is the commissioners' to offer each year, so confirm it with Public Works for the year that matters to you. One exception changes who pays, and one changes how the owners pay. The county rehabilitates about 25 miles of subdivision streets it calls Community Use Roads, the ones that carry people to trailheads, schools and places of worship, and its list of repaired roads includes Heatherwood Drive and Twin Lakes Road. And a homeowners association can collect the money itself instead of forming a district, with the county estimating, designing and bidding the job and inspecting the work. A lot the City of Boulder has annexed is outside the county program; [the Gunbarrel guide](https://truenorthboulder.com/boulder/gunbarrel/) explains why that line runs lot by lot there. Nor is a road district a metro district. A new-build metro district is usually formed by the developer, with its debt authorized when it's formed, and [what a metro-district mill cap really means](https://truenorthboulder.com/guides/what-a-metro-district-mill-cap-really-means/) covers that kind. A road district is voted onto an older subdivision by the people already living in it, and it may not exist yet when you buy. Some subdivision roads were never accepted for county maintenance. On those, the owners or the HOA carry plowing and repairs as well, sometimes under a recorded road agreement, which would appear as an exception on the title commitment. Start by asking Public Works (303-441-3900, [tdadmin@bouldercounty.gov](mailto:tdadmin@bouldercounty.gov)) whether the street is county-maintained. __Where a county subdivision street can stand, who pays for its next resurfacing, and where a buyer can see it. Unincorporated Boulder County only; confirm any street with Boulder County Public Works.__ | The street | Who pays to resurface it | Where you'd see it | | -------------------------------- | -------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------- | | Inside a formed road district | The district's levy on the property inside it, plus the county's share; an ongoing levy, not a payoff | A district line in the parcel's tax area, on the Assessor's levy tables and the tax bill | | In a district proposed this year | No one yet; if voters approve in November, the first tax bills carrying it arrive the next calendar year | A request or petition on file with Public Works, a commissioners' hearing, the November ballot | | No district, no petition | No one yet; the cost waits until owners form a district or an HOA collects the money | Not on the parcel's tax records; ask Public Works for the street's pavement rating | | A Community Use Road | The county, as funding allows | The county's Community Use Roads list, or Public Works | ## Before there's a district: the vote you'd inherit **A street with no district has no levy, so the cost of its next resurfacing shows up on no tax record.** It isn't on the levy tables or the tax bill. It's in the pavement. Every three years an outside company the county hires measures the pavement on every paved road countywide, and the county reports that "a majority of paved roads in county subdivisions are in 'poor' condition." Ask Public Works for the street's rating from that survey; the county says it has made a subdivision pavement-quality map from it. A cost estimate is yours for the asking: the county's FAQ says its transportation staff "will provide estimates on costs for resurfacing operations"; ask for it before you write the offer. The estimate it prepares for owners weighing a district covers more than one job: reconstruction, a mill and overlay about every 20 years, chip seal about every 7, and a preliminary mill levy. A district funds a cycle of work, not a single repaving. If the street gets a district after you own the house, its terms come from the ballot question: the most it may levy, the most it may borrow, and the boundary it covers. The tax is first collected at the beginning of the calendar year after the vote. The Assessor's 2025 levy table names two road districts, against 145 miles of paved road in 115 county subdivisions. Most of those streets have no district, and some may never get one. The pavement keeps aging either way. On a street like that, a lower tax bill doesn't mean a cheaper road. What to budget for is the chance of a levy you and your neighbors may one day vote onto that bill. If the subdivision has an HOA, the association documents you receive once you're under contract can include recent minutes and any reserve study; read whether they mention the roads. ## How does a road district get onto the Boulder County ballot? **It starts with the neighbors, and from the petition on, the steps happen in public.** Owners ask Public Works to assess their roads and map a proposed district, and the county prepares a preliminary cost estimate and mill levy. If they want to go ahead, they send Public Works a formal letter; the county suggests starting by the end of February. A petition then circulates. It's due at the county by the end of June, signed by at least 30 percent or 200 of the electors in the proposed district, whichever is less. The commissioners schedule a hearing 20 to 40 days after it's submitted, the ballot is final at the end of August, and the district is decided at the November election. That sequence gives a buyer something to check between spring and fall. Ask Public Works whether the subdivision has requested an assessment, sent a letter or filed a petition this year, and whether a hearing is scheduled. Two more proposed road districts in unincorporated Boulder County are on the November 3, 2026 ballot. The seller may already know. A petition circulates door to door, so ask in writing whether they've signed or been asked to sign a road-district petition, or received county notice of a hearing. If you're the one selling on a county-side street, a buyer's agent is likely to ask the same questions. Whether a pending road district belongs on your [Seller's Property Disclosure](https://truenorthboulder.com/guides/colorado-seller-property-disclosure/) is your decision on that form; take it to your broker before you list. If you close between a November vote and the January tax bill, the contract's tax proration may be figured on a levy that doesn't yet include the district, even though the district's first levy may cover the year you closed in. [How taxes are prorated](https://truenorthboulder.com/guides/seller-net-proceeds-colorado/) is a choice made in the contract. Ask your broker and the title company how a newly approved levy is handled at your closing. ## Is a Boulder County house already paying for its street? **Check the parcel's tax area: a road district is listed there by name, with its own mill rate, on the Boulder County Assessor's levy tables.** Look the parcel up in the county's [Property Search](https://maps.bouldercounty.org/boco/PropertySearch/?ref=truenorthboulder.com) and note the Tax Area on its Assessment tab. The Assessor's [mill-levy tables](https://bouldercounty.gov/property-and-land/assessor/assessment/mill-levies-taxing-districts/?ref=truenorthboulder.com) list every taxing authority in a tax area, each with its own rate, read the same way as [a new build's district lines](https://truenorthboulder.com/guides/why-does-this-new-house-have-higher-taxes/). On many Gunbarrel parcels the list also includes the Gunbarrel Improvement District, a separate authority the Assessor's 2024 and 2025 tables show at 0 mills. Homestead's road district appears there by name, levying 23.61 mills in levy years 2024 and 2025, the most its ballot question allowed. That question, approved in 2024, also capped the district's multi-year obligation at $1,113,141.40 and stated no end date. The county's page says that once the district has repaid its 70 percent, the money it keeps collecting goes to future resurfacing. A district's mills apply to the parcel's assessed value, not its price; ask the listing broker for last year's tax bill. Once you're under contract, the certificate of taxes due lists the same authorities, though only the ones that already exist, never a pending petition. If a line on it is new to you, [the tax certificate deadline](https://truenorthboulder.com/guides/colorado-tax-certificate-termination/) is the clock you're on. [We'll read the tax area for a county-side street and ask Public Works where its paving stands](https://truenorthboulder.com/contact/), whether that's a district already on the bill or a vote that could bring one. Common questions ## Frequently asked Who pays to repave subdivision roads in unincorporated Boulder County?+ The owners the road serves. Boulder County's comprehensive plan makes major repairs of subdivision roads the responsibility of those served by the road, so the county doesn't resurface them, though it still maintains the ones it has accepted. Owners usually pay through a Public Improvement District they vote to form, which adds its own property-tax levy to the parcels inside it, and the county's page says it currently matches 30% of the cost, up to $750,000 a year. The county does repave a listed set of Community Use Roads itself. What is a Public Improvement District for roads in Boulder County?+ It's a district formed under C.R.S. 30-20-501 and the sections that follow. Electors in the subdivision petition the county, and the electors inside the proposed boundary decide at a November election. Once approved, the district can take on debt and levy a property-tax mill on the property within it, with the tax first collected the next calendar year. The Homestead district in Gunbarrel, approved in November 2024, levied 23.61 mills in levy years 2024 and 2025, the most its ballot question allowed. How can I tell if a Boulder County house is already in a road district?+ Look the parcel up in the county's Property Search and note the Tax Area on its Assessment tab. The Assessor's mill-levy tables list every taxing authority in a tax area with its own rate, and a road district appears there by name. On many Gunbarrel parcels the tax area also shows the Gunbarrel Improvement District, which the Assessor's 2024 and 2025 tables carry at 0 mills. If there's no district on the list, ask Boulder County Public Works whether the subdivision has asked about forming one or filed a petition this year. Does Boulder County still maintain subdivision roads?+ Yes, short of resurfacing. On subdivision roads it has accepted for maintenance, the county's crews still plow snow, patch potholes, clear ditches and culverts, repair sidewalks and seal cracks. Full resurfacing falls to the owners, except on the roads the county has designated Community Use Roads. Can a road district be added to a Boulder County house after I buy it?+ Yes. Electors in a subdivision can petition to form a Public Improvement District, and if the electors inside its proposed boundary approve it at a November election, it levies on the real and personal property inside that boundary, with the tax first collected the following calendar year. So a county-side street with no district carries no road line on its tax bill today, but its next resurfacing is still unpaid, and a later vote can put it on the bill.
