Concrete in Boulder has to do more than look level on placement day. Driveways, patios, walks, steps, and public-edge flatwork must fit the parcel, drain without creating a new nuisance, rest on support appropriate to Front Range soils, and cure through abrupt weather changes. The permit path also changes at the right-of-way line. Apollo Construction starts by separating private work from the approach, sidewalk, curb, gutter, or alley elements reviewed by City of Boulder Planning and Development Services Right-of-Way team.
This page explains the local checkpoints we use before pricing and scheduling. It is a planning guide, not a substitute for a site-specific permit decision or engineered design. We verify current requirements against the address and final scope because road ownership, recorded plats, utilities, drainage, and association covenants can change what an otherwise straightforward slab requires.
Boulder Treats Sidewalks and Curb Cuts as Right-of-Way Construction
The City of Boulder Planning and Development Services Right-of-Way team lists sidewalks, street cuts, curb cuts, curb and gutter, and street or alley paving as public-way work. A driveway project that reaches any of those elements is not merely a private slab replacement. We establish the right-of-way line and separate the private drive from the public approach in the drawings, estimate, and schedule so the correct review is completed before demolition reaches City infrastructure.
For estimating, that distinction matters. We measure the affected public and private areas separately, note who approves each portion, and identify any inspection hold point. The planning range can then reflect the known restoration area, access, forming, base work, and protection without pretending hidden soil or agency comments are already resolved.
A Boulder ROW-Licensed Contractor Must Carry the Permit
Boulder limits a right-of-way permit application to a contractor licensed for right-of-way work, and the permit must be present at the construction site. The City’s in-property utility permit has a different eligibility rule, which is another reason not to combine every exterior concrete condition under one generic permit label. Apollo Construction confirms who will hold each permit and who will request the inspection before the scope is priced as construction-ready.
Our preconstruction record includes photographs, dimensions, surface elevations, and the condition of adjacent panels. That information lets the owner see what is included and gives the permit holder a defensible starting point if the reviewer changes a limit. It also keeps a small public detail from becoming an unplanned interruption after the private work is open.
Boulder Requires a Traffic and Pedestrian Control Plan at the Public Edge
The City’s right-of-way application calls for a traffic-control plan and construction drawings or site plans showing the location, work, and easements. For concrete, pedestrian routing matters because forms, demolition debris, curing protection, and a fresh slab can block the normal path longer than the actual placement. We plan an accessible route, protect the work zone, and coordinate any managed parking or state-highway involvement identified by the City.
We treat the approved drawing and field condition as a paired check. If utilities, drainage, mature roots, or prior repairs conflict with the concept, the design returns to review before placement. Concrete is difficult to alter cleanly after cure; resolving the geometry first is faster and less costly than cutting a new slab to correct an avoidable conflict.
A Boulder Curb Restoration Can Follow a Driveway Removal
Boulder’s Parking, Landscape and Site Access Guide explains that a garage conversion or access change may require removal of a former driveway and a right-of-way permit to restore a standard curb. In other words, abandoned access is not automatically allowed to remain as a depressed curb and unused paving. When the function of a driveway changes, we verify parking compliance, landscape-setback impacts, and the required curb restoration rather than pricing only demolition behind the sidewalk.
The scope also names what remains outside the concrete contract: survey work, geotechnical design, utility relocation, association fees, or agency-directed upgrades unless expressly included. Those items can be estimated as planning allowances when their extent is not yet known, but they are never represented as a fixed quote before the responsible reviewer defines them.
Boulder Soil Conditions Are a Site Test, Not a Citywide Assumption
Boulder sits where plains deposits, creek alluvium, old fill, and foothills geology can change over short distances. The Colorado Geological Survey documents swelling clay across the Front Range, but that regional fact cannot prescribe one base section for every Boulder property. We inspect drainage and prior movement, proof the exposed subgrade, and seek geotechnical direction where the slab is structural, the fill is undocumented, or movement suggests expansive material.
At the exposed-base stage, we compare the field condition with the assumptions used for pricing. Soft pockets, buried debris, uncontrolled fill, or unexpected water are documented and addressed before the formwork is accepted. A stable, uniform support layer and controlled drainage usually contribute more to long service than hiding a poor base under additional concrete.
Boulder Concrete Protection Begins Before the Truck Is Dispatched
Freeze-thaw durability depends on an exterior mix suited to exposure, deliberate air entrainment, drainage, curing, and protection from early freezing. Boulder also expects right-of-way inspections to be requested directly through its designated team. We therefore confirm the inspection hold point, weather window, curing materials, and protection plan before dispatch. That avoids choosing between a missed inspection and concrete arriving at a site that is not approved to place it.
Pour readiness is a yes-or-no decision. The permit, inspection, access, batch, labor, finish tools, curing materials, and weather protection all have to align. If any critical item is missing, we protect the prepared site and reschedule. That discipline is especially useful on occupied homes, where an unusable driveway or walk affects daily access.
Concrete Work Near Boulder
Apollo Construction plans residential concrete as a connected site system. Typical scopes include driveway replacement, front walks, patios, stoops, utility pads, shed slabs, small equipment pads, and repairs where an adjoining remodel changes grades or access. We begin with the intended use: vehicle loading, foot traffic, outdoor living, drainage correction, or a clean transition to a garage, deck, addition, or landscape.
Site evaluation and scope
We measure the placement and the route needed to build it. Gates, overhead lines, landscaping, irrigation, public walks, street trees, neighboring property, and concrete-truck or pump access can change the method and budget. Existing cracks are read as evidence: settlement, heave, restraint, poor drainage, missing joints, or an overloaded edge each suggest a different correction. We also locate downspouts and irrigation because repeated wetting beside expansive soil can undermine an otherwise sound replacement.
Base, forms, reinforcement, and joints
After demolition, unsuitable material is removed to the limit supported by the field condition and approved design. The base is placed and compacted uniformly, forms are secured to the intended elevations, and reinforcement is positioned rather than left on the ground. Joint locations are planned around panel shape, fixed structures, thickness changes, and stress concentrations. Isolation at foundations, columns, and existing slabs is selected deliberately so movement has a place to occur.
Reinforcement helps hold cracks tight and maintain alignment; it does not make an unstable subgrade disappear. Likewise, control joints encourage cracking at planned lines but do not replace drainage or curing. We explain those roles during scope review so the owner can compare proposals by construction method, not just by the stated thickness or surface finish.
Mix, placement, finish, and cure
The concrete mix is matched to the approved specification, exposure, placement method, and finish. Exterior work needs durability through freezing, thawing, moisture, and deicing exposure. During placement, the crew consolidates edges, strikes the slab to grade, confirms drainage, and applies the selected broom, trowel, exposed, or decorative finish without overworking bleed water into the surface. The curing plan starts immediately after finishing and protects moisture and temperature while strength develops.
Planning ranges, changes, and closeout
Concrete costs are presented as planning ranges based on measured area, demolition, disposal, access, base preparation, forming complexity, reinforcement, finish, permit work, testing, and weather protection. They are estimates rather than quotes until the site condition and approvals are known. If hidden fill, a utility conflict, or an agency-directed restoration changes the work, we document the condition and its budget effect before proceeding.
Closeout includes removing forms and debris, restoring disturbed areas within scope, confirming drainage after the slab can accept water, and protecting the concrete from traffic during curing. For public work, final acceptance follows the responsible authority’s inspection. We also provide practical use and maintenance guidance: avoid premature loading, manage deicers thoughtfully, keep drainage paths open, and seal only when the chosen finish and product call for it.

Common Questions
Does a concrete driveway in Boulder need a permit?
It depends on the location and change. Private replacement in kind may follow a different path from a new or widened drive, while work at the sidewalk, approach, curb, gutter, alley, or public right-of-way is reviewed by City of Boulder Planning and Development Services Right-of-Way team. We verify the address, right-of-way, road owner, and proposed geometry before advising that no public permit is involved.
Can new concrete be poured over an old driveway or patio?
Usually that is a poor default for exterior flatwork. The old slab may already have movement, drainage, elevation, or cracking problems, and covering it reduces room at garage doors, steps, siding, and walks. We inspect the condition and transitions first. Removal exposes the support layer and allows the replacement to be graded, jointed, and isolated as a new system.
How do expansive soils change the project?
Expansive clay changes volume as moisture changes, so the response is site-specific moisture control and uniform support. We look for heave, settlement, irrigation leaks, downspout discharge, soft areas, and undocumented fill. A geotechnical professional may be needed where the consequences or observed movement warrant it. No contractor should promise that extra thickness alone eliminates soil movement.
Can concrete be placed during a Boulder winter?
Yes, when the ground is suitable, the mix and placement temperature meet the specification, and the crew can protect the fresh concrete through the vulnerable curing period. The plan may require heated materials, insulation, enclosure, or monitoring. If protection cannot be maintained or the authority restricts the work, the pour is delayed. We do not treat an unseasonably warm afternoon as the entire weather plan.
How is a concrete estimate prepared?
We use dimensions, demolition and disposal, access, base assumptions, reinforcement, joints, finish, drainage, permits, testing, and curing protection to develop a planning range. A site visit and authority review refine it. The estimate states allowances and exclusions so it is not mistaken for a final quote while subsurface conditions or public restoration limits remain unknown.
