Concrete in Evergreen, CO

Concrete in Evergreen starts with a question a Denver-metro driveway rarely raises: who actually owns the road the slab connects to. Evergreen has no town government, so a driveway, patio, or walkway here is reviewed by Jefferson County rather than a city engineering department, and the county’s rules split cleanly between the private slab on the property and any work that touches a county road or right-of-way. We sort that distinction before pricing a single yard of concrete.

Evergreen Concrete Permits Run Through Jefferson County, Not a Town Hall

Because Evergreen is an unincorporated, Census-designated community, Jefferson County Planning & Zoning and Building Safety in Golden are the reviewing bodies for any concrete work that needs a permit, and Transportation and Engineering handles road and right-of-way work specifically. There is no separate Evergreen public works office to call.

That single-county structure is convenient once you know it, but it means a homeowner cannot assume a driveway rule that applies in Lakewood or Golden transfers directly to a mountain address. We confirm the applicable process against the parcel before scheduling demolition or forming.

Driveway Access Permits and the County’s 15- and 25-Foot Rule

A new driveway, or a change to an existing one, that takes access from a county-maintained roadway requires an Access Permit from Jefferson County Planning and Zoning. A driveway built without curb and gutter that connects to a county-maintained road needs the same Access Permit.

The permit specifically covers the access cut and work on the first 15 feet of the driveway on a residential road, and the first 25 feet on an arterial road. Everything past that point is private work, but the first stretch nearest the road is treated as part of the county’s roadway system.

Right-of-Way Work Needs Its Own Permit

Work performed inside county right-of-way or an easement, which can include a curb cut, an approach tie-in, or placing a dumpster in the public right-of-way during the job, requires a separate Right-of-Way Use and Construction Permit, sometimes called a street-cut permit. Applications go to Transportation and Engineering, and the county asks for roughly 48 hours to review a submitted application.

Depending on the scope, Jefferson County can also require a job-specific bond for right-of-way work. We treat that as a planning line item rather than an afterthought, since a bond requirement discovered mid-project can stall a pour date.

Grading, Drainage, and Evergreen’s Sloped Lots

A new driveway or a larger patio that adds regrading or a meaningful amount of impervious surface can trigger Jefferson County’s land-disturbance permitting. A Notice of Intent applies to smaller, standards-compliant grading; a full Grading Permit is required whenever the work needs relief from standards, and is explicitly required once disturbance exceeds one-half acre (21,780 sq. ft.). Projects disturbing more than one acre also need a separate state Construction Site Stormwater Permit from CDPHE.

Evergreen’s mountain terrain makes this more than a paperwork exercise. Sloped lots change how water moves once a hard surface replaces bare ground, and the county’s Storm Drainage Design and Technical Criteria govern how a new concrete surface has to manage that runoff rather than shed it onto a neighbor’s property or the roadway.

Private Roads and Well and Septic Lots Change the Picture

Many Evergreen streets are not county-maintained; some are private roads or fall under a local special district. Because the county’s Access Permit specifically applies to a “county-maintained roadway,” whether that permit even governs a given driveway depends on who owns the road in front of the house, not just the fact that concrete is being poured. We confirm road ownership for the specific address before telling a homeowner whether a county Access Permit applies at all.

Well and septic service, common across Evergreen, is a separate track from the concrete work itself but often runs through the same yard. A driveway or patio project that crosses a septic line or well line needs that utility located and protected before excavation, independent of whichever county permit governs the roadway-side work.

How We Sequence an Evergreen Concrete Project

We start with the address and road ownership, then separate the scope into private slab work, any county-maintained roadway access work, and any right-of-way work, because each can carry its own permit and its own reviewer. Grading and drainage are checked against the county’s disturbance thresholds before a final layout is set, particularly on a sloped lot where cut-and-fill volume is easy to underestimate.

Once permits and utility locates are confirmed, our crew handles demolition of the old surface where applicable, base preparation suited to mountain soils and freeze-thaw cycles, forming, reinforcement, placement, and curing, with county or right-of-way inspection scheduled at whatever hold point the issued permit requires. The result is a slab that fits both the property and the specific authority that governs the road in front of it.

Common Questions

Does a new driveway in Evergreen need a Jefferson County permit?
It depends on the road. A driveway taking access from a county-maintained roadway needs an Access Permit covering the first 15 feet on a residential road or 25 feet on an arterial road. Many Evergreen roads are private, which changes whether that specific permit applies, so we confirm road ownership for the address first.

Is a separate permit needed for work at the curb or in the right-of-way?
Yes. A curb cut, approach tie-in, or any work inside county right-of-way or an easement requires a Right-of-Way Use and Construction Permit from Transportation and Engineering, which is a different application from the driveway Access Permit.

When does a concrete project need a grading permit in Evergreen?
Jefferson County requires a Grading Permit once land disturbance exceeds one-half acre, or whenever the work needs relief from the county’s standards even on a smaller lot. A Notice of Intent can apply to smaller, standards-compliant grading tied to a driveway or patio.

Why does drainage get so much attention on an Evergreen concrete job?
Evergreen’s sloped, mountain terrain means new impervious surface can change how stormwater moves across a lot far more than the same square footage would on flat ground. The county’s Storm Drainage Design and Technical Criteria govern how that runoff has to be managed as part of the project.
