Sterling Ranch Flatwork Starts with the Grading Already on Record
Concrete is the part of a yard you cannot nudge later. Each lot's drainage pattern is fixed in a recorded declaration by reference to the overlot grading plan Douglas County approved for it, and the duty to maintain that pattern sits with the owner - so a patio, walk, or driveway gets located and pitched well before anyone picks a finish.
Tell us which surface you want built and what the ground around it does with water today.
Placement before finish
Most flatwork conversations open with a finish and a color chip. Here the more useful opening is a document. Recorded on 28 September 2015, the declaration governing this community defines a lot's Established Drainage Pattern as the pattern shown on the overlot grading plan the county approved for that lot, and obliges the owner to maintain it. A poured surface is permanent, it redirects water by its nature, and it is therefore one of the easiest ways to change a pattern somebody has agreed to keep.
None of that makes a patio difficult. It moves one decision earlier: the footprint, the elevations, and the direction of fall are worked out first, and the surface treatment is chosen once they hold. Requirements also differ by village, filing, builder product, and lot condition, so what applies to a specific property is confirmed for that address rather than inherited from the community as a whole.
The recorded declaration defines a lot's Established Drainage Pattern by reference to the overlot grading plan Douglas County approved for that lot. That document, not a preference about where a patio would look best, is where a placement conversation usefully starts.
The same instrument, recorded 28 September 2015, places the duty to maintain that pattern on the owner, and provides that altering it carries consequences for the owner rather than for the parties the pattern benefits. Flatwork is one of the easiest ways to alter it by accident.
A slab does not only shed water off its own surface; it changes what the ground beside it receives. We work out the discharge edge, the receiving grade, and what happens at doors and thresholds before the footprint is treated as final.
Easements, utility routes, and any retention or detention area near the property are located for the address. The recorded declaration discloses that such areas may sit within or near a property and that surface water may accumulate - a disclosure about the instrument, never a statement about a particular lot.
Name the body, not the community
Sterling Ranch is a master-planned community in unincorporated Douglas County, governed through metropolitan districts and a Community Authority Board. For a concrete project that structure matters in a practical way: two different bodies look at the work, they are not asking the same thing, and satisfying one does not satisfy the other.
The Design Review Committee
Douglas County
Both tracks move: the board amends its guidelines and directs residents to the most current document, and county requirements are confirmed for the project at hand. We prepare what a submittal needs and put both steps in the schedule, but the decisions belong to the reviewing bodies and we do not speak for them.
Once the fall across a patio is fixed, the rest of the geometry follows it: the landing sits where the finished elevation puts it, the risers between levels are sized evenly rather than fudged at the end, and the surface texture is chosen for a slab that will be walked on wet, snowy, and frozen. Deciding the elevations first is what keeps a broad patio from collecting water at the door it was built to serve.
Side yards are narrow, and they are frequently the channel a lot uses to move water from back to front. A walk placed there without reading that flow becomes a small dam. We set the route, width, and cross-slope so the walk sheds to the side the ground already drains toward, and we keep clear of the easements and utility routes located for the address before anything is formed.
A driveway is the one flatwork surface that carries vehicles, faces the street, and sits over whatever services were trenched in before the house was finished. Before a replacement or a new pour is priced, we locate what runs underneath, look at how the approach meets the right of way, and settle the joint layout across the full width so the panels are sized for the loads rather than for the leftover geometry at the end of the pour.
The part nobody photographs
Everything above is about deciding where a surface belongs. This is about building the one that was decided on. The construction standards themselves are the same wherever we pour; what changes from lot to lot is the ground they are applied to, the access the crew has, and the week the work happens in.
Excavation starts by taking out material the site cannot support, after which the subgrade and road base are compacted and the work is formed. Support under a slab does more for its service life than anything applied to the top of it.
The documented specification is a 4500 PSI mix with fiber, plus supported 3/8-inch fiberglass rebar on chairs where that reinforcement system applies to the application. Naming a specification is not the same as promising an outcome, and each application still gets its own review before the plan is final.
Control joints are laid out against the actual shape of the pour and the way the surface will be used, so the panel sizes are deliberate rather than whatever the geometry left over. On a decorative finish the joints are planned inside the pattern instead of cutting across it.
Placement gets booked around the conditions of the week rather than a season on the calendar, the chosen finish is applied while the surface is workable, and the young slab is protected while it cures. Open, windy ground pulls moisture out of fresh concrete faster, and the plan responds to that.
The Sterling Ranch Community Authority Board's Water Demand Management Initiatives, adopted 26 August 2020, provide that a rear yard will not be approved as hardscape alone and set a minimum share of the rear yard that must stay live plant material. That makes slab size a design input rather than an afterthought: the patio is drawn at the size the space genuinely needs, and the planted area is drawn with it, not around whatever concrete is left. Which figures and conditions apply to a particular rear yard are confirmed against the current version of the guidelines for that address.
A disclosure is not a survey
Owners occasionally arrive at an estimate holding a passage from the recorded declaration, and it rewards careful reading rather than repetition. It discloses that a lot may sit on land affected by soil amendment, including expansive soils corrections, and it lists expansive soils conditions and drainage issues among the risks an owner assumes. That is language allocating risk in a recorded instrument.
It is not, however, a report on the ground under any particular home. It measures nothing, tests nothing, and describes no individual property, and we will not turn it into a claim about local soil. What sits below a proposed slab stays a site question: we look at the project area during the estimate, and where a scope genuinely calls for testing or an engineered design, that gets priced as part of the work rather than assumed away.
The same discipline applies to everything else on this page. Where a rule exists we name the body that made it and the date it was recorded or adopted; where a figure has not been verified we leave it out; and where an answer depends on the property, it gets confirmed for that address before anyone commits to a plan.
Placement is the first question rather than the last one. Each lot's Established Drainage Pattern is fixed in the recorded declaration by the overlot grading plan Douglas County approved for that lot, and the duty to maintain it falls to the owner. So the useful starting point is the grading already on file for the address, read alongside the easements, utility routes, and physical conditions found on site. What any particular lot's pattern is gets confirmed for the property before a footprint is drawn, and is not something we would state from here.
Two separate bodies asking two different questions. The recorded declaration names patios, walkways, and driveways among the Improvements needing the Design Review Committee's prior written approval before construction begins, with review in stages, a required final submittal, and resubmittal of any change to an approved plan. Separately, that same instrument provides that the committee does not review whether a proposal complies with applicable law, and that the owner is responsible for obtaining every governmental approval and permit. We prepare the submittal material and build both steps into the schedule. The decisions and their timing belong to the reviewing bodies, and we do not predict either.
Douglas County is the building, plumbing, grading, and drainage authority here, and community application material notes that additional standards may be imposed by the county or the state. What a specific scope of flatwork requires is confirmed with the county for that project before it is scheduled, rather than assumed from a figure quoted somewhere else. It is also worth separating the two tracks: design-review approval and a county permit answer different questions, and neither one stands in for the other.
No, and that is a community rule rather than a design opinion. The Community Authority Board's Water Demand Management Initiatives, adopted 26 August 2020, provide that a rear yard will not be approved as hardscape alone, and set a minimum share of the rear yard that has to stay live plant material. In practice the paved area and the planted area are drawn together rather than one after the other. The board may amend its guidelines, so what applies to a given rear yard, including its current planted coverage, is confirmed for the address.
It does not. That passage is a disclosure and an assumption of risk written into a recorded instrument: it puts owners on notice about conditions that may be present, soil amendment and drainage issues among them, and it deliberately reports nothing about any individual lot. What sits under a proposed slab is a site question. It is answered by looking at the project area during the estimate and, where the scope genuinely calls for it, by the testing or engineering that scope needs.
The grading and drainage already on record for the lot; the easements and utility routes crossing it; whether it backs to open space or sits on a corner; which village and filing it is in and which builder product it came from, since documented differences exist between them; the rear yard's current planted coverage; and the current version of each guideline, because the board updates them and residents are directed to the most current document. Nothing on that list gets inferred from the community as a whole.
Book an on-site estimate for a patio, walkway, steps, or driveway. We will look at the grading and drainage on record for the lot, the easements and access, what the surface has to do, and what each reviewing body will want to see.
