Killeen Elite Concrete works as a concrete contractor in Nolanville, TX, and this is one of the few places we work where most of the concrete going in is brand new rather than replacing something that failed. Of 2,833 housing units, 2,091 were built in 2000 or later, which is 73.8 percent, and 1,075 of them date from 2010 or later.
That changes what a concrete contractor is actually asked to do here. Instead of tearing out tired 1970s driveways, the work is builder flatwork on new lots, pads for manufactured homes, and the sidewalks a certificate of occupancy depends on. The rules that govern those three things are the ones worth knowing before quoting anything.
There is a second thing to know before starting, and it costs money to learn late. The city licenses contractors directly, permit fees double where work begins before a permit has been obtained, and on new subdivision work the pavement section has to be engineered from a geotechnical analysis rather than assumed. We work inside all of that rather than around it.
What the Ground Is Doing Here
San Saba Is the Largest Single Unit
The largest single soil map unit in and around the city is San Saba clay on 1 to 3 percent slopes, at 13.5 percent of the mapped area. It is a fine, smectitic, thermic Leptic Udic Haplusterts running a plasticity index of 40 in the surface horizon and 38 below, with 50 percent clay and a linear extensibility of 10 percent.
What makes it a different design problem from a deep clay profile is that it terminates on limestone bedrock at about 76 centimeters, roughly 30 inches. It is strongly expansive but the expansive column is shallow, so the slab is spanning a thinner layer of moving material than the plasticity index alone would suggest.
Around Forty Percent of the Area Is Shallow to Rock or Pan
Roughly 40 percent of the mapped area has a restrictive layer within about 27 inches. Brackett loam accounts for 11.5 percent with weathered limestone at about 16 inches, Purves silty clay 11.1 percent with hard limestone at about 14 inches, and Evant silty clay 8.5 percent with an indurated petrocalcic caliche horizon beginning at about 19 inches.
On those units the cost driver is breaking material rather than hauling it, which is a different conversation from the one most homeowners expect. Brackett is also the exception to the expansive story, running a plasticity index of only 11 to 13 with linear extensibility of 1.8 to 2.0 percent, below the IRC threshold entirely.
Runoff Rather Than Infiltration
Nearly every dominant soil here sits in hydrologic soil group D, including San Saba, Purves, Evant, Brackett and Branyon, with Lewisville, Denton and Frio in group C. In practical terms that means water runs off rather than soaking in, and a driveway, patio or parking area has to be built to shed it.
The Nolan Creek bottom inside the city is mapped as Frio silty clay across 7.3 percent of the area, split between an occasionally flooded and a frequently flooded phase, with a plasticity index of 34 to 36 in deep alluvium. Flatwork there sits on saturating ground and falls under the city’s Flood Damage Prevention article.

A Young Town, and What That Means for Concrete
Almost Nothing Here Is Old Enough to Replace
Only 317 units, 11.2 percent, were built before 1980, and the American Community Survey estimate for units built in 1959 or earlier is zero. There is essentially no aging flatwork cohort in this city of the kind that keeps a repair crew busy in an older town.
The consequence is that the work skews heavily toward first pours: driveways, approaches, walks, patios and pads that have never existed before. It also means the failures we do see tend to be workmanship or subgrade problems on relatively new concrete rather than the end of a long service life.
Ownership and the Detached Stock
Of 2,694 occupied units, 1,732 are owner-occupied and 962 renter-occupied, a 64.3 percent ownership rate, and 1,465 owner-occupied units are single-family detached. That is 54.4 percent of occupied units in the category most likely to call a concrete contractor directly rather than through a manager.
The city itself is small and compact, incorporated on March 27, 1961 with a total area of 3.5 square miles and a 2020 census population of 5,917. The economic development material cites a median age of 29 years, which fits a town whose housing stock is overwhelmingly this century’s.
The Builder’s Sidewalk Obligation
Both Sides of the Street, Before the Certificate of Occupancy
Sidewalks are required on both sides of the street within the affected subdivision or lots, and the builder or owner must construct the sidewalk in the right-of-way adjacent to the lot, whether it falls on the front, side or rear. That has to be done before a certificate of occupancy is issued.
Corner and through lots are where this catches people out, because a side or rear frontage carries the same obligation as the front. Scheduling that pour against a closing date rather than after it is the difference between a smooth handover and a house nobody can move into.
The Street Section It Sits Beside
A residential street carries 50 feet of right-of-way, or 60 feet where conditions are met to exempt curb and gutter, with paving width of 31 feet back-of-curb to back-of-curb. All street wearing surfaces must be concrete or hot-mixed asphaltic concrete laid over a base course.
Those dimensions set where a walk lands and how a driveway approach has to transition into it. Getting the geometry right at the outset is far cheaper than discovering at inspection that an approach meets the curb at the wrong point.
Engineered Pavement and a Regional Specification
Section 3(i) of the subdivision ordinance requires the pavement section to be designed by a professional engineer on the basis of a geotechnical analysis performed by a qualified geotechnical professional. That is not a formality on ground where plasticity index runs from 11 to 40 across a few streets.
The same section adopts the North Central Texas Council of Governments Public Works Standard Specifications and Standard Drawings, latest edition, as the construction standard. A Central Texas town running on the North Central Texas regional spec is worth checking before anyone submits details drawn up for another city.
Pads, Hard Surfaces and Manufactured Homes
Nearly a Quarter of the Stock Is Manufactured
Mobile and manufactured homes account for 676 of 2,833 housing units, 23.9 percent of the total, against 1,800 single-unit detached. That is a substantial share of the town, and it brings its own set of flatwork rules that do not apply to a conventional subdivision lot.
Those homes need pads, parking surfaces, steps and walks like any other dwelling, and the surfaces under and around them are specified by the city rather than left to preference. Knowing the specification before pricing is what keeps a job from being rebuilt.
Caliche Alone Will Not Pass
Section 3.06.002 defines a hard surface in a mobile home park as one that will not soften when exposed to moisture and is of sufficient thickness to withstand unusual wheel loads, and it states plainly that caliche used by itself is not acceptable. That single sentence rules out the cheapest option people reach for.
Where gravel or crushed rock is used, it must be applied 6 to 8 inches thick with a soil binder, or 2 to 3 inches thick over a minimum 6-inch caliche base. Those are specified thicknesses rather than guidance, and a surface built thinner is a surface that will need doing again.
Precast Slabs Have Their Own Conditions
Precast concrete slabs are acceptable only where they are at least 2 feet square, adequately reinforced, and specified in construction plans approved by the building official. All three conditions have to be met rather than any one of them.
In practice, a poured slab is often the simpler route once those requirements are counted, and it gives a single monolithic surface rather than units that can settle independently. We price both honestly and let the specification rather than the sales pitch decide it.
Licensing, Permits and the Mix the City Specifies
A General Construction License In Lieu of a Bond
Section 3.03.002(a) requires a general construction license from the city before any person, firm or corporation performs or contracts to perform a construction operation inside the city limits for which a permit is required. The ordinance states the license is issued in lieu of requiring a surety bond from the contractor.
That trade-off is worth understanding before bidding here. The license costs 100 dollars per year under fee schedule section A5.003, runs on a calendar year, is prorated by quarters for a mid-year start, and section 3.03.009 requires the holder to keep it available to present to the building official on request.
Class C Concrete for Curb, Gutter and Approaches
Exhibit 10A, section 3(h) of the subdivision ordinance requires that all curb and gutter, integral curbs, valley gutters, driveway approaches and drainage structures be constructed of Class C, 3,000 psi Portland cement concrete per city standards. That is a specified strength, not a floor to negotiate down from.
We order to it and keep the ticket, because a mix design is the one part of a finished pour nobody can verify by looking at it afterward. On an approach tied into public infrastructure that documentation is what an inspection actually asks to see.
Permit Fees Double If You Start Early
Fee schedule section A4.005 provides that permit fees double in any case where work commences before permits have been obtained, in addition to any civil or criminal fees or penalties. It is the most avoidable cost on any job in this city and it is entirely within a contractor’s control.
Building permits expire 180 days after issuance unless construction continues or an extension is granted, and inspection requests submitted before 4:00 p.m. are performed the next business day. Driveway work on an existing house routes through the city’s Universal Permit Application rather than the new-construction path.
Where the State Takes Over the Approach
Where work touches Interstate 14 and U.S. 190, the city does not set the standard. Subdivision ordinance section 3(f) states that right-of-way and paving width on a limited access freeway are determined by TxDOT rather than by the city, and Bell County falls in the TxDOT Waco District.
An access connection to state right-of-way is permitted by TxDOT on Form 1058 under 43 Texas Administrative Code sections 11.50 through 11.58, and no construction on the right-of-way may begin until the executed permit is received and 24-hour notice given. The FM 439 spur connection of 1.138 miles running southward and westward to Old Nolanville Road puts a second stretch of state right-of-way into the older part of town.
