Overview
What Parking Lot Construction Includes
Parking lot construction in Irving is technically more demanding than parking lots in many other North Texas markets because of the Blackland Prairie clay subgrade that underlies most of the city. The expansive clay swells during wet seasons and contracts during droughts, producing cracking, heaving, and pothole formation in conventional asphalt pavements that were not built on stabilized subgrade. Las Colinas corporate campus parking lots, Irving ISD school parking areas, retail center lots on Beltline Road and MacArthur Boulevard, and industrial facility parking in the Grand Prairie border area all share the same underlying soil challenge. General Contractors of Irving solves that challenge through geotechnical-based pavement design rather than generic paving specifications.
The City of Irving's development code requires grading and drainage permits for commercial parking lot construction above a minimum disturbed area, and all commercial site improvements must comply with the city's post-development stormwater management standards. Irving has experienced flooding in low-lying areas during heavy rain events, and the city's drainage requirements reflect the need to prevent commercial development from worsening downstream flooding along the West Fork Trinity River tributaries. We design parking lot drainage systems that meet Irving's post-development discharge rate standards, which typically requires on-site detention capacity for new parking lots that increase the percentage of impervious surface on a site.
ADA accessibility compliance is a consistent focus on every Irving commercial parking lot project because the city's building inspection program and the Texas Department of Licensing and Regulation both review accessible parking compliance. Commercial parking lots must provide the correct number of accessible stalls for the total lot count, those stalls must be located on the shortest accessible route to the building entrance, accessible stall dimensions and access aisle widths must meet TAS (Texas Accessibility Standards) requirements, and the curb ramps at building entrances must meet ADA slope and landing requirements. We design ADA compliance into the parking lot layout from the beginning rather than retrofitting accessible features after the lot is striped.

Detailed scope
What Parking Lot Construction Includes
Parking lot construction in Irving is a coordinated civil and paving scope that requires geotechnical coordination, drainage engineering, and ADA accessibility design from the beginning. The elements below represent the full scope we manage from site assessment through final striping and inspection.
Geotechnical coordination — review of the existing soil conditions report or commissioning a new geotechnical investigation to determine subgrade stabilization depth and pavement section requirements for the Irving clay site.
Subgrade preparation and stabilization — lime or cement treatment of the Blackland Prairie clay, proofroll verification of soft spots, and density testing before base course placement.
Base course and pavement installation — compacted granular base course in tested lifts, followed by asphalt or concrete pavement in the section and thickness specified by the civil engineer for the site's loads and drainage requirements.
Drainage system construction — parking lot grading to drain at minimum 2 percent slope toward inlets, storm inlet installation, underground pipe system, and connection to the City of Irving storm sewer or on-site detention basin.
ADA accessible stall layout and curb ramp construction — Texas Accessibility Standards-compliant accessible stall count, dimensions, and signage, with curb ramps at all accessible routes from the parking lot to building entrances.
Striping, signage, and surface marking — parking stall striping, directional arrows, fire lane designation, accessible stall and access aisle markings, and wheel stop installation per the site plan.
Process
Our Parking Lot Construction Process
Parking lot projects in Irving follow a civil and paving sequence that begins with subgrade assessment and ends with ADA striping inspection. The steps below reflect how we manage that process for Las Colinas corporate campuses, Irving ISD facilities, retail centers, and industrial sites throughout the Irving market.
Step
Geotechnical review and pavement section design
We begin every parking lot project by reviewing the existing geotechnical data or commissioning a new soil investigation if the site data is not current. The geotechnical report drives the stabilization depth, the base course thickness, and the surface course design. For Las Colinas corporate campus parking lots serving Fortune 500 tenants who expect their parking areas to perform for 15 to 20 years without major rehabilitation, we specify subgrade treatment and pavement sections that are sized conservatively rather than minimally.
Step
City of Irving permit submission and drainage coordination
The City of Irving grading and drainage permit requires a drainage study that demonstrates the post-development stormwater discharge rate does not exceed the pre-development rate for the design storm. For parking lots that increase site imperviousness, that typically means designing and building on-site detention capacity — either a detention basin or an underground detention system beneath the parking lot. We work with the civil engineer to size the detention system and submit the drainage study with the permit application.
Step
Subgrade stabilization and base course preparation
After the permit is issued and the site is rough graded to the design elevation, lime or cement is spread and incorporated into the clay subgrade at the geotechnical-specified application rate. The stabilized subgrade is cured, proofrolled, and density-tested. Granular base course is placed and compacted in lifts with density testing at each lift. This preparation sequence is the step that distinguishes a parking lot that will perform reliably on Irving clay from one that will begin cracking and heaving within three to five years.
Step
Pavement placement and drainage infrastructure
Asphalt is placed in compacted lifts using a paving machine, with surface course thickness confirmed by core sampling after placement. Concrete lots are placed with reinforcement, control joints, and surface finishing to achieve the specified pavement flatness. Storm inlets and underground drainage pipe are installed concurrently with the base course and pavement to avoid cutting the finished surface for drainage connections. Detention basin excavation and outlet structure installation are coordinated with the paving phase.
Step
Striping, ADA compliance, and final inspection
Parking lot striping is applied after the pavement has cured to the specified surface temperature. ADA accessible stall and access aisle dimensions are verified before striping to confirm TAS compliance. Curb ramps at building entrances are inspected for slope and landing dimensions. City of Irving Building Inspections signs off on the grading and drainage permit at final inspection, and we provide the City with the civil engineer's as-built drainage survey confirming that detention basin volume and outlet structure elevations match the approved design.
Applications
Where Parking Lot Construction Creates Value in the Irving Market
Parking lot construction in Irving serves a range of commercial, institutional, and industrial clients whose facilities depend on reliable, low-maintenance parking infrastructure. The applications below represent where our engineered approach to Irving clay conditions creates the most measurable value.
Project type
Las Colinas Corporate Campus Parking
Fortune 500 corporate campuses in Las Colinas — including the ExxonMobil, Kimberly-Clark, and Fluor office complexes along the MacArthur Boulevard and SH-114 corridors — maintain large surface parking lots that serve thousands of employees. Corporate campus parking lots are under continuous traffic load and are held to aesthetic standards that prevent the cracked, potholed appearance that poor subgrade preparation produces in just a few years on Irving clay. We build corporate campus parking lots to pavement specifications that reflect 15-to-20-year service life expectations, not minimum-compliant paving standards.
Project type
Irving ISD School and Athletic Facility Parking
Irving ISD schools and athletic complexes need parking lots that handle the high peak-traffic loading of school dismissal, Friday night football games, and weekend community events. School parking lots in Irving must meet TEA accessibility standards for campus parking and must manage stormwater in a way that does not direct runoff toward athletic fields or building entrances. We build school parking lots with subgrade stabilization that accounts for the heavy bus traffic loading in bus loop areas and the concentrated pedestrian crossing loads at accessible routes from the lot to campus entrances.
Project type
Retail Center Parking Lot Construction and Rehabilitation
Retail center parking lots on Beltline Road, MacArthur Boulevard, and Story Road in Irving serve both the Hispanic working-class community in central and south Irving and the corporate corridor workforce that stops for errands near the Las Colinas office campuses. Retail parking lots experience high turnover traffic loading concentrated at drive lane intersections and end-of-row turning areas where the pavement section takes the most abuse. We design drive lane pavement sections conservatively and install reinforced concrete at high-wear locations — dumpster pads, entry aprons, and loading areas — to reduce the lifecycle maintenance cost for retail property owners.
Project type
Industrial and Warehouse Employee Parking
Industrial and warehouse facilities in the Grand Prairie border area and the I-635 industrial corridor need employee parking lots that handle shift-change traffic loading and periodic heavy vehicle ingress when delivery trucks use parking areas during off-peak hours. Industrial parking lots are typically built to a lower aesthetic standard than corporate campus or retail lots, but they must still perform structurally on Irving clay without producing safety hazards from pavement cracking or ponding. We specify subgrade stabilization for industrial parking lots based on the actual loading conditions — not a reduced pavement section simply because the aesthetic standard is lower.
Scheduling
Scheduling Parking Lot Construction in Irving
Parking lot construction in Irving is most vulnerable to schedule delays during two seasonal windows: the spring rain season from February through April, when Blackland Prairie clay is saturated and cannot be subgrade-stabilized until it dries sufficiently, and the summer heat peak in July and August, when asphalt placement must be scheduled to avoid thermal cracking during placement and compaction. We account for both seasonal constraints in the project schedule and maintain contingency windows for weather delays so that clients are not surprised by seasonal impacts on paving progress.
For occupied commercial and industrial properties where existing parking lots must remain partially open during construction, we develop phasing plans that keep a minimum number of customer or employee parking spaces available throughout the project. Irving city code requires that accessible parking spaces remain available at all times during construction — they cannot be part of a phased construction closure even temporarily without City approval. We design phasing plans that maintain accessible stalls throughout the project and submit the phasing plan to the City of Irving building department before work begins.

Talk with General Contractors of Irving about parking lot construction in Irving and the Las Colinas commercial market.
Why do parking lots in Irving fail faster than in other DFW markets?
Irving sits on Blackland Prairie clay, which is among the most expansive soil types in North Texas. The clay absorbs moisture and expands during wet seasons, then shrinks and cracks during droughts, producing 3 to 5 inches of vertical movement in untreated soil horizons. Parking lots built without subgrade stabilization on this clay will crack, heave, and pothole within 3 to 7 years regardless of the surface pavement quality. The fix is lime or cement stabilization of the clay subgrade before the base course and surface pavement are placed.
Does commercial parking lot construction in Irving require a City permit?
Yes. The City of Irving requires a grading and drainage permit for commercial parking lot construction above the minimum disturbed-area threshold. New parking lots that increase site imperviousness also require a drainage study demonstrating that post-development stormwater discharge does not exceed the pre-development rate, which usually means designing on-site detention capacity. Projects that disturb more than one acre also require a TCEQ Construction General Permit.
Should I use asphalt or concrete for my Irving parking lot?
Both perform well on properly stabilized Irving clay subgrade. Asphalt is generally less expensive to install initially and is easier to repair locally if localized failures occur, but it requires periodic seal coating and overlay every 10 to 15 years. Concrete is more expensive initially but requires less maintenance over a 20-to-30-year service life and is preferred for areas with concentrated loads — dumpster pads, loading zones, and entry aprons. We recommend hybrid designs that use concrete at high-load and high-wear locations and asphalt in the body of the parking field where maintenance access is easier.
How many ADA accessible spaces are required for an Irving commercial parking lot?
The number of ADA-accessible parking spaces required is set by the total number of spaces in the parking lot under the ADA Standards for Accessible Design and Texas Accessibility Standards. The ratio scales from one accessible space per 25 total spaces for small lots to a diminishing ratio for larger lots, with a minimum of one van-accessible space. Irving's commercial parking lots serving facilities that are open to the public must also have van-accessible stalls with 8-foot access aisles. We confirm the correct accessible stall count and layout for your specific lot as part of our permit preparation.
Can an existing parking lot on Irving clay be rehabilitated rather than fully reconstructed?
Localized patching or overlay of an Irving parking lot that is failing due to clay subgrade movement is a short-term fix that will fail in the same locations within a few years if the underlying clay is not treated. Full reconstruction with subgrade stabilization is the only approach that produces a permanent improvement on Irving clay. However, if the pavement failures are limited to specific areas and the subgrade under the remaining pavement has been stabilized, localized reconstruction of the failed areas may be cost-effective. We evaluate existing conditions with core samples and proofroll testing to determine the most cost-effective approach for each site.
