Paving in Dallas County's Oldest Town
Asphalt paving in Adel covers a historic courthouse town that has suddenly grown. Adel was incorporated in 1847 as Penoach, took its current name in 1849, and is the oldest town in Dallas County and its county seat. The Dallas County Courthouse, completed in 1902 for about $109,000, stands at the center of downtown. Adel had 3,435 residents in 2000, 3,682 in 2010 and 6,153 in 2020, an increase of about 67 percent in the last decade alone.
Two kinds of driveway
Adel's older neighborhoods around the courthouse have driveways that have been patched and overlaid for decades. The new subdivisions on the edges have young driveways that mostly need maintenance and settlement repairs. We look at which you have and recommend accordingly.
The North Raccoon River
Adel lies along the North Raccoon River at 892 feet. Lots on lower ground near the river can have wetter soil, which means more base work under the asphalt. We dig out soft spots, use crushed stone, and slope surfaces to drain.
Fastest-growing county
Dallas County grew more than 50 percent from 2010 to 2020, the fastest of any county in Iowa. In Adel that means new streets, new homes and new commercial lots. New lots need maintenance plans from the start: crack sealing, sealcoating and restriping on a schedule.
Downtown and courthouse lots
Businesses and offices around the courthouse square have small, busy lots. We patch, seal and stripe them in phases.
Our approach
We visit, measure, check drainage and give you a written quote that breaks out each part of the job. If the work reaches the street, we confirm the city's requirements before scheduling.
Maintenance
Fill cracks in late summer and seal every few years once the asphalt has cured.
Gravel-to-asphalt in older neighborhoods
Some older Adel homes still have gravel drives or parking pads. Converting to asphalt keeps dust and ruts down and makes snow removal easier. We grade and compact the existing gravel as part of the new base and add stone where it is thin.
Commuters
With Adel's growth driven by commuters to the metro, we plan work so cars can be moved the night before and the driveway is back in use within a few days.
