  • WHAT: Brewery Parking Lots
  • WHERE: Houston, TX
  • SIZE: 36,000 sq. ft.

Houston’s oldest microbrewery had a parking problem. As Saint Arnold’s business has grown, so did their parking needs. The brewery is located near Downtown Houston with limited space. Two expansion lots had serious problems.

Parking lot 1 had old cracked concrete, serious flooding and pooling issues and needed to be replaced. Remediation was needed for contaminated soil under and around the lot from old industrial activity on the site.

Parking lot 2 was to be redesigned to remove torn up asphalt as well as replace some of the green space that was needed for parking. Budget and expensive land made retention/detention and drainage a costly proposition.

Project Scope

Cracked concrete and contaminated soil were removed from parking lot 1. After grading 6" of recycled road, base was laid and compacted. The grid was installed and filled with 3/4" clean limestone. Parking stripes were painted for marking spots and remain incredibly visible 18 months later without maintenance. Parking Lot 2 required removal of broken asphalt and some dead grassy medians. The same procedure was followed with Lot 1. No additional drainage or retention elements were added apart from the TRUEGRID system.


By using TRUEGRID permeable with a 6" recycled road base sub-base and #57 rock fill (3/4" crushed limestone), 100 percent land use and maximum lot utilization and efficiency was achieved. More cars fit safely in the lots. Storm water is managed and retained in the lot after the heaviest downpours while the surface is dry. No more stepping into puddles when you exit your vehicle so customers are happy.

Nothing says success like a repeat customer. Saint Arnold ordered TRUEGRID for their second parking lot about eight months after the first TRUEGRID lot completion.


Due to the TRUEGRID installation, the land value went up to $22,176. Retention and drainage costs total of $35,000 were avoided and $64,800 were saved due to TRUEGRID used alternatively to concrete. Total savings from the entire project rose up to $121,976.
