On a 10,000 cf project, that is the difference between removing 350 cubic yards of soil and 1,100 cubic yards. At $15\u2013$25 per cubic yard for excavation and disposal, the smaller dig often offsets the higher material cost entirely.<\/p>\n\n\n\n<p>One honest note: if your site has available acreage and no traffic loading requirement, a surface detention basin is the most cost-effective choice by a wide margin.

Module resin is tested per ASTM F2418 by TRI Environmental (Austin, TX). State-level compliance varies: California mandates LID infiltration where soils allow, Texas\/Houston requires on-site detention to cap peak discharge at pre-development rates, and Florida requires first-flush volume capture. Confirm requirements with your local stormwater authority \u2014 every jurisdiction writes its own rules.<\/p><\/div><\/div><div class=\"wp-block-uagb-faq-child uagb-faq-child__outer-wrap uagb-faq-item uagb-block-beeb9161 \" role=\"tab\" tabindex=\"0\"><div class=\"uagb-faq-questions-button uagb-faq-questions\">\t\t\t<span class=\"uagb-icon uagb-faq-icon-wrap\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 320 512\"><path d=\"M310.6 246.6l-127.1 128C176.4 380.9 168.2 384 160 384s-16.38-3.125-22.63-9.375l-127.1-128C.2244 237.5-2.516 223.7 2.438 211.8S19.07 192 32 192h255.1c12.94 0 24.62 7.781 29.58 19.75S319.8 237.5 310.6 246.6z\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t<span class=\"uagb-icon-active uagb-faq-icon-wrap\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 320 512\"><path d=\"M27.66 224h264.7c24.6 0 36.89-29.78 19.54-47.12l-132.3-136.8c-5.406-5.406-12.47-8.107-19.53-8.107c-7.055 0-14.09 2.701-19.45 8.107L8.119 176.9C-9.229 194.2 3.055 224 27.66 224z\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/span>\n\t\t\t<span class=\"uagb-question\"><strong>Can I use these modules for an Infiltration Basin or Dry Well?<\/strong><\/span><\/div><div class=\"uagb-faq-content\"><p>Yes.
