Site engineering in Iowa runs through the DNR's NPDES General Permit No. 2 for construction stormwater, required for sites disturbing an acre or more, with a pollution-prevention plan and erosion controls. Post-construction stormwater management and water-quality requirements are enforced by local governments and, in the metros, adopted stormwater standards that often follow the Iowa Stormwater Management Manual. We design detention, bioretention, and conveyance to those standards, accounting for Iowa's flat-to-rolling terrain, tight clay and loess soils, and agricultural drainage tile that frequently crosses development sites and must be managed or rerouted. Freeze-thaw and deep frost affect pavement and utility design. For the large data-center and processing sites driving Iowa's market, we plan grading and detention to handle sizeable impervious areas while meeting state and local water-quality volumes.
