Detention and Mitigation Plans
Stormwater detention and mitigation planning is essential for controlling runoff, protecting surrounding properties, and meeting municipal stormwater regulations. At Norex Engineering, we design custom detention and mitigation systems that help developers and property owners reduce the impact of new construction on local drainage infrastructure.
Our team performs hydrologic and hydraulic analyses to determine how rainfall events affect your site. Based on this data, we size detention basins, retention ponds, and other mitigation structures to slow, store, and safely release stormwater at a controlled rate. We also design associated infrastructure—such as outfall structures, overflow controls, and culverts—to support the entire stormwater management system.
Services include:
Detention and retention basin sizing
Peak flow rate calculations
Pre- vs. post-development runoff modeling
Design of spillways, weirs, and orifice structures
Erosion control measures and energy dissipation
Documentation for city/county drainage and stormwater compliance
Our designs not only meet regulatory requirements but also integrate seamlessly into the surrounding environment. Whether your project is residential, commercial, or industrial, we deliver efficient and sustainable stormwater solutions that protect your site and the community downstream.
