Service Overview

Drainage Planning

Drainage and stormwater systems play a critical role in protecting public safety, infrastructure, and the natural environment. Our drainage engineers support projects from concept development through permitting and construction, working closely with in-house civil designers, surveyors, structural engineers, traffic specialists, and environmental professionals.

Compliant Stormwater Design

Our team designs storm sewer systems, detention facilities, pump stations, and water quality best management practices that meet IDOT, Tollway, IDNR, and local stormwater requirements while remaining constructible, cost-effective, and maintainable. By understanding local ordinances, regional hydrology, and agency expectations, CBBEL helps clients move efficiently through review and permitting while delivering drainage solutions that protect both infrastructure investments and surrounding communities.
