Surface Water

At Kimley-Horn, we deliver integrated surface water solutions that protect communities, restore ecosystems, and support infrastructure across the country.

With a nationwide presence and as a full-service, multidisciplinary firm, our teams help clients navigate complex water challenges with innovative and cost-effective strategies—from planning through implementation.

Effective Water Resources Management

We combine engineering precision with environmental stewardship to deliver sustainable, compliant solutions in flood control, water quality, and permitting. Through green infrastructure and low-impact development, like rain gardens, bioswales, and permeable pavements, we enhance both water quality and community character. Our stream restoration and wetlands experts advance ecosystem health and regulatory goals of federal, state, and local agencies.

From Master Planning to Implementation

Managing the interconnected challenges of stormwater runoff, storage, stream restoration, and water quality treatment demands a comprehensive, systems-level approach. Our team applies advanced hydrologic and hydraulic (H&H) modeling, watershed-scale analysis, and sustainable design practices to develop effective, cost-efficient strategies. These solutions support regulatory compliance and resilient infrastructure outcomes for water management districts, municipalities, and private clients across the nation. Our engineers, planners, landscape architects, environmental scientists, and grants and funding specialists collaborate to provide comprehensive solutions from inception to implementation.

Solutions for All Project Types

Water management considerations are embedded early in every project—from roadway design to high-end retail development—to ensure compliance, resilience, and reliable project delivery. Our methodology combines vulnerability assessments, nature-based design solutions for coastal and urban settings, and integrated hydrologic modeling to evaluate performance and support sustainable, long-term outcomes.
