Stormwater Analysis and Design

Lumos has a long history of providing storm drainage, water quality, and flood control design services from master planning to Low Impact Development (LID) implementation to detailed drainage system design and construction oversight. We have expertise applying numerous rainfall/runoff estimation methods and using sophisticated computer programs integrated with GIS technology to perform detailed hydrologic, hydraulic, and water quality modeling. This enables us to predict storm runoff from an individual site or an entire watershed and design storm water infrastructure improvements for projects ranging from municipal storm drain systems to major flood control channels and stream restorations. We have a proven record in developing a wide variety of storm water quality solutions that improve the natural environment by promoting infiltration, filtering out pollutants, minimizing erosion, and reducing downstream runoff.

Our team is knowledgeable in federal, state, and local design guidelines and criteria, and has provided drainage analysis and design services to a multitude of public agencies and private clients across northern Nevada and California.

Lumos understands the uniqueness of stormwater projects and the complexities of hydrology and hydraulics often associated with a given study area or stormwater system. To deliver successful solutions to our clients, we place importance on conducting a comprehensive inventory of the major existing stormwater infrastructure in the area. This process involves reviewing previous drainage studies, analyzing the area's current hydrology, identifying any capacity or operational deficiencies within the existing storm drainage system, recognizing erosion control and water quality enhancement opportunities, designing tailored stormwater quality infrastructure solutions, and finally, providing a detailed stormwater study document designed for years to come.

Our range of services includes: Hydrologic Analysis, Advanced 1D/2D Hydraulic Modeling, Storm Drainage Master Plans, Storm Drain System Design, Open Channel Design, Culvert and Bridge Design, Flood Control Structures, FEMA Floodplain Analysis (including CLOMRs and LOMRs), Scour Analysis, Erosion Control, Plans and Specifications, Low Impact Development/and Stormwater Quality Design, Levee and Floodwall Design, Detention Basin Design, Dam Rehabilitation Design and Breach Analysis, Asset Management, and Stormwater Management BMPs.
