In recognition of National Preparedness Month, we're sharing some of what we do to help communities better understand and prepare for flood risk.
This work spans the full cycle of flood hazard evaluation: defining hazards, assessing risks and consequences, identifying warning technology, evaluating costs, and recommending practical improvements. We've spent decades helping communities prepare for flooding, completing thousands of floodplain analyses, forecasting studies, and delineation projects.
Our Flood Warning and Forecasting services include:
💧 Hydrologic & Hydraulic Model Development, Calibration, & Validation
💧 Map Atlases & Consequence Assessment Reports
💧 Flood Insurance Studies & Restudies
💧 Emergency Action Plans
💧 Tabletop Flood Response Exercises
💧 Consequence Assessments
💧 Flood Warning System Planning & Development
💧 Meteorologic & Flow Monitoring System Planning, Construction & Operation
💧 Real-time Floodplain Mapping
💧 RTS/CWMS Implementation
💧 Training & Support
A few recent projects:
• Flash Flood Warning Siren Guide: As a subconsultant to AtkinsRéalis, we supported the Texas Water Development Board (TWDB) in implementing Senate Bill 3, serving as task lead on the Flash Flood Warning Siren Guide. While developed for Texas's 30 flood-prone counties, the guide's coverage of siren system planning, cost and funding considerations, and lifecycle management is a useful reference for any agency evaluating outdoor warning systems: https://www.westconsultants.com/services/flood-warning-forecasting/flash-flood-warning-siren-guide-tx/.
• Amarillo Playa Lakes Flood Warning System: For the City of Amarillo Public Works, we designed and deployed a flood warning system for eight urban playa lakes, an affordable, real-time solution that monitors water levels and shares data through a public website: https://amarillotx.elements360.aem.eco/.
• Flood Warning System for the Chehalis River Basin Flood Authority: We've worked with community groups, Tribes, and local, state, and federal agencies to evaluate flood preparedness in Washington State’s flood-prone Chehalis River Basin, carrying the system from inception through daily operation today. It now collects near real-time hydrometeorological data from more than 300 sensors at 115 locations: https://chehalis.onerain.com/.
• Alternative Flood Early Warning System Guide: We supported TWDB's development of the Alternative Flood Early Warning System (FEWS) Guide as a subconsultant to AtkinsRéalis, helping communities expand roadway and bridge flood monitoring with more affordable, easier-to-maintain systems: https://www.twdb.texas.gov/flood/research/early-warning-system/TWDB_Alternative_Flood_Early_Warning_System_Guide_2025.pdf.
This is an area where we continue to grow, as more communities look to strengthen their preparedness. More on how we can help is on our website: https://www.westconsultants.com/services/flood-warning-forecasting/.
