FEMA DOCUMENTATION / FLOOD STUDIES
Weston & Sampson has completed several flood studies involving hydrologic/hydraulic analyses and stream channel and storm drainage modeling. Our team’s experience includes hydrologic & hydraulic (H&H) modeling related to large-scale watersheds, structures, and several miles of stream improvements. Our expertise includes designs involving storm drainage improvements, culvert replacements, and open channel improvements to relieve flooding and obtain Flood Management Certification permit approvals. Weston & Sampson follows FEMA regulatory compliance for design standards for projects in FEMA flood zones and floodways, and we have extensive experience with FEMA-related regulatory approvals and documentation related to FEMA Conditional Letter of Map Revision (CLOMR) and FEMA Letter of Map Revision (LOMR) approvals.

Using Stormwater Infiltration to Improve Water Quality in Rhode Island - Jim Riordan's article in NEREJ titled, "Using stormwater Infiltration to Improve Water Quality in Rhode Island," describes the Stormwater Best Management Practices that the town of North Providence is implementing to alleviate the flooding and water quality issues in the area.
Modeling & Green Infrastructure Design Helps Reduce Nuisance Flooding in Major Commercial Area - Andrew Walker, PH, CFM and James Pearson, PE co-authored an article in Stormwater Solutions entitled “Modeling & Green Infrastructure Design Helps Reduce Nuisance Flooding in Major Commercial Area." Climate change-driven increases in future precipitation are predicted to make flooding worse, leading to a redesign of the John Fitch Highway that will make the community more climate resilient.
