In this course, Tim Arvin and Mitchell Maxwell will discuss the latest flood maps and its implications on site design and building code design requirements. The team will explore the use of interactive flood maps and the three ways to view maps (Interactive Map, Map Image – FIRM, Dynamic Map – FIRMette). The team will also explain the different federal and local flood regulations, how civil and geotechnical engineers can help evaluate design options, and other factors to consider such as flood insurance, local flood events, etc.

This program will also address the current proposed changes to the DC’s floodplain regulations and how it might affect future development, permitting, and substantial improvement projects within DC.

Presented by:

Tim Arvin, PE
Tim Arvin is a site/civil engineer with over 10 years of experience in the Washington, DC region and overseas. Tim received his Bachelor's in Civil Engineering and Master's in Water Resource Engineering from George Mason University and is a licensed professional engineer in the state of Virginia. Currently, Tim is a project manager at Langan. He leads complex site/civil engineering projects involving site feasibility studies, site layout, grading and drainage design, stormwater management analysis and design, utility design, and design of erosion and sediment control plans. He has extensive project experience in the land development industry, education sector, medical facilities, and international work.

Mitchell Maxwell
Mitchell graduated with a Bachelors of Science in Environmental Engineering and a Master's of Civil Engineering at the University of Delaware. Mitchell moved to the DC metro area with a passion for international work and water infrastructure. He is involved in site/civil engineering designs for both local and international projects. His primary job responsibilities include the development of site plans, utility designs, stormwater management plans, and water resources focused assessments and reports.

Learning Objectives:

• Gain insight into how FEMA Flood Insurance Rate Maps (FIRMs) are created, including data sources, hydrologic and hydraulic modeling techniques, and the map revision process. Learn how to access, interpret, and download the latest official floodplain maps.
• Learn to recognize and differentiate between flood zone designations (e.g., Zones AE, X, VE) shown on flood maps, and understand the general characteristics and risk profiles associated with each zone.
• Understand how floodplain designations influence site layout decisions, grading, foundation types, and stormwater strategies. Learn the relevant building code requirements triggered by floodplain location.
• Discover how civil and geotechnical engineers support design teams by assessing floodplain constraints, providing technical documentation for permits, and proposing site-specific solutions.
