Montgomery County reviews building codes to mitigate flood risks for new developments

The Montgomery County, Maryland, TE Committee held a worksession on March 17, 2025, focusing on critical discussions surrounding planning and building codes, particularly in relation to flood risk management and infrastructure development. The meeting addressed the need for updated regulations to accommodate new construction in flood-prone areas, emphasizing the importance of elevating first floors and managing impervious surfaces.

The committee began by reviewing the planning process for demolition permits, highlighting concerns about rebuilding homes that significantly increase impervious surfaces, which can exacerbate water runoff issues. Members discussed the necessity of integrating flood mitigation strategies into long-term planning and development projects, noting the ongoing debate about who bears the responsibility for these measures.

A key point raised was the impact of larger homes on local infrastructure, particularly in areas experiencing growth, such as Silver Spring and Sligo. The committee acknowledged that while new homes may not be directly regulated, their contribution to increased runoff is a pressing concern that must be addressed proactively.

Additionally, the committee discussed the importance of community outreach regarding flood insurance, suggesting that information be made available in multiple languages to combat scams and ensure residents are well-informed about legitimate options.

The meeting concluded with a commitment to further explore these issues and gather additional data on the financial aspects of water management between Montgomery County and neighboring jurisdictions. The discussions underscored the need for a collaborative approach to effectively manage growth and mitigate flooding risks in the community.
