When it rains, we pour on technology.

A recognized leader in floodplain management, RESPEC protects people and property and balances the challenge of preserving riparian areas, demonstrating environmental stewardship, and sustaining economic development. Using the latest technology in floodplain mapping, such as two-dimensional (2D) modeling, proprietary software, and interactive PDF floodplain maps, our professional team clearly defines the flood risk and communicates complex information and changes to all of the project stakeholders to ensure collaboration and best results.

Through innovative tools and thorough public education, RESPEC delivers a consistent, high-quality process and product. Knowing the wide impact of floodplain studies on the public’s safety, welfare, and finances, RESPEC uses a multi-pronged approach to ensure technically accurate and clear floodplain maps and to provide public outreach by using public meetings, websites, social media, and mailings.  Our data-driven maps for notifying landowners of floodplain changes concisely depict the floodplain changes at a specific property. RESPEC has successfully submitted many Conditional Letter of Map Revisions (CLOMRs) and Letter of Map Revisions (LOMRs) on behalf of clients throughout the US.
