​At CHESIEMES Group, our commitment to sustainability and environmental risk management continues to shape our presence on key industry platforms. This month of April 2025, our lead engineer, who also serves as President of the Risk, Emergency and Disaster Management Commission (CMRED) and has served as Past President of the Environmental Engineers Institute (IIAM, in Spanish) at the Professional College of Engineers and Land Surveyors (CIAPR, in Spanish), Hanna Rodríguez, PE, CSP, was invited to speak at two major events that reflect the scope and depth of our firm’s capabilities.

At the 2025 National Watershed and Stormwater Conference, hosted by the Center for Watershed Protection, Hanna shared practical lessons from our team’s on-the-ground experience with Construction General Permits (CGP) and Multi-Sector General Permits (MSGP). Her session, titled “Adapting Stormwater Compliance to a Changing Climate: Lessons from CGP and MSGP Implementation in Tropical Watersheds”, emphasized the importance of tailoring stormwater compliance strategies to Puerto Rico’s unique climate challenges—highlighting our firm’s role in promoting sustainable watershed management through real-world applications.
​​
​The experience served for productive and engaging dialogue with colleagues, focusing on a concept our team is interested in evaluating for the future: the potential of stormwater infrastructure as a utility.

Most recently, the educational event "Cada Segundo Cuenta en el Manejo de una Emergencia", organized by the Puerto Rico Chamber of Commerce this past Thursday, April 24, 2025, Hanna participated in the panel on Mental Health and Risk Management. Representing both our firms and the CIAPR CMRED, she offered insight into how our multidisciplinary team integrates emergency preparedness, disaster response, and occupational health protocols to support public and private sector resilience.

From stormwater solutions to strategic emergency planning, these events showcased our team’s leadership in shaping safer, sustainable, and climate-adaptive practices—true to our mission of delivering integrated environmental engineering and risk management services across Puerto Rico and beyond. At CHESIEMES Group, we remain committed to preparing our communities and industries for a resilient and sustainable future, one project and one conversation at a time. 🌎

In February 2025, our firm had the honor of participating in the 2nd Congreso de Educación Ambiental, Cambio Climático y Desarrollo Sostenible (2nd Congress on Environmental Education, Climate Change and Sustainable Development), hosted by the University of Puerto Rico’s Faculty of Education. Representing our team, Environmental Engineer and CIAPR Commission President Hanna K. Rodríguez Morales led an engaging session titled:

“Innovación Tecnológica y Adaptación al Cambio Climático: Oportunidades y Retos para Puerto Rico y el Caribe.”
“Technological Innovation and Adaptation to Climate Change: Opportunities and Challenges for Puerto Rico and the Caribbean.”

🎯 The goal: To empower Puerto Rico’s K-12 educators with real-world tools and examples that can inspire environmental awareness and climate resilience in their classrooms.​
​
From Google Earth Timelapse to NOAA storm imagery and platforms like EPA’s MyEnvironment, the session bridged engineering expertise with accessible teaching strategies. Participants explored how artificial intelligence, remote sensing, and supercomputing are already being used to model hurricanes, monitor coastal erosion, and evaluate infrastructure vulnerabilities — all with implications for science, geography, and civics education in our archipelago.

Educators walked away with strategies to integrate climate data, spatial tools, and innovative technologies into their daily teaching, aligned with UNESCO’s Education for Sustainable Development goals.
💡As engineers committed to advancing education and environmental resilience, the CHESIEMES Team believes in educating educators — because building climate-ready communities starts in the classroom.

Our team at CHES/IEMES is OK! (Thanks to all who have reached out.)
As you may already know, Hurricane Fiona brought relentless amounts of water and wind to the archipelago of Puerto Rico. Each member of our team has been accounted for and have been blessed with minimal damage, if any, to our properties.
Today, Tuesday, September 20th, 2022, we are all in the process of reaching out to our recurring clients/vendors and contemplating ways in which they all need our assistance. Already re-scheduling trainings yet scheduling necessary inspections or aid, if so necessary.
Our team is also involved in the Risk, Emergency, and Disaster Management Commission (CMRED, in Spanish) of the Professional College of Engineers and Land Surveyor (CIAPR, in Spanish), through which we will be coordinating aid events and efforts. The administration at CHES/IEMES is providing time, resources, and assistance to our team for assuring business continuity as well as opportunities for integration of such response or recovery efforts.
