"No-Rise" Certifications
If your property lies adjacent to a river, creek, wash or other waterway that is prone to flooding, you may be required by law to meet certain requirements to minimize the impact of any new developments on the existing water flows, as well as to mitigate the risk of flood damage to the structures. The process to get approval to construct on the lot is called a "No-Rise Certification". This certification entails determining the existing floodway extents from published flood maps produced by FEMA and/or other sources, then evaluating the impact of any new developments on the flood water conveyance using hydrologic analyses. The objective of the certification is to ensure the new development will not cause the floodwaters to rise which could have negative impacts on the adjacent properties up and downstream. Thus the "no-rise" terminology.
Typically the way this is achieved is by designing buildings to be elevated on columns or on stem walls with vent openings to allow water to flow under the building, thus minimizing any restrictions to the flows. SEC's engineers will coordinate with the architectural and structural designers to develop a design that meets the certification requirements and provide the no-rise certification documentation needed to get the permits for construction.
Below are some examples of "no-rise" construction methods.
