Safeguard The Design of Buildings and Infrastructure with Garrison Flood Protection Systems

Architects and engineers are the visionaries behind our communities' development and infrastructure and play a pivotal role in shaping our built environments. Yet, even the most brilliant building designs and structures can be compromised by the rising threat of floods.

From designing roadways to planning new developments and retro-fitting existing structures, their expertise ensures that infrastructure is safe, resilient and compliant with FEMA and NFIP Technical Bulletin 3 for Dry Floodproofing against the force and hydrostatic pressure associated with severe flooding.

Garrison Makes it Easy For Your Designs to Comply With FEMA and NFIP Dry Floodproofing Requirements

Flooding has severe impacts due to factors like climate change, urbanization, poor sewer and drainage, and outdated infrastructure. Architects, engineers, property developers and risk compliance designers must prioritize flood control to meet structural and technical requirements.

Garrison will assist in your technical flood plan designs that meet your client’s specific flood mitigation requirements, as well as offer consultations, structural engineering reports, testing, shop drawings and analysis in the design and fabrication of our structurally compliant flood-log or flood barrier systems specifically designed to meet the needs of architects and engineers.

Hammerhead™️ Aluminum Flood Log System

The James Lewis Jr. Eastside Apartments - Charleston, SC

hammerhead aluminum flood barrier project for new building

The new build of this apartment complex is located in a known flood zone in the city of Charleston, South Carolina. Therefore, by code, the city requires a series of measures that ensure buildings within a dedicated flood zone are designed to be safe and protected.

According to the city legislature, building in Charleston flood zones requires an Elevation Certificate, Dry Floodproofing Certificate, V-Zone Breakaway Wall Certificate, V-Zone Design Certificate, as well as compliance with the city matrix of FIRM (Charleston Flood Zones).

Additionally, all new construction’s DFE (Design Flood Elevation) must be equal to the BFE (Base Flood Elevation) plus 2ft of freeboard (City Flood Compliance Matrix). To meet the requirements, Creative Builders Inc., a well-established construction firm was commissioned by the City of Charleston and the Fitch Irick Corporation to build affordable housing for the City in the Eastside neighborhood of Charleston.

The James Lewis Jr. Eastside Apartments consists of 400 residential apartment units as well as retail space and is designed to bring affordable housing to the Charleston peninsula, as well as contribute to the revitalization of the Eastside neighborhood. To meet the requirements of the city the contracted team needed durable and effective flood barriers.
