Flood Studies and Downstream Assessments

As our communities progress with new land development, it is important to understand existing flood prone areas and potential future floodplain areas that are created as a result of these developments. We provide solutions to maximize the development potential of the property, while not adversely impacting the watershed. We are the trusted advisor for our clients as it relates to riverine and storm drain infrastructure flooding.

FEMA Letters of Map Change (LOMC)

Keeping community flood maps up to date with FEMA can be challenging. We lead the project through the regulatory process for our clients.  Our relationships with FEMA and our knowledge of the process saves our clients time, which saves them money.

Detention Sizing

Above ground detention ponds, underground detention ponds, and dams pose both benefits and risks to the public. Our experts get involved when simplistic engineering solutions do not suffice for the proposed development.

Dam Breach Analyses

The threat of a dam breaching is something a community homeowner should not have to think about. At Cardinal Strategies, we not only think about how a dam breach could occur, we also develop analyses, emergency action plans, and operation and maintenance plans for the responsible party.

I trust Cardinal Strategies to take care of all of my flood studies, LOMRs, and FEMA related issues at Shaddock Development Company. They are very competent and have quick turnarounds on flood related issues that can significantly delay your project. In addition, their relationships with FEMA and municipalities are crucial to getting approvals in a timely manner.
