Construction in a Floodplain

The Moore Group is currently obtaining variances and permits for Construction in a Floodplain for a residential project. Our client owns property that is in a floodplain, and the client wishes to construct improvements to the property. City code normally does not allow for construction in a floodplain, so we are obtaining a variance to allow the construction to proceed.

In order to obtain the variance, we are engineering the project in specific ways that meet city requirements. The city desires to maintain the current stormwater volume within the floodplain. Our proposed construction will use some of the floodplain volume. In order to balance the floodplain volume, we are removing an unneeded structure from the property. We have prepared calculations that show that there is a net increase in floodplain volume as a result of the project.

We are preparing construction plans to raise the foundation of the existing structure and proposed addition to an elevation above the floodplain elevation. Our surveyors will prepare a drainage easement to contain the floodplain. The easement will exclude the building footprint, effectively removing the structure from the floodplain.

We will represent our client at a public hearing before the city council to request the variance. At the public hearing, we will provide justification for the council to grant the variance. We expect to have city staff support for granting the variance. With the support of city staff, there is a good chance the variance will be granted.
